Do Furnace filters have to be exact size?

Can you cut a furnace filter to size?

What happens if your furnace filter is too small?

If the filter is too small, it won’t cover the entire space and may allow dust and dirt to flow past. If you’re not sure what size filter you need, check the manufacturer’s specifications or ask your HVAC technician for help choosing the right product.

Are wider furnace filters better?

Most air filters are 1 inch thick, but some systems can accommodate filters 2 to 5 inches thick. In our tests, we found that the thicker the filter, the better it works and the longer the replacement intervals. That means it’s better for you and for your heating, ventilating, and air conditioning (HVAC) system.

Can I use the wrong size air filter?

1) Letting the air filter work overtime The same could be said with your air filter. When you leave it in your return duct for too long and it gets caked in dirt, it’s no longer working efficiently. Not only that, it’s actually hurting your heating and cooling system and raising your energy bills.

What happens if you use the wrong furnace filter?

Can I use a 2 inch filter instead of 1 inch?

As you can see the 2 inch filter will serve our needs MUCH better than the 1 inch filter. Even if the duct system is in good shape, using this filter will keep the system from struggling.
