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.
What MERV rating should I use for Covid 19?
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 MERV rating is recommended for home?
between 8-10
What MERV rating is best for air flow?
Air filters that are MERV 13 and higher are recommended for those that prioritize air quality and may have to handle asthma, severe allergies, and other similar circumstances.
Do MERV 13 filters restrict air flow?
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.
Is a MERV 11 filter too restrictive?
Air filters with higher MERV ratings can filter more, but the thickness of the filter material can restrict airflow. Restricted airflow can decrease comfort, increase energy use, and accelerate the wear and tear of HVAC components. In most cases, a MERV 11 air filter isn't too high for residential use.
Do some air filters restrict airflow?
All filters will restrict the air flow to some extent because, in every case, the air has to move through the filter for the unit to be able to remove the particles in the atmosphere. The higher the MERV rating, the denser the filter is going to be, and so the more restricted air flow will become.Nov 5, 2018
Is MERV 13 too high?
In some cases, using an air filter that is too restrictive for your system may cause low air flow problems as well. MERV 13 is the highest MERV value safe for residential furnaces; the higher ratings are used primarily in commercial units. ASHRAE recommends MERV 6 or higher. US Department of Energy recommends MERV 13.
Does MERV 13 stop Covid?
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. By itself, using an upgraded HVAC filter is not enough to protect people from COVID-19.
Is MERV 14 too high?
MERV 14 is too strong for most home HVAC systems. And these are some of the best on the market. MERV is an industry-standard, or rating. The abbreviation stands for Minimum Effective Reporting Value. In other words, it's a measurement showing how small the holes are in the filter.
What is the advantage of a thicker air filter?
A thicker filter (4-5 inches) has more surface area and therefore allows more room for air to pass through. Thick filters, due to their increased surface area, also have other benefits like: Higher dust-holding ability (meaning it can catch a lot without blocking airflow)
Is a 5 inch filter better than a 1 inch?
Enhance Indoor Air Quality Replacing your standard one-inch air filter with a pleated 5-inch filter can result in better air quality inside your home. That's because bigger air filters feature higher MERV ratings, leading to better filtration of pollutants and allergens.
Is it better to have a thicker furnace filter?
Most air filters are 1 inch thick, but some systems can accommodate filters 2 to 5 inches thick. In our tests, we found that the thicker the filter, the better it works and the longer the replacement intervals. That means it's better for you and for your heating, ventilating, and air conditioning (HVAC) system.
