Some manufacturers can even customize filters to fit perfectly when you or your HVAC team put it all together. In a nutshell, yes, you can cut off an air filter if you know what you're doing, and if the filters you use aren't weakened too much from the cut. Cut-to-fit air filters offer the same benefits as regular air filters, with just one addition. Not only do they keep the air in your home clean, but you can also cut them into any size or shape you need.
Bending or cutting the filter also decreases its structural integrity. The entire filter can collapse while installed, creating not only a performance problem and a potentially costly repair, but it can also create unsafe conditions. Should I cut the HVAC air filters to fit the space? The purpose of the HVAC air filter is to keep the system clean. Some manufacturers can even customize filters to fit perfectly when you or your HVAC team put them all together.
In short, yes, you can cut an air filter if you know what you're doing and if the filters you're using aren't weakened too much from the cut. Cut-to-size air filters offer the same benefits as regular air filters, with an addition. Not only do they keep the air in your home clean, but you can also cut it into any size or shape you need. You also need to make a slightly larger filter if you are going to use air cleaner installation tape to secure the filter.
Cutting charcoal to fit air filters into return vents might be all you need to get rid of the stagnant odors that plague your home. Even if the shape is correct, it will be difficult to find an air filter that fits securely in these vents. The air cleaner installation tape runs around the perimeter of the vent where you want to install the filter. If you have a custom-shaped vent, you don't need to buy a custom-shaped filter just to keep the air in your home clean.
Next, I'll discuss how cut-to-size air filters will benefit your home, when you should use them, and how easy it is to install them. Using a carbon cut to adjust the air filter is the same process as any other cut to adjust the air filter, except that it also eliminates odors. In addition to eliminating odors, this material also traps large particles, which extends the life of your HEPA filter. While it is true that while air filtered by high-efficiency filters is cleaned of harmful particles in the air, the HVAC system does not handle enough air volume per hour to keep the air in the house clean.
If you rent or live in a location where you can't install a normal return vent, then a cut-to-size air filter is your only option. The worst thing that can happen is that if you cut the filter too small, particles that would normally be trapped by the filter will be avoided. After obtaining the length and width of the AC filter slot, cut a piece of filter media and place it in the groove. My favorite use case for cutting charcoal for air filters is in a window air conditioner that is in a work area, such as a garage or workshop.
But what happens if that filter breaks or is lost? You definitely don't want to run your window air conditioner without an air filter. The air cleaner installation tape runs around the perimeter of the vent where you want to install the filter.
