An above ground pool skimmer is the single most effective weapon against the daily assault of leaves, bugs, grass clippings, and surface scum that turns clear water into a murky mess. A passive hanging basket just can’t keep up. The right thru-wall or mounted skimmer connects directly to your filter pump, creating constant surface suction that captures debris before it sinks—saving hours of manual scooping and keeping your chemical balance stable.

Whether you are upgrading an old cracked unit or installing the first skimmer on a new pool, the best above ground pool skimmer for your setup balances a wide mouth opening with a high-capacity basket and heavy-duty plastic that won’t warp after one season in the sun.
How To Choose The Best Above Ground Pool Skimmer
Picking the right skimmer is not just about matching the brand name on the box. Installation type, mouth width, basket depth, and plastic grade determine whether the unit works flawlessly or becomes a constant source of frustration. Focus on these three factors.
Installation Style: Thru-Wall vs. Wall-Mounted
Thru-wall skimmers require cutting a rectangular hole in the pool liner and sidewall. They are the permanent upgrade—better suction, larger basket capacity, and the professional look of an in-ground system. Wall-mounted skimmers like the Intex Deluxe clamp onto the top rail and connect to the pump via a hose. They are easier to install on soft-sided pools but offer less powerful suction and a smaller basket.
Material Quality and UV Resistance
ABS plastic is the baseline for durability. Heavy-duty grade ABS resists cracking when screws are tightened, does not warp under direct summer sun, and shrugs off chlorine and saltwater exposure. Thinner polypropylene units feel brittle right out of the box and often develop hairline cracks at the screw bosses during installation. Look for unibody construction and UV-stabilized resin blends.
Mouth Width and Basket Depth
The opening width determines how much surface area the skimmer covers. A wide mouth (7.5 inches or more) creates a stronger Venturi effect that pulls debris from a wider radius. Basket depth matters because a deeper basket holds more leaves before needing emptying—critical if you have trees overhanging the pool. Shallow baskets fill up in hours and reduce suction as they fill, making the pump work harder.

In‑Depth Reviews
1. JED Pool Tools Above Ground Pool Skimmer (45-400)
The JED 45-400 is the gold standard for a reason: it is manufactured in the USA by a family-owned company with over 35 years in the business, and the ABS plastic feels substantially denser than the competition. The internal opening measures 5-7/8 inches wide by 8-5/8 inches long—a generous footprint that pulls debris from a wide radius around the cutout. Owners consistently report that the basket is large enough to hold a 3-inch chlorine tablet without blocking flow, a rare dual-use feature that simplifies chemical distribution.
Installation requires care because the U-gasket needs perfect alignment to prevent leaks, but the included instruction sheet is clear enough for a DIY afternoon. Many users pair this with a skimmer sock to catch fine particles before they reach the pump, and the square-mouth design works with Intex, Bestway, and Coleman filter systems without adapters. The vacuum plate attachment is a thin plastic piece—functional but not the highlight of an otherwise premium kit.
Water quality improvement is immediate. Owners of 14-foot and 18-foot above ground pools report that the skimmer eliminates the daily surface film and cuts manual vacuuming frequency in half. The weir door floats correctly right out of the box, maintaining consistent suction even as the water level fluctuates. For a long-term upgrade that you install once and forget about, this is the unit every other skimmer gets compared to.
What works
- Dense, crack-resistant ABS that outlasts cheaper plastics
- Large basket can double as a chlorine tablet holder
- Compatible with most major filter pump brands
- Clear, beginner-friendly installation instructions
What doesn’t
- Thin vacuum plate attachment feels fragile
- Gasket requires careful alignment to avoid slow leaks
- Weir float can fail if the foam insert gets waterlogged
2. Rx Clear Heavy Duty Wide-Mouth Thru-Wall Skimmer Kit
The Rx Clear kit stands out because of its extra-deep debris basket—the inner opening stretches 11-1/2 inches long, making it the longest basket in this lineup. That translates directly to fewer trips to empty the basket during peak leaf season. The unibody ABS construction is UV-stabilized and chemical-resistant, so the white housing does not yellow or become brittle after multiple summers of chlorine exposure and direct sun.
What makes this kit genuinely complete is the inclusion of two full sealing gaskets, a directional eyeball return fitting, and a skim vacuum plate. The adjustable eyeball lets you direct the return water flow to create a circular current that pushes surface debris toward the skimmer—a simple trick that dramatically improves efficiency. The weir flapper door snaps into place securely and responds to even light water movement.
One area where the Rx Clear stumbles slightly is the instruction sheet. Owners frequently note that the manual does not show the order of assembly clearly, requiring a quick YouTube search to confirm which gasket goes on which side of the pool wall. Once installed correctly, the seal is watertight, and the suction is strong enough to pull floating leaves from ten feet away. This is a set-it-and-forget-it upgrade for owners who want the deepest basket on the market.
