Best Compact Water Softener Reviews
1. On The Go OTG4-VM-DBLSOFT Water Softener
The On The Go water softener lets you enjoy the many benefits of softened water, regardless of where you are. So you can lead a life that is free from the effects of hard water.
This compact water softener system performs like standard-sized water softeners, yet it does so in a small package. Plus, its compact design makes it the ideal solution for people living in small homes or apartments. Those living off the grid will also benefit from its portability.
Put the OTG4-VM under the sink or in your cabinet. You can also place it in your RV or camper. The next time you park your vehicle near a public faucet, you will have access to soft water on demand.
The beauty of this product is that it has a simple yet effective design. It does not require special salts to regenerate the system. All you need is your ordinary table salt.
Notably, OTG4-VM only needs your attention every 40 days. Combined with its table salt regeneration requirement, this water softener is one of the most cost-effective solutions you will ever have.
This product can soften water more efficiently than conventional systems. It is about 40 percent more effective than other brands. The OTG4-VM’s efficiency rating translates to better savings. Less salt. Less regeneration frequency. Less hassle. You could never ask for more.
I like the inclusion of a back-flush adapter. Connecting the system to any existing water supply line is easy. It facilitates the more efficient backwashing of the system in preparation for regeneration.
2. WATER BOSS 74011 Water Softener
Small things are smart things. Such products are what Water Boss aims to provide. The company’s Model 74011 small water softener proves that even the most compact device can perform as efficiently as larger systems.
Inside the compact casing of this water softener is a built-in water filtration system. It can reduce the level of iron in the water. This helps protect your steel water fixtures against rust.
The device also features a water treatment technology that removes other substances in the water. What you get is not only soft water but also safe and clean water to drink.
The ultra-fine resin of the Water Boss 74011 ensures more effective softening of your water. It uses less water and less salt during regeneration. This product also requires special water softener salts, such as cubes, pellets, or crystal salts. Too bad you cannot use your ordinary table salt to regenerate the device.
You also do not need to wait that long to complete the regeneration cycle. Seventeen to 19 minutes is all it takes to recharge the system and give you access to fresh and clean water.
I like the quiet operation of the Water Boss 74011. While it is not whisper-quiet, it does hum a lot softer than other systems. This makes it the ideal water softener for small and tight living quarters.
3. Watts Water Flow-Pur RV-Pro Water Softener
Owners of small houses looking for a reliable and compact water softener can put the Watts Water Flow-Pur RV-Pro on their shortlist. This model is a compact system that can fit into almost any space.
The Flow-Pur softens water to protect your water fixtures, pipes, and appliances from corrosion. It draws compounds that make water hard and drains them out of the system.
As a result, shower times are more pleasant. Washing clothes is a breeze. Gone are the hard water spots and stains on your vehicle or even on the kitchen sink, tiles, and bathtub.
The best part about this water softener for small houses is its salt requirement. While most products require unique formulations of water softener salts, this model recharges the system using only a few pounds of ordinary table salt.
The 4 GPM rating of the Flow-Pur may seem insufficient. However, you will be happy to know that the flow is consistent. Never worry about not having a good time in the shower ever again.
It also helps that the RV-Pro has a cradle base. The base makes it easy to secure the device on almost any surface. It never wobbles in its place.
Some customers complain about the small diameter of the canister’s opening, as such a small hole can make it challenging to pour table salt for regeneration.
One solution I see is to use a funnel to minimize wasting the salt. Another minor issue about the design is its inlet hose connector that does not rotate. You will need to twist the hose itself to connect the system.
4. PRO+AQUA Portable RV Water Softener
“Small but as powerful as standard-sized water softeners” is what many people are saying about the PRO+AQUA Portable RV Water Softener. While its main use is on recreational vehicles and boats, the PRO+AQUA can also prove invaluable in small homes.
This small water softener system performs more efficiently than other water softeners of the same size. In truth, the model can provide up to 40 percent more softened water than other competing products.
This system can handle water coming from the municipal or city water plant or even the well in your backyard. It is a great solution for those living off the grid.
Besides, the resin of the water softener has a 16,000-grain rating. If you are judicious in your use, you can enjoy soft water for up to 40 days before recharging the system.
Less frequent regeneration translates to a better economy. Regenerating the PRO+AQUA is also never a problem. You can use ordinary table salt to regenerate the system. You will have your water ready in five minutes.
I can see why automobile detailers love the PRO+AQUA. It has a commendable water flow rate that makes it great for mobile power washers. Its 5-gallon-per-minute flow rate is sufficient for washing the car, the walls of your house, and even your garage.
Installing the PRO+AQUA water softener is easy. However, some customers complain of not getting a perfect seal when connecting the hose to the ports. Improper connection can lead to leaks.
