Bests & Worsts Reviews from Amazon

I’ve had this air purifier for over a year and have replaced the filters about once every 2-3 months. However, when I received the filter I ordered a week or two ago, I was surprised that the black carbon layer had been changed. It’s similar to felt. Because of this new change, my air purifier is working OVERTIME. It’s insanely loud, and has to be vacuumed daily (which isn’t very helpful, whereas the original one was easy to clean and significantly decreased the loudness). Vacuuming it daily doesn’t help. The new carbon layer is thick and clogs almost immediately. I’m really disappointed with this product. The original one was great, why fix what isn’t broken? This new filter is really testing the limits of my (very expensive) air purifier.
