AirCycler and VOCs

[bobo]

I am planning to have an AirCycler installed to bring in fresh air. Seems like there are some issues with ERVs, mainly cost and payback, and this may be a cheaper solution to accomplish the same thing. What happens if the AirCycler only has supply but no exhaust? The house envelope is very tight, so I wonder how this is supposed to work. My concern is that maybe fresh air is coming in but there is no way for VOCs to leave. Also, what about environmental ozone? If I run it only at night when ozone levels are lower, can I avoid bringing in polluted air?

Aircycler is a "positive pressure" ventilation system, relying on building leakage to balance the pressure in the house. There are many exhaust ventilation devices in the average house - clothes dryers, range hoods, fireplaces, central vaccuums, natural draft appliances like water heaters, and bathroom fans. To insure that there is some exhaust ventilation, a cycling control can be added to a bathroom fan so that humid or bad air will be exhausted on a regular basis from the bathroom. Slight positive pressure is okay in a warm climate.

Monitor the %RH when ventilating. Keep the %RH below 50%. Fresh air ventilation is good but a poor "trade off" for high indoor humidity that grows mold and dust mites. If you live in a green grass climat, to have both consider supplemental dehumidification. Another option is a ventilating dehumidifier made to ventilate, filter, and control indoor humidity.
