Review on 🌬️ Yabano Smoke Air Purifier for Home Bedroom | Covers 215 ft² | Ultra Quiet 20db | H13 True HEPA Filter 99.97% Effective in Removing Air Pollutants by Geoff Gunnmann

The sleep mode is very good and also quiet, you hardly hear it when sleeping. The blue light isn't very bright so it doesn't bother me while I'm sleeping. The time setting has four options: 2, 4 and 8 hours, if you don't select any of them it will take forever to turn off. I think this setting is really good, sometimes when I sleep I don't If you don't need to turn it off, it turns off by itself. I feel the air in the room has become fresher since I settled in the room, my husband is stuffy, I'm not sure if it's due to dry air due to the heater or an allergen in the room. Well, I have a humidifier and an air purifier, after a few days of using both his allergies are on the mend. I'm thinking of buying a few more and putting them in another room to keep the air in my house fresher and reduce dust and allergens.
