Winix Replacement Filters for $59.99

Costco is offering the Winix Genuine Replacement Filter Z, 2-pack, for $59.99 with free shipping. This deal represents a $20 discount from the original price of $79.99, which is a significant savings of approximately 25%. The deal is valid through October 18, 2026, or while supplies last. These filters are compatible with the Winix C610 air purifier and offer up to two years of filtration with the True HEPA and activated carbon filters. This is a good opportunity to stock up on high-quality filters at a discounted price, especially given the typical retail price of these filters and the ongoing need for replacement filters for air purifiers.
