Organization, Consolidation and Presentation of Financial Statements [Abstract] | |
Basis of Presentation | 1. Basis of Presentation The accompanying unaudited condensed consolidated financial statements include the consolidated accounts of PURE Bioscience, Inc. and its wholly owned subsidiary, ETI H2O Inc., a Nevada corporation. ETI H2O, Inc. currently has no business operations and no material assets or liabilities and there have been no significant transactions related to ETI H2O, Inc. during the periods presented in the condensed consolidated financial statements. All inter-company balances and transactions have been eliminated. All references to “PURE,” “we,” “our,” “us” and the “Company” refer to PURE Bioscience, Inc. and our wholly owned subsidiary. The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America, or GAAP, for interim financial information pursuant to the instructions to Form 10-Q and Article 10/Rule 8-03 of Regulation S-X. Accordingly, they do not include all of the information and disclosures required by GAAP for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring adjustments) considered necessary for a fair presentation have been included. Operating results for the quarter ended April 30, 2022 are not necessarily indicative of the results that may be expected for other quarters or the year ending July 31, 2022. The July 31, 2021 balance sheet was derived from audited financial statements but does not include all disclosures required by GAAP and included in our Annual Report on Form 10-K. For more complete information, these unaudited financial statements and the notes thereto should be read in conjunction with the audited financial statements for the year ended July 31, 2021 included in our Annual Report on Form 10-K covering such period filed with the Securities and Exchange Commission, or SEC, on October 28, 2021. The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and the accompanying notes. Actual results could differ from those estimates. |

Liquidity And Going Concern | |
Liquidity and Going Concern | 2. Liquidity and Going Concern We have a history of recurring losses, and as of April 30, 2022 we have incurred a cumulative net loss of $ 128,051,000 2,258,000 1,441,000 1,879,000 511,000 Our future capital requirements depend on numerous forward-looking factors. These factors may include, but are not limited to, the following: the acceptance of, and demand for, our products; our success and the success of our partners in selling our products; our success and the success of our partners in obtaining regulatory approvals to sell our products; the costs of further developing our existing products and technologies; the extent to which we invest in new product and technology development; and the costs associated with the continued operation, and any future growth, of our business. The outcome of these and other forward-looking factors will substantially affect our liquidity and capital resources. Until we can continually generate positive cash flow from operations, we will need to continue to fund our operations with the proceeds of offerings of our equity and debt securities. However, we cannot ensure that additional financing will be available when needed or that, if available, financing will be obtained on terms favorable to us or to our stockholders. If we raise additional funds from the issuance of equity securities, substantial dilution to our existing stockholders would likely result. If we raise additional funds by incurring debt financing, the terms of the debt may involve significant cash payment obligations as well as covenants and specific financial ratios that may restrict our ability to operate our business. |

Accounting Policies [Abstract] | |
Significant Accounting Policies | 3. Significant Accounting Policies Revenue Recognition We account for revenue in accordance with Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”), Topic 606, Revenue from Contracts with Customers (“Topic 606”). Under Topic 606, revenue is recognized at an amount that reflects the consideration to which we expect to be entitled in exchange for transferring goods or services to a customer. This principle is applied using the following 5-step process: 1. Identify the contract with the customer 2. Identify the performance obligations in the contract 3. Determine the transaction price 4. Allocate the transaction price to the performance obligations in the contract 5. Recognize revenue when (or as) each performance obligation is satisfied Under Topic 606, we recognize revenue when we satisfy a performance obligation by transferring control of the promised goods or services to our customers, in an amount that reflects the consideration we expect to be entitled to in exchange for those goods or services. Our technology platform is based on patented stabilized ionic silver, and our initial products contain silver dihydrogen citrate, or SDC. SDC is a broad-spectrum, non-toxic antimicrobial agent, which offers 24-hour residual protection and formulates well with other compounds. We sell various configurations and dilutions of SDC direct to customers and through distributors. We currently offer PURE ® ® Contract terms for unit price, quantity, shipping and payment are governed by sales agreements and purchase orders which we consider to be a customer’s contract in all cases. The unit price is considered the observable stand-alone selling price for the arrangements. Any promotional or sales discounts are applied evenly to the units sold for purposes of calculating standalone selling price. Product sales generally consist of a single performance obligation that we satisfy at a point in time. We recognize product revenue when the following events have occurred: (a) we have transferred physical