Water Filter Deal - Save $35!

Costco is offering a $35 manufacturer’s savings on the PureSource Ultra II or Purepour PWF-1 water and ice refrigerator filters, valid from April 18 to April 19, 2026. This discount brings the current price to $100 for a 3-pack, with the deal available while supplies last. The filters are NSF 42, 53 & 401 Certified, capable of filtering out up to 99% of contaminants, and designed for easy push-and-twist or push-to-lock installation that lasts up to 6 months each.

This deal offers a significant savings on high-quality refrigerator filters, especially for Costco members who can purchase up to 5 sets. Given that the retail price is around $100 for the set and the manufacturer offers $35 off, this promotion represents a good value. The quick install features and certifications add to the appeal.

While this isn’t a historic price low, it’s a solid discount on a popular product, and the limited-time nature makes it worth considering for those in need of filters now or soon.
