i tried multiple filters but somehow this one stands out for me... best taste cleanest water.. the only problem is the cost of the filters... i wish they can bring the price down... each filter roughly lasts about 10 days with 5 people together consuming roughly 3 gallons of water every day.. (so i can say each filter lasts for 30 gallons)... and then the taste changes, we don't even use the TDS meter.. and they should make filters last longer too..