possession of the products, (b) we have a present right to payment, (c) the customer has legal title to the products, and (d) the customer bears significant risks and rewards of ownership of the products. Our direct customer and distributor sales are invoiced based on received purchase orders. Our payment terms on invoiced direct customer and distributor sales range between 30 and 90 days after we satisfy our performance obligation. The majority of our customers are on 30 day payment terms. We currently offer no right of return on invoiced sales and maintain no allowance for sales returns. Shipping and handling are treated as activities to fulfill promises to customers and any amounts billed to a customer, if applicable, represent revenues earned for the goods provided. Costs related to such shipping and handling billings are classified as cost of sales. We do not have significant categories of revenue that may impact how the nature, amount, timing and uncertainty of revenue and cash flows are affected by economic factors. A summary of our revenue by product type for the nine months ended April 30, 2022 and 2021 is as follows: Summary of Revenue by Product April 30, 2022 2021 PURE Hard Surface $ 1,158,000 $ 2,815,000 SILVÉRION 251,000 26,000 Total $ 1,409,000 $ 2,841,000 A summary of our revenue by product type for the three months ended April 30, 2022 and 2021 is as follows: April 30, 2022 2021 PURE Hard Surface $ 352,000 $ 556,000 SILVÉRION 145,000 — Total $ 497,000 $ 556,000 Variable Consideration We record revenue from customers in an amount that reflects the transaction price we expect to be entitled to after transferring control of those goods or services. From time to time, we offer sales promotions on our products such as discounts. Variable consideration is estimated at contract inception only to the extent that it is probable that a significant reversal of revenue will not occur. Use of Estimates The preparation of consolidated financial statements in conformity with accounting principles generally accepted in the United States of America, or GAAP, requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements, and the disclosures made in the accompanying notes to the consolidated financial statements. Actual results could differ materially from those estimates. Those estimates and assumptions include estimates for reserves of uncollectible accounts, inventory obsolescence, depreciable lives of property and equipment, analysis of impairments of recorded long-term tangible and intangible assets, realization of deferred tax assets, accruals for potential liabilities and assumptions made in valuing stock instruments issued for services. Net Loss Per Share Basic net loss per common share is computed as net loss divided by the weighted average number of common shares outstanding for the period. Our diluted net loss per common share is the same as our basic net loss per common share because we incurred a net loss during each period presented, and the potentially dilutive securities from the assumed exercise of all outstanding stock options, restricted stock units, and warrants would have an anti-dilutive effect. As of April 30, 2022 and 2021, stock options, warrants and shares issuable under restricted stock unit awards of 7,391,625 10,358,765 Schedule of Anti-dilutive Securities Excluded from Computation of Earnings Per Share April 30, 2022 2021 Common stock options 6,179,125 8,018,500 Restricted stock units 1,212,500 2,012,500 Warrants — 327,765 Total 7,391,625 10,358,765 Inventory Inventories are stated at the lower of cost or net realizable value, and net of a valuation allowance for potential excess or obsolete material. Cost is determined using the average cost method. Depreciation related to manufacturing is systematically allocated to inventory produced, and expensed through cost of goods sold at the time inventory is sold. Inventories consist of the following: Schedule of Inventories April 30, 2022 July 31, 2021 Raw materials $ 17,000 $ 17,000 Finished goods 284,000 315,000 Inventories $ 301,000 $ 332,000 Share-Based Compensation We periodically issue stock options and restricted stock awards to employees and non-employees in non-capital raising transactions for services and for financing costs. We account for such grants issued and vesting to employees based on ASC 718, whereby the value of the award is measured on the date of grant and recognized as compensation expense on the straight-line basis over the vesting period. We estimate the fair value of share-based payment awards at the date of grant using the Black-Scholes option valuation model. The Black-Scholes option valuation model requires the input of subjective assumptions, including price volatility of the underlying stock, risk-free interest rate, dividend yield, and expected life of the option. Share-based compensation expense is based on awards ultimately expected to vest, and therefore is reduced by expected forfeitures. Impairment of Long-Lived Assets In accordance with GAAP, if indicators of impairment exist, we assess the recoverability of the affected long-lived assets by determining whether the carrying value of such assets can be recovered through undiscounted future operating cash flows. If impairment is indicated, we measure the amount of such impairment by comparing the carrying value of the asset to the fair value of the asset and we record the impairment as a reduction in the carrying value of the related asset and a charge to operating results. Estimating the undiscounted future cash flows associated with long-lived assets requires judgment, and assumptions could differ materially from actual results. During the three and nine months ended April 30, 2022 and 2021, no impairment of long-lived assets was indicated or recorded.

