A HEPA filter is a filter that can trap almost a hundred percent of particles from the air in your home, and HEPA stands for High Efficiency Particulate Air, and it’s used to describe an air filter that can trap 99.97 percent of particles in the air.
Most HEPA filters are made of interlaced glass fibers, but the glass fibers are twisted and turned in every direction and as particles are sucked into the air filter, they travel through this web.
That means they get trapped in the web and taken out of the HVAC ducts and ventilation ducts in your home, however using a HEPA filter in your air conditioning plan or your heating plan will really improve the air quality in your home. And don’t worry about the particles that make it through the HEPA filter in your Heating and A/C system. It’s not like those particles are going to go straight into your nose and respiratory tract. There are other technologies, such as activated carbon filters, that work in air purification systems to help trap other things that a HEPA filter might miss. HEPA air filters were originally made to be used in factory settings but today, they are being used in lots of different sites where you might find an air filter. HEPA filters are even being used in car air filters and heating and cooling systems, in high quality vacuums, and in most air purification systems. If you’re concerned about the air quality in your home and you’re thinking of trying to make some improvements, entirely spend the extra cash to buy HEPA filters for your heating and cooling system, and while you’re at it, buy an air purifier with a HEPA filter too. They are completely worth the extra cash you have to spend up front.
