Why Choose the Blueair Air Purifier Brand?

Filtration Technology

Blueair devices are made with ultrathin propylene filters of various sizes and layers. Through particle charging, they can remove as many as 99.97% of particles from the air.

Even when the filters are full, it keeps the pollutants locked in – reducing the possibility of cross-contamination.

HEPA Silent Technology and Quiet Operation

Compared to other air cleaners, Blueair purifiers are remarkably silent. In fact, you can sleep right next to them and not hear a thing. This quiet performance is due to its HEPA Silent Technology, which fuses electrostatic and mechanical filtration.

It’s so silent that you may need to check twice to see if it’s on.

Optimal CADR (Multiple Air Changes)

Clean air delivery rate (CADR) refers to the cubic feet per minute of air that has been purified. With that being said, the higher the CADR is, the better the purifier. It’s a good thing Blueair devices come with optimal CADR performance, with its 650ES model having the highest CADR in the market.

SMART Connectivity (Wi-Fi & Alexa enabled)

With its Wi-Fi connectivity, you can adjust your Blueair controls wherever you might be through the Blueair Friend app. To make things even easier, Blueair purifiers are also integrated with Alexa, Google Home, and Amazon Echo, enabling you to control your devices with a simple voice command.

With the app, you are regularly updated on your room’s air quality – including when you need to make a Blueair purifier filter change.

Particle & Odor Remover

Thanks to its ultrathin propylene fibers, Blueair purifiers can get rid of minute (PM 2.5) dust, yellow dust, pollen, and industrial emissions. They also come with active carbon SmokeStop filters that effectively remove odors and other foul-smelling pollutants from the air around you.

Energy Star & AHAM Certified

The Blueair company is one of the first ones to have all their air purifiers Energy Star certified. As such, this product can help you save money – while protecting the environment.

More importantly, Blueair Purifiers are also awarded the Portable Electric Room Air Cleaner Certification Seal by the Association of Home Appliances Manufacturers (AHAM).

Functional & Sleek Aesthetics

Apart from being extremely efficient, Blueair air cleaners are pleasing to the eye. A combination of innovative Swedish engineering and functional aesthetics, these products have been recognized in many local and international design awards.

Manufacturer Warranty

Blueair products come with a 1-year warranty as standard. Should you wish to be covered by replacements and repairs for up to 2 years, simply register your device on the Blueair website or Blueair app within 60 days of purchase.

VOCs or volatile organic compounds can cause irritation, nausea, even liver or kidney damage. Often omitted by household cleaning chemicals, our homes are often full of VOCs, which can damage our loved ones’ health.

While they’re hard to avoid, you can protect your family from these substances with the Blueair Blue Pure 121 purifier’s help.

The filtration power is primarily due to its foldable combo filter with a 360-degree air intake. Made with 2.5 pounds of granular activated carbon, it can keep large spaces free from smoke, gases, and of course, harmful VOCs.

Despite its titan-like power, the Blue Pure 121 has a relatively small frame. Measuring 28.4x13x13 in, you can place it easily in areas such as basements, offices, and en-suite bedrooms to keep your air free of harmful toxins. It’s also incredibly transportable, allowing you to move the filter around to where it is needed most.

One of the downsides of this model is that it doesn’t come with a sensor/timer, meaning you’ll need to keep the purifier running to maximize it’s air cleaning capabilities.

As with similar models, it also comes with a Blueair purifier filter that’s easily washable. By cleaning this filter routinely, you could extend filtration life to up to a year.


  • Excellent air filtration performance

If you’re particularly fond of smart devices, then you can’t go wrong with the Blueair Sense+, which in our opinion, is the best smart air purifier on the market today. With the help of the Blueair Friend app (downloadable in the App Store/Google Play Store), you can monitor your Blueair device wherever you may be.

And that doesn’t mean it’s only useful when you’re away from home. The beauty of owning a smart device means you can place your air purifier in hard-to-reach areas that could be less visible.

Apart from the app, you can also use Alexa to modify the device’s settings. You can easily tinker with the fan speed, activate the child lock, and turn on the night mode without having to access the device itself.

More than just a ‘smart’ gadget, the Blueair Sense+ holds true to its promise of cleaning pollutants from the air. With its particle and activated carbon filters, you can free your surroundings from heavy gases and many other harmful chemicals.

Although the device is a little more expensive than some of the other choices on our list, the ‘smart’ features more than compensate for the additional cost.

The beautifully-crafted Blueair Sense+ also allows you to choose from 6 different colors. Pretty and smart, it comes as no surprise why customers clamor for the Blueair Sense+ purifier.


  • Wi-Fi and Alexa-enabled controls
  • Whisper-quiet operation

Comparing Blue Air with Similar Air Purifier Brands

Blueair Vs IQAir

IQAir models are more cumbersome and lack ionization features. As a result, Blueair purifiers prove to be superior in removing dust, pollen, allergens, and other pollutants.

Some Blueair models also come with air monitoring and auto mode, a feature not present in IQAir products.

Blueair Vs Dyson

Users prefer Blueair purifiers over Dyson for several reasons. One of the main selling points of Blueair is smart functionality. As mentioned in our review, you can remotely control your Blueair device through Alexa/Google or Siri, or your BlueFriend app.

Dyson also attracts a handsome price tag, so if you’re looking for something a little easier on the wallet, Blueair is an excellent option. While both fare well in filtering the air, Dyson comes with one advantage: it can also be used as a tower fan.

Dysons also come with futuristic looks, making them very unique, eye-catching, and decorative pieces for your home.

Blueair Vs Coway

In terms of particle reduction, Blueair products trump those of Coway. Although Blueair is a little ‘noisier’ than Coway devices, its filtering power makes it a superior choice.

Despite being more superior to Coway air purifiers, Blueair often comes with a higher operating cost (including electricity and replacement filters). On average, you will need to spend about $200 to operate Blueair annually, while Coway is about half of this.
