Proper Sizing of a TrueSTEAM Humidier
Converting square footage to cubic volume requires multiplying the square footage by the ceiling height
(i.e. 2000 square foot space with 10 foot ceilings is 20,000 cubic feet). In general, the higher the ceilings, the
smaller the square footage space each TrueSTEAM model will cover since it must humidify the additional air
volume.
INCLUDE ALL SQUARE FOOTAGE OF THE HOME. FINISHED AND UNFINISHED.
Example 1: 2000 sq ft home: 8 ft ceilings = 16,000 cu ft. (2000 x 8)
Example 2: 2000 sq ft home: 10 ft ceilings = 20,000 cu ft. (2000 x 10)
Example 3: 2000 sq ft home: ½ with 8 ft ceilings, ½ with 12 ft ceilings. = 20,000 cu ft. ((1000 x 8) + (1000 x 12))
INCLUDING CEILING HEIGHT, FINISHED AND UNFINISHED SPACE WILL PROVIDE A MORE ACCURATE
SIZING FOR HUMIDIFICATION.
