Save $10 on Filtrete Air Filters!

Costco is offering the Filtrete Air Filter 5”, MPR 1550, MERV 12, Ultra Allergen, Bacteria, and Virus Deep Pleat Filter in a 2-pack for just $36.99.

This deal includes a $10 manufacturer’s savings valid from May 11 to June 7, 2026, while supplies last. The filter is highly rated with a Microparticle Resistance (MPR) of 1550 and a MERV 12 rating, capable of capturing microscopic particles such as smoke, bacteria, viruses, dust, and pollen.

Compared to typical prices, this represents an attractive saving, especially given the product's certification as asthma & allergy friendly and its advanced 3-in-1 trapping technology.

You can purchase up to 10 packs per member, making it a great deal for households needing multiple filters. Overall, this is a solid value considering the discount, high filtration rating, and Costco’s reputation for quality and bulk savings.
