The ideal indoor humidity should be 35–45 %. Maintaining this humidity level can be a challenge without the proper humidifier or dehumidifier. A humidifier adds humidity to the excessively dry air, while a dehumidifier removes moisture from humid air.

Installed together with your HVAC system, dehumidifiers are useful in warm months to enhance indoor air quality. That said, a plumber in Park City is in the best position to advise you on the right dehumidifier for you. Depending on your needs, there are three types of dehumidifiers to choose from.

Absorption Dehumidifiers

This device extracts atmospheric humidity using sorbent materials. The material contains pores that absorb humidity. The vapor pressure of the sorbent material determines how much moisture your unit can remove. Low vapor pressure is ideal for efficient dehumidification. Absorption dehumidifiers are common in industrial and commercial installations and rarely in residential areas.

Spray Dehumidifiers

Also, known as air washers, these are only useful as long as the spray temperature is less compared with the HVAC unit’s air dew point. Condensation will not be possible for high spray temperatures. Air washers are typically useful in industries since they clean air in addition to removing humidity.

Refrigeration Dehumidifiers

These dehumidifiers remove atmospheric humidity by passing air over cooling coils. The coils cause air condensation. It then collects and discharges condensate to an exterior drain through a hose. For efficient dehumidification, the dew point of air coming into the system should be more than that of the air leaving the system. Refrigeration dehumidifiers are common in residential properties. The amount of moisture removed by these units depends on the level of humidity and air volume.

High atmospheric humidity creates a good environment for mold and mildew growth. The dampness of humid environments also has an unpleasant smell. Proper dehumidification is hence essential for a comfortable and healthy indoor environment.
