Learn how to determine correct size for household air filters and how to ensure they fit perfectly for optimum performance.

How to Ensure Your Air Filter Fits Perfectly

It is not necessary for the filters to have a “hermetic seal”, but they should be easy to install and uninstall, and not too small to move freely within the unit. To get a good fit, you should change the measurements of your existing filter. An oven filter must fit inside the unit. If it is too loose, air will continue to enter even while the oven is running.

On the other hand, if it's too tight, you may not be able to remove the filter when it's time to change it. One of the first steps you should take to ensure that your system is operating at optimum performance is to determine the correct size of the household air filters to be used. There are different types of air filters available, both in size and thickness. According to experts, air filters will work best with a tight fit.

If there are gaps around the filter frame, it may not be the right size for the system. The size is indicated on the side of the filter frame. Ideally, the ventilation filter should fit as closely as possible. If a filter does not fit perfectly, unfiltered air will pass through the path of least resistance, and the filter will be partially, if not completely useless.

Particles that bypass the filter can accumulate on the mechanical parts of furnaces and air conditioning units, and deteriorate proper mechanical working conditions over time. If left unattended, this creates the need for costly repairs, part replacements, or, in extreme cases, total replacement of the unit. No, you should not stack the air filters to fit in a larger slot. Seeing that, I went to Amazon and brought a filter of that specification from the Nordic brand (20x25x).

If your oven filter sticks out of the unit, you don't have the right size filter for your specific oven. Here's a fun fact: 70% of what Filterbuy sells is out of the 10 most common air filter sizes. This means that if your air filter is not properly sized and sealed, all air and pollution will surround you and prevent seepage altogether. This leads to a somewhat loose fit and, because it is a location on the roof, the filter must be kept in place to close the vent. When buying a custom-sized air filter, it's important to remember the difference between nominal and actual measurements.

If you have respiratory problems, asthma, allergies or other respiratory problems, a dirty oven filter could be the culprit. Basically, when you take measurements of an air filter, you just need to round up or down to find the dimensions of the filter you need to buy. For common brands of HVAC systems such as Goodman, Lennox, Trane, Rheem York, Coleman and Carrier, most standard air filters will work. Installing several air cleaners 1 in a slot of 2 can cause costly damage to an air conditioning unit since residential furnaces are not equipped to withstand this level of airflow restriction. Before wasting time with an HVAC unit manipulator or return air central ventilation adjuster first adjust the thermostat to turn off the air conditioning system.

At the same time, a coarser filter is less restrictive and will allow better flow of purified air. Because AIRTEVA air filters feature a patented leakage protection seal, they do not have to be adjusted end-to-end. This ensures that your system is operating at its best performance while also protecting your family from harmful particles in your home's air.
