Top 10 Gravity Water Filter 2020 Reviews

Are you looking for an affordable filter that takes the adventure of nature to produce clean drinking water? Then a gravity water filter is the best fit for you. To some, this item might be new to them. No worry, this article will explain the important features of gravity water filters and the reviews of the best 10 filters.

A gravity water filter is a water filter that utilizes the existing earth gravity to remove contaminants and particles from your water. This filter does it by inserting filter elements in between an upper chamber of unpurified water and a lower chamber where your clean water is stored after filtration. We understand there are many types and brands in the market, but just keep of mind of these TWO important things when you are getting one.

Product Features:

Filter Capacity: what kind of contaminants it can filter, how to fast, and check for easy replacement of filter too.

Chamber size: Think about whether you need to use it outdoors (cheaper portable type), household use (usually more expensive), or both. Check for the size of the chamber you want to be based on the number of people in your house.

Now that you know the two important factors of choosing the right gravity water filter, let’s make your mind even clearer with reviews of the best 10 products that are hot in the market right now.
