I have personally experimented with a combination of carbon filter, sediment filter and RO filter(which are the main components of RO filter unit) and I have also used Livpure, to be honest, quality wise Live pure sediment and RO candles are far superior than the other and normal category components available in the market and that is why the price is also little on the upside but that's worth it, because the longevity is the key and when it comes purification, I still believe that Livepure has that edge and with this newly added technology it becomes a really essential product in our household.
Excellent hunt.
Thank you and Have a great day.
