Godrej Aer Pocket is best to remove unwanted smell. It cost only 55 rs and lasts for 20-30 days. It is more effective then any other room freshener. It has slim gel which lasts the fragrance longer. It is easy to use, just tear and hang. It keeps our bathroom/ room fresh with fragnance of flowers. Even people who come to our house has noticed the change and complimented us.
