One of the main benefits of having this job is learning about new, innovative products all the time. The Kara Pure 2 is one of those. In the past few years, we have covered a whole host of water filtration systems here. Most of them require you to fill their water reservoir to use them. The Kara Pure 2 is an air to alkaline water generator. It generates its own water from the air and filters it. The good folks behind it were kind enough to send us one to test. Let’s see what was included:
The Kara Pure 2 was a bit larger than we expected, but we had not tested these AWG machines in the past. Our item weighed just under 82 lb according to our scale. It came very well packed. The unit is pretty simple to use. It has a button that you can push to get some water. There is also a touchscreen display that gives you access to various settings. For example, you can get hot, room-temperature, or cold water with a press. The temperature for hot and cold water is adjustable.
Our unit came with preinstalled filters. It also has a UV light to ensure your water is clean. Before getting started, we removed the protective foam inserts from inside the machine. To access that area, you will have to use one of the included keys. The Kara Pure 2 is ready to go out of the box. Just turn it on and wait for it to collect some water. The guide suggested it could take 48 hours to generate water, but our unit reached 100% in 23 hours.
The machine has a 7-inch touchscreen display. Once you turn it on, it tells you that you’ll need to prime the filters. The idea is to run enough water through the system to ensure you only get clean water. You can monitor the humidity and temperature through the display. It is also possible to calibrate the tank sensor or reset the unit entirely.
Our Kara Pure 2 walked us through the priming process. Once that was done, we waited about 12 more hours to get to 100% again. You can easily see the filter status on the display, so you will know when you need to change your filter. It is possible to turn off the hot water function if you prefer. The unit lets you change the temperature for hot and cold water. For cold water, you get a range of 45°F to 70°F. Hot water goes from 150°F to 190°F. We used a FLIR thermal camera to read the temperature of the water and got readings within 10°F of what was advertised. The water was hot enough to enjoy a cup of tea without using a microwave oven. This machine doesn’t have a refrigerator, so you shouldn’t expect freezing cold water out of it.
We opened the back of the machine to thoroughly inspect it. The tank inside is removable. Once you open it, you can see the sensor that gives you readings on how much water has been collected. You get instructions on the side for changing the filters. There are also tubes that we assume are removable if you need to perform repairs. This air to water generator has an air filter to make sure you get the highest quality water possible.
We tested the pH of the water that came out of the machine and found it in the 9.62 to 9.80 range, which means it is alkaline. As for the temperature, we could not see any major difference between cold and room temperature but the weather is cold this time of the year, so the experience is probably different in warmer conditions. When you press the button, a light turns on, so you can watch your drink being poured in a dark environment.
Kara Pure 2 not only generates clean water but also adds minerals to make it healthier for you. It generates 10 L of water every day once you complete the filter priming process. The unit is heavy enough not to tip over easily. It was about the same size as our fancy trash can but just a bit longer, so it fits even in the smallest kitchens. You will just want to make sure you don’t block the vents. If you plan to gift this to someone, you will want to use the Drain function to make sure the machine is empty before shipping.
During our tests, we got to update the firmware twice, which shows the team is working all the time to add more features. You simply have to connect the machine to your WiFi network to get started. Resetting the machine was very straightforward as well. While you can technically skip priming the filters, you will get notifications to do so as you start using the machine.
Overall, we found the Kara Pure 2 to be easy to use. We just plugged it in, reset the sensor, and it started making water. It doesn’t make a whole lot of noise and generates water even faster than advertised. We managed to get to 100% in 23 and 18 hours in our first two tries. The pre-filter, ultrafiltration, and alkaline mineral filter last for 3000 L, which should be about 4 months. Even if you live in dry areas, like Arizona, you will still be able to use this machine to generate clean water. This invention could be a lifesaver in areas that have no easy access to clean water or any facilities to easily produce it.
