MERV 13 filters are ideal for homes where air quality is a top priority. They're ideal for households with allergies, asthma, and respiratory issues. Using a MERV 13 filter can also help improve indoor air quality in households with immunocompromised family members and homes with pets that require extra protection.
Our MERV 13 filters are suitable for urban homes near traffic and light commercial spaces, such as offices or medical waiting rooms and even clinics in some instances. Shared living spaces and rental units may benefit from MERV 13 filters, as the filter is designed to capture even more particles than alternative ratings.

Check the label on your current filter or use a tape measure to get the exact length, width, and depth before selecting your size.
Nominal size
Nominal size is what you normally see printed on the label. This is usually a rounded size which is often not the true size of your filter.
Actual size
Actual size is the true size of the air filter, usually written in smaller font below the nominal size.
Measure your current air filter or the length, width, and depth of the opening slot to get the actual size. Round it up to the nearest whole inch to get the nominal size.

For best indoor air quality, we recommend you change your filters regularly at different times depending on your situation.
Replace your air filter every 6 weeks to minimize the circulation of bacteria and allergens in the air.
Replace air filters every 2 months to reduce odors as well as pet dander and hair buildup in your system.
Replace your air filter every 2-3 months to reduce airborne particles and maintain cleaner indoor air.
Keeping your air filter replacement schedule in mind can be challenging to say the least. Make your life easier with Filter King's auto delivery.
You should replace most 25x32x2 air filters every 30 to 90 days depending on your specific needs and circumstances. In households with asthma or allergies, replace your air filter every 6 weeks. If you have pets, replace it every 2 months. If you have young children, replace it every 2 to 3 months.
Using the wrong size air filter can lead to poorer air quality and cause problems for your HVAC system. If the air filter size is too small, unfiltered air can bypass the filter and allow for dust to enter your HVAC system.
No, never cut air filters to fit your filter slot if you’ve ordered the wrong size. Cutting damages the filter frame and media, creates gaps for air bypass, and reduces filtration effectiveness. If you've ordered the wrong size, Filter King offers a 30-day money back guarantee, so you can easily return or exchange your filter for the correct size.
In many cases it may be worth the extra cost, although it largely depends on your specific needs and circumstances. Higher-quality 25x32x2 filters often provide better filtration, last longer, and protect your HVAC system more effectively, meaning that the investment pays off through better air quality and reduced system maintenance costs.
No, never run your HVAC system without a filter, even temporarily. Running it without a filter allows dust, debris, and particles to enter your system, which can lead to expensive damage to components like the blower motor and evaporator coils.
A MERV 13 25x32x2 filter may restrict airflow in some of the older or lower-capacity HVAC systems, while most modern residential systems should handle a MERV filter without issues. If you notice reduced airflow, longer heating/cooling cycles, or increased energy bills after installing a MERV 13 filter, consider changing to a MERV 11 instead.
