What Is A Salt Water Pool Filter? [Facts!]

Spread the love

Most people take their pools for granted. They use them every day, so they assume they will always work well enough. While it’s true that most traditional pools will function efficiently for years of use, sometimes there is a need to enhance their performance a bit. In some situations, the filtration system is less than ideal, and it’s not uncommon for some pool owners to investigate and upgrade their SWPF systems every few years due to this.

What Is A Salt Water Pool Filter?

The name is enough to make any pool owner or renter suspicious. After all, most people assume that their pool already contains enough salt for all fish and swimsuit wear. If you’ve ever been to the pool’s edge during the summer and looked down, you may have noticed that the water isn’t as clear as you’d like it to be. This is usually caused by some particles that wind up suspended in the water, causing it to cloud up. These particles can range from tree pollen to dust from the air, and they’re usually small enough for the filter to catch.

This is why most people choose to use a salt water pool filter. The most notable benefit to using these systems is that they can reduce or remove these small suspended particles, which makes the water much clearer. This in turn makes it ideal for both fish and snorkeling, as well as making the pool a more refreshing place for swimmers.

However, it’s important to note that just because the water is clear doesn’t mean it’s good for your health. Too much salt can still be dangerous to your body, particularly if you have heart disease or diabetes. In these situations, getting a salt water pool filter is not advised.


In most cases, traditional pools will require replacement of the filter media, or the whole unit, every year or two. This is mostly due to the fact that the filter is only designed to filter water, and not prevent the pool from being drained by using a pump. Without this precaution, all the water would rapidly drain from the pool, causing it to become useless and in need of major maintenance.

Most people assume that a salt water pool filter will last much longer than a regular one, primarily due to the fact that it’s designed to filter small particles out of the water. However, this is only partially true. While it will catch smaller particles, it won’t be able to keep up with the flow of water through it, causing the need for replacement sooner than expected. This doesn’t mean that all salt water pool filters are created equal, as there are several high-quality pump-protected filters that can last for many years of heavy use without requiring any special attention or maintenance.

It’s also important to remember that the shape and size of your pool will have an effect on how long the filter will last. Pools with smooth or rounded corners will wear out the filter faster than ones with sharp corners or straight walls. In addition, if your pool is large compared to the size of the filter, it will be more likely to require replacement sooner than expected. This is especially true if the filter gets clogged with sediment from the pool’s floor, or it starts shedding hair. In these situations, it’s better to enlarge the pool than to try and fix the filter.

What Type Of Salt Do You Need?

There are several different types of salts that you can use to make your pool water clearer. Each one has its perks, but there is a catch. If you use the wrong type of salt, you may end up with degraded water quality, and this is certainly not what you want. The general rule of thumb is once the water has been sitting for a while, any type of salt will do, but you should use table salt for the first few hours until the water gets properly mixed and breaks down all the remaining chlorine from swimming pools and dishwashing fluids. After this, you can use whatever type of salt you want.

Although most people use table salt for this purpose, it’s still a good idea to read the ingredients on the packaging before using any type of salt. Some brands of salt contain iodine, which can cause problems for people with thyroid disorders or those who are already taking medications that increase their thyroid levels. If you’re not sure whether or not your medications are going to be problematic for your pool, it’s best to stay away from them.

Cleaning The Filter

Even after all this time, there are still several things that you need to do to keep your salt water pool filter clean. The first step is to occasionally remove the top piece, or shower cap, to clean it. Some people prefer to use a hose, or even run it under the hot-tubs faucet, to spray and clean their salt water filters. After this, you can either wipe it down with some paper towels, or simply replace the shower cap and let it air dry.

In some instances, this is all that’s needed. However, if there is some sort of mildew, or algae, growing in the shower cap, this will require more than just a simple clean. In these cases, it’s a good idea to replace the whole filter, as this will help ensure that all the water stays clean and unclogged, preventing all sorts of issues and headaches down the road. This is why it’s important to keep up with maintenance and cleaning of your salt water pool filter, so that you get the most out of it, and so that you don’t end up with any problems that are caused by an unclean filter.

While we’re on the topic of cleaning, it’s also important to remember that the type of water that you use for your pools will affect how clean it stays. For instance, hard water will quickly become cloudy, and sediment will accumulate at the bottom of the pool, requiring constant cleaning during peak hours. Using soft water will maintain the clarity of your pool, and it will also prevent all sorts of problems caused by mineral deposits. Even the type of lighting that you use in your pool can affect its clarity. If possible, go for a full-spectrum lamp, as these will emit less energy than ones that are not specific, which in turn decreases the amount of damage being done to the environment by using them.

Why Should You Keep Up With Maintenance And Cleaning?

It’s not always easy to determine how long your salt water pool filter will last, mainly due to the fact that this depends on several variables. The first one is how often you maintain it. It’s best to empty and clean it at least once a week during peak hours, and it should be done on a regular basis regardless of whether or not you use a pool filter. This will help keep the water crystal clear, and it will prevent many potential problems that could arise from stagnant water or unhealthy bacteria growing in it. If you wait until the last minute to clean your filter, this could cause serious damage to your pool, as there is rarely enough time to completely flush it, and it gets filled with more sediment the more frequently it’s cleaned. Therefore, it’s important to remember to always keep up with the maintenance and cleaning of your pool’s filter to get the best out of it.

How Do You Transport It?

You’ll need a place to store your pool, and there are several different ways that you can do this. If you have a certain amount of space, you can build a deck around it, and this is a very popular choice, as it provides the necessary storage while also giving you a place to sit and enjoy the pool. Another option is a pool shed, which is essentially a freestanding building that houses the pool equipment, including the filter. While these can be very durable, depending on the type and quality, they can also be a little on the heavy side, and it’s not always easy to transport them wherever you go. This is why many people choose to store their pool in a garage, which can be a space-saving solution, as well as providing you with some protection from the elements, if the garage is surrounded by houses on all sides.
