We have recently moved into a first floor apartment in a new building that is approximately 9 months old. We are finding that we are absolutely plagued by a constant layer of dust building up in each room, regardless of the extent that the room is used.
The home is fitted with a Nuaire MRXBOX (MVHR ECO - ECO2) which is connected by ducting to a ceiling vent in every room (two in the larger rooms) with the exception of the entry hallway.
I dusted, hoovered, and mopped each room 2 days ago and there is already a thick, visible layer of dust everywhere except the hallway (which doesn't have a ceiling duct). The dust appears to be distributed fairly evenly throughout the surfaces and skirting boards of each affected room.
We open all the windows most days as it is typically warm here. We close all windows at night.
I have some questions about the MRXBOX:
- Is this unit likely to be responsible for the continual flow of dust into each room with a vent?
- If so, is there anything I can do to reduce the amount of dust coming from the vent?
- Are there any negative effects of disabling the unit (i.e. powering it off)?
