Save $10 on Filtrete Air Filters!

Costco is offering a $10 manufacturer’s discount on the Filtrete Air Filter 1”, MPR 2500 MERV 14 4-pack, with the promotion running from now until June 7, 2026. The current price is $42, and this deal provides a significant savings on high-performance allergen and virus filters.

These filters feature Filtrete™ 3-in-1 Technology, helping capture microparticles like pet dander, smoke, bacteria, as well as larger particles such as pollen and household dust. They are also certified as asthma and allergy-friendly, making them an excellent choice for health-conscious consumers.

The deal has a limited purchase cap of 10 per member and offers a good opportunity for ongoing filter needs, especially given the filter’s high ratings and quality. Costco's pricing at $42 combined with the $10 discount makes them an attractive option compared to other retailers, especially considering the prominence of the MERV 14 rating and MPR 2500, which are premium specifications for air filtration.

Overall, this discount is a substantial deal for high-grade air filters, and given the limited-time offer, it deserves to be flagged for alerting users interested in air quality or allergen reduction solutions.
