Blueair Blue Pure 211+ Design and Color options

Since air purifiers are generally placed in your bedroom or living room as any other piece of furniture, their design is quite important for a lot of users out there. Thus, a lot of you would be interested in knowing more about the design of this Blueair air filter to make sure that it fits your room just right in terms of the aesthetics.

It has a two tone color scheme with different colors in the top and the bottom portions along with a single button in the middle. This button is used for controlling different things and features of this air purifier. While it is comparatively compact, it still takes some floor space. If that happens to be your issue, you must consider installing an air purifier that can also be wall mounter. Our top recommendation would be the Rabbit air Minus A2.

Unlike most other air purifiers out there, this Blue Pure air purifier has a functional design as its outer fabric layer acts as a pre-filter for the air. And this fabric layer also adds to the aesthetics of this small and compact air purifier that weighs just 12.5 pounds. Talking about its dimensions, it is rated at 13 inch x 13 inch x 12 inch.

2. Purification Stages

Purification Stages in Blue Pure 211+ Air Purifier

Since the sole purpose of an air purifier is to clean the air around you, checking its purification process is highly important. This process includes multiple purification stages including the following ones all of which are equally useful for cleaning air:

I. Pre-Filter

As mentioned earlier, the Blueair Blue Pure 211+ air purifier comes with a fabric layer on the outside. While this covering is mainly made for aesthetics, it also works as a pre filter. Even though it does not remove any small particles, it certainly helps in getting rid of larger particles like dust while looking good.

Due to this, the internal filters of this air filter have fewer things to clean from the internal filters of your air purifier. A great thing about this pre-filter is that even if it gets dirty over time, you can easily clean it using a vacuum or a washing machine.

II. Preliminary Particle Filter

Once the air gets inside this air filter, it is made to go through the preliminary particle filter which happens to be the most important one. Generally, this particle filter is a HEPA filter in most air purifiers out there. But Blueair uses polypropylene fibers instead of HEPA filters that allows this air filter to catch up to 99% of all particles in the air inside your home or office. When compared to an HEPA filter, it performs quite similarly as it can get rid of allergens, dust, pollen, dust dander, fungi, and various other things. It’s just that the filter isn’t universally approved for any performance standard. If you have a pet and pet dander is your major concern then do read our article on the best air purifier for pets.

III. Activated Carbon Filter

After going through the particle filter in the form of the polypropylene fibers, the air then passes over to the activated carbon filter. This filter uses a lot of activated carbon material that is there to get rid of odour and gases from your air. In other words, if there is any foul smell in your room’s air, this carbon filter can easily get rid of them.

3. Blue Pure 211+ Air Purifier Coverage

Blueair Blue Pure 211+ Air Purifier room coverage review

If you are using an air purifier at your home, office, or anywhere else, then it should be able to clean everything from the air despite the room size. But to ensure that it works fine in large rooms, you have to check the coverage area of any given air purifier.

Thankfully, Blueair’s Blue Pure 211+ air purifier offers a pretty high coverage area of up to 540 square feet. As compared to other large room HEPA air purifiers, this range is somewhat moderate.

4. Noise

There are so many air purifier users out there who leave their air filter turned on 24 x 7 to ensure that the air is clean at all times. While there are no performance issues regarding this, a loud air purifier can be quite frustrating during the time you are sleeping. Thus, you should check the noise emission levels of a given air purifier before buying one.

The Blueair air purifier mentioned in this article has a noise level rating of just 31 decibels at the lowest setting that is very low. And even if you are running it at the highest setting, it goes to just 52 watts which should be lower than your air conditioner.

5. Blue Pure 211+ Energy Efficiency

Since air purifiers generally keep running at all times, they can consume a lot of electricity over a long period of time. And if electricity is expensive in your area, this can add quite a lot to your electricity bill.

Therefore, checking the energy efficiency is highly important which is given in watts. As for the Blue Pure 211+ and its energy efficiency, its energy consumption ranges from 30 watts to 61 watts. When compared with other similarly performing options out there, this air purifier has a pretty great energy efficiency.

6. Price

Even if a given air purifier offers everything that you are looking for, buying it only viable if it has the correct price. In other words, you should look out for value for money air purifier models out there if you are in the market one.

Thankfully this Blueair has a very justified price tag when you consider the given features and performance. In fact it is one of the cheapest options out there compared to other similarly performing options.


After going through this Blue Pure 211+ review and all of the details mentioned in it, you must know a lot about this Blueair air filter.
