What is a Portable Water Softener?

A portable softener is a compact water treatment system for a mobile home that reduce the water’s hardness.

The unit uses 50-100 gallons (200-400 liters) of circulated water per regeneration.

Their patented design is based on a conventional softener. Still, it uses a self-contained reservoir filled with brine solution for desalinization.

The softener uses a timer to control the quick regeneration time, which flushes out concentrated brine and restores softness.

They are perfect for homes, RVs, or temporary relocation situations.

The unit will soften water up to 50 grains per gallon a day, depending on the degree of hardness and amount of softer water.

Types of Portable Water Softeners

Ion Exchange softener

Ion exchange or salt-based water softener brands removes calcium and magnesium ions from hard water through an ion-exchange process.

The latest technology learns your water usage patterns to optimize salt and conserve water and energy for you.

The electronic water softener exchanges the calcium and magnesium (Mg) ions in hard water for sodium (Na) ions through an ion-exchange resin bed.

Then, the hard minerals attach to the resin through ionic attraction. The sodium ions are exchanged for these mineral deposits by displacement.

The water then passes through a selective membrane that blocks sodium while allowing calcium and magnesium to continue with the water flow.

It provides softened water for about 18 to 24 cents per 1000 gallons.

Salt-free water softener:

The Salt-free water softener unit is a device to soften water without salt.

It adds calcium and magnesium ions to the water through an ion-exchange process at point-of-use.

The calcium and magnesium ions in hard water precipitate as scale, leaving soft water behind.

Note: This device only functions properly if the feedwater is already “hard,” generally meaning it contains at least 100 ppm (mg/L) of calcium and magnesium ions.

The Salt-free Water Softener consists of a cation exchange resin bed in which calcium and magnesium ions in the water exchange for sodium mineral ions (table salt).

The calcium and magnesium in the softened water precipitate out as scale, leaving soft water behind.

Magnetic Descalers softener:

The magnetic water softener promises to solve your hard water problems without adding chemicals, salt, or potassium.

The makers claim that the inside of the Magnetic Descaler contains hundreds of thousands of tiny magnetic particles.

It works to clean the hard water, which then flows through your home appliances and plumbing fixtures.

The Magnetic Descaler claims to soften your water by replacing the large calcium particles with tiny magnetic particles that your appliances do not detect.

According to the article, a few “hundred dollars” worth of use will last up to 7 years.

Reverse Osmosis system

Reverse osmosis is a technique used to purify water by increasing its purity.

It uses pressure to force pure water through a semi-permeable material that retains impurities.

The RO can remove contaminants from water when ordinary distillation, deionization, and activated carbon filtration are not feasible.

It has a few different water treatment stages, depending on the intended use of the produced water.

A reverse osmosis system is a suitable purification method because it can remove up to 99% of specific contaminants from water.

It includes the most level of mineral content ions and molecules, as well as larger particles.

What to Look for When Buying Water Softener for Mobile Home?

Water hardness level

Before buying a magnetic water softener for a home, you must know the water hardness level.

The hard mineral level is either high or low and affects the tap water.


Hard water needs to be softened, while low water hardness has no effects.

Before selecting a water softening system type and compact size, you must know the hardness level.


Before buying a softener for a mobile home, you need to know what type of system would match your needs.

The type of system depends on the hardness level of water, size of the home, and general needs.

Types include Salt-free and salt-based systems and manual and automatic regenerated systems.

You need to know how much water your family uses, the hardness level of water used in the home, and general needs.


The softener’s size depends on your water usage and its hardness level.

The home size determines how many gallons of water are used daily.

To select the best size for your home, collect all details about the size of your home, its average water usage per day or month, and the hardness level of water.

Grain Capacity

Grain capacity is defined as “the number of water heaters that it can soften.”

The best grain capacity for a softener depends on the hardness level of water.

If the water hardness is high, buy a system with higher grain capacity and vice versa.

Before buying a Softener for your RV and mobile home, it is essential to know the grain softening capacity of your water system.

Built-in features

Some Softeners of homes come with built-in features such as:

Salt level indicator: This shows you when to refill salt.

Softener Bypass valve: This allows water flow even when the system regenerates. Manufacturers use a separate piece bypass valve for additional safety.

