Best Citric Acid Water Softener Reviews
1. Nuvo H2O DPHB-A Water Softener System
The NuvoH2O DPHB-A Home Water Softener System is the perfect choice for anyone who needs a safe way to address hard water problems. This product has a unique chemical formulation that does not affect detergent action while also preventing limescale buildup.
At the core of this ingenious system is a citric acid chelation system that attracts and binds water hardness molecules. The technology prevents magnesium and calcium from binding with detergent surfactant molecules. The same capability makes the minerals unavailable to surfaces, leaving your pipes’ interior surface limescale-free.
Use the softened water for ensuring a more enjoyable bath, more fulfilling plants and lawn watering, and more effective washing and cleaning. You also get to protect your water fixtures and plumbing system while removing limescale buildup in these items.
With a service life equivalent to 20,000 gallons, this product makes for a cost-efficient water softener. Installing it is a breeze, giving you more savings from not hiring a plumber. Maintenance is also fret-free because there are no electrical components, no salt regeneration, and no backwashing to make you worry.
2. PurRite Shower Filter & Water Softener
Hard water makes showering quite unpleasant. It becomes almost impossible to enjoy a nice lather and feel more refreshed afterward. Your hair may also be sticky and difficult to comb. If you are already tired of showering this way, you might want to add the PurRite Shower Filter to your showerhead.
This product is compact and easy to install on your showerhead. No fancy tools or extensive plumbing experience required.
Inside this compact device is a 15-stage filtration-purification system that does several things to your water. It removes all the bad stuff that can harden the water and make showering less enjoyable.
The same filtration mechanism also removes other contaminants like chlorine, heavy metals, plus odors. Its water contaminant removal capabilities are so phenomenal that the shower water is drinkable.
Second, it adds vitamin C to water. This is why I included this product in my citric acid water softener reviews. The good news is that vitamin C can make your skin and hair healthy. The system also increases water pH by retaining beneficial minerals, making it slightly alkaline. The combination of increased pH and vitamin C is terrific news for those who want a healthier way to have showers.
3. Life Ionizer Water Filters Citric Acid Cleaning Cartridge
If you already have the Life Ionizer water filtration system, the Life Water citric acid water filter cartridge cleaner can come in handy. It is a unique citric acid solution that works as a powerful magnet, attracting limescale and other hard water minerals from your system.
I should emphasize that this product is not a replacement filter. It is a cleaner cartridge that you insert in your filter housing, run it for about 16 seconds, turn the unit off, let it sit overnight, and replace it with the original filter cartridge. You can then run your system for about three minutes to flush all the limescale and water contaminants down the drain.
Removing limescale from your system’s platinum/titanium plates extends its lifespan while improving its water contaminant-removing capabilities. It also enhances your system’s purification and alkalinization performance, ensuring safe, clean, and soft water for your family.
I have seen a water test result after using this cleaning cartridge. It removed at least 60 chemicals and particles from the system. You can imagine what will happen if these substances get into your drinking or cooking water.
While I appreciate the ease of using this citric acid cleaning cartridge, it is not a cost-effective solution. The company recommends using this cleaning product once every three to four months or about three to four times a year.
It is also worth noting that the product only works with the No. 2 filter of the company’s MX and MXL water filtration system models. It is a shame you cannot use this product to clean other water filter brands.
4. Nuvo H2O DPMB-A Manor Water Softener
Are you tired of clogged water fixtures because of limescale buildup? It would be best if you consider buying the Nuvo H2O Manor Water Softener System. This product gives you all the benefits of a salt-based water softener without the hassle of maintenance, harmful environmental effects, and tedious regeneration. Oh, you will never worry about jacking up your electric consumption, either.
This citric acid water softener is perfect for households with at least four residents. It effectively prevents and removes calcium and magnesium deposits in your water fixtures. This citric acid water filter makes it easy for you to extend your plumbing fixtures’ lifespan while also giving you the benefits of conditioned water.
If you doubt its performance, you will be glad to learn that it has NSF certification. Independent testing, validation, and certification offer greater peace of mind than having the company perform its own tests.
