6 Best Water Filter For Limescale [2021]: Remove Calcium and Lime From Tap Water

What is Limescale?

Limescale is an off-white colored solid deposit that is often found inside water pipes, water heaters, boilers, kettles, coffee machines, etc. Limescale is, mostly, made of Calcium ions and Magnesium ions.

Hard water is the primary reason for limescale build-up. Hard water refers to water that has a high amount of dissolved calcium and magnesium in it. Along with hard water, those ions come inside our water pipes and other home appliances. They have a tendency to stick to metal pipes and convert them to carbonates (calcium carbonate & magnesium carbonate) through a chemical reaction. Over time, when enough carbonates get together, they create layers of visible white coat known as limescale.

How To Remove Limescale From Tap Water?

According to the United States, Geological Survey, 85% of people in the USA have hard water and suffer from limescale problems. Now, there are 4 ways you can remove limescale from tap water.

1) Water Softener and Water Filters Combo: Water Softener & Water Filter are the best combination to prevent limescale. A water softener turns hard water into soft water by crystallizing the hardness-causing ions. And the filter removes any kind of dirt, sand, rust, virus, bad odor, and non-organic contaminants from water. The water softener and filter combo provide healthy, purified & soft water to every faucet in your home. Thus, it protects you and your entire house from limescale

A good quality water softener can also break down and wash away previously built limescale inside old water pipes. Which in turn, increases water pressure and saves the cost of replacing plumbing in old houses.

2) Reverse Osmosis Water Filters: Most accurate limescale water filters to remove limescale drinking and cooking water. A reverse osmosis filter uses its fine-pored filter cartridges to completely extract hardness causing calcium and magnesium ions from water. Thus, removing the salty taste of limescale-contaminated water.

3) Scale Inhibitor Filters: Most affordable and one-time-use filters that are suitable to protect individual home appliances, like a tankless water heater or a washing machine, from limescale. If you want to protect multiple devices, you will need to purchase multiple scale inhibitor filters.

4) Limescale Shower Filter: A Limescale Shower Filter gets attached to your existing showerhead and proves soft water during the shower. It is an easy, quick, and affordable option to get soft water in the bathroom. A shower filter can save you from redness, itchy skin, and rashes that occur due to showering in hard water. It can also reduce hair falls and make it look shinier.

Now, let’s introduce you to the 6 best water filters for limescale that you can buy to get rid of hard water & limescale.

1. Express Water’s Whole House Polyphosphate Anti-Scale Water Filter: Best Under Sink Water Filter For Limescale

To those who are looking for a compact and more-affordable limescale filter, we recommend Express Water’s whole house antiscale water filter. It is a 2-in-1 water filter that prevents scaling and purifies water at the same time. Instead of salt, it uses polyphosphate crystal beads to disrupt scale formation. Although it’s a whole house antiscale filter, it’s not as powerful as a dedicated water softener. If you have low-to-moderate hard water in your home, then it will be the perfect limescale water filter for you.

Does Drinking Water in Your House Smell like Rotten Eggs? Ask an Expert, Why?

SpringWell Reverse Osmosis Drinking System: America's No.1 Water Solution For Homes

For whom Express Water’s Whole House Polyphosphate Anti-Scale Water Filter was designed and manufactured? People who live in city apartments/ urban areas and get pre-filtered water from a water purification plant are the ideal users of Express Water’s whole house anti-scale water filter. Usually, apartments don’t have much free space to install a bulky water filtration system. Thanks to Express Water’s compact size it can be installed under a sink or in crawl spaces.

One more thing, we don’t recommend using it with well water. Because private well water contains a lot more and a wide variety of impurities than city water. If you use it to filter well water, you will have to change its filter cartridges frequently ( once every 4-5 months).

How does the Express Anti-Scale Filter terminate scale formation and purify water? The Express whole house water filter uses a 3-Stage filtration process. For this, it uses 3 different filter cartridges.

Stage 1: At the first line of defense against water pollutants stands a Sediment (SED) Filter. It is made of precision-packed food-grade polypropylene microfiber. Any contaminants that are equal to or bigger than 5 microns get removed at this stage. The sediment filter has got multiple layers. The outer layers are designed to remove the coarsest impurities and the inner layers are to remove finer sediments and particles.

