For some reason this past month I have smelled a off smell like in my laundry room/ back porch. The shark clean sense air purifier max has been amazing! I can see in real time when the air quality changes! And what percentage is good or bad!! Then it fixes it and leaves my home smelling amazing! Honestly rather or not your just has a funny smell or not everyone should have one of these! My house smells amazing and I have not had a allergy flare since I started using it!
