Our Verdict

Packing in more power than any of the other models we tested, the Blueair Pure 211+ provides high-end cleaning performance to rooms of up to 525 square feet. However, with great power comes great responsibility, and in this case, by responsibility, we mean cost. It costs quite a bit upfront, and even more over its lifetime. This was the highest lifetime cost we calculated by far and took the Blueair out of contention for our highest honors. However, it is incredibly capable, and if you don't mind incurring extra costs to make sure you're large living room gets effective air cleaning, this product will serve you well.
Excellent air cleaning performance

Our Analysis and Test Results

Performance Comparison

The Blueair is a high scoring air purifier that excels across the metrics, particularly when it comes to air cleaning performance and noise levels.

Air Cleaning Performance

The Blueair shares the top score with three other models in our air cleaning tests. It is just a hair better than the other top-performing models, but not to enough of a degree to warrant a higher score. After a half-hour fighting the haze in our smoky testing room, it had reduced airborne particulate counts by 98.97%, and just 15 minutes later, it improved to 99.95%. It held that level until the end of our hour-long test. That was the highest reduction percentage we saw in our testing.

Its CADR (clean air delivery rate) of 350 is also the highest of all the models we tested and gives it enough power to handle rooms of up to 525 square feet. Unless your house was once featured on MTV Cribs, chances are that will be enough for any room in your home. The only downside is that it doesn't have a carbon filter, so it didn't do much for odor. However, the models with carbon filters barely did much better, so we wouldn't let this dissuade you away from the Blueair.


The Blueair is again near the top of the leaderboard in our noise testing scoring. When set on high, the Blueair is actually similar to the Coway, with a medium pitch that is noticeable but consistent and mellow enough that it will likely fade into the background once you get used to it. On low, it makes a very quiet hum that you may notice while doing quiet activities like reading but is by no means annoying. The Coway is a bit better in this regard, as it is nearly silent on low.

Ease of Use

The Blueair is an average scorer in our ease of use testing. It is very simple to use, as a single button lets you turn it on and off and cycle through three fan speeds. Considering how powerful it is, the weight is quite low at 12.2 pounds, so it's not too difficult to move around. It lost points because of its lack of feature; we would have expected a model of this caliber to have more fan speeds and at least an automatic off timer.

Operating Cost

Its estimated lifetime cost is $1,105, which is much higher than the costs of any of the other models we tested and nearly double the average. This starts with a fairly high but not unreasonable list price. It gets compounded by the fact that replacement filters cost $70 and must be replaced twice a year. It is also one of the more power-hungry models we tested, incurring estimated annual electricity costs of $21.02.


The Blueair is a top-notch performer, but we wouldn't call it a particularly good value. It certainly demands a premium for its high performance. If you don't mind paying a premium to have a single unit that can clean a large living room, you'll be happy with the Blueair. Just remember that for the same lifetime cost, you could buy two Coway Airmega 1512HHs.


The Blueair Pure is an incredibly effective and powerful purifier, but that performance carries a large price premium, especially when you factor in lifetime costs. If you don't mind paying a big premium for a simple, aesthetically pleasing, and powerful machine, it is a great choice.