Installing this citric acid water softener is never a problem because it already comes with the right tools. The easy-to-read installation guide also adds to its effortless addition to your plumbing fixture.
I admire this citric acid water softener’s 50,000-gallon filter capacity. On average, you would only have to replace the cartridge every six months, and less frequently if your family uses little water like mine.
5. Aqua Eva 15-Stage Shower Filter
Like the PurRite, the Aqua Eva is a neat-looking combo filtration system perfect for the modern bathroom. It integrates the water-softening capabilities of citric acid and the water contaminant-removing properties of a standard carbon block KDF filter.
With 15 stages of filtration, this product can be a superb device to purify and soften your water. It can remove nasty odors due to chlorine, chloramine, fluoride, heavy metals, sediments, and other water contaminants. Not only will you protect your water fixture from limescale, you also get to enjoy safe water.
One of the 15 filter layers contains Vitamin C, making it a citric acid water softener-filter-purifier combo. It smoothes and softens your hair, so you won’t have to worry about hair follicle damage.
Showering will always be a delight. So is cleaning your items because there will be no limescale formation to worry you.
Installing this citric acid water softener-filter combo is also effortless. It does not take a professional plumber to get this baby working for you and your family.
While the company limits this product’s use to showerheads, it can have other applications. Regarding how else to use this citric acid water softener This Old House has a few suggestions. One of the most intriguing recommendations is to use it in specialty kitchen faucets, provided you have the right adapter.
6. Life Ionizer MX & MXL Replacement Water Filters
Water filter cartridges do not last forever. Their pores can get clogged with contaminants over time, requiring replacement. Suppose you already have the Life Ionizer system in your home. In that case, the MX & MXL Replacement Water Filters are a perfect choice.
Three filtration systems form the core of this filter. There is a unique vitamin C ceramic block filter that takes care of water-softening duties. Never again will you worry about chlorine and chloramine in your drinks.
I also like the addition of a KDF filter that works in tandem with the activated carbon block. Together, these two filter elements remove common water contaminants, such as chlorine, organic chemicals, heavy metals, and more. In fact, the filter pores are small enough to trap some bacterial species.
This citric acid water filter system is also effortless to install into your existing water filtration unit. Remove the original filter, pop this baby in, and prime your system. You should have soft and clean water for another eight months or about 800 gallons.
I know 800 gallons is not much, given that some units can filter at least 3,000 gallons. You have to note its size to appreciate how efficient this product is in its filtration duties. Additionally, some products can only filter about 500 gallons before replacement.
7. Eddy Electronic Water Softener Alternative
You might be surprised to see the Eddy Electronic Water Descaler in many citric water softener reviews. The brand is not marketing it as a citric acid water softener. Instead, it offers it as a simpler and more efficient alternative to salt softeners, which is what citric acid softeners are.
Given that a citric acid water softener’s primary purpose is to prevent limescale formation, this small electronic device does that, too. The only difference is that this device relies on electricity instead of citric acid to draw magnesium and calcium from surfaces.
Calcium, magnesium, and other hardness minerals will never stick to surfaces. This action safeguards your water and plumbing fixtures from limescale formation, extending their lifespan for several years. You can generate more savings from not purchasing water fixtures every few years or so.
Installation-wise, this product is one of the most straightforward devices. You only loop the coils around your water pipe and plug the unit into an electric outlet.
The best part is that there is no effect on water flow. Water filtration systems often reduce water flow because of water passage through a semipermeable membrane. This product does not have barriers that can impede efficient water flow.
As expected, the only downside to this descaler is its dependence on electricity. Power outages can be a real concern unless you have an emergency power backup system.
8. Hansing Water Softener System Alternative
Suppose you are looking for a saltless water softener alternative. In that case, I recommend the Hansing Whole House Water Softener System Alternative. It looks and functions like conventional salt-based water softeners, but without ever using salt.
This product has a robust design, thanks to the use of premium-quality 304 stainless steel. This metal’s unique properties give it exceptional stability against temperature and pH fluctuations. It also resists corrosion, ensuring you do not get rusty debris in your water.
I am amazed at the product’s scale-inhibiting filter design. First, there is a pleated polypropylene filter that ensures optimum water flow. It resists clogging up to 7 times better than other systems. Second, a carbon block filters up to 95% of chlorine and further reduces limescale by as much as 98%.
