This customer has a house that's located close to the highway and he was because of this concerned about PM 2.5 creeping in to his house. He also wanted to have more oxygen in his bedroom since they were 4 people (two adults and two kids) sleeping there at the time.

To solve these issues we therefore installed our 'Whole House ERV' system with an electrostatic filter. The former makes sure that there always is enough oxygen in every room of his house, and the latter makes sure that there is little too non PM 2.5 entering his house.
