As concern about indoor air pollutants grows, air purifiers are becoming increasingly popular. But with so many options on the market, it can be difficult to know which type of air filter is best for dust. The good news is that HEPA-filtered air purifiers are often the most effective for filtering dust from your space. According to the Environmental Protection Agency (EPA), HEPA filters can remove 99.97% of dust particles that measure 3 microns in diameter.
Air purifiers can be effective in removing dust indoors and improving asthma and allergy symptoms. In a whole-house system, dust and pollen particles are charged as they pass through the unit, and then captured on an oppositely charged collector plate. Portable ion filters, which operate without fans, send negative ion currents directly into the air. There are thousands of portable air purifiers that can help, but the best ambient air filter for dust is a HEPA filter.
Unlike household air filters for an HVAC system, highly efficient HEPA air filters work great in a standalone air purifier. For domestic use, a MERV 13 air filter offers the ideal balance between affordability, air purification and airflow. If you're considering a portable or whole-house electronic filter, check the product specifications to ensure that it does not exceed safe ozone emission levels. Carbon is the best option for volatile organic chemicals (VOCs) and odors, but it's also expensive and you'll need to replace it long before the HEPA filter needs to be replaced.
Some air filters are hybrids that combine both methods, and some include activated carbon elements to combat odor. Choosing the right type of HVAC air filter can make a big difference to the amount of dust in your home. For effective virus filtration, the EPA recommends air purifiers that can remove small particles ranging from 0.1 to 1 micron. If your home doesn't have air conditioning or central heating, portable air cleaners are the most practical option. When researching air purifiers, it's also important to consider units with no carbon components in their filters.
This air purifier comes with a HEPA filtration system and an activated carbon pre-filter, and is suitable for 465 m2. In conclusion, HEPA-filtered air purifiers are often the best for filtering dust from your space.
