Affiliate Disclosure

FilterHound is 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.

What this means in plain English: When you click an Amazon link on this site and end up buying something, Amazon pays me a small commission. You pay the same price either way. That commission is what funds the time I spend keeping the data accurate, so if the site is useful and you want to support it, buying through one of these links is the simplest way to do that.

How affiliate links are marked: Every link from this site to Amazon includes my affiliate tag and the rel="sponsored" attribute, which is the standard signal to Google and other crawlers that the link is paid. Buttons labeled “View on Amazon,” “on Amazon,” or anything similar go through that program.

Editorial independence: No filter brand pays for inclusion on this site. The cross-reference data is compiled from public manufacturer catalogs and OEM documents, and the Amazon links point at whatever search returns the part number you're looking at. There's no commercial relationship between FilterHound and Pleatco, Unicel, Filbur, or any of the spa or pool brands listed.

Prices and availability: FilterHound doesn't display prices or stock levels because both change too often to keep accurate. Whatever Amazon shows when you click through is the real price.

Amazon trademark notice: Amazon, the Amazon logo, and Amazon Associates are trademarks of Amazon.com, Inc. or its affiliates. FilterHound is not affiliated with, endorsed by, or sponsored by Amazon.
