Owning a pool is a dream for many homeowners—a place to relax, entertain, and escape the heat. But as any pool owner knows, it’s not all sunshine and fun. Pool maintenance is a significant responsibility, and one of the most common systems used to keep pools clean and safe is chlorine.
While chlorine has been a reliable method for decades, it’s not without its downsides. If you’re a pool owner—or considering becoming one—you might be wondering if a chlorinated pool system is truly the best choice for you.
In this article, we’ll explore the hidden downsides of chlorinated pool systems so you can make an informed decision about your pool’s maintenance.
We believe in providing our customers with all the information they need to make the best choice for their specific situation. While we install chlorinated systems because they are effective and widely used, we also recognize that they may not be the perfect fit for everyone. Our goal is to ensure you have a clear understanding of both the benefits and the potential drawbacks, allowing you to choose the best pool maintenance system for your needs—whether that’s chlorine or another option.
Chlorine is widely used in pools because of its effectiveness in killing bacteria and controlling algae. It works by breaking down into various chemicals, including hypochlorous acid and hypochlorite ion, which destroy harmful microorganisms in the water. This process keeps the water clean and clear, making it safe for swimmers.
But while chlorine might seem like a convenient and effective solution, it’s essential to consider the downsides, especially if you’re prioritizing your family’s health, comfort, and long-term maintenance costs.
One of the most common complaints among pool users is irritation of the skin and eyes. Chlorine can be harsh, especially in higher concentrations, causing redness, itching, and dryness. For people with sensitive skin or allergies, swimming in a chlorinated pool can be particularly uncomfortable. If this sounds like you, your best friend is the Oxygenated Pool System.
Chlorine doesn’t just affect your skin and eyes; it can also impact your respiratory system. When chlorine reacts with organic matter in the pool—like sweat or urine—it forms chloramines, which can evaporate into the air and be inhaled. This can lead to respiratory problems, especially for individuals with asthma or other respiratory conditions.
There is ongoing debate about the long-term health effects of frequent exposure to chlorinated water. Some studies suggest a possible link between chlorine exposure and certain types of cancer, though the evidence is not yet conclusive. However, it’s something to consider if your family spends a lot of time in the pool.
When pool water is backwashed or drained, the chlorine and other chemicals in the water can end up in local waterways, potentially harming aquatic life. Chlorine is toxic to fish and other aquatic organisms, and even small amounts can be dangerous.
The production of chlorine itself is not without environmental consequences. Chlorine is produced using a significant amount of energy, contributing to greenhouse gas emissions. Additionally, the transportation and storage of chlorine requires careful handling due to its hazardous nature, adding further to its environmental impact.
Maintaining a chlorinated pool is not a “set it and forget it” task. Chlorine levels need to be monitored regularly to ensure they are within a safe range. If the levels are too low, the water becomes unsafe to swim in. If they’re too high, it can cause the irritation issues we discussed earlier.
It’s easy to accidentally add too much chlorine, especially when trying to compensate for heavy pool usage or a sudden algae bloom. Over-chlorination can lead to an increase in chloramines, which, as mentioned earlier, can cause respiratory problems and make the pool water less comfortable to swim in.
One of the most recognizable downsides of a chlorinated pool is the smell. The “chlorine” odor often noticed around pools isn’t actually chlorine itself but chloramines—the same compounds responsible for skin and eye irritation. This smell can be off-putting, particularly in enclosed pool areas.
When it comes to maintaining a clean and safe swimming pool, chlorine is just one of many options for keeping your swimming pool clean and safe. There are several alternative pool systems available, each offering unique benefits that might better align with your specific needs. Exploring these options can help you determine if one of them is a better fit for your pool.
Oxygenated Pool SystemOxygenated pool systems, also known as “Oxygen pools”, use oxygen in combination with a small amount of chlorine or other sanitizers to keep the pool clean. These systems generate active oxygen (O₃ or O₂) through a special reactor, which helps to oxidize contaminants in the water, providing a natural and powerful sanitation method. | |
Pros | Cons |
| Extremely low chlorine use, natural and gentle on skin and eyes, effective at maintaining water clarity. | Higher upfront costs, requires specialized. |
Saltwater Pool SystemSaltwater pools have become increasingly popular as an alternative to traditional chlorinated pools. These systems use a salt-chlorine generator to produce chlorine from salt, which means the chlorine levels are generally lower and more stable. This can result in less irritation and a more comfortable swimming experience. | |
Pros | Cons |
| Lower chlorine levels, reduced skin and eye irritation, softer-feeling water. | Higher initial cost, more complex maintenance. |
Ozone Pool SystemOzone pools use ozone gas to purify the water, significantly reducing the need for chlorine. Ozone is a powerful disinfectant and can kill bacteria and viruses more effectively than chlorine alone. | |
Pros | Cons |
| Minimal chlorine use, excellent water clarity, and reduced odor. | Higher upfront costs, requires professional installation and maintenance. |
UV PoolsUV pool systems use ultraviolet light to kill bacteria and other pathogens in the water. While UV systems still require some chlorine, the amount is significantly reduced, leading to fewer of the downsides associated with chlorine. | |
Pros | Cons |
| Low chlorine levels, effective sanitation, and minimal environmental impact. | Higher installation and maintenance costs, and UV bulbs need regular replacement. |
At the end of the day, deciding whether to stick with a chlorinated pool system or explore alternatives depends on your priorities.
If you value low upfront costs and ease of use, chlorine might still be the best option for you. However, if you’re concerned about health impacts, environmental effects, or just tired of the constant maintenance, it might be worth exploring oxygenated pool systems, saltwater systems, ozone systems, or UV systems.
You now understand the hidden downsides of chlorinated pools, from health risks to environmental concerns.
If you’re feeling frustrated by the irritation, the smell, and the maintenance, remember that there are alternatives out there.
