How it works

Use a broad pints-per-day range based on area and perceived dampness.

Simple example

A damp 500 sq ft room may start around a 20–30 pint/day model.

Common question

Does this solve water problems?

No. Find and fix leaks or water entry; capacity alone does not address the cause.

This is a planning estimate. Check product instructions, dimensions and site conditions before purchasing or building.