Accounting Changes and Error Corrections [Abstract] | |
Recent Accounting Pronouncements | 4. Recent Accounting Pronouncements In June 2016, the FASB issued ASU No. 2016-13, Credit Losses - Measurement of Credit Losses on Financial Instruments (“ASC 326”). The standard significantly changes how entities will measure credit losses for most financial assets, including accounts and notes receivable. The standard will replace today’s “incurred loss” approach with an “expected loss” model , under which companies will recognize allowances based on expected rather than incurred losses. Entities will apply the standard’s provisions as a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the guidance is effective. As small business filer, the standard will be effective for us for interim and annual reporting periods beginning after December 15, 2022. The Company is currently assessing the impact of adopting this standard on the Company’s financial statements and related disclosures. In August 2020, the FASB issued ASU No. 2020-06 (“ASU 2020-06”) “Debt—Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging—Contracts in Entity’s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity.” ASU 2020-06 will simplify the accounting for convertible instruments by reducing the number of accounting models for convertible debt instruments and convertible preferred stock. Limiting the accounting models will result in fewer embedded conversion features being separately recognized from the host contract as compared with current GAAP. Convertible instruments that continue to be subject to separation models are (1) those with embedded conversion features that are not clearly and closely related to the host contract, that meet the definition of a derivative, and that do not qualify for a scope exception from derivative accounting and (2) convertible debt instruments issued with substantial premiums for which the premiums are recorded as paid-in capital. ASU 2020-06 also amends the guidance for the derivatives scope exception for contracts in an entity’s own equity to reduce form-over-substance-based accounting conclusions. ASU 2020-06 will be effective January 1, 2024, for the Company. Early adoption is permitted, but no earlier than January 1, 2021, including interim periods within that year. Management is currently evaluating the effect of the adoption of ASU 2020-06 on the consolidated financial statements, but currently does not believe ASU 2020-06 will have a significant impact on the Company’s accounting. In May 2021, the FASB issued ASU 2021-04, Earnings Per Share (Topic 260), Debt — Modifications and Extinguishments (Subtopic 470-50), Compensation — Stock Compensation (Topic 718), and Derivatives and Hedging — Contracts in Entity’s Own Equity (Subtopic 815-40): Issuer’s Accounting for Certain Modifications or Exchanges of Freestanding Equity-Classified Written Call Options (“ASU 2021-04”). ASU 2021-04 provides guidance as to how an issuer should account for a modification of the terms or conditions or an exchange of a freestanding equity-classified written call option (i.e., a warrant) that remains classified after modification or exchange as an exchange of the original instrument for a new instrument. An issuer should measure the effect of a modification or exchange as the difference between the fair value of the modified or exchanged warrant and the fair value of that warrant immediately before modification or exchange and then apply a recognition model that comprises four categories of transactions and the corresponding accounting treatment for each category (equity issuance, debt origination, debt modification, and modifications unrelated to equity issuance and debt origination or modification). ASU 2021-04 is effective for all entities for fiscal years beginning after December 15, 2021, including interim periods within those fiscal years. An entity should apply the guidance provided in ASU 2021-04 prospectively to modifications or exchanges occurring on or after the effective date. Early adoption is permitted for all entities, including adoption in an interim period. If an entity elects to early adopt ASU 2021-04 in an interim period, the guidance should be applied as of the beginning of the fiscal year that includes that interim period. The adoption of ASU 2021-04 is not expected to have any impact on the Company’s consolidated financial statement presentation or disclosures. Recent accounting pronouncements issued by the FASB, including its Emerging Issues Task Force, the American Institute of Certified Public Accountants, and the Securities and Exchange Commission did not or are not believed by management to have a material impact on the Company’s present or future consolidated financial statement presentation or disclosures. |

