The Best Alkaline Water Filters (Pitchers, Machines & Ionizers)

The best alkaline water filter offers families many health benefits, including boosting the immune system, protecting against diseases, and neutralizing stomach acids.

When families choose wisely, alkalized water filters can save people hundreds of dollars annually from buying bottled alkaline drinking water. One can contribute to a safer and cleaner environment, too.

Selecting the right alkalizing water filter to bring home requires an understanding of several factors, such as the following three buying parameters.

• Filter Type: Alkaline filters come in different types. Some families may prefer a simple filtration device, such as pitchers and countertop units. These devices are easy to install and often cost less to purchase, too. Larger households may want to choose a whole house alkaline water filter instead. These appliances can serve everyone in the house.
• Flow Rate: The more complicated the filtration technology is, the slower the filtration process. If the filtration rate is too slow, it can impact one’s drinking enjoyment. As such, it would be best to check whether the published filter flow rate is acceptable or not. For example, a 2-GPM unit may be enough for most people but not for others.
• Installation and Maintenance: Not everyone likes the idea of tinkering with a lot of things in the home. Unfortunately, some water filters require expert installation, which can increase the initial startup cost. It would be best to go for DIY designs, if not products that do not require installation.

The three product features stated above are not the only things one has to look for when buying an alkaline water filter. One can also see other factors coming into play in our buyer’s guide and read our comprehensive review of the market’s leading alkaline water filters.

What to Look for When Buying Alkaline Water Filter

An alkaline water filter is a system that utilizes electrolysis to convert tap water to alkaline water. However, like all products, these water filters have many variants that make them difficult to choose.

One does not have to worry because this buying guide will enumerate the factors one needs to know to get the best alkaline water filter.

Filter Type 

Alkaline water filters come in different options. The filter type one chooses depends on one’s needs. Here are some of the filters available.

• Ionizers: Water ionizers generally connect to the kitchen sink and are found underneath or on top of the counter. Some versions come with a dedicated faucet for convenience. This type of filter offers the best flexibility in pH regulation as it enables the user to choose the desired pH range.
• Pitchers: An alkaline water filter pitcher contains a large filter in the middle, separating the container into two parts. The upper chamber of the water filtering pitcher holds the unfiltered water, while the bottom compartment accommodates the filtered water. Due to their size, alkaline water pitchers are compact and portable.
• Countertop Filters: Countertop filters are easy to install and use. One can hook and unhook them in the kitchen sink faucet. Unlike other filters, countertop ones can’t reduce acidity; instead, they only increase alkalinity by infusing the water with alkaline minerals.
• Filtered Water Bottles: An alkaline water filter bottle is a portable and compact device suitable for people on the go. These filters come in many versions, with some featuring a straw while others offer self-cleaning elements.
• Inline Filters: Inline filters can become part of the house’s water supply. Users can connect the filter to the water supply line before a faucet or fixture. People can also install it at the point of entry to filter the water before it reaches the house.
• Reverse Osmosis Remineralizing Filters: Reverse Osmosis produces incredibly pure and clean water. However, reverse osmosis systems also tend to strip away the minerals that characterize the water with their alkaline taste. A remineralization filter can be used after reverse osmosis to add back these minerals.

Plates 

Some alkaline water systems have plates that run on electricity to complete the electrolysis process. The number of plates the system has affects the flow rate and filtering process.

Ideally, the alkaline water filter should have at least nine plates to obtain a decent flow rate and reap sufficient benefits of alkaline water. Moreover, experts recommend filters with bigger plates to promote more efficient electrical conduction and speed up the electrolysis process.

Flow Rate 

Water filter systems tend to slow down water flow rate since water needs to undergo several filters to remove harmful contaminants. Each filter has a different flow rate, affecting alkaline water output. A good rule of thumb is to look for a water filter with a flow rate of at least 0.5 GPM.

Installation and Maintenance 

The ease of installation and maintenance depends on the type of system one buys.

Typically, non-electric water filters require more effort to clean and maintain since one needs to do it manually. On the other hand, electric models generally come with self-cleaning options.

Moreover, whole-house or inline filtration systems are easier to maintain but have an intricate installation process. The smaller and compact filters only require little to no installation but might need regular cleaning.

