Loose fit, smaller size

Filters are competitively priced, delivery was quick, quality is very good. My only complaint is the filter is approximately a 1/4" smaller in length and width as compared to the 3M and Honeywell filters I have been using. When installing in a ceiling mounted grille the filter wants to fall down while attempting to close the door. Standing high on a ladder and trying to hold the filter up and close the door at the same time can be challenging. Once the door is closed the filter drops down and lays on the back of the grille. When the fan comes on the suction pulls it up and then it drops back down when the fan is off. I don't know if this allows air to seep past the filter along the edges or not. Once I use the new filters I've already purchased I'll have to decide if I want to use them again or go back to 3M.
