What Happens If You Have a Dirty Air Filter in Your House?

You may not realize it, but the air filter in your HVAC system plays a major role in your comfort and safety at home. First-time homeowners are often overwhelmed by the idea of HVAC maintenance since a property manager or landlord usually handles repairs and inspections when you’re renting. However, it isn’t as complicated as it may seem, and there are plenty of resources available that can connect you with the professional help you need to address any problem as soon as it arises. If you want to learn more about why changing your filter is so important, read on to find out what happens if you have a dirty air filter in your home.

What happens if you have a dirty air filter in your house?

dirty air filter in house can pose a number of problems for every member of your household. When your filter is dirty, it will spread contaminants throughout your home, including dust, dirt, pollen, and pet dander. This may inhibit your system’s airflow, which will have the practical effect of forcing your HVAC system to work harder and driving up your utility bills. If you have a ducted HVAC system, it will also cause your ductwork to become dirty, which may eventually necessitate a professional cleaning.

Additionally, dirty filters will lower the air quality in your home significantly. The presence of polluted air in your home can cause several health and safety issues like rashes, headaches, eye irritation, sinus troubles, asthma, and allergic reactions. The filter may also cause unpleasant odors, as weaker airflow will prevent your HVAC from being able to dissipate the smell effectively.

Proper care and maintenance is the best way to avoid a dirty filter. You should have a technician inspect your unit annually to ensure that it’s still in good working order. Your filter needs to be changed once every 90 days, but most HVAC professionals suggest changing your filter on a monthly basis if you want your system to provide peak performance. If changing your filter doesn’t alleviate the issues you’re experiencing with your HVAC, call a technician as soon as you can.

How else can you improve your indoor air quality?


There are several lifestyle adjustments you can make that can help improve your air quality, and many of them are easy to make. For example, experts suggest that you should be vacuuming at least once or twice a week, preferably with a vacuum that has a HEPA filter. Items that can trap dust and dirt, like bedding and area rugs, should be laundered as often as possible. Air purifiers can also be useful in high-traffic or frequently used rooms, including your bedroom, living room, and kitchen.

Another thing to keep in mind right now is that the CDC has stressed the importance of proper ventilation at home in recent months because of the global pandemic caused by COVID-19. You should open your doors and windows when you can, and use fans to help move virus particles outdoors if they’re present in the house. Make sure you use the exhaust fans in your bathroom and kitchen, as they also help transport air outside. Even if these fans don’t vent to the outside, they can still prevent a concentration of virus particles in one specific location.

Dirty filters can cause more issues than most homeowners are aware of, but it’s essential that you change yours on a regular basis if you want to maintain a clean indoor environment. You can also make some simple lifestyle changes that can have an impact, like vacuuming more often and making use of air purifiers. Taking these steps is more important now than ever due to the ongoing spread of COVID-19. You should do everything you can to ensure that your home is well ventilated if you want to protect yourself and your family from a wide variety of health and safety risks.
