FAQ

How do filter boxes work?

In-line filter boxes can be mounted at any point in a duct run between ducts. The filter box has a male end spigot on either side which fit into the ducting (female end). Extracted air travels through the duct run and reaches the air filter box HVAC where it passes through a panel type filter. These filters remove contaminants from travelling further through the duct work, preventing them from reaching fans, coils, heating coils, and areas being ventilated. 

How often should I change my HVAC air filters?

All filters need replacing and should be checked regularly. Filter life depends on the amount of particulate being captured. 

If panel type filters are not properly attended to, they can easily become clogged and in turn preventing air flow. This loss of airflow can sometimes cause the system to overheat and could, over-time, lead to equipment breakdown or even fires. Changing the filters in your air duct filter box regularly is crucial for health & safety and a HVAC systems longevity.
