Just what I needed
It is very difficult to buy the decent filters for my furnace in Canada. It is almost impossible to find something above MERV 10 and of exactly the right size. Not to mention the insane price. Even my HVAC contractor installed the filters that were smaller than the opening, padding them on the sides with self-adhesive foam. This filter is just what I needed, fits the opening perfectly leaving no gaps. Will get back for more when the time comes to replace them.
