I've been doing this for years. I thought of it myself. I put mine on the back of the fan, taping it on to seal every bit of leakage. I use duck tape.

You should consider the motor being used in the fan - if it is a sealed motor it produces no ozone, if not it will. In the case of this example fan unit - I think it is not a sealed motor. I don't know how much ozone can accumulate, but if it runs constantly it may be considerable.
My wife and I notice that we feel pretty crappy in the morning when we run a heater or fan all night that is not a sealed motor.

Hey, can anyone please tell me what he says at 0:43 - 0:48? He says "This system is a loan to us from---" and then I don't understand what he said.

If filter is on back, the front pulls massive air from the front.It comes from the corners of the box.THis front air is 100% UN filtered. On my meter with 1 filter on front I get over 90% reduction. With one filter on back I get less then 30% clean air.NEVER put ( only ) on back.

I would put the filter on the back side of the fan.
