Here’s an overview of the Best Pool Filter that we’ll explore today:
Pool filtration is the heartbeat of a clean, inviting swimming environment. A high-quality cartridge filter can dramatically improve water clarity, reduce chemical demand, and extend between maintenance cycles. This review evaluates five cartridge filters across a broad price spectrum—from budget-friendly replacements to premium, high-capacity cartridges. My methodology combines specification analysis, real-world compatibility considerations, and a practical assessment of ease of maintenance, durability, and performance. Where possible, I compare each product against common pool sizes, pump configurations, and backwashing limitations that influence long-term value.
1. POOLPURE PLF120A Pool Filter Replaces Hayward C1200
- Brand: POOLPURE
- Manufacturer: POOLPURE
The PLF120A from POOLPURE is a compatible, 120 square-foot cartridge designed to slot into a wide range of Hayward, Unicel, and Filbur bodies. It leverages trilobal filtration fabric and a 50-micron refinement layer, paired with dirt-locking technology for easier rinsing. At $69.99, it sits firmly in the mid-budget tier and emphasizes durability with 4 oz. thickened fabric and reinforced end caps. The NSF/ANSI 50 certification adds credibility for material safety in residential pools, and the 120 sq.ft. filtration area balances flow resistance with effective debris capture.
In practice, the PLF120A delivers solid performance for typical residential pools using standard 1.5 to 2 HP pumps. The 50-micron layer helps with fine particles, though you should expect more frequent rinsing if your pool sees heavy debris or finer sediments. Its dirt-locking design can reduce maintenance time, but note that it is not intended for backwashing, which makes it best suited for non-backwash filtration systems or those with compatible rinse cycles. The 23 1/4″ length and 8 15/16″ OD are compatible with many common cartridge housings, but always verify exact model compatibility before purchase.
Pros
- Broad compatibility with popular Hayward/Unicel/Filbur housings
- 50-micron filtration with trilobal fabric for better particle capture
- Dirt-locking technology simplifies cleaning
- NSF/ANSI 50 certified material safety
- Relatively affordable for 120 sq.ft capacity
Cons
- Not designed for backwashing systems
- Performance depends on pump sizing and flow; may require more frequent rinsing in dusty areas
2. Intex 29002E Type A Pool Filter Cartridge Filter Pumps – Easy-to-Clean – Dacron Paper – Efficient Filtration – Two Pack
- Brand: Intex
- Manufacturer: Intex
Intex’s 29002E Type A is a two-pack cartridge designed for Intex Krystal Clear filter pumps, leveraging easy-to-clean Dacron paper media and Hydro Aeration Technology to improve circulation and clarity in above-ground pools. Priced at a budget-friendly $6.99, it targets cost-conscious consumers who replace cartridges bi-weekly for optimal results. The specification highlights compatibility with specific Intex pump models (28603EG, 28637EG, 28635EG) and emphasizes HydroAERATION as a design differentiator that can enhance turnover and perceived water freshness.
From a performance standpoint, this cartridge is best suited for smaller, above-ground pools with Intex-pump configurations. The Dacron-based media is easy to replace and replace regularly, but it does not offer the heavy-duty filtration depth of premium pleated media. For users who prioritize low upfront cost and straightforward maintenance, the 29002E provides a predictable, fuss-free replacement cycle; however, it is less forgiving in pools with heavy leaf load or fine sediments, where more robust filtration may be warranted.
Pros
- Very low upfront cost
- Easy-to-clean Dacron media facilitates quick replacement
- HydroAeration Technology can improve circulation
- Compatible with common Intex pump models
- Two-pack provides value for routine replacements
Cons
- Limited filtration depth versus pleated cartridges
- Compatibility restricted to specific Intex pumps
- No specifics on micron rating in product data
3. POOLPURE PCC105-PAK4 Replaces Pentair CCP420
- Brand: POOLPURE
- Manufacturer: POOLPURE
The PCC105-PAK4 from POOLPURE is a high-capacity 105 sq.ft cartridge intended as a replacement for several premium brands and patterns, including Pentair CCP420 and Ultratech-style units. At $179.99 for a 4-pack, it targets buyers seeking long replacement intervals and compatibility across a broad ecosystem of filter bodies. The trilobal filtration fabric and 50-micron layer are carried forward, with dirt-locking technology designed to simplify rinsing. The shorter 26″ length and 7″ OD position this cartridge as a mid-length option for larger-capacity housings.
