Air purifying and sanitizing protection for areas up to 1000 square feet. The Air Oasis model 1000G3 Air Purifier-Sanitization system is perfect for spaces such as a kitchen, family room, conference room, pet litter box area, or areas up to 1000 square feet with moderate levels of air quality contaminants. If you have a large open floor plan area within your home or office, up to 3000 square feet, with a higher degree of air purification desired, we highly recommend one of our Air Oasis model 3000G3 purifiers. If you have a larger area (1000-3000 square feet or more) that is divided by rooms, doorways, walls, etc, we recommended placing 2 or more of the model 1000 air purifiers throughout the area for more even coverage, and faster purifying protection. The compact size of this air purifier also makes it convenient for travel, boats, campers, cottages, apartments, college dorm rooms and r.v.’s as well. You'll be amazed with the results. Within 1-3 days, and often just overnight, you will be breathing cleaner, safer, healthier air. If you’ve ever desired the fresh, clean, pure feeling of outside air after a spring rain, or a country walk through the forest, within your own home, this is the system for you.
