Including filter system and high-performance Magnesium filter.
Magnesium is a natural mineral that can dissolve into household water from surrounding rock and soil. At low levels it’s common and generally harmless, but when concentrations rise it changes how water behaves around the house. Havana homeowners often first notice effects indirectly—water that feels hard, cloudy spotting on fixtures, or soap that won’t lather well. Because magnesium frequently occurs with calcium, testing is the only sure way to identify which mineral is responsible.
Higher magnesium levels don’t always alter taste or smell, so the practical signs tend to appear during everyday use rather than in a glass. Mineral-laden water can accelerate scale buildup inside water heaters, pipes, and appliances, and leave stubborn residue on dishes, shower doors, and faucets. A simple water analysis is the best way for Havana families to determine whether magnesium is a notable part of their home’s hardness profile.
To reduce magnesium at the point where water enters your house, the most effective single-filter solution is a whole-house water softener that uses ion exchange. These systems remove hardness minerals like magnesium by exchanging them for sodium or potassium ions as water flows through the resin, delivering balanced water that rinses cleaner and helps prevent scale before it reaches Havana showers, sinks, and appliances. Treating all incoming water ensures consistent protection throughout the home.
A correctly sized ion exchange softener is chosen based on your water’s hardness, household size, and usage, then installed so every tap in Havana benefits. The resin is periodically regenerated to maintain steady magnesium removal, unlike many media-only filters whose effectiveness can decline. If lowering magnesium—not just improving taste or odor—is your priority, this targeted whole-house approach is usually the best choice; Mr. Pure Water can test your water and design a system tailored to your needs.
