High Velocity Air Flow Furnace Filter

This product is ideal for high velocity hvac systems and it lasts up to three months.

High velocity air flow furnace filter.

Increase the pressure in the duct system. Add resistance to 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. To summarize a high merv filter can.

The higher the merv number the more expensive they tend to be. 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. 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 means the filter can handle high flow rates.

Furnace manufacturers prefer the traditional spun fiberglass ac filters merv 2. Purifies air by capturing a high percentage of household air particles including those at 0 3 microns. With that face velocity and those dimensions the air flow rate is 1 367 cubic feet per minute cfm. These filter out enough of the large particles to protect the furnace while providing maximum airflow.

See my article on the continuity equation for more on this. Freeze the air conditioner coil. They used 492 feet per minute fpm as the face velocity because that s what the ashrae filter standard 52 2 calls for. Maintaining the furnace manufacturer s specified airflow is critical to achieving energy efficiency and maximum life from the blower motor and heat exchanger.

Increase the energy use of the system. Reduce the air flow. This highly rated filter has the highest fpr possible and comes in a wide range of sizes fitting most all furnaces. Filberbuy has several different types of well made furnace filters.

3m filtrete filters are an economical upgrade from cheap one month filters. 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. The 3m filtrete dust pollen furnace filter is an electrostatically charged furnace filter ideal for high velocity hvac systems. It has an electrostatically charged design capable of attracting and trapping larger allergens.

Most residential filters range from 4 to 12.
