Donation to a Nebraska Flood Victim


SUNHEAT International is asking for your support to help your neighbors with the Nebraska Strong Flood Relief Fund. For each Mountainaire 6 stage whole home air purifier purchased at this special price for yourself, a loved one or someone in one of the stricken communities as a donation, SUNHEAT will donate $50 to the Nebraska United Way. This donation can be sent to the overall Nebraska chapter or, by typing your preferred city/town in Nebraska or Iowa, we will send your donation to the United Way serving that area. If you are donating your purchase to a flood victim, please be sure to notate that.

From our family to yours, we appreciate you helping victims of the floods by your donation and truly living out the slogan, “There is no place like Nebraska!”



The Mountainaire six stage whole home purifier system cleans the air using HEPA filtration, Ionization, Photo-catalytic Oxidation (PCO) and adjustable Ozone generation. The MA-4000 removes odors caused by pets, tobacco smoke and cooking as well as trapping and eliminating particles as small as 0.01 to 0.3 microns. Advanced PCO technology combines the natural cleaning power of a UV-C germicidal bulb with a Ti02 filter to vaporize contaminates and microorganisms such as mold, mildew, bacteria, viruses and germs. A 20KV Ionizer produces radically charged ions that collect or clump dust, pollen and other particles in the air; so they fall to the floor and can be swept or vacuumed away. The Mountainaire offers the optional power of a two plate Ozone generator to clean and sanitize not just the air but also surfaces and fabrics. The adjustable ozone can be used to destroy odors, pollutants and microorganisms in your home, office and car. This lightweight and portable purification system,with a CADR rating of 108, is small enough to fit almost anywhere. The Mountainaire is a powerful home purifier that provides a variety of settings, allowing it to be effective in almost any indoor environment and in areas from 1,000 to 3,000 square feet.
