Memory is strongly bridged to our sense of smell. This is why it is imperative to breathe clean and fresh air. Not only does it reduce your chances of turning physically ill, it brings peace of mind too.

This is why air purifiers are the logical choice for your home and office. There is nothing more distracting and hazardous than cigarette smoke, allergens, pollen, mold and pet dander floating about unopposed in the air. Air purifiers are designed to battle them, and they have done so for years.

When it comes to good air purifiers, we want them to eliminate smells rather than add new ones. A good purifier is one that remains unnoticed. We needn’t look further than Blueair’s Blue Pure 211+ and Blue Pure 411. They tick all the boxes.

But which one is better? Let’s dive into it.

Design

Blue Pure 211+
BlueAir has opted for functionality with their Pure 211+. The purifier is basically a white box 20.4’’ high, 13’’ wide and 13’’ deep. It has three-stage filtration system: two internal and one external fabric filter.

The external fabric filter covers the bottom half of the box, and it comes in a selection of colors, allowing you to choose one that will fit the colors you already have at your home or office.

Blue Pure 411
The principle is the same. You get to choose the color of the external filter, but instead of a square box, you get a slightly smaller cone – 16.7’’ high, 8’’ wide, and 8’’ deep. There is an upside and a downside to this.

The smaller frame gives the option of saving floor space but reduces the pumping power of the unit.

Verdict: The design comes short of being awe-inspiring, but is pleasing nonetheless. The 411 offers slightly more practicability due to its smaller size, meaning that it will take less floor space.

Fancy buttons or led lights are absent from both models. So, if you are looking for a dancing-ball type of humidifier, these are not it.

Three-stage Filtration System

Blue Pure 211+
The Blue Pure 211+ air purifier uses a three-phase filtration system. In the first phase, the air is sucked in through the external filter which traps the bigger particles, such as hair and dust mites.

Then the air passes through the second filter which removes allergens, pollens, mold and other irritants. And finally, the air passes through the carbon filter, eliminating smoke and odor-causing bacteria. The clean air is then pushed out by a fan off the top of the box.

This purifier can pump air the equivalent of 350 cubic feet a minute and can cover medium to large rooms of up to 600 square feet.

Blue Pure 411
You get the same filtration system as in the 211+ model. The design of the box ensures a 360-degree air intake – however at 120 cubic feet per minute due to its smaller dimensions. This means that the air of a mid-sized room of around 160 square feet will undergo full filtration in about 6-7 minutes, making the purifier especially handy after cooking sessions with smelly food or smoking.

Verdict: Both purifiers have a 360-degree air intake, but the Blue Pure 211+ is much more powerful at 350 cubic feet per minute. According to the folks at BlueAir, the Pure 211+ holds the highest CDR rating on the air purifier market.

Economy and Noise pollution

Blue Pure 211+
The Pure 211 is packed with a powerful yet economic fan. Despite the fan producing a powerful CDR rating of 350, the energy consumption is kept at a very reasonable 60 Watts per hour. Considering that a common heater ranges from 700 to 1300 Watts, uncluttering the air in your home has never been more worth it.

You can select the speed of the fan by pushing the only button as many times as you need. Despite the device lacking a ‘whisper’ mode, it emits very little noise at the low and mid fan settings. A specialized polypropylene filter media muffles the noise further, so you can sleep without any disturbance.

Blue Pure 411
The oval Blue Pure 411 air purifier is less powerful than its square-boxed friend. But you would be surprised to learn the difference.

The fan motor uses just 1.5 Watts, and this is more economical than an LED light. The results the machine is able to pull off with that amount of power are amazing. This means that it costs peanuts to keep it on all the time.

The purifier is also packed with a polypropylene filter media which kills the little sound emitted from the fan, gifting you the silence. It’s up to you whether you will fill it up with top music, friendly chatter or imaginary zzZZZzz symbols.

Verdict: Both purifiers are friendly to the environment and your wallet. The 211+ uses just 60 Watts, while the 411 is in a class of its own with a measly 1.5 Watts. Although the fans do not have the ‘whisper’ mode option, the little noise emitted at low and mid settings is further reduced by a special polypropylene filter media.

Blue Pure 211+ vs 411: Conclusion

BlueAir has hit oil with these two models. The Blue Pure 211+ is specialized at cleaning the air of larger rooms, but the Blue Pure 411 is a proud wearer of the ‘most-economic’ purifier badge. With effective, easy-to-maintain, three-stage filtration system, these BlueAir models tick all the boxes for a top quality air purifier.

Despite reports of both purifiers emitting a smell of newly produced plastic, it must be noted that this smell wears off after the first two weeks – much like with a new car – leaving you and your loved ones breathing an odorless and healthy air. The purifiers are perfect for people with respiratory conditions, new-born family members, and health junkies.

If you have a large space you want to remove irritants from, We recommend the Airmega 400. All of Coway air purifiers do an excellent job of attacking indoor pollutants, and we highly recommend any of them.

The Levoit Vista 200 air purifier has some strong suits, but in our opinion it falls short of carving out a meaningful niche for itself. Its ideal use would be in a small bedroom occupied by someone who is sensitive to noise.

With high end air cleaning performance and a whisper quiet fan, the Winix 5300-2 is the perfect combination of power and finesse. It cleared airborne particulates out of our smokey testing room faster than any other model.
