This is a topic that everyone is very concerned about, can the air purifier filter out viruses? In addition to wearing facemask to prevent the inhalation of viruses, bacteria and droplets, what else can we do to ensure the inhaled indoor air is safer and cleaner?
As of today, believe there is only one solution in the market and that is – the air purifier.
The air purifier can filter out the harmful airborne substances and reduces the health risk caused by inhalation.
So far, there are mainly 2 types of air purifiers in the market. The basic air purifier works with a fan and filter while the more advanced model is equipped with sterilisation and disinfection functions.
The basic air purifier is not able to sterilize and disinfect, but the one with sterilisation and disinfection functions has better performance in filtering, purifying, sterilising and disinfecting the airborne particles.
Air purifier with sterilization and disinfection functions meets the following requirements:
- 1. HEPA Filter Grade
H13 HEPA filter is a highly efficient medical grade filter with 99.97% filtration efficiency, can effectively filter and remove ultra-fine particles as small as 0.3 microns, including the airborne PM2.5 particles, bacteria, pollen, mould spores, dust mites, airborne pollutants, particles and droplets that are attached with bacteria or coronavirus, and allergens. - UV Light
UV light with the wavelength below 280nm is able to sterilize and disinfect bacteria and viruses, inhibit their activities and prevent their production and reproduction. - Activated Carbon Filter
Able to absorb harmful gases (TVOC) and invisible particles, such as harmful substances released by building materials, wall paint, furniture, cleaning agents, as well as air pollutants and unpleasant odours, achieving the effect of purifying the air. - Photocatalyst Filter
Effectively trap and degrade indoor TVOC such as formaldehyde, toluene, xylene, etc and render the substances harmless when energized with UV light, achieving the air purifying effect.
A researcher of the Institute of Environmental and Health-Related Product Safety of the Chinese Center for Disease Control and Prevention, also an expert in the field of environment and health, said that air purifiers with high efficiency HEPA filter graded H12 and above can filter out aerosols and droplets with viruses.
Choose an air purifier with negative ions function
Benefits of negative ions are well-known, they are named “vitamin of the air” by the experts. Using an air purifier with negative ions function indoor, can give you the natural atmosphere with high concentration of negative ions, similar to those in the forest, mountain and waterfall. You get to enjoy the purified air while breathing in the goodness of negative ions to enhance your physical and mental health.
Medical research has shown that negative ions in the air can increase the oxygen content in the blood, help promote human cell metabolism, improve human immunity, and enhance and regulate human muscle energy. At the same time, it can improve nasal diseases, sleep, heart and lung
functions, and has obvious health care effects on more than 10 major human body systems!
The rule of thumb is, ensuring the proper indoor air circulation will reduce the concentration of viruses in the air. But some indoor spaces have limitation in proper ventilation or getting enough good air to refresh the polluted indoor air.
Beyond doubt, installing an air purifier with sterilisation and disinfection function, with proper use, is an extra shield of protection to improve and purify indoor air quality.
