Ladies and Gentlemen:

We have acted as special Nevada counsel to EvoAir Holdings Inc., a Nevada corporation (the “Company”), in connection with the registration by the Company of up to 5,899,902 shares of its common stock, $0.001 par value per share (the “Common Stock”) including: (a) up to 3,750,000 shares of its Common Stock (the “Firm Shares”) on a firm commitment basis; (b) up to 562,500 shares of its Common Stock (the “Option Shares” and, collectively with the Firm Shares, the “Offered Shares”) in connection with an over-allotment option granted to the underwriters (the “Over-Allotment Option”); (c) up to 243,657 shares of its Common Stock (the “Representative’s Warrant Shares”) to be issued upon exercise of Common Stock Purchase Warrants (the “Representative’s Warrants”) granted to the underwriters in connection with the issuance of the Offered Shares ; and (d) up to 1,343,745 shares of its Common Stock (the “Selling Stockholder Shares”) to be sold by certain selling stockholders (collectively the “Selling Stockholders” and singularly, a “Selling Stockholder”) issued by the Company pursuant to certain Investment Exchange Agreements and a Share Exchange Agreement, as amended (the “Exchange Agreements”), between the Company and the Selling Stockholders.

The Offered Shares, the Over-Allotment Option, the Representative Warrants, and the Representative’s Warrant Shares are being offered, sold, and issued under the terms of an Underwriting Agreement (the “Underwriting Agreement”) by and between the Company and Network 1 Financial Securities, Inc., acting as the representatives of the several underwriters.
