Hey, Ken.

Thanks for the tip.

Thanks for posting those links.
I’m going to pull the fuse out of my Phenomenal Aire bipolar ionization unit today and see if there is any change in the VOC levels in my encapsulated crawl space. (I...

Thanks for the post. ROSs and limited peer-reviewed research are a concern.

I wonder if anyone has hooked up a damper on a fresh air intake and tied that in with an outdoor air quality sensor. ...

Hey, Kevin.

We never actually saw any growth on the coils of the Lennox indoor unit. We had them cleaned several times by HVAC techs and I cleaned them several times with ProGreen (Diversitech)...

Kevin,
Thanks for the reply.

Unfortunately, I can't move the UV-C lamp to the return side without cooking the media filter. (The media filter is directly above the coil, which is where we want...

A little searching and I see that Phenomenal Aire also sells a duct-mounted ion meter under its commercial product. (I can't post a link due to forum...

Thanks for the great info and links, Randy.

I look forward to your post on VOCs. Will you be posting here or on a blog?

Thanks, Randy.

Is the PID meter useful for tracking VOC sources (like hound dogging) or does it take more of an ambient room sample over time? What’s the make of the PID meter you’re using?

I...

Using a TriField Meter (Model 100XE), magnetic and electrical fields drop off to nothing (or no more than ambient fields) at around 15 inches from the back of the Phenomenal Aire Series R 6.0.
