All standard size units are interchangeable with all standard size filters. So, if you purchased a standard size HealthMate® and would like to upgrade to a standard size HealthMate Plus®, simply purchase a replacement HealthMate Plus® filter.
When ordering your replacement filter, please ensure you have selected the correct size and type, before confirming your order as there may be a restocking fee for returning filters that are ordered incorrectly.
