HEPA filters, in particular, are excellent for effectively reducing particles such as dust mites, pet dander, pollen and mold spores. If you're concerned about these types of particles in your home, upgrading your air filters will help protect your family. Yes, by using HEPA filters in both vacuums and air purifiers, the user can reduce the amount of airborne allergens and contaminants in a home. Never buy air purifiers that generate ozone.
According to the EPA and doctors, ozone is a respiratory irritant and, in fact, can worsen allergy or asthma symptoms. Air purifiers are a safe way to improve indoor air quality. In general, they do not emit harmful chemicals or gases into the air. Nowadays, we spend most of our time indoors, where the air is usually more polluted than outside.
Air purifiers clean the air of particles, improving air quality and reducing health risks. The three most common appliances that use HEPA filters are whole-house filtration systems designed to treat complete air conditioning systems, portable air purifiers and vacuums. To understand how HEPA filters work, consider them as a dense forest of entangled fibers pressed into a sheet. A HEPA filter component that is part of an air purification system is a good way to remove particles such as pet dander, pollen, smoke and the dust.
In fact, EPA agents warn that the functionality of air purifiers is limited in terms of filtering gases and that filters must be replaced frequently for optimal operation, usually every three months. If you're concerned about larger particles, such as dust, pollen and animal dander, an air filter with a HEPA component will help reduce them in the air. In the same way, higher-quality filters will prevent more garbage from passing through the system than lower-quality filters. Users should not assume that an air purifier equipped with a HEPA filter will fully protect them against infection. While most allergenic particles are large enough to be trapped by a HEPA filter, very small fragments can penetrate the filter and remain in the air.
With the goal of controlling COVID-19 and reducing airborne transmission rates, air purifiers equipped with HEPA filters can play an important role when used in homes and public environments, such as waiting rooms. Air purifiers using HEPA filters can capture SARS-CoV-2 particles. The virus that spreads COVID-19. The HEPA filter should only be understood as part of the solution for improving indoor air quality. For example, a HEPA filter, which can trap up to 99.97% of particles, will cost more than a flat filter.
Now, almost all HEPA filters are combined with additional filtration technologies, such as activated carbon. A HEPA filter with the label “True HEPA” or “Absolute HEPA” has been tested and meets the criteria to be highly efficient. In the 1960s, HEPA filters were used in hospitals to help stop the spread of germs and particles in the air, and soon after, they began to appear in appliances, such as vacuums, air purifiers, and whole-house air filtration systems. A whole-house HEPA air purifier connects to the main trunk of the intake duct of the house's heating, ventilation and air conditioning systems and filters harmful contaminants every time the boiler or air conditioner are in operation.
