Want the best dehumidifier for your indoor pool? Read this before buying.

A spa and indoor pool are the perfect places to relax.

It can be the right place to go when the weather heats up and air conditioners aren’t providing you with the comfort and relief you want. Besides relaxing, some people use spas as a way to rejuvenate and shed some energy. A pool can be both a relaxing place for you to relax and an excellent way to burn some energy if that is what you are looking for.

Indoor pools and spas require costly maintenance, however. Many factors determine a swimming pool’s quality, such as the building’s infrastructure, materials, water quality, and air moisture. 

It is not uncommon for a pool area or spa area to have high humidity levels.

A pool room’s increased humidity levels can cause substantial damage, however. In order to handle this, we need proper dehumidification systems.

Keep reading to learn why having the right dehumidifier for an indoor pool is good practice.

What should the humidity be in an indoor pool?

Ventilation, water evaporation, damp ground; are major contributing factors that lead to rising humidity levels in the pool environment. Both spa area and pool area are always higher than the room temperature and ideal humidity level.

This is because pool water and spa water are always heated to give the comfort the guests look for. When this happens, a large amount of water vapor is generated. This extra heat is why pool temperature is higher than in most homes. All spas, public swimming pools, or any indoor swimming pool are expected to maintain a relative humidity level of under 60%.

“It is recommended that you maintain it at 50 to 55% at 26°C during winters and 23°C during summers. When the humidity level in a pool room exceeds this level, one will begin to encounter mold problems and other signs of home damage.”

When you have an indoor swimming pool, it is crucial to ensure that your home is protected against interior damage, wood rotting, paint damage, metal corrosion, mold and mildew, health issues, musty or foul odor, and other problems that result from moisture becoming excess in the air and seeping into the building’s structure.

Keeping a check on this issue is easy by investing in a good indoor swimming pool dehumidifier unit and a humidistat. These units are excellent options that provide you with the necessary information on the present humidity level and temperature of your swimming pool.

What type of dehumidifier should be used for an indoor pool?

Indoor pool dehumidifiers are readily available to control the excess moisture and humidity in the environment. However, the reason why the pool environment is high in humidity is because of the poor dehumidification process. The problem arises when the air isn’t being ventilated thoroughly as it should be. Industrial dehumidifiers are the best options to handle the humidity in any indoor swimming pool.

The advantages and uses of an industrial dehumidifier for a swimming pool lie in the fact that they are sturdy and durable to withstand the erratic changes in pool temperature and humidity, they have their own ways of removing large amounts of water from large open spaces, they can be put to use to collect the evaporated pool water and replace them back into the swimming pool by setting up some simple hose connections.

FAQ Section

1. Do indoor pools cause mold

Yes! They do. Any place that is laden with moisture is a favourable habitat for mold growth. Indoor pool area that has a mold problem that is not taken care of will lead to health concerns like respiratory problems, skin allergies, rashes, eye infections, severe cough, and more. Having pool dehumidifiers installed will keep mold at bay by controlling the humidity.

2. Are indoor pools bad for your lungs?

It is a known fact that dehumidifiers make a lot of noise. The compressor, exhaust fans, and condensate pumps are vital contributors to the sound levels. On average, a home dehumidifier noise is rated around 55-60 dB, which is about the same as regular human speech sound level.

Some crawl space dehumidifiers tend to get noisier when the fan motor or compressor mounting brackets or screws become loose. This improper connection causes the fan or compressor to vibrate and become noisy. So whenever you feel that the dehumidifier in your crawl space has started becoming noisy, first unplug the dehumidifier and tighten any loose components. Even after tightening, if the noise increases, you may have to replace the fan or compressor.

3. How much to build an indoor swimming pool?

The exact cost to build an indoor pool will vary across each home; depending on the size of the pool, infrastructure, and the materials used. The cost range is found to be from $15000 up to $200 000.
