Some Similarities and dissimilarities between Blueair 211 vs 411

Although they have many standard features, they also have some differences like:

One Button Control

Blueair did not provide as many advanced features. So with both air purifiers, you will have the ability to clean the air with just one touch of a button. One single button resides on the front of the Blueair 211 vs 411 air purifiers, which are great to use as they only contain settings to switch between gears and set the Filter Reset Indicator.

Size and Weight

Both blue air purifiers have different sizes and weights. The blue air 211 purifier is larger than the blue air 411 purifiers. Blue air 211 is about 13 inches long, 13 inches wide, and 20.4 inches high. While blue air 411 is about 7.9 inches long, 7.9 inches wide, and 16.7 inches high.

Space cover

These units offer different features and benefits, so a quick study will help you decide which unit is best for your needs. For example, the Blueair 411 purifies the air in small rooms up to 161 square feet, while the Blueair 211 can purify the air in rooms up to 540 square feet. Nevertheless, they both filter the air every 12 minutes, and the particulate levels in your room will be lowered.

Filter system

Utilizing Blueair’s revolutionary HEPASilent Technology, the Blueair 211 vs 411 can filter up to 99.97% of airborne pollutants. The 411-model is a three-layered filtration system consisting of a pre-filter, a particle filter, and an activated carbon filter. Thanks to its filter, it is a highly-rated model that can be cleaned and reused. The first layer traps dust and allergens, while the next one absorbs things like allergens, germs, and particles. Replacing your pre-filter on your vacuum with this should allow you to save some money in the long run.

Although the filter system works on the same functions, the difference is that blue air 411 has around 360 filter systems while blue air 211 has a simple three-layered filtration system.

The noise level of blue air 211 is very low, about 31 dB at slow speed and 56 dB at high speed. While the noise level of blue air 411 is very low, about 18-48 dB, that is quieter than a whisper.

Power consumption

The Blueair 411 was initially created for small spaces, such as office cubicles. It has a much smaller system and is meant to be placed on your desk, taking up little room and emitting enough air to keep you from getting sick at work. The Blueair 211, on the other hand, is made for larger rooms, including some open areas in a house or an office building. So blue air 211 consumes more power, about 30 – 6 W. While blue air 411 consumes less power, about 1.5 – 10W.

Which Blueair Purifier is better? Blueair 211 vs 411

The Blueair Classic 211 is a purifier that can clean almost any size room up to 540 square feet. Although it was designed for medium-sized rooms, we found that it works great in smaller spaces. It doesn’t have a timer, but it has a low-volume automatic mode for nighttime use. We were impressed by how efficient it is, even with larger rooms, achieving high scores on all of our air quality tests with an excellent rating overall. We found the only significant downside was its large size and high price tag.

If you are looking for something to remove odors or smoke in your home or office, there isn’t a better option on our list. If you don’t need as much power, though, we recommend checking out the Blueair Classic 411, which has a similar design but is slightly less powerful. This model has been shown to remove 99% of dust particles from the air and effectively neutralize common household odors, including cigarette smoke. It also comes with two pre-filters that should be replaced every six months depending on usage. 

Overall, both options provide excellent performance at an affordable price point, so you won’t go wrong no matter which one you choose!
