High Efficiency Filters (HEPA)
High efficiency particulate air (HEPA) filters are usually made of fiberglass and are designed to trap very small particles from the air. The randomly arranged fibers trap particles that would normally be able to pass through the spaces between the fibers, but they are unable to do so because of the chemistry involved. Call Baker & Sons Air Conditioning for replacement HEPA filters in the Sarasota area.
Many particles are trapped as the air flows through the filter because they come within one radius of the fiber and are drawn to it (interception). Other particles are too large to flow through, so they stick to the filter (impaction). Then the smallest particles are trapped as they collide with gas molecules in the filter (diffusion). This delays the speed at which the particle is moving and makes it more likely to be trapped.
In order to be considered a high efficiency filter, a HEPA filter must remove at least 99.97% of any airborne particles that are 0.3 micrometers in diameter or larger. At the same time, the filter cannot reduce airflow more than around 300 Pa (a unit used to measure air pressure).
Importance of High Efficiency Filters
Homes today are extremely airtight. This makes heating and cooling a home more energy efficient, but it also can make the home highly toxic as contaminants build up. For homeowners in Florida and other southern states, cockroach particles can be a concern. These disgusting creatures are nearly impossible to eliminate in warmer climates. Who needs to be breathing the pathogens they spread around?
High efficiency filters step up to make a real difference! Not only does a HEPA filter trap airborne cockroach particles, it filters out many other common home pollutants including dust, dust mites, mold spores, pet dander and smoke, to name just a few of the more common non-microbial air particles.
HEPA filters are also able to prevent the spread of many airborne bacterial and viral organisms. When combined with UVC lights, they provide a back-up system that reduces the risk of diseases spreading.
During the winter when it's time to turn on the heat, installing a high efficiency air cleaner on a the furnace guarantees that your winter indoor air quality is what it needs to be.
There are different filtration systems available. Depending on the design, the high efficiency filter may need to be replaced every month or only once a year.
Air Filter Replacement
The Office of Health, Safety and Security has found that age-related degradation of HEPA filters can invalidate design and safety assumptions based on the use of high efficiency filters. Whether the filter is on an air conditioner or on a furnace, it is recommended that filters be checked at the beginning of each season, then every month thereafter. A clogged filter can reduce the life expectancy of both air conditioners and furnaces by requiring the fan to work harder.
