Air Doctor 3000 vs. BlueAir Blue Pure 211+ Design
The perspective on the design of Air Doctor 3000 is subjective. It is minimalistic, but the AirDoctor 3000 is bulky and heavy. The plastic feels, and semi-slanting contours of the side of the air purifier make it appear cheap and challenging to store in the closet whenever you are not using it.
On the other hand, Blue Pure 211+ is aesthetically pleasing. The designers of the air purifiers made an effort to make the design of Blue Pure 211+ chic.
First off, the Blue Pure 211+ has a square with soft edges. Such a design is ideal if you have kids at home running around because you don’t have to worry about them getting injured from sharp edges.
But one of the first things you will notice about the Blue Pure 211+ is the sleek yet minimalistic design.
Half of the lower section of the air purifier is covered with a stylish canvas, while the upper section is the industrial design that comprises the main fan outlet.
What Size And What Kind Of Airborne Particles Air Doctor 3000 And BlueAir Blue Pure 211+ Can Filter?
Air Doctor 3000 is large and bulky, but the size of the air purifier compliments the CADR rating and coverage. The air purifier’s motor is powerful enough to filter the air of an entire living room or conference room.
However, the size of this brand is also a flaw because it makes them difficult to store whenever you are not using them.
But the selling point of the AirDoctor 3000 is its UltraHEPA filter system. The air purifier brand offers a four-filtration process that eradicates viruses and harmful pathogens by releasing ions to improve air quality.
The AirDoctor 3000 filters ultra-microscopic particles down to PM 2.5, and it is more than capable of eliminating viruses and pathogens down to 0.003 microns.
Aside from viruses, it also filters VOC (volatile organic compounds), toxic fumes, gas, unpleasant odors, pollens, and microscopic pests like dust mites and fungi.
Blue Pure 211+ is also large and ideal for wider spaces. However, it is a lot easier to store because of the symmetrical edges of the air purifier. And it is also effective enough in filtering and eradicating particles and allergens in the air.
It offers a polypropylene particle fiber that sucks 99.99% of particles down to 0.3 microns. You can rely on Blue Pure 211+ to eliminate allergens, smoke, gasses, VOCs, fungi, dust particles, dust mites, and hair from your pets.