Drain cleaning filter: Keeps your drain clean and prevents clogging.

Maintenance port: Helps you to maintain the system quickly.

These features are beneficial, but you must check your system specifications before buying.

Flow rate

Flow rate is the amount of water your system can deliver in a minute.

When buying a Softener for a mobile home, you need to check your softener’s flow rate.

If you have high water usage, you will need a system with a higher flow rate and vice versa.

Please select the best product from the list of the best softeners as per your budget and size.

Installation & Maintenance

If you are planning to get a perfect Softener for your home, you need to find out if the system is easy to install or not.

If it is easy to install, you will have an easier time maintaining it.

You also need to know about the system’s maintenance needs to choose between salt-based or salt-free methods.

Salt-based water softeners need more maintenance than salt-free systems. Salt is the main ingredient of salt-based water softeners.

If you are uncomfortable with the maintenance, go for a salt-free system.

What size softener should I get for my mobile home?

To decide which size of the softener you need, you should find out how much your household uses.

And then, you can choose from various capacities to find the one that matches your water use.

To determine how much water you typically consume, look at your past months’ water bills.

Many home softener brands range from about 1,300 to 8,000 grains. It is a good choice for a family of three to five people.

If you have a family of four, a 5,000-grain capacity is a standard size that can be used efficiently if the water is not too hard.

In this case, a 7,000-grain water softener is the best option for you.

If you have a family of five or more people, you should consider getting a 10,000-grains softener.

Like the 7,000-grain capacity, this type also has outstanding performance and is considered the best.

Where to install a softener in a mobile home?

When you have a home or RV, find space for a softener

 can be challenging.

To avoid finding the right place to put your unit, you might be interested in buying a portable RV water softener.

If you wonder where to install a softener system in a home, here is a quick rundown of some available options.

No matter what softener you have, if it is a traditional style, you will need to choose between in-line under-the-counter for softener installation.

For in-line, you would place the unit directly after your meter. You should install at least a ¾-inch drain line on the team.

It should also be 5-10 feet from your main water line.

You can also install your unit under the counter, as long as you have about 3 inches of vertical space where you plan to install your unit.

A traditional water softener installation will require a bit of work and a little bit of money.

If you’re not up to the task, consider buying a portable RV softener.

How big of a water softener system do I need?

If you have an existing well, this will be easy to determine if you already know how much water you use daily and how many people live in your mobile home.

The easiest way to determine how much water you use each day is to measure the amount of water used by all appliances over 24 hours.

That should give you a good indication as to what size water softener you can afford.

It’s also a good idea to get a few estimates from plumbers before deciding what type and size you want.

Be prepared to pay more than $50 monthly for installation and service after installing the unit.

Can I install a water softener myself?

Yes! If you are handy with tools, have basic plumbing skills, and know-how to work around pipes and fittings, installing a small water softening system may not be difficult.

You will need PVC pipe (or other material that has been cut into pieces), some piping elbows, plastic tubing, valves, and possibly a filter or 2.

For sizing the system, it’s best to call a professional who knows what they are doing.

They will help you choose the correct equipment size and advise on installation techniques.

What are the disadvantages of a water softener?

  • The main disadvantage is that it adds chemicals to your water, which can cause problems for people with certain medical conditions (e.g., kidney disease).
  • They do not always provide 100% removal of minerals.
  • It also requires regular maintenance and replacement of filters.
  • Water softeners tend to be more expensive than other methods of treating water.
  • They may require additional plumbing work in your home.
  • Some models are noisy.
  • They can be challenging to install correctly and very heavy.
  • They can be difficult and time-consuming to maintain.

What happens if a water softener is too big?

The biggest problem with an extensive water softener system is the cost.

A very large unit takes up a lot of space and requires a lot of power to run.

Most often, these units are oversized because they were purchased with the intent to sell them later.

If you decide to go ahead with the purchase, make sure you have room for it and plan accordingly.

Otherwise, it could be a real pain to move.


It is essential to get the perfect water softener for home or RV. It will make your life easier.

When deciding which one to buy, consider the amount of water your household generally uses, the cost of softener you are willing to spend on, and the ease of installation.

And once you have decided on the type of water softener for your mobile home, it is time to look for a good deal.
