Best Marine Water Softeners in Australia (Ultimate Guide And Review)

  • Marine Water Softener – What is it? What does a Water Softener do?

Even though its name might suggest that marine water softener is for boats, that is not the case. A marine water softener is also known as an ‘on the go’ water softener, which means they are portable water softeners. Traditional water softening units are designed for home or stationary use. In comparison, marine water softeners are designed for traveling purposes.

Just like a traditional water softener, a marine water softener also removes hard minerals and metals from the water, making it safe for you to use while you are in your vehicle. Whether you are on land or in the sea, a marine water softener will always provide you with safer and cleaner water no matter where you are traveling.

Just like the traditional water softeners, these ones too remove minerals like calcium, magnesium, iron, zinc, and lime for the water. Hard water causes serious damage to the pipes and plumbing system of the house. Similarly, hard water also causes severe damage to your RVs or boats’ pipes and plumbing system.

This happens because the excess minerals and metals from the hard water begin to form a build-up in pipes and other water appliances. The hard minerals and metals in the water also cause corrosion and a build-up of rust in your car, boat, or home’s plumbing system.

Having a marine water softener in your RV or boat will protect your vehicle’s pipes, plumbing system, and any other water appliances that are there. Your boat, RV, or mobile is saved from the mineral scaling that happens due to hard water. Not to mention, with a marine water softener, you will always have clean water to drink and cook whenever you go. Because consuming hard water by drinking or cooking isn’t too safe either and can cause severe health issues.

One of the main differences between a marine and a traditional softener is that the former has a more compact design. It does not take up much space, and you can conveniently carry it with you wherever you go. The marine softener does not need any electricity or accessories to work its magic. It is designed to carry around and be moved around a lot.

Best Marine water softeners in Australia are ideal for those of us who love to travel and have outdoor adventures often. They are also suitable for those who have mobile homes, RVs, boats, and people who go camping often. And in case of an emergency, these marine softeners are a useful back up for homeowners as well.

Investing in a quality marine water softener is a smart move. Whether you love outdoor adventures or are a homeowner, this system is a practical, smart, and lifesaving investment.

  • How Does A Marine Water Softener Work? 

A marine water softener works similarly to a traditional water softener. However, marine best water softeners in Australia are easier to use than regular water softeners. A regular garden hose works perfectly well for connecting marine water softeners. It’s extremely easy to set-up because the garden hose will easily connect your boat or RV to your dock faucet or local park.

Best Marine water softeners in Australia are charged, pre-assembled, and ready to work their water softening magic. What’s incredible about these systems is that they do not need any electricity or accessories to begin softening the water. And in many cases, you get the connectors with the kit when buying the softener. That said, it is always good and handy to have Teflon tape in your vehicle.

With marine softeners, you can have soft water anywhere you go, and they are compact than traditional softeners. But they work just like traditional softeners do. They remove harmful minerals and metals from the water, making the water safe and healthy t use for cooking, drinking, or for literally any other purpose.

Best Marine water softeners in Australia, just like the traditional softeners, have resin beads that contain salts. When hard water passes through the resin beads, the salts exchange places with ‘hardness ions’ ( ion-exchange process) present in the hard water. The hardness ions then stick to the resin beads where the salts used to be. The salts in the resin beads are now in the water instead of the hardness ions giving you soft water.

To facilitate the ion exchange process, the salts need to be refilled regularly so that the softener can regenerate itself. Some marine softeners regenerate automatically, and others don’t. Depending on which model and brand of marine softener you have, you might need to manually add the salts into the softener so that it can regenerate itself and get ready to soften the next batch of hard water.

The softener needs to regenerate itself because the resin beads attract the hardness ions from the hard water during the ion exchange process. The hardness ions get stick in the resin beads. If the hard minerals and metals are not regularly removed from the resin beads, there won’t be space for the hardness ions that come in with a new batch of hard water. And so, the softener cannot do what it was created to do.

As we said, many softeners regenerate themselves meaning they remove the hardness ions from the resin beads and flush them out of the system. But depending on your model, you might need to manually add salts to the resin beads to remove the hardness ions from there.

So, you won’t be spending more money on buying soaps, shampoos, and detergents as you will be using less of them.


Like with everyone and all products, marine water softeners also have some disadvantages. For example, because these systems use salts as the main ingredient to remove hard minerals and metals from the water, the water can be too salty for some. While some people do not mind the salty taste, others may not find it to their liking. For some, too much sodium may also pose a health risk.

What Do I Need To Consider While Buying Best Marine Water Softeners in Australia?

Hardness Level

Different brands and models of best water softeners in Australia can remove different levels of hardness from the water. If you are expecting to go to a place where the hardness of water is exceptionally high, then investing in one of the high-end marine water softeners is the best.

Grain Capacity

The higher the grain capacity, the cleaner and safer your water will be. Commercial and high-end marine softeners have a solid grain capacity of 15000 grains, so ensure that you’re not settling for less.


Once you buy a marine softener, the next part is about using it and then maintaining it. And how well you maintain it will determine how long the softener will last and how optimally it will perform. So while buying the softener, note down how it needs to be maintained and how often you need to clean, replenish, and maintain it.
