105 sqft 7" Diameter Filter Cartridge
Product Overview
The standard specification for pool techs maintaining Pentair Clean & Clear Plus 420 filtration systems.
This Filbur 105 sqft cartridge is a proven choice for homeowners running the Pentair Clean & Clear Plus 420sq ft filter. In our experience, these cartridges reliably handle high flow rates while maintaining the tight tolerances required to prevent debris bypass. Each element features 105 square feet of high-quality media, designed to be swapped into the housing as a set of four to ensure peak water clarity and system efficiency.
Benefits & What Makes It Different
105 Square Feet of Media
Provides ample surface area to trap fine particulates and organic debris, ensuring water clarity even during heavy bather loads.
Precise 7-Inch Diameter Fit
This specific diameter ensures a snug fit within the internal manifold of the Pentair housing, which is critical for preventing unfiltered water bypass.
Reinforced End Caps
The durable end cap construction resists cracking under high pressure, maintaining the structural integrity of the pleats throughout the season.
Compatibility
- Pentair Clean & Clear Plus 420 Filter Housing
- Systems requiring 7-inch diameter by 26-inch length cartridges
- Filbur FC-1977 equivalent specifications
When To Use This
Pro Tip
When cleaning these, avoid using a high-pressure power washer; a standard garden hose with a spray nozzle preserves the life of the fibers and prevents premature tearing.
Common Questions & Instructions
How many 105 sqft cartridges do I need for a Pentair Clean & Clear Plus 420?
You need exactly four of these 105 sqft cartridges to fill the Pentair Clean & Clear Plus 420 filter housing, totaling the required 420 square feet of filtration area.
How do I know if my filter cartridge needs to be replaced right now?
You should swap out the cartridge if you see a persistent rise in tank pressure that cleaning no longer resolves, or if you notice visible tears in the pleats or crushed center cores.
Can I replace just one cartridge in my 420 sq ft filter?
While possible, pool techs reach for a full set of four because mixing old, clogged cartridges with one new one creates uneven flow and puts excessive stress on the new element.
