Do you have an inground pool in your backyard? Are you planning to install one?

You’ll learn everything you need to know about buying a pool filter kit as well as what buying the pieces on their own can accomplish, and you’ll even get a quick crash course in the different varieties available, too.

After that, we’ll introduce you to 10 of our top picks for the best inground filter systems you can buy. Whether you’re looking for sand, DE, or cartridge style filters, you’ll find plenty of options in our list below. And if you’re wondering what our number one choice is, just read on and find out!

Now, let’s get started learning about inground pool filter systems.

Inground Pool Sand Filter Systems

If you ask anyone about upgrading your inground pool filter system, chances are good they’ll recommend going with a sand filter. Sand filters tend to fall in the mid-range of prices for the three most common types of pool filters, and they offer a lot of power and many years of use without having to worry about replacing or repairing anything too significant.

One of the biggest draws of a sand filter is its ability to use the same filter media for many years. When you fill your filter tank with sand, you can use the same sand for a long time without noticing any negative results in your pool water. And when the time finally does come to change the media entirely, the process is usually pretty simple.

Sand filters are often used for mid-size to larger pools, but there’s no reason why you can’t use one on a smaller pool if you like. Just be sure to choose the right pump size and you’ll have no trouble with your new, strong sand filter.

Inground Pool DE Filter Systems

DE, or diatomaceous earth, is one of the more recent additions to the world of pool water filtration. This material comes from a type of algae that was fossilized a long time ago. These remains turn into a fine white powder when ground, and they have a lot of uses across the board. DE is often used in water filtration because it’s porous, which means the individual grains of earth can pick up contaminants and keep them from entering your water.

pump and filter combo

DE filters feature internal manifolds that are fitted with paper or fabric grids. The DE filter media is added to the tank of the filter system and is sloshed around until it sticks to these grids. As water passes through the DE, it is cleaned before it ever reaches your swimming pool.

Some people are concerned with using DE because it has been known to increase the risk of cancer when inhaled. However, if you take precautions such as wearing a mask when refilling and cleaning your filter, you should have no trouble using DE. If you prefer not to, you can find a few alternatives to this filter media.

Inground Pool Cartridge Filter Systems

Cartridge filters have been around for a long time, and they still remain a very popular choice for most pool owners. These are usually the most affordable types of filters on the market today, with a few exceptions, and they are often the easiest to set up and clean as well. They tend to be included with pop-up pools as well as with pool “kits” that can be purchased all at once. Sometimes, the filters included with these sets are not very strong.

inground pool cartridge filter systems

One of the downsides to using a cartridge filter system is the need to replace the cartridges inside pretty frequently. While DE can last a few years only needing a little bit added back to the filter every now and then, and sand can be used for five or more years with no trouble, cartridge filters usually need to be replaced every year. You can extend the life of your media by buying two and alternating them each time you clean your filter.

Since cartridge filters are popular, they’re very common, but it may be hard to find options that are strong enough for an inground pool. Be sure to stick with cartridge filters that are designated for use with inground pools, because they might not have enough power to handle the water otherwise.

Buying Pre-packaged vs. Buying Individual Filter System Pieces

Buying a pre-packaged filter set can be a great way to get your filter ready to go quickly, but there are some downsides to this choice, too. Check out our list of pros and cons to see if buying a filter system together is right for you, or if you might be better off purchasing the pieces individually and building your kit yourself.

Buying Pre-Packaged

  • You can save money by buying prepackaged. Usually, the companies that put these kits together give you a small discount when you buy the pieces all at once. If you look at the individual costs of the pieces you’d needed, you can see the difference in price pretty clearly in most situations.
  • You don’t have to worry about matching items together when you go this route. Especially when you’re new to swimming pools and their filter system, you may feel confused looking at all the different model numbers, strengths, and sizes of these products. By buying a filter kit all at once, you take away the guesswork of choosing the right products one at a time.
  • Buying prepackaged means all your products are under the same warranty. While you might think this is a strange thing to consider, think about what might happen if your whole system should break down at once. While this isn’t too common and it’s certainly an unfortunate consideration, it’s still something to keep in mind. With all your pieces under the same warranty, your whole system is protected and you won’t have to chase down a lot of different customer services if something should go wrong.
  • You can install everything at once when you choose a prepackaged set. When you bring everything home at once, it’s all contained in the same box. This makes installation a lot easier than it would be if you had to track down individual pieces you’d purchased over time. You’re also less likely to forget something you might need when you buy the whole kit together!

Buying Individually

  • Individual purchases allow you to customize your kit much more. For example, if you want a mid-size filter but prefer to use a more powerful pump that’s generally meant for larger pools, you can accomplish this by buying your pieces separately.
  • If you have existing pool equipment that will work with your new products, you can save money buying individually. Sometimes, the hoses and connections that come with a kit may require an adapter to function properly with your existing pool pipes. When you buy individually, you can pick and choose pieces that will work with the pipes you already have in place, so you don’t have to worry about getting adapter pieces.
