We live in a tiny house with 4 people and two dogs and needed to upsize our ventilation system. We are selling our Luno e2 and it would be perfect for a tiny house with less people. It provides ventilation and heat recovery. We used it for 8 months and it works like new. I have all the components. New this system sells for $1078. We are selling it for $700. I would really like it to go and help someone else improve the air quality in their tiny house.
