Review on 🌬️ ONE Products Neo Smart Air Purifier: Portable 2-in-1 UV & 3-Phase HEPA Air Purifier for Home, Office, Large Room - Kills 99.99% Germs, Bacteria, Allergens, Pollen, Smoke, Dust, Pet Dander (OSAP01) by Monica White

So far I have been very happy with this air purifier. I haven't had any issues with the app and my schedule has worked great so far. It works quietly at low frequencies, is barely noticeable at medium frequencies, and loud at high frequencies, which is to be expected. I know for a fact that the Auto Sense feature works because the other day I cleaned my oven, put in my greasy skillet and smoked the house for 30 minutes. The air purifier turned red and turned on by itself and I saw the smoke being drawn in. I was impressed. I rarely use ultraviolet light because 🤷‍♂️. You can't even see if it's working and I can't see a single bulb that could be replaced. Seems useless, but who knows. My main complaint is that the replacement filter is $50. You can't help but worry about not being able to get filters in the future. You can stock up on rough, but at this price point it's tough. I would recommend it though. If I encounter any problems I will update.