Stage 2: At the middle of the defense line stands a Polyphosphate (PHO) Filter. It battles mostly against silt, rust, dirt, and existing scale and prevents the formation of scale and corrosion. The PHO filter holds food-grade slow-dissolve Sodium Polyphosphate crystal beads inside it. When water passes through it, the crystal beads bind the receptors of calcium ions. Making scale formation impossible.

Stage 3: At the last stage, the Activated Carbon Block (ACB) filter captures Chlorine, Total Organic Carbon (TOC), Pharmaceuticals, Turbidity, and Chemicals causing bad tastes and odors from income water. It is mainly responsible for providing fresh, healthy, and somewhat tasty water to your faucet.

How fast does it provide soft & healthy water? The Express antiscale water filter can provide 12-1 gallons of water per minute. Practically speaking, it is more than enough to fulfill the water demand of 2 bathrooms and 1 kitchen simultaneously.

How frequently will you need to change the filter cartridges? Depending on the quality of incoming water in your house, the water filter cartridges can purify up to 100,000 gallons. Considering you have a family of four, Express Water’s antiscale limescale water filter will last for 9-12 months.

Does the Express Anti-Scale water filter come with any warranty? To protect your investment in this water filter, the manufacturer provides a 1-year limited warranty.

2. AquaBliss High Output Revitalizing Shower Filter: Best Shower Filter For Limescale

Apart from scale buildup, hard water can also make you feel itchy during the shower. Magnesium and calcium ions present in hard water can increase dandruff, increase hair falls and damage your nails, etc. In order to prevent that, we recommend using a shower water filter for limescale. And, as a limescale shower water filter, our first choice is the AquaBliss High Output Revitalizing Shower Filter. It’s a metal-made universally compatible filter that can block Chlorine, pharmaceuticals, pesticides, dirt, and odors from your shower water.

Is AquaBliss Shower Filter compatible with your existing showerhead? The AquaBliss shower filter is compatible with almost every handheld, standard, and rainfall shower. You can install the filter with your bare hands. Simply twist off your shower head, twist on the shower filter and then reattach your shower head. It is as simple as that.

How does Aquabliss protect you from hard water? The filter cartridge inside the Aquabliss shower filter has multiple layers consisting of sediment filter, redox media, calcium sulfate, activated carbon, and ceramic beads. All these filters work in sync and turn hard water into soft water. They also remove pesticides, chlorine, dirt, and odor. The ceramic beads used inside the filter revitalize water for you to have itch-free skin, shiny hair, and strong nails.

How much does it cost to use an Aquabliss shower filter? Aquabliss is an extremely affordable filter. It costs only 0.09 per day to use it.

3. 3M Aqua-Pure Scale Inhibition Inline Water System: Best inline Water Filter For Limescale

If you are not willing to spend money on a water softener and only need to protect a single instrument from limescale, an inline scale inhibitor will be the perfect choice for you. As a budget-friendly scale inhibitor, 3M Aqua-Pure is the best water filter to protect your home appliances like tankless water heaters, water boilers, kitchen faucets, etc. Sure, It can’t save your entire plumbing system from limescale. But as a point of use scale inhibitor, its performance is outstanding. Interestingly, it can also be attached to showerheads to get soft water in the bathroom.

Build Quality and Installation: 3M Aqua-Pure is a one-time use scale inhibitor. It looks like a bottle that has a robust stainless steel head on top of it. With a simple twist, it gets attached to the inlet pipe of your water heaters.

How does 3M Aqua-Pure protect home appliances from limescale? 3M Aqua-Pure uses Polyphosphates ( in short amounts) to prevent limescale build-up. Polyphosphate is a kind of salt that dissolves into the water. It chemically changes the chemical structure of scale-forming ions and thus inhibits corrosion and scale deposits.

Can 3M Aqua-Pure keep up the water flow of a water heater/ washing machine? Aqua pure is designed to match the water flow rate of most water heaters, washing machines, dishwashers, etc. on the market. A whooping,10 gallons of water can pass through the 3M Aqua-Pure scale inhibitor in a minute. Even the most powerful water heater/ washing machine does not require a 10 GPM water flow rate.

What is the expected lifespan of this scale inhibitor? Depending on the water requirement, water quality, and hardness of water, 3M Aqua-Pure has a life span of 6 months.

Warranty: No warranty is available on this product.

