Electronic air cleaner in Santa Rosa

It was a simple service call at the end of the day today, but  I found something really neat that I wanted to share. I have never seen an air filter this old that was this advanced. Of course, modern air filters like this are more effective, but for its age it is really impressive. I love finding things like this.
