POOLPURE CCP420 Pool Filter Replaces Pentair Clean and Clear Plus 420 4Pack | Compatible with R173576, PCC105, 178584, Ultral-A6, Unicel C-7471, 817-0106, FC-1977, LxOD: 26"x7", 4X105 sq.ft. Cartridge

The POOLPURE CCP420 is widely recognized as the best swimming pool filter solution for owners of Pentair Clean and Clear Plus systems. This four-pack bundle offers a high-capacity filtration experience, ensuring that large pools remain clear by utilizing four individual 105 square foot cartridges for maximum debris capture.

Maintaining a pristine swimming environment requires reliable filtration, and this set is designed to replace factory originals with high-efficiency alternatives. By providing a full set of four, it allows for a complete system refresh rather than piecemeal replacements. The construction focuses on durability, utilizing materials intended to withstand the rigors of continuous water circulation. Prospective buyers should verify their specific system model number against the listed compatible units to ensure a proper seal and seating within the filter housing. This comprehensive approach to maintenance helps in sustaining water clarity over extended periods, making it a staple for those managing larger residential pool setups.

Practical fit

Ensuring a secure fit is the most critical step when installing these cartridges. While the product is marketed as a direct replacement for Pentair systems, users must confirm that their housing dimensions align precisely with the 26-inch by 7-inch specifications provided. A loose fit can lead to water bypassing the filtration media entirely, which reduces overall efficiency. Before purchasing, check your existing filter manifold to confirm it accommodates the four-cartridge configuration. Proper seating prevents internal leaks and ensures that the pump operates at the correct pressure, protecting the longevity of both the filter and the pool pump itself.

Tradeoffs and ownership

Owning a high-capacity filter system involves a balance between initial investment and long-term maintenance frequency. While these cartridges are designed for longevity, their effectiveness depends on the quality of the water and the frequency of the pump cycle. Owners should monitor pressure gauges closely; a significant rise in pressure typically indicates that the media has become saturated with debris and requires cleaning or replacement. Because this is a four-pack, the ownership experience is simplified by having a bulk supply ready, yet users must be prepared for the physical labor involved in deep-cleaning or rotating these large filter elements.

Best for: Large residential pools utilizing Pentair Clean and Clear Plus systems requiring a full cartridge refresh.

Buying guide

What to look for

Verify Model Compatibility

Before purchasing any replacement filter, carefully verify the model number of your existing pump housing. Listings often provide a list of compatible OEM part numbers or specific filter types, such as Type A or C. Do not rely solely on visual appearance, as cartridges can look identical while having different dimensions or thread types. Cross-reference the dimensions provided in the product listing with your current filter to ensure a proper seal. If you are unsure about compatibility, consult your original equipment owner's manual or contact the manufacturer's customer support. Installing an incompatible filter can lead to poor water filtration, potential damage to the pump motor, or leaks within the housing assembly, all of which can be costly to repair or replace.

Assess Filtration Capacity Needs

Consider the size of your pool and the frequency of its use when selecting a filter. Larger pools or those with high bather loads require filters with higher surface areas to effectively capture debris and keep water clear. Look for listings that specify the square footage or GPH rating to match your pump's power. If your current filter clogs too quickly, you may benefit from a high-capacity option. Conversely, for smaller, seasonal pools, a standard-sized cartridge is usually sufficient. Evaluate the balance between the initial cost of the filter and the expected lifespan. Investing in a high-capacity or premium-grade filter can sometimes reduce the frequency of maintenance, providing better overall value for your specific pool setup and usage patterns.

Understand Material Specifications

Filter cartridges are typically made from various materials, such as Dacron paper or reinforced synthetic fabrics. These materials differ in their ability to trap fine particles and withstand regular cleaning. Review the product description to understand the construction quality. Filters with reinforced cores or high-quality end caps generally offer better durability and are less likely to collapse under high water pressure. While basic paper filters are affordable, they may require more frequent replacement. Look for features like microbial resistance or high-density pleating if you are looking for enhanced filtration performance. Always prioritize materials that are specifically rated for pool use, as non-standard materials may degrade rapidly when exposed to pool chemicals or sunlight, leading to potential system failure or compromised water quality.

