Future Way CCP420 Pool Filter Cartridges Replacement for Pentair Clean & Clear Plus 420, Replace Pentair R173576, Pleatco PCC105-PAK4, 420 sq.ft, 4-Pack
🏆 Best For: Best for Compatibility
When it comes to pool filter compatibility, the Future Way CCP420 stands out as the "Best for Compatibility" for 2026. This cartridge is engineered to fit a wide range of models, including the Pentair Clean & Clear Plus 420, Pleatco PCC105-PAK4, and others using the R173576 part number. As a seasoned pool pro, I’ve seen how inconsistent filter brands can lead to leaks, poor performance, and costly repairs. The CCP420’s universal fit and consistent flow rate of 420 sq.ft. ensure that your system runs smoothly without the need for custom fittings or adapters.
Real-world benefits include long-lasting performance and minimal maintenance. The pleated media is designed to trap fine particles, reducing the frequency of backwashing and chemical usage. With a 4-pack, you’re set for seasonal use and can plan your filter replacement schedule without last-minute trips to the store. The durable construction also means fewer replacements over time, which saves both money and hassle. For a homeowner who wants to keep their pool running efficiently without constant adjustments, this is a reliable choice.
This filter is ideal for pool owners with existing Pentair or Pleatco systems, especially those looking to streamline their maintenance routine. It’s perfect for Memorial Day setups where you want your pool ready for guests without the stress of compatibility issues. If you’re replacing an old filter or upgrading from a lower-quality model, the CCP420 is a smart investment that aligns with both practicality and chemistry-aware maintenance.
One caveat to consider is that while it’s compatible with many models, it’s not a universal fit for all systems. You’ll still need to verify the exact model number and part compatibility before purchasing. Additionally, while it’s durable, it may not offer the same level of filtration efficiency as some high-end specialty filters, which could mean slightly more frequent backwashing in heavy-use scenarios.

Swimara CCP420 PCC105 178584 R173576 817-0106, 5 oz+ Trilobal Fabric Pool Filter Cartridges, Compatible with Pentair Clean & Clear Plus 420 (#160301) & Waterway 425, 4-Pack, Ultra Series
🏆 Best For: Best for Durability
The Swimara CCP420 PCC105 178584 R173576 817-0106 earns the “Best for Durability” title due to its high-density trilobal fabric construction, which resists clogging and maintains flow efficiency over time. Unlike standard filter media, this design minimizes the need for frequent backwashing and chemical adjustments, making it ideal for maintaining consistent water clarity. The 5 oz+ weight per cartridge ensures it can handle heavy debris loads without compromising performance, which is crucial for pools with high bather traffic or in areas with high pollen or dust levels.
Each cartridge is compatible with several popular filter models, including Pentair Clean & Clear Plus 420 and Waterway 425, offering a versatile solution for pool owners who may have multiple systems or are upgrading. The 4-pack provides a cost-effective way to stock up, reducing downtime during filter changes. The material’s resistance to chemical degradation also means less frequent replacements, saving both time and money in the long run. This is a filter that truly stands the test of time, especially in environments where water chemistry can be challenging to balance.
This filter is best suited for pool owners who prioritize long-term reliability over frequent maintenance. It’s ideal for those with older systems that are still performing well but require more durable media, or for those who want to reduce the frequency of filter replacements. It’s especially recommended for use during peak swimming seasons, such as Memorial Day, when water usage and chemical demand are at their highest. Pool professionals and DIYers alike will appreciate the peace of mind it provides.
One caveat is that the trilobal fabric may not be as effective at trapping very fine particles compared to diatomaceous earth (DE) filters, though it’s still highly efficient for most residential applications. Additionally, while the 4-pack is economical, the initial cost per cartridge is higher than some alternatives, which may be a consideration for budget-conscious buyers.
✅ Pros

- Reduces backwashing frequency
- Compatible with multiple filter models
❌ Cons
- Less effective on fine particles
- Higher per-unit cost
- Key Feature: Resists clogging

One potential drawback is that the pack doesn’t include installation tools or detailed guides, which might be a hurdle for less experienced users.

Factors to Consider
Frequently Asked Questions
How often should I backwash my sand filter?
Backwash your sand filter every 4–6 weeks or when the pressure gauge rises by 8–10 psi. This helps remove trapped debris and maintains optimal filtration efficiency. Over-backwashing can waste water and energy, while under-backwashing can lead to clogged filters and poor water clarity.
Can I use a cartridge filter for a large pool?
Cartridge filters are generally better suited for smaller to mid-sized pools. They can handle up to 30,000–50,000 gallons of water effectively. For larger pools, a sand or DE filter is more efficient and requires less frequent maintenance. However, some high-quality cartridge filters can be used in larger pools with proper sizing and regular cleaning.
Do DE filters require more chemicals than sand filters?
No, DE filters don't require more chemicals. In fact, they can reduce chemical usage by up to 20% because their finer filtration means less strain on the pool's sanitizer. However, DE filters need regular maintenance to prevent buildup, which can affect water balance if not addressed.
What's the average lifespan of a sand filter?
A well-maintained sand filter can last 10–15 years. Regular backwashing and proper chemical balance are key to extending its life. Neglecting maintenance can reduce its lifespan by up to 50%, leading to more frequent replacements and higher costs over time.
Are there any filters that are better for energy efficiency?
High-efficiency filters with energy-saving motors are the best for reducing electricity costs. These filters often use variable-speed pumps, which can cut energy use by up to 50% compared to traditional models. Look for filters with a high CFM rating and energy-efficient certifications for long-term savings.
Can I use a filter from a different brand with my pump?
Compatibility depends on the filter's flow rate and the pump's specifications. Always check the pump's maximum flow rate and ensure the filter's capacity matches or is slightly less. Using a mismatched filter can cause strain on the pump and reduce the filter's efficiency, leading to higher maintenance costs.
Conclusion
Choosing the right pool filter is essential for maintaining clear water, efficient chemical balance, and long-term equipment health. Based on the research and practical insights, the DE filter stands out for its superior filtration and ease of maintenance when paired with a high-efficiency pump. For everyday use and Memorial Day enjoyment, investing in a reliable, energy-efficient filter will save you time, money, and headaches in the long run.
