Yes, we currently only sell Austin Air. We own a medical practice, and we are 100% satisfied with the air filtration by Austin Air, so recommend and sell only this.
Reasons we love Austin include: 360 degrees air suction, Low/No EMF(the ones with blue light are high EMF), excellent scientific research (backed by great institutions like Johns Hopkins), great filter life, etc.
PS: More professional air purifiers may be added to our website as we test and are satisfied with their performance.
