Every drop counts—especially here in Australia, where water is as precious as a cool breeze on a scorching summer day. In support of National Water Week, we're taking a closer look at how we can all become better water custodians, and not just by using less water but by using it smarter. And the best place to start? Right at home.

When you think about how to save water at home, your brain probably jumps straight to the usual suspects: shorter showers and waiting for a full load of laundry. While those classic water saving tips Australia needs are essential, we're here to share a secret: one of the biggest helpers in your home can be your water filter.

Yes, seriously! At Earths Water, we believe that clean water and water conservation go hand-in-hand. By optimising the water you use, you actually end up using less of it.

Ready to become a certified 'Water Hero' without sacrificing your comfort? Here are 5 genius ways your Earths Water filters can help you save every drop.

1. Choose Filtered Water Over Bottled—Every Time

It’s one of the simplest swaps you can make, and one of the most powerful.

Australians buy billions of plastic bottles every year—most used once and tossed aside. That’s a staggering amount of waste (and energy) for something that literally flows from your tap. By switching to a water filter, you skip the single-use plastic, cut your carbon footprint, and enjoy better-tasting water in the process.

Our Glass Benchtop Filter turns ordinary tap water into crisp, pure hydration without chlorine, heavy metals, or microplastics. You get all the convenience of bottled water, minus the guilt (and the endless recycling).

It’s sustainable hydration made simple—and it saves hundreds of bottles every year.

2. Store Smarter: Keep Cold Filtered Water Ready to Go

We’ve all been there: reaching for the tap only to let it run for a few seconds until it’s “cold enough.” Those seconds? They add up.

According to the NSW Government, households can waste up to 5 litres of water per minute just waiting for the tap to cool. But there’s an easy fix: store filtered water in the fridge.

Our 3.5L Glass Carafe Water Filter and Water Filter Jugs keep your water fresh, chilled, and ready when you are. No running the tap, no waste, just clean, cool water on demand.

Plus, both look great on the table when you’re entertaining (bonus points for style).

3. Cook and Clean with Filtered Water (and Save More Than You Think)

Here’s one most people overlook—the water you use for everything else.

Filtered water isn’t just for drinking. When you cook rice, wash produce, or make tea, unfiltered tap water can introduce chlorine, sediment, and other trace contaminants into your food. That not only affects flavour but can also impact how your food reacts during cooking.

By filling your pans and kettles with filtered water instead, you’re not only getting better taste—you’re avoiding wasted batches of cloudy ice, off-tasting tea, or over-boiled veggies. It’s a subtle way of saving more by wasting less.

And when cleaning, a small tip: collect your rinse water in a tub instead of letting it go down the sink; it’s perfect for watering plants.

4. Install a Home Filter System and Cut Down on Waste at the Source

If you’re ready to take things up a notch, a filtered water system under the sink might just be the ultimate investment.

Our Under Sink Reverse Osmosis Water Filter gives you instant access to purified water whenever you turn on the tap without the bulky bottles or countertop clutter.

Each filter prevents up to 58kg of CO₂ emissions over three months (the equivalent of driving around 230km in an average car). Multiply that across a year, and you’ve got some serious eco points.

And with a tankless design and easy cartridge replacements, it’s one of the simplest and most space-efficient systems out there.

5. Hydrate Intentionally—and Use Every Drop

Sometimes saving water isn’t about what you don’t use—it’s about making the most of what you do.

Fill your reusable bottle before heading out. Use the leftover water in your carafe for watering herbs or rinsing dishes. Even the condensation in your fridge tray can go towards houseplants!

And here’s the bigger picture: according to the Australian Bureau of Statistics, the average household uses around 340 litres of water per day. Just a 5% reduction across households nationwide could save millions of litres each year—enough to fill the Sydney Olympic Pool for more than 50 times.

When you start looking for those little moments to save, it quickly becomes second nature.

Stopping the Flow of Embedded Water

This one is a little meta, but incredibly important, especially for water saving tips. It’s about the hidden water usage known as embedded or embodied water.

Think about how much water is used just to make one single plastic water bottle. It takes several litres of water to manufacture the plastic, process the petroleum, and fill, package, and transport just one litre of bottled water.

By choosing Earths Water filters, you completely eliminate that massive embedded water footprint. One Earths Water filter cartridge can replace hundreds of plastic bottles—that's hundreds of times you've saved all that manufacturing water!
