If you own an indoor pool, you know that it requires special care and monitoring to keep humidity levels in check. But you might not know just how important it is to make sure you're using effective, high-quality pool dehumidification equipment.


Many common issues that pool owners face arise from a common issue: the pool room is too humid. If your indoor pool humidity level is too high, you could end up with any number of the following problems in your facility:

Health Problems

If you're like most pool owners, you use chlorine to keep the water clean. What you might not know is that chlorine interacts with sweat and other organic material that swimmers bring into the water. This reaction produces chloramine gas, which can lead to respiratory issues and skin irritation for swimmers and anyone else who visits your pool room.


While this issue isn't directly caused by humidity, the two problems go hand in hand. Effective pool dehumidification equipment will replace the humid, chemical-laden air with air that is clean and fresh.


Humid environments also encourage the growth of bacteria and allergenic mold, both of which can have adverse health effects.

Uncomfortable Environment

No one likes to be in a humid environment. Humidity can make the air feel hot and sticky, even if the temperature isn't uncomfortably high. On top of that, the humidity can also create a breeding ground for mold and other unpleasant smells.

Damage to Your Facility

Over time, excess moisture in the air can lead to structural damage in your building. Without proper drainage, condensation can lead to mold and rot. You should also keep in mind that the same chloramines that cause respiratory problems for your guests can also cause the metal surfaces in your facility to rust and corrode.


These issues may seem extreme, but it's important to remember that this damage doesn't happen overnight. It's the result of high humidity levels over time. With the right dehumidifier, you can prevent these problems before they get out of control.

  • A ventilation system that's not functioning correctly: If you have a ventilation system in place already, there may be an issue that's preventing it from lowering the humidity. It could be the wrong size for your facility or it might simply be in need of repairs.
  • Facility construction issues: The ventilation in your facility might not be at its peak if the air ducts and vents aren't placed strategically. The wrong building materials can have adverse effects as well. Missing or broken vapor barriers can also let condensation build up in the walls if the humidity is high.
  • No dedicated dehumidification system: There's no getting around it — if you have an indoor pool, you need a dehumidification system. Without it, moisture in the air can quickly build up and create a stuffy and unsafe environment.
