Of the machine, very quiet

Works very well i am impressed

Works well very sensitive

Great product! Larger space to purify. Not having to change filters all the time is a plus.

Easy to use. Would buy again.

Works well. The air quality guage seems to be what I would think it is. Runs extremely quite

The air purifier works so Good I bought one for a friend who suffers from seasonal allergies.

Impressed, the air quality meter actually works.

Seems to work well. Air smells fresh.

My grandson was diagnosed with allergies. This has helped him so much.