What works
- Deepest basket reduces emptying frequency
- Includes adjustable directional eyeball for circulation
- UV and chemical resistant unibody material
- Two full gaskets for leak protection
What doesn’t
- Installation diagram is missing critical assembly steps
- Outer dimensions may be tight on some pool wall cutouts
- Vacuum plate lacks a 90-degree elbow fitting
3. Swimline Hydrotools Standard Wide Mouth Skimmer (8939G)
The Swimline Hydrotools Wide Mouth Skimmer delivers the best Venturi-effect suction in this price tier. The wide rectangular opening creates a low-pressure zone that draws debris in aggressively, reducing the amount of manual vacuuming needed. Owners report that surface bugs and pollen are captured before they have a chance to dissolve into the water, which makes a noticeable difference in chemical demand. The snap-in and removable weir simplifies winterization—pop it out and store it indoors.
Assembly is the one area where this skimmer demands patience. The included self-threading screws require significant force to bite into the ABS plastic; many experienced installers recommend pre-drilling pilot holes to prevent stripping. The paper template included in the box is roughly 3/4-inch too small, with misaligned hole positions, so measuring the cutout directly against the housing is safer. Once mounted, the seal holds tight without silicone as long as the screws are fully seated.
The basket itself is a point of minor frustration—owners describe it as serviceable but slightly brittle, more prone to cracking if accidentally stepped on or dropped on concrete during cleaning. The kit includes a vacuum adapter with a 90-degree elbow, return fitting, and Teflon tape, which adds real value. For pool owners who prioritize surface skimming power above all else and are comfortable with a finicky installation, this unit outperforms its price class.
What works
- Excellent Venturi suction draws debris from a wide radius
- Snap-in weir removes easily for winter storage
- Comes with vacuum adapter and adjustable eyeball
- No silicone needed for a leak-free seal when installed correctly
What doesn’t
- Basket plastic feels thin and brittle
- Paper template is undersized and misaligned
- Self-threading screws can strip without pre-drilling
4. TonGass Universal Fit Above Ground Pool Skimmer Kit
The TonGass kit is the most complete package in the mid-range category. It includes the skimmer body, cover, weir, face plate, face plate cover, basket, gasket, vacuum plate, hose fitting adapter, return fitting, and 12 stainless steel screws—everything needed for a full thru-wall installation right out of the box. The ABS construction is sturdy enough that owners report zero deformation after a full year of installation, even in pools exposed to full afternoon sun.
The opening width measures 6 inches by 7-1/2 inches, making it compatible with most standard pool wall cutouts. Owners with 18-foot above ground pools note that the skimmer catches an impressive amount of debris, particularly bugs and small leaves that older narrower skimmers missed. The included gasket is adequate but thin; several experienced users recommend applying a bead of silicone caulk around the inner edge during installation to guarantee a leak-proof seal from day one.
Quality control is the main variable with this unit. A small percentage of customers receive units with a broken weir flap or cracked basket, likely from rough shipping handling. The instructions are confusing, but the assembly is intuitive enough that most owners complete the job in under 30 minutes using common sense. For the bundle of components included, this stands as the strongest value proposition for a first-time thru-wall installation.
What works
- Most complete accessory bundle in the price range
- Sturdy ABS stays flat and doesn’t warp in heat
- Universal fit works with standard pool cutouts
- Good debris capture on medium-sized leaves and bugs
What doesn’t
- Weir flap can arrive broken due to poor packaging
- Gasket is thin; extra caulk recommended for leak-free install
- Instructions are poorly written and hard to follow
5. Kefly Above Ground Pool Skimmer with Accessories
The Kefly skimmer is the most recent entrant on this list, and it earns its spot through a combination of a generous 2-year product protection plan and a thoughtful design that prioritizes easy cleaning. The basket can be accessed from both the top and the front, which is a genuine convenience when the skimmer is installed in a tight corner where the lid is hard to reach. The weir and gasket fit snugly out of the box, and the stainless steel screws resist corrosion better than the zinc-plated alternatives found on cheaper kits.
Installation is straightforward for anyone who has done a pool skimmer before, but first-timers should pay close attention to one recurring feedback point: the screw holes are not pre-drilled. Multiple owners report that attempting to drive the screws directly into the plastic causes the heads to strip or the screws to bind halfway, leading to leaks. Pre-drilling with a 1/8-inch bit solves the problem completely, and the skimmer then seats perfectly against the pool wall with no gaps.
