Water Filter Systems Explained | Filtration Canterbury (NZ Guide)

Clean, Safe Drinking Water for New Zealand Homes & Farms

If you’re concerned about what’s in your water, you’re not alone. Across New Zealand—especially in rural areas like Canterbury—water can contain nitrates, bacteria, sediment, and chemicals that impact health, taste, and long-term safety.

At Filtration Canterbury, we design and install high-performance water filtration systems tailored to New Zealand conditions—ensuring your water meets NZ Drinking Water Standards (NZDWS) and protects your family, staff, or livestock.

What Is a Water Filtration System? (Simple Explanation)

A water filtration system is designed to remove contaminants by passing water through multiple treatment stages. Each stage targets different impurities to deliver safe, clean, great-tasting water.

Typical Multi-Stage Filtration Process

Stage 1: Sediment filtration (removes dirt, rust, silt)

Stage 2: Carbon filtration (removes chlorine, chemicals, taste & odour)

Stage 3: UV disinfection (kills bacteria and viruses)

Optional Stage 4: Reverse Osmosis (removes nitrates, fluoride, heavy metals)

This multi-barrier approach aligns with Water Safety Plan (WSP) principles and best practice across New Zealand.

Ensuring safer water - chlorination upgrades 2022

Water Filters specific to Selwyn Chlorinated water supply

I recently got a water filter of Filtration Canterbury and it works like a charm! The taste and smell of the water is so much better than before. I also noticed that my skin became less itchy.

I've been using their whole house filter for over a month now and I'm absolutely amazed by the results. My tap water has never tasted so good and smelled so fresh. In addition, I don't have to worry about the harmful effects of chlorine in my drinking water any more.

Even my pets seem to be drinking more now! Anyone who wants their family to drink more water, a good filter is a must. It is definately worth the money and highly recommend it to all my friends and family.
