Best Deal on a 1 Micron Sediment Filter Review by dr_eck
Discount Filter's price on this filter is amazing. I bought 4 (a year's supply) just in case they figure out how low their price is. I use this filter as a prefilter for the Matrikx 1-HD20 (01-425-125-20). With my town's heavily sedimented water they extend the life of the Matrikx filter from 3 to 6 (Posted on 5/14/13)
