Query: Keep away from it

I had one a few months ago. When I filled in water, the water just passed the filter quickly. I was not sure if the water is filtered. One day, I wanted to clean it. I put it in hot water for about 10 minutes. The pitcher was out of shape and I had to discard it. I believe the pitcher was made from cheap materials. I sent an email to the custom no service of Brita. I got no response. I will not buy Brita products any longer.
