What is the Difference Between HEPA Filter and Air Filter?

HEPA stands for High-Efficiency Particulate Air (filter or filtration). A true HEPA product is an air filter that can trap even the tiniest particles, with an efficiency of 99.97 percent. This is effective enough to remove most particles from the air. An ion purifier is a good, low-cost solution for general air cleaning, especially if viruses and VOCs (Volatile Organic Compounds) are a problem.

However, for those with respiratory problems or conditions, a HEPA purifier will provide maximum effectiveness. Air Health offers many solutions, including the SKYE air purifier with HEPA filter and UVC light, to provide your family with clean indoor air and peace of mind. Both filters use layers of dense fibers to create a fine-mesh filter that removes contaminants as air passes through them. Ultra-low particulate air filters (ULPA) and HEPA filters are used in commercial air filtration systems to trap extremely small polluting particles. Although they do not remove as high a percentage of airborne particulates as HEPA filters, higher-efficiency standard air filters can significantly improve indoor air quality and, at the same time, protect air conditioning equipment. HEPA and ULPA filters are designed for use in a variety of applications, such as industrial vacuums to remove asbestos, remove toner dust from office equipment, prevent the spread of airborne bacteria in surgical operating rooms, and other crucial medical air filtration applications.

ULPA filters usually pass 20 to 50% less air than HEPA filters, which means that the room has fewer air changes per hour. Some HEPA filters come with antimicrobial coatings so that mold spores don't reproduce inside the filter and further contaminate the home. HEPA filters can be more expensive, although their operation offers advantages that can offset those costs, depending on your budget and needs. These complex HEPA filters exceed the typical MERV rating scale, making them the most effective and popular choice for many industries. True HEPA filters cannot be used in conventional forced air heating and cooling systems without making major modifications to the equipment. HEPA air purifiers with carbon help filter out the smallest contaminants, as well as fumes, smoke, and other odors.

HEPA filters are particularly effective at eliminating odors, as well as the smallest particles of dust and contaminants.
