GT50 Product Specifications

The GT50 is a plug-in air purifier that uses negative ionization and ozone to kill bacteria in the air and make rooms smell fresh. Some of the bacteria it can eliminate include E. coli, MRSA, Salmonella and Giardia.

The GT50 allows you to adjust the output level of the ozone using a simple knob. It uses a mere seven watts of power to run, which is less than an energy-saving light bulb needs.

The GT50 can neutralize odors from pets and smoke, allowing you to breathe clean air. However, it does give off an ozone smell, which some people can’t stand. Others consider the clean ozone smell to be desirable when purifying air.

Where Can You Use the GT50?

The GT50 can purify the air in an area of up to 50 square feet. This includes bathrooms, laundry rooms and closets. It may be able to provide coverage for work areas like cubicles and small offices, and it is also recommended for kitchens.

It can, however, be used in rooms that are larger than 50 square feet such as bedrooms, but it may not be the best air purifier for these spaces. The modern design and small size of the GT50 allow it to seamlessly become a part of the decor wherever you plug it. It runs quietly and is unlikely to become a distraction.

Can You Travel with the GT50?

The GT50 weighs only five ounces and can fit in your hand, making it very easy to transport. Its compact size makes it great for travel if you’re worried about what will be in the air where you are staying.

Because it is best for purifying the air in a small space, the GT50 would be great in a cabin or pod hotel. A conventional hotel room is larger than 50 square feet, but you can still eliminate strange smells by plugging in the GT50.


Reading air purifier reviews of the GT50 can help you to gather information about the product and decide whether to purchase it. Some users find that the ozone smell is intolerable and causes headaches, but others don’t mind it at all.

If you are trying to purify the air in a larger space, you may get better results with a purifier that can handle more than 50 square feet. However, the small size of the GT50 may make it the best air purifier for those who wish to enjoy fresh clean air while they are away from home.
