Bought this on Amazon since my reg dealer didn’t have it. Did my research and found this one. It was 37.00 and the other filter was 57.00. No brained and it works great. Will buy again

I needed to run the water for 15 minutes before the color settled down, but water tastes good and it feels good knowing that I am filtering my local water (especially after getting notice that there are "acceptable" levels of arsenic in our town water.)

All was as advertised and expected. I ordered this product because the usual was unavailable. The product installed easily and fit fine, but it's too soon to know the quality of the post-filter water or how long the filter will perform. These folks are wanting a review so fervently so I give you the above.

Met expectations.

Chlorine taste removed, slight pressure drop, last for a year or more, good product

Took only a few minutes to install and was a piece of cake. One suggestion: When you open the package aim the red cap away from your face. Mine shot across the room and hit the door. Also be prepared for compressed air to hiss and to blow out of the faucet once attached. You need to run the water for 5 min per the instructions after you install it. Some black matter came out of the faucet when it first was connected and I assume it was the carbon in the filter as stated in the instructions. This stops after a few moments. The price was less than a third of the original. Water tastes great and I am quite happy with the outcome. Lots cheaper than bottled water.

I bought this filter to save some money. The Filtrate filter that I have always used has gone up in price to around $55. I saw on Amazon that this Waterdrop filter was comparable with the Filtrate filter. There were only 2 things that I did notice between the 2 filters that differed 1) After replacing my old Filtrate filter with the Waterdrop filter, as you know, you must let the water run through the new replaced filter for several minutes. I collect the water in a plastic pitcher and use the water on outdoor flowers. I noticed this water collected had much more charcoal residue than the filtrate on this initial "flushing." In fact the pitcher that I use is white and it became very discolored from the 2 collections of water. It was so discolored I used clorax and water to to try and remove the discoloration after it wouldn't wash out with just dish detergent and water alone. The second thing I have noticed is the water flow from the faucet is much more forceful than the previous Filtrate one. The water has no bad taste. The initial discoloration is gone. So I am assuming that it all is ok. These 2 observations do make me a little curious, but I am using the filter and letting the curiosity go!

Installation was extremely easy. Flavor of water is good - same as before. The flow actually is better than the one that was replaced. Great value for money.
