Review on 🌬️ Efficient HEPA Air Purifiers for Home Bedroom | Quiet, Clean & Powerful | Removes PM2.5, Pollen, Smoke, Odor, Dust, Pet Dander | Electric Cord Powered by David Thornton

I am currently using 2 of these in my 10x12ft bedroom. This is the only room in the house where I smoke. I smoke at my computer desk. One fits next to me and the other is about two meters away from me. About an hour after smoking, the purity of the air does not change. I got the oils and they help a little but not in the way I thought. I recommend getting a better system since I've already invested $100.
