Blueair Blue Pure 211 Air Purifier Review

When allergy or flu season is just around the corner and you dread the thought of dealing with stuffed or runny nose, you need to arm yourself with a dependable air purifier. If it comes to air purifier for large rooms, the Blueair Blue Pure 211+ sure looks like an amazing choice.

But is it really a good choice?

In this review, we’re going to discuss the Blue Pure’s design, build quality, performance, and price to value ratio. When all things are accounted for, we’ll give you our verdict of whether or not this air purifier is a good choice for you.


The design of the Blueair Blue Pure 211 is definitely the first thing that strikes you about this air purifier. It’s simply a box with rounded edges, but the combination of 50/50 white and blue is appealing to the eyes.

The bottom blue half of the Blue Pure is actually the fabric pre-filter. The cool thing is you can switch it to various other colors such as grey, pink, yellow, and black. You can make this unit stand out of blend with the rest of the décor.

Weighing 13 pounds and measuring 13 x 13 x 20.4 inches, this unit is still within a manageable size and weight should you need to move it around the house.


This unit is encased in a durable metal cage. It feels solid and looks like it can withstand a couple of rough treatments in the months and years it’s in service.

We’re not too fond of Blueair’s 1-year warranty. Thankfully, you can extend it to 2-year warranty simply by registering your unit.


The Blue Pure air purifier is rated for 540 square feet room. If you have a large living space, you can run just this one instead of running multiple air cleaners.

The 360o air intake makes it superb at sucking in dirty air from all direction. Once the dirty air goes through the fabric pre-filter on the bottom, it then goes to the particle filter.

blueair air purifier reviewThe particle filter in this unit is not a true HEPA filter. That said, the filter is able to trap 99% of airborne pollutants like dust, pollen, smoke, pet hair, dander, mold, and bacteria. If you have asthma or allergy, you will be able to breathe freely the first day you run this air cleaner.

The Blue Pure 211+ is also very effective at trapping the nasty PM2.5.

“PM2.5, what’s that?”

PM2.5 is particulate matters that have a diameter of 2.5 microns or less. These nasties are able to penetrate deep into your lungs, wreak havoc on your cardiovascular system, and hammer down on your life expectancy.

“Can it reduce bad odor too?”

Of course, it can. The Blue Pure 211+ has a carbon filter whose job to adsorb odor-causing airborne particles. Whether it’s smell from cigarettes, the kitchen, new paint, mold, or pets, this unit does a great job reducing all of them. As a result, your home is not only filled with cleaner air but also fresher smelling air.

Blueair claims this unit can remove Volatile Organic Compounds (VOCs) too. If VOC is a major concern for you, we recommend adding air purifying plants in your home to boost VOC removal even further. Watch the following video and pick the ones you can get easily.

There are three fan speeds available and this unit is quiet on the first and second speed setting. You’ll notice the sound coming from this unit on the highest speed setting. Still, it’s not loud enough for you to raise your voice during a conversation or when you’re watching the TV.

Unfortunately, this unit doesn’t have any built-in timer or auto mode, so you can’t just turn it on and it adjusts its cleaning speed depending on the air quality.


Even though this air purifier is meant to be used in large rooms, it only uses between 30 – 61 Watts of electricity. Suffice to say electricity bill will not be a burden in the years this unit is in service.

blueair reviewFilter replacement is a different story altogether.

The particle and carbon filters require replacement every six months. We did a quick math and the result is the filter replacement will cost you ten bucks a month. It’s a good thing the fabric pre-filter is washable so you can use it over and over again to extend its lifespan.

We do need to remind you that this air purifier works really well, so you will need to vacuum or wash that pre-filter quite often.


If you want a gorgeous-looking air purifier with washable filter that can get rid of common allergens, bacteria, and PM2.5 while reducing bad odor at the same time, the Blueair Blue Pure 211+ makes a great choice. Its overall quietness makes it an appealing choice for living room and bedroom use.

That said, we must remind you that the cost of filter replacement will set you back ten bucks a month or about thirty cents a day. If you can live with that, then go ahead and buy this air purifier. It will do wonders cleaning the air you breathe, improving your family’s health as well as your own.
