What is the Difference Between HEPA Filters and Air Purifiers?

HEPA filters are one of the most efficient air purification technologies available, removing more particles from the air than ionic air purifiers. The main benefit of using a HEPA air purifier is that they become more efficient as they get dirty, meaning that a dirty filter can remove more particles than a clean one. HEPA air purifiers are designed to circulate air in the room and trap contaminants, dust, allergens and more in their filters. Unlike ionic purifiers, HEPA purifiers always use a fan, making them louder than ionic purifiers.

For air cleaning performance, HEPA filters are the best technology, removing most airborne contaminants and the most dangerous particles. In addition, HEPA filters become more efficient over time, taking off more with use. Noise level is another factor to consider when comparing HEPA air purifiers and ionic air purifiers. HEPA air purifiers are designed to circulate air in the room and remove contaminants, dust and allergens by trapping them in filters. Ionic air purifiers usually don't have a fan, so they're quieter. A HEPA-type filter is a lower version of True HEPA.

Unfortunately, because of the trademark, a HEPA-type filter can be sold under the guise of misleading consumers into believing that the HEPA type is close to or as effective as True HEPA. Air filters filter the air (HEPA air filters, for example), while air purifiers disinfect the air by emitting negative ions, ozone, using heat (Airfree air purifiers) or with UV or UVC lamps. Air ionizers release negatively charged ions into the air and bind to dirty particles, causing them to become too heavy to float. Both types of air purifiers are used to capture airborne droplets of SARS-CoV-2, which is crucial to stopping the spread of Covid-19. To provide the cleanest and safest air, it's important to choose a technology backed by testing and proven effectiveness. When comparing an air cleaner to a HEPA air cleaner, the air cleaner works similarly to a HEPA air cleaner but picks up contaminants using electrically charged plates.

Products that include a collection dish or that are placed in a neutral location are best to prevent the possibility of particles coming back into the air when people walk around the room. There are many different filters available but the air quality will still be poor if the filter lets in too many particles. When it comes to choosing an air purifier for our home or office, there is a lot of conflicting information. Fortunately, ionic air purifiers and HEPA filters work very differently, allowing you to choose the one that works best for you. Ionic purifiers are much cheaper to own in the long run with lower energy consumption and no need for filter replacements.
