NO Compromise on quality - equipped exclusively with Pentair Water filters (USA)

  • Comprehensive Filtration: The combination of these filters provides a thorough filtration process, addressing a wide range of contaminants.
  • Healthier Water: By removing sediments, chlorine, heavy metals, chemical contaminants, and bacteria, the system ensures healthier drinking water for your household.
  • Improved Taste and Odor: The GAC filter significantly enhances the taste and odor of the water, making it more pleasant to drink.
  • Extended Filter Life: The dual-gradient design of the Polyspun filter helps protect the KDF-GAC filter by capturing a wide range of particle sizes, extending its lifespan and maintaining its effectiveness.
  • Protects Appliances: Reduces sediment and other impurities that can cause scaling and damage to plumbing and household appliances.
  • Overall Water Quality: Ensures that the water is clean, clear, and free from a wide range of contaminants, providing peace of mind regarding water quality.


Pentair Variable Density DGD-2501 Polyspun Filter

Purpose: This filter is a multi-density sediment filter. Benefits:

  • Dual-Gradient Filtration: Features a graded density structure that captures larger particles in the outer layer and smaller particles in the inner layer. This design optimizes filtration efficiency and extends filter life.
  • Improved Water Clarity: Effectively removes fine particles, sediment, rust, and other suspended solids, enhancing water clarity.
  • High Dirt-Holding Capacity: The dual-gradient design provides a higher dirt-holding capacity, meaning it can trap more contaminants before needing replacement.
  • Protects Downstream Filters: By capturing a wide range of particle sizes, it extends the lifespan of the subsequent filter by preventing it from clogging.

2. Pentair DBC-EX2 KDF-GAC Filter

Purpose: This filter combines KDF (Kinetic Degradation Fluxion) media with Granular Activated Carbon (GAC). Benefits:

  • Heavy Metal Reduction: KDF media effectively reduces heavy metals like lead, mercury, and iron.
  • Chlorine and Hydrogen Sulfide Reduction: KDF media reduces chlorine and hydrogen sulfide, contributing to better taste and odor.
  • Bacterial Control: KDF media inhibits the growth of bacteria, algae, and fungi within the filter.
  • Chemical Contaminant Removal: GAC is excellent at adsorbing organic contaminants, volatile organic compounds (VOCs), pesticides, herbicides, and trihalomethanes (THMs).
  • Improves Taste and Odor: Further enhances the taste and smell of water by removing additional contaminants.
  • Enhanced Filtration Efficiency: The combination of KDF and GAC improves overall filtration efficiency, providing cleaner and safer water.

We strongly recommend that a Pressure Regulator Valve be installed with this system in any mains water supply or when water pressure exceeds 100 PSI.


  • Twin housings Jumbo 10"  
  • 1 x Stainless Steel Bracket
  • 1 x Spanner for Housings
  • 1 x Pentair DBC10-EX2 (KDF GAC)
  • 1 x Pentair variable density sediment cartridge 25-1micron

Note: We will provide big blue housings when the grey-coloured housings as shown are unavailable at the time of order. Same quality different colour.

Pressure Drop: Pentair DBC10-EX2 filters typically experience a lower pressure drop compared to carbon block filters. This means they are less likely to significantly reduce water pressure in the system.
