Yes and no again, if you remove the alkali and mineral filter, you get a di system. For that price, I think I can get 5 ro/di 5 stages system.
If you really want to use, it is possible. Ask them for a complete lab analysis of their water. Look out for the heavy metal levels. Since they say alkaline water, you have to look out for the pH and alkalinity. In conclusion, for the price, risks and trouble involved, go get distilled water or ro/di filter
