Blueair Classic 503 Air Purifier I could not wait to try out one of the air purifiers from Blueair. I have consistently looked for an air purifier that balances filtration and dust removal with noise level, and with Blueair models billed specifically for this, I was very interested in trying one out.

After a week of using the Blueair 503, I can safely say that it completely lived up to my expectations. 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 and even in the amounts of visible dust in my bedroom. Here is a more of a "nuts and bolts" assessment of my time with the Blueair 503. What I like about the Blueair 503 It is quiet. The highest fan setting may be a little noisy for light sleepers, but it can work as a "white noise" for others. Whether it is a reduction in visible dust or finding yourself having fewer reactions or sleeping better through the night, the Blueair 503 is designed to remove a wide variety of indoor pollutants and allergens. Thanks to the HEPASilent filter, the Blueair does this with even the smallest allergens like cat dander! The 503 tests well in the CADR, a 375 rating across the board, and the internal design and filter structure is such that the 503 moves a great deal of air, quickly.

You can get 5 air exchanges per hour in a room as large as 22'x22'. 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. I like that Blueair designs their products to look nice as well as perform to high standards, and ultimately, many of us can't deny that even if an appliance is functional, if it looks like something from the prehistoric age of computers or too much like something you'd find in a factory or hospital, we're not going to want it in our living room. Maintenance is very simple. You simple open the top panel, pull the three filters and drop new ones in place every six months. Other than this, while your dusting you can clean the intake vents off from time to time, and that's it! 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. The optional SmokeStop filter provides added protection against odor and smoke. For me, this was the ideal filter instead of the standard HEPASilent filter. The SmokeStop filter has just under four pounds of carbon and does a good job and keeping dog odors down. Plus, it still retains the particle filtration of the HEPASilent filter. This filter style is also good if you have a smoker in the house, and overall the SmokeStop 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 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, low maintenance needs, and a universal appeal, this air purifier fits well into nearly any home.
