Review on PuriDoc Air Purifier for Home: H13 True HEPA Filter, Silent Operation, 99.97% Pet Pollen Dander Smoke Odor Removal - Ozone Free, Bedroom Living Room White (1 Pack) by Lisa Smith

I had severe allergies and was addicted to nasal spray for years and had to use it every night before bed. After using this cleanser for a month I didn't need a spray to get through the night for the first time in years, my sinuses were cleared within weeks and it's amazing. Perfect size, I wouldn't go taller or shorter in the bedroom. I use it 24/7 and the quiet mode is great for sleeping.
