Warm moist air may alleviate sinus congestion. Experts recommend a vaporizer or steam from a pan of boiled water (removed from the heat). Humidifiers should be used only when a clean filter is in place to preclude spraying bacteria or fungal spores into the air. Warm compresses are useful in relieving pain in the nose and sinuses. Saline nose drops are also helpful in moisturizing nasal passages.
