The New Zehnder ComfoAir Q purification system is the next generation of heat and energy recovery ventilation units, a “quantum” leap over conventional HRVs/ERVs currently available on the market. The Q builds on the superior performance and established success of Zehnder’s ComfoAir systems with features such as improved heat recovery efficiencies, integrated humidity sensors and app-based controls to provide a world class, comfortable, healthy and energy-efficient indoor climate.

Filters are sold and replaced in sets of two.
Our standard filter sets are MERV 7/8 for the warm side of the unit and a smoke/pollen filter, MERV 13 for the unit's fresh air intake side AKA 'cold side.'
It is suggested to check your filters quarterly with the seasons, vacuum 1x and/or change them at least twice a year.
Each unit uses two filters at a time. Be sure to check the exterior grills for blockages at least 1x per year.
Of all our Passive House Feasibility Studies, implementing the air barrier correctly is the key to success! Having air tightness, by that we mean 3 times tighter than Code requires, attributes to over half the energy savings alone.
We are happy to provide an estimate for your project. We will focus on the air barrier system and the tapes or membranes to use in your wall and roof assemblies. We will also include a fresh air system design with a layout for your floorplan. Simply upload your planset!
