Unique Blueair HEPASilent Technology
The new Classic 405 uses Blueair's patented HEPASilent Technology to remove virtually all airborne pollutants in medium size rooms up to 40m2. Using the best in electrostatic and mechanical filtration, the HEPASilent Technology is a revolutionary combination of advanced filter media and an encapsulated particle-charging chamber. This ensures that your Blueair purifier delivers results far superior than either mechanical or electrostatic technology alone.

Removes more of the most harmful pollutants than standard Hepa filters.
Theuniquedesign enables all Blueair purifiers to achieve 99.97% filtration efficiency, all the way down to .01 micron. Most Hepa filters only trap particles down to 0.3 micron. The smaller particles trapped by the Blueair technology mean that your room will be continually protected from much more of the most hazardous smaller particles like viruses and bacteria than it would be with basic hepa filtration.

In touch with your clean air.
Touch sensitive easy-to-read LED icons let you see the status of your air purifier’s Wi-Fi connection, operating speed and filter status. Adjusting operation is simple, Just touch. Downloading the free Blueair Friend app will also enable you to control the new Classic via WiFi from afar using any smart device. (Don't worry if you are not interested in the WiFi functionality, the 405 can also be fully controlled using only the LED Icons on the top of the machine!)

Want to see even more detailed information on your indoor air quality?
Linking your Classic 405 to the optional Blueair Aware monitor via Wifi will also enable you to see detailed information about your actual indoor air quality on your smart device app and access outdoor air quality data in real time in most major urban areas too. Alternatively, consider the Classic 480i model which has this feature and air quality sensors already built-in as standard.

Quiet Performance.
A perfect choice for medium to large rooms, the Classic 405 packs quite a punch, cleaning the air in rooms up to 40m2 up to five times an hour ( that's one complete air change every twelve minutes). The unit is also extremely quiet in operation. Although its lowest in class noise levels make it ideal for bedrooms, it is also perfect for other living areas areas and work spaces to get rid of airborne pollutants like allergens, pollen,dust, smoke, traffic pollution and mold spores.

Power and Economy
The union of visually pleasing form and effective function has long been a hallmark of Swedish design, and the new Classic air purifier range is no exception. The 405 is designed for maximum performance, however it is also Energy Star Qualified ensuring it consumes minimal electricity in day to day running. The design is not only attractive but also built to last. Each machine is finely crafted from galvanized steel and is powder coated for durability and environmental protection that produces no chemical off gassing. The air purifier housing is easy to clean, and won't pick up grime and oily stains the way that many plastic units can and each machine comes with a full 5 year Warranty.

Is Blueair as good as HEPA?

Example: All Blueair units are HEPA air purifiers. That means they remove more than 99.97% of the smallest airborne air pollutants down to 0.3 microns in size. ... 1. Blueair Blue Pure 211 Review (Overall Best Blueair Air Purifier).

Is Blueair a good air filter?

The Blueair Blue Pure 411 places second in our rating of the Best Air Purifiers for Small Rooms and ninth in our Best Air Purifiers of 2022 rating overall. At $119.99, it has a price that fits many budgets. The unit cleans rooms of up to 161 square feet, and its CADR ratings are 120 for smoke, dust, and pollen.

Does Blueair use true HEPA filters?

Neither Blueair model is rated as true HEPA, but they are certified by AHAM to have clean air delivery rates (CADR) of 350 and 250, respectively, and they performed exceptionally well in our testing, in which we measure each purifier's effectiveness at capturing HEPA-standard 0.3-micron particles.

Is Blueair Healthprotect worth?

Very informative and user-friendly app that makes it easy to monitor air quality both in real time and afterwards. The app also allows you to track changes in the air outdoors. It costs a lot of money and is quite conspicuous, which can be a problem for interior design aficionados.
