Buyer’s Guide: To Consider The Factors While Buying The Best Alkaline Whole House Water Filter System

It would be best to consider a few things while investing in the best whole-house water filtration and softener system. The first thing you must keep in mind is the quality of your tap or healthy water—and the cost of buying a filter in the long run. It would be best to ensure a proper filtration system is installed with your water ionizer. Depending on your preference, it can be a reverse osmosis water filter or a whole-house water filter. The whole house water filtration system cost is now accessible to everyone.
After doing your research, picking the filtration system best suited for you will be easy.


After you have selected your desired alkaline water filter, You can face two situations when it comes to installation.
Suppose you have bought an alkaline water filtering system with an under-sink filtration system with Remineralization like Frizzlife. In that case, you have to install the whole filtration system with the help of a plumber. That would be an increase in the installation cost.
If you opted for a high-end ionizer, those filter systems are easy to install, and you can do them yourself after reading the installation manual. Still, I suggest you install an alkaline water filter with your ionizer.

Removal of contaminants

The removal of contaminants depends upon the type of whole-house water softener and filtration system you have chosen. Choosing a whole-house reverse osmosis water filter is better because it is an all-rounder water filter and will remove all the contaminants from your water, including chlorine, lead, and other heavy metals.
Even most ionizers filter out the primary contaminants and adjust pH according to your tastes, so you get a two-in-one system with the most alkalizing filtration solutions.

Multi-stage Filtration

Most alkaline water filter pitchers, ionizers, and other whole-house water filters, including under-sink filtration systems and water filtration reverse osmosis technologies, use multi-stage filtration. These best whole-house water filtration and softener systems have sediment filters, RO membranes as a pre-filter, remineralization filter, and water ionizers post-filtration.

In the case of ionizers, water passes through ionization and calcium carbonate beds to ensure that water has been up to the optimum ph and essential minerals.

You should consider the product with ultra-filtration, in which water runs through the filtering units and remove more than 99% of contaminants. 

Balancing pH

To determine the whole house water filter ph, you should monitor your water. First, it’s acidic or alkaline. Many methods to test water pH without a kit and using kits are available. The pH meter, strips, pH indicators, and litmus papers are very convenient sources for detecting the water’s pH.

In all probability, your principal justification behind putting resources into an alkaline water filter is to profit from water with high alkalinity. For this reason, you need to comprehend the pH range. Water has a pH of around 6.5 to 8.5. With seven being unbiased, most drinking water sources are excessively acidic for our loving. 

Some water ionizers have a versatile pH range that allows you to browse exceptionally acidic to extremely basic. You may not need this degree of adaptability if you’re hoping to build the pH of your water. Yet, you might think it is helpful to create both acidic and alkalized water (for example, water with a low pH is ideal for cleaning). 

Many alkaline water filtration arrangements on this rundown don’t allow you to choose a particular pH to create water at, so ensure you pick probably the best framework for your needs.

Alkaline Water Filter and Remineralization

You must ensure that the whole house water filter you choose must have an alkaline water filter that will remineralize your water for the best quality.

The types of whole-house water filters, such as countertop and under-sink water filtration systems, use remineralization technology to make reverse osmosis water alkaline and expel the acidity in water to make it healthier to drink.

Flow rate

Most filtrations frameworks, including alkaline filters, will decrease your water flow by a minimum. It bodes well because the water goes through a few fine-grain channels that eliminate each impurity it can discover. Flow rates will fluctuate from one framework to another, mainly depending on how quickly the ionizing system takes inside the electrolysis. The more plates will have more significant surface space, the faster they will filter water.

Filter’s lifespan

The whole house water filter replacement life span depends upon the quality of your tap water. If your tap water is dirty and full of sediments and dirt, it is more likely that your filters will run out soon.
On average, the filter lifespan is about 2-3 months, but if you have less troubled water, your filters can last up to six months.

The best whole-house water filtration system has a long-lasting life span and a greater capacity for water production. The filter should have a lifespan minimum of 6-8 months.


Ensure you don’t accept an alkaline water filter until you’ve investigated its guarantee. If you get a defective item, you need to realize that you have the maker’s guarantee and can return it for a discount or substitution. Mistakes in assembling are usual, and you would prefer not to be left in obscurity if a thing shows up in a not-precisely great state. 

The standard guarantee for an alkaline filter is five years, yet some go higher than this, and some even have restricted lifetime guarantees. Higher security is particularly significant with items you’ve spent massive cash on, forthright, and those that expect power to work. Ensure you’re acquainted with a guarantee’s terms, which differ from one item to another, before you feel free to make a buy.


The cleaning and maintenance of your water alkaline water filter depending on your type of water filter. If you have an under-the-sink water filter, you have more work on your hands because you flush the filters with cold water to remove unwanted particles.
An electric ionizer has backflush carbon or sediment filters to clean them. Cleaning the ionizer and alkalizer is relatively easy and doesn’t need much effort.
Most ionizers have self-cleaning models, so they don’t need much maintenance. Some models have scheduled built-in timers that detect filters’ cleaning time.


Filters are available for all budgets. The whole house water filtration system cost is reasonable and convenient. For example, an excellent alkalizing water bottle may be found for less than $50, and filter pitchers are usually in the same price range.
