Nice little guy

I had a 5 filter RO system before, but actually never knew those make up to 5x waste water that drains down the sink. This unit is so much smaller, doesn't create waste water and doesn't require an RO backpressure tank. Honestly I can't taste any difference either, water is clean and sweet, chlorine smell completely removed. The ONLY problem I had was needed to get a 3/8 inch to 1/4 inch reducer since the old filter was all set up for 1/4, but this unit has 3/8 on it's water inlet. Simple fix, go to the hardware store and get the part. Although they do supply a 3/8 water junction you could install from the main line, I didn't want to go through the hassle. And for anyone complaining about leaks, this doesn't and you should have better understanding how these force fit water line connections work.

No more brita

We were tired of filling up Brita jugs 10 times a day, there is 5 of us at home. I purchased the Waterdrop a few weeks ago and I still don't understand why I didn't do it earlier. The installation took me about 30min. if you have very basic plumbing skills you'll do fine. The "hardest part" I guess would be drilling through the sink, other than that it's plug and play. The taste is great and the water doesn't sit in a plastic jug for hours. We probably drink more water now since it's so much more convenient. Get it and you won't regret it. Cheers!

Not bad....

This filter system is compact, and clean looking. Easy to install and maintain as each filter just twists out to replace. You do not need to shut off a water valve to replace the filters. This is a well thought out unit and it filters the very smallest particles. Some filter systems do not filter as much as this one does. The fittings and accessories are high quality, not cheap plastic. This system even has a battery powered reminder when you need to change the filters. I do not recommend RO (reverse osmosis) water systems as they take out minerals that are important to leave in. The taste with this is great. I replaced my RO system with this and am pretty happy with the purchase!

I live in Tucson Arizona where the water is pretty much on the lower end for quality and especially taste. I always thought the nasty taste and sediment was from excess mineralization but my great plumber here says most of this is caused by the chemicals used to just treat the condition. He personally uses this under the sink filter and has installed this particular unit in about 25 homes here. I was buying 5 gallon filtered water. Unit takes out many undesirables and especially tastes wonderful. I love it! Best one ever!

Removes all the impurities

I suffer from frequent headaches and since I started drinking filtered water, I've noticed a reduction in the frequency and intensity of my headaches. I believe it's because the filter removes impurities that can contribute to headaches and other health issues.
