If you have ever taken a dip in a traditional chlorine pool, you are familiar with the strong smell and the way it can irritate your eyes or cause dry skin. Many pool owners are seeking ways to maintain their water’s cleanliness without relying heavily on harsh chemicals. That is where natural pool filters come in. They offer a safe, eco-friendly way to keep your pool crystal clear and healthy for swimming.
In Northwest Arkansas, where families enjoy spending time outdoors, natural pool systems are gaining popularity every year. These systems utilize plants, beneficial bacteria, and natural materials to filter the water, rather than relying solely on chlorine or other strong chemicals.
What Are Natural Pool Filters?
Natural pool filters are systems that use nature’s own processes to clean your water. Instead of adding a lot of chlorine or other chemicals, they rely on plants, gravel beds, and helpful bacteria to filter and purify your pool water. This process works much like a natural pond, where the water remains clear due to the balance between plants, bacteria, and the flow of water.
A natural pool typically features two distinct zones: a swimming area and a regeneration area. The regeneration area is where the magic happens. It contains plants like reeds, water lilies, and cattails that act as living filters. These plants absorb nutrients from the water, which prevents algae from taking over. Beneath the plants, layers of gravel and sand provide a surface for beneficial bacteria to grow. These bacteria break down impurities, such as sweat, sunscreen, and debris, and turn them into harmless byproducts.
This process is called biofiltration, and it is the same method that keeps lakes and ponds clean in nature. The water is circulated between the swimming area and the regeneration zone using a pump, so it stays moving and fresh. The result is clear, clean water that is safe to swim in without relying on chemical shock treatments.
Key Benefits of Using Natural Pool Filters
Health Benefits
One of the biggest reasons people switch to natural pool filters is health. According to the CDC, pool chemical injuries send about 4,500 people to emergency departments in the U.S. every year, and at least one-third of those injured are children. Without large amounts of chlorine, there are fewer skin irritations, no burning eyes, and no strong smell. This is especially helpful for families with children, pets, or anyone with allergies or sensitive skin.
Natural pools are also a great choice for families with children who have skin conditions like eczema. Chlorine can often make these conditions worse, while a chemical-free pool allows them to enjoy swimming comfortably. Pet owners love natural pools too because there is no risk if their dog drinks some of the water.
Eco-Friendly
Using natural pool filters is good for the environment. There is no chemical runoff that can harm plants, soil, or groundwater. You are also supporting a natural mini-ecosystem right in your backyard. Some systems even attract butterflies and pollinators, adding beauty and life to your outdoor space.
For homeowners in NWA who value sustainable living and want to protect the Ozarks’ natural beauty, natural pools are an excellent option. They help reduce chemical use and create a space that blends perfectly with the surrounding landscape.
Cost Savings Over Time
While a natural pool filter system may have a higher upfront cost, it can save you money in the long run. You spend less on chemicals, testing kits, and other maintenance supplies. Once the natural balance is established, the system mostly maintains itself, which means fewer trips to the pool store and lower ongoing expenses.
Low Maintenance
Many pool owners are surprised by how little work is needed once a natural system is set up. The plants and bacteria do most of the work for you. Of course, you will still need to skim leaves, check the pumps, and clean out any debris, but you will not have to constantly measure and add chemicals.
Better Swimming Experience
Natural pool water feels softer and more refreshing. You will not leave the pool smelling like chlorine, and you will enjoy a clean, natural look. Some natural pools even have water features like small waterfalls or streams, which add to the relaxing experience and make your backyard feel like a private oasis.
Alternatives to Traditional Pool Chemicals
Natural filters are not the only way to cut down on chlorine use. Here are other great options if you are looking for a healthier pool in NWA.
Saltwater Systems
A saltwater pool uses a special generator to turn salt into a small amount of chlorine. This keeps your pool sanitized but with much softer water and a lower chlorine level. Many pool owners say it feels better on their skin.
Pros: Gentle on skin, less smell, less maintenance.
Cons: Higher upfront cost for the generator, salt can be corrosive to some pool equipment.
UV Pool Sanitizers
Ultraviolet light can kill bacteria and other harmful organisms in your pool water. A UV sanitizer works alongside your main filter and helps you use fewer chemicals overall.
Pros: Reduces need for chemicals, very effective at killing germs.
Cons: Requires electricity and regular bulb replacement.
Ozone Pool Systems
Ozone is a natural gas that is a powerful oxidizer. It breaks down bacteria, algae, and other contaminants quickly. This means you can cut your chemical use by up to 90 percent while still keeping your pool safe.
Pros: Powerful sanitizer, works quickly.
Cons: Higher upfront cost, ozone equipment needs professional installation.
Mineral Filters
Mineral filters use silver and copper ions to fight algae and bacteria. They are often paired with very small amounts of chlorine or other sanitizers for a complete solution.
Pros: Lower chemical use, natural approach.
Cons: Still requires some chemical backup.
Hybrid Systems
If you are not ready to go fully natural, you can use a hybrid system. This combines a natural filter with a low-level sanitizer, giving you the benefits of both worlds.
Things to Consider Before Switching
Before making the switch, think about your space, budget, and lifestyle.
- Installation cost: Natural systems can cost more upfront, but you save money on chemicals later.
- Space needs: Plant-based natural pools need a regeneration zone with plants, so you need enough yard space for this.
- Maintenance: While natural pools are low-maintenance, they do need seasonal care. Plants may need to be trimmed, and gravel beds need to stay clean.
- Professional help: Work with a pool expert in NWA to make sure your system is designed correctly so your water stays clear and safe.
