Frequently Asked Questions:

Are Alkaline Water Filters Safe?

Yes, they are safe. High-quality products, such as the ones on our list, filter natural minerals into your water, increasing its alkalinity. Typically, they come with in-depth instructions that highlight built-in safety measures, to put your mind at ease.

Is Having an Alkaline Filter in Your Home Important?

Alkaline water is becoming increasingly popular due to its many benefits. However, these filtration systems provide more than just pH balance and better taste, they also clean potentially harmful impurities and contaminants from your water. 

What is the Difference Between Alkaline Water Filters and Reverse Osmosis Filters?

While reverse osmosis, or RO, systems usually clean water of contaminants or harmful bacterias, not all of them produce alkaline water. 

Alkaline water filters balance out the pH levels in the water, which in turn helps balance the acids in the body. Some consumers even say an alkaline filter makes the water taste and feel more refreshing.

Wrap Up

Installing an alkaline filter is a smart line of defense in possibly lowering harmful acids in your body. It is safe to say that the potential benefits go farther than purifying your water. Adding an alkaline water filter to enhance your daily water intake is an excellent start to improving your everyday wellbeing.
