I have the OxyQuantum LED UV/Ozone unit installed on the supply side of my indoor unit and the MicroPower Guard Filter installed on the return side. http://www.dugganheatingac.com/indoor-air-quality/
A place out of Augusta put it in for me yesterday. If you want, I can give you an update on how it works in a month or so before you pull the trigger on purchasing something, being that they are not cheap and are a considerable investment.
One not of caution, it has to be placed smartly, as the UV will literally disintegrate plastic within a year or so. In my case, the return ducts were flex-ducts attached straight to the return box of the air handler and the tech said that if he put it there, those ducts would be gone in a year or less. My supply side was a metal distro-box with a metal manifold, hence he put it on the supply side. He turned it on and showed me it working and it was BRIGHT and shot all the way up the fan and to the coils. You also have to make sure any wiring is out of the way of the light. The unit is powered via relay that turns on only when the fan is operating. The unit draws 44 watts.
The MicroPower guard filter slides right into a slot on the air handler that was literally made for that filter. It has a sturdy aluminum frame that holds the filter media. The media is replaced every three months and draws 2 watts of power. The tech told me the only benefit to having traditional filters in the returns is to have less dust in the return ducts, and even then to just use the cheapest filters available. I will update you on the performance of the system come this spring when God uses pollen to punish mankind for it's sins.
