If installed on the supply side, after the filter, and after the furnace heats the air - wouldn't the built in fan introduce dust and cold air in the supply?

The fan draws air from within the duct through the moist evaporator panel and back into the duct. There is no room air pulled in through this action.

Best way to use is have fan sucking air through the filter. Fan should pull air through filter and exhaust "scrubbed" air outside the room/area where filter is located. Keep the length/run of duct as short and straight as possible. Seal all connections between filter, fan and ducting with duct tape to avoid any unfiltered air being exhausted.

No it does not. The fan is either running all the time or running when the a/c or furnace is on.

I didn't use it for a filter,I used it for a inline A.C.duct that wasn't blowing hard enough. Even then the fan was not strong enough to make a noticeable differance,will try larger fan.

The humidifier only runs when the furnace fan is running during the heating cycle. During the central air cooling cycle, the water supply to the humidifier needs to be shut off and bypass air damper closed as there is no need for humidification in this cycle. However the electrical connections were done by the contractor and am not aware of these details.

The booster fan runs continuously when it is turned on. In my situation, having continuous operation when my furnace wasn't running created a negative pressure on my HVAC ductwork, drawing in cold air via my air-to-air exchange system (defeated the whole purpose of my purchase). If this unit would have cycled on/off with my furnace, I would probably still have it (I returned it).

I have mine on the wall in a similar insulated oversize double garage/shop. I use it in conjunction with a ceiling dust filter to circulate the air. It was 32 or so yesterday and it warmed the shop to about 60+ in a couple of hours. I think good circulation helps since I have a 10 foot ceiling. My filter instructions for good circulation suggest installation on one side blowing to force the air around in a circle.

air flow through the filter is not restricted when the filter is clean. just remember to clean it every 3 to 4 days to prevent dust build-up

I. Installed in the cold air return just before the air filter......I have no problem.

Yes, we just purchased a home that had been "winterized" which means no airflow for weeks. It smelled a little musty, especially in the basement. I turned the central AC fans on and pointed this at the air intake with fan on high and ozone on low. Next morning when I returned to check on it the entire house smelled absolutely clean.

Fans are always better than just a heat sink. You just have to keep an eye on the dust collection of your unit. If the fan gets clogged, it will freeze up, and then burn up. It happened to me once...

I don't think that this A/C unit will operate this way, but I'm not 100% certain about this. I believe that the outside and inside air can't mix, but I'm a little unsure about this, since there is a filter of some sort. (Our filter light came on after a few weeks of use, by the way, but I haven't yet figured out how to change this or even if this is critical.)I think that the "fan only" mode merely draws room air through the unit without any cooling.

I've never used the filter without the dust cover but I can say that the unit does restrict air flow somewhat. I have in inline 400 cfm fan attached to the filter and there is some slight blow back with the filter attached...I use the filter to mask odor and it does an excellent job and I have no complaints! If your Hyper Fan pushes more than 400 cfm then I wouldn't worry about the resistance. Hope this helps!

It should be installed somewhere inbetween the exaust fan and the thing you see outside. I bought thiss to stop cold air from coming into the dryer. Works better than the vents that are normaly outside which you would keep. If you really want to stop the air completely (which I did) then you'll have to doctor this up a little bit. A Flood Light doesn't even penitrate mine after. It works great now

The filter is not connected to the electrical output--it just filters the air as it is brought through the machine from the fan. It works quite well.

I put the fan in the middle directly above the amplifier it cools. The area above the fan is clear of obstructions ensuring that the fan works efficiently.

I set it up to push through the filter and it does work. There was an initial puff of loose activated charcoal dust, but only when I turned the fan on for the first time.
