View Full Version : uv light?????????
could anyone help me with the decision between Sterile-Air, Carrier or Honeywell systems? or are there any other ones? do i have to worry about ozone with any of the systems?
Don't waste your money on UV!! They do not kill mold in the air!

Check out the web sight for Sanuvox.

so many gizmos in HVAC, so many indeed.
save your money.
get a decent MERV 10 filter for the return path, ventilate, and keep tabs on the humidity level.

TRC Sterile-Air has a decent system if you just want bulbs. Proper placement is important. Beware that alot of yesterdays drain pans under the coil are of a plastic that doesn't have a uv inhibitor in it and the uvgi light might degradate the coil box. I would also check maintenance requirements for the bulb and cost.
And DRK UVGI does kill airbore mold spores if the residance time across the bulbs is correct. A single set of bulbs side by side has its advantages but the contact time isn't there for mold spores. They take more residences time in the light.
With the lights I would also suggest incresing your filtration between a 4 in Merv 8 to a 4 in Merv 12 filter. The increase in size of the filter will help control the pressure drop across it for the higher filtration.
thank you genesis
i have a new house (8 months) but will still check to make sure everything is compatible.
this is a stupid question but what is a Merv filter. is it just another filter that i slip in the spot of my existing filter or is it something that i have to get installed? i just have a regular cheap filter (fiborglass?)
i was told not to use the pleated filters because they restrict air flow or make the blower work harder.
Gen You are wright! But why would you want to put three, four, five UV lights in line for less than perfect performance. A service contract will be money well spent! Not on UV

MERV, or Minimum Efficiency Reporting Value, is a number from 1 to 16 that is relative to an air filter’s efficiency. The higher the MERV, the more efficient the air filter is at removing particles. At the lower end of the efficiency spectrum a fiberglass panel filter may have a MERV of 4 or 5. At the higher end, a MERV 14 filter is typically the filter of choice for critical areas of a hospital (to prevent transfer of bacteria and infectious diseases). Higher MERV filters are also capable of removing higher quantities of extremely small contaminant (particles as small as 1/300 the diameter of a human hair). A higher MERV creates more resistance to airflow because the filter media becomes denser as efficiency increases. For the cleanest air, a user should select the highest MERV filter that their unit is capable of forcing air through based on the limit of the unit’s fan power.
Most filters become more efficient as the filter is used in the system. Care should be taken when considering filters that incorporate an electrostatic charge. Although offering a reasonable MERV value these filters will actually drop in efficiency as the filter loads with contaminant. A number of electrostatic filters are presently being offered for residential as well as the commercial/industrial applications. Refer to the filter packaging or literature to determine if the filter you are purchasing relies on an electrostatic charge to boost its MERV. If it does, request that the manufacturer provide you with the “discharged MERV” for the filter to determine its actual in-use performance. A standard pleated filter is around a merv 6. If you install a 4 in thick filter you can increase the merv rating that you can use with out causing a pressure drop that will effect your system.

You've probably already bought UV lights without thinking about photocatalytic oxidation (PCO) options. You might want to consider Genesis Air, Quest Commercial DuctwoRx using RCI Cell technology, or other PCO systems. Examine their pluses and minuses, keeping in mind that some, like RCI Cell technology, are getting results not based upon dwell time exposure of the pathogen to the UV light, but upon interaction with the friendly oxidizers generated by the PCO actions.

^ "poof",lol...if only mold could be "deleted" so simply.

what did lab guy do to get eliminated in that fashion?
...make fun of FOX news or something?
