PURONICS Sediment & Carbon Pre-Filter

SKU ICW-PRE-GAC Backordered(26)

The pre-filter does the heavy lifting so the stages behind it do not have to. It captures grit and rust while granular activated carbon takes chlorine out of the stream - the single most important cartridge for protecting the life of your reverse osmosis membrane.