Stockholders’ Equity | 6. Stockholders’ Equity Restricted Stock Units The Company issues restricted stock unit awards (“RSUs”) to key management and as compensation for services to consultants and others. The RSUs typically vest over a two-year period and carry a ten-year term. Each RSU represents the right to receive one share of common stock, issuable at the time the RSU subsequently settles, as set forth in the Restricted Stock Unit Agreement. The Company determines that fair value of those awards at the date of grant, and amortizes those awards as an expense over the vesting period of the award. The shares earned under the grant are usually issued when the award settles at the end of the term. On October 4, 2018, the Board of Directors appointed Tom Myers as the Company’s Chief Operating Officer. In connection with Mr. Myers appointment, the Board agreed to grant him 500,000 500,000 As of July 31, 2021, the Company had granted 2,012,500 1,679,167 333,333 144,000 During the nine months ended April 30, 2022 and 2021, the Company recognized $ 62,000 three year 82,000 333,333 1.0 During the nine months ended April 30, 2022, 800,000 1,212,500 879,167 A summary of our restricted stock unit activity and related data is as follows: Schedule of Restricted Stock Activity Total RSU Vested and Outstanding at July 31, 2021 2,012,500 1,679,167 Granted — — Issued (800,000 ) (800,000 ) Forfeited — — Outstanding at April 30, 2022 1,212,500 879,167 Stock Option Plans 2007 Equity Incentive Plan In February 2016, we amended and restated our 2007 Equity Incentive Plan, the (“2007 Plan”), to, among other changes, increase the number of shares of common stock issuable under the 2007 Plan by 4,000,000 February 4, 2026 10 1,552,000 2017 Equity Incentive Plan In January 2021, we amended and restated our 2017 Equity Incentive Plan, the (“2017 Plan”), to, among other changes, increase the number of shares of common stock issuable under the 2017 Plan by 5,000,000 10 3,755,000 During the nine months ended April 30, 2022, we authorized the issuance of 170,000 36,000 one three years ten year 60,000 48,000 one year five year A summary of our stock option activity is as follows: Schedule of Stock Option Activity Shares Weighted- Aggregate Outstanding at July 31, 2021 8,644,125 $ 0.76 $ 124,000 Granted 170,000 $ 0.29 2,000 Exercised — $ — — Expired (2,635,000 ) $ 1.05 — Outstanding at April 30, 2022 6,179,125 $ 0.62 $ — The weighted-average remaining contractual term of options outstanding at April 30, 2022 was 6.64 At April 30, 2022, options to purchase 5,466,625 0.64 6.31 150,000 0.83 For the nine months ended April 30, 2022 share-based compensation expense for stock options that vested during the period was $ 431,000 621,000 We use the Black-Scholes valuation model to calculate the fair value of stock options. Stock-based compensation expense is recognized over the vesting period using the straight-line method. The fair value of stock options was estimated at the grant date using the following weighted average assumptions: Schedule of Fair Value Assumptions Nine Months Ended April 30, 2022 Nine Months Ended April 30, 2021 Volatility 88.35 % 104.93 % Risk-free interest rate 1.17 % 0.18 % Dividend yield 0.0 % 0.0 % Expected life 5.59 2.81 Volatility is the measure by which our stock price is expected to fluctuate during the expected term of an option. Volatility is derived from the historical daily change in the market price of our common stock, as we believe that historical volatility is the best indicator of future volatility. The risk-free interest rates used in the Black-Scholes calculations are based on the prevailing U.S. Treasury yield as determined by the U.S. Federal Reserve. We have never paid dividends on our common stock and do not anticipate paying dividends on our common stock in the foreseeable future. Accordingly, we have assumed no dividend yield for purposes of estimating the fair value of our share-based compensation. The expected life of options was estimated using the average between the contractual term and the vesting term of the options. |

Commitments and Contingencies | 8. Commitments and Contingencies COVID-19 The COVID-19 pandemic has led to severe disruptions in general economic activities, as businesses and federal, state, and local governments take increasingly broad actions to mitigate this public health crisis. While we have experienced some delays related to final third-party validation of certain of our products and product rollouts by customers using PURE Control, we have not experienced a material disruption to our business. In addition, we previously benefited from increased demand from our customers for our PURE Hard Surface product due to a focus on surface disinfecting in response to attempting to prevent COVID-19 transmission. We subsequently experienced an abatement in such demand and cannot assure you that demand will stabilize. Additionally, we are beginning to experience