Decentralised Mechanical Ventilation with Heat Recovery
a MVHR for 1 room. Unlike the MVHR that has 1 motor and heat exchane unit for the whole house, a dMVHR has these built in every unit. (decentralized)
It can be easier to install afterwards in a single room, e.g. bathroom since it’s ductless

reviews UK
- dmev is loud
- video doesn’t recommend dMVHR because they need to be in pairs, are expensive.
similarly decentralized & ductless, like a mini split
