The Seagull® IV X-1F Water Purifier is a compact under-sink water purifier designed to change any treatable non-salt water into pure drinking water. It is independently certified to meet the US EPA Standard for Microbiological Purifiers removing Bacteria, Cysts and Viruses from your tap water.


The Seagull IV removes heavy metals, pesticides, fertilisers and other contaminants leaving you with just fresh pure water. It employs the proven "Structured Matrix" technology and delivers water safe enough to give a 2 month old baby.


There is no bacteria growth in the cartridge and the water purifier is made from marine grade stainless steel with lead-free faucets/spouts and ports.


Unlike other purifiers (such as reverse osmosis), the Seagull IV Water Purifier retains valuable minerals and electrolytes in the water.


With the Seagull IV Water Purifier you can drink any water source without using chemicals, electricity or wasting water.


The Seagull IV X-1F water purifier provides pure crystal clear drinking water for homes, offices, hospitals, aviation, yachts, boats, schools, or RVs. Simple to install and operate. (See our FAQ for installation instructions) Note: It is not a desalination unit.
