A Conference  call is scheduled for Monday August,  16th,  11:00am Eastern time,
8:00am Pacific Time See dial in numbers below

VICTORIA,  BRITISH COLUMBIA, August 13, 2021 - FLEXIBLE SOLUTIONS INTERNATIONAL,
INC. (NYSE Amex:  FSI,  FRANKFURT:  FXT), is the developer and  manufacturer  of
biodegradable  polymers  for oil  extraction,  detergent  ingredients  and water
treatment as well as crop nutrient  availability  chemistry.  Flexible Solutions
also  manufactures  biodegradable  and  environmentally  safe  water and  energy
conservation technologies. Today the Company announces financial results for the
second quarter (Q2) ended June 30, 2021.

Mr. Daniel B. O'Brien,  CEO,  states,  "We are happy with the second quarter and
the first half of the year.  Raw material and shipping  costs may  constrain our
margins  in  the  second  half.  Regardless,  we  are  reasonably  confident  of
maintaining our recent growth in the second half of 2021 and through 2022."

o    Sales in the second  quarter  (Q2) were  $8,535,451,  compared  to sales of
     $7,709,607 in the  corresponding  period a year ago. The financials  show a
     Q2, 2021 net profit of  $1,176,761,  or $0.10 per share,  compared to a net
     profit of $1,132,867,  or $0.09 per share,  in Q2, 2020.

o    Basic weighted average shares used in computing  earnings per share amounts
     were 12,304,163 and 12,240,545 for Q2, 2021 and Q2, 2020 respectively.

o    Non-GAAP  operating cash flow: For the six months ending June 30, 2021, net
     income reflects $558,580 of non-cash charges (depreciation and stock option
     expenses),  PPP loan forgiveness,  as well as gain on investment,  interest
     expense,  interest  income,  and income  tax.  Net income  attributable  to
     non-controlling interests (minority interest) is removed from the cash flow
     calculation.  These are items not related to operating or current operating
     activities.  When these items are removed, the Company shows operating cash
     flow of $3,293,783,  or $0.27 per share.  This compares with operating cash
     flow of $3,044,425,  or $0.25 per share,  in the  corresponding 6 months of
     2020 (see the table that follows for details of these calculations).

The NanoChem  division  continues to be the dominant  source of revenue and cash
flow for the Company. New opportunities  continue to unfold in detergent,  water
treatment,  oil field  extraction and agricultural use to further increase sales
in this division.

Notes:  certain  items not  related to  "operations"  of the  Company  have been
excluded from net income as follows.

a) Non-GAAP -::  Flexible  Solutions  International  purchased 65% of ENP in 4th
quarter,  2018 (October 2018).  Therefore Operating Cash Flow is adjusted by the
net income or loss of the non-controlling interest in ENP (2021 = $454,933, 2020
= $199,093).

b) Non-GAAP - amounts exclude certain cash and non-cash items:  depreciation and
stock compensation expense (2021 = $558,580, 2020 = $348,191),  interest expense
(2021 = $113,329,  2020 = $156,075),  interest  income  (2021 = $32,445,  2020 =
$12,614),  gain on  investment  (2021 =  $399,236,  2020 =  $539,417),  PPP loan
forgiveness (2021 = $537,960,  2020 = N/A), write down of inventory (2021 = N/A,
2020 = N/A),  deferred income tax recovery (2021 = N/A, 2020 = N/A),  Income tax
(2021  =  $964,183,   2020  =  $694,648),   and  Net  income   attributable   to
non-controlling interests. See the financial statements for all adjustments.

c) The revenue and gain from the 50%  investment  in the  private  Florida  LLC,
announced in January 2019,  is not treated as revenue or profit from  operations
by Flexible  Solutions  given the Company  only  purchased  50% of the LLC.  The
profit is treated as  investment  income and  therefore  occurs below  Operating
income  in the  Statement  of  Operations.  As a  result,  the  gains  from  all
investments, including that of the Florida LLC, are removed from the calculation
to arrive at Operating Cash Flow.

d) Non-GAAP - amounts represent depreciation and stock compensation expense.
