Pool Filters 101: All The Basics You Need To Know In 2023

When looking for a pool filter, there are 5 basics you should consider before making your purchase.


  1. Size – The size of the filter is one of the most important factors to consider when buying a pool filter. You want to make sure it’s big enough to handle your swimming pool’s volume and capacity. If it isn’t, then it won’t be able to clean your water effectively or quickly enough.

  2. Filtration Level – Different filters offer different filtration levels depending on what type of debris they can remove from the water, such as dirt and debris particles, algae, bacteria, etc. Depending on the size of your pool and how often you use it, you’ll need different levels of filtration.

  3. Flow Rate – The flow rate is determined by the pump and filter system and affects how quickly the pool water is circulated through the filter. If your pool has a high-flow rate, then it will take less time to filter all the water in your swimming pool.

  4. Maintenance – Pool filters require regular maintenance to operate efficiently and effectively. This includes cleaning of the filter media, checking for clogs or blockages, and making sure that everything is running smoothly. You should also make sure to replace any parts that are worn out or damaged as they can affect the performance of your filter system

  5. Cost – Finally, the cost is an important factor when it comes to purchasing a pool filter. Depending on the size and type of filter, you could end up spending hundreds or even thousands of dollars. It’s important to research different options and find a filter that fits your budget and provides the filtration level you need.


By considering these 5 basics before making a purchase, you will be able to make an informed decision and ensure that you get the most out of your pool filter in terms of performance, efficiency, and cost-effectiveness.


3 Types Of Pool Filters – Which One Is Right For You?


  1. Sand Filters: These are the most popular type of filter and use a layer of sand to filter out particles from your pool water. The sand traps small debris, dirt, and other contaminants that pass through it. Water is then pumped back into the pool after filtration has taken place. It’s important to note that regular cleanings are required for these filters as they can become clogged over time with dirt and debris.

  2. Cartridge Filters: These have become increasingly popular in recent years due to their ease of maintenance and cost effectiveness compared to sand filters. Instead of sand, cartridge filters use a cylindrical filter element made up of pleated material which catches smaller particles than traditional sand filters. They are generally much easier to clean than sand filters, simply requiring a hose down or an occasional replacement of the cartridge itself.

  3. Diatomaceous Earth (DE) Filters: These use diatomaceous earth, which is a type of sedimentary rock rich in silica, to trap small particles from your pool water. DE is finer than sand and is able to capture even smaller particles that may pass through other types of filter media. The DE must be regularly changed out as it becomes clogged up with dirt and debris over time.
