$10 Off Filtrete Air Filter 2-Pack

Costco has the Filtrete Air Filter 4”, MPR 1550 MERV 12, 2-pack for $33.99. The $10 manufacturer’s savings is valid from 9/21/26 through 10/18/26, while supplies last.

This filter features a 1550 MPR and MERV 12 rating, designed with Filtrete™ 3-in-1 Technology to help capture microparticles like pet dander, smoke, and smog, as well as larger particles like lint, pollen, and household dust. It is certified as asthma and allergy-friendly.

While the deal offers a notable dollar discount, the price of $33.99 for a 2-pack is consistent with typical retail prices at Costco, and the savings amount is relatively modest. It might be worth watching if similar deals become available during peak sale periods, but currently this is an average deal for these filters.
