Picking a filter for an above-ground or in-ground setup gets old fast. Tank size, plumbing, flow rate, and media type all matter, and the wrong match means cloudy water and a pump working harder than it should. This list walks through nine solid new pool filter systems across cartridges, sand, and DE so you can match the right setup to your pool, your plumbing, and the amount of maintenance you actually want to deal with.

The Picks, Examined More Closely
If your pool already runs on a Pentair Sta-Rite System 2 or PLM series tank, replacing a tired cartridge with the IMOLI 27002-0150S gets you back to clean water without a full system swap. The cartridge slots right into the existing housing, so weekend upkeep stays simple. For most backyard pools in the mid-size range, the 150-square-foot media area keeps turnover steady through busy swim seasons.
The build leans toward longevity: a reinforced center and a chemical-tolerant end cap help the cartridge hold up to repeated rinse cycles. Compared with the Palmetto sand refill coming up next, this is a different kind of maintenance, more of a swap-and-go part than a media top-off, and it suits anyone who already knows the Sta-Rite form factor.
What Makes Sense
- Direct-fit replacement for Pentair Sta-Rite System 2 and PLM150 tanks, no plumbing changes required.
- 150-square-foot media surface handles typical residential turnover without straining the pump.
- Trilobal fabric structure captures fine debris like hair, sand, and sunscreen residue.
- Reinforced end cap resists chlorine wear, helping the cartridge last across multiple seasons.
- Simple rinse-and-reuse cleaning, no backwash valve or extra plumbing to manage.
Trade Offs
- Not a universal fit, so owners of other filter brands will need a different cartridge.
- Periodic deep cleaning is still required once surface debris builds up between swaps.
Best Suited To
Sta-Rite System 2 or PLM150 owners who want a drop-in cartridge that matches original dimensions and keeps maintenance predictable.
Look Elsewhere When
The Hayward ProSeries 18-Inch Sand Filter suits you better when you want a full sand system for an above-ground pool rather than a replacement cartridge for an existing tank.
Palmetto’s #20 grade silica sand is the kind of consumable that quietly disappears in the background, and a 10-pack of 50-pound bags covers years of sand-filter top-offs for most households. The #20 (20-40 mesh) grade is the standard size most residential sand filters expect, so it drops into popular tanks without adjustment. Anyone running a sand system on an above-ground pool will eventually need a refill, and this bundle covers that chore in one delivery.
Pre-washed and screened media means less dust cloud when you pour it in, and the uniform grain size helps the filter bed pack evenly for balanced backwashing. Pair it with the Hayward ProSeries 18-Inch Sand Filter a few picks down, and you have a complete above-ground setup ready for a season of swim days.
What Works In Its Favor
- 10 bags of 50-pound #20 silica sand, enough for multiple filter refills over the years.
- Pre-washed and screened to reduce dust and grit at startup.
- Standard 20-40 mesh that fits most residential sand filter tanks.
- Bulk format lowers the per-pound cost compared with single-bag purchases.
Things To Consider
- 500 pounds of sand is heavy, so plan for help unloading and a dry storage spot.
- Only suits sand filter owners, owners of cartridge or DE systems will not use this media.
- Sand eventually channels and needs full replacement every few seasons.

Reach For A Different Pick When
The AQUASTRONG 14in Sand Filter Pump fits better when you need a full pump-and-tank package for a small above-ground pool rather than media alone.
The Pentair CLN/CLR 100 Center Core is the kind of part you only think about when something goes wrong, but it matters a lot. It is the central support structure inside Clean & Clear and Clean & Clear Predator 100-square-foot cartridges, and a cracked or warped core means the filter can no longer hold proper pleat spacing. Replacing the core restores the original geometry and gets the cartridge filtering like new again.
For owners of those Pentair tanks, the CLN/CLR 100 core is an OEM-spec repair part, so fit is exact and installation follows the standard cartridge teardown. This is repair territory rather than upgrade territory, and it pays off when the rest of the cartridge is still in decent shape but the core has tired out.
Where It Helps
- OEM Pentair part designed for Clean & Clear and Clean & Clear Predator 100 sq ft filters.
