Alliance 7 Global, Sushruta White (Ionizer Air Purifier), Coverage upto 300 SQ FT, Maintenance Free

One of the cheapest and most effective air purifier.One can use the product for 24*7 and no additional cost of maintenance and filter change.

Smallest in size and cheapest of air purifier with no harm to human body.Might buy one more product soon.I hesitated to buy in the beginning as new company name but it's worth the range.
