Very pleased with the results
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 exhaust ed.. 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.

Outstand ROOM Filtration!
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!)

Great Unit
By jeffer
I recently received my Model 503 unit. I am very happy so far.

It has four ON levels. I normally leave it on level 2 since the sound level is insignificant. I try to turn it up to level 4 for two or three hours every day. On the highest setting, the sound is noticeable, but it is a very smooth clean sound (moving air with no rattles, etc). During my first night or two, I ran it over-night on level four. The level 4 sound worked as white noise for me.

It has been in operation for about two weeks and I can already tell a difference. The dust is gone. I don't have asthma problems, but sometimes do get sinus issues when trying to sleep at night. This unit has improved my situation.

My unit came with a magnetic LCD remote that can be attached to the 503 unit, your refrigerator, or wherever. This device will show how many days are left before you need to change the filter.

*EDIT - My unit is now over a year old. It is still running fine and is as quiet as the first day I powered it up.
