Well, you learn something new everyday. That is for sure when you work at The Allergy Store.

Today, we had an interesting customer call.  The pleated, disposable air conditioning filters go are starting to crumble. 

For as many years as we have been selling pleated, disposable filters, I have never heard of the filtering media crumbling.  We discussed the situation at length, so that when I phoned our manufacturer, I could give him a full report. 

When I spoke with the manufacturer, he was also stumped.  However, he asked me one important question, “Does she have an ultra-violet light installed so that it is shining on the filter media area?”   I had not thought to ask her this question.  He went on to explain that the filter media in the disposable electrostatic filters is 100% polyester.  He says they use no cotton or wool fibers in the material as they do not want to encourage mold growth on the filter media. 

However, the polyester can be destroyed by exposure to intense ultra violet light.

I phoned the customer back to ask if she had UV lights in the area of the filters and she told me “Yes”.  The filters were installed with a UV light shining directly on them.

Mystery solved!  She is moving the ultraviolet light so that it will not shine on the filters.

We all learned something.  As well as our custom made, pleated electrostatic disposable filters are made, they can’t stand up to continuous ultra violet light.

Wishing you the best of health
