Blueair 501 Air Purifier Review

MSRP: $549


OVERVIEW: As my Aerus Electrolux Air Purifier Review I recognized the real manufacturer of this unit is not Electrolux. While I have no issue with in home selling, or the Eletrolux name, the added on Air Purifier is a very, very profitable item. I review the unit itself but here's a link to the same model for 75% less. .

The price is a bit high

This model is good for particle removal (dust and pollen) but won't help much with germs, odors, viruses, or bacteria. This is the tradeoff many companies make - remove dust and pollen and skip ultraviolet and other germ/virus technology to keep prices low.

The motor is an older brush style. Todays brushless motors are much more efficient with energy, quieter, and last longer. But this one seems solidly made. This Aerus Electrolux Air Purifier Review will be followed by video reviews on the other models I have.

Blueair 501 Air Purifier Review

Blueair Company History

While Blueair is originally from Sweden I'm not sure if it is still made there. I understand that they have some of the parts made in China now. Founded in 1996 they have established themselves as a worldwide player in the air purifier field.

OTHER Blueair BRAND MODELS include the 203, 270E, 303, 403, 450E, 550E, 603, 650E, and ECO10.

Pros and Cons


1 - A Filter Change Indicator Light tells you to reorder a filter - so as not to void the strict warranty

2 - Solid steel construction

3 - Wheel casters make it easy to move (and it is big)

4 - Quiet on Low Speed (but the quiet speed is not very effective). Loud on high due to an older style brush motor.

5 - Energy Efficient Fan Motor


1 - Not a real or what's called "true" Hepa filter - it's 'Hepa-like"

2 - The absence of a pre-filter, means shorter filter life (6 months) as a result - more expensive than most HEPA's to operate

3 - The seating of the filters inside the housing is not very tight. This might allow some air to by-pass the filter reducing the air cleaning efficiency, However the 3 filters probably offsets this.

4 - Does not kill viruses, bacteria or mold/mildew. The odor ability is less than desired, although the electrostatic probably covers odor.

The Blueair 501 air purifier is one of the air purifiers which can handle cigarette smoke, and I recommend it if you smoke. Although the HEPA filters will cost you a lot of money. An electrostatic air purifier or Ozone might be better on the wallet for smoke.

On the allergy end it does a good job, but is a bit expensive and I might recommend something that does as well for a lower price if that is your problem. It's also big, very big, so if you have a small room, or limited space I'd find something else. The comparison chart via the link below or the menu above can offer some alternatives.
