Enjoy greater peace of mind about the water you drink at home. The Aquifer double-cartridge water filtration system effectively reduces contaminants including lead, mercury, chlorine, and pharmaceuticals in your cold water — without compromising your faucet’s performance.

I bought this about a month ago because I have well water. Our water tastes good, but since its well water I am always worried about contaminants. I choose this water filtration system because it reduces our exposure to lead, mercury and other contaminants. Also, it’s a two-stage water system that not only filters but absorbs contaminants. I like that the filters are eco-friendly and made of ground up coconut shells. This system fits under my kitchen sink without taking up hardly and space at all. The filters are easy to change. I really like that when we change the filters the water turns off automatically and I do not have to turn off the water shut off. The system was also easy for my husband to install which took less then 30 minutes. I really like this system and am thinking about putting them in my bathrooms too.

We have unfiltered well water at our house. As soon as we put this filter in the water was crystal clear. We have only had it in a few days now so I’m not sure how long it will last filtering out the sediment from our water but it has been working great! It only took my husband 45min to instal(which is good for him).

The Aquifer Double Cartridge Water Filtration System works wonderful. Installation was very easy. My husband installed it himself but it was so easy I believe I could have done it. We have city water but I just didn’t trust that everything was filtered properly so I added the Aquifer Double Cartridge Water Filtration System as a precaution. It works great, the water tastes great and I haven’t had any problems with the system itself. I would highly recommend this product, it’s a quality product that provides peace of mind with your drinking water.

I have been using my Aquifer Double-Cartridge Water Filtration System for a few weeks now and I love it. I feel healthy drinking my faucet water knowing that it is filtering out all the extras added to water. I also love that it uses ground-up coconut shells, making it more eco-friendly than charcoal.

This filtration system was very easy to install. Took about 15 minutes. The water tasted better almost immediately, ( we have crummy water) It only hooks up to the cold water and the filters will last for 6 months. This is a great product and is better than some of those products that you hook up to the faucet. Would recommend!!

This is a top notch water filtration system, it effectively delivers filtered drinking water that reduces the pharmaceuticals and contaminants that is put into the water, it is also eco friendly having a crushed coconut shell based filter, this was super easy to install, it goes right underneath your sink.I feel so much better having bought this for my family as we drink a lot of water and now we can drink from the tap worry free.

This is a great system for the kitchen. It’s pretty compact so doesnt take up a ton of room. We installed it in our kitchen sink. Theres also a garbage disposal and instant hot water but still plenty of room for this. Installation is fairly straightforward but you will have to have basic plumbing knowledge to install this. I like that I can now have clean filtered water from the faucet instead of having to get it from the fridge. The water from this filter tastes really clean with no hint of minerals. I feel better about drinking from the tap knowing that I am drinking clean and filtered water. This is a high quality product and I am very happy with everything.

At first glance, this system is HUGE. When i swapped out my old system, this one had larger hoses, larger cartridges, larger everything. However, it’s easy to install and the water tastes great. Its as if you’re drinking water from the alps it tastes so clean. With all the choices to beverages, there really isnt anything that beats old fashioned clean refreshing water.
