When I had a new gas furnace installed, the salespeople insisted that the Guardian PHI cell was the greatest. Now after 3 years the lamp must supposedly be replaced (several hundred bucks). They say it produces "Hydro Peroxides", or hydrogen peroxide. Another recent post said a power supply burned out - well that's not uncommon and doesn't have much to do with the actual PHI cell. Mine has been working 24/7 for 3 years.
The RGF web site has no believable studies or certified lab confirmation on these products, yet they claim that their PHI and REME cells will kill any virus on contact.
After 3 years of use, I can't confirm or deny that there has been any air quality improvement or diseases prevented. The only thing I have to go on is their sales literature and slick u-toob videos, and they really don't inspire the discriminating mind to say the least. And, nobody ever seems to be home at the RGF headquarters - not impressed by that.
I'm familiar with high power UV lamps for water purification. Is this product simply a UV lamp? Or a weak ozone generator? Wouldn't I be better off putting the 300.00 for a new lamp towards an electronic air cleaner (yes, I know they have to be cleaned regularly). Without independent lab certification, how are we supposed to believe all these amazing claims?
