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...

See Products Related To Blueair 503 HepaSilent Air-Purification System: Blueair Perfect for larger rooms, up to 580 square feet, the Blueair 503 air purifier uses superior HEPASilent technology to capture 99.97% of harmful particles such as dust, pollen, and bacteria, down to 0.1 microns in size. Uses both electrostatic and mechanical filtration to deliver clean air efficiently. The Blueair 503 is independently tested and certified by the Association of Home Appliance Manufacturers (AHAM) for a Clean Air Delivery Rate (CADR) of 375 cubic feet per minute for smoke, dust, and pollen, at five air changes an hour. Utilizing SurroundAirTM technology, the 503 takes in air from three sides, releasing clean air from the top and sides, reducing draft and maximizing clean air delivery. Easily change filters from the top of the unit and keep track of filter changes with the included magnetic filter timer. A trusted air purifier, the 503 was tested alongside 22 other air purifiers by The Consumer Rights Protection Commission of Shanghai and rated the best in performance for removal of fine particles (PM2.5) and formaldehyde. Intended for use with standard US outlet: 120VAC, 60Hz Good unit, but with a long term design flaw. Straight out of the box, this unit did everything we had hoped! It drastically cut down on dust and pollen and left the house smelling fresh and clean. I also love that the wheels make it possible to easily place the unit where it is needed most - next to the kitchen when cooking something smelly, near the litter box at cleaning time, etc. We've used the unit consistently for about three years now. I still love it, but it seems there is a pretty obvious design flaw. The air intake occurs through wide grills along the bottom of the machine. Air then passes up, through a fan, and is filtered as it is pushed out through the filters on the top and side. This is different from most air "cleaners", which typically pull air in through a filter. The problem with this Blueair design is that the incoming dust collects, over time, on all of the internal components. After several years of use, the wiring and fan are caked with thick dust and pet hair. The...
