Custom Filters Direct — the questions people ask
How do I use a Custom Filters Direct promo code?
Pick a code below and click it — we copy it for you and send you to Custom Filters Direct. Paste it into the promo box at checkout before you pay.
Are these Custom Filters Direct codes tested?
Every code on this page is checked by hand before it goes live, and the ones that stop working are pulled.
What if none of the codes work?
Try a deal instead — those need no code at all. Codes are ordered by how well they are working right now, so start at the top.
How often is this page updated?
Daily. New Custom Filters Direct codes go up as soon as we can test them, and expired ones come down.
