 Very pleased with the resultsOct 01, 2010
By Go Penguins
Wow. I am shocked to say the results were within 2 hours. Current apartment has black mold. Asthma has been horrible wherever I go.. always using an inhaler and constant sneezing, head congestion, chest congestion, not sleeping, missing work, etc. I do have allergies and sinus issues, but... they were controllable and I was rarely using my inhaler until they started ripping the black mold out of the wall / drywall. I bought this to help until I move in a few weeks. I changed my mind about putting it in the current apartment (didn't want the mold in the new air filter). So I took it to the new place. Remember, no matter where I went, my asthma has been an issue (work, shopping, family). I cranked the Blueair on Max. After 2 hours I sat on the floor to unpack a few boxes. I was noticing my breathing was deeper, not shallow from my upper chest, but from my diaphram. I laid on the floor. I could breathe! It was effortless and not a struggle. No wonder I have been so exhausted.. it had become a struggle to breathe regardless where I was. I worked in the new apt for about 6 hrs. NEVER used my inhaler. Went back to current apt... used the inhaler within 2 hours. ?!?! Until I could FINALLY breathe normally, I didn't realize how this had crept up and was getting worse. Honestly I could cry. Because of the Blueair, I will be suing my apartment building. $400 is nothing to sneeze at (!), and money is very tight, but it is so worth feeling better.
It is loud on max speed, but it was not annoying to me. On low speed, I could barely hear it. So I'm sure the sound isn't anything to keep me up at night.

Incredibly QuietOct 06, 2010
By Spike
First off I am amazed at how quiet it is. It is only loud on the highest setting, and even that is bearable, it is similar to running a box fan on high. However, as soon as you switch to the next setting down, it is much quieter, about the sound of a low fan or in some cases the sound AC makes when running - I think this is a great setting still good air flow but much too quiet to disturb anyone. The next two settings down, I literally CANNOT HEAR AT ALL! Specifically the next one down, I can only hear if I put my ear up close to it, and the lowest setting, "HEPA silent" I had to feel the airflow to be sure it was running. This is great, compared to my other air purifier (Honeywell 50250N) it is much quieter - it's second highest speed setting is as or more quiet than the lowest setting on my Honeywell, and it is also designed to cover a larger area and has a special filter option for filtering smoke.
I've only just bought it and ran it one day, so I can't say yet for sure how well it will filter the air, but so far it seems to be doing a good job, the air smells fresher and I haven't noticed the occasional smoke order - I'll be able to tell better when it gets colder and the people in the apartment below me and around me smoke more indoors. The reason I got it was particularly to deal with the chain-smoking idiots who live below and around me - whenever it gets cold they pretty much smoke constantly inside their apartment, and all the smoke seems to get filtered by the apartment building design into my apartment. I may update this review after I've used the purifier for a few months.

The only effective remedy for my allergiesFeb 23, 2012
By Rudy
For years I suffered from severe allergies to dust, pollen, all the usual airborne allergens. Springtime was the worst. I bought the Blueair 503 on the strength of other Amazon reviews and am amazed by how well it works. After just a couple of days, no more sneezing, sniffling, coughing! As other reviews have pointed out, it is noisy at the highest speed, but I've found no need to use that setting. By day, I keep it on the medium or next to lowest setting (very quiet) and when I sleep I put it on the lowest setting, which is super-quiet and still effective. Word of advice: Launder all of your bedding when you begin using the Blueair so you're not breathing in dust particles that may be hiding in sheets, blankets, etc. Word of warning: For the first few days, the Blueair has a weird, but not unpleasant, "new car" smell. That dissipates quickly. Highly recommend!

Outstand ROOM Filtration!Dec 01, 2011
By D Willard
Some have stated that this helps keep the air in the entire house cleaner and while that may be the case under ideal conditions (windows closed during the summer, ESPECIALLY in our hot, arid and dusty Southern California summers), they are really intended for large rooms. Regardless, I do agree, these are outstanding air "scrubbers."
For those that may have experienced a less than desirable outcome, when we clean the exterior grids (every one to two weeks) we notice a massive accumulation of dust (from one room, 25'x35' with windows closed!). When we "reverse" blow air through the filters every month or two (due to the massive amount of dust being trapped by the filters, AGAIN, with our windows closed!), we also notice even more huge volumes of dust blown from the 3 filters and that is AFTER cleaning the exterior grids!
Pros: outstanding large ROOM filtration systems; ROI on replacement filters not anymore expensive considering the longer life cycle of the Blue Air filters over the typical HEPA filters (6 months/Blue Air vs. 3 months/Typical).
Cons: Windows, patio doors, etc SHOULD be kept closed, ESPECIALLY during our arid, dusty So Cal summers (but then, that would be the same with even a WHOLE house filtration system, otherwise, the only thing being accomplished is the outside air being cleaned!)

 Blueair 503 HepaSilent Air Purification SystemFeb 24, 2012
By Rick
I have a problem with allergies and the two cats I have don't help. Ever since I've been using the Blueair 503 at night I wake up fresh and ready to go in the morning now. Before my sinuses would be all clogged up and I would be coughing at night. Now I don't have that problem anymore. Thanks Blueair
As for the noise problem some people complained about it's really no big problem. Turn the fan down to the one of the first two settings and you can sleep like a baby thru the night.
