We are a family of 3 people and we bought puriet. We had been convinced by the seller that it will last around 3 months atleast and guess what after 20 days the filter was useless and had to be replaced.
When we raised our concern to HLL the guy from their company said tht it was useless product as far as family is concerned and we had to throw that piece of sh*t and get a new purifier.......CONCLUSION buy it only if are alone and do not buy it if more than 2 people goin to use it.
