I see thanks. I see. I always thought that after showers with the bathroom door closed, the air in the whole flat felt damp..

Thank you. My block management has confirmed that it is ok to service once a year although 6 months is preferable. They last came in January and all they did was open the ceiling hatches and look at it..... Did a bit of research: HRVs and ERV/MVHR s both supply air to the home and exhaust stale air while recovering energy from the exhaust air in the process. The primary difference between the two is that an HRV transfers heat while an ERV/MVHR transfers both heat and moisture.

Thank you. And wow that is dirty. I live in a block of flats. Was informed the ventilation system for all the flats are connected. I am hoping this means that all flats use the same incoming fresh air duct and filter which has been cleaned by the block management elsewhere in the building. And that the only filters in my flat are the extract filters.

Hi All, Does anyone happen to know if it is ok to change service the MVHR once a year rather than every six months. I am not in the flat most of the time. The MVHR button is always on. I do not cook or do anything dusty. I hoover weekly when I am around. The air flow from the ceiling vent seems the same as it has always been when it was last serviced in January and the serviceman confirmed everything was fine. I live in London. My flat is not on a main road. There are hardly any cars on my road. I am on the 3rd floor so quite high up above ground level. I do not open windows wide the whole day. Only halfway for around an hour daily if I am around. The flat was built 2-3 years ago. Just that all the dust bugs and things coming out of the ceiling holes and ladders really stress me out. So trying to minimise this event. Just wondering how often people in a similar environment to mine have their MVHR serviced. Any help much appreciated. Thank you.
