Review on 🌬️ Olkheniif HEPA Air Purifier for Smart Home, Pets, Asthma, Smokers, 35m³-50m³ by Beth Martin

On top it is very powerful! It moves air at altitude. The air is blown out like a powerful fan, that's how strong it is. And can adjust the speed mode according to PM2.5 in real time to make the air fresher. Level 3 is a bit loud, but I can't even hear it on lower settings. The touch controls on the top are very responsive. The timing is good so it turns itself off if I forget to turn it off.
