First film seems to be gone. So I found some more films that say more and go deeper into the problem.

Atmospheric Water Generators
Atmospheric Water Generators? [ How clean is the air in our homes?]
It is a humidity and temperature driven machine that makes water from air. This means the machine generates water from the humidity in the air. Ideally, the humidity level should be at least 35% or above to achieve the machines maximum performance. In regions with lower humidity levels, the machine will manufacture pure drinking water at a lesser capacity than in regions with high levels of humidity. The period of time to achieve optimal water production is directly related to humidity. As an example, in a household environment, higher levels of humidity tends to be around kitchens or any spacious room.
Drinking Water Safety
What (Not) to Drink
# Bottled water is generally safe, but only in sealed, tamper-proof containers. Ask someone at your hotel to recommend a reliable local brand.
# In addition to bottled water, you’ll usually be safe drinking tea, coffee, canned soda and juice, beer, wine, and other alcoholic drinks.
# Prolonged exposure to higher temperatures will kill many parasites. Drinking from a hot water bottle is slightly safer than drinking untreated cold water.
# You don’t need to drink contaminated water to be exposed; always consider alternate sources of exposure, like the water you use to brush your teeth, or to wash your contact lenses or dentures. Be sure to use bottled, boiled or purified water for these purposes as well.
# Freezing water does not kill bacteria. A margarita on the rocks may sound appealing, but ice cubes present the same problem that tap water does. You can make your own ice if you boil the water first.
# Avoid food that may have been rinsed in contaminated water, such as salad and fresh fruit. For more info, see our article on food safety.
Drinking Water Safety in Emergencies
A disaster may disrupt electricity needed to pump water into the home and/or contaminate your water supply. Unless absolutely certain your water supply is not contaminated, purify all water before using it for drinking, preparing food, brushing teeth, or washing dishes. If the water contains floating material, strain it through a clean cloth before purifying it. Following are methods for ensuring safe water for emergency use.
The Center for Disease Control (CDC) and the Minnesota Department of Health (MDH) recommend that you bring the water to a rolling boil and boil it for at least one minute. Cool before use and don’t contaminate boiled water with dirty utensils, hands or containers. Add a pinch of salt to each quart of boiled water to improve the taste.
