Understand the Basics of HEPA Filtration
November 20, 2022Back to All Articles
Today, it seems like high-efficiency particulate air (HEPA) filters can be found everywhere. You may see vacuum cleaners that say they use HEPA-type filters to weed out allergens. When it comes to catching pollution particulates, it’s hard to beat a HEPA filtration system.
However, the HEPA-type filters in most commercial products are vastly different from true HEPA filters.
The Major Difference
Unlike HEPA-type filters in commercial goods, true HEPA filters are quite large and are intended for use in larger machines. HEPA filters are used in ventilation systems, heating systems and air conditioners in both residential buildings and commercial buildings. Air conditioning systems use HEPA filtration to trap microscopic particles from pollution, allergens or even mould spores. This is the layer of protection that prevents pollution and outdoor debris from entering your home.
HEPA Filter Effectiveness HEPA filters trap particles very efficiently due to their design. If you were to remove a filter yourself, you would see multiple layers of interlocking fibers sandwiched between thin sheets of aluminum. When HEPA filters are properly installed by qualified HVAC technicians, it forms an effective barrier. Large debris is knocked away while tiny particles collide with the internal fibers, embedding themselves in the filter. This is vastly different from the HEPA-type filters in smaller appliances which may have much less accuracy in trapping particulates.
In order to keep your home clean and free of unwanted pollution, it is imperative to schedule regular HVAC maintenance. Over time, HEPA filtration systems become clogged with too many particles. Once this occurs, they must be replaced by an HVAC professional so you can continue to breathe clean air.
If you can’t remember the last time your heating, cooling or ventilation systems have been serviced, contact a reputable HVAC technician today. They can answer any questions you might have about HEPA filters or replace them if necessary.
