High Velocity Air Flow Furnace Filter

This furnace filter has an fpr rating of 10 or a merv of 13 meaning it can capture particles as small as 3 microns and it even has an electrostatic charge that helps attract microscopic particles.

High velocity air flow furnace filter.

Furnace manufacturers prefer the traditional spun fiberglass ac filters merv 2. They used 492 feet per minute fpm as the face velocity because that s what the ashrae filter standard 52 2 calls for. 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. That s only a benefit as long as the air flow isn t so low that it turns the condensate to ice.

Increase the energy use of the system. The 3m filtrete dust pollen furnace filter is an electrostatically charged furnace filter ideal for high velocity hvac systems. 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. Reduce the air flow.

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. To summarize a high merv filter can. Most residential filters range from 4 to 12. It has an electrostatically charged design capable of attracting and trapping larger allergens.

Filberbuy has several different types of well made furnace filters. The numerical range is from. Flow rate equals area times velocity. These filter out enough of the large particles to protect the furnace while providing maximum airflow.

With that face velocity and those dimensions the air flow rate is 1 367 cubic feet per minute cfm. Increase the pressure in the duct system. The higher the merv number the more expensive they tend to be. See my article on the continuity equation for more on this.

Purifies air by capturing a high percentage of household air particles including those at 0 3 microns. Add resistance to the air flow. Freeze the air conditioner coil. High velocity means the filter can handle high flow rates.

Maintaining the furnace manufacturer s specified airflow is critical to achieving energy efficiency and maximum life from the blower motor and heat exchanger.
