The Real Issue
Most Families Don't Know What's Actually in Their Water
Australian tap water is treated but treated doesn't mean pure. What reaches your taps still contains chemicals and compounds that affect your health, your skin, your appliances, and how your water tastes every single day.
Concerns
Chlorine and chloramines used in water treatment don't fully dissipate before reaching your home.
Heavy metals, sediment, and hard minerals stress your appliances and reduce their lifespan.
Dry skin and damaged hair after showering is often a direct response to unfiltered water not your products.
Children are more sensitive to chemical exposure in water than adults especially during bathing.
Under-sink filters only treat drinking water. Your shower, laundry, and dishwasher remain unprotected
"I thought our water was fine until we tested it. What came back changed how we think about every shower our kids take." ~ Parent of two, Perth homeowner
What We Deliver
You're Not Buying a Filter. You're Buying Peace of Mind.
Every Nexa system is built around what your family actually needs not a standard product off a shelf.
Safer Water for Your Family
Reduce chlorine, heavy metals, sediment, and chemical contaminants across every tap in your home. Protection for the water your children drink, bathe in, and cook with.
Healthier Skin & Hair
Filtered shower water removes the harsh chemicals that strip natural oils. Families consistently notice softer skin and healthier hair within weeks of installation.
Better Tasting Water
Chlorine is the primary reason tap water tastes and smells like a swimming pool. Remove it and the difference is immediate from every glass, every coffee, every meal.
Appliance Protection
Hard water and mineral buildup silently destroy hot water systems, dishwashers, and washing machines. Filtered water extends appliance lifespan significantly.
Whole-Home Coverage
Unlike under-sink filters that protect only one tap, Nexa systems filter every point of entry kitchen, bathroom, laundry, and outdoor from one installation.
Long-Term Health Confidence
Reduced daily exposure to waterborne chemicals supports long-term wellbeing. Many health-conscious families describe it as one of the most impactful home upgrades they've made.
Our Story
Nexa Didn't Start as a Business. It Started as a Question.
It started at home.
Like most Perth families, we assumed our water was fine. It met the standards. It came from the tap. It looked clean.
But our kids kept getting dry skin that wouldn't respond to creams. The water tasted off. The kettle was building up scale faster than it should. Small things but they added up.
So we looked into it. We tested the water. And what we found changed everything.
Perth's water is some of the hardest in Australia. High in minerals, treated with chlorine and chloramines that don't fully dissipate before they reach your taps. Fine by regulatory standards but far from what you'd choose to bathe your children in every single day if you knew what was in it.
When we started looking for solutions, we hit a wall.
Every company we spoke to sold one system. Their system. It didn't matter what our water tested at, what our home was like, or how many people lived in it the answer was always the same product, the same pitch, the same price.
We didn't trust it. And we couldn't find anyone who would just give us honest advice.
That's why Nexa exists.
Clean water isn't a luxury. It's the baseline every family deserves. Nexa exists to make sure Perth homeowners can access it with advice they can trust, from people who genuinely give a damn.

Testimonials
What Others Are Saying
After two years of dry skin and trying every moisturiser possible, our Nexa assessment showed our water was the problem. Three weeks post-installation genuinely different. I wish we'd done this sooner.
Sarah M. | Mother of two · Perth, WA
We moved into a new build and wanted to understand our water before unpacking. The assessment was thorough, the team wasn't pushy at all, and the system they recommended was perfectly sized. Exactly what we needed.
James K. | Homeowner · Perth, WA
I was sceptical, I thought whole-home filters were a luxury. The free assessment showed hard water minerals were destroying my appliances. The ROI on this system versus replacing another hot water unit made the decision easy."
Rachel T. | Homeowner · Perth, WA

Frequently Asked Questions
Is Australian tap water actually unsafe?
Australian tap water meets government safety standards — but 'safe' and 'optimal' are different things. Treatment chemicals like chlorine and chloramines are added during processing and remain in the water that reaches your taps. Hard water minerals, sediment, and other compounds vary significantly by region and property. A water assessment tells you exactly what's in your water.
What's the difference between a whole-home filter and an under-sink filter?
An under-sink filter protects one tap — typically your kitchen drinking tap. A whole-home system filters every point of water use in your house: showers, baths, laundry, dishwasher, kitchen, and outdoor taps. If skin irritation, appliance protection, and chemical reduction matter to you, a whole-home system is the only solution that addresses all of them.
How much does a whole-home water filtration system cost?
System cost varies depending on your home size, water quality, and household needs. That's exactly why we start with a free in-home assessment before recommending anything. We don't quote a price until we've tested your water and understood what your home actually requires. What we can guarantee is that there are no hidden charges — pricing is transparent and agreed before installation begins.
Is the free assessment genuinely no obligation?
Yes — completely. There is no call-out fee. There is no expectation that you will purchase anything. You'll receive a written summary of your water quality findings regardless of whether you proceed. Many homeowners book an assessment purely to understand their water, even if they're undecided on next steps.
How long does installation take?
Most whole-home filtration systems are fully installed in a single day by our certified technicians. Larger or more complex installations may require a second visit. You'll receive a clear timeline as part of your quote before any work begins.
What ongoing maintenance is required?
Filter cartridges require periodic replacement — typically annually, depending on your household water usage and system type. Nexa provides an ongoing maintenance and support service so you're never left managing this alone. We'll remind you when it's time and handle replacements as part of your ongoing support arrangement.
What areas do you service?
Nexa currently services metropolitan Perth and surrounding regions. Enter your suburb in the assessment booking form and we'll confirm coverage for your area. We're expanding our service footprint contact us if you're outside current coverage and we'll advise on expected availability.
Our Satisfaction Guarantee
If the installation doesn't meet your expectations, we return and make it right - no arguments, no delays, no additional cost to you. Every Nexa system is backed by this promise, full stop.
