Affiliate disclosure

As an Amazon Associate, FilterByZip earns from qualifying purchases.

When you follow a "shop replacement filters" link from this site and buy something on Amazon, we may receive a small commission. It costs you nothing extra and doesn't change the price you pay.

This is how the site pays for itself — the schedule estimates and email reminders are free, with no account and no ads.

Two things the affiliate relationship never changes:

• Your schedule. The replacement interval is computed from regional water-hardness data and your household size. Nothing about it is tuned to sell more filters.
• The links themselves. Buy links are plain Amazon search results for your fridge brand's filter — we don't push specific products or sponsored listings.
