Micromax Replacement Filters
Fidelity Water Systems® Original Replacements
The Ionics® MicroMax™ 5000 & 5500 models are manufactured by CUNO/Water Factory Systems and accept the standard SQC filters.
CUNO/Water Factory Systems manufactures proprietary filters for Ionics® MicroMax™ 6000 & 6500 models. When it is time to replace the membrane in the 6000/6500 model, we recommend retrofitting the proprietary head assembly with the WFS SQC head assembly that accepts the standard size SQC filters or 5000/5500 filters.
