What Is Hard Water?

Hard water is a type of water that contains moderate-to-high levels of calcium and magnesium.

We measure water hardness in grains per gallon (GPG) and milligrams per liter (mg/L), equivalent to parts per million (PPM).

1 GPG = 17.1 mg/L OR 17.1 PPM

Measuring Hard Water

A home test kit is an affordable and quick way to measure water hardness.

Hard water isn’t dangerous, so it isn’t essential to know exactly how soft or hard your water is. We advise using a home test kit to know if you have hard water.

But, if you are in trouble deciding between a salt-based and saltless water softener system for your apartment, you should have a laboratory test of your water hardness.

Lab tests give you a detailed, accurate insight into calcium and magnesium concentrations in your water.

Through this, you can select the best softener option for your apartment.

Given table shows the water hardness level:

Degree of hardnessCalcium carbonate: Milligrams per literCalcium carbonate: Grains per gallon
Soft0 – 600 – 3.5
Moderately hard60 – 1203.5 – 7
Hard120-1807 – 10.5
Very hardMore than 180More than 10.5

Common Hard Water Issues

When your apartment has a hard water issue, you may have noticed:

  • Spotting on your cutlery or glassware
  • Leaking or damaged appliances or plumbing, the water doesn’t lather well with shampoo, soap, or dish soap.
  • Mineral-rich water taste
  • Limescale – a white or gray remains- on your sinks, coffeemaker, faucets, showerheads, and bathtubs
  • Stiff laundry with white marks or spots
  • Itchy, dry skin or hair

What Is an Apartment Water Softener?

The apartment softener is a system that’s appropriate for an apartment or a rental property.

They are compact, easy to install, and low hassle to maintain.

The softener needs small spaces to fit and doesn’t require a permanent installation, so it is the right option for a rental house.

How Does an Apartment Water Softener Work?

An apartment water softener removes magnesium and calcium to prevent scale build-up.

This makes the regular water less acidic, improving your skin’s health and brushing your teeth easier. It can also reduce the amount of soap you need, saving you time and money.

Portable water softeners use ion exchange to add salt to the water and remove calcium and magnesium.

How to deal with hard water if you live in apartments?

There are different ways to handle hard water. Some of them are listed below:

1. Use washing soda to do laundry

Washing soda is popular to treat hard water for laundry purposes.

It contains carbonic acid salt (sodium carbonate) that can soften both permanent and temporary hard water.

By removing these mineral ions, hard water becomes more softened.

2. Distilled white vinegar can remove hard water stains

Using Vinegar to Get Rid of hard water stains

Calcium has a pH level of 7+, while white distilled vinegar has a pH level of about 2.5, which is very acidic.

So, the use of vinegar can neutralize the calcium from hard water.

Don’t add too much vinegar to drinking water; it is only adequate for cleaning.

You can also use vinegar spray on household appliances to remove spots left by soap and hard water.

3. Use a magnetic water conditioner

Magnetic water softeners are ideal for tiny areas where a pipe can work with them.

It does not require maintenance, and no need to purchase a new pipeline or cut the old one to install it.

Some softener models require wiring to be connected and do not remove hard minerals from the water.

The softeners use negative and positive strips, which effectively counteract hard water’s effects.

Furthermore, ions that are soluble in water will be present, and several positive and negative charges of minerals will remain in your water.

The magnetic water softener is ideal and most affordable because it does not require an electrical connection.

4. Boiling the hard water

When you boil the water, the high temperature precipitates the calcium bicarbonate minerals.

After removing this hard content, the water becomes clean and softer.

It is a quick and cheaper way to soften the water you consume.

Please Note that boiling only solves temporary water hardness.

5. Use cleaning acid or solutions to remove the soap scum

The calcium and magnesium react with soap’s chemical contents and leave behind soap scum, which can cause a white build-up on all surfaces.

The calcium atoms cause soap scum by preventing soap molecules from dissolving completely. Then, undissolved soap molecules attach themselves to surfaces.

You can use a cleaning acid or solutions to counter calcium atoms.

6. Install a faucet water softener

faucet water softener

A point-of-use softener is the most optimum way to soften tap water. Installation under the sink or onto a faucet will remain low cost.

The two types of compact water softeners are Sodium and Potassium Chloride.

A. Salt-based water softeners

A salt based water softener is a device that uses sodium chloride as one of its main ingredients to soften hard water.

