Including filter system and high-performance Bisphenol A (BPA) filter.
Bisphenol A (BPA) is a manufactured chemical used in some plastics and resins that can sometimes make its way into water in very small amounts. While people commonly hear about BPA in food packaging, it can also appear when plastic materials contact water during production, storage, or distribution. Because BPA is typically a trace contaminant, you likely won’t detect any change in taste, smell, or appearance of your water, which is why many Postil homeowners choose to limit BPA exposure when possible, including at the tap.
BPA is often categorized as an emerging contaminant — present at low concentrations and not always removed by simple sediment filters. It can enter water through contact with certain plastics, liners, or coatings, or via broader environmental pathways that reach source waters. Choosing BPA-free products in the kitchen helps, but it doesn’t control what comes through every faucet in your Postil home. A whole-house filtration strategy provides consistent treatment for drinking, cooking, bathing, and laundry so the entire household benefits.
The single most effective whole-house filter type for reducing Bisphenol A (BPA) is a high-quality activated carbon unit. Carbon media remove many organic compounds by adsorption, capturing trace contaminants as water flows through. Installed at the point of entry, a whole-house activated carbon filter treats all water entering a Postil residence so BPA reduction applies throughout the home rather than only at one sink.
Not all carbon filters deliver the same performance — factors like carbon variety, contact time, and proper sizing for your home’s flow rate make a big difference. A correctly sized whole-house activated carbon system increases water-to-carbon contact, improving reduction of contaminants such as BPA and eliminating the need to depend on pitchers or single-faucet devices that cover only part of the house. Mr. Pure Water can assess Postil plumbing and household water use to recommend the right whole-house carbon solution so your filtration works reliably every day.
