A pool filter is a very important part of a pool and to make sure it’s working to optimal performance is absolutely necessary for a clean and sparkling pool. Dirt and contamination can be brought into your pool by the wind, swimmers, and even pool toys. There are a few different types of pool filters including Diatomaceous Earth Pool Filters, Cartridge Pool Filters, and Sand Pool Filter.
Sand Filters are basically large tanks that are filled with a special kind of sand specifically for pool filters. Then the pool water is pumped through the sand inside the tank, where it filters out any particles before the water is returned to the pool. Once the particles build up inside the tank, you can backwash it to flush out the filter.
Cartridge Filters are tanks, only slightly smaller than a sand filter which has a cartridge filter inside it. The water is filtered through the cartridge where it collects the particles. To clean the filter, all you have to do is remove the cartridge and spray it with a garden hose.
Diatomaceous Earth Filters (D.E Filters) are big tanks that have fingers or grids inside it which are covered with a D.E powder. This power acts a little like sand but is more effective, and the pool water is filtered through it. To clean you have to backwash the filter and add new D.E powder.
However, it can be difficult to know what filter is the best to suit you and your pools needs. It all depends on the kind of pool you have and the requirements you need for the pool filter. The size of the filter is the one thing that determines how well it will perform no matter what size the pool is.
We have provided this helpful guide to show you the best pool filters on the market and help you to decide which is best for your pool.

There are so many different types of pool filters on the market, it can be difficult to know which one is right for you. While you start to look for a pool filter, you should keep some things in mind so you can gain the best filter for your pool.
- The first step is to work out which type of filter system you need for your pool, whether it’s sand, D.E, or cartridge. They all have their benefits, and their drawbacks, but once you recognize which one would suit you and your pool best, you can start looking into that type of pool filter.
- Another is to consider what kind of dirt and debris get stuck in your pool. Is it only leaves, dirt and twigs? Or smaller impurities? The word ‘micron’ is used a lot when researching pool filters and these are the main particles that your filter system will work to clear your pool of.
- One other important thing to consider before buying a filter is choosing the right size for your pool. You’ll need the right sized filter in order for it to work at optimal performance. Some might recommend buying a filter that is bigger than you would normally buy to fit your pool. This means you will have more surface areas and longer periods of time between cleaning the filter.
- Probably the most obvious and important benefit to having a pool filter is the removal of dirt and impurities in your pool. As you swim the water washes dirt and particles from your body, leaving them in your pool. A filter system works to draw the water in and catch these particles, so you don’t have to swim in a dirty pool.
- If the filtration of the water goes through in a gentle cycle, it is less likely that you will need to add more chemicals to the water in order to disinfect it as this is already being done for you. This means you are not wasting money or products or swimming in an overly chemically rich pool.
- Similar to the first point, a filtration system will clear your pool’s water, so you aren’t swimming in cloudy or green water. This makes the swimming experience must more enjoyable and keeps your pool looking brilliantly clean and crystal clear.
- Having a filter system means you don’t have to use excess energy to clean the pool yourself, taking time out of your day and using your own elbow grease to clean the pool manually. This means you get to spend your time actually enjoying your pool while your pool filter does all the work for you.
- These pool filters are easy to maintain, adding to the last point, meaning you don’t need to clean it all the time, depending on which filter you choose. Once installed they work hard to keep your pool consistently clean so you don’t have to worry about it. Just clean the filter every now and again so it can keep doing its job.
In conclusion, there are many pool filters to choose from and we understand how difficult it can be to know what one you might need to fit your pool requirements. You can choose from sand, D.E, or cartridge, each with their own benefits.
A sand filter is cheap to buy and maintain, is very effective in cleaning medium to large debris, known to be reliable for a long time, and the sand only needs replacing about every 5-7 years. A cartridge filter has very easy maintenance, no need to backwash, a much larger filter area, and saves energy and water while working. A D.E filter gives the best result in clearing the water, the powder is refillable through a pool skimmer, and it’s a reliable system for a very long time.
Each of these filters are designed to work well in any type of pool but looking at the benefits of each one you need to decide which is best suited for you. Perhaps the Hayward ProSeries Sand Filter with its anti-corrosion and weatherproof material and durability is the best option? Or the Pentair Clean and Clear Cartridge Filter with its huge filter capacity and 100% draining port? Or the Hayward Vertical D.E Pool Filter with its Perma Glass XL material and advanced features is the one for you?
Either way, a pool filter is the best option for maintaining your pools sparkle and removing the impurities from it for a more enjoyable swimming experience. Buying and installing one means you don’t have to do the grunt work or add any extra chemicals to the pool. Most models are easy to install and easy to use and free up your time to do whatever you want while it works.
When buying a pool filter remember to keep in mind some of the things we have covered so you can have a pool filter that works in tandem to your pool and fits it perfectly. Keep in mind the size of your pool, the size of the debris, and the size of the filter you need.
