Carbon Filters

Carbon filters are an effective way to remove chlorine & organics from water and enhance its taste. Our carbon block & GAC filters are compatible with the majority of 10” housings and standard RO systems available on the market. We recommended changing them every 6 months depending on usage.

So whether you require a wound, spun, or pleated filter, we have a solution available. We recommended changing them every 6 months depending on usage.

Reverse Osmosis Membranes

A membrane is the heart of an RO system removing contaminants such as fluoride, calcium, magnesium, lead, colloids, chromium, and nitrates. We sell reverse osmosis membranes made from 100% food-grade Thin Film Composite (TFC) material for ultimate purification performance with high permeate flow. We recommended changing them every 1-2 years.

Taste & Odour Filters

Taste and odour filters improve the taste of water and are often used as a post-filter on reverse osmosis systems. It clips onto the membrane housing and will filter the water after the tank, acting as a polishing filter. These filters can also be used in other applications such as water coolers, coffee machines, and fridges.
