If you have a forced-air furnace, it uses a filter. The thinner filters need to be changed every month or so. The thicker filters last longer because of their increased density. What size of filter you can use in your furnace depends on the size of the slot. You may be tempted to use a filter that's not as thick as the slot. That may not be a. The US Stove Universal Filter Box covers the blowers on your USSC furnace and allows for easy connection to the existing HVAC return duct work or to newly installed ducting. This universal filter box is constructed from galvanized steel for durability and includes an integrated slot for a 16 in. My house inspector says I need a 'slot cover' on the furnace filter in the return duct. Where can I buy one? I've tried looking everywhere, but I can't even find evidence that 'slot covers' exist. I'm currently covering the hole in the duct with duct tape.

Three Things To Try If Your Furnace's Air Filter Is Stuck In Its Slot

Many air duct sections leading into furnaces have slots on them that allow you to quickly change an air filter by opening a slot's cover and pulling the filter out by its edge. While this is convenient, it can be difficult to deal with an air filter in this situation that's stuck to a floor or wall without tearing the filter into little pieces. So if your old air filter won't budge at all from its slot in your furnace's connecting air duct, make sure to try these three things.

Run The Furnace To Heat The Filter Area Up

If you haven't had to run your furnace for a long time and you're just changing out the filter now to save on energy and maintenance costs in the coming months, your old filter has had plenty of time to get stuck to the metal around it. This process has been helped along because the temperature around the filter has been mostly constant and without any heat spikes that come from you turning on the furnace.

Giving your furnace a short test run for the season before you change out your filter will give the filter's cardboard border time to expand a little and shake off any chemical or physical bonds holding it down on its own. Even if the initial air stream itself won't be heated until it actually goes through the furnace, it'll get warmer and warmer as it cycles through your home and back into the air duct section holding the filter.

Gently Rock The Visible Cardboard Line From Side To Side

To avoid a huge tear when you finally dislodge a stuck air filter from your air duct's wall, it's a good idea to rock the visible cardboard line from side to side before you pull on it with all your might. First, put one hand on the cardboard near the top and the other hand on the cardboard near the bottom. Then, move your topmost hand left while you move your other hand right. Switch out the directions a few times until you can feel the air filter getting noticeably looser.

Pull On The Top Of The Filter A Little Harder Than The Bottom

Since moisture and gunk tends to collect on the bottom of an air duct more often than it does on the top, the top of a stuck air filter is often significantly easier to pull on than its bottom. Therefore, when you're pulling on the filter in earnest, focus most of your effort on the top of the cardboard. Only make a change if the top feels incredibly loose while the bottom is still as stuck as ever. Of course, if you cannot remove the air filter at all, then contact a furnace repair specialist.

FilterLock® is a patented two-piece system designed for use with 1-inch air filters that eliminates air leakage at the filter slot/door to improve indoor air quality (IAQ) and reduce energy consumption. Energy Star lists air leakage at the filter slot as one of four major issues with duct work in the home.

If not properly sealed, harmful airborne contaminants can enter the heating, ventilating and air conditioning (HVAC) system through the filter slot/door and bypass the air filter. FilterLock® installs in seconds with no tools to eliminate unfiltered air from entering the system through the filter slot/door. Since dirty air that leaks into the HVAC has to be conditioned, FilterLock® can also reduce energy consumption. Built-in magnet fasteners hold FilterLock® securely in place, and it is re-usable indefinitely.
