Don’t panic—you don’t need to filter your whole house. Most silica problems are solved by treating just the water you drink or use for coffee and ice. A small countertop RO unit costs about as much as a good pair of sneakers and lasts for years.
For the whole house? That’s a bigger investment, like buying a new refrigerator. But if your dishes look like they’re wearing a thin film of glue, or your shower doors are permanently fogged, the satisfaction of crystal-clear water is worth every penny.
