    Freshen indoor air - If you're tired of smelly basements, you should install a ventilation fan. Ventilation fans help you keep the air inside your home fresh by removing airborne contaminants such as ammonia and other odor-causing chemicals to eliminate odors.

    Prevents mold contamination - Mold and viruses can easily thrive in dark spaces. AlorAir crawl space ventilation fans keep your basement cool and dry with 780 CFM airflow. Especially if your basement has no windows, it can renew the air inside.

    Helps bathroom cleaning - It is difficult to clean a bathroom thoroughly if there are always contaminants in the air. Installing a ventilation fan helps keep the bathroom clean and dust-free because it helps suck up dust and dirt from countertops and floors.

    Cost Saving - Our high-power ventilation fans are compact and portable, and can increase air circulation in any room. This means you can install it in any space you need to dehumidify at the moment, and our panels can be trimmed to match non-standard foundation opening
