Humidifiers are amazing things. Whether it's reducing the static shocks you get during the dry winter months or easing the sting of a sore throat or sinuses any time of year, they just putter along, keeping our air moist. Did you know that your humidifier needs a filter, however? Especially evaporative humidifiers like your Essick? This two-stage filter traps allergens before they can go back into your breathing air and it also helps reduce pet and household odors. Change your filter every four to six months for best results.
