Advanced Nanofiltration technology in 5 stages
Our Tap Water Filter operates with 5-stage Advanced nanofiltration technology

1- Polypropylene mesh
Wrapped around the carbon block, it filters out the largest micro-organisms, sediment, rust, scale and other impurities. It also prevents human hands contaminating the carbon block when replacing it.
2- Activated carbon adsorption
The activated carbon made from coconut shells removes organic chemical matter at nanoparticle level incl chlorine, chlorine byproducts (VOCs, THMs, HAAs, etc.), tastes, odours, pesticides, herbicides, PFAs and over 80 other contaminants. It also reduces the quantity of heavy metals like lead, copper and mercury, among others.
3- Carbon block microfiltering
The activated carbon made from coconut shells removes organic chemical matter at nanoparticle level incl chlorine, chlorine byproducts (VOCs, THMs, HAAs, etc.), tastes, odours, pesticides, herbicides, PFAs and over 80 other contaminants. It also reduces the quantity of heavy metals like lead, copper and mercury, among others.
4- Removes limescale and heavy metals
The carbon block houses our patented formula, the result of long years of research and of which we are extremely proud. It breaks down the mineral to prevent limescale forming, as well as trapping any remaining heavy metals.
5- Sieve
Filters out hair, sand, dirt and other impurities commonly found in household water pipes.
FAQ
How does installation work?
It’s super easy—no tools, no plumber, just clean water in seconds.
Unscrew the little cap at the end of your tap—that’s called an aerator, but don’t worry about the name. Just twist it off.
Screw the filter on where the aerator was. If it fits right away, great! If not, use one of the 5 adapters we include—we’re pretty sure one of them will work.
Flip the switch to choose between filtered and unfiltered water.
We include 5 different adapters to fit most taps, so chances are, you’re covered. But if none of them fit, just message us, and we’ll send you the right adapter free of charge.
Still unsure? Watch our quick setup video for a step-by-step guide.
That’s it. No hassle, just clean water.
How much does maintaining the filter cost?
Running a Tap Water Filter is incredibly affordable—far cheaper than buying bottled water.
Getting started:
Our Starter Pack ($129.99) includes a filter and one refill, lasting 2 months. For the best value, our Annual Pack ($259.99) comes with a filter and 6 refills, lasting a full year.
Ongoing costs:
Our Annual Refill Pack ($149.99) includes 6 refills, lasting 12 months. Or, subscribe and save 15%, paying just $127.49 per year with free shipping and a lifetime warranty.
To put it in perspective, a 600ml bottle of water costs $2.35 at Woolworths—that’s $3.92 per litre. With the Tap Water Filter, you pay less than 10 cents per litre—almost 40x cheaper than bottled water. That’s just $10.60 per month for unlimited clean water, no plastic waste, and no unexpected costs. Plus, with our lifetime warranty for subscribers, your filter is covered forever.
Why overpay for bottled water? Make the switch today!
What contaminants does the filter remove?
Water might look clean, but it can hide all sorts of unwanted stuff—things you can’t see, smell, or taste. That’s where the Tap Water Filter comes in.
Let’s talk about the big ones:
PFAS ("Forever Chemicals") – These nasty chemicals don’t break down easily and have been linked to health issues. Our filter removes over 95% of PFAS, so you’re not drinking what your body doesn’t need.
Microplastics – Tiny plastic particles are showing up in water everywhere. Our filter removes 99.9% of microplastics, so you’re not swallowing bits of plastic with every sip.
Chlorine & Chloramine – These are added to disinfect water, but they can leave a bad taste and smell. The filter knocks out over 98% of chlorine, giving you cleaner, fresher water.
Heavy Metals (Like Lead & Mercury) – You don’t want these in your water, and our filter removes them to safe levels.
Pesticides & VOCs – Chemicals from farming and industry? Gone.
Bacteria & Cysts – Helps reduce harmful microorganisms so your water is safer.
So, in short—it removes the bad stuff and keeps the good stuff, giving you clean, great-tasting water straight from your tap.

Will the filter affect my water flow?
Not really—our filter is designed to be fast, with a flow rate of 4 litres per minute, which is one of the fastest available.
Think of it like this: if you put a strainer under running water, it slows things down a little, but water still flows through quickly. Some filters are too dense and reduce the water to a trickle, but ours is optimised to remove contaminants while keeping the water flowing fast. So, you’ll barely notice a difference—except for cleaner, better-tasting water!
How long does each refill last?
That depends on how much water you use, but here’s a simple way to think about it.
Each refill lasts about 220 to 300 litres. If you're a small household or just using it for drinking water, that’s around 2- 3 months of clean water before you need a new one.
But if you’re a big family, filling up bottles, cooking, and using it all day long, you might go through refills faster.
To make life easy, we send email and SMS reminders (if you opt in) to let you know when it’s time to change the filter—so you don’t have to keep track.
If your water starts tasting off or slows down, that’s another sign it’s time for a new refill. Just swap it out, and you’re good to go. Clean water, no guesswork.
What is the filter made of?
The filter is made from high-grade ABS plastic because it is strong, lightweight, and resistant to rust and corrosion. Stainless steel may seem like an alternative, but it is heavier, more expensive, and can corrode over time—making it less practical for a tap-mounted water filter.
Now, can it break? It’s rare, but possible. Nothing is indestructible. But if something goes wrong, we replace it for free. Because the important thing isn’t just the material—it’s making sure you have clean, safe water, guaranteed.
Why can't I use the filter with hot water?
Hot water can damage the filter, reduce its effectiveness, and even cause the housing to crack or burst. The activated carbon inside is designed for cold or lukewarm water, and high temperatures can release trapped contaminants instead of filtering them out. Heat also reduces the filter’s ability to remove chemicals like chlorine, PFAs, and VOCs, while weakening the plastic, which can lead to leaks or even structural failure.
To prevent damage, your Tappwater filter has a switch that lets you toggle between filtered and unfiltered water. If you need hot water for cleaning or washing dishes, simply switch to unfiltered mode to protect the filter and avoid any risk of damage.
What if I’m not satisfied with the filter?
We want you to love your Tappwater filter! If you're not completely satisfied, we offer a 30-day money-back guarantee with free returns—no questions asked. Just reach out to us, and we’ll make the return process quick and hassle-free.

Tips for looking after your filter
Best Practices for Optimal Use and Disposal

Only use the filter with cold water
When using hot water, ensure the lever is set to the "unfiltered water position" to prevent damage to the filter.
Don't clean the filter with soap
Avoid cleaning the filter with soap or detergents, as they can degrade its performance. Simply rinse it with water and wipe down if necessary.
Flush after inactivity
If your filter hasn’t been used for a few days, allow the water to run through the filter for at least 30 seconds before using it. This ensures optimal filtration.
Keep Away from Heat
Do not expose the filter to high temperatures, as heat can compromise its effectiveness.
Properly Dispose and Recycle
When replacing your filter, separate the components. The plastic parts can be recycled, but the carbon block should be disposed of with regular waste, as it has absorbed contaminants.
30-Day Money Back Guarantee

Our mission is to make clean water available to everyone.
If you’re unsatisfied with your filter for whatever reason you can return it for a full refund within 30 days. No questions asked.
