If you see the filter for your furnace is dirty but you don’t have another one on hand, you may wonder if you can run your furnace without it. While you technically can do so, it’s a bad idea for several reasons. You can run your furnace temporarily without a filter for a day or so, but it’s important to install one as soon as possible.

What Does the Filter Do?

The primary purpose of a filter is to keep your furnace clean. It prevents dust, dirt, pet hairs, pollen and other debris from reaching the important parts of your furnace. When debris builds up in the furnace over time, it causes multiple problems.

The secondary purpose of the filter is to improve the air quality inside your home. A clean filter catches allergens, pollen and other debris that can cause health problems.

Poor Airflow

If you run your furnace without a filter, it results in poor airflow. Critical parts will have increased wear-and-tear, which reduces efficiency and the lifespan of your furnace. You will also experience increased monthly energy bills.

Overheated Furnace

Your furnace can overheat when the filter isn’t present. Debris will collect on components, which means warm air won’t be able to leave it as quickly as it’s supposed to. You may have an expensive repair bill if your overheated furnace sustains damage.

Clogged Ductwork

The filter keeps debris from clogging up your home’s ductwork. When you run the furnace without its filter, your ductwork may collect enough debris to become clogged. You’ll need to have your air ducts cleaned more frequently.

Poor Heating

As a lack of a filter prevents proper airflow, your home won’t be as comfortable. Your home will have rooms that are too hot while other ones are too cold.
