High Velocity Air Flow Furnace Filter

This highly rated filter has the highest fpr possible and comes in a wide range of sizes fitting most all furnaces.

High velocity air flow furnace filter. With that face velocity and those dimensions the air flow rate is 1 367 cubic feet per minute cfm. Furnace manufacturers prefer the traditional spun fiberglass ac filters merv 2. See my article on the continuity equation for more on this. The 3m filtrete dust pollen furnace filter is an electrostatically charged furnace filter ideal for high velocity hvac systems.

Flow rate equals area times velocity. Reduce the air flow. Furnace filters are rated by their minimum efficiency reporting value or merv the higher the rating the more efficient the filter is at trapping airborne particles. This product is ideal for high velocity hvac systems and it lasts up to three months.

A minimum merv 0f 4 is needed to protect the furnace a good value to help indoor air quality is 8 9 this blocks more with the max 16. The higher the merv number the more expensive they tend to be. 3m filtrete filters are an economical upgrade from cheap one month filters. Maintaining the furnace manufacturer s specified airflow is critical to achieving energy efficiency and maximum life from the blower motor and heat exchanger.

High velocity means the filter can handle high flow rates. To summarize a high merv filter can. They used 492 feet per minute fpm as the face velocity because that s what the ashrae filter standard 52 2 calls for. Freeze the air conditioner coil.

Increase the pressure in the duct system. Most residential filters range from 4 to 12. The numerical range is from. 4 and 5 filters help maintain airflow in heating and cooling systems which helps prevent stress on the system and reduces the amount of energy needed to reach desired indoor air temperatures.

Purifies air by capturing a high percentage of household air particles including those at 0 3 microns. These filter out enough of the large particles to protect the furnace while providing maximum airflow. Increase the energy use of the system. Filberbuy has several different types of well made furnace filters.

Add resistance to the air flow.
