This filter is a high quality, economical aftermarket replacement.
Made of 100% synthetic media. It will not absorb water, preventing the growth of mould, fungi and bacteria. Made with fire retardant materials. A rigid constructed housing with efficiently spaced pleats, enabling excellent surface capacity for better filtration of airborne particles.
Spacing of the pleats allows for air travel across the entire surface of the filter and increased filtering capacity. Larger dust particles are captured at the top and bottom of the pleat. Smaller particles will be caught in the sides of the pleat surface.
The filter is constructed from a rigid, fire retardant material. It performs extremely well even in difficult operating conditions. The filtering media is glued to the frame itself, ensuring that the air will not be able to escape, or bypass the filter.
Each pleat is adhesed to the housing frame, protecting the pleat from being damaged or distorted and reducing their efficiency.Higher rated filters allow less air to flow through though and can force your furnace to work harder and possibly malfunction. A MERV rating between eight and 11 is adequate for most homes. To be safe, you should check if your furnace manufacturer has a maximum MERV rating your model of furnace can use.
