Short version: WhatSizeIsMyFilter.com earns commissions when you buy products through our links. You don't pay more. We still tell you what we honestly think.
We make money through affiliate programs. When you click a link on our site and buy something, we may earn a small commission at no additional cost to you. We only recommend products we believe are genuinely useful, and commissions do not change our editorial opinions.
The Full Disclosure
In accordance with the U.S. Federal Trade Commission's 16 CFR Part 255 ("Guides Concerning the Use of Endorsements and Testimonials in Advertising"), WhatSizeIsMyFilter.com discloses that it participates in several affiliate marketing programs. When you click certain links on our site and make a qualifying purchase, we may receive a commission from the retailer.
Programs We Participate In
WhatSizeIsMyFilter.com is a participant in, or partner with, the following affiliate programs and networks:
- Amazon Associates Program — We are a participant in the Amazon Services LLC Associates Program, an affiliate advertising program designed to provide a means for sites to earn advertising fees by advertising and linking to Amazon.com.
- FilterBuy Affiliate Program — We partner with FilterBuy for direct-to-consumer air filter sales.
- Discount Filters (via ShareASale)
- Second Nature Filters — a filter subscription service
- Impact.com, CJ Affiliate (Commission Junction), and Awin — general-purpose affiliate networks that connect us with additional retailers
We may add or remove affiliate programs at any time without updating this list. Any affiliate relationship on this site is governed by the same commitment to honest editorial.
How Affiliate Links Work
When you click a link labeled "sponsored" or similar on this site, you are directed to the retailer's website. If you make a qualifying purchase within the retailer's tracking window (typically 24 hours to 30 days depending on the program), the retailer attributes the sale to us and pays us a small commission — usually a percentage of the purchase price.
You pay nothing extra. The price you pay is identical whether you click our link or go to the retailer directly. Commissions come from the retailer's marketing budget, not from you.
Our Editorial Commitment
Affiliate income keeps this site running, but it does not influence our content. Specifically:
- We recommend products based on research and genuine usefulness, not commission rates.
- We do not accept payment for positive reviews. Brands cannot pay to be featured or recommended.
- We will tell you when a product has downsides, even if that product is a revenue source for us.
- We may compare products across retailers (Amazon, FilterBuy, manufacturer direct) and recommend whichever offers the best value, even if the commission differs.
Advertising (Google AdSense)
In addition to affiliate links, we may display advertisements through Google AdSense and similar programs. Advertisements are served by third parties and are not editorial endorsements. Ad content is based on your browsing behavior and is not controlled by us. See our Privacy Policy and Cookie Policy for more on how advertising cookies work.

Amazon-Specific Statement
As an Amazon Associate, WhatSizeIsMyFilter.com earns from qualifying purchases. This statement is required by the Amazon Services LLC Associates Program Operating Agreement and is repeated on each page containing Amazon affiliate links.
Your Choice
You are never obligated to use our affiliate links. If you prefer not to, you can search for any product we recommend directly on your preferred retailer's site. We appreciate it when readers choose to support the site through our links, but we'd rather you find the right product for your needs either way.
