“I noticed a difference the first day and so did my patients. Now when the sun shines in my windows I no longer see dust particles floating around in the air.”

“Performs perfectly, and is very quiet. When I cook indoors or step back inside after grilling, this appliance kicks into high speed and filters the odors and settles back to low speed.”
Rosie J
“This elegant, but powerful unit constantly sniffs the air and quickly filters out the air when we’re cooking salmon or steak. It keeps the air fresh and clean”
