Keeping your indoor air clean is an important part of maintaining a healthy home. With the AeraMax DX5 Air Purifier, you can easily improve the air quality of small rooms 100-200 square feet in size. The 4-stage hospital-type filtration effectively removes 99.97% of airborne particles as small as .03 microns including pollen, ragweed, allergens, viruses, germs, dust mites, mold spores, pet dander, and cigarette smoke. AeraMax is a HEPA air purifier with an activated carbon filter that helps removes odors as well. When cold and flu season comes around, activate the Aera+ Mode to fight seasonal airborne germs. The Dx5 is the best air purifier for ultra-quiet performance and it even lets you know when it’s time to change the filter. The best part is that never have to make adjustments. The AeraSmart Sensor monitors the air quality and automatically adjusts the fan speed to keep the air purifier all the time. Perfect for a child’s room.
