Can I Run My Furnace Without An Air Filter?

The air filter is one of the most important parts of your furnace, but they also are easy to forget about, especially whenever it comes to changing them. If you are in a situation where you need to replace the air filter but don’t have an extra filter available, you might ask yourself “Can I run my furnace without an air filter?”

Well, you can, but the air filter is important for a reason, so running a furnace without a filter is a short term solution. But why is the air filter so important, and what happens when you run your furnace without one?

What Does A Filter Do?

All furnaces have filters, no matter what. The filter’s job is to catch any dust or debris that makes it into your furnace, and keep all that stuff out of the air. After all, no one wants to have dust or allergens circulating through their home. Especially when you turn on your furnace to get warm, not to deal with air trouble!

But as your filters catch and entrap the dust, they can also get clogged and become less effective over time. So whether your filter is disposable or reusable, you need to clean or change it periodically to make sure that it will continue to provide clean air every time you turn on your filter.

What if You Have a Dirty Filter?

Clogged filters might not just be impacting your health, but they can also impact your wallet. When your furnace is dealing with a clogged filter, then it has to work much harder to warm up your house and push all the warm air through all the dust and the grime. A harder airflow causes the furnace to run both hotter and longer.

Then this causes your heating bill to go up, and your house will not get as warm. This can certainly mess with you in the winter, whenever you want to get as warm as possible! Finally, the overwork on your furnace can also cause damage to the furnace, and the extra wear and tear could lead to you having to buy an entirely new furnace.

If you’ve noticed that your heating bills are going up and you are having trouble with figuring out why take a look at your furnace and see if your filter needs to be cleaned up.

Running a Furnace Without A Filter

If you don’t have a replacement filter when it comes time to replace your furnace’s filter, then you might decide to run your furnace without one. It’s very important to note that this is a temporary solution at best, and should not be the norm or a long term solution.

If you choose to run a furnace without an air filter, then you might see some serious problems. These problems can easily become serious if not fixed.

One of the most common problems is poor air quality. Without a filter in place to catch the dust and debris that gets into the furnace, then all of that gets into your vents and then into the air. This leads to your home having poor air quality, which can cause even more problems for you and your family’s health.

If your family has breathing problems, allergies, or asthma, then their symptoms will become worse. Additionally, the duct work in your home that all the hot air goes through will become dirty and this can cause mold and more problems for your air quality.

Damage To Your Furnace

While we like to think that the filter is only in place to keep the dirt and dust away from the air in our homes, the filter has another purpose. That purpose is to keep the dust and dirt away from the furnace fan itself.

Too much buildup of dirt can damage the fan of the furnace and even jam the furnace motor, and that is two very expensive repairs that you will need to deal with! If you don’t have a filter in place, then the furnace can break down.

When Should I Change My Filter?

Now that we know how important changing the filter is, then when exactly should you change it? Well, most experts say to change the filter every 1-3 months, or if you have a reusable filter, then you should clean it every 1-3 months.

In order to make this easy, most retailers offer a subscription service that will deliver a filter to you every few months once you sign up. That way, when you get a new filter, you will know when to change it.

For a reusable filter, there will typically be instructions that will show you how to clean it included with the filter. Make sure to follow those directions whenever you clean the filter, and never insert a wet filter into the furnace. Always wait for it to dry.

Maintaining Your Furnace

The filter isn’t the only thing that could cause some trouble for your furnace. In addition to making sure that your filter is clean and ready to go, you should also check the vents and radiators that the furnace is attached to.

If they get dirty and coated with dust, then the effect is the same. The hot air has to work harder to get to your room, and then your furnace runs for hotter and longer. So always make sure they are cleaned regularly, and that nothing is blocking the airflow to the vents either.

But working with our team at FilterKings will help you make sure to always remember.
