Sure Purity is the exclusive provider of filters for Tomco's Beverage sector.

Sure Purity manufactures an advanced range of carbon dioxide multi-barrier polishing filters called carboguard.

carboguard polishing filters utilize molecular adsorption technology that polishes potential impurities from beverage grade Carbon Dioxide by creating a permanent bond between the impurity and the filter media. This is achieved by the adhesion of atoms, ions, or molecules from a gas, to the media surface. This process creates a film of the absorbate on the surface of the absorbent and can not be reversed.


  • Removes up to 10x more impurities than ISBT standards
  • Reduce maintenance downtime by more than 50%
  • 3rd party testing and validation
  • 58% reduction in consumables
  • Up to 50% OPEX savings & 28% CAPEX savings

Cartridge Design

A compact disposable cartridge design encapsulates the special filter media to ensure filter operation and handling is kept clean and hassle-free. Easy to install and maintain.

Multi-barrier Construction

Protection from multiple carbon dioxide impurities entering the beverage production process. One cartridge includes stages 2,3 and 4 of the 5 stage multi-barrier system.

Highly Selective Media

Three different high-performance filter media have been selected for their ability to target specific compounds.

High Level of Protection

Twelve months of continuous protection. Incident protection from inlet concentrations up to 10x ISBT guidelines for critical impurities such as aromatic hydrocarbon, H2S, COS, and more.


The carboguard mini was engineered to eliminate contaminants found in beverage-grade CO2 to protect retail restaurants, fast food chains, and other food outlets where beverages are dispensed at the point of sale.
