1. Many
grills have obstructions such as stop tabs, rivets and screws. You want to
make sure you take your measurement from in between these objects and subtract
1/4 inch, so the air filter will fit between them when you put it in.
2. Because our air filters
feature a patented form fit seal, the filter does not have to fit edge to
edge tight. As long as your measurement is larger then the inner lip of the grill, your
filter will seal properly. Leave yourself room to remove and re-install it
easily.
3. Always open the air filter
grill to take the measurement, don't assume the inside measurement is the same as
the outside.
4. Do not take your
measurement from your throw away type air filters. many times the size listed on
those filters is a nominal size and not the size of the actual filter.
5. Our air filter's frame is
made of sturdy aluminum and will not bend.
6. Take your time. Get
it right, you'll never have to do it again, these air filters last a lifetime!
