What kind of filter is best for HVAC?
HEPA-Type Air Filters You can boost indoor air quality with a true HEPA air purifier. These filters are priced higher but are worth it to prevent allergies and bacterial viruses. HEPA type air filters do not trap 99.97% of airborne particles, but they come close. Only true ones meet the exact standard.
Which filter is better HEPA or MERV?
High Efficiency Particulate Air or HEPA have an even higher performance than MERV 16. 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.
Do better HVAC filters make a difference?
Yes, in general, the more expensive air filters are more effective, but a single person with no pets and allergies might not need as much filtration as a family of five with three pets and a child with asthma. Also consider how long your air filter will last.
Are pleated filters better than fiberglass?
While fiberglass air filters will do the job in the most basic way, in most cases, pleated air filters are much better. They can filter out smaller particles – important for people with airborne sensitivities. They are less likely to clog in a short amount of time, and they can last up to 90 days.
Will MERV 13 damage my HVAC?
MERV 13 air filters are the highest-rated air filters for home use. Any air filter with a rating higher than 13 will restrict air flow to the point of which could cause damage to your HVAC system, resulting in an added expense to fix it.
Do pleated air filters restrict airflow?
Even though pleated fiberglass filters are very common and are continuously highly recommended, there’s still a misconception around the filters being able to cause damage to your unit because they supposedly restrict air flow. Yes, pleated air filters do indeed restrict the airflow to your HVAC system.
Are MERV 13 filters bad for HVAC?
What Are MERV 13 Air Filters? MERV 13 air filters are the highest-rated air filters for home use. Any air filter with a rating higher than 13 will restrict air flow to the point of which could cause damage to your HVAC system, resulting in an added expense to fix it.
Does MERV 11 restrict airflow?
But is MERV 11 too high for your needs? Using an air filter with a MERV rating that’s too high is just as bad as using one that’s too low. Air filters with higher MERV ratings can filter more, but the thickness of the filter material can restrict airflow.
What material filters air the best?
Spun fiberglass is an affordable and reliable resource for filtering air and trapping contaminants. Fiberglass is excellent for trapping large contaminants, such as dust and pet dander, and it often helps maintain superior air flow. Many HEPA filters are made primarily from fiberglass.
