Can Furnaces Run Without Filters?
Operating your furnace without a filter is technically possible, but it’s not something that’s advised. The presence of a filter is not a fail-safe that keeps the furnace from running, so you can leave it out and the furnace will still cycle as it otherwise would for the temperature you have it set on. But it’s important to remember that the filter in your furnace is there for a reason.
What Does a Furnace Filter Do?
Your furnace’s filter takes dust, allergens, and particles out of the air. Depending on the size and type of filter, it could be rated for larger particles or smaller ones. HEPA filters, for example, take more minute particles from the air along with larger ones. These filters reduce allergy problems and provide you with cleaner air in your home. The furnace filter keeps dust and particles from getting into your lungs, and it keeps them from getting into the main part of the furnace where they can build up, do damage, and reduce efficiency. Over time, these particles can also reduce the lifespan of your furnace.
Change Your Furnace’s Filter Regularly
You’ll want to make sure that the furnace filter is being changed and your unit has regular maintenance service in your Downers Grove, IL home, so the air flow through it is strong. The general advice is to check the filter and replace it every 30 days. While that may not always be a necessity, depending on how much the furnace is used, it’s one of the best ways to ensure that the filter stays clean and does it’s job to the best of its ability. Not getting proper air flow through a dirty filter is something that can shorten the life of your furnace, but you should never just leave the filter out to make sure the air is flowing.
