Question: Can You Use A Different Size Air Filter?

Are air filters washable?

Can I use the wrong size air filter?

When you use the wrong size air filter, or you install it incorrectly, the filter can’t effectively prevent dust from accumulating on the system’s motors and blowers. You’ll end up with a dirty furnace that can’t properly perform, and all of that debris could end up harming the system’s internal components.

What if my air filter is too big?

If you have a filter that is too big for your system, it may seem like an easy enough fix– just fold it over or trim it down, right? … The debris will quickly build up in your AC system, as well as being blown into your home. Heating and cooling systems should always be operated with the proper filter installed.

Can I use a 1 inch filter instead of 4 inch?

While a 4-inch-thick filter is more efficient than a 1-inch filter, the right size depends on your furnace. If you measure the filter slot, and it’s large enough to accommodate the thicker filter, then you can use it. However, if the slot is less than 4 inches wide, you’re stuck with using that thickness.

What happens if you put an air filter in the wrong way?

How tight should an air filter fit?
