Let’s size dehumidifier for your home.

To select the right dehumidifier capacity, first, you need to decide room size. Thereafter, you can identify the current humidity level in the room. you need to follow this chart.

Measure room for dehumidifier sizing.

Measure the size of the room which you want to dehumidify. For this, you can use rough measurements also. The type of AC design is important. If space has separate AC then it is simple. If the same AC shared with two rooms then consider areas of both rooms.

Considering the total covered area by AC is an important aspect. Failing to it, you might do wrong dehumidifier calculation.

Decide the area type for a dehumidifier calculation.

Depending on symptoms of high humidity, you can identify area type. As mentioned before, these symptoms are like a bad smell, wet floor, etc.

You need to decide if your room is moderate damped, very damped, very wet or extreme wet. Based on these two data, from the chart, you can decide dehumidifier sizing.

Example of dehumidifier calculation.

Let’s consider that you have a room of area 1000 sq. feet which need to dehumidify. Also, AC is common between this room and another room. Another room has an area of around 500 sq feet. Also, consider that you are noticing a spot on the wall and wet floor due to high humidity. 

Hence your total area to dehumidified will be 1000 + 500 = 1500 sq.feet. So, we have to do a dehumidifier calculation for 1500 sq feet room.

And, your room condition falls is the “Very Damp” category.

So based on the chart, you need a unit having a capacity of 12.5 liters/day.
