Check your filter each month to see if it looks dirty, discolored, or clogged. If less air is coming out of your vents, you might have a clogged filter, so replace it.

You shouldn’t run your furnace without using an air filter. It could damage your HVAC system and cause the need for expensive repairs. The main reason to use an air filter is to trap dust, pollen, pet dander, and other particles. These contaminants circulate through your ductwork if you don’t use a filter, and can gather on your blower motor, heat exchanger, and other parts of your system. Not using a filter can also reduce your furnace efficiency and cause you to have higher utility bills. Your furnace could overheat without a filter and in severe cases, could become a fire hazard. When you don’t use an air filter, your system might still work, but in the long term, it could cause significant damage leading to premature failure. The air quality in your home will be greatly reduced. To avoid these issues, make sure you use a clean filter in the proper size in your HVAC system and regularly replace it when it's dirty.
