The premium kit
Quick answer
A paid planning kit is in preparation. Nothing is for sale here yet, and everything needed to size and cost a setup is already free on this site.
In preparation
A printable planning kit is being put together: the sizing worksheets, the filter cost tables and the room by room record sheets in one document. It is not available yet and there is nothing to buy on this page.
What is already free
The sizing calculator, the five year filter cost calculator and the complete shopping list cover the whole job between them. The kit will be a convenience rather than a gate.
