Product review (1 stars): I installed the second one and the flow was worse. It claims 0
I purchased this filter for my Whirlpool side by side. I couldn't get very much flow through the filter. I returned it to Lowes, they let me swap it for another one. I installed the second one and the flow was worse. It claims 0.5 GPM, I can't get a half glass in a minute. It says to flush 4 gallons of water through it. After 10 minutes, I still didn't have a gallon. I removed the filter and the flow was back to its old self. I paid $51 bucks for this, and its terrible. We are lucky that our water rates as one of the best in the country. I am through with these expensive filters.
