Winix Filter Pack for $59.99

Costco has the Winix replacement filter pack for $59.99, a pack of two filters designed for C535 and C909 air purifiers.

This deal saves $20 off the manufacturer's suggested price, with the savings valid from September 1 through September 30, 2026, while supplies last. The deal is limited to 5 per member.

These filters feature True-HEPA filtration, capturing up to 99.97% of particles as small as 0.3 microns, which ensures high-quality air purification.

The current price is consistent with typical retail pricing, but the discount, combined with free shipping and the limited promotional period, makes this a good opportunity for those needing filters for these models.
