Steam inhalers are devices that produce warm, moist air to help relieve respiratory issues. They are commonly used to ease symptoms of conditions like asthma, bronchitis, and sinusitis. By inhaling steam, users can help open up their airways, reduce congestion, and soothe irritated nasal passages. These inhalers typically consist of a water reservoir that heats the water to create steam. Some models may include added features like adjustable temperature settings or essential oil compartments for enhanced benefits. Steam inhalers are generally considered safe and can be used at home for quick relief from respiratory discomfort.
