Filtered water isn’t just for fancy fridges or sipping with a slice of lemon or cucumber. While we’re all for staying hydrated, your water filter has so much more to give, and not just in the kitchen.

Around your home, filtered water can quietly improve everything from plant care and skincare to how long your appliances last. These unexpected uses of filtered water at home don’t require a major lifestyle shift—just a little habit tweak here and there. And the best part? You’ll feel the difference in ways you didn’t quite expect.

Here are some genuinely useful and often overlooked uses of filtered water throughout your home.

Better Water for Your Houseplants

Many indoor plants are sensitive to chlorine and other chemicals commonly found in tap water. Over time, these can affect growth, cause tipping or the drying out and browning of the tip of leaves, and leave mineral spots on foliage.

Using filtered water gives your plants a gentler, more consistent supply of hydration. This is especially helpful for indoor plants that thrive with a little extra care.

Earths Water Tip: Keep a water filter jug or glass carafe near your plants so watering becomes part of your regular routine. 

Cleaner Water for Pets

We often think about what we’re feeding our pets, but their water matters too. Just like humans, pets can be sensitive to chlorine and other additives in tap water.

Filtered water removes many of these chemicals, offering a cleaner, better-tasting option. It can support digestion and help sensitive stomachs. You might even find they drink more, which is always a good thing.

Earths Water Tip: Use our glass carafe to top up your pet’s water bowl each morning. It’s an easy habit to get into—and one they’ll appreciate, even if they can’t say so.

A Gentler Rinse for Your Face

If your skin often feels dry or tight after rinsing, the issue might not be your cleanser—it could be the water. Tap water can contain chlorine, fluoride, and minerals that disrupt your skin’s natural balance.

Filtered water is much gentler and ideal for rinsing after cleansing, especially for sensitive or eczema-prone skin. Some people even notice fewer breakouts or reduced redness when switching to filtered water for their face.

Earths Water Tip: Keep a spray bottle filled with filtered water on your vanity for a refreshing mist or a water filter jug that you can use for a final rinse after your skincare routine.

Enjoy a More Relaxing Bath

Tap water can contain chlorine, which may dry out your skin or cause irritation especially if you have sensitive skin or eczema.

Using filtered water for your bath creates a gentler experience, takes the edge off, giving your skin a more soothing experience. Think of it as a mini spa session, without the spa price.

Earths Water Tip: Filter your shower water with our Premium Shower Filter especially if you regularly bathe young kids or during flare-ups or colder months when skin tends to be more reactive.

Healthier Aquariums

Aquarium lovers, take note: your fish and aquatic plants aren’t fans of chlorine. Tap water can contain chemicals and heavy metals that stress aquatic life, affect water balance, or even harm delicate species.

Filtered water provides a safer, more stable environment for aquatic life, helping maintain a healthy tank without adding unnecessary chemicals.

Earths Water Tip: Keep a water filter jug near your tank for regular top-ups and partial water changes. It’s a cleaner option for your underwater pets.

Handwashing Baby Items and Delicates

Baby clothes, cloth nappies, and delicates benefit from filtered water, too. It’s gentler on fabrics and doesn’t leave behind irritating residue caused by hard water—ideal for your little one’s sensitive skin.

Earths Water Tip: If you are using our Under Sink RO Water filter, you can use it to pre-soak clothes in a basin with mild detergent. It’s a little luxury that goes a long way, especially with newborns in the house.

Topping Up Appliances

Steam irons, humidifiers, electric kettles, coffee makers, and even diffusers can all benefit from filtered water. Why? Because minerals in tap water can cause scaling, clogging, or residue build-up, reducing appliance lifespan and making cleaning a pain.

You can help prevent this by using filtered water. Less maintenance, fewer repairs.

Earths Water Tip: Use our water filter jug or glass carafe to top up your appliance. No limescale, no weird smells, and no fuss when it’s time to clean.

Cleaning Windows, Mirrors, and Surfaces

Using filtered water when cleaning mirrors or glass surfaces helps avoid streaks and water spots caused by hard water.

Filtered water, especially when paired with a natural cleaner like vinegar, results in a clearer, streak-free finish. It’s also helpful for rinsing surfaces in the kitchen or bathroom where water quality matters.

Earths Water Tip: Fill a reusable spray bottle with filtered water and a splash of vinegar for a simple, effective cleaner. You can also use our Water Ionizer which allows you to customise your water’s PH specifically for cleaning (pH 9.0 to 11.2)

DIY Sprays and Solutions

If you make your own cleaning products, room sprays, or skincare mists at home, starting with filtered water is key. Tap water can introduce impurities or affect the shelf life of your homemade products.

Using filtered water ensures you’re not diluting your formulas with unwanted extras, especially for water-based sprays that are more prone to bacteria build-up.

Earths Water Tip: Use water from our Glass Benchtop Water Filter for DIY cleaners, linen sprays, or face mists. It’s safer, cleaner, and better for your skin and home.

More Than Just a Kitchen Staple

Turns out, filtered water at home is the quiet little upgrade that makes everything else feel better in your everyday routine. From giving your skin a gentler rinse, helping your plants perk up, or keeping your kettle free from limescale, these unexpected uses of filtered water make a real difference without demanding too much effort.

It’s one of those simple swaps that just works: cleaner, better water supporting everything from your morning brew to your pup’s water bowl. Every drop is more than you think.
