Review on Powerful True HEPA Air Purifier: Remove 99.98% Smokes/Dust/Pet Dander in 🌬️ Rooms up to 250~400ft² with Air Monitor & Digital Display During Night Light by Sung Shorunov

I bought a filter for my bedroom and found so many I wasn't sure which to choose so I just bought one and hoped for the best (if not, send it back if everything was so bad ) and found this one. That's quite enough, I can leave it on all night and it creates ambient noise that helps me sleep and also helps against dust. I can absolutely recommend this filter. I made a video so you can hear it. The video is high so low the whisper is low! Delivery was fast.
