Whether you intend to acquire a water filter for your home to drink clean/safe water or you’re a business owner trying to boost the operations of your company with modern water filtration solutions, getting to know the water filter manufacturers we’re going to talk about today is a must for you. Let’s begin with the primary water filtration information you need to know and head right into the list of companies afterward.

What is a Water Filter?

A water filter is a necessary device that eliminates impurities and contaminants in water to improve its quality. It uses distinct mechanisms to purify water as a kind of barrier between the source of water and where it’s consumed. 

Water filters can remove various pollutants such as sediments, chlorine, bacteria, and heavy metals. They’re commonly used in homes, mostly integrated into faucets and pitchers, or connected to plumbing systems. 

The filtration techniques used in water filters can have different formats, including physical barriers that trap particles and chemical processes that neutralize harmful substances. In any case, the main objective of these filters is to deliver safe and clean water as they notably diminish the presence of substances that might lead to health hazards or badly affect the taste/odor of the water.
