An alkaline water  filter removes contaminants like sediment, metals, bacteria, chlorine, and other chemicals. In addition to that, it changes the pH values of the water by making it more alkaline. It does this through water ionization. An alkaline water filter also adds natural minerals like magnesium and calcium. The addition of these minerals can help your body by improving blood circulation and the health of your bones. 

An alkaline water filter can provide you with great tasting water that is beneficial to your health. If you’re considering getting a water filter for your home, here are some of the best alkaline water filters available right now.

Benefits of Alkaline Water

Purchasing and installing an alkaline filter in your home is worth the investment because it will be beneficial for your health in the long run. Here are some of the benefits of alkaline water.

• It reduces the acidity in your body. Often consistent stress and a bad diet can lead to greater levels of acidity in your digestive system. Because of that, you may experience indigestion and pain. Alkaline water will help neutralize that.
• The antioxidants in alkaline water help improve your immune system.
• It can possibly help reduce the chances of getting cancer as well.

How to Install an Alkaline Water Filter

Most alkaline water filter systems are fairly easy to install. Some of them have specific instructions that are unique to that device. Always make sure to follow the instructions that come with the device before you begin the installation process. You will reduce the chances of damaging some of the components due to incorrect installation. That said, there is a fairly standard installation process, which we’ll go over in detail. Here’s what you should know on how to make alkaline water filters work effectively.

The first thing you’ll need to do is shut off the water supply in your kitchen, or wherever you’re installing the filter. This way, there won’t be any spillage during the process.

Next, you’ll have to remove the tube from the kitchen water supply. After that, install a 2-way diverter valve to the water supply. Install the tube from the filter on one end and the tube for the kitchen faucet to the other. The tube from the water supply should go into the inlet of the water filter. Once that is done, the device should be operational. Considering each of these devices has a built-in faucet, you won’t have to put the outlet tube to the kitchen tap.

Now that you’re aware of the dangers of unfiltered water, let’s look at the best reviewed alkaline water filters according to our water experts.

Best Overall Alkaline Water Filter

iSpring Under Sink Reverse Osmosis Drinking Water Filter System with Alkaline Remineralization

The iSpring water filter has a 6-stage filtration system with an alkaline remineralization filter and a reverse osmosis (RO) feature. The aim is to remove contaminants and restore alkalinity to the water. The faucet on the device has an ultra-fine filter that removes contaminants in the water to 0.0001 microns.

The RO technology in this product makes it hard to beat at this price. The water tastes great and is noticeably cleaner than what’s in the water supply. What’s more is that all of the necessary components are included. So, you don’t have to purchase any add-ons to make this product worth the investment.

The product comes with the necessary components, but the build quality is bad. The O ring provided is flimsy and much thinner than it should be. Also, the ferrule nut is made of low-quality plastic. This may break if not handled gently.

This device is also fairly large, which may make it difficult to fit under small kitchen sinks. Even if it does, you may have less space for other things under your sink. This product may be difficult to install for some people because of poor instructions. The instructions don’t mention why you must disconnect the RO membrane in the initial steps. And because of this, you may wear out the membrane if you miss out on that bit.

Pros and Cons

Here are the pros and cons of the iSpring 6-Stage Under Sink Alkaline Water Filter.

Pros

• Ro filtering works effectively
• All components and parts are included

Cons

• Poor quality components
• Requires significant space under the sink
• Poor instructions

Best Portable Alkaline Water Filter

OXA Alkaline Water Filter Pitcher

This pitcher reduces the size of the water molecules, making it easier to absorb the alkaline water. The pitcher has a total volume of 3.8L, with a filtering capacity of 2L. The product also comes with a 6-stage water filter cartridge for reducing contaminants in the water.

This alkaline water pitcher does a good job of filtering the water. Because of that, the water is cleaner and tastes considerably better. You can taste the added natural minerals as well. Also, the ionization technology works well as it ensures a pH of 8.5 or more. 

While this product has an interesting pitcher design, the lid that covers the pitcher can be faulty. It doesn’t fit tightly, meaning that it falls off every time you’re pouring water. This can result in water spillage, which can become frustrating when used frequently.

