If this dust and bacteria were to make its way through, it would be flowing around in your air, which you would then be breathing in.
Have you ever wondered how those HEPA filters catch all the things they manage to catch? I have always wondered how they are able to keep your air quality so clean. I know they work really well, however how exactly do they work? This was a question I asked our local heating and AC serviceman when she came out to repair an air conditioning concern I was having. I told her that I had recently switched to HEPA filters because of how good they are in the home. She went on to explain to myself and others exactly how the HEPA filter works. She said that they have a bunch of microscopic fibers and that they are responsible for catching all the dirt and debris. These papers are so small that they are able to catch even the tiniest pieces of bacteria and particles that would otherwise definitely make her way through. If this dust and bacteria were to make its way through, it would be flowing around in your air, which you would then be breathing in. However, the HEPA filter stops them and it prevents them from getting into the air. Therefore it helps to keep you healthy, which is why there are more than 2 benefits to using a HEPA filter. When she explained this to myself and others it all made sense and I understood how HEPA filters work and I was pretty amazed by the technology. It was really nice to have a HEPA filter to use because they really did offer myself and others great air quality.
