Frequently Asked Questions
Are Smart Air purifiers better than other air purifiers?
Smart Air purifiers use the same cleaning principle as most other air purifiers. The technology behind air purifiers is not complex, and readily available.
However, Smart Air is the only air purifier company committed to transparent communication through open data. We avoid overcomplicating our air purifiers with high markups and marketing gimmicks. Smart Air purifiers are honest, data-backed, and streamlined to do one thing: clean air.
Can Smart Air’s purifiers filter COVID-19?
HEPA filter air purifiers like Smart Air’s have been shown to filter out COVID-19 viruses, and lower transmission. View the CDC data on how HEPAs reduce COVID-19 transmission here.
What pollutants does the Blast Mini Mk II filter?
Smart Air purifiers’ HEPA filters capture many types of particulate air pollution, including nanoparticles as small as 5 nm (1/10th the size of the COVID-19 virus) to 30 µm (the size of pollen). The whole range includes viruses, bacteria, PM2.5, PM10, pet allergens, dust, and mold.
An additional activated carbon filter can be added on top of the HEPA filter in all of Smart Air’s products. The carbon filters can absorb VOCs (Volatile Organic Compounds) such as formaldehyde, paint thinners, petroleum fuels, or dry cleaning agents. Carbon filters also remove odors.
Learn which filters you need in our in-depth guide on air purifier filters.
Where should I position my Blast Mini Mk II air purifier?
Smart Air tests show the position of an air purifier in a room does not matter, as long as 1) The air purifier is at least 6 inches (15 mm) away from the wall. 2) The air purifier is strong enough for the room it is in.
How to know when it is time to replace the Blast Mini Mk II’s HEPA filter?
We recommend replacing the Blast Mini Mk II filter every 7-14 months. But the truth is the exact time depends on many factors such as the number of hours used and local pollution levels. The most accurate way to determine when to replace a HEPA filter is to use an air quality monitor. Learn More: How to use an air quality monitor to test a HEPA filter
