The Zero Water Pitcher does come with a filter.
All of the Zero Water Pitchers comes with a 5 stage filter that filters the water to make it safe and more tasty.
Every single water filter pitcher from Zero Water includes a 5-stage filtration system that delivers pure-tasting water right to you
The Zero Water Pitchers and ALL Zero water dispensers come with a filter and FREE Water Quality Meter.
You can use the water quality meter to test the water for any impurities or other unsafe contaminates that may be in the water.
I have a Zero Water Pitcher and use the water tester meter as well and it works great.
So far my water has been safe to drink but the Zero Water Pitcher helps filter the water and make it taste much better.
