Review on RENPHO WiFi Air Purifier - H13 True HEPA Filter for Large Rooms up to 1440 Ft², Allergen & Pet Dander Remover, Eliminates Mold, Pollen, Dust, Odor, Quiet Sleep Mode, Ozone Free - Black by Sirryan Bloodworth

I wake up when my dogs breathing pattern changes during the night. So it's pretty hard to sleep when there's too much background noise. This air purifier always runs at a constant noise level and does a great job of picking up dust. I love the timer feature on your phone because I'm definitely the kind of person who runs out of the house and forgets to turn everything off. I also really like the AQ feature and the way it tells you what level your filter is at so you can track its usage over time instead of waiting for it to change noticeably or audibly deteriorated. I would definitely buy again if needed!
