However, because of the dense filtration material used in HEPA filters, the air pressure needed to force air through the filter is too great for a furnace or air conditioning fan to handle. A HEPA filter installed in a furnace would restrict the air flow to the point that no air would come out of your vents.
Can I install a HEPA filter on my furnace?
HEPA, high-efficiency particulate filters, are high-grade air filtration solutions that remove up to 99% of the tiniest air particles. … Installing a HEPA filter in your furnace is not recommended as it would considerably restrict the airflow.
Do HEPA filters restrict airflow?
HEPA filters are the gold standard in hospitals and clinics because they remove not only inorganic dust, but microorganisms such as mold spores, bacteria, pollen, dust mites and many viruses. … As filtration efficiency increases, so does restriction to system airflow caused by the filter.
Can HEPA filters be used in HVAC?
A filter of HEPA quality used within heating, ventilation, and air conditioning (HVAC) systems can greatly improve the quality of indoor air by filtering small particles of greatest health concern.
Are HEPA filters harmful?
HEPA filters have caused controversy over concerns that they might shed tiny fibers and be harmful to health. But the latest scientific studies have shown HEPA filters are safe and found no evidence of harm.
Do HEPA filters help with Covid?
When used properly, air cleaners and HVAC filters can help reduce airborne contaminants including viruses in a building or small space. By itself, air cleaning or filtration is not enough to protect people from COVID-19.
What are HEPA furnace filters made of?
High-Efficiency Particulate Air (HEPA) filters use borosilicate glass or polypropylene plastic fibres to filter out dust. These long, scientific words mean that HEPA filters are the heaviest-duty option available, and they will have MERV ratings of 17 through 20.
Why are furnace filters pleated?
A pleated air filter is mode of a wire back synthetic media that traps and absorbs more particles than spun fiberglass. The air filters increased quality cause it to have a higher price range than lower style filters.
Are high MERV filters bad for furnace?
While the highest MERV ratings are the most effective for air quality, they can harm your HVAC system. A higher MERV rating means a higher resistance, which means less airflow. … If the MERV rating on your furnace is too high, it may force your furnace to work too hard and leave it vulnerable to damages.
What MERV rating can my furnace handle?
The ideal MERV filters for both air filtering and furnace efficiency are 7-13, experts say. These filters can be used without any modifications to your equipment. Your system may handle MERV 14-16 with no discernable stress.
What is the difference between a HEPA filter and a MERV filter?
While a MERV 16 filter captures >95% of particles in the entire test range (0.3-10.0 microns), a HEPA filter captures 99.97% of particles with a size of 0.3 microns. … HEPA filters can capture many airborne germs, and also nonliving pollutants like fine particulate matter.
Can you put an air purifier on your furnace?
While a high-performing HVAC system with good air filters can help make this possible, it would be an excellent idea to add an air purifier, as well. Dependable Heating & Air Conditioning, an expert in air conditioning maintenance in the area, explains why. Heating and cooling systems have air filters built into them.
Do HEPA filters have a MERV rating?
HEPA air filters are not MERV rated as they exceed the ASHRAE test protocol 52.2 used in determining the MERV ratings. In fact, HEPA air filters are the ONLY mechanical air filters that are tested and certified to meet a specific efficiency at a specific particle size.
Do HEPA filters contain asbestos?
HEPA filters are known for their ability to filter out some of the most difficult particles, and that includes asbestos. Asbestos particles range from 0.7 to 90 microns, making HEPA filters effective at this task. In fact, in many commercial buildings, HEPA filters are primarily used for this very purpose.
Are HEPA filters made from fiberglass?
HEPA filters use hundreds of thousands of fiberglass fibers—incredibly small and sticky for particles that try to pass through them. This tight weave of fibers then captures particles larger than 0.3 microns in size.
What is the difference between a HEPA filter and a regular filter?
A: The main difference between a HEPA filter is that it is made of thin fibers of glass and activated carbon-based materials. Regular filters are made of porous materials like cotton paper sheets and polyester. Q: How does a HEPA filter work? A: HEPA filters work by forcing air through a fine mesh.
