This whole house water filter system by Express Water offers a 3-stage filtration process designed to remove iron, manganese, lead, and arsenic, which are common causes of staining and unpleasant taste in water. It’s particularly useful for households experiencing reddish-brown stains on fixtures and laundry or those wanting to protect plumbing and appliances from sediment buildup. The filters are NSF certified, ensuring reliable contaminant removal, and they last between 6 to 12 months depending on water usage, which is decent for whole home systems.

With a maximum flow rate of 17 gallons per minute, it should handle typical household needs without noticeable pressure drops. Installation is straightforward with a freestanding design, a sturdy stainless steel bracket, and helpful pressure gauges and release buttons that simplify filter changes. However, the system does not reduce total dissolved solids (TDS), so if you need that, a reverse osmosis system would be necessary. Weighing 57 pounds and measuring about 23.5 by 8.5 by 29 inches, it requires a fair amount of space, which might be a factor for smaller utility areas.

The manual operation and regular maintenance every 6-12 months are manageable, though some users might prefer a system with longer-lasting filters. This filter provides a solid option for those looking to improve water quality by targeting iron and manganese, protect home plumbing, and enjoy clearer, better-tasting water throughout the house.
