A grand Dampp-Chaser ($810 + tax) includes humidistat, 2 dehumidifier bars, and humidifier with smart heater bar. The owner must "water" the piano every two to three weeks and service it annually to keep the system clean and working optimally.

An UnderCover (small $260 + tax, medium $265 + tax, and large $280 + tax) doubles the grand system’s efficiency by buffering between the ambient atmosphere and what the humidifier and dehumidifiers work to provide under the soundboard.

An upright Dampp-Chaser ($720 + tax) has similar components to the grand system but works from inside the piano's case, with no need for a covering. An UnderCover may be added as a back cover, though, if room heater proximity is a problem.