supply chain issues with our various plastic packaging configurations and citric acid. Further, on a go-forward basis, we cannot guarantee the overall economic conditions will not affect our business, as these conditions may significantly negatively impact all aspects of our business. Our business is dependent on the continued health and productivity of our employees, including our sales staff and corporate management team. Additionally, our liquidity could be negatively impacted if these conditions continue for a significant period of time and we may be required to pursue additional sources of financing to obtain working capital, maintain appropriate inventory levels, and meet our financial obligations. Currently, capital and credit markets have been disrupted by the crisis and our ability to obtain any required financing is not guaranteed and largely dependent upon evolving market conditions and other factors. Depending on the continued impact of the crisis, further actions may be required to improve our cash position and capital structure. The extent to which the COVID-19 pandemic ultimately impacts our business, sales, results of operations and financial condition will depend on future developments, which are highly uncertain and cannot be predicted, including, but not limited to, the duration and spread of the outbreak, its severity, the actions to contain the virus or treat its impact, and how quickly and to what extent normal economic and operating conditions resume and, more specifically, the effect it has on our customers and suppliers. Even after the COVID-19 pandemic has subsided, we may experience significant impacts to our business as a result of its global economic impact, including any economic downturn or recession that has occurred or may occur in the future. |

Accounting Policies [Abstract] | |
Revenue Recognition | Revenue Recognition We account for revenue in accordance with Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”), Topic 606, Revenue from Contracts with Customers (“Topic 606”). Under Topic 606, revenue is recognized at an amount that reflects the consideration to which we expect to be entitled in exchange for transferring goods or services to a customer. This principle is applied using the following 5-step process: 1. Identify the contract with the customer 2. Identify the performance obligations in the contract 3. Determine the transaction price 4. Allocate the transaction price to the performance obligations in the contract 5. Recognize revenue when (or as) each performance obligation is satisfied Under Topic 606, we recognize revenue when we satisfy a performance obligation by transferring control of the promised goods or services to our customers, in an amount that reflects the consideration we expect to be entitled to in exchange for those goods or services. Our technology platform is based on patented stabilized ionic silver, and our initial products contain silver dihydrogen citrate, or SDC. SDC is a broad-spectrum, non-toxic antimicrobial agent, which offers 24-hour residual protection and formulates well with other compounds. We sell various configurations and dilutions of SDC direct to customers and through distributors. We currently offer PURE ® ® Contract terms for unit price, quantity, shipping and payment are governed by sales agreements and purchase orders which we consider to be a customer’s contract in all cases. The unit price is considered the observable stand-alone selling price for the arrangements. Any promotional or sales discounts are applied evenly to the units sold for purposes of calculating standalone selling price. Product sales generally consist of a single performance obligation that we satisfy at a point in time. We recognize product revenue when the following events have occurred: (a) we have transferred physical possession of the products, (b) we have a present right to payment, (c) the customer has legal title to the products, and (d) the customer bears significant risks and rewards of ownership of the products. Our direct customer and distributor sales are invoiced based on received purchase orders. Our payment terms on invoiced direct customer and distributor sales range between 30 and 90 days after we satisfy our performance obligation. The majority of our customers are on 30 day payment terms. We currently offer no right of return on invoiced sales and maintain no allowance for sales returns. Shipping and handling are treated as activities to fulfill promises to customers and any amounts billed to a customer, if applicable, represent revenues earned for the goods provided. Costs related to such shipping and handling billings are classified as cost of sales. We do not have significant categories of revenue that may impact how the nature, amount, timing and uncertainty of revenue and cash flows are affected by economic factors. A summary