It is good for the removal of pollen, house dust mites, mold spores, pet dander and other common indoor allergens. The maintenance for this unit is very easy.

Blueair 503 Air Purifiers Product Features

  • HEPASilent technology, exclusive to Blueair, combines mechanical filtration and electrostatic filtration for highly effective air cleaning that outperforms standard HEPA, capturing 99.97% of the tiniest particles at 0.1 micron.
  • Blueair technology allows extremely quiet operation. The low-density filters clean large volumes of air more quietly than any other air purifier. On the lowest setting, Blueair air purifiers are about as quiet as the average desktop computer.
  • Exclusive SurroundAir technology draws dirty air in from all sides and gently diffuses air through an area six times greater than the average air cleaner.
  • EnergyStar rated low energy consumption saves you money on your power bill. In fact, it costs about the same to clean the air in your home as it does to power a single light bulb.
  • Optional SmokeStop Filter has granulated activated carbon for enhanced removal of smoke, odors, and gases.
  • All Blueair products are environmentally aware and offer exceptional performance without polluting the environment. Blueair replaces standard filters (which can harm the environment) with safer, nontoxic polypropylene filters. In addition, Bluair air purifiers are coated with a special powder finish that produces no chemical off-gassing. The polypropylene filters also resist contamination from mold, bacteria, and viruses.
  • Unlike many electrostatic air cleaners, Blueair 503 air purifiers are safe for allergy and asthma patients because they release no ozone by-products.
  • Easy to Use and Maintain. Plug it in, select the speed setting, and forget it. To clean, simply wipe the steel exterior. When the filter needs to be replaced (every six months), just open the lid, lift the old filters out, and drop the new ones. No screws, no tools, and barely any time required.
  • The award-winning design is sleek and stylish, and the steel housing is durable and easy to clean.
  • Effective for room sizes up to 580 square feet

We live on a ranch in New Mexico and our owners don't like all the dust we all bring in the house after playing outside. So we told them about your Air Purifiers and they bought the Blue Air 503. It has done a great job and we get to stay in the living room now. Thank you for a great product.

Customer Q & A

Q1: Is this Blueair purifier now being made and/or assembled in China?
A: For the most part, yes. However, Blueair hasn't been entirely forthcoming with this information. To the best of my knowledge assembly no longer takes place here in the U.S. with the exception of a few models. For all units, the components are all made in China of foreign and domest components, and the filter media is made in the USA.

Blueair 503 HEPA Air Purifier Reviews

Blueair 503 Air Purifier

I could not wait to try out one of the new re-designed air purifiers from Blueair. The Blueair 503 completely lived up to my expectations. The first two fan speeds are virtually inaudible. The third fan speed, where I usually leave it while I sleep, is fairly quiet also - just a soothing hum in the background.

Being able to breathe fresh, clean air while I sleep makes such a difference in the quality of my rest. It is also nice to run the air purifier on high while I am cleaning. That way I know that all the dust and particles I am stirring up into the air are actually being removed and not just moved around the room.

What I like about the Blueair 503

It is attractive. The neutral off-white blends in seamlessly with my walls, and the sleek contemporary curves of the design give it a little more aesthetic appeal than most air purifiers. Actually, this design won Blueair one of the most prestigious design awards in Scandinavia - the Excellent Swedish Design award. I like that Blueair designs their products to look nice as well as perform to high standards.

It is quiet. The first two fan settings are so quiet I can barely hear them. The highest fan setting may be a little noisy for light sleepers, but it can work as a "white noise" for others. Compared to other air purifier models, the noise level is less on comparable speeds. The knob on the simply styled operation panel makes it easy to turn it from speed to speed, so it's no problem to switch it from higher to lower as you leave and enter the room, just like switching on the light.

It is economical. On the lowest fan speed, the Blueair 503 consumes about a little as 32 watts of power, far less than a standard light bulb. Even on the highest speed it is energy efficient, only consuming about 120 watts. You can run the air purifier all the time without worrying about the electric bill.

Maintenance is very simple. You simple open the top panel, pull the three filters and drop new ones in place every six months.

Unlike smaller Blueair air purifiers, the 503 pulls air in through the bottom and lower two sides while pushing clean air out through the top and upper two sides. This allows for better circulation of air throughout the room.

Being a larger model, the effective area is impressive. You can obtain five air exchanges per hour in a room as large as 22' x 22'.

The optional SmokeStop filter provides added protection against odor and smoke. This broadens the filtration range for those sensitive to tobacco smoke and strong odors.

What I do not like about the Blueair 503

Unlike other air purifiers brands, the 503 (like the other Blueair models) using no rubber or foam gaskets to ensure an airtight seal between the filters and the housing. The filters do fit snugly in all models, so this works to alleviate this concern.

In summary, as one of the most popular Blueair air purifiers, the 503 sets high filtration standards and delivers. With easy use and maintenance and a universal appeal, this air purifier fits well into nearly any home and decor. Low energy consumption and a 5 year warranty give added piece of mind while an optional SmokeStop filters broaden this model's appeal.
