Pool Room Dehumidification Systems Frequently Asked Questions

  • Do I Need a Dehumidifier for My Indoor Pool Room?
    Pool rooms, which house large bodies of water, contain much higher humidity levels than those found within the typical residential/commercial building. If not properly controlled, when air becomes saturated (100% humidity) damage can occur to structural components and pool room equipment. Worse, such high humidity levels are not only uncomfortable, but create a breeding ground for mold, mildew, bacteria, and other organisms. Proper dehumidification safeguards the indoor air quality, protecting the health of pool room occupants, and ensures the longevity of the pool room structure and furnishings.
  • Why Isn’t Outside Air and an Exhaust Fan Enough?
    While ‘Waste Ventilation Systems’ can exchange air, they do not offer sufficient pool room humidity control over the course of the year, such as when conditions are humid in the summer, or rainy for an extended period of time in the winter and spring.
  • How Can I Tell if I Need to Upgrade or Replace My Current Dehumidification System?
    Look for these commercial humidity control issues as signs your current dehumidification setup is not up to the task:


    • Corrosion or rust
    • The presence of mold
    • Dripping windows
    • Stained or wet drywall
    • Caving ceilings
  • Will a Pool Cover Reduce the Need for Dehumidification?
    Pool covers do not reduce the need for dehumidification or the size of the system.
  • What is the Ideal Humidity Level for My Pool Room?
    HVAC commercial contractors recommend keeping relative humidity levels in the 50-60% RH range to maintain occupant comfort as well as the integrity of the building and components.
  • What is the Ideal Temperature for My Pool Room?
    For recreational pools, a setting between 75-85-degrees F is best. However, for rehab/retirement centers, diving centers, or other unique situations, these temperatures may be different.
  • What Size Dehumidification System Do I Need?
    It is essential to look to experienced commercial HVAC contractors in NJ when determining system size due to the number of factors that come into play for each unique pool room setup (size, ceiling height, climate zone, insulation, tightness/leakage in the building envelope, preferred temperature, pool heating setup, etc.).
  • Can I Use a Dehumidification System with a Salt Water Pool
    Most dehumidification units work with salt water pools.
  • Should Air Be Directed at the Pool Surface?
    Air movement speeds evaporation of pool water. Rather than directing air at the surface, using a return grill near the surface of the pool is preferred to control the chloramine layer and improve air quality.