Performance-wise, the PCC105-PAK4 is well-suited for mid-to-large residential pools with decent turnover rates, especially when paired with a pump that can sustain adequate flow through a 105 sq.ft cartridge. Durability improvements are claimed due to the same thickened fabric and reinforced end caps, which can help extend life in calcified environments. The kit form (4-pack) offers strong value for multi-season maintenance, but the upfront cost is higher, so confirm your housing compatibility and any potential warranty considerations with POOLPURE’s customer support before buying.
Pros
- High-capacity 105 sq.ft per cartridge
- Wide compatibility with major brands/models
- 4-pack provides extended maintenance interval and better unit pricing
- 50-micron filtration and trilobal fabric for effective debris capture
- NSF/ANSI 50 certified materials
Cons
- Higher upfront cost
- Not all installations will benefit from 105 sq.ft if flow is limited by pump
- Not designed for backwashing
4. POOLPURE PLF175A Pool Filter Replaces Hayward C1750
- Brand: POOLPURE
- Manufacturer: POOLPURE
The PLF175A is POOLPURE’s 175 sq.ft cartridge, a high-capacity option that aligns with large residential or pool/spa combinations. At $79.99, it sits at a mid-to-upper mid-range price point given its substantial filtration area. The design continues to leverage trilobal filtration fabric and dirt-locking technology, with a 50-micron filtration layer and reinforced end caps intended to extend service life. The 28 3/16″ length and 8 15/16″ OD make it a fit for many larger canister-style housings.
In practice, the PLF175A shines in pools that demand longer run cycles and stronger debris handling, such as homes with big gatherings or landscapes that shed a lot of leaves. The increased surface area reduces pressure spikes and can improve overall water clarity when paired with properly sized pumps. Cleaning remains straightforward due to the dirt-locking mechanism, though users should still schedule regular monthly maintenance in areas with high particulate matter. The price-to-capacity ratio is favorable for its class.
Pros
- Large 175 sq.ft filtration area for bigger pools
- Strong value for a high-capacity cartridge at sub-$100
- 50-micron trilobal fabric with dirt-locking technology
- Broad compatibility with multiple major brands
- Durable construction with reinforced end caps
Cons
- Not ideal for very small pools where 175 sq.ft would be excessive
- Not designed for backwashing
- May require careful measurement to ensure housing compatibility
5. HYDROTOOLS Cartridge Pool Filter Tanks
- Brand: Swimline
- Manufacturer: Swimline
Swimline’s Hydrotools 40 SF Cartridge Filter Tank is a complete cartridge-filter-tank combination designed for both above-ground and inground pools, providing a 40 square-foot filtration area and a tank-based system. Priced at $164.99, it targets users who want a self-contained filter tank with a clear gauge and a self-contained housing, rather than a simple cartridge. The system supports pumps from 1/3 to 1.5 HP and is marketed as a durable, UV-resistant, heavy-duty option. Notably, this product is a filter tank that pairs with the included elements and gauge, but it does not include a pump base or plumbing fittings, which affects total installed cost.
In terms of performance, the Quad-Cell distribution and oversized tank capacity can extend filter cycles, particularly in pools up to 21,000 gallons. The inclusion of a pressure gauge and release valve helps monitor head pressure over time, aiding maintenance. However, the absence of a pump and plumbings means you must select compatible components separately, which adds planning steps and potential compatibility questions. For many homeowners, this is a more architectural choice—prioritizing a robust tank with easily replaceable cartridges over a compact, all-in-one unit.
Pros
- Integrated filter tank with cartridge elements
- Quad-cell distribution supports even debris capture
- Pressure gauge and bleed valve aid maintenance
- Durable UV-resistant construction
- Suitable for large pools up to ~21,000 gallons
Cons
- Does not include pump base or plumbing fittings
- Higher upfront cost relative to standalone cartridges
- Compatibility requires matching tank and cartridge specifications
