Electrostatic filters are the most effective when it comes to capturing small particles. It's important to note that MERV and HEPA are two different types of air filters, although they are both commonly associated with air filtration. HEPA, which stands for High-Efficiency Particulate Air, is a highly absorbent media filter that meets HEPA standards. According to the European standard, a True HEPA filter will filter the air and capture at least 99.95% of particles 0.3 microns in size.
The U. S. Department of Energy (DOE) states that a True HEPA filter must capture at least 99.97% of particles of at least 0.3 microns in size. It circulates room air more than four times an hour and is equipped with a built-in smart filter replacement reminder and night light.
A HEPA filter is the ultimate solution for air filtration and far exceeds what a MERV 13 can do. There are several standards and test procedures that help show the efficiency with which air purifiers clean the air in a room. The initial cost of this type of air filter for HVAC systems is high, but it should be seen as an investment that will last for many years. The most common system for measuring the filtration capacity of an air filter is known as a MERV, or Minimum Efficiency Report Value.
The Bissell air purifier is equipped with Wi-Fi, allowing you to control it via the brand's app or monitor air quality when you're not at home. AHAM also tests air purifiers to determine if they meet ozone limits. Mendez explained that ozone can be a by-product of some air purifiers. It's important to note that an air filter cannot remove moisture from your home or prevent the infiltration of outdoor air. Not all filters are created equal, so choosing the right one depends on what you need to purify from the air.
While these filters have a low MERV rating, they are a great long-term investment for someone who doesn't have strong preferences about HVAC filter types and doesn't need any special filters. In addition to its HEPA filter, the Cusinart air purifier also features washable and reusable metal filters and activated carbon filters, all of which work together to capture 99.9 percent of airborne particles of 0.1 micron or greater. These filters aren't known for improving air quality, as they can't put much effort into it and can only trap some of the dust and allergens. When it comes to selecting an air filter, it's important to consider all factors such as cost, efficiency, and maintenance requirements. Electrostatic filters provide the highest level of filtration for small particles, while HEPA filters meet stringent standards set by both European and U. government agencies.
MERV ratings help determine how effective an air filter is at capturing particles, while AHAM tests help ensure that ozone levels remain safe when using an air purifier. In conclusion, choosing the right type of air filter depends on your needs and budget. Electrostatic filters provide the highest level of filtration for small particles while HEPA filters meet stringent standards set by both European and U. government agencies.
