Q: Are these for the outer door to the furnace or are they for the inside lift off compartment doors? A: depends on the furnace, there should be retainers on the door which holds the filter in place. Q: CAN THIS BE CUT TO FIT A DOOR THAT IS 19' X 26'? However, when the furnace's fan turns on, the suction will sometimes pull the bottom of the filter towards the fan, which stands the filter straight up on the right side of the intake duct. Then, when the fan shuts off and the suction disappears, the top of the filter will fall backwards, thereby allowing unfiltered air into the furnace. If your unit has a standard filter slot (typically located near the blower unit) you can select a filter size within 1/8-in – 5/8-in. Smaller than the two longest sides. As mentioned above, you can also choose a longer filter as there is no door or cover that needs to be closed over the filter.

Is the air filter I have too small for my unit? We hear this question from a lot of our customers. Each air conditioning system or HVAC unit has a certain size filter that allows the filter to perform correctly by protecting your heating/ac system. The filters don't need to fit with an 'air tight' seal, but you should be able to easily install and uninstall your filter without a struggle, plus the filter shouldn't be so small that it moves freely within your unit. Your filter should be a bit smaller on each side of the filter housing slot, thus allowing you to slide the filter in with ease. Most AC and HVAC units use standard sized filters, but some do require a custom size air filter.
Some Signals that Your Air Filter is Too Small:
1. The air filter moves around too much inside the filter housing slot.
2. When your unit turns on, you hear noises such as knocking, whistling, or rattling.
3. Once installed, the air filter does not completely cover the vent or duct opening.
4. You notice that the air filter does not seem to get dirty.

Consequences of Using an Air Filter That is Too Small:
1. The filter can be sucked into the ventilation if it is much smaller than it should be.
2. Dust, allergens and pollutants will not be filtered from your indoor air, as the air is bypassing the filter and entering into the ventilation and is returned back.
2. The filter will be unable to protect your AC/HVAC unit and the unfiltered air will collect on internal components of your system, such as the coil and fan, which can lead to expensive repairs.
If you are questioning whether or not your filter is too small, here are a few suggestions on how to check:
Measure the air filter housing slot, but only the usable space where the filter can fit into. Make sure to take into consideration any overlaps or recessed edges that may obstruct installing or uninstalling the filter. For most systems you can use a standard sized filter within 5/8-in smaller than the air filter housing. If you are not able to find a standard sized filter within that parameter, you will need to order a custom sized air filter.

There are also air conditioning/HVAC units that are open-ended, meaning you don't close a door or panel over the air filter housing. In these cases, you have more flexibility in selecting your filter size, as you can choose one that is longer than the size of the opening. This also gives you a pseudo 'handle' that sticks outside the opening that allows you to grab onto for ease of removal when it's time for the filter to be changed.

How to Choose Your Air Filter Size for Each Unit Type:

1. If your unit has wall and ceiling vents that do not have clips or brackets that secure the filter you want to find the closest fit possible (within 1/8-in. smaller than the opening) that prevents movement or noises as mentioned above.
2. If your unit has wall and ceiling vents that has clips or brackets that secure the filter you can select a filter size within a 1/2-in. smaller than the opening.
3. If your unit has a standard filter slot (typically located near the blower unit) you can select a filter size within 1/8-in – 5/8-in. smaller than the two longest sides. As mentioned above, you can also choose a longer filter as there is no door or cover that needs to be closed over the filter.
4. If your unit has a filter cabinet or drawer/large housing compartment you will need to select a specialty Whole House Air Filter (filter depth should be over 4 inches). Look for the part number or model number on the door/panel/housing or the reference number on the air filter to find the actual filter size. Poker strategy open raising charter.