The performance is evident in every glass you drink. The water is crystal clear, does not have a nasty odor, and is very pleasant to drink. You will also appreciate the softened water every time you take a shower, wash your clothes or dishes, or clean your car.
The company designed the filters to accommodate up to 280,000 grains, making it far better than even the leading salt-based water softener brand. I think it is the perfect choice for families living in the countryside that depend on well water.
9. APEX 3-Stage House Water Filtration System
Most families want more than to soften their water. They also want contaminants gone from the water they use for drinking, cooking, washing, bathing, and more. Suppose you already have a citric acid water softener. In that case, you might want to invest in the APEX Whole House Water Filtration System.
This unit is perfect for complementing a citric acid water softener to provide you and your family with an efficient whole house water conditioner citric acid system. The water passes through your citric acid water softener to chelate magnesium and calcium. It then passes through the system’s three filtration layers.
A polypropylene filter forms the first layer of defense against sediments, rust, and other large particles in the water. A KDF 85 filter unit forms the core of the product, allowing it to remove unpleasant odors, mercury, iron, and other heavy metals. It is efficient enough to remove up to 99% of lead.
An NSF-certified carbon block forms the system’s third filtration layer that attracts chlorine, chloramine, VOCs, pesticides, solvents, and other organic matters. It also improves water’s overall taste and odor characteristics.
I like the filter’s design because it does not substantially impede water flow. You can still expect a generous water flow of about 15 gallons per minute, which is a lot better than the industry average of 5 gallons per minute.
10. Tier1 Essential Series Digital Water Softener
In general, citric acid water softeners are water conditioners. They do not remove calcium, magnesium, and other hardness minerals from the water. These products use different processes to prevent minerals from sticking to surfaces, mimicking the action of salt-based systems.
So, suppose you want a system that removes hardness minerals from your water. In that case, you should not get a citric acid water softener. A better solution is to get a salt-based system, such as the Tier1 Essential Series High-Efficiency Digital Water Softener.
This product features an advanced digital meter control valve that is more effective than the Fleck 5600SXT system. It is an on-demand system that counts down to the next regeneration cycle.
The controller also improves the system’s energy efficiency. It only operates as needed, unlike other products that draw electricity continuously.
I appreciate what the company did with the system’s connections. Having these components pre-installed shortens the time needed for installation. It also eliminates guesswork and the resulting frustration from not being able to put the whole system together.
11. Select Filters 18-Stage Shower Filter
It will blow you away to learn that the Select Filters Shower Filter with Vitamin C comes with 18 stages of filtration. Most shower filter products on the market can only provide up to 15 filtration layers. This design makes it one of the most exciting products any family can ever buy.
I can see several unique filtration layers in this device, including vitamin C balls, an ion-transferring resin, alkaline ceramic balls, Germanium balls, magnetic energy balls, and Maifan stone balls. There are also far-infrared ceramic balls and calcium sulfite.
The remarkable combination of filtration elements makes this product impressive enough to ask why the company limits its design to only a shower filter. I think many families will become loyal brand followers if the company can extend this device’s use beyond showerheads.
Nevertheless, I admire the product’s inclusion of Vitamin C and other agents. Protecting your showerhead and bathroom fixtures from limescale formation is straightforward. Cleaning your bathroom walls and glasses will never be a problem. Washing the sink to keep it looking pristine is also a cinch. Showering will be an enjoyable experience for everyone.
12. SpringWell Futuresoft Salt-free Water Softener
There are not many citric acid water softeners on the market. If you want a reliable alternative to a citrus based water softener, I recommend the SpringWell FutureSoft. This product works like a citric acid water softener in removing and preventing limescale formation and buildup. It is better than a salt-based system because it requires no electricity to run, and there’s no salt to harm the environment.
This water conditioner relies on an innovative Template-Assisted Crystallization technology to prevent magnesium, calcium, and other hardness minerals from sticking onto surfaces. It helps extend your water fixtures and water appliances’ lifespan, allowing you to enjoy them for many years.
