A HEPA filter is a filter that can trap almost a hundred percent of particles from the air in your home, HEPA stands for High Efficiency Particulate Air.
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. The glass fibers are twisted and turned in many directions 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, using a HEPA filter in your air conditioning unit or your heating system will greatly improve the indoor air quality in your home, and don’t worry about the particles that make it through the HEPA filter in your HVAC 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 purifiers to help trap other things that a HEPA filter might miss. HEPA air filters were originally made to be used in factory settings but nowadays, they are being used in lots of unusual places where you might find an air filter. HEPA filters are even being used in vehicle air filters and heating and cooling systems, in high quality vacuums, and in most home air purifiers. If you’re worried about the indoor air quality in your house and you’re thinking of trying to make some improvements, spend the extra cash to buy HEPA filters for your heating plus cooling system. While you’re at it, buy a whole home air purification system with a HEPA filter too. They are truly worth the extra cash you have to spend up front.
