the aftermarket c545 filters are on sale now, although they are more expensive than what I paid for in December: https://www.amazon.com/gp/aw/d/B0D95X1VPL

Found the original filter S at Costco on sale. A 2 pack for 60 bucks. Always the best deal I have found for my units: https://www.costco.com/p/-/winix-...4000225508

With the sale they are having on that product, I wouldn't even risk getting an after market: https://www.amazon.com/Winix-Comp...T1OR8Tried the aftermarket before and it wasn't washable and had to buy it way faster than 1 year. Ended up being more expensive than just buying the original for Winix.
