Which Tap Is Right for You?

Which Tap Is Right for You?

You’ll need a way to dispense your RO water. The P500 gives you two options:

Option 1: 3-Way Mixer Tap

  • Connects directly to a 3-way kitchen tap (hot, cold mains water + pure water).
  • No extra faucet hole needed.
  • Choose from our premium finishes or use your existing 3-way tap.
  • Kit includes all fittings to hook it up.

Option 2: Dedicated Smart Faucet

  • Comes standard with the P500.
  • Connects to the TDS Sensor & cartridge lifespan.
  • Installs in a 28mm sink/counter hole (like a soap dispenser).

Already have a filtered tap or 3-way mixer?

Simply connect the P500 to it and use it for purified water only.

HOW IT COMPARES

Not all filtration is equal. The data makes it clear.

Most filters reduce taste and odour. Only reverse osmosis removes what you can't see.

Australia's Only WaterMark Certified Tankless RO System

Your family deserves water you don't have to think twice about.

The P500 removes 99% of what's in your tap: PFAS, lead, microplastics and fits under sinks as narrow as 380mm. No tank. No bacteria risk. No guesswork.

You've done the research. This is what it found.

You Ditched the Tap. But the Plastic Stayed

You stopped trusting the tap. So you switched to bottled water.

But every plastic bottle delivers up to 240,000 microplastic particles per litre, straight into your family's glass. Unregulated. Invisible. Accumulating.

The P500 removes 99% of microplastics from your tap. No bottles. No plastic. No compromise.

Better water. $2,800 a year back in your pocket.

No Tank. No Wasted Space. No Compromise

Traditional RO systems need a tank. Tanks take space, store water, and breed bacteria between uses.

The P500 is tankless. 60% smaller than traditional systems. Instant flow, no waiting for a tank to refill.

No mounting brackets. No drilling. Stand it upright or lay it flat, wherever it fits, it works.

Remove the Nasties. Restore the Minerals

Most filters stop at the nasties. The P500 goes further.

Seven stages remove PFAS, lead, chlorine, and heavy metals, down to 0.0001 microns. Then alkaline remineralisation adds calcium and magnesium back. Pure water that actually tastes good.

The result: water your family chooses. Coffee that tastes right. A kettle that stays clean.

Pure Water, Not Empty Water

Standard RO removes the nasties. It also removes the minerals your body needs.

The P500 adds them back. Calcium, magnesium, and potassium restored. pH balanced to 8+. Water that's pure, not stripped. Clean, not acidic.

Not dead water. Crisp, alkaline water your family actually chooses to drink.

30 Second Filter Changes No Tools No Mess

Transparent maintenance costs. Smart reminders. Nothing hidden.

Twist off, twist on cartridges. 30 seconds to swap. No tools, no call outs required.

Annual cost: ~$299 that's $2,500 less than bottled water.

Smart alerts remind you. Filters ship to your door. You never think about it.

Your Way: 30 Minute DIY or Professional Installation

Tap requirement: The P500 requires a dedicated tap. Use the included dual function tap (28mm hole) or connect to an existing 3-way mixer tap. It cannot connect to standard kitchen taps.


Seven step installation: mount feed adaptor (3/8" tubing), drill and install faucet (28mm hole), attach drain clamp, connect four water ports, plug in power, flush system

DIY install: 30-45 minutes with wrench and drill. Or hire any plumber ($150-300 typical).

    Beautiful tasting water!

    We’re absolutely thrilled with this filter! It fits perfectly under the kitchen sink, and the clear, easy-to-read dial makes it simple to know when it’s time to replace the filters. We opted for a separate 3-way tap so we could avoid drilling an extra hole for the filter faucet.

    Even though my husband isn’t a plumber, he was able to install it himself without any trouble. The taste of the water is incredible—we can’t believe we didn’t get this sooner!

    Got Questions?

    How does the money-back guarantee work?

    30 days from delivery. Contact our team by phone or email, we'll arrange return pickup at our cost. No restocking fees. No forms. No requirement to explain yourself. Refund to your original payment method within 5 business days.

    check_box

    What's covered under the warranty?

    One year, covering the housing, pump, fittings, and all included components. If anything fails, we replace it, no repair delays, no third-party service centres. All claims handled directly by AQUALA's Australian support team. Filter cartridges are consumable items and sit outside warranty coverage, but they're always in stock for fast delivery.

    check_box

    Will it fit under my kitchen sink?

    Almost certainly. The P500 measures 37cm × 14cm × 44cm, roughly two shoe boxes stacked. It's 60% smaller than tank-based RO systems, fits cabinets as narrow as 380mm, and positions upright or flat. No drilling. No mounting brackets. If it fits a shoe box, it fits your sink.

    check_box

     Does it actually remove PFAS?

    98% PFAS reduction, verified by independent third-party testing. PFAS molecules are larger than the RO membrane's 0.0001-micron pore size, they're physically blocked, not chemically treated. Download the full NATA lab results from this page and see the data yourself.

    check_box

    How often do I change the filters & which ones?

    The P500 uses 3 filters with different lifespans:

    1. Every 6 months: PPC filter (catches dirt, rust, chlorine)
    2. Every 12 months: T33 filter (adds minerals, makes water alkaline)
    3. Every 24 months: RO membrane (removes heavy metals, fluoride, PFAS)

    Don't worry about tracking dates, the system's smart alerts tell you exactly when each filter needs changing.

    Changing filters is ridiculously easy: Just twist off the old one, twist on the new one. Takes 30 seconds, no tools needed.

    check_box

    How will I know it's time to replace the filters?

    The system tells you automatically.

    The filter replacement is based on a preset time schedule. The P500 system automatically notifies you when each filter is due for replacement. There’s no need to manually track dates, the system is programmed with smart filter alerts that remind you when it’s time to change each filter.

    Simple as that, you'll know exactly when to change each filter without thinking about it.

    check_box

    Where can I buy replacement filters?

    Directly from AQUALA.

    Order replacement filters through our website, give us a call, or contact our support team. We keep all filters in stock for fast delivery across Australia.

    Easy reordering, no hunting around for compatible filters from random suppliers.

    check_box

    Can I use my existing tap or do I need a separate faucet?

    You need a separate tap for your filtered water. Two easy options:

    Option 1: Use a 3-Way Mixer Tap
    If you have (or want) a 3-way kitchen tap, the P500 connects directly to it. No extra holes needed, your existing mixer dispenses pure water alongside hot and cold mains water.

    We sell matching 3-way taps in various finishes, or you can use your existing one. The kit includes all connectors to hook it up.

    Option 2: Dedicated Dual-Function Faucet (Included)
    The P500 comes with a sleek dedicated faucet that gives you:

    • Filtered water: For dishes and general use (basic filtration, only goes through the first stage)
    • Purified water: For drinking and cooking (full RO treatment)

    Installation: Just drill a 28mm hole in your sink (like installing a soap dispenser) and secure the faucet. Takes minutes.

    Already have a filtered water tap or 3 way tap? Connect the P500 to it and use it for pure water only.

    check_box

    How does reverse osmosis work?

    Reverse osmosis pushes water through an ultra-fine membrane that blocks contaminants.

    Think of it like the world's finest screen, only pure water molecules can pass through, while PFAS, fluoride, heavy metals, and other nasties get flushed away.

    Here's what makes tankless different: Traditional RO systems filter water slowly and store it in a tank. The P500 filters water instantly as you use it, no storage, no waiting, always fresh.

    The system uses pressure to force water through the 0.0001-micron membrane (that's 500 times finer than a human hair), then adds healthy minerals back before it reaches your tap.
