The Molekule Air Pro and Air Mini+ differ in their room coverage and overall size. The much larger Air Pro has a higher air flow rate and is designed to improve indoor air quality in larger rooms up to 1000 square feet. Meanwhile, the Air Mini+ is made for smaller rooms up to 250 square feet. Both products also have differences in mobility. The Air Pro has a built-in handle and caster wheels for easy maneuvering, while the Air Mini+ is more compact and portable for travel or use in smaller spaces. Choosing the right air purifier starts with identifying your needs and preferences.
