It depends on what you're trying to filter out? If it's total dissolved solids (TDS), then you might be surprised to find out that many water filters apparently do little in this regard? We did some simple testing of the most popular filter used in our office, Brita pitcher water filters, and discovered they typically only achieved a 5% reduction in TDS using our tap water. Comparing Deer Park bottled spring water which represented an 85% TDS reduction from our tap. Though the only readily available filter that reduced TDS to 0-1% was Zero Water pitcher filters. It was by far the most effective water filter, outside of using a reverse osmosis system.
Besides using a TDS meter, we tested with a Precipitator, and Zero Water filters produced clear liquid. Others resulted in various degrees of brown, akin to coffee color in nature. Needless to say, we all switched to Zero filters.
