Decentralized ductless ventilation system: Zehnder, TwinFresh, or Lunos?
Background…We are building a 2000 sq ft home at 7000 ft in Colorado, climate zone 6b, with about 7000 HDD. The house will be tight but we are NOT going for any certification. It is one story, 3 bed, 2.5 bath. My spouse has lots of allergies and is opposed to duct work. As we live with doors and windows open a fair amount of the year he is opposed to adding ductwork in the house for an HRV OR ERV. Whether that makes sense is NOT the question.
Question.. apparently several companies make decentralized ductless ventilation systems. Martin wrote two years ago about Zehnder, and also mentioned Lunos and TwinFresh. Any opinions or experience about these or others would be appreciated.
Likely there is relevant info you need to answer this question, just not sure how much to bore you with.
Thanks in advance from a building newbie, be kind please,
