Calcium sulfite in water filters – is it a concern?

Good afternoon Mr. Akgün,

good afternoon Mr. Asenbaum,

Would you please explain to me again how “bad” the calcium sulfite in the filters is, especially considering that we also use plenty of filtered water (without ionization)? How relevant is the amount released compared to other foods containing sulfite (wine, etc.)? Thank you.

With kind regards,

Oliver A

Answer from Karl Heinz Asenbaum about the safety of calcium sulfite

Hello Mr. A.,

There's nothing to worry about in terms of quantity.

I have yet to see any analysis in which the calcium and sulfur content increased due to the calcium sulfite used in almost all water filters. It is a special calcium sulfite ceramic that does not dissolve. If you saw open an old filter, the white ceramic beads are all still there. It is primarily used to remove chlorine and also pulls heavy metals out of the water. It serves not for enrichment with calcium, as some falsely claim.

There are other calcium compounds that are added via a shaft in areas with extremely soft water. In our part of the world this is completely unnecessary.

Additional answer from Yasin Akgün about filters without calcium sulfite

Dear Mr. A.,

If you absolutely do not want to have calcium sulfite in the filter, we have the following solutions, even if I also believe that everything is not an issue and has a purpose, just as it comes standard from the factory:

You can have your filters in the ionizer capped and filter the tap water with a pre-filter. To do this, you would have to send the system to us and go without the water for a week. The pre-filter system would be this: www.aquacentrum.de/shop/wasserfilter-set-aquaphor/
You could replace filter number 1, which contains calcium sulfite, with a variant without calcium sulfite that we specifically requested. However, that only works with this one AquaVolta® EOS Revelation and AquaVolta® EOS Genesis. We can talk about replacing your water ionizer at any time.
