Aquafresh RO water purifiers are unbranded product liked up by middle class families.it is cheap but customet do not have faith on this product.i am using this water purifier but has complaints with this product.after using for 2 months the adapter stopped working and I had to replace adapter.Also dealers or agents dealing in this unbranded product said that there is free lifetime servive but charges money for every service.thus this product need to be improved more and advertised to attract more customers
