Very interested to read about your use of air movers. I have been drying buildings as a specialist for more then 20 years using both air movers and dehumidification.
Whilst air movers are becoming increasingly popular for drying carpets fast, I would also reiterate the hazards of atmospheric moisture caused by their use.
I am aware of a number of insurance claims which have been linked to the cleaning and drying of carpets in the home and one in an office complex blamed on the use of "accelerated drying equipment".
There is an inherent lack of understanding about the levels of humidity that an air mover will evoke into an area without ventilation or dehumidification.
One of the main problems is electronic equipment, i.e. TV’s, computers hi-fi's etc. Many are left on all the time or still warm from switch off. The incredibly high humidity content caused by an air mover can cause moisture to condense back into liquid on the hot components and circuit boards. Even if the equipment remains ok, this can start a short term corrosion process.
Please remember that the water doesn’t magically disappear, its just everywhere now instead of the carpet.
So therefore don’t use air movers without total ventilation or the use of dehumidifiers.
Tip: the quickest way to dry a surface with air movers is to place one at either end of an area, facing each other either side of an imaginary centre line. This will cause a circular cyclone effect, forcing the heavy wet air upwards and outwards giving maximum evaporation time before re-settling.
Advice: I have spent over £20k on air movers in recent years, and abusing them to the point of destruction (i.e. on full speed 24-7 for 3-4 months at a time) and Dri-Eze have always come out miles ahead, never managed to destroy one yet,
so that’s where my money will always go, however in this industry with such light use, I would imagine any would do for years.
Info: Dri-Eze are producing a half size, single speed, ultra quiet, (side) stackable version for under £100. I played with the prototype last month which had incredible power, as Bill demonstrated when he accidentally turned my office into a paper chase; this also comes with a "snout" to attach a 4" hose for hand held drying.
