Backed by a lifetime limited warranty and made with NSF certified food-grade premium resin, the water softener is designed to last while making the hard water softer.
  • SAFE FROM HEAVY METALS – Too much exposure to heavy metals can lead to numerous health problems. When regularly exposed to high levels of iron, lead, radium, and other heavy metals, it can cause damage to your immune system, making you more susceptible to illnesses. Protect yourself and your loved ones by using the water softener to drastically reduce your exposure to heavy metals.
  • SAVES YOUR SKIN & HAIR – Hard water can take its toll on your skin and hair. It’s known to contribute to dry skin and worsen different skin conditions, such as eczema while leaving hair looking dry and dull. If you color your hair, the hard water might even strip the color from your strands! The convenient, portable RV water softener will help you protect your skin and hair by softening the water and preventing added exposure to metals like iron and radium.
  • MULTIPLE PURPOSE – Our convenient RV water softener portable device is safe and effective enough to handle various applications.

Use our portable softener as often as you’d like to combat the struggle of dealing with hard water.
  • REMOVES WATER SMELL – Hard water is notorious for smelling like rotten eggs and having a foul taste. Improve the overall smell of the hard water at home by using a water softener. Because the softener prevents scale buildup and reduces the number of metals in the water you use daily for bathing, and washing your hands when they’re dirty, the water will be fresher and without the odor.

How to Choose Water Softeners

Capacity Matters

Choose a water softener based on the number of bathrooms in your home. A good rule is 32,000 grains for 1-2 bathrooms, 40,000 to 48,000 grains for 3-4 bathrooms, and at least 64,000 grains for homes with 4 or more bathrooms. This ensures sufficient softened water supply for your needs.

Regeneration Type

Select between time-based and meter-based regeneration. Time-based systems regenerate at set intervals, while meter-based systems do so based on actual water use. Meter-based systems tend to save salt and water, making them more efficient.

Ease of Installation

Look for water softeners that are easy to install. Some models can be set up without professional help, while others may require plumbing skills. Check product descriptions for installation details to avoid complications.

Maintenance Requirements

Consider the maintenance needs of each model. Some systems require more frequent salt refills than others. A good water softener should have a simple maintenance routine, so you spend less time monitoring it.

Warranty Options

Review warranty options before purchasing. A good water softener often comes with at least a 5-year warranty. This indicates a level of trust from the manufacturer and can save you money on repairs down the line.

Frequently asked questions

What is a good water softener?

A good water softener effectively removes hard minerals like calcium and magnesium from your water supply. It should have the right capacity for your home size and be easy to maintain.

How does a water softener work?

A water softener works by using salt or potassium to remove hard minerals from water. These minerals are exchanged for sodium ions, resulting in softer water.

Why should I use a water softener?

Using a water softener can improve your water quality. Softened water is better for skin and hair, increases the lifespan of appliances, and reduces soap scum.

How often should I add salt to my water softener?

You should check and refill the salt in your water softener every 4-6 weeks. The frequency depends on your water usage and the capacity of your system.

Can I install a water softener myself?

Many water softeners are designed for easy installation and can be set up without professional help. Always check the product manual for specific instructions.

What to look for

Water Hardness Level

Understanding your water hardness level is important. You can test your water using a hardness test kit or get results from your local water supplier. Knowing the hardness helps you choose the right water softener capacity. The higher the hardness, the more capacity you need to efficiently soften your water.

Space Requirements

Consider the space where you will install the water softener. Measure the area to ensure it fits comfortably. Water softeners vary in size, and some require more space for brine tanks. A compact model may be essential for smaller homes or apartments.

Brine Tank Capacity

The brine tank holds salt for the softening process. Choose a model with a brine tank that fits your water usage. Larger tanks require less frequent refilling. This can save you time and effort in maintenance.

Regeneration Frequency

Different models regenerate at varying rates. Some regenerate daily while others may do so weekly or based on usage. Choose a model offering flexibility in regeneration to match your household’s water consumption patterns.

Flow Rate

The flow rate measures how much softened water can be delivered at once. Look for a water softener with a flow rate suitable for your household size. For larger families, a higher flow rate ensures that multiple faucets can be used simultaneously without a drop in water pressure.
