These filters are super easy to replace, simply twist and remove and then insert new one and twist tight. Takes 10 seconds. Also I have the triple stage WaterDrop filter and love the convenience of having filtered water on demand. Tastes great! We have good quality water in the area but you can taste the chlorine, but these filters remove that taste and simply taste like water, the way it should be.
Our house water always had a "milk" like flavor no matter what filter system we used, except for this one. I hated having to buy water for environmental reasons. The system this filter goes with is amazing! I haven't brought water since installing the system and the filters are very reasonable for lasting at least 6 months!