- Restores the central support that holds the pleated media in shape.
- Extends the life of an existing cartridge instead of forcing a full replacement.
Honest Caveats
- Only useful if the rest of the cartridge is still serviceable, otherwise the fix is incomplete.
- Niche fit, Pentair Clean & Clear 100 owners are the only audience.

Swap It Out When
The Pentair 27002-0100S Sta-Rite D.E. Filter Module is a better pick when you run a Sta-Rite PLM100 system instead of a Clean & Clear cartridge tank.
Hayward’s ProSeries 18-inch top-mount sand filter is a familiar sight on above-ground pools, and for good reason. The 18-inch tank holds enough media to keep small to mid-size pools turning over, while the top-mount design keeps valve access within easy reach for backwashing. The internal laterals are built to spread water evenly across the sand bed, which helps the filter run cleaner between backwashes.
Compared with the cartridge picks earlier in this list, sand filtration is more about the system than the cartridge. You load the tank with media, set the valve, and let physics do the rest. The trade-off shows up in fine-particle capture: a cartridge will pull smaller bits out of the water, while sand leaves a little more for the pool chemistry to handle.
Notable Upsides
- Top-mount valve keeps connections and controls accessible from ground level.
- Even-flow lateral system supports balanced backwashing and long media life.
- Works with above-ground pools, on-ground pools, small in-ground pools, and even ponds.
- Compatible with standard #20 silica sand, easy to source for refills.
Points To Note
- Backwashing uses pool water, so plan for drainage and occasional water-top-off.
- Sand media needs replacement every few seasons as the bed channels and packs down.

A Better Fit Elsewhere
The AQUASTRONG 18in Sand Filter Pump is worth a look when you want the filter and pump bundled together with a built-in timer.
The Pentair 27002-0100S is the OEM replacement module for Sta-Rite PLM and System 2 modular media filters in the PLM100 configuration. At 100 square feet of filtration area, it handles the work for mid-size residential pools running through a Sta-Rite tank. When an old module starts to collapse or lose pleat integrity, this swap keeps the system filtering like the day it was installed.
For shoppers familiar with the IMOLI 27002-0150S cartridge earlier in this list, the difference comes down to size: that cartridge covers the 150-square-foot PLM150, while this one matches the 100-square-foot PLM100. Both use the same modular Sta-Rite design language, so installation follows the same teardown steps.
Useful Touches
- OEM Pentair module designed specifically for PLM100 and System 2 tanks.
- 100-square-foot media area matches the original spec, so flow behavior stays consistent.
- Standard 13-5/8-inch diameter and 18-3/8-inch height align with existing Sta-Rite housings.
- Modular design means each module can be replaced individually rather than swapping the whole system.
A Few Limitations
- Only fits Sta-Rite PLM and System 2 tanks, no use in other brands.
- Spent DE media (if used) needs proper disposal after backwash cycles.

Skip It When
The XtremepowerUS 60 Sq. Ft. DE Pool Filter is a stronger match when you need a complete in-ground DE system rather than a Sta-Rite module.
The AQUASTRONG 18-inch sand filter pump packages the tank and motor together, so you do not have to match components across brands. The 1.5 HP motor moves water at up to 8100 GPH, which is enough turnover for pools around 28,000 gallons when sized correctly. The built-in 6-way valve and programmable timer take the daily chore out of running the system.
For above-ground pool owners stepping up from a basic filter setup, the combination approach is convenient. Compared with the smaller AQUASTRONG 14-inch model further down the list, this one trades compact size for stronger flow and a larger sand capacity, which fits longer plumbing runs and higher-demand pools.
The Value In It
- All-in-one pump and tank package simplifies installation and parts matching.
- Programmable timer with 9 cycle settings (2 to 24 hours) automates daily filtration.
- 6-way valve supports backwash, rinse, filter, waste, closed, and recirculate modes.
- 1.5 HP motor delivers 8100 GPH flow for pools up to around 28,000 gallons.
Things To Weigh
- Heavier than tank-only sand filters, so a level pad and stable base matter.
- Sand media is a separate purchase and not included with the unit.
