Salt Walls Don't Purify Air Like You Think They Do
Salt walls add warmth and visual appeal, but their air-purifying and negative-ion claims remain unproven. They cannot replace ventilation, humidity control, HEPA filtration, or safety alarms. Install them securely in dry rooms, manage moisture, clean only when dry, and monitor for damage. Treat salt walls as decorative features, not medical treatments or purifiers.
