What do you think is the scariest thing in your home?
Is it the oven, iron box, refrigerator, or garbage disposal? While all these things are dangerous if not handled properly, they are not the scariest thing in your home. The scariest thing in your home is the unfiltered air.
If you spend more than 90% of the time indoors, you expose yourself to many pollutants.
If you and your family have respiratory problems, you are at a higher risk. Pollutants present indoors include airborne bacteria, viruses, VOCs, carbon monoxide, and mold.
To trap or remove these pollutants faster in a large room, you need a high airflow air purifier. In this post, we will talk about the Blueair Blue Pure 121 air purifier, which is perfect for medium-sized, and large rooms.

Stay tuned to find out more.
Proprietary Filtration System
The Blue Pure 121 has a total 4 stage filtration system, 3 stages of mechanical filtration system, and one stage electronic filtration. The mechanical filtration composed of a fabric pre-filter, a particle filter, and an activated carbon filter.
The fabric pre-filter is the first stage. It traps large particles such as pet dander, pet hair, and lint.
What you need to know is that the unit comes with two washable pre-filters. One is dark blue, and the other is gray. You can buy different colors to customize the look of your air purifier to match your home decor.
Cleaning the pre-filter is easy. You can vacuum or toss the pre-filter in the washing machine.
The second and third stages are the particle and activated carbon filters. This particle filter helps to trap and remove 99% of contaminants from the air. Made of dense fibrous material, it traps PM2.5 particles.
Such particles include pollen, dust, mold spores, dust mites, and smoke. When the air flows through the carbon filter, it absorbs the odors and VOCs. What you need to know is that you can upgrade the filtration system with Extra Protection Filter.
This filter has activated coconut carbon pellets. They absorb odors, chemicals, and heavy gases from your home.
The electronic filtration system used in Blue Pure 121 is an Electrostatic precipitator (ESP). It makes pollutants stickier, so they can easily be trapped on the mechanical filters.
This is a unique combination of mechanical and electrostatic filtration, which they named HEPASilent. Due to this technology, Blueair uses less dense filters. Also, they are quiet and energy-efficient.
Sleek and Modern Design
Blueair is popularly known for making smart home solutions with a sleek design. Measuring 13 by 13 by 28.3 inches, the unit has a box-like design that blends well with modern, contemporary home decor.
It has a 360-degree intake covered by the fabric pre-filter. Since the pre-filter covers the intake, you can change the color to match your space. Available colors include Diva Blue, dark Shadow Gray Pink, and Yellow. If you prefer a Scandinavian look, you can remove the pre-filter to show off the sleek white-mesh frame.
But doing so means buying the Extra Protection Filter to boost the efficiency of the other two filters.
At 18.2 pounds (8.26 kg), the unit is not lightweight but portable. To place the unit in your room, make sure it’s in an upright position on the floor. It’s essential to place the unit where there is no foot traffic.
Do not place the unit 10 cm closer to another object. This will disrupt the flow of air in and out of the unit. Avoid placing the unit near wet areas or close to heat sources like fireplaces, radiators, and ovens.
Lastly, we have a one-button design. This single button allows you to control the unit. That includes changing the fan speed and even learning when to replace the filter. For optimal performance, the manufacturer recommends replacing the filters every 6 months.
The unit has three-speed control options. You can change the fan speed using the single button on the unit. To set the fan at the low fan speed, press once to turn the unit on and set it to low fan speed.
For medium fan speed, press the button twice, and for high fan speed, press the button three times. The unit has a high CADR of 400 cfm. It can clean a room size of 600 square feet five times in an hour.
As such, it’s perfect for your living room and bedroom.
The unit has an Auto Start feature. It can automatically restart at the set speed if you use the power switch timer or due to power failure.
It’s energy-efficient, and at the lowest fan speed, it consumes 30 watts. At the highest fan speed, it consumes 61 W. This means it consumes less than traditional light bulbs at the lowest fan speed. It’s 40% more efficient compared to standard air purifiers.
As such, you can run it for 24 hours without concern about power consumption.
The air purifier uses specialized polypropylene filter media. It processes more unfiltered air resulting in more clean air. While doing so, it produces less noise. At the lowest fan speed, it produces 31 decibels.
This is comparable to rustling leaves or a whisper. Also, it’s below the average home noise at 40 dB. At the highest fan speed, the unit produces 56 dB(A). This is below a normal conversation or music playing in the background.
