You may not need that either, as most decent manufacturers use standardized

To an amusing extent.
Last year when I decided it was time for a filter for drinking water,
I found that the unit with two high end filters was more expensive
than the unit with two low end filters plus two replacement highend
filters.
High and low end filters have identical interfaces, and the unit they
mounted into was the same except for the sticky label.
