Plastic AC filter case with filter to exchange

Description

BACKGROUND ART

There is a known AC filter pad used without frames and some have this ac filter that is made of cardboards which are disposable. But the common problems with the disposable pleated or cardboard air filters are leading to ac units' malfunctions. The Ac filter Pads are common air handlers used in ac systems without frames.

DISCLOSURE OF INVENTION

A plastic ac filter case is a new way of protecting AC units from failing.
This invention's advantage is durability, and the convenience to save from always buying disposable ac filters, instead exchange filter pads.

TECHNICAL FIELD

The present invention PLASTIC AC FILTER CASE WITH FILTER TO EXCHANGE generally relates to improving ac air flow to Air condition HVAC units; by keeping its position due to stability of the plastic frame. An air filter pad inserted inside A plastic ac case housing.

SUMMARY OF THE INVENTION

The present invention is an air filter pad inserted inside A plastic ac case housing to sustain and secure filters in position for better AC HVAC airflow. The present invention is a built-in plastic frame with most to all sizes to fit AC HVAC units. Size Examples (in inches): 20×20×1, 21×23×1, etc. . . . .

The use of the PLASTIC AC FILTER CASE WITH FILTER TO EXCHANGE is to save the case and to exchange the filter pad inside after getting dirty or worn out. The PLASTIC AC FILTER CASE WITH FILTER TO EXCHANGE will hold its position and be used as a secure storage body for the filter while AC HVAC operates. Further, according to the present invention, the uniqueness of this invention is that it's a filter case that holds and exchanges air filter pads, which will be cut to exact size to fit inside the plastic case that's a perfect fit to AC HVAC unit filter size. Because of the plastic frame structure, the PLASTIC AC FILTER CASE WITH FILTER TO EXCHANGE will stop dirt from getting to the HVAC system.

Unique Filter Pad: (Subject to Claims)

Made from fibers, polyester or hog hair cut to fit pads_includes but not limited to different colors, different smells, use abilities, different air and dirt ratings.
