SPECIAL FILTER®

Compact multi-technology filtration for taste improvement, sediment reduction and scale prevention

Compact Water Filtration

Better-tasting water and scale protection / In one quick-change cartridge

SPECIAL FILTER® is a compact cartridge platform combining activated-carbon filtration with FILTERSORB® SP3 scale-prevention media. The SP 520UF model adds an ultrafiltration membrane.

The activated-carbon block supports the reduction of chlorine, unwanted taste, odor and sediment, while FILTERSORB® SP3 helps reduce the formation of hard scale without adding sodium or phosphate. The SP 520UF incorporates a nominal 0.1-micron ultrafiltration stage for additional fine-particle and microbiological control when operated within validated conditions. The quick-change head includes automatic water shut-off for faster, cleaner cartridge replacement.

Carbon filtration / Scale prevention / Optional ultrafiltration

SPECIAL FILTER Introduction

Compact filtration.
For drinking water and food-service equipment.

SPECIAL FILTER® cartridges are designed for cold-water, point-of-use installations where improved taste, sediment reduction and scale protection are required.

Drinking-Water Dispensers

Compact filtration for improved taste, odor and clarity at the point of use.

Coffee and Espresso Machines

Scale protection and chlorine reduction for beverage equipment and coffee preparation.

Restaurants and Cafés

Treated water for beverage preparation and compatible catering equipment.

Ice Makers and Refrigerators

Filtration for connected cold-water appliances and ice-production systems.

Vending Machines

Compact cartridge treatment for water-fed beverage-vending equipment.

Dishwashers and Steam Equipment

Scale-management support for compatible appliances operating within temperature and flow limits.

Four filtration capabilities across one compact product family

CP

Activated-Carbon Block Filtration (CARBON-PURE™)

The carbon-block stage supports chlorine, taste, odor, sediment and selected adsorbable-organic reduction when supported by appropriate performance testing.

SG

Salt-Free Scale Prevention (SCALE-GUARD SP3™)

FILTERSORB® SP3 supports nucleation-assisted crystallization, helping convert dissolved temporary-hardness minerals into microscopic crystals with a reduced tendency to attach to equipment surfaces.

UF

Nominal 0.1-Micron Ultrafiltration (UF-BARRIER™)

Available in the SP 520UF model, the ultrafiltration membrane provides an additional barrier for fine particles and microorganisms larger than the validated membrane cutoff.

QL

Fast Cartridge Exchange (QUICK-LOCK™)

The insert-turn-lock cartridge connection and automatic water shut-off simplify cartridge replacement without regeneration, electricity or a separate brine system.

Science & Technology

SPECIAL FILTER® combines different physical treatment mechanisms. Each technology performs a distinct function and should be described separately rather than applying every removal claim to every model.

  • Carbon Adsorption – Activated carbon provides a large internal surface on which chlorine-reaction products and adsorbable organic compounds can be retained or reduced.
  • Mechanical Filtration – The carbon-block structure intercepts sediment and suspended particles larger than its published nominal filtration rating.
  • Nucleation-Assisted Crystallization – FILTERSORB® SP3 promotes crystallization of dissolved calcium carbonate into microscopic crystals while retaining calcium and magnesium in the water.
  • Ultrafiltration Barrier – The SP 520UF adds a nominal 0.1-micron membrane (microbiological claims require an absolute pore rating, integrity controls and organism-specific log-reduction testing).

Frequently
Asked Questions

Essential information about SPECIAL FILTER® models, treatment technologies, capacities and cartridge replacement.

Contact Support
What is SPECIAL FILTER®?
It is a compact quick-change filter family combining activated-carbon filtration and FILTERSORB® SP3 scale prevention. SP 520UF adds an ultrafiltration membrane.
What is the difference between SP 510 and SP 520?
Both use carbon-block and scale-prevention technologies. SP 520 is taller and provides a higher published flow and capacity than SP 510.
What additional treatment does SP 520UF provide?
It adds a nominal 0.1-micron ultrafiltration membrane for additional fine-particle and microbiological control.
Does SPECIAL FILTER® soften water?
No. FILTERSORB® SP3 does not remove calcium and magnesium like an ion-exchange softener. It changes the crystallization behavior of temporary hardness to help reduce scale attachment.
Does it add sodium or phosphate?
The brochure states that the scale-prevention stage operates without adding sodium or polyphosphate.
Can the filter remove existing scale?
It is intended primarily to reduce new scale attachment. Do not claim rapid removal of existing deposits without application-specific evidence.
Does it reduce chlorine, taste and odor?
The activated-carbon block is intended to support chlorine, taste and odor reduction. Certified capacity depends on influent concentration and flow.
Does SP 520UF remove bacteria and viruses?
A nominal 0.1-micron UF membrane may physically retain many bacteria. Virus removal should not be claimed without certified log-reduction testing because many viruses are smaller than 0.1 micron.
How long does a cartridge last?
Cartridge life depends on water quality and consumption. Replace it when capacity is reached, after the specified time limit or when performance declines—whichever occurs first.
Does the system require electricity or regeneration?
The cartridge itself requires no electrical supply, brine regeneration or chemical dosing. It must still be replaced periodically.
What is the maximum operating temperature?
The brochure lists a maximum of approximately 37.8°C. The product should be used only on cold-water lines unless a current data sheet states otherwise.
Is it suitable for lead-contaminated water?
Do not rely on the product for lead reduction without a current product-specific certification showing capacity, flow, influent concentration and breakthrough performance for the exact cartridge model.
