Can a Heater Work without a Filter?
Allergy season is coming up, prompting many homeowners to remember to change their air filters so they’re not left in the dust (sneezing and coughing because of it). Most technicians and AC/heating manufacturers recommend replacing an air filter in a home once every month or, at most, every 3 months. However, if you don’t suffer from allergies, this may not seem like a priority.
Instead of running out to the store to get a new filter every 3 months, we have heard of people opting to pull out the old filter and wait to replace it. But we’re here to warn you that you should never run a furnace without a filter.
A Common Filter Misconception
Many people assume that a filter is mostly in place to help prevent allergens and other contaminants from recirculating in the air. Of course, this is partly true. Any visit to a hardware store to purchase a new filter will reveal that there are different filter ratings that allow for better levels of filtration for the smallest of contaminants that make people sick.
However, this isn’t the primary reason for the existence of a filter. The most basic filters won’t block many allergens, but they will stop larger pieces of debris from pummeling the system and causing damage, which is why it was put there in the first place.
The Problem with a Dirty Filter
A dirty filter is not so much of a concern for your indoor air quality as it is for the performance of your HVAC system. Suddenly, your heater cannot suck in the necessary amount of air needed to operate thanks to dirt and debris blocking air from flowing in. This can cause the furnace to overheat and the blower motor to become overworked.
The Problem with No Filter
To resolve the problems of a dirty filter mentioned above, you might try removing the filter altogether. But as we have mentioned, the filter is a necessary component. Without the filter in place, debris in the air could hit the metal components of the furnace, making dents that cause it to wear down too soon.
More likely, bits of dust and debris will get lodged in the blower fan. This could jam the motor and lead to its early replacement. At the very least, it will stop your furnace from working properly, and could force it to overheat. This is why you should never run a furnace without a filter.
How to Make This Task Less Tedious
We know that replacing the filter is not a chore many people enjoy doing. You can reduce the amount of trips you have to make to the store by investing in a reusable filter that you clean every few months instead. Keep in mind, though, that these may be more subject to mold growth and obstructions.
You can also reduce the work by calling in technicians for maintenance once a year. You should still change the filter every few months on your own, but annual maintenance takes away one month of work for you and includes a full tune-up that makes your heating equipment run efficiently and safely.
