Review on 🌬️ Wagner & Stern WA888: Ozone-Free Air Purifier with Powerful HEPA-13 Medical Grade Filter for Large Rooms. Eliminates Air Particles, Dust, Odors, Smoke, VOCs, Pollen, Pet Dander, and More. Black Finish. by Yalena Torres

Bought for covid patients and it really helped him breathe better. I chose this brand because the covid virus is 0.01 microns and most other cleaners are only good to within 0.3 microns. The Covid patient said he initially worked constantly but as air quality improved he worked about once an hour. The positive effects of ions on health and mood are well documented. "I can finally breathe," he said, wishing he had had this device from day one of his illness. The manufacturer provided information via email that is not included in the product description: The black w888 emits 0 bpm ozone and the white emits 50 bpm ozone. I don't know why there is such a difference as I received the dates in different emails. The WHO limit for ozone is 60 bpm and the FDA limit is 50 bpm making this device safe. Good product. Tried to order for our house today and they're sold out. Model 777 does not have an ionizer, but has an updated display. The air purifier was first used in the bedroom, then throughout the second floor of the colonial home. The device is designed to take up more space, so it is no longer used in the bedroom when the door is not open.
