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.

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.

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.

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