Puretec Hybrid series: two layers of protection for superior water quality
The Dual-Stage Filtration System in the Puretec Hybrid G8 provides a powerful first line of defence, ensuring your water is clean, clear, and free from unwanted impurities before it even reaches the UV stage. The first stage captures larger particles, such as dirt, rust, and sediment, protecting your plumbing and appliances from premature wear and tear. The second stage further refines your water by trapping finer particles, thereby improving clarity and overall water quality. This two-stage process not only enhances the efficiency of UV sterilisation but also extends the life of your entire filtration system. The result is consistently pure, great-tasting water for your whole home — whether you’re drinking, cooking, showering or doing laundry.
Designed for NZ homes and weather — Durable. Reliable. Puretec.
Built for New Zealand’s unique water sources and harsh weather conditions, the Puretec Hybrid G8 is designed to deliver reliable, long-lasting performance — no matter where your water comes from. Whether you're drawing from rainwater tanks or mains water supplies, this system ensures consistently safe, clean water for your entire household. Puretec’s robust construction, featuring a corrosion-resistant aluminium bracket and weather-protective cover, withstands the diverse climate challenges New Zealand homeowners face — from coastal salt air to heavy rainfall and summer heat. The Hybrid G8 is engineered for durability and year-round performance, providing you with total confidence in your water quality.

Steve's Pros & Cons
Pros of the Puretec Hybrid G-7 UV Filtration
Why choose the Puretec Hybrid G7 UV Filtration System for your home
If your home runs on rainwater or needs reliable, low-maintenance water treatment, the Puretec Hybrid G7 UV Filtration system brings added convenience, protection, and long-term performance. It’s ideal for medium—to large households that want cleaner water and fewer filter hassles.
Puretec Hybrid G7 whole house water filter with larger cartridges
What sets the Puretec Hybrid G7 whole house water filter apart from smaller models like the G6 is its oversized 20” x 4.5” cartridges. These filters trap more sediment and absorb more taste and odour compounds — meaning fewer changeouts, better flow retention, and improved efficiency over time.
Radfire™ UV Light for safe, drinking water
The system uses Puretec’s Radfire™ UV technology to neutralise up to 99.9% of harmful microorganisms, including E. coli and Giardia. It’s a proven, chemical-free method that keeps water safe without compromising taste.
Puretec UV filter designed for harsh NZ Conditions
The Puretec Hybrid G7 Ultraviolet water filtration system is housed in a weather-tough aluminium bracket with PVDF coating. It includes a tamper-proof lid and an integrated UV lamp timer with an alarm. It is designed for long-lasting performance—even when installed outside.

Cons of the Puretec Hybrid G-7 Filtration
Puretec Hybrid G-7: A larger size means more installation space is required
The G7’s higher-capacity 20” filters are great for performance but also make the unit physically bigger. That means you’ll need more space for installation. This could be a challenge if your pump shed is already tight or you’re replacing a smaller system.
Vertical setup needed for this whole house UV water filter
Like other Puretec Hybrid systems, the G7 requires a vertical setup. While that’s standard in most homes, it limits placement flexibility — especially if you’re dealing with wall mounts, tight corners, or sloped sheds. If space is a concern, another model might be better suited.
Sun protection recommended for this outdoor UV water system
Even though this Puretec UV filter is designed for outdoor use, prolonged exposure to direct sunlight can degrade the filter housings. We always recommend using a protective cover — especially in high UV zones — to extend the unit’s life and avoid premature wear.
Puretec UV system servicing requires extra care and expertise
While basic filter changes are easy, servicing the UV chamber — particularly handling the quartz sleeve — is best left to a technician. The sleeve is fragile, and incorrect handling can cause breakage or leaks. We always advise booking a professional for annual maintenance.
Still deciding if the G7 suits your setup? Call our team on 0800 278 288 for expert advice. We’ll help you weigh the pros and cons and find the best fit for your household and water supply.
