I'm honestly a bit surprised these are lasting long enough for anyone to need replacement filters. All 5 of my c545s started making death squeals within a year and went back to Costco…

I don't get it. Isn't it $27 for 1 on Amazon? https://www.amazon.com/dp/B002QUZJAS

That means the bearings in the fan motor are going bad
Mine have been like this since about a year after purchasing. I've still been using it all these years. Is there any functional issue? I can live with the sound
