Small things can be pretty smart. Water Boss intends to provide such items. The Model 74011 little water softener from the company demonstrates that even the smallest device can operate as well as larger systems.

A built-in water filtration system is housed within the tiny shell of this water softener. It has the potential to reduce the amount of iron in the water. This helps to keep your steel water fittings from rusting.

The device also has water treatment technology that removes various contaminants from the water. So not only do you get soft water, but you also get safe and clean water to drink.

The Water Boss 74011’s ultra-fine resin offers more effective water softening. During regeneration, it consumes less water and salt. Special water softener salts, such as cubes, pellets, or crystal salts, are also required for this product. Regrettably, common table salt cannot be used to regenerate the gadget.

You also don’t have to wait that long for the regeneration cycle to be completed. It only takes 17 to 19 minutes to recharge the system and offers you access to fresh, pure water.

The Water Boss 74011 operates quietly, which I appreciate. While it is not silent, it hums much more softly than other systems. As a result, it is the best water softener for small and cramped living spaces.

As a result, showering is more enjoyable. It’s a piece of cake to wash your garments. The hard water marks and stains on your vehicle and the kitchen sink, tiles, and bathtub have vanished.

This water softener for tiny dwellings that needs no salt is its best feature. While other devices require custom water softener salt formulations, this type recharges the system with just a few pounds of regular table salt.

The Flow-4 Pur’s GPM rating may appear insufficient. You will, however, be relieved to know that the flow is steady. Never again will you be concerned about not having a good time in the shower.

The RV-Pro also includes a cradle base, which helps. The device may be easily secured to practically any surface, thanks to the base. It never sags in its position.

Some consumers complain about the narrow diameter of the canister’s entrance, which makes it challenging to pour table salt for regeneration.

One possibility I see is to use a funnel to reduce salt waste. Another minor flaw in the design is the inlet hose connector, which does not rotate. To connect the system, you must twist the hose itself.

The Flow-Pur RV-modest Pro’s price makes it excellent for tiny and budget-conscious houses. In addition, the device softens water in the same way traditional water softeners do. As a result, it does not necessitate any more space.

A better economy results from less frequent regeneration. It is also never an issue to regenerate the PRO+AQUA. To replenish the system, use regular table salt. In five minutes, you’ll have your water ready.

I can see why car detailers adore the PRO+AQUA. It has an admirable water flow rate, making it ideal for portable power washers. Its 5-gallon-per-minute flow rate is adequate for washing your car, your house’s walls, and even your garage.

Is it possible to install a water softener in an apartment?

Depending on the size and location, this is highly conceivable. It can be for the entire house or a specific location. Most of the water softeners discussed in this piece will fit into any apartment, no matter how small.

Water softeners were created to combat the hard water problem by removing minerals such as calcium and magnesium, among others. This will keep white deposits from collecting in your kitchen dishes and faucets and help your soap develop a good lather. The entire procedure is known as reverse osmosis.

Let’s look at a couple of water softeners that will perform nicely for your flat without breaking the bank. They’ve been tried and trusted to get the job done right.

Why do I need a water softener for my apartment?

A water softener is a gadget that many families worldwide might benefit from. It all boils down to the type of water a household consumes. Municipal water sources generally contain several minerals that cause water to be “hard.”

This water has a high concentration of dissolved calcium, magnesium, iron, and various other particles.

So what is the drawback of hard water? This causes many home annoyances and, in some cases, infections. As a result, hard water needs more frequent and comprehensive maintenance of your faucets and pipelines. We’ll now look at some of the most common issues produced by hard water.

  • Traces on your dishes and faucets — There will undoubtedly be soap scum on your dishes and bathroom fittings. If you allow the water to dry on any surface, it will leave a foggy film behind. Essentially, every customer researching water softeners in 2021 will attest to this being one of the primary difficulties with hard water.
  • Your skin will feel it as well – because some unpleasant substance is left behind on surfaces, hard water will make your skin feel drier and itchier. All of this can be avoided with soft water.
  • There will be buildup in your pipes – mineral compounds in water are the primary cause of limescale buildup inside your pipes or showerheads. You might also be interested in our reviews of shower filters for hard water and our blog post on water softener showerheads. This also applies to appliances that are susceptible to rough water. This buildup causes considerable damage to your home’s entire water-related infrastructure.
  • Water heaters are also in jeopardy, as hard water is one of the leading reasons for heating element inefficiency in tankless water heaters. Not to mention that it may cause significant harm to many components if not properly maintained regularly.
  • Corrosion and rust are other possibilities.
  • Soap and shampoo are less foamy — hard water can drastically reduce the lather of all hygiene products. As a result, they will be less effective and produce less foam. That is not a good sign.
  • Laundry will not be as visually appealing, and items will feel stiffer after being washed in rough water. They will be less vivid, and you may notice yellowish patches on them.

