A backyard pool is often seen as the perfect warm-weather escape — ideal for relaxing, exercising, or entertaining. But pool ownership comes with more than just leaf skimming and pH testing. One commonly overlooked concern is how pool chemicals can affect the air you breathe, especially close to the water’s surface. When pool chemistry is off-balance, the effects extend beyond cloudy water or skin irritation. Chemical reactions can release airborne byproducts that may impact respiratory health. Whether you're handling maintenance yourself or relying on a service, it's important to understand how pool upkeep can influence the air around your pool — and your lungs.
