    Excellent value and flavor
  

*by T***Y on Reviewed in the United States on September 8, 2020*

I have an under the sink filtration system that originally used Filtrete filters. The Filtrete replacement filters are very expensive so I decided to try these WaterDrop filters and they work great. Fits my system perfectly and the flavor is perfect. The bubbles dissipate in a day or two after installing. These also come with stickers for each month as an easy reminder of when to change your filter. Very pleased with this purchase.