Key Product Details
Perfect Match For
Above-ground pool owners with mid-size pools who want a combined pump-and-tank system with a built-in timer.
Not Your Match When
The AQUASTRONG 20in Sand Filter Pump fits larger pools closer to 38,000 gallons and brings more flow headroom.
The 14-inch AQUASTRONG sits at the compact end of the lineup, sized for smaller above-ground pools up to around 13,000 gallons. The 2/3 HP motor and 3000 GPH flow rate match the kind of gentle circulation a small pool needs without overpowering the plumbing. A 6-way valve and 9-setting programmable timer bring the same convenience as the larger sibling models.
Where the 18-inch and 20-inch AQUASTRONG pumps lean toward turnover volume, this one leans toward efficiency and footprint. It is easier to tuck beside a small deck, and the lighter current suits setups where the pump sits close to the pool wall.
A Strong Showing
- Compact 14-inch tank fits tight pad areas beside small above-ground pools.
- 6-way valve handles backwash, rinse, filter, waste, closed, and recirculate.
- Programmable timer with 9 cycle settings for hands-off daily operation.
- Lower 2/3 HP draw keeps energy use modest for smaller water volumes.
Practical Considerations
- Flow rate tops out around 3000 GPH, so larger pools will outgrow it quickly.
- Smaller sand bed means more frequent backwashing in heavy-use weeks.
Who Will Love This
Owners of small above-ground pools who want a space-saving pump-and-tank combo with the same programmable controls as the larger AQUASTRONG models.
Where A Sibling Pick Shines
The AQUASTRONG 18in Sand Filter Pump is the smarter upgrade for pools pushing toward the upper teens in thousands of gallons, where 3000 GPH starts to feel thin.
The 20-inch AQUASTRONG tops the family’s above-ground sand filter lineup, with a 2 HP motor pushing up to 8917 GPH through a larger sand bed. It is built for pools approaching 38,000 gallons, and the higher flow rate keeps the water turning over even when multiple swimmers are in the pool at once. The same 6-way valve and 9-setting timer found on the smaller models carries over.
Compared with the 14-inch model earlier, the jump from 3000 GPH to nearly 9000 GPH is dramatic, and the larger tank holds more sand for longer intervals between backwashes. The honest read is that this size fits people who regularly host a crowd or run a busy swim-season schedule.
Strong Points
- 2 HP motor and 8917 GPH flow rate cover pools up to around 38,000 gallons.
- 20-inch tank holds more sand, reducing backwash frequency during heavy use.
- 6-way multiport valve supports the full range of standard service modes.
- 9-setting programmable timer (2 to 24 hours) automates daily cycles.
Points To Keep In Mind
- Larger motor draws more power than smaller AQUASTRONG models.
- Bigger footprint requires a sturdy level pad and a bit more clearance space.
Key Attributes
Right Fit For
Big above-ground pool owners and busy swim households who need the turnover headroom and longer sand cycles a large tank provides.
Where Another Pick Suits Better
The XtremepowerUS 60 Sq. Ft. DE Pool Filter earns its place when you have an in-ground pool that needs finer DE filtration rather than a sand pump.
DE filtration, where diatomaceous earth coats internal grids to trap very fine particles, is the in-ground pool’s friend when water clarity is the priority. The XtremepowerUS 60-square-foot DE filter runs on a 120 GPM flow rate through a reinforced tank, and the 2-inch inlet and outlet match standard residential plumbing. A pressure gauge and air relief valve sit at the top of the unit for quick checks during routine maintenance.
For shoppers weighing sand against DE, the trade-off is straightforward. Sand systems like the Hayward ProSeries 18-inch model are simpler to live with, while DE pulls noticeably finer particles from the water at the cost of periodic media recharging. The XtremepowerUS sits firmly in the in-ground DE camp.
The Case For It
- 60-square-foot DE media area captures fine particles that sand and cartridge setups often miss.
- 120 GPM flow rate supports in-ground pools and spas with 2-inch plumbing.
- Built-in pressure gauge and air relief valve simplify routine checks.
- Reinforced tank construction handles the higher operating pressures of DE systems.
