Replacement Recommendation
Prime Water Ionizers will notify you when it’s time to change the filter, so you never have to guess. For most households, replacement is required roughly once per year, depending on water usage and source quality.
Combine your Prime Ionizer with the PRIME Faucet (for undercounter installation) and the PRIME Replacement Filters to enjoy the highest quality alkaline water – day after day.
1) How often should I replace the filter?
On average, the filter should be replaced after 3,000 liters of water have passed through it. Depending on your local water quality and daily usage, this usually means about once per year.
2) How will I know when it’s time to change the filter?
You don’t have to guess. All Prime Water Ionizers are equipped with a digital indicator that notifies you when the filter has reached the end of its life.
3) What makes this filter different from regular carbon filters?
This filter is made with premium coconut shell carbon from Kuraray (Japan) and contains Biostone ceramic balls with tourmaline crystals. Together, they remove impurities, improve pH balance, and emit natural Far Infra-Red (FIR) energy for enhanced hydration.
4) Does the filter protect against bacteria?
Yes. The activated carbon is impregnated with silver, which prevents bacterial growth inside the filter and keeps the ionizer mechanism clean.
5) Is it compatible with all Prime Water Ionizers?
Yes. The PRIME Replacement Activated Carbon Filter 1 is designed to fit any Prime Water Ionizer, whether it’s a countertop or an undercounter model.