So, now that we’ve covered all of the aforementioned hard water difficulties let’s look at how a softener can help eliminate them. But, before we get into the specifics, let’s go over the primary advantages of water softening.

How did we evaluate the water softeners for apartments?

You’re mistaken if you think we just included water softeners for flats based on the brand! There was much to think about while listening to the water softeners from various brands.

Water softeners with good ratings and evaluations for efficient operation can be found in our guide. But, in truth, we tested the water softeners and included the alternatives that provide the most value for the money.

So, if you want to get rid of persistent stains on your bathroom, kitchen appliances, pipes, and other surfaces quickly, it’s time to invest in one.

We understand how inconvenient it may be when hard water stains do not leave your appliances and begin to irritate your skin. Because you’ll need more body washes, detergents, and other washing agents due to the hard water, your bills will rise. In addition, after only one wash, your clothes will appear dull.

Fortunately, the most excellent water softeners are currently available from numerous businesses on the market.

What you should know about water softener for your apartment

Whole-house water softeners are frequently the solution to hard water problems; however, due to how most apartment buildings are plumbed, a typical water softener is not the solution for most apartment inhabitants.

Installing a point-of-entry water softening system is unlikely to be permitted or practicable. Even if you have permission from your landlord to install it, the costly system will undoubtedly become his property if you depart.

If hard water bothers you, it’s undoubtedly bothering your neighbors in the apartment complex and the landlord. Service calls for appliance repairs and plumbing issues can be costly for the building owner; likely, your landlord will eventually recognize the benefits of investing in a POE system for the entire building.

On the other hand, if your landlord isn’t convinced and you’re tired of living with hard water, you may easily change the quality of the water in your own home.

Water treatment at the point of use vs. at the point of entry

If you rent your home and wish to improve your water quality with a water filtration system, you should understand the difference between point of use (POU) and point of entry (POE) techniques. POE systems are put right where the water enters your home.

They are also known as whole-house water treatment systems since they treat all water that enters the household. However, this form of filtration is installed at the main water line. It may be impractical to install if you live in an apartment or condo since the connection required to install is challenging to find and requires authorization from the landlord.

A POU water treatment device is exactly what it sounds like: it is put at the point of use and connects directly to a faucet or shower, purifying only the water that comes from that source. These systems, like a POE, can provide high-quality, great-tasting water by eliminating contaminants.

A point-of-use water purification system is the easiest to install if you live in an apartment or condo. Smaller, more compact systems can readily fit into closets beneath sinks, mobile homes, or apartments, where space is often limited.

Naturally, the size of a water filtration system is a consideration when evaluating the available space. POU water softeners are compact and straightforward to install at a single water connection, usually beneath the sink of your kitchen or bathroom, and treat the portion of the water you use for cleaning, bathing, or drinking. The small amount of room you give up for a filtration system is well worth the outcomes. Your water will be odor-free, delicious, and free of limescale, hard water, and rust stains.

Buying a water softener for an apartment

Some crucial elements to consider when purchasing a water softening machine are as follows.

Their small size

The first and most crucial aspect to look for in a compact softener is the level of compactness they provide.

First, measure the space where you want to place the water softening, and then hunt for a softener that meets the compactness standards.

Bring home any softener even an inch more significant than the one installed, as it will only give you more problems.

It should be simple to set up.

When selecting a compact softener, choose one that does not require additional installation.

Installing a softener in a tiny location can be challenging and stressful because no one wants to stand in a crowded area for 5 to 6 hours. As a result, a softener that can be installed in a matter of minutes is preferable.

Determine the level of hardness.

The first and most important thing to remember when buying a water softener is to assess the water hardness level in your location. If you haven’t done so, you’ll never know how many grains you’ll need to soften your water.

As a result, you will bring the incorrect product with limited grain capacity, which will not be able to soften the water to its fullest extent.

Consider your requirements.

Another item to consider is what you genuinely require. For example, is your water merely hard, or do you have other difficulties, such as pollutants and sediments? Because if there are, you should not rely just on a water softener to fix your problem.

In this situation, you will need to purchase a water filter. However, purchasing both can be costly, so consider a 2-in-1 water filter and softener. It will remove any impurities while also removing hardness.


Select the softening capability of the water softener. To treat hard water, select a water softener with the appropriate water flow capacity. You’ll also get a water softener with a capacity of 0.002 oz. So, for example, three types of hard water might determine its power.

