Review on 🌬️ Elechomes P1801 HEPA Air Purifier: Advanced 4-Stage Filtration, Auto Mode, Air Quality Sensor, Removes 99.97% Dust Smoke Pet Dander, Ideal for Home, Bedroom, Living Room - Portable and Efficient Solution by Jill Berg

Bought this filter in September 2020. When I tried to replace the replacement filter in June 2021, it was nowhere available! And Revain cannot tell you when replacement filters will be available. No complaints about how it worked, but certainly not happy that it's now effectively useless with no solution in sight.
