It's larger than I expected but that's my fault for not paying attention to the measurements. I keep it on a small typing table in my office, about 9 inches from the wall, and I set it to run with the ionizer on for 8 hours when I get to work in the morning so it shuts off automatically at the end of the day. It's so quiet, I'm barely aware it's there until some invisible floating particles cause the indicator to go from blue to purple (or red) and the fan speeds up for a minute or so until the air is clean again. Fast and efficient!

I purchased one Conway AP-1512HH to see how it preformed. I have been very pleased. The machine is well made and filters the air well. The sound level on low can barely be heard and the sound on medium is OK. The sound on high is fairly loud. The power consumption is extremely low - measured via my Kil A Watt type meter - 3.5 watts on low, 8.6 watts on medium (with ionizer on), and 58 watts on high w/o ionizer. I liked the machine so much that I purchased another two of them for other rooms in the house. I leave them running on low or medium 24/7 since they use so little electricity. Also, the filter replacements (aftermarket with good reviews) are affordable (~$25/yr). Are there slightly better air purifiers - Yes, but they cost 4X as much as this unit. I would recommend this air purifier.Read full review

Got this for my Freshman who's dorm is on a busy city street. Lots of smog. Roommate has tons of allergies. We did a test run over the holidays. Set it to "sensitive" mode (there are three modes). Running it on auto sound is not noticeable. Blue light indicates air is good. We shook off a duster in front of it and the sensor light immediately turned purple and fan kicked on. A minute later it went back to blue. This is a super way to auto clean one room's air. I don't believe there is a way to turn off the sensor light. The blue glow is noticeable in a dark room. Other than that set it and forget it. Until it's time to change the filter after 6 months+ (12 mos recommended, but a warning light alerts when its time). Cheapest filters I found were on amazon.

Very nice. We also have an Aerus Guardian Angel purifier. This Coway is MUCH more quiet. Really like the air sensor which modulates the fan speed. The visual air quality indicator is also pretty neat. The best thing is it's a true HEPA purifier that doesn't produce a bunch of white noise.

nice air purifier, silent on low speed, still very quiet on higher speed, I run it all night and I sleep better, no stuffy nose from allergies like before. Status light is cool feature, it is blue for clear air, but turns purple for moderate dust, and red for very dusty air, so you can see it working. Very happy with it!