You can set the water hardness level to anything between 0 and 7.5 liters of hard water.

  • The soft water will have a gpg of 0 to 3.
  • Water with a medium hardness level contains 3.5 to 7 up.
  • Hard water is defined as less than 7.5 gpg or up to 7 gpg, and you must install a water softener in your home.

In addition, the capacity of the water softener will necessitate a measurement of how many grains are required to soften the hard water. On the other hand, the small water softener will have a capacity ranging from 16000 to 32000. In addition, water softeners in smaller sizes will be available, making them ideal for RVs, condos, and other tiny spaces.

Water softeners with grain capacities ranging from 40000 to 64000, on the other hand, are ideal for medium-sized homes. Furthermore, large homes should have a grain capacity of 80000 to 10000, which is the most appropriate.

Remember that the water will only be treated if you have the appropriate softening grain capacity. Nothing will change if you install a tiny water softener with the highest hardness setting.

The available area

The most crucial consideration when purchasing a water softener is the available space. First, you must select a water softener based on the size of your home, whether it is salt-based, salt-free, or has a dual tank. Next, you must choose a water softener appropriate for that location. For example, after reviewing the installation specifications, you should select a water softener.

In this guide, you can find water softeners that are ideal for medium and small households. In our evaluation, you can find a wide range of water softeners. Furthermore, certain water softeners can be installed directly on the home pipelines in either the vertical or horizontal direction. At the same time, some require the water line to be hung for one to two feet, depending on the brand. You must choose a water softener style that is appropriate for the size of your home.

On the other hand, salt-free water softeners will be the most portable solution. Furthermore, the portable water softener is an alternative option to our article’s massive salt-based water softening systems.

Furthermore, you should only install a salt-based water softener in your home when the hardness level is at its highest. Furthermore, substantial salt-based water softeners require extensive maintenance and are not designed for RVs or flats.

You should go with magnetic water softeners because they take up less space and require less maintenance. It will also not take up much space or require much alteration, and you can quickly correct it with your pipeline. Best of all, it won’t take up any floor space. We strongly advise putting descalers in flats and RVs because it will be both efficient and helpful.

The flow rate of water

The amount of water that travels through the ion exchange resin over time is another element to consider when purchasing a small water softener. The optimum water softener should deliver the same water flow rate as your home’s water line.

If your water flow rate is five gallons per minute, you should choose a device with the same flow rate. A 3 GPM unit will lower the amount of water from your faucet and other water faucets.

You must also consider how many others will be using water simultaneously. A 3-GPM device is frequently sufficient for a two or three-person household. However, this unit might not be enough for a household of five. This is true if everyone uses water at the same time.

The bypass valve

The bypass valve of the water softener will function properly. You will have a pipe that can close and open and function exactly like a typical valve.

Furthermore, you must install the water softener with the valve because it will deliver water while also regenerating it. Additionally, the bypass valve will operate as a water diverter. Therefore, you can quickly restore direct water access from that valve.

However, if your water softener lacks a valve, you may consider it useless. Aside from that, a bypass valve is required to conserve your all while limiting excessive regeneration. You must avoid wasting both water and salt.

With the bypass valve, you can easily divert the flow of water. As a result, you will have the most straightforward choice to prevent non-softened water from entering your home’s pipes. But, first, you must restore the flow and valve by adequately installing and repositioning the water softener.

Cycles of regeneration

The regeneration cycles are the final feature. You must track how often the water softener recycles the water. You can only verify the regeneration if you know you have a metered system, and it will also have a timed system.

1. Water softeners with metering

Metered water softeners are included with the counter. You will know how many grains are needed to soften the water. Furthermore, the regeneration will be automatic, and you will have the most acceptable choice to stop it when you are not at home. It will be the most excellent alternative to pause regeneration when you are not home or on vacation to save the salt grains.

2. Water softeners with timers

The scheduled water softeners will replenish the water automatically, and you can set the timing. More grains will be used in this softening unit to soften the water. The regeneration levels will also be limited. Aside from that, water softeners with longer intervals will not soften the water perfectly.

Use of salt

Salt-based water softeners are the most efficient. There are also salt-free water softeners available. However, they are not actual water softeners because they do not remove the minerals that hardness water. We refer to these systems as water conditioners instead.

Regeneration of water softeners necessitates the use of salts. As a result, you should monitor the amount of salt required by the system every time it needs to regenerate.

Compare this to the system’s grain capacity. A limited grain capacity system will necessitate more frequent resin regeneration.

You should also examine the type of salt required by the system. For example, some products use regular table salt, while others use specialist salts designed for water softeners.

