is it really better than generic brands also claiming HEPA?

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

Mine just had the WiFi chip stop working. No more app connectivity!

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

Quote from DarnCrazy :
LifeSupplyUSA on eBay has been pretty solid when it comes to aftermarket filters. I've tried a few others but they were mostly no-name brands and they're no longer being sold. I also buy official Winix filters when they're on sale for cheaper than usual with credit card point deals. Ironically, I found the LifeSupplyUSA filters to actually be thicker and slighter better made and the official OEM filters.
Thanks. Just ordered 2 for $20 shipped. Worth a try