The salt based water softener uses ion exchange.

The exchange of ions is almost immediate while the water flows through the softener.

The chamber traps minerals that make the water hard and immediately change the water quality.

B. Salt-Free Water Softeners

Salt-Free Water Softeners use saltless filtration technology to remove hard water minerals.

They are often recommended for people with allergies or sensitivities to sodium or softening ingredients, such as calcium, magnesium, and potassium.

Salt-free water softeners can also be used in tiny homes, RVs, and Boats.

The Advantages of Owning a Compact Water Softener

There are various advantages of using an apartment water softener:

  1. It helps prevent the build-up of scale or limescale on the surfaces of fixtures and pipes.
  2. The softener makes cleaning dishes, utensils, and other surfaces easier since the soap can more easily produce suds.
  3. It helps extend the life of appliances since they don’t have to work as hard to heat the water.
  4. The softener system also helps in reducing the occurrence of skin irritations.
  5. It improves the water quality for bathing, laundry, and other household uses.
  6. The conventional water softeners are our whole home water system; you can get soft water in your all faucet.
  7. It improves the taste of water.
  8. Soft water helps the hair be shiny and healthy.

How Many Types Of Water Softeners Are Available?

1. Salt-Based Water Softeners

Salt-based water softeners are the most common type of compact water softener.

They work by exchanging hard water minerals for potassium or sodium ions.

The salt-based softeners use a brine tank to dissolve the salt and regenerate the resin beads.

It improves the performance and life of your home water appliances like a washing machine, dishwasher, and water heater and reduces hard water problems.

2. Saltless Water Softeners

Saltless water treatment systems are also a common type of portable water softener. They work by an electronic process that sends a small electrical current through the water.

This current causes the hard minerals to clump together and fall out of suspension.

The saltless softeners do not use a brine tank and do not require salt.

3. Magnetic Water Softeners

Magnetic water softeners are newer softeners, and they work by passing a magnetic field through the water.

This field alters the molecular structure of the hard water minerals, making them unable to attach to surfaces.

The magnetic water softener does not use a brine tank and does not require salt.

4. Gravity Water Softeners

Gravity water softener

Gravity softeners are water softener that uses simple physics to soften the water.

They pass the hard water through a filter containing resin beads. The beads attract and bind to the hard water’s heavy minerals, softening the water.

Gravity water softeners do not use a brine tank and do not require salt.

5. Dual Tank Water Softeners

Dual tank softeners are a type of salt-based water softener. They have two tanks, one for softened water and one for brine.

This allows the softener to run continuously without regenerating the resin beads.

The dual tank water softener system does require salt.

Thinks Before Purchasing A Water Softening Unit?


If you are like many homeowners, you may be considering purchasing a water softening unit. If so, it is essential to think about the unit’s capacity.

Water softening units come in various sizes, and selecting one appropriate for your needs is essential.

Suppose you have a small home or a limited budget. In that case, you may consider purchasing a unit with a lower capacity.

Available Area

Another thing to consider is the area in which you will use the unit.

If you have a large home, you will need a unit with a larger capacity.

Conversely, if you have a small home, you may want to consider purchasing a unit with a smaller capacity.

It should be simple to set up.

When purchasing a water softening unit, it is crucial to ensure it is simple to set up.

You don’t want to purchase a unit that is difficult to install. Effortless water softeners are a great option, as they are easy to set up and use.

Determine the level of hardness

You need to determine your water hardness level, which will help you select a suitable unit for your needs.

If you have a high hardness level in your water supply, you will need a unit with a higher capacity.

If you have a low level of hardness, you may be able to purchase a unit with a lower capacity.

As the given list show, the hardness level:

Degree of hardnessCalcium carbonate: Milligrams per literCalcium carbonate: Grains per gallon
Soft0 – 600 – 3.5
Moderately hard60 – 1203.5 – 7
Hard120-1807 – 10.5
Very hardMore than 180More than 10.5

NOTE: – When you have water hardness in MGL or PPM, you can convert it into GPG by dividing 17.1.

For Example, 170PPM of hardness equals 9.9 grains per gallon of hardness.

And with iron presence, you need to add 5GPG for 1PPM of iron when choosing the softener size.

For Example: If you have 17GPG with 3PPM of iron. You need to select 32GPG sized system.

3PPM of iron X5=15GPG of hardness + 17GPG = 32GPG. (swipe right to see all of the information).
