The Best Value For Money Under Sink Water Filter System.
  • This system uses the latest mini-filter from 3M/Cuno, with a quick twist fit for an easy and dry six-monthly filter change.
  • The AP2-C405-SG is one of the most versatile filters in the market. It has a 0.5-micron carbon block, making it bacteria rated.
    It has heavy metal removal media, allowing metals such as lead to be removed from the water.
  • The SG in the model refers to scale reduction, meaning it contains polyphosphate which is a scale inhibition media.
    Finally, the carbon block main body is highly effective at removing Chlorine which removes the foul taste, smell and odour attributed to it as well as particulate sediment and suspended solids from the water.
    All this is a space-reducing compact filter with a larger capacity.
  • This filter is perfect for those looking for a compact filter unit that handles most of the water’s worst contaminants. You can be sure with this filter, most bases are covered and you will be receiving some of the best quality water that can be produced from a water filter. Replacement cartridges are relatively inexpensive due to the specification of the filter, and the ttwist-fitcartridge makes filter changes quick and dry.
