Atlas Filtri 20 Inch BIG SX Clear Refillable

Atlas Filtri 20 Inch BIG SX Clear Refillable

The Atlas Filtri P 20 BIG SX Clear Refillable Cartridge is an empty, heavy-duty filter container designed for large-capacity water treatment. Made in Italy, this eco-friendly option allows you to choose your own bulk filter media and refill the cartridge manually, significantly reducing single-use plastic waste.

Here is everything you need to know about its specifications, capabilities, and compatibility:

Specifications

• Height: 20 inches

• Outer Diameter (OD): 4.5 inches (Jumbo / Big Blue size)

• Configuration: SX model featuring a standard DOE (Double Open End) configuration with a flat antimicrobial gasket to prevent bacterial growth.

• Material: Perfectly transparent, durable PET body with a polypropylene end cap and internal grid.

• Temperature Range: 4°C to 45°C (39.2°F to 113°F)

• Safety: Fully compliant and certified safe for use with drinking (potable) water.

Key Benefits & Features

• Modular Versatility: The 20-inch version is uniquely designed to allow modularity. It features internal grids and felt pads that let you split the chamber into two halves, meaning you can pack two different types of loose media into a single cartridge without them mixing.

• Full Visibility: The crystal-clear transparent body makes it incredibly easy to inspect the condition, color, and depletion level of your filter media at a glance.

• Cost-Effective & Sustainable: Instead of throwing away an entire plastic cartridge when the media becomes saturated, you simply unscrew the cap, dump the old media, rinse, and refill it with bulk material.

Recommended Media Types

You can fill the P 20 BIG SX with a wide range of loose media depending on your filtration goal:

• Granular Activated Carbon (GAC): For removing chlorine, volatile organic compounds (VOCs), bad tastes, and odors.

• Polyphosphate Crystals: For preventing limescale formation, scale buildup, and pipe corrosion.

• Anion/Cation Exchange Resins: For water softening (calcium/magnesium removal) or demineralization.

• Calcite: For neutralizing acidic water and raising pH levels.

Compatibility

This cartridge is specifically engineered to fit perfectly into the Atlas Filtri DP BIG 20" housings, but its universal 20" x 4.5" dimension means it is also highly compatible with most standard 20-inch "Big Blue" or Jumbo filter housings on the market.
