Inexpensive ultraviolet lights for use in air-conditioning systems are available for purchase from Alpine Home Air Products, the AC Outlet and Amazon.com, as of 2015. These three retailers provide inexpensive options to help sanitize air conditioners during operation and help cut down on the spread of many undesirable contaminants.
Alpine Home Air Products offers UV purifiers that work alongside air conditioners to help create sanitary conditions in the home or office. Many products available from the company ship for free to any destination in the United States, and Alpine's premium guarantee applies to each sale. This allows customers to return products within 30 days if not completely satisfied, and Alpine honors all manufacturer's warranties. The premium guarantee also includes unlimited technical support for products purchased through the company. The AC Outlet also offers free shipping on many items, and the company has a low-price guarantee that allows them to match other advertised prices in many cases to help ensure customers get inexpensive UV lighting.