Debris capture performance is solid for a mid-range unit. Owners with three or more trees surrounding the pool report that weekly basket emptying keeps the surface clear all season. The included faceplate cover snaps on firmly and does not pop off during heavy rain. The hose fitting adaptor included is standard size, but owners wishing to use non-standard hose diameters may need to purchase a separate adapter. For the price, the 2-year warranty is a standout advantage that reduces the risk of buying online.
What works
- Top and front basket access for tight installations
- 2-year product protection plan provides peace of mind
- Stainless steel screws resist rust better than coated alternatives
- Snap-on faceplate cover stays secure in wind
What doesn’t
- Screw holes not pre-drilled; must pre-drill to avoid stripping
- Gasket alone may not seal; extra caulk recommended
- No adapter for non-standard hose diameters
6. Intex Deluxe Wall Mounted Auto Skimmer (58949E)
The Intex Deluxe Wall Mount is the go-to option for Easy Set and soft-sided pool owners who cannot cut a hole in the pool wall. It clamps to the top rail and connects to the filter pump via the included hose and adapter, creating automatic surface skimming without any permanent modification. The adjustable bracket fits both round and oval metal frame pools, and the polypropylene plastic construction is chemically inert, so it does not degrade from chlorine contact.
The critical requirement here is pump flow. The skimmer needs a minimum of 800 GPH from the connected filter pump to generate adequate suction; owners running smaller 500 GPH pumps will find the skimmer ineffective, with debris floating past the intake. Upgrading to a 1000 GPH or higher pump dramatically improves capture rates. The strainer basket pulls out for cleaning, though the basket capacity is noticeably smaller than a full thru-wall unit, requiring more frequent emptying near trees.
The bracket mounting system is the weak point on earlier versions, but Intex addressed this with sturdier plastic clamps on the current 58949E model. Owners praise the quick setup—most complete installation in under 15 minutes without tools. The trade-off is that the skimmer sits on the pool edge and can be knocked loose by kids splashing or strong winds. It works best as a supplemental skimmer on a pool that already has a basic filter setup, not as a primary solution for heavy debris loads.
What works
- No wall cutting required; clamps to the top rail
- Quick 15-minute installation without tools
- Works with Intex pumps at 800 GPH and above
- Updated model has sturdier clamps than older versions
What doesn’t
- Ineffective with pumps under 800 GPH
- Small basket fills quickly in heavy debris conditions
- Can be dislodged by splashing or strong wind
7. Funsicle SkimmerPlus 2-in-1 Filter Pump and Skimmer (P53FX1500)
The Funsicle SkimmerPlus takes a different approach—it is a 2-in-1 unit that combines a 1500 GPH filter pump with an integrated skimmer in a single housing. This eliminates the need for a separate skimmer and separate pump, reducing clutter around the pool and simplifying the plumbing. The ultra-fine filter paper cartridge captures particles that a standalone skimmer basket would let through, resulting in noticeably clearer water between chemical treatments.
Installation is the fastest of any unit on this list because there is no separate skimmer to align and seal. The unit attaches directly to the pool’s outlet and inlet openings, and the included 1.5-inch hose and clamps complete the setup in under 15 minutes. Owners report that the water circulation is excellent—the return flow creates a gentle current that sweeps debris toward the integrated skimmer intake, creating a self-reinforcing cleaning loop.
The most significant limitation is the built-in timer that Funsicle added to recent production units. The timer runs for 1 to 10 hours and then shuts off, with no manual override option. For owners who run a pool heater, this automatic shutoff can interrupt water flow and risk overheating the heater. The unit is also the most expensive option here, but for small pools (10 to 15 feet) where space and simplicity matter more than raw skimmer capacity, this all-in-one solution delivers convenience that a separate skimmer cannot match.
What works
- All-in-one design saves space and simplifies plumbing
- 1500 GPH flow rate provides strong circulation
- Ultra-fine filter cartridge produces clearer water
- Quick 15-minute installation with no separate skimmer mounting
What doesn’t
- Built-in timer cannot be overridden; shuts off automatically
- Not suitable for pools paired with a heater
- Highest upfront cost among the reviewed options
Hardware & Specs Guide
ABS vs. Polypropylene Plastic
ABS plastic is the superior material for above ground pool skimmers because of its impact resistance, UV stability, and chemical tolerance. Polypropylene is lighter and cheaper but tends to develop stress cracks at screw points over time. The difference in durometer hardness means ABS housings hold screws tighter without stripping, and unibody ABS skimmers are less likely to leak at the seams after thermal expansion and contraction cycles.
Mouth Width and the Venturi Effect
Skimmer mouth width directly affects the pressure differential that pulls debris across the surface. A standard opening of 6 inches creates moderate suction, while a wide mouth measuring 7.5 inches or more generates a stronger Venturi effect that accelerates water velocity at the opening. This pulls floating debris from a wider radius and reduces the time it takes to clear the entire pool surface after a wind event or mowing session.
