So now we have an electric connection (7 days and counting) I've started to run the MVHR unit 24x7 but since then we've started to notice little flies in one room. Having pulled off the MVHR supply air vent in this room it contains many of the little beggars trapped in the foam as per photo. Two weeks back I vacuum cleaned the MVHR filters, apart from being a bit dirty with 12 months of limited use there were no flies, today the exterior filter contains a few of the same flies (which I might expect as it does its work) and the house side filter seems ok. FYI our new build is called Field Cottage, it is in the middle of a field - currently just ploughed after a crop of wheat harvested 6 weeks ago, while there are flies about I would not say there are swarms of these types. Have to admit since the air tightness test was done, also the same day the electric was connected, me and my partner don't feel the MVHR is delivering the same volume of fresh air - maybe the summer by pass has turned off or worse case a pipe has popped somewhere - yet to investigate. Unit is a Vent-axis Sentinel Kinetic plus B. Can the flies get past the filters or do I have my partners worse night mare, a fly infestation in the MVHR pipework? (She told me this many times over the long build and we pretty much kept all the pipe work sealed and ditto the MVHR).
