We fix indoor swimming pool air.

"A prescription without diagnosis is malpractice." - Unknown

Before throwing money at your pool's air quality problem, shouldn't you first properly diagnose why you have the problem? Symptoms of bad air quality are in almost every indoor swimming pool. You're not alone if you have rust all over the place, the 'chlorine pool smell', or people coughing and complaining. But fixing symptoms rarely prevents the underlying disease.

That's where we come in. We offer in-person facility studies to diagnose your pool's underlying problem(s). Our facility evaluations come with a detailed report and recommendations for solving the issues. For new pools, we also assist design professionals in preventing chloramine problems before they start.

Chloramine Problems

Every swimming pool requires a primary sanitizer–usually chlorine–to keep the water clean and safe. When people use swimming pools, however, chlorine can become overwhelmed with bather waste. Bather waste is usually carbon or nitrogen-based, and left alone, chlorine must oxidize these contaminants out of the water. While chlorine is an excellent, efficient sanitizer, it is not a great oxidizer. As a result, byproducts emerge from chlorine doing its job...primarily when it tries to oxidize nitrogen-based contaminants (like ammonia in sweat and urine). There are hundreds of known disinfection byproducts (DBPs) that off-gas out of a swimming pool; one of which is Nitrogen Trichloride (NCl3), more commonly known as Trichloramine. Mark Rober explains it really well on his YouTube channel:

For simplicity's sake, we in the industry usually refer to all of these off-gassing DBPs as "chloramines". Chloramines are a tricky thing to design for if you are a mechanical engineer or architect, because they do not behave like normal air. Thus, we created Chloramine Consulting to help clear the air. We know how to do it, and we know it takes a coordinated approach involving both water chemistry and air physics.
