           File No. 333-231829

Dear Mr. Erickson:

       We have reviewed your July 9, 2019 response to our comment letter and
have the
following comments. In some of our comments, we may ask you to provide us with
information
so we may better understand your disclosure.

       Please respond to this letter by amending your registration statement
and providing the
requested information. If you do not believe our comments apply to your facts
and
circumstances or do not believe an amendment is appropriate, please tell us why
in your
response.

       After reviewing any amendment to your registration statement and the
information you
provide in response to these comments, we may have additional comments. Unless
we note
otherwise, our references to prior comments are to comments in our June 25,
2019 letter.

Response letter dated July 9, 2019

Fee table, page i

1.     We note your response to prior comment 2 and Exhibit A to your response.
Given that it
       appears that you are seeking to register the resale of common shares,
not the exercise of
       warrants or the conversion of the preferred stock, it is unclear why
your reliance on Rule
       457(g) is appropriate. Please clarify or revise as appropriate. Also:
         show us how you calculated the "Proposed Maximum Aggregate Offering
Price" and
          "Amount of Registration Fee" for the shares of common stock
underlying the interest
          on the convertible notes; and

             tell us how you determined the number of shares issuable upon
exercise of the Series F
             Preferred Warrants, given your disclosure on pages 32-33 regarding
the number of
             warrants issued.
Selling Security Holders, page 30

2.       Please expand your response to the second bullet point of prior
comment 3 to address the
         common stock issuable upon exercise of the Series F Preferred
Warrants.
3.       Please disclose the substance of your response to the fourth bullet
point of prior comment
         3. Also disclose, if true, that all securities offered by an affiliate
of a broker-dealer were
         purchased by the seller in the ordinary course of business, and, at
the time of the purchase
         of the securities to be resold, the seller had no agreements or
understandings, directly or
         indirectly, with any person to distribute the securities.
4.       We note your response to the eighth bullet point of prior comment 3.
Please ensure that
         the number of shares registered for sale in the fee table is
consistent with the shares listed
         in "Selling Security Holders." We note in this regard that the "Grand
Total" in column (c)
         does not appear to reconcile to the proposed revisions to the fee
table.
5.       We note from your response to the tenth bullet point of prior comment
3 that the company
         is not aware of any short positions held by any of the selling stock
holders. Please clarify
         whether that response was based on information obtained from the
selling stockholders.
6.       Please expand your response to prior comment 3 to provide us your
analysis supporting
         your conclusion regarding why your agreements with Boustead Securities
need not be
         filed as exhibits to your registration statement.
7.       From your response to prior comment 3, it appears that you do not
intend to use cash to
         repay the principal and interest under the note. It therefore remains
unclear whether in
         substance the transaction is a primary offering of your common stock.
Please expand your
         response, citing all authority on which you rely, or revise your
registration statement as
         appropriate.
8.     Please include in your response to prior comment 3 information regarding
prior securities
       transactions between the issuer (or any of its predecessors) and the
selling stockholders,
       any affiliates of the selling stockholders, or any person with whom any
selling stockholder
       has a contractual relationship regarding the transaction (or any
predecessors of those
       persons). Include the date of each transaction and the consideration
paid, and whether the
       securities have since been sold by the selling stockholder. Also clearly
identify in your
FirstName LastNameRonald P. Erickson registered securities for resale by the
selling security
       response when you have previously
Comapany NameKnow Labs, Inc.
       holders named in this registration statement, including whether and when
those securities
       have been sold.

9.       Please disclose (1) the price of your common stock on the dates that
the selling security
         holders acquired the offered common stock or the securities by which
they can acquire the
         offered common stock, and (2) the cash fee paid to the selling
security holder. Also:

             clarify how the conversion and exercise price adjustments will be
made for events
             requiring adjustments; and
             in the context of your disclosure regarding the Series D
Convertible Preferred
             Stock, disclose the stated value of that preferred stock.
