PoolPure PCC105-PAK4 4-Pack Cartridge Filter (replaces Pentair Clean and Clear Plus 420)

What it is and why people buy it

PoolPure PCC105-PAK4 is a 4-pack of replacement cartridge filters for certain pool filter setups. It’s designed as a compatible spare part intended to replace cartridge models referenced in the listing (including Pentair Clean and Clear Plus 420 / CCP420 references and multiple cross-part numbers).

On paper, the pitch is straightforward: restore filtration performance without upgrading your whole system. For pool owners who want their water to look “cleaner and clearer” between cleanings, cartridge replacements like this are usually the fastest path—swap the media, rinse, and get back to regular circulation.

That said, it’s not perfect for everyone. If your current cartridge is a different size or uses a different connection/top opening setup, this pack may not be a drop-in fit. Compatibility depends heavily on matching the cartridge’s dimensions and your specific filter model.

The essentials (key specs you can actually use)

You’re looking at a cartridge with:

• Length: 26"
• Outside diameter (OD): 7"
• Top opening: 3"
• Bottom opening: 3"
• Filter material/area: 105 sq.ft
• Filter material: trilobal filtration fabric

Those numbers matter because cartridge filters are unforgiving: even when a listing claims compatibility across several brands, the physical fit and opening sizes are what determine whether you can install it and whether water flows through the media the way it should.

Where it stands out in day-to-day filtration

This filter is built around trilobal filtration fabric. The listing claims the trilobal fiber structure offers more adsorption surface area than conventional filter fabrics, and that it helps capture more dirt and sediment while maintaining consistent clarity—even with frequent use.

There’s also a “dirt-locking” approach intended to capture debris and make rinsing easier. In practical terms, you’re buying into a maintenance experience: rinse off trapped debris, reuse the cartridge, and spend less time scrubbing or cycling through replacements more often.

If you’re the kind of pool owner who’s tired of the filter looking “done” too quickly after a few weeks of heavy use, this is the type of cartridge that aims to hold up better during normal seasons of pollen, dust, and everyday debris.

Key tech notes you should care about

Two claims in the listing are worth highlighting because they speak to peace of mind and industry alignment:

• NSF/ANSI 50 safety certification (via IAPMO) for material safety in pool/spa water exposure.
• Membership in the Pool & Hot Tub Alliance (PHTA), positioning it around industry-recognized filtration standards.

If you’re prioritizing safety and want more than generic “replacement media” reassurance, these details help justify the purchase.

One more thing: the listing also mentions testing/recognition elements (including a reference to an Olympic swimmer and media mentions). Those are supportive brand signals, but they’re not the same as independent testing for your specific pool setup. Consider them as marketing context, not proof that every pool issue will disappear.

Compatibility: how to avoid the common mistake

This is explicitly described as a compatible spare part, and the manufacturer names/part numbers are used for reference. That’s helpful, but it also means you should verify fit before ordering.

It’s listed as compatible with certain models/part references such as Pentair CCP420 and various cross numbers (the listing includes items like 160301, Waterway Crystal Water 425, and several others). Still, the safest way to confirm is to match the cartridge dimensions and your filter’s top/bottom opening requirements.

It may not be a great match if: - Your existing cartridge doesn’t align with the 26" length and 7" outside diameter. - Your system requires a different top/bottom opening setup. - You’re expecting a universal fit across all “420-like” filters without checking measurements.

Pros, cons, and who it fits best

Strengths

• 4-pack format can lower the hassle of frequent reorders during the swim season.
• Trilobal filtration fabric and dirt-locking design are aimed at better debris capture and easier rinsing.
• NSF/ANSI 50 material safety certification claim is a meaningful reassurance.

Limitations to keep in mind

• It’s positioned as compatible, not OEM, so the “replaces” relationship depends on your specific cartridge fit.
• The listing doesn’t provide micron rating or pressure guidance, so you won’t know exactly how it performs versus other media types without checking your flow conditions.

Who it’s for

It makes sense if you own a compatible pool filtration system and you want a replacement cartridge bundle that’s built around debris capture, easier maintenance, and safety claims.

It might not suit you if you’re running a system with strict OEM-specific fit requirements, or if you haven’t confirmed that your current cartridge matches the listed dimensions.

Getting the most from your cartridge

Even the best media won’t perform if it’s neglected. After installing a new cartridge, do a quick baseline rinse/inspection during your next maintenance cycle. If you notice flow slowing or the cartridge getting unusually dirty faster than expected, don’t just keep running—check your water chemistry and filtration schedule.

A small “micro” example: if your pool tends to pick up pollen after windy days, swapping in this cartridge batch and then giving it a proper rinse at the next maintenance window can help you stay clearer between cleanings rather than letting debris build up until performance noticeably drops.

Final verdict

If you need a compatible replacement cartridge filter and you can confirm your setup matches the listed dimensions and openings, the PoolPure PCC105-PAK4 4-pack is a practical way to keep filtration consistent without overcomplicating your equipment.

It’s not the best buy if you want guaranteed drop-in OEM fit with zero checking, or if your cartridge size differs from 26" length and 7" outside diameter. For most buyers doing a straightforward swap based on fit, it’s a solid “maintenance-first” replacement with safety and filtration-media claims you can lean on.

Quick FAQ

Is this an original Pentair part?

What size cartridge is it?

The listing provides length and diameter details (26" length and 7" outside diameter) plus 3" top and 3" bottom openings.

What filtration media does it use?

It uses trilobal filtration fabric, with a stated goal of higher adsorption surface area.

How many cartridges come in the pack?

It’s a 4-pack.
