Whole House Twin Big Blue BB2-20

The AMPAC USA Whole House Twin Big Blue BB2-20 delivers comprehensive filtration for every water source in your home. Built for households that want cleaner water at every faucet, the BB2-20 combines two effective filtration stages in a single high-capacity system, making it a practical upgrade for homes with well water or municipal supplies alike.

• 4" x 20" sediment filter (20-micron) removes sand, silt, rust, and scale
• 4" x 20" carbon block filter (10-micron) reduces chlorine, chloramines, VOCs, pesticides, and herbicides
• Flow capacity of 15–23 GPM to keep pressure steady during peak household use
• Two-stage design protects plumbing and appliances from sediment buildup
• Straightforward installation and servicing suited to the average homeowner

The first stage uses a 4" x 20" sediment filter rated at 20 microns to capture larger particles such as sand, silt, rust, and scale before they can affect your plumbing or appliances. Water then passes through a 4" x 20" carbon block filter rated at 10 microns, which adsorbs chlorine, chloramines, VOCs, pesticides, herbicides, and other compounds responsible for off-tastes and odors. Together, the two stages provide thorough purification for drinking, cooking, bathing, and everyday household use.

Like the rest of the AMPAC USA lineup, the BB2-20 is built for durability while remaining easy to install and service without professional help. Its construction reflects the same engineering standards AMPAC USA applies to its commercial water filtration systems, scaled for residential use.

The BB2-20 suits a wide range of homes, from single-family houses to larger properties. It's especially useful for well water, where sediment and iron are common, and for municipal water where removing chlorine improves taste and safety. With a flow capacity of 15 to 23 GPM, it maintains water pressure even when multiple fixtures are running at once, delivering filtered water to every tap in the house.
