Description of PureDrop CUW4 Aquacube Tankless Filtration

[Better-tasting Water]: The 4-stage multipurpose undersink water filtration system with its 0. 01 micron Ultra Filtration (UF) stage removes up to 99% of most problematic pollutants, including chlorine and chlorine treatment by-products, lead, arsenic, and much more while retaining minerals. [Efficient and Convenient]: Enjoy a faster water flow (0. 32-0. 5 GPM vs 0. 03 GPM with traditional water filter systems). The unit can be placed under the sink or connected to your refrigerator(ICEK needed). The elegant, modern, compact design needs no tank, wastes no water, and provides ultra-quiet operation. Stay informed on your filter’s status with the integrated LED filter change indicator. Just press and hold both buttons to start. [Easy Installation and Maintenance]: Cut hassles, not corners with a typical installation time of less than 30 minutes. The unique design of the integrated water route reduces installation time dramatically, and the click-on filter installation ensures easy installation and maintenance. [Durable and Reliable]:All filters, tubing and other water-contacting parts are manufactured to comply strictly with industry and NSF/ANSI standards. Please feel free to contact us if you have any questions. We always put our customer satisfaction as our top priority and reply as soon as possible. [TDS Note]: This is a 0.01-micron Ultra Filtration(UF) unit and will not reduce the TDS of the incoming water. Instead, it keeps the minerals in your water. If you are interested in a filter that removes TDS, please consider a reverse osmosis system like the PureDrop RTW5.

The best filter for $!

I wanted/needed a filter because local water contains Chromium 6. This filter solved the problem. Installation was very easy and took me (grandma) about 20 minutes, and I didn't need any special tools or tape. My counter already had a hole previously used for a soap dispenser which I unplugged and used for the spigot. I had a little problem connecting the outlet hose to the spigot, but only because it was in an awkward position for me and I couldn't push the connection hard enough. Although my…

Rating still good for kitchen and bathroom faucets

We love the design, ease of installation and quality of materials on this filter, but after about 30 days of use the water starts to smell strongly of sewage. . After research, we found that it could be a build up of anaerobic bacteria in one of the filters. However, there are no instructions or ways to fix such issues other than contacting the company for a new filter. We called iSpring and after agreement they asked us to apply on their website. We have and will update this review based on…

Excellent filtration system

After researching several different systems and having owned traditional reverse osmosis systems for several years, I ordered this compact unit. It was easy to fit in the vanity in my space-constrained home. It comes with all the parts you need to install in less than 30 minutes. I was drinking pure pure water in no time. I also use it to make ice cubes that don't leave any suspended particles in my glass. Definitely happy with this device! Updated July 20th! All 4 filters replaced after more…

  • Easy to install

Excellent Water Filtering and Softening System

I have city water where I live and wasn't interested in a reverse osmosis system so this filter seemed like a good choice. It works great, delivering 'clean' water filtered through four separate filters that last a long time (depending on how much water you use) and are very easy to replace. The plumbing was a bit of a problem but it was the plumbing in the house and I don't think it would be a problem in more modern homes. filtered water remained crystal clear. This is the perfect way to…

Pros
  • Certified

Great price easy install

This is the first of its kind with 4 filters and no reservoir. No drain seat is required, meaning virtually no installation. It took me less than 2 minutes to convert my faucets to push-in faucets. They can also be set up and set down to save space and positioned on the side. (left or right). Otherwise, more space is required for the inlet and outlet hose. I couldn't get the TDS below 127. My unfiltered tap water shows 110. I figured with 4 filters it should be under 50 TDS. If support reads…

Yes, it looks great, but don't worry.

Probably the biggest problem is the severe lack of information about this item, either on the general site they host or specifically in Revain's comments section. I spent a decent amount of extra money on fittings based on the measurements given in the comments. Why? Because their website doesn't even list the IMPORTANT things to know about it. prostate cancer patient. Not that I've ever seen it work. NO. The stupid little white things that go in the ports do NOT come out, even though the…

I am 100% thrilled with this purchase!

I absolutely love this water filtration system. I spent over 20 hours looking for water filtration systems that were unsuitable for my space and/or filtered out nothing but chlorine. This compact PureDrop CUW4 significantly reduces everything but fluoride. (I hate that my city decided to add fluoride to its water supply at no taxpayer expense). I-Spring system from the start because I was impressed with the company. I love that it's a family business and every time I called with questions to…
