Nybakke carries the Austin Air models. From the Healthcare model to the Healthcare Plus. Both units have a Medical Grade HEPA Filter so particle filtration will be the same. The difference is the HealthMate Plus features a more absorbent activated carbon filter bed to combat heavier chemical odors, including formaldehyde. This broad-spectrum adsorption makes it the best choice for people exposed to smoke from wildfires and offers dentists and their patient’s protection against COVID-19.
