What is the most cost-effective way to filter water?

The most cost-effective way to filter water is by using an under-sink filtration system, such as the Elite Series 2 Alkaline Filter. These systems provide long-term water purification with minimal maintenance costs, making them a budget-friendly option for households. Reverse osmosis systems, like the Elite Series 3 RO Filter, are another economical choice for achieving high-purity water. Both options ensure clean, safe, and great-tasting water without breaking the bank.
