Design And Usability
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.

Filters And Performance
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.Noise And Energy Usage

Blueair Pro L VS The Challengers

Blueair Pro XL
You are already in for the best, why not go for the absolute best money could offer?
Blueair 605
Same filtration setup with equally impressive performance. Also comes with Wi-Fi support along with timer (via app).Pros
- Exceptional dust, pollen CADR while Smoke CADR is at top tier either.
- Wide purifying coverage supported by strong and consistent airflow delivery.
- HEPASilent Technology that electrostatically charge all incoming particles.
- Twice as efficient with 2 high grade Pro Particle filter and 2 Pro SmokeStop Filter.
- Lower than average noise level given how strong the airflow delivery is.
- Up to 5 years warranty.
Cons
- Very expensive to own and maintain (double filters setup).
- No timer, no Wi-Fi support and no remote control.
- No permanent pre-filter that helps protect and extend other filters lifespan.
- Air Intelligence Module does not comes as standard (require for air quality monitoring and Auto mode).
