Viruses can be transmitted in many ways through touch, saliva, and even the air. Despite having alcohol to kill 99% of the viruses, an air purifier can do the same, by filtering out any virus-sized particles in the air.
Most of us understand that an air purifier is made up of a fan and a filter. The filter, especially a HEPA filter, makes an air purifier effective. The HEPA filter removes up to 99.97% of airborne pollutant particles which are as small as 0.3 microns.
With the recent outbreak of the coronavirus (COVID-19), which are highly infectious but less deadly than Severe Acute Respiratory Syndrome (SARS). This virus can be transmitted through droplets of an ‘infected’ person’s cough or sneeze and these particles are smaller than 2.5 microns, which are bigger than some dust particles and gases.
Can the HEPA filter of an air purifier capture these particles?
HEPA filters are made of a series of fibers which is mainly composed of fiberglass with a diameter between 0.5 and 2.0 microns. HEPA filters have definitely a higher chance of capturing the virus such as the dust, allergens, bacteria and mold spores. These can be destroyed with the supplement of an Ultraviolet (UV) treatment which is built-in together with the filter.
If you are living in a shared room or house or working in an enclosed environment with many people, by turning on the air purifier it can help to reduce the chance of transmission, as the HEPA filter will likely to filter out 99% of the COVID-19.
Whether with the existence of the COVID-19 virus, other common airborne diseases such as colds and flu are commonly found around. An indoors and/or enclosed premises can be 5 times more polluted than outdoor air. Indoor pollutants are generated from the cooking residues, furniture, cleaning hygiene and people. These will result stagnant air and unpleasant smell circulating around; hence, an air purifier is able to purify and filter the unhealthy air, virus, and bacteria for a clean air.
You do not need to look far to get an ideal air purifier. Aztech air purifiers come in different sizes and purification stages, for 45m2 and 60m2 purifiers with 7 purification stages and our flagship model of 80m2 with 8 purification stages. All of these air purifiers are inclusive of HEPA with an ultraviolet (UV) sterilizing built-in filter. If you can’t decide, here are some tips on choosing the right air purifier.
