Profile: HMI Industries, Inc. specializes in the manufacturing of the indoor air quality system. Our Filterqueen system consists of the majestic surface cleaner and the defender room air cleaner. These high-quality products are used to remove both surface and airborne allergens, dirt, and dust from home interiors. Our majestic is the effective surface cleaner for homes. Its patented cone-shaped filters are the key to maintaining continuous, powerful cleaning. Our defender room air cleaner works 24 hours a day to remove indoor air pollution at homes, at a filtration level that is higher than required in many hospitals. Our defender actually reduces more of the tiny, harmful particles HEPA cleaners leave behind.
