20" Big Blue 3 Stage | Whole House Water Filter System For Iron, Manganese, Sediment, Chlorine & Chemical Reduction | Sediment + Iron + Carbon

Applied Membranes Iron Manganese, Sediment & Carbon Whole House Water Filtration Systems are the ideal chose for homes using a chlorinated water supply, such as city water when Iron and/or Manganese are a concern. Stage 1 sediment filter removes dirt, rust, sand, dust, and other particles from the water down to 5 microns - protecting your plumbing & appliances and priming the water for the later stage filters. Next the water passes through Applied Membranes specially formulated Iron & Manganese filter which offers iron reduction from 3 to >0.01ppm and Manganese Reduction from 1 to >0.01ppm. This is followed by Applied Membrane's advanced High Performance carbon filter which removes chlorine, chloramine as well as 100s of other chemical contaminants commonly found in tap water.

System Specifications

Designed, Assembled, and Quality Controlled in the USA using quality parts from USA and world-wide.

5 Micron Sediment Filter

Removes Dirt, Rust, Sand, Dust, Silt, and other particles from water down to 5 microns. This protects your plumbing & appliances and extends the life of the carbon filters. The graded pore structure uses the entire depth of the filter - capturing larger particles in the outer layers and decreasing in size as it reaches the center. This maximizes the dirt holding capacity, giving more time between changeouts.

Iron & Manganese Filter

Applied Membranes Iron & Manganese Filter offers Iron Reduction from 3 to >0.01ppm and Manganese Reduction
from 1 to >0.01ppm. Safe for drinking water applications.

Filters up to 50,000 gallons of water with 3ppm Iron.

HP Carbon Block Filter with Advanced Chemical Adsorption

Rated at >240,000 gallons for chlorine reduction, Applied Membranes high performance carbon filter absorbs chlorine and unpleasant tastes and odors from
the water and corrects cloudiness (turbidity). Our advanced HP formulation also removes residual chlorine, chloramine, VOCs, pesticides, herbicides, and 100s of other harmful chemical contaminants commonly found in tap water. Made with 100% coconut shell carbon.

Fast and Simple DIY Installation
& Worry-Free Maintenance
