2022 Buyers Guide to the Best Portable Water Softener

How Does A Portable Water Softener Work? 

Getting the most out of your portable water softener purchase means knowing how it removes the hard water minerals and makes your drinking water soft, fresh and pure.

For the best water filtration and softening systems to work at maximum efficiency, they require the best filters, or media, to trap the different size particles of minerals and harmful contaminants as they pass through the water softening system and up into your tap. 

The models use resin bead filtration media firmly packed into the tank. As the hard water passes through the beads, calcium, magnesium, and other harmful minerals and metals, stick to them, like metal to a magnet, and in the process, exchange them for sodium or potassium.

Finally, as the resin beads get covered with sodium ions, they swap places with the calcium and magnesium ions until they contain nothing but calcium and magnesium. At that point, it’s time to change the resin bead media to keep the soft water flowing.

Benefits Of An On The Go Water Softener

With an on the go water softener you can get all the benefits of a whole house softener system, but at a fraction of the cost and with minimal maintenance. Additionally, they are portable water softeners so you can easily move them around. Most of the models even come with handles on top.

Of course, the biggest benefit to your water softener system is that it will allow all of your appliances to last longer, and reduce scale buildup on your water fixtures, while providing soft water for healthier skin.

Types of Portable Water Softeners

Ion Exchange

Household water softeners are ion exchange devices. Ion exchange involves removing calcium and magnesium hardness ions and replacing them with non-hardness ions, typically sodium supplied by dissolved sodium chloride salt or brine.

Salt-Free Conditioners

Saltless water softeners (AKA salt-free conditioners) are instant money savers as you aren’t required to buy, haul and schedule refilling the water softener with salt. Salt-free water softeners use potassium in place of sodium.  Potassium produces chemical transformations during the water softening process. The potassium “sticks” to the hard water deposits during this crystallization process. 

Don’t worry about any potential mineral buildup clinging to your RVs plumbing. The existing water source at the campground laundry, and other surfaces that hard water can develop on scale; the potassium exchange flushes the hard water creating minerals down the drain!

Electronic Descalers

As the name implies, electronic water descalers are a water treatment system that reduces your RV water’s hardness by allowing the water to pass through a magnetic field. 

Using an electronic field created by wires wrapped around the outside of your RV’s plumbing, the force alters the hard water mineral ions as it enters your RV’s plumbing system.

Reverse Osmosis (RO)

Reverse Osmosis is a popular water purification and softening system specifically designed to filter out up to 99.9% of minerals and contaminants found at the water’s source before entering your tap.  RO systems use a semipermeable membrane to remove lead, harmful chemicals, pesticides, and bacteria commonly found in well and municipal water supplies. 

Be cautious when considering an RO filtration system. RO water filters are not hard water-specific, and the filters can wear out quickly when calcium and magnesium particles flush through the system. Consider adding a compatible portable RV water softening system to your existing RO system to preserve the RO system’s life.

Things To Consider Before Purchasing A Portable Water Softener

Cost

You’re not going to break the bank when shopping for a portable RV water softener tank. Be more concerned with the space you have to store the system.  That said, look for thoughtful construction, a fiberglass-wrapped tank, stainless steel or copper connectors, and high-capacity resin bead media. You can expect to pay between $185 – $300.

Type of Portable Water Softener

Before determining the type of portable water softener you want, you need to test your water.  Whether you’re a full-time RVer or a summertime adventurer, all along your route, you want to test the hardness of the water continually. And while you’re at it, check the water for the levels of chemicals, metals, bacteria, and other contaminants.

Your portable water softener is the last tank the water will run through. To be safe and ensure you’re drinking the healthiest water, consider a water filtration system to accompany your water softener. 

Remember, you’re hooking up to many different water sources. Try to get the results from the permanent water source you call home. Conversely, call the municipalities so you can determine the type of portable water softener you need for your journey.

Grain Capacity

If you don’t want pulp in your juice, you push the fruit through the finest mesh sieve. Same goes for your portable water softener. Consider the “pulp” of all the contaminants and hard water causing minerals you don’t want in your drinking water.  Consider the grain capacity of the “fine mesh sieve.” The higher the grain capacity the less volume of water passes through the grains, guaranteeing the best, soft water results. 

The good news is you don’t lose water pressure or experience a lower flow rate. The fine grain resin media is designed especially to allow the hard water to pass through freely while trapping the hard water causing minerals and contaminants. Look for portable RV water softeners using 10,000 – 16,000 grain NSF certified resin.

Installation and Maintenance

Besides the ease of use and ability to soften water safely and economically, the installation of your portable RV water softener equates to connecting a water hose to the tank connector and letting the water flow!

Maintaining your portable RV water softener is easy too. Determine how much water you usually filter, then after 10,000 – 16,000 gallons, you have a fresh batch of resin media. Out with the old, in with the new!

Frequently Asked Questions

Will a portable RV water softener affect my water pressure?

No, most portable RV water softeners can soften 4-6 GPM with a psi of 150. Check your flow rate at the source to determine how many gallons can flow through the resin media. It will determine how efficiently the system works to keep fresh, healthy, and soft water flowing.

How do I store my portable water softener when not in use?

Make sure your portable RV water softener includes some soft silicon cap protectors. When the portable water softener is not in use, protect the tank’s connectors from the elements. It’s best practice to lessen the time you need to back flush the system, and waste potentially good water when it is time to rotate it back into service.

How long does a portable water softener last?

Portable RV water softener tanks can last up to ten years. If the connectors are brass, copper, or stainless steel, you won’t run the risk of unexpected leaks. Just make sure to schedule regular resin media changes to keep the inside of the tank healthy and ready to soften water when you need it.

Final Thoughts on Buying a Portable RV Water Softener

Do you live the RV life? Got itchy skin and mineral stains in your RV shower? How about a cloudy shower door and low water pressure? Hard water is plaguing your RV’s plumbing. The good news is, treating your RV’s water isn’t a costly undertaking.

A portable water softener is easy to install onto your existing water line and plays well with your mobile vacation accommodations.