4. Nakii Water Filter Pitcher: Best Water Filter Jug For Limescale

Since hard water contains highly concentrated magnesium and calcium ions, it has a salty & bitter taste. Something that is not ideal for drinking or making coffee, tea, juice, etc. In order to eliminate the odd taste of limescale, you can use the Nakii water filter pitcher. It’s a fast and affordable water filter that uses activated carbon fiber to remove impurities from water. Remember, you can’t expect it to have the same level of purification as of a reverse osmosis water filter.

5. SpringWell Whole House Water Filter and Salt-Free Water Conditioner System: Best limescale treatment for the whole house

Our first choice to fight against limescale is SpringWell’s Salt-Free Water Softener system along with their NSF-Certified Whole House Water Filter System named “Rhino”. To be accurate, it’s not a water softener rather than a water conditioner because it does not use any kind of salt to turn hard water into soft water. But we will call it a softener anyway since the manufacturer does. It is a heavy-duty maintenance-free water softener that you can connect to your waterlines. Once installed, it can protect your home’s pipes, plumbing, and appliances from scale buildup for up to 6-years. And, the high-performance water filter provides great-tasting, healthy water from every tap in your home.

• SpringWell whole house water filter and Salt-free Water Conditioner Combo is a complete water treatment setup that provides value for your money.
• Suitable for big families, motels, and offices that need a ton of water every day.
• The salt-free water softener turns hard water into soft water by a physical crystallization process.
• The water filter can purify up to 1 million gallons of both city and well water in its service life.
• 100% maintenance-free, No electricity required. It also doesn’t need drainage for wastewater, or heavy bags of salt to lug around.
• It is capable of filtering debris, rust, sediments, bad odor, chlorine, herbicides, pesticides, PFOA/PFOS, VOC, etc. from water.
• The maximum water purifying rate is 12 Gallons per minute.
• It provides a 6-month money-back guarantee & a lifetime warranty.

How does SpringWell Scale Control Technology turn hard water into soft water?: After years of trial and error, SpringWell invented its Scale Control Media (SCM) technology. Unlike ion exchange used by salt-based water softeners, it’s a physical process that turns hardness-causing minerals of hard water into harmless crystals. Those crystals do not stick to water pipes or to your faucet, thus preventing limescale and hard water build-up. Since the system doesn’t add salt to the water, it doesn’t taste salty.

Springwell’s salt-free softener uses an upflow softening tank and stores water softener media in it. The smart design of the tank and its ActivFlow technology lets the water flow through the media and instantly crystallize. Springwell perfected their system to a level that the water softener works perfectly even at the lowest water flow of 5 GPM to the highest water flow of 12 GPM.

How does the Springwell water filtration system work? The whole house filter system uses 3 filters in total to remove water contaminants. City-water/ Well-Water first goes through a Sediment Pre-Filter. It works as the first line of defense that removes debris, rust, and sediments that can clog the system. Then the water goes through the main Rhino-Filter, which holds copper-zinc and mineral stones. They remove herbicides, pesticides, PFOA/PFOS, VOC, etc. After that, water goes through a post-filter which further polishes the water before sending it to the faucet.

How much soft water does the water softener produce? You will get a 12 gallon per minute water flow rate out of a Springwell water filter + water softener combo. Enough to meet the water demand of 3+ bathrooms simultaneously.

Does Springwell’s salt-free water conditioner need maintenance? As we have said before, the salt-free water softener is a maintenance-free system. Once you set up the system, it will remain effective for the next 10 years. The city water filter can stay effective for 10 years/ 1 million gallons.

Will you get any kind of warranty or guarantee from Springwell? You will get a 6-month money-back and a lifetime warranty.

6. AquaTru Countertop Reverse Osmosis Water Filter: Best Water Filter Pitcher For Limescale (Reverse Osmosis)

As of now, AquaTru countertop reverse osmosis water filter is the best water filter pitcher for limescale. It’s an effective, hassle-free, plug-and-play type water filter. You put tap water in it, plug it in an electrical socket, and within seconds it starts filtering water for you. If you are a professional chef/baker, you will love the AquaTru. Because it can eliminate calcium and magnesium ions from drinking and cooking water with 100% accuracy. Purified water by AquaTru does not have the sliest smell.

Build Quality and Design: As a water filter pitcher, we would say Aquatru is pretty compact and lightweight. It weighs only 16 pounds and is made of long-lasting premium-quality plastic. Since it’s a countertop water filter pitcher it does not need any installation. Although, it does need electricity to run.

