I had bought this air purifier to my home. It is cost was 10500 INR when comparing thus cost to worth it was very poor.It does not purifies the air properly. Sometimes this device causes annoying sound and makes heat.One day in a stromy weather there was high and low voltage disturbance happens in the electricity, this is damaged the circuit of this device to the customer care as less experienced as the serve the decice for one and half months till it causes problems.most of the time it was not works regularly. Design is bulky and if the designs sleek and slims it would looks more attractive. I am not satisfied with its service. So I suggest everyone to select room purifier device rather than this.
