A clear next step for older ionizer owners

If you are looking for a filter for an older AlkaViva ionizer, start by identifying your machine and the original filter. Check the older-model filter directory for current listings and availability, which can vary by product. An H2 upgrade is an optional new-machine path; it does not mean putting an H2 filter into an older model.

The Delphi H2 is an undersink model. Athena 9 H2 and Athena 7 H2 are countertop models. These are three different current ionizers, not universal replacements for every older machine. Choose based on the installation you want, then confirm your old model and setup with AlkaViva before ordering.

H2 Series replacement filters are designed for H2 Series machines. Do not order one for an older ionizer without checking compatibility with AlkaViva. If you are unsure what you own, have the machine's model label or a photo ready so a specialist can help identify it.

Use the older-model guides below to find the filter name and source listing you recognize. They preserve the distinction between legacy cartridges and the separate H2 filter system, and provide a practical route to comparing a new ionizer.
