What MERV Can my AC 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 13 too high for 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.
Is MERV 12 too high for HVAC?
When in doubt, choose a MERV 8 to MERV 10 filter rated for high airflow, so it won’t damage your furnace or air handler. Or you can ask a certified HVAC technician what filter is best for your furnace or air handler.
Do higher MERV filters restrict airflow?
Wrong. 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.
What is MERV rating for Covid?
What kind of filter should I use in my home HVAC system to help protect my family from COVID-19? Minimum Efficiency Reporting Values, or MERV, reports a filter’s ability to capture particles. Filters with MERV-13 or higher ratings can trap smaller particles, including viruses.
What is a good MPR rating?
A good MPR rating to start at is MPR 600. Filters with an MPR 600 rating strike a good balance between filtration efficiency and airflow. If you are susceptible to allergens such as fine dust or pollen, moving up to an MPR 1000 filter is the next step in air filtration efficiency.
What MERV rating does Trane recommend?
8 to 13
Most homes are best served by a filter with a MERV rating of 8 to 13, but refer to your system’s user manual or with a Trane® Comfort Specialist for guidance.
How often should you change a MERV 13 filter?
For Merv 8, 11 and 13 filters, we recommend that you change your filter at least every 3 months, however changing your filter every 2 months provides better filtration which provides healthier and cleaner air in your home.
Are MERV 13 filters bad for furnace?
MERV 13 is the highest MERV value safe for residential furnaces; the higher ratings are used primarily in commercial units. If you are wondering what MERV to try, keep these recommendations in mind; ASHRAE recommends MERV 6 or higher.
Is MERV 11 too much?
In most cases, a MERV 11 air filter isn’t too high for residential use. Generally speaking, anything under a MERV 13 air filter should provide very efficient air purification in a home without impacting airflow.
Are MERV 14 filters bad for HVAC?
MERV 14 is too strong for most home HVAC systems.
An excellent home filter is the MERV 13 Titanium. And these are some of the best on the market.
Why are the highest rated MERV filters not used in residential applications?
Why are the highest rated MERV filters not used in residential applications? Most residential air conditioning equipment can not operate correctly at pressure drops exceeding .
What is the difference between MPR and MERV?
While MERV ratings reflect a filter’s ability to trap both microscopic and macroscopic particles, MPR ratings only grade a filter on its capacity to remove particles from 0.3 to 1 microns. For reference, a typical dust particle is between .
What MERV 13 filter?
A MERV 13 filter is a step in the right direction and captures more particles than a typical MERV 8 filter. However, it is not as good at capturing small virus sized particles like a HEPA can. A MERV 13 will trap less than 75% of air particles that are 0.3-1.0 micron in size (the coronavirus is 0.1 microns).
Is MERV 11 or 13 better?
MERV 11 furnace filters have a particle arrestance of a little over 90%. In comparison, MERV 13 HVAC filters have a particle arrestance of around 98%. Naturally, it is significantly more efficient. MERV 11 rated air filters are ideal for those who live in a moderately polluted area, have mild allergies, or own a pet.
What is the MPR rating on filters?
*Your filter’s MPR (Microparticle Performance Rating) indicates its ability to capture tiny particles between 0.3 and 1 micron in size. The higher the MPR, the more microparticles—such as pollen, pet dander, smoke, bacteria and viruses—your filter will capture from the air passing through it.
Does MERV 13 filter mold spores?
While a MERV 13 filter can catch dust, pollen, mold, and bacteria, it can also filter out smoke, smog, and even virus carriers. In fact, there aren’t many airborne particles that a MERV 13 air filter can’t catch.
What MERV rating does Goodman recommend?
With Minimum Efficiency Reporting Value (MERV) ratings of 11 or better, Goodman furnace filters are built to keep the air quality of your home at optimum levels. Goodman filters will trap air particles like pet dander, dust, dust mite debris, smoke, auto emissions, pollen and mold spores.
What MERV rating does Rheem recommend?
MERV 8
What MERV rating does Rheem recommend? Rheem recommends filters of MERV 8 and above. This MERV level is strong enough to remove substances like pollen, dust mites, dust and pet dander from the air.
What MERV rating is best for Carrier furnace?
12 – 16 MERV
Selecting a good quality filter with 12 – 16 MERV to remove a high percentage of offending particulates. Be sure to check your filter at a minimum of once per month.
