Homeowners are becoming more aware of the air quality inside their homes. One of the most effective tools you can use for cleaner air is a HEPA filter. This article goes over the benefits of HEPA filters in the home.
What do HEPA Filters Do?
HEPA is an acronym that stands for “high-efficiency particulate air”. A HEPA filter is able to capture smaller particles than a regular air filter. In order to be labeled as HEPA, the filter must trap 99.7% of particles that are .3 microns or larger. If a filter is labeled “HEPA-like”, it is not a true HEPA filter.
Applications for HEPA Filters in the Home
HEPA filters were originally designed for nuclear facilities before being used in hospitals. Today, there are multiple applications for them in the home to make your indoor air as pure as possible. Here are three ways that HEPA filters are used in the home.
A home air purifier pulls in air and filters out particles like dust, pollen, and dander before sending the air back into the room. Portable air purifiers are rated by the size of the room they can handle and a clean-air delivery rate, which measures the speed of purification.
A HEPA air purifier will remove more contaminants than a non-HEPA model because it has a finer mesh with more layers for the air to travel through. In general, HEPA filters need to be changed more frequently than regular ones. They become clogged more quickly because they collect pollutants at a higher rate.
If you have pets or suffer from allergies, investing in a HEPA-filter vacuum is a must. A vacuum with a HEPA filter will remove many more contaminants from the surfaces in your home. Dust, pollen, and dander in carpets and on furniture in your home are sent into the air when disturbed, so using a HEPA-filter vacuum will improve your air quality.
The filter in an HVAC system plays an important role in cleaning the air that circulates through the ducts. There are many different types of HVAC filters to choose from, including HEPA filters. If you use HEPA filters for the HVAC system, change them more often than the manufacturer’s recommendations.
