Review on 🌬️ Flintar C545 True HEPA Replacement Filter S for Winix C545 Air Purifier - Replaces Winix S Filter 1712-0096-00: H13 Grade HEPA Filter + Activated Carbon Filters (1-Set) by Danielle Smith

I bought Costco's OEM filters but decided to try these filters. I was initially skeptical after reading some of the loose fit filter reviews. Having received and installed the filters myself I would say I would definitely purchase these filters over OEM. They are perfect and fit exactly. Even tighter fit than original Costco kits. The HEPA filter is really tight on the frame. The OEM filter fell off with pretty much no effort to remove right after removing the pre-filter and carbon filter.
