Important parameters that decides the size of the dehumidifier

Room size: Measure your room size and number of doors and windows.

Target Humidity:  Know your target humidity

Room Temperate: This will play major role, we always recommend maintain certain temperature in the room to maintain certain humidity. RH varies with room temperature.

Sources of Moisture: If you have open water sources like pool of water or material with moisture than you need strong dehumidifier.

How well room is sealed: Please make sure sufficient fresh air enters in to room, otherwise oxygen levels will reduce in the room depending on number of persons in the room.

No of persons working in the room: Each person in the room emits 3 to 6 Liters/Day depending on the work  he is doing.  This is one of the important perimeter to be considered while selecting the dehumidifier.

How many times door openings/Hour:  If number of door opening are more outside air enters in to room, that will increase the moisture in the room if out side humidity is more.

Any other sources of moisture in the room: For example moisture from material, swimming pool or moisture due to cooking etc.
