Purification Performance

The setting? Our medium-sized office space, reminiscent of a startup’s first venture. We employed the Temtop LKC-1000S+, a top-notch air quality detector, the equivalent of a hedge fund’s leading analytical tool.

Then, I let the BlueAir Pure 211+ run on the highest setting for 1 hour and the air quality to get another set of measurements.

We can then compare the difference between the starting baseline and the post-run data to determine the performance of the BlueAir Pure 211+

Starting Baseline

PM2.5: 9.5

PM10: 17.1

Particles: 1299

AQI: 39

After 1 hour

PM2.5: 0.1

PM10: 0.2

Particles: 15

AQI: 1

The BlueAir Pure 211+ worked its magic, slashing the pollutants in the room by a jaw-dropping 98.8%.

The BlueAir Pure 211+ improved PM2.5 air quality by 98.9%

Below, we’ve included information on the testing criteria and what defines good vs. bad air quality.

Overall, the performance of the BlueAir Pure 211+ was excellent. In our tests, it brought the PM2.5 down to 0.1, which is exactly what we are looking for in a high-performance air purifier. I would have liked to see the PM10 brought down to 0.1 as well, but 0.2 is still fantastic.

The Filters

The BlueAir Pure 211+ uses a 3-part filtration system with the option to double up with the pre-filter. Imagine a team of filters, each playing its part flawlessly.

Here are the included filters:

Optional pre-filter cover
Pre-filter
HEPASilent filter (technically it’s not a HEPA filter)
Activated carbon filter

Pre-filter: The forward player, grabbing the larger pollutants.

The HEPASilent filter is the main filtration system, capturing air particulates as small as 0.1 microns. According to BlueAir it removes 99.97% of airborne particulates. Not technically a HEPA filter, but its performance? Equivalent to an NBA star’s slam dunk.

Activated Carbon Filter:Eliminates VOCs, the unsung hero, making sure your room doesn’t just feel fresh, but also smells clean.

Noise Test

We also tested how loud the air purifier was while running. To perform this test we have the air purifier run on the three different modes and use a sound meter to measure noise level. We tested the BlueAir Pure 211+ from about 3’ away.

Our results showed the following decibel levels from each mode.

Low

23.4 dB

Medium

32.9 dB

High

45.0 dB

A range of 23-45 dB is about what you would expect from a device of this size and coverage. In a noisy stock market, our device remained the silent, stable stock. On its loudest mode, it emitted a soft 45.0 dB – imagine the serenity of a quiet library.

Common noise levels:

20 dB – rustling leaves
30 dB – whisper
40 dB – quiet library, babbling brook
50 dB – refrigerator, moderate rainfall
60 dB – normal conversation, dishwashers
70 dB – traffic, showers
80 dB – alarm clock, telephone dial tone

Usability Tests

In a world of complicating tech, BlueAir goes against the grain. Just like the greatest strategies, sometimes, simplicity is key.

Here’s what is included in the box:

Pure 211+ air purifier
HEPASilent filter (in device)
Pre-filter in Diva Blue
Pre-filter in Dark Shadow
Manual

Setup

Setting up the Pure 211+ is simple and takes a few seconds once it is out of the box. Before plugging it in, make sure to remove the plastic from the filter and cover the device in your choice of fabric pre-filter. After doing so, the device is ready to be plugged in and turned on.

If you plan to use the AirVisual app, make sure to keep the tag with the QR code that comes attached to the box as you will need that during setup.

Controls

The BlueAir Pure 211+ lacks most of the common usability features we see from many others. Missing features like app connectivity and an auto or sleep mode. While this is disappointing, excellent air purification performance was clearly the design priority.

Because of this, the only controls on the device are a singular button on the front of the air purifier. Tapping this button will turn the Pure 211+ on/off and cycle through the 3 power options. That’s it, beyond the singular button, there are no other controls on the device.

Maintenance

The main item of maintenance needed to keep the BlueAir Pure 211+ up and running is replacing the HEPASilent filter.

BlueAir states the expected filter life as 6 months, but that can vary depending on use.

The air purifier does have an indicator light that will let you know when the filter needs to be replaced.

Otherwise you will need to occasionally clean the fabric pre-filter, which can be vacuumed or machine washed as needed.

Size & Dimensions

The BlueAir Pure 211+ is a larger device with a large coverage area. It can cover up to 540 sq. ft. with 4.8 air changes per hour. Because of the size, I found the device a little hard to move.

The fabric pre-filter can feel slippery while you carry the device, so make sure you have a secure grip on the Pure 211+ if you decide to pick it up.

With its commanding presence, it stands:

Length – 13”
Width – 13”
Height – 20”
Weight – 12.5 lbs.
