Reviews for ProCare humidifiers can be published in the reviews section of the products listing on the websites of major retailers such as Amazon and Walmart. Individual reviews can also be self published on social media sites such as YouTube.
To submit a review for a ProCare humidifier on Amazon, one must register for a free Amazon account and have successfully completed a paid transaction on the site for a physical or digital product, excluding free digital downloads, as of March 2015. The site does not require users to purchase the exact product to be reviewed, only one purchase to verify the user's identity through billing information. Once the account has been verified, the user can go to the Customer Reviews section of the product and add their review. The site allows users to include text and pictures in each review. Reviews can be rated for helpfulness as well as receive replies and comments from other users.
Video reviews published on YouTube can be created in whatever way the reviewer chooses, as the site does not place any guidelines on content other than prohibiting the use of copyrighted or illegal content. Videos uploaded to the site can be shared to different social media sites, including Twitter and Facebook, or embedded on a website.
