Does anyone have any experience with one of these duct mounted devices. The
Fresh Air model by Quest International was originally developed as a Free
Standing Unit, and the independent research of this device actually showed
high levels of Ozone production (.05 ppm). The one I am questioning about
is the duct mounted model called the Ductworx or something like that. It is
supposed to be mounted in the supply plenum, and only produces negligible
amounts of O3.
I still believe that the Sanuvox R1500-4000 is the best residential UV
system on the market. What I liked about this other device is that it
supposedly disperses products that actually clean objects in the conditioned
air, downstream duct work and insulation, rather than what just enters the
I have read the Kansas State tests and believe this claim of theirs, but I
can find no conclusive evidence of this duct mounted device producing or not
producing toxic levels of Ozone. I have seen and believe the other testing
of their free standing device does produce too much ozone.
I have spent the last two days researching this and cannot find anything.
Does anyone else have anything to contribute to this. PLEASE NO SALES
They claim to use a UVX spectrum of UV light. There is no such spectrum.
It is a luminescence tester, or a Homogenized Radiation System operating in
the 360 - 380 nm, that is all I could find out about other than some vacuum
cleaner claims to use it to sanitize floors ( more BS I am sure)
I had the salesmen in my office the other day, and I like the product, but
do not want to install it if it is a high ozone producing device. They are
wholesaling for about $350. He was also pushing a device called the Power
Shaver, it reduces energy consumption of any motor (not VS) in your home and
can be hooked up to your electrical panel and it will be effective at
reducing the energy consumption of any motor in your home, i.e. blower
motors, washing machines, fans. I have done no research on it yet, but saw
the demonstration and I'll be damned if it didn't drop consumption by about
30%. It might be snake oil, I am not sure yet.
By the way, what I have discovered (or rather reconfirmed) is that all UV
stick lights are ONLY effective at object cleaning, do not air purify, and
they ALL are pretty much the same. They do not increase efficiency, they
reduce mold and bacteria growth on what ever they are in constant contact
with. A filter keeps your friggin coil clean.
Sanuvox by the way has a couple of really good pps' and videos about it's
products in the contractor sections of their site, I recommend them to be
