Quick 1 1/2 minute video of how easy it is to wash and clean the Aireshield with a rag and soap and water or rubbing alcohol.
I have powered off and removed the Aireshield from the HVAC unit as well as the nylon mesh prefilter. It is moderately dirty, but easy to wipe off and reuse. Just be careful with the sharp pins. After removing the powerbox the Aireshield can be cleaned in the sink if you wish to do it that way, just be sure to remove the powerbox which includes the electronic parts.
