MERV 13 Air Filters
The COVID-19 pandemic increased the need for buildings to protect occupants from infection due to airborne pathogens. To help protect against COVID-19, ASHRAE (American Society of Heating, Refrigerating and Air-Conditioning Engineers) changed its recommendation from MERV 8 filters to a MERV 13 filter and above. R.P. Fedder sells a full range of MERV 13+ filters and can help you determine what filter types and efficiency ratings you need.
What are MERV ratings?
Understanding MERV ratings is important when selecting an air filter. MERV stands for Minimum Efficiency Reporting Value and is a rating system developed by ASHRAE. All filters have a MERV rating that falls between 1 and 20. The rating describes a filter’s effectiveness at removing particles from the air. The higher the MERV rating, the more a filter can capture and the cleaner the air will be. Filters with high MERV ratings are recommended wherever super-clean air is desired or required.
MERV 13 filters are able to remove particles as small as 0.30 microns from the air, making them an excellent choice for protecting against airborne pathogens like COVID-19.
MERV Ratings Aren’t Standard
It’s important to know that MERV ratings are not standard. They will vary from one brand to the next. One filter with a MERV rating of 14 may be able to remove volatile organic compounds such as formaldehyde from the air, while another MERV 14 filter may not. Reasons include:
- Filter frames and gaskets inside HVAC systems can negatively impact filter efficiency
- Synthetic, charged coarse-fiber filters drop in MERV rating as they’re used
- Some manufacturers claim MERV ratings that their filters simply don’t have
The only way to know for sure is to check the product specifications. To counter this, we carry and recommend the complete line of Camfil premium filters for facilities looking to upgrade their filter efficiency.
Types of MERV 13+ Filters
Our MERV 13+ filters are available in a variety of different types, including pleated air filters, panel filters, and cartridge filters:
- Pleated air filters are the most common type of MERV 13 filter and are available in a wide range of sizes to fit any HVAC system. Pleated filters have a large surface area that allows them to capture more particles than other types of filters.
- Panel filters are another type of MERV 13 filter that can be used in HVAC systems. Panel filters are less common than pleated filters but offer some advantages, including being easier to install and having a longer lifespan.
- Cartridge filters are another option for MERV 13+ filtration and are available in a variety of sizes, efficiencies, and styles.

MERV 13 Filter FAQ
MERV 13 filters should be changed every three to six months, depending on the brand of filter, level of contaminants in the air, and the amount of use your HVAC system gets.
Not changing your air filters can lead to a number of problems, including:
- Dirty air: Air filters capture contaminants from the air, so if they’re not changed, those contaminants will build up and be recirculated through your HVAC system. This can lead to poor indoor air quality and respiratory problems for occupants.
- Increased energy costs: Dirty air filters can restrict airflow and increase the amount of energy your HVAC system uses. This can lead to higher energy bills.
- Reduced HVAC system efficiency: Dirty air filters can reduce the efficiency of your HVAC system, leading to higher energy bills and a shorter lifespan for your system.
- Increased repair and maintenance costs: Dirty air filters can cause damage to your HVAC system, leading to increased repair and maintenance costs.
MERV 13 air filters come in a variety of sizes to fit most commercial and industrial HVAC systems. The most common MERV 13 filter sizes are:
A high-capacity filter is a MERV 13 filter that can capture a higher percentage of airborne contaminants than a standard MERV 13 filter. High-capacity filters are often used in commercial and industrial settings where there is a need to capture large amounts of airborne contaminants.
Some examples of high-capacity MERV 13 filters are:
HEPA filters typically have a MERV rating of 17-20 and are often used in hospitals and other settings where there is a need to capture small airborne contaminants.
MERV 13 filters are less expensive than HEPA filters and they don’t need to be replaced as often. MERV 13 filters also don’t restrict airflow as much as HEPA filters, so they can be used in a wider variety of HVAC systems.
MERV 13+ filters have a pressure drop of 0.45-0.55 inches of water column (wc). This means that it takes more energy to move air through a MERV 13+ filter than it does a MERV 12 filter. The increased pressure drop is due to the larger surface area of the MERV 13+ filter.
There are a few methods you can use to mitigate the pressure drop of MERV 13+ filters:
- Choose premium brand MERV 13+ filters, such as Camfil
- Install MERV 13+ filters in the supply side of your HVAC system: This will reduce the amount of energy your system uses and help keep the return side of your system clean.
- Increase the size of your HVAC system: A larger system will have more capacity to move air through the MERV 13+ filters.
- Reduce the number of MERV 13+ filters you use: This will reduce the pressure drop of your system, but it will also reduce the amount of airborne contaminants that are captured.
The MERV rating you need will depend on the type of business you have and the level of airborne contaminants you need to capture.
If you have a business that generates a lot of dust, such as a woodworking shop, you’ll need a MERV 13 filter to capture the dust particles.
If you have a business that generates a lot of airborne contaminants, such as a hospital or laboratory, you’ll need a MERV 17-20 filter or HEPA filter to capture the small particles.
If you’re not sure what MERV rating you need, you can contact R.P. Fedder to help you determine the right MERV rating for your business.
Yes, you should have a service and repair plan that outlines when and how you will maintain the HVAC system in your facility. This plan should include a schedule for regular maintenance in addition to which tasks will be completed. You should also include a set of steps to follow when an issue arises during maintenance or otherwise.
Some of the advantages of a service and repair plan are:
- They keep you and your facility teams organized: Facility managers already have a lot to keep track of. Having a plan in place removes the burden of having to create new procedures on the fly to address emergencies.
- You control interruption of HVAC during repairs: Several types of maintenance require all or part of the HVAC system to be shut off. Controlling when these outages occurs will allow smooth operation of your facility, whether it contains product, people, or both.
- Service and repair plans lower operating costs: By regularly servicing your HVAC system, you will enjoy lower operating costs. A well maintained HVAC system will have improved energy efficiency, lower need for expensive emergency repairs, and an extended life span which lowers its overall cost per year.
