Review on 🌬️ MSA3 Air Purifier: True HEPA Filter, 100% Ozone Free, Removes 99.97% Allergens, Dust, Odor, Smoke, Pollen - Ideal for Large Rooms, Bedrooms, Smokers, Pets, Allergies by Mary Hall

I am so happy with this purchase. It's quiet and seems to be doing a good job. Even though I've only had it a week. The first day I turned it on it smelled weird. I thought it might be because it wasn't enabled before. I thought I might have to return it but when I turned it on the next morning the smell was gone and it just smells like fresh air. One of the main reasons I chose this product is that it was ozone free with a Hepa filter. The front panel controls are easy to read and easy to use. I haven't used it in sleep mode so I don't know how it works. I use it for the rest of the house. You can turn off all displays except the one that says it's on. I would recommend this air purifier to anyone looking for a quality air purifier.
