The high-efficiency particulate arrestant technology deemed the HEPASilent™ is the biggest eye-catcher of the Classic family.

The combination of electrostatic and mechanical filtration gives an additional edge to the purifier over the rest.

The voice control is another Classic feature that lets you remotely operate the air purifier and adjust the settings or turn it on/off as per convenience.

This is much more user-friendly that a remote or app or buttons on the purifier body as you can control the actions by just speaking out!


What All Impurities Blueair Classic 205 Removes

The standard particle filter used by the Blueair Classic 205 air purifier clears all kinds of impurities present in the indoor air down to 0.1-micron size.

This includes common allergy triggers like pollen from flowers and trees. The more significant contaminants include dust, dust mites, mold spores, hair, pet dander, etc.

The gaseous pollutants include industrial emissions, benzene, toluene, NO2, TVOCs, formaldehyde, cigarette smoke, vehicle emissions, cooking odors, perspiration, etc.

The activated carbon layer of the Blueair filter can easily remove these with its excellent adsorption capabilities.

All of these impurities are removed with an efficiency of 99.97% to deliver clean, germ-free air !

Can Blueair Classic 205 Remove Viruses ?

Internal testing conducted by Blueair concluded that the Classic family, including the 205 models, is effective in 99% removal of germs.

This indicates that the Blueair Classic 205 air purifier not only removes viruses, but it also leaves these viruses unviable i.e., unable to reproduce.

Blueair Classic 205 Air Filter Systems: How It Purifies Air

The whisper-quiet fan of the Blueair Classic 205 air purifier draws in air from all corners of the room.

Upon entering the purifier system, the particulate matter in the air is treated to an electrostatic charge, after which the air proceeds to interact with the Blueair filter.

The Blueair filter is composed of several ultra-thin polypropylene fibers of various sizes in many different layers.

These electrostatically charged particles cling to these interlocking fibers and get trapped like magnets. Once locked in, these will not get released back into the air.

The benefit of using polypropylene in the purifier is twofold. Not only does it form an excellent trap for most impurities, but it is also antibacterial in nature, restricting further growth of germs.

It is also an environmentally responsible choice.

The remaining clean air passes through the thin filters with relative ease. The less-dense filter of the air purifier means that the air purifier needs less energy and pressure.

It also reduces clogging, which is a common problem encountered in other models.

Ultimately, the clean air is circulated through the room with an impressive CADR !

Price of Blueair Classic 205 and Its Filters

Although the Blueair name is quite the premium brand in terms of air purifiers, the Classic 2015 is a reasonably cost-effective option in its product range.

The product is pricier than its counterparts in a similar coverage area range. However, it also offers features that the other brand air purifiers don’t have.

The replacement filters are priced similarly to other replacement filters in the market.

Overall, the Blueair Classic 205 is a good purchase for someone looking or a reliable, long-lasting model!

Why We Like It

We like Blueair products for their well-found balance between style and technology.

The sleek body houses an efficient purification system that, at its lowest settings, consumes less power than a light bulb.

You can comfortably sit in one corner of the room and shout out commands that will let you modify the air purifier settings with ease.