Check Included Accessory Packages

Some listings offer more than just the filter cartridge; they may include complete systems, O-rings, or cleaning tools. Determine whether you need a simple replacement or a broader equipment upgrade. If your current pump housing is showing signs of wear, a complete system replacement might be a more cost-effective long-term solution than continuously replacing cartridges in a failing unit. Always verify the contents of the package against your current needs. If a listing mentions complete accessories, ensure that these components are compatible with your existing plumbing. Buying a bundled kit can save time and effort, but only if every included part is actually required for your specific installation and maintenance needs.

Evaluate Manufacturer Reputation

When choosing between different brands, look for information regarding the manufacturer's consistency and quality control. While many aftermarket filters are designed to be compatible with major brands, the manufacturing standards can vary significantly. Read through buyer feedback to identify recurring themes regarding fit, longevity, and structural integrity. A reputable manufacturer will provide clear specifications and support for their products. Be wary of listings that lack detailed product information or have vague compatibility claims. Opting for a brand with a history of positive user experiences can provide peace of mind and help you avoid the frustration of receiving a product that does not meet expectations or fails prematurely during the swimming season.

Consider Long-Term Ownership Costs

The price of the filter is only one part of the ownership cost. Factor in the frequency of replacement and the potential for increased energy consumption if the pump has to work harder due to a restrictive or low-quality filter. High-quality filters that last longer may have a higher upfront cost but can be more economical over the course of an entire summer. Calculate your expected maintenance routine and the number of replacements you might need based on your local environment, such as heavy pollen or debris. By looking at the total cost of ownership rather than just the initial purchase price, you can make a more informed decision that aligns with your budget and maintenance goals.

Review Safety and Compliance

Ensure that any electrical equipment, such as pump systems, meets local safety standards and includes necessary features like GFCI protection. Safety should never be compromised for price. When purchasing filters or pumps, confirm that the product is designed for the intended application and complies with relevant safety regulations. If a product listing mentions safety certifications, take the time to verify what those certifications entail. Always follow the installation instructions provided by the manufacturer to ensure the equipment operates safely. If you have any doubts about the installation process or the electrical requirements of your pool equipment, consult with a licensed professional to ensure compliance with local codes and to prevent dangerous operating conditions.

Ownership guide

Setup, use, and maintenance

Routine Inspection and Cleaning

Regularly inspect your filter cartridges for signs of wear, such as fraying or structural collapse. To clean, remove the cartridge and rinse thoroughly with a garden hose to dislodge surface debris. Avoid using high-pressure sprayers, as these can damage the delicate filter media. If the cartridge remains discolored or clogged despite rinsing, it may be time for a replacement. Always follow the manufacturer's specific guidelines regarding cleaning frequency, as local water conditions, pool usage, and environmental factors will dictate how often you need to perform this task.

Monitoring Water Pressure

Keep a close watch on your pump's pressure gauge. A significant increase in pressure often indicates that the filter cartridge is becoming saturated with debris and requires immediate attention. Conversely, a sudden drop in pressure could signal a blockage or an issue with the pump intake. By tracking these readings, you can establish a baseline for your specific pool environment, allowing you to proactively manage your maintenance schedule. Always consult your owner's manual to understand the typical operating pressure range for your specific pump system.

Proper Chemical Balancing

Maintaining balanced pool chemistry is vital for extending the lifespan of your filter cartridges. High levels of calcium or improper pH can lead to scale buildup on the filter media, which significantly reduces its effectiveness and accelerates wear. Regularly test your water and adjust chemicals according to professional guidance and product labels. Never mix pool chemicals directly, and always add them to the water in the sequence recommended by your chemical supplier.

Safe Shutdown Procedures

Before performing any maintenance, inspection, or cartridge replacement, always turn off the power to your pool pump. Locate the electrical breaker or the pump's power switch and ensure it is fully disconnected. If your system includes a timer, ensure it is set to the off position. Never attempt to open the filter housing or handle internal components while the pump is energized, as this poses a significant risk of electrical shock or injury.

Seasonal Storage and Care

At the end of the swimming season, properly winterize your filtration system to prevent damage from freezing temperatures. Remove the filter cartridge, clean it thoroughly, and allow it to dry completely before storing it in a cool, dry place. If you are dismantling the pump housing, ensure all O-rings and gaskets are inspected for cracks or degradation. Lubricate seals with a silicone-based lubricant if recommended by the manufacturer. Store the pump and housing in a location protected from the elements.

FAQ

Pool Maintenance — FAQ

How often should I replace my pool filter cartridge?

