How Often Do You Change an Above Ground Pool Filter?

Maintaining your above ground pool filter is one of the most important tasks you need to do to keep your swimming pool clean and healthy. It is required that you keep the filter clean at all times to make sure it is functioning optimally. But, how often do you actually need to change the filter? Keeping your above ground pool filter in top shape is easy, and here’s a guide on how to maintain them and when to replace them.

What is an Above Ground Pool Filter?

Before we dive into how often you should change your above ground pool filter, let’s first take a look at what a pool filter is. The pool filter is responsible for keeping your pool clean by removing dirt, debris, and other contaminants from the water. In essence, it is designed to keep your water safe to swim in. The filter helps to keep the water clean so that you can enjoy swimming without worrying about harmful bacteria and other contaminants.

Types of Above Ground Pool Filters

There are three most common types of pool filters for above ground pools: Sand Filters, Cartridge Filters, and DE Filters. Each filter type has different requirements when it comes to maintenance and replacement.

Sand Filters

The sand filter is the most commonly used filter for above ground pools. They are easy to use, reliable and affordable. These filters have a multiport valve that can help you select different functions such as filtering, backwashing, or rinsing.

Cartridge Filters

Cartridge filters are an alternative to sand filters that use a disposable element cartridge to filter the water. These filters are great for people who prefer low maintenance products.

DE Filters

DE filters are the most efficient type of pool filter available. They use a powder called diatomaceous earth (DE) to remove impurities from the water.

How Often Should You Clean Your Above Ground Pool Filter?

To keep your pool filter clean, it is recommended that you clean it at least once a week or after every use. Cleaning the pool filter depends on the type of filter you are using. Here are some general tips for cleaning your above ground pool filter:

Sand Filters

Sand filters should be backwashed once a week. This process removes dirt and debris from the pool filter. Once a year, you should dismantle the sand filter and replace the sand.

Cartridge Filters

Cartridge filters should be hosed down once a month to remove excess dirt and debris. Depending on the usage of the pool, you may need to replace the filter cartridge every six to twelve months.

DE Filters

DE filters should be backwashed and cleaned every month. You should replace the DE powder at least once a year.

When Should You Replace Your Above Ground Pool Filter?

Despite the cleaning process, there will come a time when you need to replace your above ground pool filter. Some tell-tale signs that your pool filter needs replacement include low pressure, cloudy water, higher chlorine levels, and clogs.

Low Pressure

If the pressure gauge reads low, it means that the pool filter is not working efficiently. The low pressure may indicate that the filter is clogged and no longer able to filter debris from the water.

Cloudy Water

Cloudy water in the pool can indicate that the pool filter is not doing its job correctly. This can be caused by a dirty or old filter that needs replacement.

High Chlorine Levels

If your pool filter is not doing its job, you may need to add more chlorine to the water to kill bacteria and other contaminants. This can happen because your filter is old and needs replacement.

Clogs

If you notice that the pool filter is clogged or has a buildup of debris, it may be a sign that you need to replace it. A clogged pool filter is a sign that the filter is no longer functioning efficiently and needs replacement.

Conclusion

In conclusion, keeping your above ground pool filter clean is easy, and routine maintenance includes cleaning it once a week or after every use. However, if your pool filter is showing signs of wear and tear, such as low pressure, cloudy water, or a buildup of debris, then it’s probably time to replace it. So, to ensure safe and enjoyable swimming, it’s always best to keep a check on your filter’s lifespan and replace it when necessary.
