The COVID-19 pandemic is upsetting our lives, so it’s no surprise if you think more about the air around you. But what can we do to improve it? Does the HEPA filter permanently remove the virus? Here we find.
Did you know that the levels of pollutants in your home’s air are twice as high as outdoors, according to the Environmental Protection Agency (?EPA)? In addition to avoiding external triggers, if you have allergies, you also need to deliberately eliminate indoor aerial allergens.
High-efficiency particulate air filters (HEPA) need to remove indoor dust, pet dander, mold, and other airborne particles that can exacerbate respiratory allergies and asthma attacks. This type of filter is usually included in premium air purifiers, but not all.
But what is a HEPA filter? Why do you need them? Live Science has asked primary care physician Dr. Christopher Oseh to explain everything.
What is a HEPA filter?
HEPA filter, which is an abbreviation for high-efficiency fine particle air filter, is a mechanical filter designed to remove airborne particles such as indoor microorganisms, dust, pollen, and pet skin dust. HEPA filters are intended to improve air quality by providing a mesh screen and a high density filter to trap particles in the air. These HEPA filters can remove small suspended particles as small as 0.3 microns in size. EPA..
HEPA filters come in a variety of sizes and capacities. Therefore, it is imperative to purchase a filter that has the ability to filter air of a particular room size.
Some air purifiers have a built-in HEPA filter, which, unlike those without a HEPA filter, have additional filtration capacity to improve the quality of the air distributed indoors.
To optimize the efficiency of HEPA filters, mechanical filters require regular cleaning or replacement for maximum functionality. Cleaning or replacement of HEPA filters should be done more frequently during allergic seasons with high pollen counts and high airborne particles. For the rest of the year, it can be cleaned or replaced quarterly.
Does the HEPA filter completely remove the virus?
Few studies have shown that HEPA filters can completely remove viruses in the air, but they can be useful. The infectious virus that causes respiratory illness may float directly in the air or be surrounded by respiratory droplets released when an infected person coughs or sneezes. If the virus is in a droplet, the size of the droplet in the air will be large and can be easily removed with a HEPA filter.
Study from University of Castilla-Lamancha We have clarified the effectiveness of HEPA filters in the removal of aerosols containing the COVID-19 virus. Researchers have discovered that a HEPA filter added to the air purification system filters virus-containing aerosols. However, it is very important to note that the sample size for this study was relatively small due to its statistical significance. This indicates that more extensive studies using large sample sizes are needed to conclude the role of HEPA filters in the removal of non-aerosolized viruses, removing COVID-19 from the environment. It is not recommended to rely on this method for this reason.
Do HEPA filters help with allergies?
HEPA filters reduce the frequency of allergens and relieve symptoms by removing particles in the indoor air that trigger allergies in sensitive individuals.
HEPA filters are ideal for respiratory allergies such as mold, pollen, dust and pet dander. This is because these allergens are floating in the air. HEPA filters help remove these respiratory allergens from the air and improve indoor air quality.
Research conducted to confirm Effectiveness of air purifiers with HEPA filters There was a significant improvement in the symptoms of allergic rhinitis among the participants. The HEPA filter of the air purifier effectively reduced the concentration of house dust mite and particulate allergen, which are one of the main causative agents of allergic rhinitis.
How to choose a HEPA filter
Before purchasing a HEPA filter, consider the type of particles you want to remove in the room, the size of the room, and the Clean Air Delivery Rate (CADR).
If you want to filter smaller air particles, make sure that the HEPA filter has the ability to filter micro and nano size particles. If you have a large room, you can filter a larger percentage of the air, so choose a HEPA filter that has a higher supply of clean air.
Definitive research on the ability of HEPA filters to remove viruses is limited. Nevertheless, some studies have shown that HEPA filters can remove viruses surrounded by several droplets and viruses with a diameter larger than the mesh pores of the HEPA filter. However, extensive research should be conducted before it is safe to recommend the use of HEPA filters to protect against airborne viruses.
However, HEPA filters help remove indoor allergens that cause respiratory allergies, improving the quality of indoor air distribution at home and in the office and providing a better environment for allergen-sensitive people to stay. Helps to provide.
With all this in mind, it’s important to choose an air purifier large enough for the room you want to use. An air purifier that is too small is of little use.
