What are HVAC Air Filters?

HVAC filters are used in warming, ventilating, and air conditioning units. They remove the dirt, pollen, and other fine particles from the air so that you and your family can breathe safely. These nanoparticles are caught in the filter and are not recirculated throughout your house, making your environment safe to breathe.

Filters are also used to keep bigger particles out of your system. Several HVAC filters are intended to increase the quality of the indoor air as well as preserve the HVAC system from destruction. Buying it from a residential air filter supplier can save you more money and time.

What Causes Wet HVAC Air Filters?

Wet air filters are caused by a blockage in the air conditioner’s drainage system. Condensate leaks are a common cause of wet air filters. When your HVAC system cools down the air in your house, it also converts the moisture from water vapor to liquid. A condensate leak by a blocked drain or an incorrectly installed HVAC system might overflow and saturate the filtering medium.

Unfortunately, drains can become clogged with dirt, debris, and algae growth. If the water has nowhere to go, it will flow back into the drain pan until the condensate overflows, and the HVAC air filter will get wet. Water is another probable cause of this issue. A working air conditioner produces water as a natural byproduct.

When the system draws warm air from the house for cooling, the moisture in the air condenses into the evaporator coil and drops into the drain pan. Whenever anything prohibits this water from properly draining, it overflows, resulting in a wet HVAC air filter.
