For 30+ years you have trusted Puratap for great tasting water.
The new Ultraguard Filter, developed with CSIRO and UniSA, adds next generation protection automatically included at your next service, at no extra cost.
Ultra guard filters reduce potentially harmful chemicals, scientifically validated by a registered independent and authorised laboratory.
*Independently tested by an ISO/IEC17025 accredited laboratory.
At Puratap, we’ve always believed in planning ahead, solving tomorrow’s problems before they reach your tap. That’s what drove the Ultraguard project.
We saw new chemical threats emerge and made sure your system could handle them.
That’s why we partnered with CSIRO and UniSA in an eight year, $1,000,000 research collaboration focused on safer, more effective household water filtration. The result is the Puratap Ultraguard Filter, world class protection included automatically at your next service, at no extra cost.
Recent Australian water headlines highlight the new problems
“Sydney tap water contaminated
with 31 different PFAS compounds,
21 previously undocumented in Australia”
UNSW STUDY, 2024
“PFAS detected at 16.4
ppt in Blue Mountains water supply”
SYDNEY WATER, 2024
“7,000 tonnes of microplastics found
in Moreton Bay sediments”
UNIVERSITY OF QUEENSLAND, 2024
“Australia updates PFAS
drinking water guidelines
with significantly stricter limits”
NHMRC, JUNE 2025
Our original filters set the benchmark for taste and purity. Now, Ultraguard takes that legacy further, defending against modern water threats without changing the taste you love.
Microplastics Filtration exceeded the standard by 110%
Microplastics are now detected in food, bottled water and even air samples. Although research into health effects is still developing, the World Health Organisation has called for urgent global study. Result: Independent testing showed Ultraguard captured particles down to 0.5 microns, delivering 110% higher removal efficiency than the NSF benchmark for microplastic reduction. That level of performance reflects the filter’s more uniform carbon structure, which holds smaller particles more consistently for the full service life. Change the filter between 11–12 months to maintain full performance.
Forever Chemicals (PFOS & PFAS) Below Detection Limits
PFAS compounds, often called “forever chemicals”, do not break down easily in the environment and can accumulate over time. They have been found in water supplies across Australia, prompting stricter national guidelines and warnings from the U.S. EPA and NHMRC. Result: Ultraguard reduced PFAS and PFOS levels to below the laboratory’s 5 parts per trillion detection limit, effectively undetectable under test conditions. The test confirms Ultraguard provides real world defence against one of today’s most persistent contaminants. Annual replacement ensures those results remain consistent.
Lead - Real World Protection
Lead in Australian mains water is rare, but household plumbing can be the hidden source. Older brass fittings and fixtures can leach trace amounts of lead into drinking water — a concern the Australian Building Codes Board is now addressing with new lead-free plumbing regulations. Puratap taps have been lead-free for over 20 years, and our next-generation models already comply fully with the new standards. Result: Independent testing showed the Ultraguard Filter reduced a lead spike from 0.01 mg/L to < 0.005 mg/L for its rated life (2,500 L / 12 months). While this does not qualify as an NSF “lead-removal cartridge”, it does demonstrate effective reduction to within the Australian Drinking Water Guidelines limit. We’re now retesting Ultraguard using a higher influent level of 0.06 mg/L, with early results indicating further improvement. If household lead levels exceed 0.01 mg/L, plumbing remediation is recommended rather than relying solely on filtration.
Trihalomethanes (THMs)
By-products of chlorine disinfection; the World Health Organisation lists some as possible carcinogens. Result: Our previous filters already removed THMs and 45+ VOCs. Ultraguard maintains that strength while improving consistency and longevity. Like every filter, Ultraguard must be changed between 11–12 months to maintain full performance. Protection fades as the filter fills, that’s why timely service matters.
Your loyalty deserves a reward.
Every Puratap filter has always used premium coconut shell carbon, the source of our famous crisp taste. Ultraguard keeps that freshness while adding the reassurance of advanced protection.
