I had purchased this sharp air purifier from a digital store and I am sharing my experience about this product this product. The product is delivered and installed on the same day of my purchase which is good. The product works excellent for 1 month but after that it started giving problem. I contacted manufacturer service centre and centre and raise a complain about the product. The technician told me that we have to change one part of the product which costs me around 300rs.I will not recommended this product to anyone because of pathetic service provided by the manufacturer
