The Respira air purifier uses nature to improve air quality in your home. Biofiltration is the term and essential to this process: real, live plants. So, a purifier but also a garden. With air actively pulled through the top of the unit, dust and particulate matter are filtered before passing through the plants\u2019 active root zone. Beneficial organisms in the root zone capture and permanently destroy airborne toxins that we would otherwise be breathing as naturally purified air is then released through the front of the unit. A funded Kickstarter.