Are Alkaline Water Filters Safe to Use

Yes, an alkaline water filter system is completely safe. It filters out contaminants and microbes, making water healthier and better-tasting.

Alkaline water has higher pH levels than regular drinking water. Whereas the latter has a neutral pH of around 7, alkaline water has a pH of 8 to 9. Aside from the alterations in the pH level, alkaline water also contains some minerals which contribute to its higher pH value.

Although its benefits are still undergoing scientific investigation, alkaline water deactivates pepsin, which is the main enzyme that causes acid reflux. Alkaline water is also great against high blood sugar levels, high cholesterol, and high blood pressure.

How Do I Change an Alkaline Water Filter

It is crucial to know if your alkaline water filter is changeable, making it easier to perform an alkaline water filter replacement and saving you money. Always replace the filter using a product specific to your alkaline water filter’s model and brand.

Filter pitchers usually come in cartridges. Take the cartridge out of the reservoir, and replace it with a new alkaline filter cartridge. Let it soak for a few minutes before drinking your alkaline water.

For countertop water systems, ensure you have the right filter for your model. Remove the filter cover, turn the filter counterclockwise to open, and remove the old filter. Insert and screw in the new filter, and place it in the close position. Turn the water on and let it run for a few minutes, depending on the instructions, before drinking.

How Often Do I Have to Change the Alkaline Filter

Water filters do not last a lifetime. Because they filter out contaminants and microbes, they need to be changed often. It is important to note that the busier the household, the more frequent the alkalize water filter change.

Water filter systems have optimum operating parameters, including filter lifespan and filter change frequency. In general, alkaline water cartridges for pitchers and countertop units need filter replacement as frequently as once every three to six months. It can change depending on how many people are in the household and the frequency of filter use.

There are filter systems that have multiple stages. A sediment pre-filter may require filter change every six to twelve months.

Changing filters will depend on the brand and the water usage. The average time that filters are changed is six months. This timespan could shorten or lengthen, so make sure to follow the correct instructions based on your kind of alkaline filter.

What are the Differences Between Alkaline Water and Regular Water

The main difference between alkaline water and regular water is their pH levels. Ordinary drinking water has a neutral pH of 7.0, while alkaline water has a higher pH, typically between 8.0 and 9.0.

Alkaline water also tastes better because it passes through a filter, tasting less chlorinated and more natural. It also neutralizes stomach acids, slows bone aging, and helps people with high cholesterol levels. If you drink alkaline water, you also get anti-aging antioxidants.

Regular and alkaline water are excellent for hydration purposes, regulating body fluid levels. However, alkaline water has the advantage of having fewer sediments and more minerals. While alkaline water is safe, it is not a substitute for medical acid-reducing therapies.

Do Alkaline Filters Remove Fluoride

Yes, an alkaline water ionizer can remove fluoride. However, it is not as efficient as other water filtration technologies. For best results, the alkaline filter must be a component of a more complex water filtration system that can include reverse osmosis, activated carbon, UV water filter, kinetic degradation fluxion, and ultrafiltration.

Alkalizing filters remove various sediments and unwanted minerals, including fluoride, to raise the water’s pH level. Depending on the filter’s fluoride removal capabilities, some fluoride ions can remain in the water.

Can Alkaline Filters Remove Contaminants

Yes, an alkaline ionizer water filter can, in a way, remove contaminants. However, if one expects the complete removal of known water impurities, one will be disappointed.

Alkalizing filters remove water toxins from your tap, giving out water with a better taste. They can remove chlorine, improving your drinking water’s taste and odor. Alkaline filters also remove other harmful contaminants.

Most alkalizing filters have multiple stages, each filtering out different contaminants, such as mud, rust, dust, and other unwanted particles that blend in with water.

These filters can also adjust the water’s mineral content, ensuring the correct amounts of magnesium and calcium in alkaline water. While alkaline filters remove various contaminants, they also keep the necessary water minerals in place. It results in clean, healthy, and highly beneficial alkaline drinking water.

Conclusion

Only the best alkaline water filter can provide families with the purest, cleanest, and healthiest drinking water. Not only do they ensure a healthier body, alkaline water filters also help lessen the environmental impact of plastic bottles while giving everyone the chance to save hundreds of dollars annually on bottled water.
