Including filter system and high-performance PFHxS filter.
PFHxS is one of the PFAS chemicals often called a “forever chemical” because it can persist in the environment. In Havana many homeowners hear about PFAS when water testing or reports list specific compounds, and PFHxS is one of those names you may see. You won’t be able to detect PFHxS by sight, smell, or taste, so testing is the only reliable way to know if it’s present — and a point-of-entry (whole-house) treatment gives you more control over what enters your home.
PFHxS has been linked to industrial applications and PFAS-containing products, which means it can appear in water sources in trace amounts and be tough to remove with basic filters. Common pitcher filters or simple sediment cartridges may catch particles but aren’t designed to reliably reduce dissolved PFAS compounds. That’s why many Havana homeowners choose a system that treats all household water — so you’re not relying on filtered water at a single faucet while the rest of the house remains untreated.
The most commonly recommended single option for PFHxS reduction is a whole-house activated carbon system using high-capacity granular activated carbon (GAC). Activated carbon’s porous surface can adsorb many organic contaminants, including certain PFAS, and in a whole-house installation the important factor is giving water enough contact time with the carbon so PFHxS can bind. A correctly sized GAC tank installed on the main line treats water before it reaches any Havana tap.
At Mr. Pure Water we design whole-house carbon systems around real household needs in Havana — focusing on flow rate, bed depth, and media volume instead of a small cartridge trying to do everything. That approach matters for PFHxS because the effectiveness depends on how long water stays in contact with the carbon and how quickly the media loads. We’ll size and place a GAC tank to match your plumbing and daily usage so you get consistent filtration without losing pressure; for treating PFHxS throughout the home, a dedicated whole-house GAC system is a practical, reliable choice.
