Review on Vremi Premium HEPA Air Purifier for Large Spaces - Eliminates 99.97% of Airborne Contaminants with H13, Activated Carbon, and 3-Stage Filtration - Enjoy Fresh Air Every Day by Bethany Baker

I bought this air purifier for my pottery workshop to try and get rid of the clay dust that is always there. The Hepa H13 filtration was key and the cost of replacement filters was really reasonable so I decided to give it a try. It has been working on "Auto Sense" for two days now and I am very satisfied. I usually wipe the floor with a damp mop to keep it dust free, but I decided to see what would happen if I sweep it with a broom. Within seconds of sweeping a small area, the light changed from blue to orange to red and the fan kicked on at high speed. So he felt the dust in the air and worked harder to filter it out. After a few minutes, the light turned blue again and the fan began to whisper softly. Couldn't be happier. Now I want one for my home!
