Order your convenience pack (1-year supply of 4 filters) and they will be shipped to you within a few days. Install the first filter, and we'll send you an email when it's time to replace it. At the end of the year return and re-order another pack.
DID YOU KNOW? - When sizing your filter, height and width are interchangeable because whether the register is vertical (portrait) or horizontal (landscape), the SealTite Filter will fit perfectly. For example, a 14" X 30" X 1" filter is the same size as a 30" X 14" X 1" filter.
