British ventilation specialist with a deep parts network and the country's most-installed mid-range MVHR. The unit independent installers reach for first when the project is a standard 3-bed retrofit rather than a Passivhaus build.

The brand Passivhaus designers default to. Class-leading efficiency, very low fan power, and a commissioning workflow that respects how the building actually performs. The right answer when the fabric of the home is already doing its part.

The original Positive Input Ventilation manufacturer in the UK. The Drimaster range is the unit most damp-and-mould specialists install when MVHR is not on the table, and the warranty record is reassuringly dull.

British ventilation manufacturer with a long history in trickle vents and MVHR. The HRV Q Plus range is the unit specifiers reach for when the budget is tight and the project still needs proper heat-recovery ventilation.

Dutch MVHR specialist whose Renovent range is the quiet, considered alternative to Zehnder at the high end. Strong measured efficiency, low fan power, and a tidy app that respects how the building actually performs.

British ventilation manufacturer best known for the ATMOS PIV range and a strong portfolio of low-energy extract fans. Often the brand independent damp surveyors recommend when Nuaire is already on the quote.
