6 Best Sand Filters Reviewed for 2023



A filter is to your pool as a liver is to the human body. It’s the handy little contraption that removes all the bad stuff from your pool (just like your liver does for your body) to keep your pool healthy and clean. 

Swimming in your backyard pool is the dream. Therefore, dirty, stagnant, or algae-ridden water is not an option. If you’re struggling to decide on a pool filter or need a replacement for a busted one, a sand filter might be your best bet.

What is a Sand Pool Filter?

A sand pool filter is a simple and easy-to-maintain filtration system for your pool. It works by filtering your pool water through layers of sand before circulating it back into your pool, all sparkly and clean.

The sand in a sand pool filter is no ordinary sand, however. The most common sand used in sand filters is silica sand, a specially-graded form that actually absorbs impurities and traps contaminants that wash through it during filtration.

These types of filters have remained extremely popular among pool owners due to their low-maintenance design. The only real upkeep a sand pool filter needs is the occasional backwash and sand replacement, meaning you probably only need to open the tank once every few years.

One of the benefits of a sand pool filter is that as it continues to do its job, it actually gets more efficient. The more dirt and contaminants that the sand filter collects from the pool water, the more dirt it will trap as time goes on. It’s pretty amazing.

What Types of Sand Pool Filter Can You Buy?

The two main types of sand filter pumps are designed for either in-ground or above-ground pools, although some can work with either type of pool.

It’s important to read the specifications very carefully for whatever filter you’re looking at to make sure it’s compatible with your pool. 

What to Consider When Buying a Sand Pool Filter

If you’re looking into getting a sand filter for your pool, whether as a first time purchase or as a replacement for an existing filter, there are some important factors you’ll want to consider.

It can be a bit tricky trying to navigate all of the options out there but not to worry, we’ve got you covered. Let’s take a look at the big ones you should think about when making your decision.

The Size of Your Pool

How many gallons of water does your pool hold? This is the first question to ask when looking to get a new pool filter. 

A general rule of thumb is that you need one (1) square inch of filter area for every 1,000 gallons of water in your pool. So, if your pool has 20,000 gallons of water, you’ll need a 20-inch tank. Take a peek at the manufacturer’s guidelines for your pool in case you’re unsure. 

Pro Tip: If you’re looking to improve your filter pump efficiency, it might be a good idea to get the next size up from what your manufacturer recommends.

Gallons Per Hour (GPH)

You’ve probably heard that it’s a good idea to run your pool pump anywhere from 10-12 hours per day for maximum pool cleaning productivity. Before settling on a new sand filter, you should decide how many hours you plan to run your pump in a day. 

Now let’s do some quick and easy math. Take the total volume of water in your pool and divide it by the number of hours you plan to run the pump. The number you end up with is the filter you need (i.e. one that is able to move that many gallons per hour).

Total Water (Gallons) / # of Hours Pool Pump Runs (Per Day) = GPH

Note: Some sand filter pumps give their specifications in gallons per hour and some in gallons per minute. Read carefully!

What’s Your Climate Like?

If you own a pool and live in a place that freezes in the winter, you already know the wear and tear that Jack Frost can cause. It may be worth noting that there are some sand filter pumps out there that are easy to uninstall and drain for winter storage in your garage or shed.

If you live in a cold climate where the temperatures routinely drop below freezing, it may be a good idea to pick up one of these models to significantly increase the lifespan of your system.


Sand filters are the best bang for your buck when it comes to pool filter pumps. The initial cost, combined with low maintenance costs over years of use, makes them a great value to keep your pool clean for years to come.

The only maintenance cost generally associated with sand filters is the replacement of sand every 5-7 years or so.

A sand filter pump is going to be the least expensive option out there when it comes to filtering your pool. The other filter pump options are more costly, so you’ve already found the best budget-friendly option. 

We’ve compiled our favorite sand pool filter pumps for in-ground pools, above-ground pools, and some that work with both. Now, it’s up to you to decide what will work best for your pool, your lifestyle, and your budget.