The prefilled high-charged resin must be present.

A highly charged premium quality resin must be present in your softener. Never compromise on resin quality since the removal of all ions and metals depends on the softener’s standard and quality.

Examine your budget

The most important thing to remember is always to keep a close eye on your money. Don’t go for something out of your price range because it will exacerbate your troubles.

So, if you’re on a tight budget but need a water softener, you should choose a softener with only one feature: softening the water.

You should not consider other features such as digital controls, designs, styles, facilities, etc., because a softener with these characteristics will cost you hundreds of dollars.

How to install a water softener

The advantage of all home filtration systems is that their installation is essentially the same. Learning how to properly install a water softener, on the other hand, can be a difficult undertaking, and if you are unsure, you are better off hiring an expert. In any case, for optimum clarity, we will walk you through the essential steps of the procedure.

  • Turn off the main water supply and look for the inlet line inside your garage or basement.
  • Cut the pipes after your water meter before entering your home.
  • This is where you want to connect your pipe – it should have three valves: one to prevent water from entering the softener, one to prevent water from departing the softener, and one bypass valve.
  • Check that the connectors are securely in place and, if necessary, undertake some soldering.
  • Connect the media tank to the brine tank via 3/8 plastic tubing (typically included).
  • Connect the drain line to the drain elbow using a hose clamp.
  • Connect the wastewater drain to the discharge pipe.

Frequently Asked Questions (FAQs)

What should be the regeneration time of a water softener?

Water softeners typically renew multiple times per day. After 80 minutes, most of the compact water softeners on our list will regenerate. The optimal regeneration period for all water softening systems is 80 to 85 minutes.

How do portable water softening devices work?

The water softening device contains resin beads that reduce the hardness of the water. The complex ions are extracted from the water as it travels through the resin tank. The majority of water softeners remove calcium and magnesium ions from hard water.

Is it required to clean the brine tank of a water softener?

No, the brine tank does not need to be cleaned. However, if you find any pollutants in the brine tank, you must wait until the salt in the brine tank runs out. Aside from that, you can clean a brine tank after removing all the salt.

When is it necessary to add salt to a water softener?

The latest water softeners do not require a large amount of salt. However, after six weeks, you must add salt to a water softener. Aside from that, you should check to see if the water softening is operating correctly after six weeks.

What is the best way to clean a water softener?

To clean a water softener, empty the tank of all water and salt and dispose of them. The brine grid should then be removed from the tank’s base and left aside. Next, scrub the tank’s interior with warm, soapy water and a long-handled brush before rinsing with plain water.

After rinsing, fill the tank with 1/4 cup of household bleach and 2 to 3 gallons of water. To destroy any bacteria, allow this mixture to settle for at least 15 minutes. Next, re-rinse the reservoir, reinstall the brine grid, refill with water, and replenish with salt.

Is drinking water from a water softener safe?

If the only contaminants are hardening minerals, drinking water from a water softener is harmless. This is because the water softener will eliminate or neutralize the hardening minerals, preventing them from combining. On the other hand, a water softener is not a water filter and will not remove any other dangerous particles. As a result, it should only be used to soften water and not to cleanse it.

Is soft water harmful to copper pipes?

Mineral-free water is referred to as soft water. Because of this, it will pull minerals from unlined metal pipes, such as copper, and can produce pinhole leaks over time.

When hard water passes through a softener, it produces softened water. Softened water originally contained a high concentration of minerals and has been returned to a neutral state. As a result, it has no need for or desire for minerals. As a result, it is entirely safe for your pipes.

Does a compact water softener remove sulfur?

Water softeners, in general, do not remove sulfur, but those with a two-in-one quality water softener and filter can also remove sediments.

How frequently should you regenerate?

The regeneration process is recommended to be repeated every 7 to 11 GPG.

Is it possible to use a compact water softener for a large family?

No, a compact water softener is designed for apartments and families. They do not have enough grain or water capacity to meet the needs of larger households.

How many people can be reliant on a little water softener?

In general, an average compact water softener is sufficient to meet a family’s water needs.


After reading all the top water softener features, you will undoubtedly be able to select one for your apartment. The flat will have no hard water problems once you have installed the water softener. For example, there will be no stains on the faucets or clothes.

What’s the good news? After installing these water softeners, we investigated and discovered that soap and detergent produce more excellent lather. However, selecting a water softening device is critical based on the hardness level of the water in your apartment.

We promise that no matter whatever water softener you purchase, it will eliminate the challenging water problems. Furthermore, before purchasing a water softener, you should consider its features and price.

Overall, all the water softeners for apartments are NSF certified and high-quality.
