Image
A central fan-integrated supply system uses a fresh air intake ducted to the home's central furnace or air handler unit to supply fresh air throughout the home
Image
All return air and mechanically supplied outdoor air pass through filter prior to conditioning
Image
Filter access panel includes gasket or comparable sealing mechanism and fits snugly against the exposed edge of filter when closed to prevent bypass
Image
Filter located and installed so as to facilitate access and regular service by the owner
Image
Furnace filter resistance varies by surface area; deeper pleats add surface area
Image
Furnace filters that are MERV 6 or higher protect the HVAC equipment and improve indoor air quality
Image
If filter is inaccessible, locate the air filter between the return air plenum and the air handler box
Image
If furnace is accessible, locate the air filter between the return air plenum and the air handler box
Image
If the furnace is hard to access, locate filters at return registers covered by hinged grilles that are easy to open from inside the home
Image
Install a filter with a MERV rating of 6 or higher in each ducted mechanical system
Image
Image
Install the filter media box between the return air plenum and the air handler box
Image
Leaks at the air filter cover panel can draw in unconditioned or undesirable air
Image
Locate the fresh air intake away from pollution sources and in an easily accessible location
Image
Image
Replace HVAC air filters regularly to protect the equipment and maintain system efficiency
Image
Right - Ducts and heat pump cabinet are properly sealed with mastic, high MERV filter is installed, and duct and refrigerant lines are air sealed at ceiling.
Image
Right – HVAC furnace filter is properly installed in cabinet with gasketed cover to prevent air leakage
Image
Image
The air handler of the air-to-water heat pump is equipped with a very high efficiency air filter and a damper-controlled fresh air intake.
Image
The airflow direction is labeled on the edge of the filter to ensure it is properly oriented when installed.
Image
The blower wheel (fan) on this ductless wall-mounted indoor unit has accumulated dust and mold - a common issue for this design.
Image
The edge of this 1-inch HVAC filter indicates it's dimensions, allowing proper matching of filter to air handler
Image
Image
Image
Image
The MERV rating, particle capture efficiencies, and pressure drops are printed on the side of this 1-inch pleated filter
Image
Image
Image
Image
This ductless wall-hung indoor unit has supplemental air filters (outlined in red), which only filter a portion of the airflow; most of the air bypasses the supplementary filters and only passes through the standard mesh filters.
Image
To increase surface area and reduce pressure drop for high MERV filters, the return duct can be constructed to permit the installation of two furnace filters side by side
Image
Image
Wrong - Air filter was compressed and may not function effectively to filter return air.
