Why is my furnace filter so dirty?

The filter clogs up faster when the oven works more frequently. This is because more air is circulated through the filter when the oven goes through more heating cycles, so more contaminants are trapped in the filter media. The colder it is outside, the faster the filter will clog with dirt. Leaving the filter too dirty can cause a short oven cycle or cause the air conditioner to freeze.

Air duct leaks introduce dust and dirt from areas such as the attic. The more dirt a leaking duct system brings to your home, the more dirt the air filter will accumulate. If your oven filter becomes dirty after a week, it's because there is a lot of dirt in the air in your home.

Furnace types with air filters include all central furnaces, ductless mini-split heat pumps, and some plug-in electric heaters. Second, the filter may not get dirty because the oven is not working properly. It's generally wise to rely on the airflow labels on these pre-installed filters, as HVAC professionals have a lot of experience understanding how ovens work.

If you have some furry friends in your house, this could definitely be a cause for oven filters to die quickly. On the other hand, if your oven filter is suspiciously clean for a long time, some things may not be right.
