Thoughts on the REME HALO® In-Duct Air Purifier
Is this a safe product? I found some articles describing how the underlying technology was being used to sterilize medical equipment, but I could not find any independent evaluations that found it acceptable for air purification.
A family member has suggested that we all buy one of these things, and I haven’t been able to find enough information to determine if this good advice.

Looks to be similar to the many plasma based air purifiers touted out there. Basically just pass high voltage between two electrodes to generate a bit of ozone. They don't do much "purification" any real ozone production would be pretty bad for indoor air quality. It does help with smells a bit, these are typically touted for dealing with indoor smoking or pet smells.
It also don't do much real filtering, my wall mount has it and I find no difference running it during allergy season.
No idea why that device would be effective, or wanted.
Based on the description I thought it might be an electrostatic precipitator, but that doesn't look like one.
Aprilair makes one which uses high voltage to charge a series of plates, one neg, the other positive. Does a good job of attracting oil/smoke/particles to it. It does have to be cleaned periodically, but looks pretty simple, shouldn't change flow/pressure much compared to a high MERV filter.
Thanks, guys. Your comments confirm my suspicions about this particular unit.
