I'm considering to buy an IQAir and I also buy their arguments. But I was surprised when I saw The Wirecutter review: http://thesweethome.com/reviews/best-air-purifier/ http://thesweethome.com/reviews/best-air-purifier/ Korean machines seemed to perform as well as IQAir and BlueAir, and they are quite cheaper (and use more efficient engines). Any comments?

I've owned a bunch of air filters but I like the IQAir ones the best. IQAir machines are built around a very heavy-duty prefilter that traps all the hair, dust, and large particles (maybe pollen-size?). The HEPA filter thus only gets a stream of tiny particles, so it lasts quite a while. Other models I've used (Plasmacluster, Rabbitair) do fine with brand-new filters but quickly accumulate dust that you have to vacuum out, and even then, the HEPA filter is probably already ruined. They also aren't sealed as well, so you don't get to hold up your particle counter to the exhaust and see a nice "0". (But the particle count in the room does decrease versus not running them, so they do do something.) The IQAir machines don't need any maintenance other than buying new filters when it tells you to. If you are trying to save money, don't buy IQAir. I try to evaluate effectiveness qualitatively and quantitatively. When I first got an air filter for my bedroom, I noticed that suddenly I didn't feel like coughing all night long. When I got the IQAir for my bedroom, I woke up the next morning with a sore throat because the back of my throat was totally dry. My chronic post-nasal drip was gone. It could have been my imagination, so I bought a laser particle counter to measure the particle count in my room. It was 0. (And it's counting the sub-micron particles.) (There are some caveats. Moving around in bed is particle city, so you're not breathing 100%-fresh air all night. But the filters take care of things very quickly, and I run them on a high setting, and they're close to my bed. You'll need earplugs. Air filters on the "silent" setting do approximately nothing. This was not a problem for me because I've slept with earplugs for years due to annoying cats. Now I can't sleep without them, the sound of sheets moving against each other is annoying :)

  Really glad you like our product. I will admit it is pretty expensive, but as you've said, your particle count will get to almost 98% of less than what was originally lurking in your rooms. That is nowhere near what other air purifiers can do. When I first joined the company, I was told not to put it on full blast the first night otherwise your mouth will become dry. It still blows my mind that people experience that. I keep mine on throughout the night as well, but I have definitely noticed the sound doesn't have the humming sound as opposed to other air purifiers. It is a much quieter, fan like sound.

    Yeah, it's definitely not as annoying as other models I've tried. The RabbitAir one has a really annoying high-frequency component that prevents me from running it on its highest setting even with earplugs. Now I just need to buy a house so I can get a Perfect 16 installation and move the noisemaking equipment out of my bedroom.
