These advanced filters efficiently remove unpleasant tastes, odours, chemicals, and sediment—providing great-tasting water for drinking, cooking, bathing, and more. Experience the convenience of filtered water throughout your home while
How often should I replace my filters?
For an average NZ family on a two filter system with a UV Light we sugget changing your filters every 13,000L or minimum every 6 months
Signs It’s Time to Change:
- Reduced water pressure
- Unpleasant taste or odor returns
- Cloudy or discolored water
- Its been in use for 6 months
What systems are Ultra Filters compatible with?
Our filters fit all standard 10 inch systems in New Zealand. If you find that they dont we provide a full refund
Whats the diffirence between a Pleated and Carbon filter?
🌀 Pleated Filter
- Purpose: Removes physical particles like dirt, sand, rust, and silt.
- Material: Made of folded (pleated) polyester or cellulose.
- Function: Acts as a mechanical barrier—traps larger particles from entering your system.
- Lifespan: Typically lasts 6 months depending on water quality.
- Best For: First stage of filtration; protects other filters (like carbon or UV) from clogging.
🧪 Carbon Filter
- Purpose: Removes chlorine, taste, odour, chemicals, and some organic compounds.
- Material: Made from activated carbon (block or granular).
- Function: Works via adsorption—chemicals and contaminants stick to the carbon surface.
- Lifespan: Usually 6 months
- Best For: Second or third stage in a system; improves taste and odor, and protects
What is a Micron?
A micron is a unit of measurement describing the pore size of a water filter. The micron rating of a sediment filter determines the contaminants it can remove. The smaller the Micron the smaller the particle size the filter will remove
What Micron should I use?
Recommended Setup by Water Source:
Town/City
- Start with 10 Micron Pleated Filter → then a 1 Micron Carbon Filter (removes sediment + chlorine/taste)
Rainwater/Bore
- Start with 20 Micron Pleated Filter → then a 5 or 1 Micron Carbon Filter (removes sediment + chlorine/taste and UV light, larger and more filtration needed due to organic matter
Use multiple stages: always start with a larger micron (10-20 Pleated Filter) to catch big debris, then go finer (1–5 Carbon Filter) to catch smaller particles. This improves performance and extends filter life
Should I use a UV Light on my system?
Using a UV light in your water filtration system is important because it provides an extra layer of protection, specifically targeting microorganisms that other filters may not remove. Here’s why you should consider it:
1. Kills Harmful Microorganisms
UV light destroys up to 99.99% of bacteria, viruses, and protozoa (like E. coli, Giardia, and Cryptosporidium) without adding any chemicals to the water.
2. Chemical-Free Disinfection
Unlike chlorine or other chemical treatments, UV doesn’t leave any taste, odor, or by-products in the water.
3. Safe and Immediate
UV disinfection works instantly as water passes through the chamber, making it a reliable, on-demand method of ensuring microbiologically safe water.
4. Protects Against Boil-Water Alerts
In rural or rainwater-fed systems, UV systems are a safeguard against pathogens that may contaminate your supply, especially during heavy rains or pipe breaks.
5. Low Maintenance
Once installed, UV systems require minimal upkeep—usually just an annual bulb replacement
How cost effective are Ultra Filters?
In short, very cost effective. If you had a two filter system comprising of one Pleated and one Carbon filter and used 13,000L the cost per Litre would be $0.005 or half a cent!
How long does shipping take?
All domestic parcels will only take 3-4 working days to arrive
How does the subscription work?
Every 6 months we will send your specified filters out to you, you can change the filters or cancel at any time
