Reduced Air Quality

Having a dirty air filter in your home means you and your family members are breathing unhealthy air. Poor and unhealthy indoor air quality can have a detrimental effect on your health. If you and other members in your household fall sick more often, or feel more tired and experience more headaches than usual, your air filter could be the root cause behind these health issues. As soon as this happens, you need to inspect the air filter and change it if necessary.

You Have Not Replaced the Air Filter in Some Time

Bad Smells

Due to microbial growth or build-up of bacteria in your home’s air filter, you can experience unpleasant odours that were not there before. When you switch on the HVAC system, the air blows through the dirty filter and the system circulates the bad smell through the ducts and into the living spaces of your home.

Over the course of time, you air filter will become dirty no matter how often you clean it. Running your HVAC system with a dirty air filter for longer periods of time could lead to a series of problems. The dirtier your filter is, the harder your HVAC system has to work in order to maintain the same level of performance. The harder your system will work, the more power it will consume. You can reduce your expensive power bills by replacing your filter at regular intervals.
