Not going to lie. I set this thing up, tested the water and it has a small percent of chlorine, which is optimal.
I set the sensor to high sensitivitiy.
As I was reading the instructions, I farted a real good one. The light went from a quiet song, with a green lit led to a louder wooshing, red led, and water mist spraying from the machine.
I knew I found my true love.
Bought this a month ago, my room smells great. Had problems with smells due to myself, outdoor pollens, allergies, etc. I love this thing and I'm glad I bought it.
It sure beats my $400 ionic honeywell machine that did absolutely nothing except act as a really tall and heavy paper weight.
