FAQ

Those who are looking for an answer to the question «At what humidity do evaporative coolers stop working?» often ask the following questions:

❗ Do evaporative coolers increase humidity?

  • Under a hot and humid weather, an evaporative cooler cannot provide similar thermal comfort. In fact, because it increases humidity in the air, it can actually increase discomfort. There is also a need to use this electric appliance alongside exhaust ducts or open windows, or in the open air to maximize its efficiency.

❗ At what dew point do evaporative coolers stop working?

If you want to gauge a cooler's efficiency in terms of dew point, just keep in mind that, in general, a dew point in excess of 55 is generally a swamp cooler humidity limit.

❗ At what humidity do evaporative coolers become ineffective?

According to USA Today, “When the outside temperature soars to 100 degrees (38 C), we're in trouble if the humidity is much above 25%.” As temperatures rise, humidity must decline in order to effectively cool your home.
