The smallest and lightest Wi-Fi ready air purifier in its Classic stable, Blueair 205 stands at 17 x 21 x 8 in (43.2 x 53.3 x 20.3 cm) size with 24 lb (10.9 kg) in weight. Made from galvanized steel that guarantees no chemicals off gassing unlike most plastic materials, Blueair 205 has one of the best build quality around and is exceedingly durable. Best of all you can fully recycle Blueair 205 when it reaches its lifespan.

Like all Classic models, Blueair 205 has 2 ways of controlling the air purifier however we will focus on the second method later on. The first and most common way is using the main buttons via its top control panel. You can control the fan speed, connect to your Wi-Fi devices and check filter status.

To further elaborate, let’s start with the fan speed button, 1 blue bar will light up if you are in first speed, 2 blue bar for second speed and so on. For the Wi-Fi button, the LED blue light will continue to blink if is ready to connect and stays blue if is connected. Finally for the filter button, LED icon will light up in grey + blue by default and change to orange when replacement filter is needed. To reset the filter button, simply hold the button for around 5 seconds.

Other standard features you would find in Blueair 205 include a 3-stage filtration with HEPASilent Technology, 3 speed, smartphone integration, filter replacement with no screws needed, filter replacement indicator, zero ozone emission, CARB certified, ENERGY STAR rated and 5 years warranty.

Blueair Friend app

Available in both Android and iOS, first you have to download/ install Blueair Friend app and include Blueair 205 into the app list. Once everything is in order, you could adjust the fan speed, LED brightness intensity, setup timer, enable/ disable child lock, night mode and finally advanced scheduling for speed/ LED based on either hours or days.

If you have the optional Blueair Aware monitor, you can also enable Auto mode for autonomous operation and monitor room air quality based on your various indoor activities.

While both Blueair 405 and 605 has excellent purifying coverage, Blueair 205 on the other hand has a moderate purifying coverage catered for medium size room. At 280 sq. ft. applicable area (5 air charges per hour), Blueair 205 would be best suited for bedroom or any room size that does not exceed the recommended coverage. The 3 speed airflow delivery is consistent with air coming in from bottom, back and side of the air purifier.

Blueair 205 technologies
HEPASilent Technology
All Classic air purifier utilize the same HEPASilent technology that promises 99.97% efficiency filtration rate against particles as small as 0.1 micron. No exception with Blueair 205 as it combines electrostatic and mechanical filtration where all incoming particles will be electrostatically charge. With all particles charged, pollutants like pollen, mold dust mites will be more clingy to the filters thus reducing the chances of these particles from getting away. Same theory would applied to the SmokeStop filter where it will focus on chemicals, smoke and odors instead. Additionally, The filters is designed in gradient structure and thermally bonded which further prevent particles from escaping even under heavy load circumstances. Another benefits of Blueair 205 filter is it uses natural anti-bacterial polypropylene fibers which is incidentally waterproof. Bacteria and mold would be inhibit from growth as these microorganism require water to thrive. Finally Blueair 205 would also slightly reduce surrounding ozone level by releasing cleaner and less ozone concentrated air.
