When to Replace an AER Filter

replace-aer-filter-question

AER Filters are used in automatic endoscope reprocessing equipment. To properly reprocess and clean the endoscope these filters must be free flowing and the best practice to ensure that they operate at the highest efficiency is to follow the manufacturers recommended maintenance schedules for replacement of these filters. Failure to perform required maintenance may result in injury or death to the operator or patient so it's extremely important that you refer to your Medivators / Cantel user manual and follow their specific recommendations as the information below is extremely generalized.

AER filters are located outside the AER and technically, the timing for replacement of the filters has to do with the water pressure coming out of them. The water pressure should be at 40 psi or above but follow the manufacturers recommendations for replacement as there are many different types and models that may have different specifications. But waiting for the pressures to drop below the recommended levels is not the best practice and does not promote the long life of your investment well.

A better practice is to keep several Medivators AER Filter replacements (Cantel AER Filter replacements) on hand and replace them at least every three months (or whatever time frame the Medivators endoscopic reprocessing equipment user manual recommends) even if the pressure is still above 40 psi.

The filters in the pre-filters housing can be changed every three to six months but check the manufacturers recommendations for your specific unit to be sure that you're taking care of your machine properly so it can last as long as possible, operate at the most efficient levels and keep your expenses as low as possible.
