Humidifiers remove dryness from the air and make your living space healthier and more comfortable. Just as too much humidity can cause health problems, so can too little. Asthma and allergy symptoms can worsen in overly dry air, and dry winter air can cause skin conditions like eczema. You can improve dry air conditions throughout the year with a high-quality Holmes air humidifier. We carry Holmes replacement filters and other accessories to keep your humidifier in the best possible working condition. Research says that you should replace your Holmes humidifier filter every 3 to 4 weeks for optimal performance. We carry wick filters for various models. For a pleasant new use for your humidifier, you might also consider Holmes aromatherapy tablets for humidifiers. For a minimal cost, use lavender for a restful night's sleep or refreshing citrus to energize your spirits. Most of all, keep your humidifier in top shape for long-lasting health benefits.
