Neither do I also find any damages or scratches on any part of the water filter. 

After opening it and looking at the quality of the filter I was impressed. 

I was already contemplating on returning the water filter until I found out it had quick plastic connectors as well as plastic tubing. 

Brought out the device, cut it perfectly, and pressed hard when seating the hose and it seems to have the dealer just fine. 

I can easily move the filter a bit if I need to, I left the tubing the factory length. 

I left the house intact as I have read through different reviews stating how important it could be for easy service in the future. 

You will also find the serial number as well as other essential info of the water filter at the bottom of the package. 

Make sure you take a picture of the water filter’s bottom as soon as you inbox the product.

I also discovered that the brands include a user’s manual with the package. 

The manual contains some certain sets of instructions as well as a step-by-step guide on how to put the water filter in place. 

For instance, I got to know by reading the user manual that it is essential to change the filter cartridges every month even if the indicator is not showing red as many users brag about the indicator still being blue one and a half year in.

Sometimes, the process might require you to install a dedicated faucet that you may not like.

There was a water leak around the female adapter to the cold water shut off valve.

I had to put some Teflon tape and tighten the adapter using a wrench. 

Meanwhile, it is important to know that you must press the black tubing all the way in to seal. 

The black tubing needs to be pressed in until you feel it often stop about ¼”. 

Then, you press a bit more and it will slide past the seal and tube grippers that hold it in place.

3. Reduced Dissolved Solids By Less Than 10% 

I bought this exact filter at one of the big home improvement stores and mounted it with a dedicated drinking water faucet in my kitchen. 

I faced no challenges during the installation processes and the filter was leak-free.

It also flowed a good amount of water. 

Unfortunately, the water tasted the same and the filter reduced the dissolved solids from 520 ppm to 485 ppm. 

With the expensive rate of the filter, I expected a significant improvement but was disappointed. 

4. Leaks 

Some users have complained about the Kube water filter leaking. 

One of the users narrated his experience of having installed the device halfway and later figured out that they did not include the elbow fittings needed to connect the filter to the water supply tubes. 

The installation was attempted the following day with everything connected and then 3 of the four fittings promptly. 

Unfortunately, the water leaked everywhere in the kitchen immediately; the water supply was turned on. 

Each connection was jiggled at least to reduce the leakage level and was left with a slow dripping leak from the main water supply line fitting. 

5. Taste like Tap

Even though the water filter cleans your unhealthy water and erases the awful smell in it, many users still believe the water filter tastes like a tap. 

However, it doesn’t mean the water taste is too bad, but if you care about the taste of your water you might consider going for another model.
