What size filter do I need?

SafeHome Filters are designed to replace many standard size filters in home air systems. To determine the size you need, look for the size on your current filter, typically written on the side of the filter. If you cannot find this size, simply measure and use the closest inch. Filters are typically a little smaller than the stated size so that they will fit in most systems. For example, the exact dimensions of a 16x25x1 filter is actually a little smaller than 16″ x 25″ x 1″. SafeHome Filters are made for replacing 1″ deep filters.
