Summary: I purchased the unit for a bedroom to help ease allergy issues. The unit works good in my 10x17 room on low and it just tolerable when falling asleep. When I move the unit a larger room and bump up the speed, the noise increase goes up quickly.
Pros: This unit is able to circulate and clean a decent sized room at the lowest setting.
Cons: The noise level above the lowest setting is higher than I expected.
Summary: I bought this product primarily for dust control. Living out on a farm, dust/dirt is often brought in on boots, transfers to the hardwood floors and ends up scattered around on furnishings, especially in one particular bedroom.
Summary: I have one of these 50250 and the top rattles a lot, inside the motor housing area so can't fix it with a new filter. It was a gift so I did not have a waranty on it but in addition to the operation of the motor itself you can listen to the rattle that sounds like some cheap plastic part is loose...
Summary: Bought this to help with the smell of smoking family members. It did clean the air but has a very annoying drone sound to it. Even on its lowest setting. on high its, lets be fair, noisy to say the least. It does work extremely well
Pros: Cleans tobacco smell from the air.
Cons: Noisy, even at its lowest setting, still makes a fair amount of noise.
Summary: This thing is amazing! Living in a dorm the size of a walk-in closet with three other guys can get stuffy. That's where this air purifier comes in handy, especially when your roommates only do laundry every two weeks!
Not actually a Honeywell, no surprise it's not Honeywell quality

Summary: Terrible quality. Like so many others' complaints, the rubber used on the filter element outgases a terrible noxious odor. On one unit it went away after about 36 hours. On the other unit it took over 7 days to get to low enough levels of outgassing I could even stand to have it in the house.
Works way better than my previous HEPA-like filter

Summary: Works way better than my previous HEPA-like filter. This one has a true HEPA filter as well as prefilters. Once a month I remove the bottom and vacuum off the prefilter and it's good to go. I have 2 dogs, 3 cats, a bird, and hardwood floors.
Summary: 6 cats-should I go on? It helps reduce the dust of 10 litter boxes, but you WILL still have to dust(darn it). It's quiet and pulls in a lot of dust, hair, etc. It's really easy to clean filter. Had it for 6mos. Cleaned out once, but I have 2 of these in the house and 2 smaller units.
Summary: And a monster is exactly what I wanted; this thing moves a LOT of air. And it's noisy too, on max Turbo, where we leave it all day while we're both at work. At night we run it on Low and it's not overly objectionable; if you WANT to hear it you will, but for the most part, on Low, it's just...
