There are two basic types of air purifiers: filters and sanitisers. The filter type works by removing contaminants, such as dust, mites, pollen or dander from the air, while the sanitiser kills viruses, moulds or fungi that might be circulating in the air. Both types of purifiers are effective in improving indoor air quality and reducing the transmission of coronaviruses.<\/span><\/p>\n

<\/span>What to Look for in an Air Purifier<\/b><\/span><\/h2>\n

<\/span>CADR (Clean Air Delivery Rating)<\/b><\/span><\/h2>\n

This is a measurement of the cleaning performance of a purifier. The rating reflects the cleaning speed of the purifier, and it is measured through the volume of air per cubic feet per minute. A CADR in the range of 300-350 is great for a small indoor space.\u00a0<\/span><\/p>\n

<\/span>HEPA certified<\/b><\/span><\/h2>\n

Only HEPA certified purifiers have the ability to remove ultra-fine particles. Look for the specifications of an air purifier, such as the standard 99.97%. Air purifiers with labels like \u2018HEPA-type filters\u2019 are not true HEPA.\u00a0<\/span><\/p>\n

Moreover, a true HEPA purifier can filter particles as small as 0.3 microns, with MERV (Minimum Efficiency Reporting Values) between 17 and 20. True HEPA purifiers cost more than the usual HEPA-type ones because of their higher filtration efficiency.\u00a0<\/span><\/p>\n

<\/span>Size<\/b><\/span><\/h2>\n

To effectively filter air indoors, you choose the right size air purifier. It will not do a good job of filtering the air when the unit you choose is too small and under-powered.\u00a0<\/span><\/p>\n

Basically, there are four sizes available in the market. The small size is good for a small room of up to 200 sqm. The medium size can cater to rooms with a 200-400 sqm floor area, while large ones can accommodate rooms that are 400-1,500 sqm in size. You can also opt to get the whole house unit covered to filter the air in every room of your residence.\u00a0\u00a0<\/span><\/p>\n

<\/span>Conclusion<\/b><\/span><\/h2>\n

HEPA air purifiers are effective in reducing not only the transmission of coronaviruses but also other respiratory issues, such as asthma and sinusitis. Air purifiers can help reduce the risk of transmission by trapping viruses that are lingering in the air. However, it should not be used as the main defence against coronavirus. Protection against this infectious disease requires layers of protection like frequent handwashing, wearing of a mask and social distancing. <\/span><\/p>\n","protected":false},"excerpt":{"rendered":"
