BlueAir 211+ Review

BlueAir Pure Blue 211+ Air Purifier

AirHonest Award: Best Over-all BlueAir Air Purifier


  • Energy efficient 
  • Activated carbon filter
  • Quiet motor
  • 3-stage filtration

BlueAir’s 211+ air purifier is one of the more affordable options while being incredibly efficient as it uses up just 60 watts while you have it on the highest setting. Therefore, you’re able to keep the air in your home clean while saving on energy.

It’s a fantastic air purifier to use in bedrooms due to how quiet it’s able to function. This is a result of the polypropylene filter media that has been fitted to the machine. It works to filter plenty of air while being used on the lowest setting so that you can keep the air in your bedroom clean as you sleep.

The 211+ model takes in air from every side. Therefore, it’s effective at drawing in plenty of air to remove more airborne particles from your home. 99% of pollutant particles, such as pollen, pet dander, dust, bacteria, and mold, can be filtered.

We were also impressed with how a carbon filter has been implemented to the machine as it’s great for removing odors in the air. Not to mention, the pre-filters can be easily rewashed so that the air purifier can continue working well for longer.

Pros 👍
✔ Highly efficient
✔ Carbon filter for removing odors
✔ Quiet function
✔ 3-stage filtration

Cons 👎
✘ The power indicator is very bright
✘ Some notice it produces a smell
✘ Not so effective for pet hair

Buyers Guide On BlueAir Air Purifiers

Filters Type Guide


The pre-filter is essential when it comes to air purifiers that have HEPA filters. This is because the pre-filter works to capture pollutant particles that are larger to prevent them from clogging the HEPA filter. For the most part, pre-filters can be washed and reused over and over again.

A true HEPA filter is the highest-quality filter that’s available. To qualify for being a true HEPA filter, there are strict rules that it needs to pass which have been set by the Department of Energy (DOE) in the U.S.

To pass the regulations, the filter must be able to capture 99.97% of pollutant particles that are 0.3 microns in size. Their ability to capture so many tiny pollutant particles is what makes true HEPA filters the best kind available.

For the most part, true HEPA filters need to be replaced every 6 months to a year to make sure they can continue working effectively. However, there are permanent true HEPA filters available with other air purifier brands.

HEPA Type Filter

HEPA type filters are a version of true HEPA filters that don’t work as effectively. This is because they don’t have to pass the strict regulations set by the DOE and they’re usually available with the cheap air purifiers.

Activated Carbon Filter

Activated carbon filters are fantastic for filtering pollutant particles that cause odors that can be caused by pets, chemicals, smoke, and chemicals.

Ionic Filter

Ionizer filters work differently to HEPA filters by emitting negatively charged ions that latch onto pollutant particles, instead of sucking air in and filtering the pollutants.

When the negatively charged ions attach themselves onto pollutant particles, the particles come lower to the ground where they can be collected on a plate. However, ionizing air purifiers can cause more irritation to people with asthma.

Ultraviolet Light

UV light systems in air purifiers work by targeting virus-causing bacteria and cause them to become sterilized.

Air Purifier Capabilities & Size

One of the biggest factors that you’ll need to consider before deciding on which air purifier to install in your home is the size of your room and the capabilities of the machine.

Be sure to check the size of the room that your chosen air purifier has been made to work effectively in. To make things easier, we recommend that you measure your room in square feet and ensure that you choose an air purifier that’s suitable for it.

BlueAir’s air purifiers come with different capabilities that range from 100-300 square feet, which are more inexpensive compared to the ones that can be used in rooms that are 700-800 square feet and more. If the air purifier is meant for a much larger room than yours, it will be using up more energy than necessary.

You can learn more about some of the best air purifiers for large rooms by checking out this post. 

On the flip side, if you install an air purifier that’s too small for the size of the room, there will be more pollutant particles left in the air.

You’ll also want to consider the dimensions of your air purifier if you were interested in setting it up somewhere in an office or at home where it’s out of the way. Some people may not be too concerned with the size of their air purifier if they’re looking to use it in larger rooms.

Frequently Asked Questions

What does “CADR” mean?

CADR stands for Clean Air Delivery Rate and this provides you with information on how effective an air purifier is at cleaning the air within a room of a certain size. CADR ratings usually involve separate numbers for the different pollutants that include smoke, dust, pollen, and pet dander.

If you wanted to use an air purifier for a more specific pollutant, you can check the CADR rating for that pollutant as a way of comparing different air purifiers.

What does “ACH” stand for?

ACH stands for Air Exchanges per Hour and it gives you useful details on the number of times that an air purifier can clean the air in a room each hour. You can find these ratings in the form of “No. X”.

For example, an air purifier with an ACH rating of 5x means that it can clean the air in a room up to 5 times an hour.

Tips For Purifying the Air In Your Home 

  • Avoid smoking indoors as it makes the job of air purifiers a lot harder. 
  • Having plants in rooms can boost oxygen levels to help the air become naturally cleaner. 
  • Store items such as solvents and paints away from the house and in a shed or garage. This is because they release chemicals that cause odors and potential harm.
  • Be sure to vacuum your home regularly to ensure that pollutant particles in carpets and on your floors are prevented from being pushed back up into the air. 
  • Airing out your home regularly by keeping the windows open can enhance circulation and help towards pollutant particles going outside. Although, people with allergens may want to avoid this during seasons where pollen is high as it can worsen their allergic symptoms.
