Recommended MVHR unit features?

...and the manufacturer adds a nice mark-up. Firm handshakes all round and guess who pays...

I’m guessing that PH org charge manufacturers a pretty penny for testing a unit . . . 

They don't charge anything, though the manufacturer's have to use an accredited laboratory.

 

But it's your money and your choice :)

I spoke to the manafacturers engineer (proair) about the difference between their certified unit ( certification has lapsed I think now) and their non certified unit. 

 

He said they were identical apart from some extra sensors and gadgets on the passivhaus one, I can't remember what. He suggested I was just paying more for something of no greater utility and more chance of failure.

 

Having limited experience of various brands I am happy with it. I would suggest if you can to physically get your hands on a unit and poke at it before you buy. Remove the filters, play with the controls etc. Build quality is very tactile. I was disappointed with vent axia and domus but impressed with blauberg.