Where It Is Less Suited
- DE powder requires handling and proper disposal at recharge and backwash.
- More involved maintenance than a basic sand filter, especially for first-time DE owners.
Technical Reference
Who Should Grab It
In-ground pool and spa owners who want the fine-particle capture of DE media and a complete tank with built-in monitoring gauges.
Consider Something Else When
The Pentair 27002-0100S Sta-Rite D.E. Filter Module suits a Sta-Rite PLM100 owner better when the goal is a replacement module rather than a whole new DE system.
What Matters Most When Choosing new pool filter systems
Pool size sets the foundation. Match filter media area and pump flow rate to the gallons of water in the pool, since undersized systems churn through chemistry and oversized ones waste energy. Cartridges like the IMOLI 27002-0150S suit mid-size residential pools, while sand systems in the AQUASTRONG lineup cover anything from a small 13,000-gallon setup up to a 38,000-gallon above-ground giant.
Media type changes the daily experience. Cartridges are swapped and rinsed, sand is backwashed, and DE is recharged with powder. The right pick depends on how much hands-on maintenance you want, and whether you have a convenient spot to drain backwash water.
Plumbing compatibility is a quiet dealbreaker. Above-ground pumps need hoses and fittings that match the pool wall ports, and in-ground DE systems like the XtremepowerUS assume 2-inch plumbing. Skipping the fit check up front turns an upgrade into a parts hunt.
Key Considerations Across These Picks
Wrong Turns To Avoid
The most common slip is buying by tank size alone and ignoring flow rate. A small filter on a big pool runs nonstop and never quite catches up, while an oversized pump on a tiny pool burns through media without giving you cleaner water. Match flow rate, media area, and pool gallons together rather than chasing one number.
Another trap is treating filter media as a one-time purchase. Sand lasts a few seasons before it channels, cartridges need rinsing and eventual replacement, and DE powder runs out with every backwash. Plan for the consumable, not just the unit.
When Paying More Pays Off
The jump from a basic sand setup to a programmable pump-and-tank combo like the AQUASTRONG 18-inch or 20-inch buys you automation and stronger flow. The timer alone pays back in daily convenience, and the larger motor keeps the pool clearer during high-bather-load weekends.
Spending more on DE filtration, like the XtremepowerUS 60 sq ft system, buys finer particle capture. For in-ground pools where water clarity is a point of pride, the extra maintenance trade is often worth it.
Frequently Asked Questions
How often should pool filter media be replaced?
Sand typically needs replacement every three to five seasons once it starts to channel, while cartridges are rinsed regularly and replaced when pleats wear out. DE powder is recharged after each backwash, and the grids themselves last for years with proper care.
Can a sand filter handle the same pool size as a DE system?
Sand filters can cover similar pool volumes, though they capture larger particles and leave finer work to the pool’s chemistry. DE systems like the XtremepowerUS 60 sq ft filter pull smaller debris out of the water, which is why many in-ground owners prefer them despite the extra media handling.
What does a 6-way valve actually do?
A 6-way valve is the multiport control on top of many sand and DE filters. It switches between filter, backwash, rinse, waste, closed, and recirculate modes, so you can reverse flow to clean the bed, send water to waste, or isolate the tank during service.
Are aftermarket cartridges as good as OEM?
Aftermarket cartridges like the IMOLI 27002-0150S are designed to match OEM dimensions and often use reinforced end caps and trilobal media for longer life. Fit and flow behavior match the original, though material quality can vary by brand, so check dimensions and compatibility before swapping.
Do above-ground pumps need a dedicated circuit?
Most above-ground pool pumps run on standard 115V outlets, but a dedicated circuit prevents tripped breakers when the pump shares a line with other backyard loads. A GFCI-protected outlet near the pad is the typical setup.
Closing Remarks
The right filter comes down to your pool size, your plumbing, and how much maintenance fits your routine. Cartridge replacements like the IMOLI and Pentair modules keep existing tanks running, the AQUASTRONG pumps bundle tank and motor for new above-ground setups, and the XtremepowerUS DE unit covers in-ground pools that want finer filtration. Pick the one that matches your pool today rather than overbuying headroom you may never use.
