Review on Gree Home Air Purifiers with H13 True HEPA Filter for Smoke, Pet, Odor, Dust - Small Bedroom, Office, and Kitchen Air Purifier. Sensor-Equipped, Whisper-Quiet. by Dawn Adams

This Gree HEPA filter ran for about a month before they called me to replace the filter. However, I can't find a replacement filter. I bought two different brands and two different sizes of Revain filters. Both don't fit. So I'm trying to look for answers from QA. People also ask the same questions, but the seller said the filter won't be available until September. Now, at the end of September, I still can't find the filter. I wouldn't advise anyone to buy it until you buy replacement filters, although the product itself is good.
