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, trapping more contaminants in the filter media. The colder it is outside, the quicker the filter will become clogged with dirt. If left too dirty, this can cause a short oven cycle or even cause the air conditioner to freeze. Air duct leaks can introduce dust and dirt from areas such as the attic.
The more dirt that a leaking duct system brings into your home, the more dirt the air filter will accumulate. If your oven filter becomes dirty after a week, it's likely because there is a lot of dirt in the air in your home. This could be due to having a lot of people and pets in your home, or other sources of dirt. Sometimes, dirt can be blown into your home from outside by the wind. If you turn on your oven and find that the filters are dirty or clogged, it's time to take a closer look at what could be causing this.
Replacing oven filters isn't a difficult job, but it's an avoidable hassle that can end up affecting the efficiency of your unit. Most household heaters that rely on air flow have built-in cleanable filters or are equipped with disposable filters. The tips and data contained in this publication are applicable to ovens with one, two or even more filters. Clean air filters help keep oven systems running efficiently by preventing dirt and grime from accumulating in the system. More air is circulated through the filter when it goes through more heating cycles, which means there is more opportunity for the filter to trap unwanted particles.
This is usually the case when an oven filter has become so dirty that dirt has been absorbed on both sides. Spraying an air freshener on the oven filter is one way to help improve the scent of your home. Furnace types with air filters include all central furnaces, ductless mini-split heat pumps, and some plug-in electric heaters. Additionally, if your oven filter isn't getting dirty, it could be because your oven isn't 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 pets in your house, this could definitely be a cause for your oven filters to get dirty quickly.
On the other hand, if your oven filter is suspiciously clean for a long time, something may not be right. Leaving them untreated can not only kill the oven filter quickly, but it can also lead to higher energy bills. Some ovens even have two or more filters to cover more area or to remove even more dust, dirt and particles from the air.
