The 10 Best Pool Filters

Nothing ruins a hot summer day faster than a cloudy pool. I’ve been there. You think you’ve got the chemicals right, but the water just looks… sad. After years of trial and error with our 20,000-gallon inground pool, I can tell you the filter is the absolute heart of the whole system.

A good pool filter doesn’t just grab leaves and bugs. It catches the tiny, invisible stuff that makes water murky and gross. It’s the difference between a pool you can’t wait to jump into and a swamp you’d rather avoid.

So, I’ve put together a list of the best pool filters I’ve either used myself or have seen get amazing results for friends and neighbors in 2026. Whether you have a tiny above-ground splash pool or a huge inground oasis, there’s something here that will get the job done right.

 

 

D.E. Pool Filters (The Clearest Water)

Diatomaceous earth filters give you that sparkling, polished water look. They filter out the absolute smallest particles. The trade-off is they need a bit more attention than other types.

 

 

Hayward DE6020 ProGrid D.E. Pool Filter

The Hayward DE6020 is priced around $1,300. This is a serious filter for big inground pools.

If you want water so clear it looks like glass, this is your ticket. It handles a massive 120 gallons per minute, so it turns your water over fast. The filtration is just top-notch, grabbing stuff my old sand filter would miss. The body is made of some tough copolymer stuff that has held up great against the sun and rain.

The Downside: You have to add new D.E. powder every time you backwash, which can be a messy job. It’s more hands-on than a sand or cartridge filter for sure.

 

 

Hayward W3DE6020 ProGrid DE Pool Filter

This one comes in around $1,600. It’s another beast from Hayward’s ProGrid line, built for maximum clarity.

This filter gives you that incredible water clarity that only D.E. can provide. It’s got a big capacity and a flow rate of 120 GPM, so it’s perfect for larger inground pools that get a lot of use. The internal grid design really helps with the water flow and makes backwashing a little more effective.

The Downside: Just like any D.E. filter, it’s more work. You’re committing to regular backwashing and adding more powder to keep it running at its best.

 

 

Sand Pool Filters (The Workhorses)

I started with a sand filter and they are incredibly reliable. They’re simple, effective, and pretty low-maintenance. You just set it and forget it for weeks at a time.

 

 

Hayward W3S180T ProSeries Sand Filter

You can find this filter for about $500. It’s a classic for a reason and works on both inground and above-ground pools.

My neighbor has had one of these running for almost a decade without a single issue. It’s just a reliable workhorse. Backwashing is super easy—you just turn a handle. It’s built to resist corrosion and keeps a good, steady flow going to keep the pool clean.

The Downside: You do have to change out the sand every 3 to 5 years, which is a heavy, messy job. But it’s not something you have to think about often.

 

 

XtremePowerUS 19″ Swimming Pool Sand Filter

At around $270, this is a fantastic budget pick. It’s mainly for above-ground pools but can handle smaller inground ones too.

For the price, you get a really capable filter. It can handle pools up to 24,000 gallons, which covers a lot of backyard setups. The 7-way valve is great, giving you all the options you need for filtering, backwashing, rinsing, and more. It’s a simple, no-frills unit that just works.

The Downside: It’s designed mostly for above-ground pools, so it might feel a bit underpowered for a larger or deeper inground pool.

 

 

Intex Krystal Clear Sand Filter Pump

This whole pump and filter combo is a steal at $170. It’s the go-to for anyone with an Intex or similar above-ground pool.

We had one of these on our first little pop-up pool and it was a huge upgrade from the tiny cartridge filter it came with. The built-in timer is awesome for saving energy, and you only have to change the sand every five years or so. It’s the definition of low-maintenance for a smaller pool.

The Downside: It’s absolutely not meant for inground pools. It just doesn’t have the power or the right connections.

 

 

Intex 26651EG Krystal Clear Sand Filter Pump

For about $380, this is the bigger, more powerful version for large above-ground pools.

If you’ve got one of those huge, 19,000-gallon above-ground pools, you need more power, and this delivers. The 3,000 GPH motor really moves some water. It also has that handy auto-timer, making daily operation a breeze. It’s a solid, reliable choice for a big seasonal pool.

The Downside: It’s pretty heavy at nearly 50 pounds, so it’s a bit of a beast to move around and set up.

 

 

Carvin Laser 22.5-inch Sand Filter

This filter costs around $380. It’s designed for those massive above-ground pools that hold over 30,000 gallons.

This is a big filter for a big job. The 6-position valve makes it simple to backwash, rinse, and winterize. It has a good flow rate and is built to handle the water volume of a very large pool without struggling. It’s a great choice if you’ve got a huge backyard setup.

The Downside: It’s just the filter tank and valve, so you have to buy a pump separately. Make sure you get one that’s properly matched.

 

 

Cartridge Pool Filters (The Easiest Maintenance)

I love cartridge filters for their simplicity. There’s no backwashing—you just pull the cartridge out and hose it down. They filter better than sand but not quite as fine as D.E.

 

 

Pentair 160332 Clean and Clear Cartridge Pool Filter

This is a premium filter at $1,800. It’s for very large pools where you need huge capacity and flow.

This thing is an absolute monster. It’s designed for pools over 30,000 gallons and can keep up with heavy use. The best part is the maintenance. Instead of backwashing, you just open it up and rinse the cartridges with a garden hose. It provides really high, continuous flow to keep that big body of water circulating and clean.

The Downside: Those big cartridges don’t last forever. You’ll have to replace them every few years, and they aren’t cheap.

 

 

Bestway Flow Clear 1500 Pool Filter Pump

At only $150, this is a great starter pump and filter for small above-ground pools.

This is what you get for those smaller Bestway or Intex pools. It’s cheap, it’s easy to set up, and it moves enough water (1,500 GPH) to keep a small pool from turning into a pond. It’s a simple and effective solution if you’re on a tight budget.

The Downside: The small cartridges clog up fast, especially if you have a lot of leaves or pollen. You’ll be cleaning or changing them often.

 

 

Hayward SwimClear Pool Filter

This one costs about $880. It’s a fantastic mid-range option for medium-sized pools, both above-ground and inground.

This Hayward model hits a real sweet spot. The four-cartridge system provides a huge surface area, which means you don’t have to clean them as often as single-cartridge filters. It keeps the water really clean and maintenance is just a quick rinse with the hose a few times a season.

The Downside: A full set of replacement cartridges can be expensive when the time comes, so it’s a cost to keep in mind for the future.

 

 

How to Pick the Right Pool Filter

Choosing a filter really comes down to three things: your pool size, your budget, and how much work you want to do.

First, match the filter to your pool’s gallon capacity and your pump’s flow rate. A filter that’s too small will struggle to keep the water clean and will burn out your pump. Always go a little bigger than you think you need.

Then think about maintenance. D.E. gives you the best results but requires the most work. Sand is the old reliable, set-it-and-forget-it option. Cartridge filters are the easiest to clean but you have to buy new cartridges every few years. There’s no single “best” type, just the best type for you and your pool.
