Can I Use a Slightly Smaller Air Filter? - The Expert Guide

Using an air filter that is not the correct size for your air conditioning system can have a negative impact on its efficiency. The filter has air resistance and a gap does not, so if you leave a 1-inch gap, a disproportionate amount of air will flow through the hole, making the situation even worse. There are many options to buy air filters conveniently, either online, through your air conditioning company, or in-store. A higher MERV rating indicates that the filter has a finer mesh and is capable of removing smaller particles from the air.

Replacing the air filter regularly is an essential task if you want your air conditioning system to work efficiently. For common brands of air conditioning systems, such as Goodman, Lennox, Trane, Rheem York, Coleman and Carrier, most standard air filter sizes will work. Installing a smaller filter will allow unwanted contaminants to pass through and enter your home's air and air conditioning system. If you have to clog the air filter to install it, try a third-party oven filter or a custom-sized air filter with a slightly smaller actual size.

To make sure that the next filter you buy is the correct size for your system, you must measure the interior dimensions of the air filter inlet. There are several great options for buying air filters online and getting them delivered to your doorstep. If the filter is too small, it will come loose and some of the air (and debris) will not pass through the air filter. If an air filter is too small, air gaps will be created and contaminants will not come into contact with the filter material.

On the other hand, if the filter is too large, the frame will wrinkle, air flow will be restricted, and longevity will be compromised. Don't stack several small air filters on top of each other to fit in a larger air handler. Most people won't be able to find the size of air filter they need at the local home improvement store. It's important to remember that using an incorrectly sized air filter can reduce the efficiency of your heating and cooling system.

If you're unsure about what size you need for your system, it's best to consult an expert or measure your current filter before purchasing a new one. Buying an appropriately sized filter is essential for ensuring that your home's air remains clean and free from contaminants. It's important to take into account all factors when selecting an air filter for your system: size, MERV rating, type of material used in construction, and cost. The right size of an air filter can help improve indoor air quality by trapping dust particles and other allergens that can cause health problems.

Additionally, it can help reduce energy costs by allowing more efficient airflow through your HVAC system.
