Which bottom tank for the zazen Alkaline Water System should I choose?

Which bottom tank for the zazen Alkaline Water System should I choose?
All zazen Alkaline Water System plastic tanks, seals and taps are BPA & BPS free. We use ABS Plastics (which do not use the Bisphenol chemicals in the production to harden the plastic). This has been the case since zazen Water began in 2007 and we released the Glass Bottom Tank as as option in 2013 simply because many customers were asking for it.
Our Glass Tanks and all parts of the zazen Alkaline Water System are manufactured in Korea (no part comes from China like many of the cheaper options on the market) which means our quality is guaranteed and assured.
Whichever bottom tank you decide to purchase, you can rest assured knowing that you and your family will be enjoying delicious, nourishing alkaline mineral water that hydrates immediately at a cellular level!

Amazing service!
I love my Zazen water system, so when I accidentally cracked my glass bottom I wanted it replaced immediately as I can’t stand drinking tap water!! The team at Zazen were fantastic to deal with & had my new one delivered to me very quickly. Thank you!

Fresh Water
Have been using zazen for a few years now ... the water always tastes fresh...decided on the glass bottom tank as it works well in our high humidity weather!
Very happy
