Many people suffer allergic reactions from airborne particles. Most of these pollutants are so tiny they can’t be seen by the naked eye, so when you think you cleaned every part of your house, think again.

Is the air your family breathes pure and allergen-free? If you yourself complain of stuffed or runny nose every morning, or perhaps your child has breathing problems, then you might need an air purifier.

There are plenty of brands to choose from, and one of the most popular is Blueair. Here, we’re putting the spotlight on the Blue Pure 121, an 8.25-kg. air purifier that promises to “let fresh air out” so that you can “breathe freely.”

But does it deliver good results? What are its pros and cons? Let’s find out in this Blueair Blue Pure 121 review.

What are the key features of the Blue Pure 121? Here’s what to expect.


The Blue Pure 121 has a 3-stage filtration system. Each stage comes with a different filter: a fabric pre-filter, a particle filter, and a carbon filter.

The pre-filter is responsible in trapping large particles such as har and dust mites. If you have pets at home, this is where you see some pet hair/fur. The particle filter removes allergens, pollen, molds, and other irritants. The carbon filter eliminates smoke and odor-causing bacteria.

Theoretically, the Blue Pure 121 can get rid of a variety of airborne pollutants such as smoke, kitchen smells, dog odor, pet dander, VOCs, and yes, allergens.

Coverage Area

The Blue Pure 121 is designed for “extra-large rooms” of up to 620 sq. ft. When it comes to size, this is an upgraded version of the Blue Pure 211+.

What’s in the Box?

Expect to find the following: the Blue Pure 121, a collapsible carbon filter, and two fabric pre-filters with two different colors – dark shadows and diva blue.

Several buyers who are allergy sufferers have noted a significant difference before using the Blue Pure 121. With this air purifier, the “sniffing” is gone, says one person. And so is the “runny nose.” It helps in reducing dust and molds.
