Sentry Water Filters + Reverse Osmosis

03/06/2026

Out of sight, out of mind? When was the last time you actually changed your water filter cartridges? If it has been more than a year, your system might be doing more harm than good.

A lot of Australian homeowners wait for a metallic taste or a drop in water pressure before ordering replacements. However, a neglected carbon filter can actually become a bacterial breeding ground, or cause structural stress and pressure drops that damage your home's plumbing.

Regularly changing your cartridges and UV lamps ensures that the invisible barrier between your family and tank or town water contaminants stays fully operational.

Don't wait for your water to look or taste dirty before you act. Read our full guide on the blog to spot the warning signs, or order your replacement kit directly through our website today.

Is there ammonia in your tap water?

If you live on the East Coast of Australia, your water treatment has likely changed. To keep water "safe" over long distances, ammonia is being added to create Chloramines.

The problem?. They are tougher to remove, stay in your water longer, and can even affect your home’s plumbing.

We’ve just released a full breakdown on:
1. The Standard Carbon Problem
2. The Reverse Osmosis Challenge
3. The Solution: Catalytic Carbon

Australia is tightening the rules on "forever chemicals," and your tap water is at the center of the conversation.

New 2026 regulations have slashed the acceptable limits for PFAS in our drinking water. While authorities in Brisbane, Sydney, and Melbourne work to catch up, these chemicals remain famous for one thing: they never break down. Over time, they bioaccumulate in our bodies, posing long-term health risks.

You don't have to wait for infrastructure changes to protect your home. Whether you need a simple renter-friendly benchtop filter or the molecular-level purity of Reverse Osmosis, we have the technology to strip these chemicals from your glass for good.

Think boiling your water is a total reset button? Think again.

While a rolling boil kills living nasties like Giardia, it does nothing to remove the chemicals and heavy metals hiding in Australian water. In fact, boiling can actually increase the concentration of toxins like lead and nitrates as the pure water evaporates away. True water safety requires a multi-barrier approach where you filter out the physical pollutants that heat simply can't touch. Check out our latest blog to learn why your kettle isn't a substitute for a high-quality filter.

Why Boiling Your Water Isn't Enough: Filtration vs. Sterilization When you look at a pot of boiling water, it is easy to assume that the bubbling heat acts as a total reset button for water purity. However, the reality of water safety in Australia is more complex than simple heat application. To und...

What’s hiding in your tank?

In Australia, our rooftops are highways for local wildlife. While we love our birds and possums, we don’t love what they leave behind in our drinking water.

From microscopic parasites like Cryptosporidium to the bacteria from a drowned lizard, your tank water needs more than just a mesh screen to stay safe.

Discover why UV Sterilisation and Reverse Osmosis are the essential "double-shield" for every Australian rainwater tank. Check out our latest article to see how you can upgrade your home's water security.

Is Your Drinking Water Safe from "Forever Chemicals"? PFAS, often called forever chemicals, are synthetic compounds that don't break down in nature or the human body. Recent 2026 reports have highlighted trace detections across Australia, from Sydney's Blue Mountains to groundwater zones in Perth, Brisbane, and Melbourne.
While authorities monitor these levels, many standard water pitchers aren't enough to remove these resilient pollutants. Reverse Osmosis (RO) technology offers a powerful solution by using a microscopic semi-permeable membrane to physically filter out up to 99% of PFAS contaminants.
Protecting your home with a multi-stage RO system ensures your family has pure peace of mind with every drop. Don't leave your water quality to chance when a reliable physical barrier is available for your kitchen.
