Countertop Gravity Water Filter Reviews | Watens VS Berkey VS Propur VS Alexapure

4 hours ago Product Review 17082

It seems normal to drink tap water daily because it’s cheap and convenient, but it is still a hazard to your health. Before tap water reaches your glass, it picks up numerous contaminants, viruses and bacteria from water treatment, poorly maintained infrastructure and rusty faucet. Studies reveal drinking unsafe tap water will suffer from cancer. Even your community water system which meets the national drinking water standards may also bring some health risks. So having healthy water is a must that you should be aware of, especially when you have children in your family. The countertop gravity water filters are the easiest way to transfer your tap water into clean drinking water.  

What is a Countertop Gravity Water Filter?

The gravity water filter system is often composed of two chambers, the upper chamber and the lower chamber. These chambers are usually stainless steel containers for corrosion prevention and easy cleaning. The water will be poured into the upper chamber, then drained through two or more filter cartridges into the lower chamber by the “pulling force” of gravity. The lower container is fitted with a small tap, from which you can access reliable filtered water. The gravity water purifier is perfect due to its convenience and it doesn’t require electricity or plumbing. So, either on hiking or at home, you can use the gravity water filter for safe and clean water.