5. Mobile-Soft-Water Portable Water Softener
If you are looking for a water softener for small spaces, I recommend the Mobile-Soft-Water Portable Water Softener. It is a compact system that does not demand plenty of space, thus ideal for recreational vehicles. Plus, it is lighter than other compact systems. Bringing it to your RV or boat should never be an issue.
This powerful device can be a reliable companion for your car wash chores. The unit can handle almost any level of water hardness without sacrificing the water flow rate.
Washing clothes is more effective when you have this device in your house. You can also say goodbye to hard water spots on surfaces. Shower times are also more enjoyable. These benefits are possible because this system can reduce heavy metals in water.
The product also protects your metal water fixtures and pipes from rust. It draws dissolved iron across its exchange resin to improve the service life of water pipes and fixtures.
The company is kind enough to include an installation manual with the package. Connecting the system to your water supply should be hassle-free.
Unfortunately, the package does not include all the things that you need to install the system. It is important that you check the hardware that you need when you purchase this system
6. Whirlpool WHES30E Water Softener
The WHES30E Water Softener is one of the smartest ways to enjoy the many benefits of softened water in one’s home. It protects appliances that use water and reduce the risk of producing limescale on your water fixtures. Hence, you will have fewer worries about rusty water pipes.
Whirlpool designed the WHES30E as a trustworthy small water softener for apartments and houses. It comes with smart programming that takes the hassle of timely system regeneration off your shoulders.
This device regenerates on demand. The moment it senses that the salt level in the system is already low, it automatically kicks in to recharge the resin. This feature is perfect for people who may have problems adhering to a schedule. The system takes care of itself to provide you with soft water when you come home from a holiday.
The smart features of the WHES30E allow for ease of operation and maintenance. Its installation is also straightforward and simple.
The WHES30E does not only remove magnesium and calcium. It also removes up to 8 ppm of dissolved iron molecules. Thus, it is one of the highest among the compact water softeners on the market.
7. Watts Premier OFPSYS Water System
Watts Premier had all the right intentions for the OFPSYS OneFlow Plus Water System design. The remarkable system combines two water quality improvement products – water softener and water filter – in a compact design.
The OneFlow Plus features a revolutionary technology called Template-assisted Crystallization that binds calcium and magnesium into tiny crystals. These crystals do not adhere to surfaces, thus preventing the formation of limescale. It saves your water pipes, ice machine, dishwasher, washing machine, and water heater from limescale.
Another distinct advantage of the OneFlow Plus from other compact water softeners is the durability of its ion exchange resin cartridge. Many products of this type only last several tens of thousands of gallons.
The cartridge of the OneFlow Plus has a service lifespan of 250,000 gallons. You can expect about three years of continuous use before replacing the cartridge.
What surprised me about the OneFlow Plus is its small footprint. As a miniature water softener, the OneFlow Plus only requires a 9×9 inch space. You can also install this on the floor or mount it on your wall. The latter option is perfect for people who want to maximize their vertical space.
Watts Premier also included all the necessary materials you will need for installing the system. Just follow the included manuals, you should be able to put the OneFlow Plus system up and running in no time.
It is easy to appreciate the scale prevention capabilities of this softener. The integration of a carbon block filter also helps in improving the quality of water.
8. On The Go OTG3NTP3M Water Softener
One of the most interesting water softeners on the market today is the On The Go OTG3NTP3M. It is an all-new model with a smaller and lighter design than any compact water softener. While it is a mini water softener, the OTG is big in performance.
This 18-pound device is easy to carry. You can place it under your kitchen sink one day and put it in your RV the next. It can also serve as a water softener for your car wash system. You never have to worry about having water stains on your car ever again. Its footprint is also small, requiring only about 7×7 inches of space.
The On The Go OTG3NTP3M protects the different fixtures and appliances that use water. It prevents scale from forming and the formation of reddish stains on your kitchen sink.
It does this by drawing heavy metals in water and replacing them with salt compounds. You get more refreshing showers and more effective washings if you have this small device in your house or RV.
Regenerating the system is also easy. The wide-mouth opening makes it effortless to pour a box of ordinary table salt. The resin lasts a full 20 days before you recharge the system again.
The downside is that I have seen other systems completing their regeneration in five minutes. The OTG3NTP3M takes 15 minutes to complete the cycle.
Connecting this device to your water supply line is also easy. The inlet valve swivels a full 360 degrees. You will never worry about the correct positioning of the device.
9. SoftPro Portable RV Water Softener
The SoftPro Portable RV Water Softener is a low profile water softener that offers exceptional versatility. While its intended design is for recreational vehicles, homeowners will also appreciate having this unit in their small house.
It can accommodate up to 16,000 grains of dissolved heavy metals in water. And, you will find the SoftPro to be a better choice when it comes to small spaces. Its vertical clearance is low.
