Pick a code below and click it — we copy it for you and send you to WaterFilters.net. Paste it into the promo box at checkout before you pay.
Can I use a code and still earn cash back?
Yes, that is the point of this page. Only use codes listed here though — a code from somewhere else can overwrite our tracking and cancel your cash back.
When does my WaterFilters.net cash back arrive?
It shows in your account as pending within a few days, then becomes payable once WaterFilters.net's return window closes.
A code did not work. What now?
Codes expire, and some are limited to new customers or certain products. Try the next one down — they are ordered by how well they are working right now.
