Title: QuietCare for Medium to Medium/Large Rooms
Review: This is an excellent unit. Thorough air circulation, programmable, and I like the filter status indicator.The only problem I have with it is the noise. For this purifier to be true to its name with the low setting, use it in a room that is 20' x 20' or greater. When I am 10' or less from it, I can hear sharp and high-pitched sounds from the airflow. The big sound of air whooshing doesn't bother me, it's the higher stuff.I also have a large EnviraCaire HEPA unit that has comparable purification with a lower airflow note.To use this in a smaller room I run it 15-20 min. on med or high; then I can come back to the room and switch it off. Of course mileage will vary depending how easily allergens get back into the room. I'd consider buying another unit anytime.
