Those water filters...

These two water filters are used in my office. Usually, I didn't notice the filters, just tapped on the tank, fills the bottle and set it back in my chair. But in a break time, I just saw a simple but excellent design brilliance. In the first filter, we have to use our two hands for proper water filling in our glass but in the second filter, we can use it with only one hand. I'll show three more pics to get that clearly

 

Here you can see clearly that by using a second filter (blue colour) we can get water by using only one hand and also this filter can be hung on the wall. So that we can get water without bending our bodies. That's also a great design excellency I noticed