Water filtration system: AquaTru has 2 detachable side tanks. One is for tap water and the other one is for filtered water. You simply fill up the “tap water tank”, start the system and, a few minutes later, get 100% purified water in the “filtered water tank”.

Aquatru uses 3 composite filters to produce fresh drinking water for you. The first one is a Pre/ Activated Carbon filter, the second one is a RO Filter and the third one is a VOC Filter. Altogether, these filters remove contaminants including arsenic, uranium, nitrates, limescale, pfas, etc. Thus, it improves water quality.

Water Flow Rate: Aquatru can produce 1 gallon of drinkable water every 12-15 minutes.

Maintenance: You will need to change those water filters after consuming 600-1200 gallons of water. For a standard family, that is about 9-12 months’ worth of drinking water.

Warranty: Aquatru gives you a one-year limited warranty for their water filters.

Best Water Filter for Limescale: Buying Guide

1. Salt vs Salt-free water softeners: No More Limescale

Salt-Based water softeners and salt-free water conditioners are both effective against hard water. But, we recommend a salt-free water conditioner over a salt-based water softener for a few reasons. Such as:

A Salt-based water softener softens hard water by replacing the calcium ions with sodium ions. They provide you with the full range of benefits of water softeners, including limescale prevention, softer skin, preventing hair fall, and preventing stains and soap scum. They usually cost less than a salt-free water conditioner. The major downside of salt-based water softeners is that they increase the number of Total Dissolve Solids (TDS) of water by adding salt. TDS is a measure of the total concentration of dissolved minerals in the water. An increased amount of TDS in water is not good for human health. Also, the discharged salt brine water from a salt-based softener containing sodium and calcium is not eco-friendly at all. That’s state like California sets an example by banning salt-based water softeners.

Also, a salt-based softener needs frequent maintenance. Every 7-10 days new salt needs to be added to the system, which is a big hassle in the long term.

On the other hand, a salt-free water conditioner does have those drawbacks. It does not need maintenance, nor does increase TDS. Take Aquasana Salt-free water conditioner, for example. Once you installed it in your house, you won’t even need to touch it for 6 years. For six years, it will soften water for you. That’s why a salt-free water conditioner, Specially Aquasana’s water conditioner, is our first choice to prevent limescale from limescale.

2. Water Supply Rate:

Before buying water softeners, you need to figure out the daily water requirements per day.

In the case of the whole house water filter+ softener combo,

According to American standards, every person needs 80-100 gallons of water per day. And, a filter+softener with a 10-11 GPM water supply rate is enough for a family 0f 4-5 people.If you have more than 6 people in your house, you should choose a bigger filter+softener with a higher water flow rate of 14-15 GPM per hour.

In the case of Reverse Osmosis water filter,

Every person needs 8-10 gallons of drinking water per day. An RO water filter that provides 40-50 gallons is good enough for 4-5 people. But if you need more water, you will do well enough to choose a tankless RO water filter that can provide 400-500 gallons of water per day.

Disadvantages of Limescale In Water

1. Reduces the Lifespan Of your water pipes:

Limescale deposits are the worst enemies of metal water pipes. Limescale clogs your water pipes and reduces the water flow by a significant percentage. In order to maintain normal water flow, your water pipe needs to work harder. High pressure on water pumps leads to failure. And if the limescale completely blocks your water pipes, you have no option but to change your entire water pipe system. Leading you to a loss of at least 4000-5000 thousand dollars.

2. Destroy water heaters and Increase monthly utility Bill:

Here in the U.S.A., almost every family uses water heaters. We all know, water heaters use heat exchangers to transfer heat to the water. Limescale creates a layer around the heat exchanger. That layer hampers the heat exchanging process and thus drastically decreases the efficiency of a water heater. It causes the heat exchanger to overheat and ultimately fail. Until then, the water heater uses more energy than needed and thus increases the monthly utility bill.

3. Hard Water causes itchy and increases hair fall:

Scale forming Calcium and magnesium ions in hard water creates a hard lather when it comes in contact with soap. That lather is somewhat difficult to completely wash away and tends to sit on your scalp and skin. Upon clogging your skin pores, it causes excessive hair fall, itchy skin, increased sebum, acne, etc.

4. Limescale in driving water might lead you to kidney-Stones problems:

Although there is no proven negative health impact, some researchers say that drinking salty water, that has a high amount of calcium and magnesium in it, might be a cause of kidney stone diseases. Until completely proven, we would say it’s better to be safe than be sorry.
