I'm having trouble finding A/C return grilles that fit Filtrete Ultra filters.
The grilles supplied by my A/C contractor measure 1/2" short (the 20x20 is
19.5x19.5 internally) and the Filtrete Ultra is 19.75 square.
Does anyone know of a brand of grille that is actually the dimension that it's
supposed to be, without any of this 2x4 "close enough" size?

Thanks, Rick DeBay


This is Turtle.

There is something really wrong here with a 20 X 20 return air grill not taking
a 19.75'' x 19.75'' filter. all American manufactors of return air filter grill
make the filter area of a 20 x 20 return air filter grills , filter area will
be atleast 19 7/8" X 19 7/8" . they don't make them 19.5 " X 19.5'' at all. One
of two things here happen.

1] The contractor got stuck with some special order return air filter grill
that he ordered sized at 19.5" X 19.5 " and ring to pawn these odd ball filter
grills on you. Or the warehouse is Pawning them on him and he not know it at
all. In the HVAC business we have to order any different sizes of filter grills
for odd ball jobs and i have ordered 19.5" X 19.5" filter grill and can order
special order 19.5" X 19.5" filters to go in them.

2] The wall has shifted and mashed the filter grill to a point of it getting
smaller one way and it will be short one way and not the other. Measure both
ways and see. the filter grill can be crushed into a hole to a point of mashing
the filter grill to a smaller size.

if the hole where the filter goes masures 19.5" X 19.5" --- It is NOT a 20'' X
20'' filter grill like it was suppose to be. if you can't put real easy a
19.75" X 19.75" Filter in a 20'' x 20'' return air filter grill. you need to
bring the filter grill back to get the correct size that goes in it.

In Over 40 something years in the HVAC/R business I have never seen one
installed correctly, not a odd ball size filter grill to start with , that the
filter would not fit fine in the filter grill.

Something is just too fishy here ! Call the hvac contractor back and clear this
mater up.
