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 HVAC filters the same as HEPA filters?
An HVAC delivers either warm or cool air throughout your home; consequently, while the HVAC system is working hard to regulate airflow and temperature, its air filter has only a limited reach. Just like an HEPA Air Filter, most high-efficiency air purifiers utilize HEPA style technology, but with more efficiency.
Can you add air purifier to HVAC system?
All homeowners aim to keep the air inside their home clean and healthy, especially in these unprecedented times. 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.
Do AC filters stop 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.
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.
Do you need an air purifier if you have HVAC?
If you have an AC, you don’t need an air purifier:
Air conditioning has got nothing to do with air purification as it is ineffective against dust and pollen. Rooms with AC need air purifiers more than other rooms, as the same air keeps circulating and can only be purified through an air purifier.
Does HVAC UV air purifier work?
Germicidal or UV lights for HVAC systems are used to kill the DNA of germs, viruses, mold spores, bacteria and fungi as they pass through the air handler system. A strategically placed UV light is very effective at killing close to one hundred percent of these harmful pollutants.

What MERV rating can my HVAC handle?
The EPA recommends MERV ratings of 9-12 because it is the most effective at keeping your home’s air clean. A filter with this rating will prevent particulates as small as 1 micron from entering your HVAC system. This rating qualifies as HEPA (high-efficiency particulate absorption) level.
Is MERV 11 bad for HVAC?
A MERV 11 air filter has a higher efficiency rating. … In particular, using an air filter with a MERV rating that’s too high can damage the compressor, heat exchanger, and air conditioner coil. In most cases, a MERV 11 air filter isn’t too high for residential use.
