Swimming Pool Filter Media:
What Type Do You Need?

When you’re looking for the best swimming pool filter sand sale items, you might feel a little overwhelmed by all the alternatives out there. Below, you’ll be able to explore a few sand filter media options as well as several DE filter media options to help you find the best fit for your pool setup.

pool filter media options

Sand Filter Media PROS & CONS

Below are three of the most common pool sand filter media choices: pool sand, filter glass, and ZeoSand. Each of these products has its own strengths and weaknesses that you’ll need to consider before choosing the one that’s best suited to your pool’s specific needs.

Pool Sand

Pool sand has long been used as a great way to provide clean, filtered water for swimming pools as well as other water-based recreation. This is the most common type of media you might find for use in a sand filter, but you don’t have to be limited to it if you prefer to work with something different. Pool sand is readily available, but it might not offer the amount of filtration you need in your pool.


  • Very easy to find at any pool supply or home repair store, and very affordable as well.
  • Easy to use since sand filters are designed with this product in mind.


  • Often washes into the pool water, making it cloudy and gritty.
  • May need to be replaced much more frequently than other types of sand filter replacements.

Filter Glass

Although you might be surprised to hear it, filter glass really is made of glass! It’s usually made from recycled glass materials that are repurposed into swimming pool filtration alternatives. You can use it in much the same way you would use sand in your filter, but you generally won’t need nearly as much of it. In fact, the ability to cut back on the amount of this filter media needed is one of the biggest selling points for this particular product.


  • Great for the environment and a wonderful choice for anyone who wants to live an eco-friendly lifestyle.
  • Great at clearing up the water much more quickly than other types of filtration.


  • More expensive and harder to find than traditional pool sand.
  • May not be compatible with all types of filters or pumps.


ZeoSand is a natural product that works on the principle of ion exchange to filter your pool water perfectly every time. It’s made of zeolite, which is a great replacement for sand because of its similar texture and grain. This product has recently become very popular among swimming pool owners, and more and more pool techs and installation crews are recommending it for use in sand filters to extend the life of the filter as well as the pool.


  • Capable of getting rid of ammonia in your swimming pool water, which some other filter media types can’t do.
  • Even better at filtration overall than traditional sand filter media.


  • This is a much more expensive product than pool filter sand, and may not fit into everyone’s budget.
  • This product may not work well with all types of pool filters, so you’ll need to be sure yours is compatible.

DE Filter Media PROS & CONS

If you prefer to use earth for pool filter products or opt for an earth-like alternative, these great options can help you find the right fit for your pool. Choose between diatomaceous earth, cellulose fiber, and perlite to make your pool clean, clear, and safe for swimming all season long. Be sure to pay special attention to all the advantages and disadvantages of each of these products so you can be sure the one you choose is going to work for your setup.

Diatomaceous Earth

Diatomaceous earth is the most common material found in DE filters. This is the type of filter media these filters are designed for, and it works in a fairly simple manner. All you have to do is fill the filter basket with the right amount of media, turn it on, and let the laterals push the media around until they’re coated for perfect filtration.


  • DE is readily available from any pool supply store and is fairly inexpensive compared to other alternatives.
  • It’s very easy to purchase bulk quantities of DE and store them carefully until they’re needed.


  • Exposure to diatomaceous earth can cause irritation of the skin, eyes, nose, and throat, and if you breathe it in, you may notice shortness of breath or severe coughing.
  • Some people believe that diatomaceous earth can contribute to the risk of cancer, although there haven’t been any major scientific studies to prove this.

Cellulose Fiber

Cellulose fiber is both non-toxic and biodegradable, which makes it a very popular choice for swimming pool owners. It provides clean, clear water without having to resort to harsh chemicals or substances you’d rather not be exposed to.


  • This is a very green product that’s safe for the environment as well as for swimmers with sensitive skin.
  • You don’t need to use as much cellulose fiber in your filter as you do with traditional DE.


  • This can be a very pricey product that may be well over the budget of some pool owners.
  • Since this product isn’t as popular as other alternatives to DE, it may be more difficult to find.


Perlite is similar to silica in its look, feeling, and creation. This is a common product used in gardening, but in recent years, it’s become more and more popular in pool filters as well. Although perlite might not be for everyone, it definitely does have its place among swimming pool filter media.


  • This is a very lightweight product that moves through your filter efficiently.
  • You don’t need to use as much perlite as you do DE in your filter.


  • Backwashing may cause you to lose a lot of perlite every time.
  • In extremely rare circumstances, this product can contribute to silicosis, a lung disease that can also be caused by pool sand.


Now that you’ve seen just how many excellent types of pool filter media you have to choose from for your sand and DE filters, it’s time to pick your favorite! Choosing the right type of replacement sand for pool filter use or DE alternative doesn’t have to be a difficult process. Just pick the one that seems like it would work best with the way you use your pool, and be sure to choose something that fits your personal preferences, such as eco-friendly alternatives.

But how do you know when it’s time to change your filter media in the first place? Do you know if you need to be thinking about this already, or does your media have a lot of life left in it? Follow these simple tips to determine when it’s time to change your filter:

  • Change your filter if your water is visibly dirty.
  • Change your filter if your water feels gritty or slimy.
  • Change your filter if you hear your pump making strange lurching or gurgling noises.
  • Change your filter if you can look inside and see the media blocking the laterals or building up too much during operation.

When you know it’s time, one of these excellent pool filter media options will help you make the most of your swimming pool by offering you clean, clear, safe water all season long.
