Blueair Pro L weight
46 lb (20.9 kg)
Blueair Pro L is a beautifully and elegant air purifier designed for office use or a very niche target group. Build quality is also impeccable as you would expect from this price range. For all the performance it can churn out, the dimension stands at only 20 x 31 x 10 in (50.8 x 78.7 x 25.4 cm) although 46 lb (20.9 kg) weight is no doubt heavy. What you do get standard from Blueair Pro L include a 3-stage filtration, HEPASilent Technology, filter replacement indicator, 3 speed with color display, zero ozone emission, CARB certified, Energy Star rated and 5 years warranty. There is no Wi-Fi support, no timer, sleep mode or even remote control (Auto mode is available with the addon Air Intelligence Module).

On to Usability and functionality, Blueair Pro L is as simple as it get with only 2 buttons for fan speed control. How the control panel works is extremely straightforward. By default there is no display as the air purifier is on standby mode. Click on the PLUS button to turn on Blueair Pro L and one blue bar (speed 1) will appear between the buttons. From there you can adjust the fanspeed between 1 to 3 using the PLUS and MINUS buttons. To turn off the unit, simply click on the MINUS button till there is no blue bar left. For unit with Air Intelligence Module addon, you can activate Blueair Pro L Auto mode simply by clicking on the PLUS button when the unit is running on speed 3. An indicator word AUTO will appear and the air purifier will automatically adjust the speed according to the contaminant levels. Also with the AIM addon is a two bar columns that show the levels of airsuspended particles (PM2.5) and gaseous contaminants (GAS). 1 green bar represents low particle or gas level while 3 bars (green, yellow and red) represent high level of particles or gas. Do note when the display will slowly disappear after 30 seconds even when the unit is running, simply click on any of the buttons to reactivate the display. As for filter replacement indicator, a red filter light will only appear when filter replacement is required.

HEPASilent Technology
^ Blueair Pro L filters/ technologies/ lifespan
What's powering Blueair Pro L is the highly acclaimed 99.97% efficient rate HEPASilent technology along with Particle and SmokeStop filter. HEPASilent Technology would work in the sense that both electrostatic and mechanical filtration joining side-by-side in combating airborne contaminants. How this works is particles that flown inside the air purifier would be subject to electrostatic charge. With all particles charged up therefore more clingy to the filter, Blueair particle filter will have an easy task trapping micron size allergens, bacteria and viruses. Same goes with the SmokeStop filter where it will focus on gases and odors instead. At the end of the cycle, Blueair Pro L will release out cleaner, purified air that contribute even lesser ozone that normal unpurified air.Blueair Pro L filter media is ultrasonically bond and made with waterproof, natural antibacterial polypropylene fibers that promises no mold and bacteria growth. The filter V-shaped design allows more filtration to be squeezed in so mroe particles can be captured and prevent from leaking out. The V-shaped format also closes like a book thus prevent you from being exposed to trapped contaminants when replacing the filters.

Power consumption

Blueair Pro L 32 - 55 dB(A) noise level is surprisingly low given how strong and punchy the airflow delivery is. Thanks to the German Engineered fans, at low speed is whisper quiet while at max speed is no more than normal conversation noise. 22 - 170 W Power consumption on the other hand is moderate to high depending on the speed Blueair Pro L is running. At max speed the air purifier does drain a fair share amount of electricity especially if you are running 24x7. We recommend purchasing the addon Air Intelligence Module to enable Auto mode for better energy management.

^ Blueair Pro L replacement filters estimated cost
An exceptional air purifier, Blueair Pro L is very expensive for home use and that is excluding addon cost for the optional Air Intelligence Module. Annual filter replacement cost is also skyrocket high (double filters for both Particle and SmokeStop) where you could buy at least 2 decent brand new air purifier. Office use Blueair Pro L is perfectly fine but it's simply too expensive for average joe like us.
