Air filters in your HVAC system has two main purposes. Most people are already aware of the fact that air filters can help to reduce any airborne dust and other contaminants floating through the air. Another known function of the air filters is to protect your heating and cooling system itself. When you have an efficient air filter in your unit, it helps to minimize the amount of dust that enters into your home. By minimizing the dust inside of your home, you are effectively doing your part to reduce allergies. Using an activated charcoal filter will help to reduce odors that a traditional filter cannot.
If you have a system that is designed to work with a HEPA filter, it will offer the most amount of benefits for your home. These particular filters were designed to help eliminate even the smallest of particles that a traditional filter will miss. For those who need enhanced filtration for allergens, or if your system isn’t built to handle them, you might want to consider using these filters that are designed for your HVAC system.
Heating and cooling systems are designed for efficient operation by using filters that help to impede the flow of air by a specified amount. Once the filter becomes clogged with pollutants and dust, the filter impedes the flow of air so much that the fan motors will become strained. If the heat pump or air conditioner is not charged properly, it can ice over easily than when the filter becomes clogged and risks causing severe damage to the entire heating and cooling system. When the system isn’t properly charged, it either doesn’t have enough coolant or it has too much.
The cost of operating your system will increase if the filter needs to be cleaned or changed, as well as if the system doesn’t have the proper charge. Many of the modern systems of today will come equipped with sensors that measure airflow reduction caused when the air filter is clogged. The system will alert you when it is time to replace or clean the air filters in the system.
