We are planning to buy Geyser stationary filter, and we need your help to decide which one is best for us. We live in the area where PPM from tap is ~220, and dH is ~12-14°. We love the practicality and capacity/economy of ECO and ECO MAX filter: small, efficient, 1 filter, easy to replace (once a year), and that's it. On the other hand BIO 321/331 filter system seems like a more efficient filter, more space, more care about filter regeneration/replacement, etc.
Considering that my wife and I want the best water for drinking possible, we have a few questions for you, and of course every critic/suggestion from your side is more than welcome:
1. How ECO and ECO Max compare in terms of water filtration efficacy? What about filter changing frequency?
2. Are filters interchangeable? Housing should be the same/identical?
3. Could/should ECO/ECO Max be regenerated?
5. How ECO/ECO Max compare to BIO 321/331 in terms of water filtration efficacy and what are the exact differences?
6. Does Aragon 2 BIO could/should be regenerated and/or cleaned from mechanical particles and how often?
7. Which one (in our case) from all 4 above mentioned wold you chose and why???
P.S. We are planning a baby too...
Thank you upfront for your time and expertise! Cheers
