Using A Dehumidifier In Indoor Pools And Spas. Some of you may be unaware of how to prevent mold from forming in your swimming pool or spa. If you have an indoor pool or spa it is likely that you need to keep it at an optimal humidity level for maintaining quality and integrity. Mold, mildew, algae, and other types of growth can begin to form if there is too much moisture present. Mold can cause irritation and respiratory problems such as asthma, allergies, bronchitis, and more severe conditions such as pneumonia.

It’s important to take care of these issues before they start by using a dehumidifier in indoor pools & spas. When used properly a dehumidifier will help maintain humidity levels within 15% of recommended levels set by ASHRAE (American Society of Heating, Refrigeration, Air-Conditioning Engineers). This keeps mold from growing but also helps with energy efficiency because less energy will be needed to heat or cool air when it’s not necessary which saves money on utility bills every month.

Why do you need to use one?

Most indoor pools and spas aren’t designed to take in large amounts of water so humidity can be a problem. If humidity levels rise above 60% then mold, algae, and mildew can grow which will cause problems with your pool environment. Mold and mildew look ugly and is unhealthy for swimmers while algae growth interferes with sanitation processes causing disinfection by-products (DBPs) to build up which are toxic to swimmers. DBPs also irritate the skin and eyes, causing redness and irritation.

To keep your pool looking clean you need to reduce humidity levels below 60%. A dehumidifier is an easy way to do that as it takes moisture out of the air through condensation. The moisture from your indoor pool or spa is collected in a collection tray where it drips into a bucket underneath where it can be emptied away easily.

How to install it?

The best place to install your dehumidifier is directly above where you swim. By installing it above and across from your swimming pool, you’ll be able to suck up as much humidity as possible before it gets into the air. To make sure that your device isn’t sucking in dust and dirt, be sure to clean it regularly. Most models come with an included filter that can be easily removed for cleaning.

You should also check that there are no leaks around the hose or drainage system so that water doesn’t leak out of your pool instead of being sucked in by your dehumidifier. If you have any questions about how to use a dehumidifier properly, ask an expert at a local hardware store for advice on installation and maintenance.

How to operate it?

It is pretty simple to operate your pool dehumidifier. You’ll want to drain it every few days and then refill it with clean water. If you notice that your water is starting to look dirty and hazy, you’ll also want to add some extra chemicals. The first step in operating a pool dehumidifier is draining it off any water and wet debris from inside it. This will help keep any mold or mildew from growing inside of it. Then, when you are ready to use it again, just fill it up with fresh water and plug it back into an outlet.

If you have hard water in your area, be sure to check for mineral buildup on a regular basis as well as replace filters often. Depending on how much humidity there is in your area, you may need to run your dehumidifier daily or weekly during certain times of the year. Most people find that they need their pool dehumidifier running about once per week during springtime or fall months when there are no leaves falling off trees nearby.

How much it costs?

The average cost of getting a professional to install it is around $1,400.00 dollars. If you’re only planning on running it seasonally, then you might be able to get away with buying one for around $600.00 dollars and adding your own installation. Either way, there’s no way around it: They can be expensive. But if you have an indoor pool or spa that tends to be overly humid (which can lead to mold and mildew), it may be worth looking into.