of our revenue by product type for the nine months ended April 30, 2022 and 2021 is as follows: Summary of Revenue by Product April 30, 2022 2021 PURE Hard Surface $ 1,158,000 $ 2,815,000 SILVÉRION 251,000 26,000 Total $ 1,409,000 $ 2,841,000 A summary of our revenue by product type for the three months ended April 30, 2022 and 2021 is as follows: April 30, 2022 2021 PURE Hard Surface $ 352,000 $ 556,000 SILVÉRION 145,000 — Total $ 497,000 $ 556,000 Variable Consideration We record revenue from customers in an amount that reflects the transaction price we expect to be entitled to after transferring control of those goods or services. From time to time, we offer sales promotions on our products such as discounts. Variable consideration is estimated at contract inception only to the extent that it is probable that a significant reversal of revenue will not occur. |
Use of Estimates | Use of Estimates The preparation of consolidated financial statements in conformity with accounting principles generally accepted in the United States of America, or GAAP, requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements, and the disclosures made in the accompanying notes to the consolidated financial statements. Actual results could differ materially from those estimates. Those estimates and assumptions include estimates for reserves of uncollectible accounts, inventory obsolescence, depreciable lives of property and equipment, analysis of impairments of recorded long-term tangible and intangible assets, realization of deferred tax assets, accruals for potential liabilities and assumptions made in valuing stock instruments issued for services. |
Net Loss Per Share | Net Loss Per Share Basic net loss per common share is computed as net loss divided by the weighted average number of common shares outstanding for the period. Our diluted net loss per common share is the same as our basic net loss per common share because we incurred a net loss during each period presented, and the potentially dilutive securities from the assumed exercise of all outstanding stock options, restricted stock units, and warrants would have an anti-dilutive effect. As of April 30, 2022 and 2021, stock options, warrants and shares issuable under restricted stock unit awards of 7,391,625 10,358,765 Schedule of Anti-dilutive Securities Excluded from Computation of Earnings Per Share April 30, 2022 2021 Common stock options 6,179,125 8,018,500 Restricted stock units 1,212,500 2,012,500 Warrants — 327,765 Total 7,391,625 10,358,765 |
Inventory | Inventory Inventories are stated at the lower of cost or net realizable value, and net of a valuation allowance for potential excess or obsolete material. Cost is determined using the average cost method. Depreciation related to manufacturing is systematically allocated to inventory produced, and expensed through cost of goods sold at the time inventory is sold. Inventories consist of the following: Schedule of Inventories April 30, 2022 July 31, 2021 Raw materials $ 17,000 $ 17,000 Finished goods 284,000 315,000 Inventories $ 301,000 $ 332,000 |
Share-Based Compensation | Share-Based Compensation We periodically issue stock options and restricted stock awards to employees and non-employees in non-capital raising transactions for services and for financing costs. We account for such grants issued and vesting to employees based on ASC 718, whereby the value of the award is measured on the date of grant and recognized as compensation expense on the straight-line basis over the vesting period. We estimate the fair value of share-based payment awards at the date of grant using the Black-Scholes option valuation model. The Black-Scholes option valuation model requires the input of subjective assumptions, including price volatility of the underlying stock, risk-free interest rate, dividend yield, and expected life of the option. Share-based compensation expense is based on awards ultimately expected to vest, and therefore is reduced by expected forfeitures. |
Impairment of Long-Lived Assets | Impairment of Long-Lived Assets In accordance with GAAP, if indicators of impairment exist, we assess the recoverability of the affected long-lived assets by determining whether the carrying value of such assets can be recovered through undiscounted future operating cash flows. If impairment is indicated, we measure the amount of such impairment by comparing the carrying value of the asset to the fair value of the asset and we record the impairment as a reduction in the carrying value of the related asset and a charge to operating results. Estimating the undiscounted future cash flows associated with long-lived assets requires judgment, and assumptions could differ materially from actual results. During the three and nine months ended April 30, 2022 and 2021, no impairment of long-lived assets was indicated or recorded. |
