Buyer’s Guide

Before going to purchase the best alkaline water filter, it is essential to know about those things that you should look at. So, what are those essential things, take a look. 

Type of Filtration System

First of all, it is necessary to decide what type of alkaline water filter you are going to purchase. You can either go for Undersink alkaline water filters or the alkaline water filter pitchers. Also, there are countertop alkaline water filters that get directly attached to the sink faucets. Moreover, there are also water ionizer machines that work efficiently and effectively to provide safe and healthy water. So, it all depends on your needs and budget to select a particular type of alkaline water filter. 

RO Alkaline Water Filtration System

These reverse osmosis Undersink water filtration systems come with alkaline mineral cartridges to provide safe, clean, fresh, and PH-balanced alkaline water. Many people prefer these systems because the RO membrane works effectively with other filters to remove various harmful contaminants up to 99%. And when the water reaches the post-treatment mineral cartridges, they add or restore essential and healthy minerals like magnesium, calcium, and potassium for alkalization and remineralization of water. But there are also some water filtration units such as the Express Water Alkaline Reverse Osmosis Water Filtration System that not only add minerals but also include antioxidants and oxygen into the water. 

What to look at? 

Before purchasing an RO alkaline water filter, it is necessary to make sure that the quality of the components is up to the mark. Sometimes, bad quality components make the whole system down after some time and make it ineffective. 

Many RO filtration units feature a 6-stage filtration process where different filters work together along with the RO membrane and mineral cartridges to remove various contaminants and add minerals into the water. So, it is necessary to check how many filtration stages your filter offers. Also, make sure whether it only includes minerals or antioxidants and oxygen as well. 

Other than this, you should look at the production capacity of your filtration system. How much water it can filter per day is necessary to look for. Some of the systems have a production capacity of 75 gallons per day whereas some units feature 50 gallons per day capacity. 

Also, the life span of the filter cartridges must be considered. The RO membrane generally lives longer as compared to the other filters that are used during different stages of the filtration process. 

In the end, always select that RO alkaline water filter which offers an easy installation. Every product comes with an instruction manual, but it must offer a stress-free installation. The instructions provided must be loud, clear, and easy to follow. Also, the support of videos would be a plus. 

Alkaline Water Pitchers 

Alkaline water filter pitchers are best to purchase as they are simple, quite affordable, and easy to maintain. They use effective filters to remove various contaminants from water and add minerals to provide great taste. 

These pitchers are small water containers that filter the incoming water, increase its PH value, and throw out the filtered water into the bottom. Each of them features a refilling lid through which water goes into the container. The filters then treat the water well, remove the contaminants present, make it alkaline, and throw it down to the bottom of the container. And then in order to drink water, just tilt the pitcher, and the filtered water will come out of the pour spout. 

What to look at?

If you are going to buy an alkaline water filter pitcher, then you should consider the following factors.

No. of Stages

These alkaline water filter pitchers are known for their multi-stage filters. But some filters feature fewer filtration stages whereas some carry an adequate number of stages. So, it depends on your choice as well as the number of contaminants present in your tap or well water. 

But keep this in mind that the water gets the best treatment only when the number of stages is more. The filters installed inside the pitchers remove the contaminants first and then add minerals like calcium and magnesium to make the water alkaline.  

Here one thing you need to know that not every pitcher features a filter that can remove fluoride. So, if fluoride is present in your tap water, then you must go for a system that can remove fluoride effectively. 

Size of the pitcher 

Here size of the pitcher means how much water storing capacity it offers. Some water filter pitchers can hold one liter of filtered water whereas some can handle 3.5 liters of water. Obviously it depends on the size where small size pitchers can hold a lower amount of water as compared to the bigger models. 

So, if you have a small family, then you can go for small size pitchers, but it is ideal to purchase a good size unit that can filter and store more liters of water. 

The capacity of a filter

The capacity of a filter means the life span of a filter cartridge. How much water one cartridge can treat is essential to note. Some of the cartridges need replacement after two months (150 liters) whereas some cartridges have a life span of three months (300 liters or above). So, it is better to go with a filter cartridge that features a good life span. 

Some people try to extend the lifespan of their filter cartridges by not replacing them on time. But it is a wrong and unsafe practice as it is the matter of your health. To get the optimal filter performance, you must have to replace your cartridge on time. Never try to save a few bucks by putting your health at risk. 

But it is better to avoid those companies that use proprietary filters because after purchasing a unit, they leave no choice for you except to use their replacement filters.  

Ease of use

Most of the alkaline water filter pitchers come with a simple and modern design where you can easily refill and pour water from them. But there are also some models where the refilling and pouring system are not simple. So, it is quite necessary to check your model thoroughly before purchasing.  

Filter PH Capability

Each model differs from the other one in terms of filter pH capability. Some filters are capable of maintaining pH value above 7 or 8 whereas there are some filters that can keep the pH value above 9. But not every model provides a particular pH value consistently, only some of the best models can do. 

The pH level your pitcher is offering you mainly depends on the pH value of your incoming water. 

Digital Life Indicator 

Another feature that you should look for is the filter life indicator. Most of the models have digital filter life indicators that let you know when to replace your filter cartridge. It is quite a useful feature as you can’t see the cartridge condition by yourself. Also, it is not easy to remember the months or liters of filtered water you have produced. 

So, it is mandatory to go for a model that features a digital life indicator to never miss on time filter replacement. 

Price

Price is the last factor that requires your consideration before purchasing your ideal alkaline water filter pitcher. But many people consider it first. So, it depends on you whether to consider it last or first, but one thing that is necessary to keep in mind that these pitchers are quite inexpensive, so you don’t have to worry about the pricing at all. 

Countertop Alkaline Water Filters 

The countertop alkaline water filters are divided into two types. One filtration system connects directly to your sink faucet, and the other one is the water filter pitcher that is usually placed on the top of the counter.

Here we have already discussed the alkaline water filter pitchers. So, now get into the countertop alkaline water filters that get connected with the faucets. 

What to look at? 

Filter Type

Always select a particular type of countertop alkaline water filter according to your needs. 

You can go for alkaline water filter pitchers if there is less space available around your sink or if you are using a different kind of faucet that many of the filters can’t adjust with. But one thing you must keep in mind is that water pitchers need continuous refilling as they only deliver few liters (1- 2) of filtered water at a time. 

On the other hand, if we talk about the units that are attached to the sink faucets, then these filter systems provide constant filtered water. There is no need to refill the water like the water pitchers. But one thing where these units lack is the life indicator of a filter cartridge. These filters don’t show how much life of your cartridge remains or when to replace your filter cartridge. 

Types of contaminants removal

The faucet alkaline water filters are quite capable of removing various harmful contaminants and pollutants from tap water to provide you safe and healthy drinking water. Also, they feature a mineral cartridge that adds healthy minerals. But not every model is effective in removing all the impurities present in your tap water. Therefore, it is essential to test your incoming water first to know what type of contaminants are available so that you can focus on a unit that can effectively remove all that impurities. 

The life span of a filter 

Another factor that needs your consideration before purchasing a faucet alkaline water filter is its lifespan. 

How much gallons of water your cartridge can treat before requiring replacement depends on the type of water you are getting. Some of the filter cartridges can only work effectively for up to 6 months. On the other hand, there are some that work for quite long. 

Installation

Installation is another factor that you may consider, but faucet alkaline water filters are quite easy to install. All you need is to connect your filter with the tap of your sink to get the filtered water. But not all models are designed for every type of faucet. Some are compatible with standard faucets whereas some are easy to connect with the regular sink faucets. Also, there are some filter units that are only made for the pull-down and sprayer faucets.
