Viruses such as the novel coronavirus that causes COVID-19 often attach themselves to dust or droplets, and a good air purifier with a HEPA filter can help capture them.Īll HEPA filters are supposed to remove at least 99.97 per cent of dust, pollen, mold, bacteria and airborne particles. You still need masks, hand-washing and physical distancing to keep the virus at bay.Ī HEPA (high efficiency particulate air) filter is a key part of the equation, too. However Siegel warns all of those things are not enough on their own to protect your family from COVID-19. (Anu Singh/CBC)īut air purifiers need to be efficient and sized appropriately for the space they are in. Jeffrey Siegel is a professor of civil engineering at the University of Toronto who has been studying indoor air quality for over 20 years. Siegel said a good air purifier can also help clear out coronavirus particles and reduce the air's viral load. Working with Siegel and his team, Marketplace put five popular brands to the test: the Levoit LV-H132, GermGuardian AC5350B, Dyson Pure Hot + Cool, BlueAir Blue Pure 211+ and the Honeywell HPA 160, as well as a DIY box fan with an added filter.Īir purifier sales in Canada jumped nine per cent in 2020 compared to pre-pandemic 2019, totalling $136 million, according to statistics from market research firm Euromonitor. University of Toronto engineering professor Jeffrey Siegel, a leading expert on ventilation, filtration and indoor air quality, calls it "a marketing jungle." There are plenty of claims for consumers to wade through: "the only air purifier, heater and fan to clean a whole room properly " "UV-C light killing germs " and "true HEPA filter" are just some of the promises Marketplace investigated. Popular air purifier brands are making a lot of promises about what they can do to keep your home safe, but a CBC Marketplace investigation found that a homemade DIY purifier can actually outperform some of the most well-known brands on the market. Its colour can also be modified through optional pre-filter accessories.Clean indoor air is increasingly important as COVID-19 keeps Canadians inside. Built to be compact, it has a minimal form factor, which has been blended with clean and modern styling ideas to great success.
Moving beyond its technical elements, the Blue Pure 411 also makes an impact with its bold and colourful design. This single button is used to cycle between the 3 speed settings and even indicates when the filter cartridge should be removed and replaced. It’s streamlined interface consists of just one button on the top of the unit. Tutorial Videoīeyond its impressive purification ability, the Blue Pure 411 is also very easy to control. The complex nature of this structure also prevents allergens from escaping back into the surrounding environment once they are captured. The Combination filter used in the Blue Pure 411 also implements a gradient structure of ultrasonically bonded fibres, which allows for maximum airflow to be maintained while allergens are removed. Therefore, this purifier is a great nighttime companion that is almost undetectable. When at its lowest level it can even operate at 17 dB, which is about the same as standard breathing in terms of volume. That efficiency also allows the Blue Pure 411 to remain very quiet when in operation. As a result, at its highest level, it only uses 10 watts of power and at its lowest level, it works at a mere 1.5 watts. To match the top purification quality offered by the 411, Blueair has worked hard to make it very efficient when in operation. As a result, the Combination filter doesn’t need replacing too frequently and it can be easily to disposed of as it is widely recycled. Its 99.7% effectiveness against allergens allows it to make a notable difference very quickly and it has an expected life of 6 months or around 4,380 hours of use. This includes pollen, dust, PM 2.5, pet dander, smoke, mould, bacteria and viruses. Built to combine both HEPA and Activated Carbon filtration it is effective against many different contaminants and allergens. The Combination filter used in the Blue Pure 411 marks the current peak for air filtration technology.
Designed to be compact while still providing top air filtration performance, the Blueair Blue Pure 411 is an ideal purification solution for rooms as large as 15 m².