The frequency of replacement depends on your pool's usage, local environment, and the specific filter type. Generally, cartridges should be replaced every few weeks to a few months. If you notice a persistent drop in water flow, a significant increase in pump pressure, or visible damage to the filter pleats, it is time for a new one. Regularly rinsing the cartridge can extend its life, but it will eventually lose its ability to capture fine particles. Always monitor your pump's performance and follow the manufacturer's recommendations for your specific model to maintain optimal water clarity and system health.

Can I use a different brand of filter than my pump manufacturer?

Yes, many aftermarket filters are designed to be compatible with major pool pump brands. However, you must ensure that the dimensions, thread type, and filtration specifications match your original equipment exactly. Always cross-reference the OEM part number with the replacement filter's specifications. Using an incorrectly sized or incompatible filter can cause leaks, poor filtration, or damage to your pump motor. When in doubt, consult your pump's owner's manual or contact the manufacturer to confirm compatibility before making a purchase. Quality aftermarket options can be just as effective as OEM parts if they meet the required specifications.

What should I do if my filter cartridge keeps collapsing?

A collapsing filter cartridge is often caused by excessive pressure within the system, which can be due to a clogged filter, a pump that is too powerful for the cartridge, or a blockage in the return lines. First, ensure the filter is clean and that there is no debris obstructing the water flow. If the problem persists, check your pump's pressure gauge to see if it is operating within the recommended range.

Is it safe to use pool chemicals to clean my filter?

You should only use cleaning agents that are explicitly recommended by the filter manufacturer. Many harsh chemicals can degrade the filter media, making it brittle or causing it to lose its ability to trap debris. Avoid mixing different chemicals, as this can be dangerous. A thorough rinse with a garden hose is often sufficient for routine maintenance. If a deeper clean is required, use a dedicated pool filter cleaner according to the product label instructions. Always prioritize safety, wear appropriate protective gear, and rinse the filter thoroughly before reinstalling it into your pool system to avoid introducing concentrated chemicals into the water.

How do I know if my filter is the right size for my pool?

The size of your filter is primarily determined by the flow rate of your pump and the volume of your pool. The manufacturer of your pool pump will specify the appropriate filter size or cartridge type required for the system. If you are unsure, check the label on your pump housing or refer to the original owner's manual. A filter that is too small will require frequent cleaning and may not provide adequate water turnover, while an oversized filter may be unnecessary. Ensure the filter's GPH rating is compatible with your pump's output to maintain a balanced and efficient filtration system.

Can I clean my filter cartridge with a pressure washer?

It is generally recommended to avoid using high-pressure washers on pool filter cartridges. The intense force of the water can tear the delicate filter media, damage the end caps, or flatten the pleats, all of which will permanently ruin the filter's ability to trap debris. A standard garden hose with a spray nozzle is the safest and most effective way to clean your cartridge.

What is the difference between Type A and Type C filters?

Type A and Type C filters are common designations for cartridge sizes used in many above-ground pool pumps, particularly those from brands like Intex. While they may look similar, they often have different dimensions or are intended for different pump flow rates. It is crucial to check your pump's manual or the label on your current filter to see which type is required. Using the wrong type can lead to a poor seal, allowing unfiltered water to bypass the cartridge, or it may not fit inside the housing at all. Always verify the specific type required for your pump model.

What does a high pump pressure gauge reading mean?

A high reading on your pump's pressure gauge typically indicates that the filter is clogged with debris and is restricting water flow. This increase in pressure forces the pump to work harder, which can lead to increased energy consumption and potential mechanical wear. When you see the pressure rise significantly above your system's normal operating range, it is time to clean or replace the filter cartridge.

Final verdict

Bottom Line

Choosing the right pool filter is essential for maintaining a clean and safe swimming environment. By focusing on compatibility, material quality, and the specific needs of your pump system, you can ensure efficient water circulation and long-term equipment health. Whether you select a high-capacity option for a large system or a budget-friendly replacement for a seasonal pool, prioritizing the correct fit is the most important step.

Regular maintenance and proactive monitoring of your filtration system will save you time and money in the long run. By following manufacturer guidelines, keeping your water chemistry balanced, and replacing cartridges before they fail, you protect your investment and enjoy clearer water. Always verify compatibility before purchasing and consult with a professional if you encounter issues, ensuring your pool remains a reliable source of summer enjoyment.
