Why Water Matters for Your Body
Water makes up about 60% of your body and is vital for every cell and function ​​​​​​  ​​  ​​  ​​. Drinking enough pure water-about 2 liters (8–10 cups) daily-keeps you hydrated, energized, and healthy ​​  ​​.
​​​
The Hidden Risks in Drinking Water
Even clear tap water can contain hidden contaminants like pharmaceuticals and 'forever chemicals' (PFAS), linked to cancer and hormonal issues. Nearly half of U.S. tap water is affected. A global study also reveals widespread antibiotic pollution in rivers, underscoring the urgent need for better water management and safer choices.  FOX NewsCNN Health

Why We Created 1THE Water Filter
We all know how essential clean water is to our health and our lives.
But for many, owning a water purifier still feels out of reach-High prices, complicated installation, and expensive maintenance too often stand in the way, even for those who truly understand the importance of safe water.

We believed everyone deserves access to pure, healthy water-without barriers.
That’s why we spent years researching and developing a solution that is affordable for all, simple enough for anyone to install, and simple to maintain at a low cost.

The result? The two models of 1THE Water Filter: designed so that anyone, anywhere, can enjoy clean, safe water-without worry or hassle. 
Because clean & healthy water should be simple, accessible, and for everyone.

I strongly recommend the product. This product has a good quality and easy to set up. We are able to drink safe and clean water at home at once. It is convenient to change and manage the filters unlike making an appointment with technician.

Great Tasting Water and easy to install and maintain.

I purchased this unit because I needed a good water filter in my kitchen. I had looked at several stores and this seemed to be a really good value for all you get. You receive everything you need to install and use this unit. This includes the faucet (can be 70 dollars alone). A three stage filter systems (these can be really expensive on their own) The stages help remove just about all unwanted particles and contaminants from your water giving you really fresh and clean tasting water. It took me about 30 minutes to completely install this unit. I already had a place on my sink for the faucet but it would not take long to drill a hole for it. This unit comes with a really easy to follow set of instructions to walk you through the entire install process.The filters easily snap on and are color coded so you will have no worries about installing them. The faucet is really nice and not only has a high rise design but also can be turned on and off by the turn of a knob. You do not have to hold the knob to keep the water on like some other units. This has been a really great addition to my kitchen as our water is not always reliable and this allows us to make sure we always have clean and fresh drinking water. I was really impressed by the ease of installation and how well this unit works. The unit also comes with an app and alarm to let you know when the filters need changing and there is a shut off valve included that lets you shut off the water flow easily for changing filters. I have included as many pictures as I could to show what you get and how it looks. If this was helpful please click yes below.

Absolutely amazing! The water is crisp, and I feel good knowing it’s mineral-enriched. My family is drinking more water now.

This filter is fantastic! The installation was simple, and now my whole family enjoys mineral-rich water every day. Excellent product!

It fits perfectly inside the sink, so it doesn’t take up any space, and I like that I can use water while cooking. Installation wasn’t difficult, either. I’ll make good use of it!

Perfect for chlorine smelling municipal water
Reviewed in the United States on October 8, 2018

We have been looking for an under the sink filter system for awhile on Amazon , what drew us to this filter system out of other ones that we had looked at is this has less parts and it's easy to install and you can download the app on your phone so you can keep track of your filters. We have horrible municipal water, it smells so bad from chlorine that some days it burns your eyes and this made our water not only not smell but it actually tastes like the gallons of purified water that we were buying every week to drink. For us to install this we had to drill a 1/4" hole through our old cast iron farmhouse sink and we also had to buy a different valve than the one that this kit comes with, the kit come with a 1/2" valve but we have 3/8" pipes so we bought one on Amazon for less than $12 ( JG Speedfit ASVPP1LF 3/8-Inch by 3/8-Inch by 1/4-Inch Angle Stop Adapter Valve ) and from start to finish it was about a 20 minute install and it matches perfectly with my sink faucet and sprayer , I was also surprised at how fast the water streams out of this, I can fill a gallon jug in 1 minute, most systems seem to just trickle out so I was extremely happy with the pressure of this system

This is a really beautiful and useful piece of kitchen hardware. The filters were easy install, I had this faucet installed and running in a couple of hours. The detachable spray head is GREAT for cleaning the sink from all angles, and the spray is conveniently controlled by a button right on the spray head. It retracts easy and seats itself with precision.Using the lever on the right side of the faucet, you can use either tap water or filtered water. I love this feature because if you're just cleaning up, you don't want to waste the filter, but if you are using the water to fill a cook pot or for drinking, you can select the filtered water feature. Therefore, the filters won't have to be changed as often as fixed filtration systems where you are unable to choose the function.In addition to being useful, this faucet is quite elegant and graceful looking. It adds a touch of luxury to my sink area--it really dresses up my kitchen. The detachable spray head is marvelously convenient, and I like being able to have filtered water or plain tap water at my discretion. Five stars!
