Ultra-Fine Filtration Revolutionizes Water Filtration

Ultra-fine filtration technology is transforming the way we filter water. By removing contaminants down to an incredible 0.1 microns, this system eliminates the need for additional powered UV disinfection to tackle bacteria, parasites, and viruses. This is especially beneficial for homes with limited under-sink power outlets, as well as in caravans and campervans where access to power can be more challenging.

The unique “outside-in” filter design greatly extends the cartridge lifespan. However, it’s important to note that the dirtier the source water, the faster the filter cartridge will need replacement.
**Disclaimer: This system should not be used to filter water that is microbiologically unsafe or of unknown quality without proper disinfection.** We recommend dosing your water tank with a product such as Hydrosil Ultra 7.5% Water Sanitiser. This will ensure full protection against microbial contamination in your plumbing and filter system, as well as prevent biofouling within the filter itself.

Dual-Stage Filtration for Premium Rainwater Quality

Caware 0.1 Micron 3 in 1 Sediment Chemical Bacteria Reduction Filter

1st Stage: Caware 0.1 Micron 3-in-1 Sediment, Chemical & Bacteria Reduction Filter

This versatile filter cartridge provides comprehensive water treatment in a single stage:

5-10 micron pleated membrane removes sediment and turbidity 5 micron coconut carbon block reduces chlorine, chemicals, and pesticides
0.1 micron hollow fibre membrane filters out bacteria, viruses, and parasites

Independently tested to achieve a Log 8 reduction (99.999999%) of E.coli and P.aeruginosa. Complies with NSF/ANSI 42 & 53, FDA, and EU food-grade standards. 

Pure 5 Micron Silver Impregnated Coconut Carbon Block Water Filter

2nd Stage: Pure BCC 5 Micron Silver-Impregnated Coconut Carbon Filter

This high-performance coconut carbon block filter delivers exceptional contaminant reduction. Crafted using advanced manufacturing techniques, it provides superior filtration while maintaining low pressure drop.
Coconut carbon is renowned for its high micropore volume, enabling more efficient removal of disinfection byproducts like trihalomethanes compared to other carbon sources. The compressed block design maximizes surface area to adsorb contaminants like chlorine and chloramines.
The coconut shell raw material and production process ensure exceptional hardness and low ash content. This filter is registered to meet NSF/ANSI Standards 42, 53, and 61 for reducing VOCs, THMs, lead, heavy metals, chloramines, and chlorine taste/odour.
 Its infusion with microscopic silver particles gives the carbon an added antimicrobial property, making it effective at inhibiting the growth of bacteria, mould, and fungi within the filter.

Disinfection For Full Protection Against Bacteria

To ensure comprehensive sanitation against common water-borne bacteria and viruses in rainwater and potable bore water*, we recommend dosing your water source with a product like Hydrosil Ultra 7.5% Water Sanitiser.
*Potable bore water refers to water that has been tested and deemed suitable for drinking per the Australian Drinking Water Guidelines’ aesthetic, health, and safety recommendations.
Dosing your water with a disinfectant like Hydrosil Ultra will provide residual protection against microbiological contamination and biofouling throughout your plumbing and filtration system. This added layer of disinfection gives you full confidence in the safety and purity of your water.
Alternatively, for a continuous point-of-use sanitation solution, you may want to consider installing an Ultraviolet (UV) Water Sanitation system. This will further enhance the overall treatment and disinfection of your water supply.

Maximizing Water Purity: Why Tank Treatments and Inline Filters Work Better Together

While sanitizing your water tank is an important first step, it’s not sufficient on its own. Here’s why you’ll want to use both tank water sanitization and an additional rain water filter:

Tank water sanitization: – Sanitising the water in your tank helps kill any bacteria, microbes, or other contaminants that may be present but doesn’t prevent new contaminants from entering the water as it’s stored or runs through your plumbing.
Supplemental water filtration: – An under sink water filter for tank water that treats the water as it comes out of your tap provides an additional barrier against contaminants. – Filters like the one with the silver-impregnated carbon block can remove residual chlorine, chemicals, heavy metals, and any microbes that may have slipped through the tank sanitization process.   – This ensures the water you consume is as clean and safe as possible, even if new contaminants enter the system after the tank has been treated.

The combination of tank water sanitization and the best water filter for tank water is the best way to ensure your harvested rainwater or tank water is thoroughly purified. The filter acts as an extra safeguard, protecting you from anything that may have passed through the initial tank treatment. This “multi-barrier” approach is the most reliable way to consistently deliver clean, contaminant-free water from your tank or rainwater system.

Ultra-Fine Filtration for Homes with Water Tanks - Perfect for Campers and Motorhomes Too!

This ultra-fine water filter is not only great for your tank water at home but also the perfect water filter for camping, providing reliable, contaminant-free water on the road or in your motorhome.

• Enjoy the power of ultra-fine filtration that removes contaminants down to 0.1 microns. This eliminates the need for powered UV disinfection devices, which can be difficult to install in tight spaces like under sinks or in campers and caravans.
• The silver-impregnated carbon filter is designed to actively inhibit the growth of bacteria, even when not in use. This bacteriostatic feature helps prolong the life of the filter cartridge, making it an ideal choice for intermittent use in recreational vehicles.
• The filter is perfect for quick, convenient disinfection when traveling in a caravan or motorhome, providing you with peace of mind and clean, safe water on the go.