I like this product’s self-adjusting mechanism. It provides a hassle-free way to account for water hardness variances. You can have high water hardness levels on some days and low levels on others. The system takes care of that for you.
I also love the unit’s water conditioning design. Most products have a capacity of only 50,000 to 100,000 gallons. This product has a water conditioning capacity of 1 million gallons, translating to about ten years. It may be expensive, but you will only replace the media after a decade or so.
The SpringWell FutureSoft may not be a citric acid water softener. However, it functions like one. It also has durable water conditioning media that should give you and your family conditioned water for the next ten years or so.
Citric Acid Water Softener Buying Guide
Buying a citric acid water softener should never be a problem for you because there are not that many products to choose from. While the idea of a water softener citric acid system is not new, very few manufacturers dare create such technologies.
The reason is quite simple. You need precise amounts of citric acid introduced into the water at any given time.
Citric acid works as a chelation agent that attracts water hardness minerals such as calcium and magnesium. Instead of these minerals sticking to surfaces, they stick to the citric acid.
Chelation agents are also important in optimizing the cleansing properties of soaps and detergents. Calcium and magnesium do not react with detergent or soap surfactant ions. They react with the chelation agent, so detergents retain their cleansing properties.
However, most of the detergents and soaps we use already contain chelation agents. Adding too much citric acid can reduce the cleansing properties of the detergent’s alkaline molecules. They will not be able to clean that much. If you use too little citric acid, it can result in partial chelation. You’ll only have ‘semi-soft’ water.
Because of these water softeners’ precise citric acid requirements, you have to admire companies that offer such products in the market. Here is how you can narrow down your choice of citric acid water softener to bring home.
- Standalone or Part of a Water Treatment System?
Some households only require limescale prevention and removal. They do not need to remove contaminants, such as chlorine, chloramine, mercury, lead, arsenic, other heavy metals, agricultural chemicals, industrial solvents, microorganisms, and more. If you are this type of person, a standalone citric acid water softener is for you.
However, if you also want to remove the contaminants mentioned above, you might need to consider a water treatment system. These products incorporate the citric acid water softener into their water filtration and purification design. Do keep in mind that these products are not inexpensive.
- Consider the System Capacity
It is essential to determine the citric acid water softener’s capacity that translates to the number of gallons of water it can ‘soften’ before requiring a replacement. The greater the softening capacity, the longer the device media’s lifespan. You can enjoy better savings this way.
- Check for Ease of Installation
Ideally, you should always get a citric acid water softener you can install yourself. It makes no sense to get a system that requires a lot of guesswork to set it up and get it running. There may also be some products that require professional installation. It is your choice whether to call the plumber or not.
- Consider Your Budget
We are not only talking about the unit’s purchase cost. You also have to factor in the replacement media. Again, the lesser the media capacity, the more frequently you will need to replace it.
How Do Citric Acid Water Softeners Work
Does citric acid soften water? Understanding how citric acid water softeners work requires learning the difference between citric acid water softener vs salt systems.
Conventional salt-based water softeners remove hardness minerals by replacing them with other ions. They store the removed hardness minerals in a substrate, ready for discharge during regular brine solution recharging.
Citric acid water softeners work the same way, except that the system never discharges magnesium, calcium, and other hardness minerals. Citric acid binds to these minerals, preventing them from sticking to surfaces. In a way, it is a water conditioner.
How Do You Use Citric Acid In A Water Softener
The only way you can use citric acid in a water softener is by installing a device that dispenses precisely-measured amounts of citric acid into the system. It is impossible to manually add citric acid you can buy from the drug store. It is difficult to determine the correct amount to add to your water softener.
Installing a citric acid water softener into your existing water filtration system as a pre-filter is best. You get to soften the water before it goes through the system’s primary filtration mechanism.
The best citric acid water softener protects your plumbing and water fixtures from limescale without ever harming the environment. It also gives you all the benefits of soft water without a traditional salt-based system’s high-maintenance requirements.
While it is not a new technology, your options are somewhat limited. Nevertheless, the products we shared in this article should give you an idea about which citric acid water softener to add to your existing water filtration system. For the best results, you might want to invest in a citric acid water softener cleaner, too.