Carrying the SoftPro is never a problem. It is light enough for one person to haul from the house to his trailer and vice versa. The cradle base also ensures better stability in your RV. You can drive over rough terrain without the water softener tipping over.
While the SoftPro looks easy to install, I wish the package includes a manual. Not everyone knows how to install and connect the different fittings that come with the package.
The SoftPro RV Water Softener may be small, but it can do a decent job of softening your water. You can easily connect the device to any water outlet at the RV park. You can start enjoying softened water instantly.
The water softening capability of SoftPro protects the different water fixtures and pipes in your vehicle. You will be able to safeguard the optimum functionality of these objects. You can also ensure their optimum working condition for many years.
10. AFWFilters 48K-56SXT-10-1 Water Softener
The AFWFilters is the water softener of choice by people who want an advanced system that softens their water. The model uses several technologies that allow it to soften water more efficiently.
At the core of the device is the revolutionary Fleck 5600SXT digital controller. It has state-of-the-art sensors that monitor water usage. If the system ‘senses’ an increase in water demand, it automatically regenerates. This guarantees you have an unlimited and uninterrupted supply of softened water.
The technology also allows you to make simple adjustments, depending on your needs. You can increase the capacity of the system to ensure an adequate water supply.
You can also set the system to prioritize salt usage. Either way, you have a more efficient water softening system in your home with this design.
Adding to the ease of operating the device is its large digital display. You will never second-guess what setting you keyed in. The information displayed on the screen is large and readable enough for most people. The control buttons are also responsive. Choosing the correct settings should be easy.
The AFWFilters water softener for small households also has a power backup system. It keeps operating for 48 hours in case you do not have electricity in the house. You still get to enjoy your showers and wash your clothes more effectively.
I like the built-in safety mechanisms, which is a safety float to prevent overfilling the tank. If this safety mechanism fails, there is an overflow drain to catch the overflow.
Compact Water Softener Buying Guide
Water softeners require more than picking the next available device you see on the shelf of your favorite water treatment supplies store. It entails considering a few factors. The following factors can help you determine the best possible compact water softener for your needs.
Grain Capacity and Water Hardness Level
The main function of a water softener is to exchange dissolved heavy metals in water with other chemicals found in the system. The number of dissolved minerals is what we call ‘grains’.
Hard water contains many ‘grains’ of dissolved minerals, such as calcium and magnesium. The higher the grain count in water, the higher is the water’s hardness level.
It is for this reason that you should always consider the hardness level of your water. You can then compare this with the grain capacity of the system you want to buy.
The grain capacity of a water softener reflects its ability to soften the water before requiring regeneration.
In general, small home water softener systems have a grain capacity of 16,000. These water softeners can handle 16,000 grains of dissolved minerals in water before they require regeneration.
There are also systems that have a lower grain capacity of 8,000. Others are higher at 48,000.
If you have a high level of water hardness, you can expect more frequent regeneration of the system. The opposite is true if you have low water hardness levels.
Water Flow Rate
Another factor you have to consider when buying a compact water softener is the amount of water that flows through the ion exchange resin over time. The ideal water softener should provide you with the same water flow rate as the water line in your house.
If you have a water flow rate of five gallons per minute, then you should pick a device that has the same flow rate. Getting a 3 GPM unit will reduce the amount of water coming out of your faucet and other water fixtures.
You also need to consider the number of people who will use water at the same time. A 3-GPM unit is often enough for a household of two or three people. This unit may not be sufficient for a family of five. This is true if everyone uses water simultaneously.
The most efficient water softeners are those that use salts. There are also water softeners that do not use salt. However, they are not really water softeners because they do not remove the minerals that harden water. Instead, we call these systems water conditioners.
Water softeners require salts for regeneration. As such, you should check the amount of salt that the system requires every time it needs to regenerate.
Compare this with the grain capacity of the system. A system with a low grain capacity will require more frequent resin regeneration.
You should also consider the type of salt that the system requires. Some products use ordinary table salt, while others use specialty salts formulated for water softeners.
Compact water softeners are small enough to fit in spaces where standard water softeners cannot. Consider the location where you intend to place the water softener.
Take note of the measurements. Compare these measurements to the physical dimensions of the product you want to buy.
It is always nice to have a water softener that is easy to use. For example, the Culligan water softener features advanced technology that monitors the performance of its system. It saves you the hassle of always monitoring the water softener. You also need not worry about maintenance.
Other useful features include safety mechanisms, digital displays, and user-friendly controls, among others.
The best compact water softener performs as effectively as standard-sized water softeners. It allows users to save more money on the amount of salt they use. They also economize on the amount of water used for backwashing.
The ideal compact water softener should fit virtually any space. It is perfect for small homes, apartments, boats, and even recreational vehicles. Installation is never a problem.
Operation and maintenance are also a breeze. A compact water softener is the perfect solution for anyone who wants to optimize the space in their home.
