[...] The installation was very easy. The water filter is for under the sink, which is very practical for me. Also, it is easy to use and to control. The water tastes good. I can taste a difference in water quality. Very pleased with this water filter, and I will keep buying it.

The WaterChef under-sink filtration system has sophisticated monitoring, which is important for determining when to change the cartridge as well as total usage – it can hold up to 1000 gallons of water. And here’s the best part: the filter will successfully remove a variety of dangerous impurities while leaving calcium, magnesium, and potassium alone.

This has been a great addition to my kitchen. No more constant pitcher filling! Install was straightforward. The gasket leaked initially, so we opened up the housing and found there was some grit on the o-ring. Once wiped off, there were no more issues. I look forward to using this system for many years to come.

Under-sink connections of 3/8-in and 1/2-in are compatible with the Express Water. It has a 4-gallon water tank and may be used for up to 6 months before needing to be changed. The best feature about this water filter is that it utilizes UV-C radiation, which is quite effective in destroying hazardous microbes (viruses, bacteria, and parasites).

We get water from a well so we wanted something really good. The UV bulb is a great idea because it'll sterilize the incoming water and remove the bacteria. But the alkaline filter does add some minerals. So, the water isn't totally sterile. It still has those healthy minerals and particles, but none of the bad ones.

There’s a 4-gallon storage tank with a 75-GDP water flow rate. Replacement filters for the APEC water under-sink water filtering system are available in nearly all sizes (making it very convenient for the process of replacing spare parts when worn). With a 99 percent efficiency, the filter can remove chlorine, fluoride, arsenic, smells, and unpleasant tastes.

This unit has all the bells and whistles. It is easy to install and the water tastes great. The unit exceeds my expectations. I had an issue with the tank and their Service Department was very helpful

Strong enough to filter out heavy metals and other potentially harmful sediments while preserving potassium, calcium, sodium, and magnesium. The Water Drop under-sink water filtration system is available in a variety of water capacity capacities. It is also constructed with a twist and lock method for easy replacement.

Easy install with no issues so far. You can instantly tell water quality is better. Also, no hard water spots on black quartz sink..

Built on a strong base that ensures no leaks. The Frizzlife water filtration system likewise uses a twist and lock design, so replacing a worn filter takes only 3 seconds. Moreover, the water flow rate is around 2 GPM.

Beyond pleased with this water filter. We live in a city that has the worst water quality and after connecting this filter to our sink our food and drinks taste 100x better. I hight recommend the fizz water filter.

Capable of removing up to 1000 contaminants with a 99 percent success rate. The Bluonics under-sink filter has a 5-stage water filtration system, incorporating carbon filtration as one of the stages. Apart from that, it can be used to eliminate chlorine, fluoride, arsenic, salt, and other contaminants.

Didn't take long to hook it up. If your any kind of a handy man you wouldn't have any issues setting this up. After you purge the system and follow the instructions by far the cleanest and purist water I have ever drank. Good buy!!!

The non-electric RKIN water filtering device is incredibly silent when in use. In the meanwhile, reverse osmosis is being utilized to filter the water. It also includes AlcaPure for an alkaline pH and OnliPure for a TDS result of zero.

Easy to install , it’s lightweight and have filter cartridges to change with ease. Other RO systems are heavy and have casing to remove the filters and change the o-rings. It can be messy to change. I like the quick connect plumbing on my new RO system. It can be installed in little over an hour.

Filter replacement is simple to install and disassemble. The Aquasana is designed with the environment in mind – sure, you can save money by switching to a water filtering system instead of buying bottled water. Furthermore, the efficacy rate of around 77 pollutants may be eliminated.

i did not want to drill a hole in my granite. i went with this new one per the water consultant and am so glad i did. My water is great! best decision of my life.

Installation is quick and uncomplicated, taking approximately 15 minutes. The Hydroviv water filtration system incorporates a filter that improves the flavor of the water. In terms of the long filter replacement period, it is recommended that it be replaced every 6 months to maintain a robust filtration process.

Easy install and great tasting water! I threw out the under counter reverse osmosis system that this replaced...looking forward to changing one filter every 6 months as opposed to five!
