Effective Contaminant Filtration
The Blue Pure 221 excels at removing a wide range of pollutants from the surrounding air supply, and it can effectively trap particles down to 0.1 microns in size.
Therefore, it reduces the pollution levels of many common contaminants, including:
- PM1, PM2.5 and PM10 particles
- Dust, pet dander, pollen and mould
- Odours, smoke and VOC’s (Volatile Organic Compounds)
- Bacteria and viruses
Advanced Three-Stage Filter
To remove so many pollutants, the Blue Pure 221 uses a three-stage method that starts with a pre-filter and ends with Blueair’s unique HEPASilent Combination filter.
- Pre-Filter - Captures large dust particles and hairs to ensure optimal usage of inner filter layers.
- HEPASilent Combination Filter - Combines particle and carbon filtration together to remove 99.97% of particles such as dust, pollen, mould and spores alongside odours and smoke.
For best results, Blueair recommends cleaning the pre-filter regularly and replacing the HEPASilent Combination filter every 6 months.
Additionally, the HEPASilent technology has been independently tested at RISE (Research Institutes of Sweden) to achieve the HEPA H13 filtration grade according to standard EN-1822.
High Clean Air Delivery Rate
Rounding out the filtration package offered by the 221 is the ability to alter the fan speed. There are a total of three settings available, and the highest level, “3”, offers the best filtration performance.
When used on the “3” setting, the Blue Pure 221 can produce CADR’s of:
- Pollen CADR: 590 m3/h
- Dust CADR: 590 m3/h
- Smoke CADR: 590 m3/h
Additionally, in rooms sized 50 m², it can complete five full air changes in an hour. A feat that is aided by its 360° air intake design.
Quiet & Efficient
Beyond its exceptional performance, the Blue Pure 221 is quiet when active, and its HEPASilent filter produces 10% less noise than traditional HEPA filters.
While operating at its lowest fan speed, it only produces 31 dB of noise. That’s equivalent to the sound of whispering, making it suitable for use at night time.
Matching those quiet noise levels, the 221 is also very power efficient. When active, it only requires a maximum of 61 watts of power. As a result, it’s cheap to run, even for extended periods.
Certified Allergenic Relief
Lastly, the Blueair Blue Pure 221 is certified by multiple industry bodies, including AHAM (Association of Home Appliance Manufacturers and Energy Star.
Therefore, it is proven to alleviate symptoms caused by strong allergies to airborne particles such as dust or pollen.
It has also been independently reviewed by experts at Consumer Reports, which has earned it a recommendation as one of the top air purifiers around.
