Bottling Process
Finken Aqua Systems bottled drinking water is packaged under the strict guidelines of federal regulations. Our extensive analysis of each bottle ensures consistent quality in every drop.
Multiple Stage Purification
Before being washed and sanitized, the bottles must first pass an abrasive chemical inspection. Any bottles that fail are immediately removed from use. The water undergoes a four-stage filtration process, including ozone disinfecting, before it is bottled, sealed, and capped to ensure maximum purity.
Why Returnable Bottles?
We choose returnable bottles because we believe in sustainability and keeping as much plastic from entering landfills as possible. Plus, our thorough purification process makes recycled bottles just as clean as new.

“We had our reverse osmosis water system and a new water softener installed in Feb 2018. We can’t be happier! It’s a complete night and day difference in how our water tastes and how good our ice is (I don’t buy ice any more!) Our skin feels awesome after showering and our laundry looks better too! I so happy with Finken I called them back today to look into a tankless water heater! Thanks Finken!”