In addition to this, the filter cartridges can clog easily and don’t last as long as advertised. Therefore, frequent replacement means more costs for you in the long run.

Pros and Cons

Here are the pros and cons of the OXA Alkaline Water Pitcher.

Pros

• Water tastes great

In case you are worried that the reverse osmosis process will filter out magnesium and calcium, then you can rest assured knowing that the unit introduces these minerals back again once the reverse osmosis process is complete. You are left with high-quality mineral water that is as healthy as it is pure. The Home Master is a highly rated under-sink reverse osmosis water filter.

Before adding back the essential minerals, the efficient reverse osmosis process can about 98 percent of harmful contaminants, sediment, heavy metals, and chemicals.

Thanks to the design of the filtration system, water wastage is reduced by 80 percent. Additionally, it gets around the problem called ‘TDS creep” to give you pure water.

Other filtration systems simply rely on a filter change so that the unit performs according to expectations.

LifeStraw Go Water Filter Bottle

This water filter bottle has a carbon capsule inside the bottle that reduces the chlorine content in the water. In addition to that, it contains a hollow fiber membrane that removes 99.99% of bacteria and other parasites from the water. The 2-stage filter bottle is designed for hiking and travel, and it lasts for about 1000 gallons of water.

One of the only things that this product has going for it is the portable design. You can have filtered water on the go. So even if you need to refill your bottle when traveling, you’ll still have clean and filtered water. The filtration is adequate. That said, you’re still better off purchasing a filter at home and filling a larger bottle to take with you on the go. You could also consider purchasing CORE water bottles instead if you want clean water on the go.

One of the most disappointing things about this product is that its build-quality leaves much to be desired – which is a shame considering it’s meant to be used for hiking. It features a completely plastic design that leaks after frequent use. Also, the straw on the product doesn’t have good water flow. You’ll have to suck hard for even a bit of water. This can make the overall experience cumbersome. Some users have also reported that the water tastes bad from the bottle, including water that didn’t taste bad before being put into the bottle. The poor taste may be caused by the plastic design.

Pros and Cons

Here are the pros and cons of the LifeStraw Water Filter Bottle.

Pros

• Portable design

Cons

• Fragile build

APEC WFS-1000 Super Capacity Premium Quality 3 Stage Under-Sink Water Filter System

The APEC WFS-1000 water filtration system is a great choice for those who are shopping on a budget and need an under-sink filter that does the job well.

It delivers high value for money since it is very efficient at removing the contaminants that it has listed.

The APEC WFS-1000 uses a 3-stage process to filter out contaminants and harmful contaminants from your tap water.

Stage 1: The 5-micron polypropylene filter traps sediment, rust, dirt, sand, etc.

Stage 2: The activated carbon block filter is efficient at removing VOCs, chlorine and other organic compounds that are harmful and give your water bad taste and smell.

Stage 3: Repeat the same process in stage 2.

You may notice that the first and second stages are the same. If you want to remove additional contaminants from your drinking water then you can think about getting another filter for the 3^rd stage.

For instance, you can opt for the fluoride removal filter that is also good at trapping bacteria. The fluoride filter will bring down the fluoride content to under 0.1 parts per million. The filter makes use of alumina which relies on an oxidative reaction to remove the fluoride. This component is a reliable fluoride under-sink water filter.

You can also deploy the WFS-1000-PB carbon filter which is good for lead removal.

The filter complies with NSF Standard 53 and is, therefore, a viable method to substantially reduce lead content in water. It can last for 2,500 gallons after which it must be replaced.

There is one final upgrade that you can also select. The WFS-1000-CHLORM will work where chloramines are used for disinfection instead of chlorine. Besides chloramines, the catalytic component also removes hydrogen sulfide through oxidation. A cartridge can filter 1,500 gallons of water before it needs replacement.

The unit is engineered and assembled within the United States. The manufacturer provides a 1-year guarantee for the product.

The mineral composition of the water will remain constant besides the listed elements and compounds that product removes. Therefore, essential elements like potassium, magnesium, and calcium are not filtered out during the purification process. Essential minerals therefore remain in your water and leave it as nutritious as it was.

Since the flow rate is very good, you do not have to wait a long time for purified water. The system is suitable for municipal water supply and water that has been correctly disinfected.
