Hunter Care-Free PLUS humidifiers feature a patented "PermaWick" design which provides effective humidity control while eliminating the need for frequent wick filter replacements. What's the secret? In addition to specifically inhibiting the growth of bacteria and fungi on the plastic parts of the humidifier, the exclusive metal PermaWick filter is cleanable and reusable, saving up to $45 per season in wick filter replacement costs.
