Airfree Duo - Filterless Air Purifier that Can also Remove Odours

The innovative team behind the Airfree line of products has once again taken design and technology to a whole new level with the new Airfree Duo. This highly effective and efficient air purifier uses exclusive TSS™ technology that works around the clock to kill microorganisms in the air, such as viruses, bacteria, mould and pollen, thereby creating a healthy environment that is free of irritating allergens. Perhaps best of all, you won’t have to worry about the cost and hassle of replacing traditional HEPA filters. The Airfree TSS™ technology is filterless, which means that you can run it continuously without ever having to worry about maintenance.

The new Airfree Duo takes air purifying a step further by combining Airfree’s patented TSS™ technology with the all-new odour eliminator capsule, which can be switched on to remove cigarette smoke, cooking smells and other irritating odours from your indoor environment. While the TSS™ technology continuously purifies the air, this additional feature can be turned on and off as needed, leaving your home smelling clean and fresh.

Take advantage of this TSS™ technology and enjoy an air purifier that not only provides silent, filterless, and effective performance, but also allows you to eliminate unpleasant odours with the new optional odour eliminator capsule.

Product Features

Exclusive filterless TSS™ technology

The Airfree Duo uses exclusive TSS™ technology to heat air to 200℃, in order to destroy a wide range of microorganisms for clean air that will keep you and your family happy and healthy.

Airfree TSS™ technology provides users with a filterless air purifying product that destroys more microorganisms without requiring constant maintenance. TSS™ has been independently tested by research institutions and labs across the globe and has been found to effectively eliminate 99.99% of viruses, bacteria, pollen, organic odours, pet dander allergens, mould, dust mite allergens and ozone.

How TSS™ sterilises the air

Contaminated air enters the Airfree Duo where it is heated to 200℃ in the ceramic core, which effectively sterilises the air before it is cooled down and released back into the room. Essentially, the Airfree Duo has used technology to harness age-old science and make it accessible to consumers. Since there is no filter, you can run the Airfree Duo continuously and experience optimal performance.

Completely silent in TSS™ filterless mode

The filterless TSS™ technology works silently eliminating contaminants from your environment.

Compact and modern design

The Airfree Duo features a compact and award-nominated design that makes it easy to discreetly place it in any room. It will blend in with your existing decor while also cleaning your air.

Odour eliminator capsule

The odour eliminator capsule is what truly sets the Airfree Duo apart and makes it a dynamic model that will not only clean your air but keep it odour-free. When your home is overtaken by strong cooking smells or cigarette smoke, you can easily switch on the odour eliminator and this powerful feature will go to work eliminating odours.

Once the odour has been removed, you can simply turn off the odour eliminator. Best of all, the air purifier will continue to work on cleaning your air whether the odour eliminator has been activated or not. This added feature puts you in complete control and gives you the power to quickly eliminate odours.

Maintenance-free in TSS™ filterless mode

Unlike other air purifiers on the market that rely on HEPA filters that need to be regularly purchased and replaced, the Airfree TSS™ technology operates without the need for a filter. You can enjoy an air purifier that requires zero maintenance and kills 99.99% of microorganisms in the air. You can turn it on, forget it and enjoy a cleaner, healthier environment.

When looking to tackle unpleasant and stubborn odours, simply turn on the Airfree Duo’s odour eliminating capsule feature. Each capsule may last up to 6 months, or longer, depending on how often you activate it, so you can enjoy all the benefits of the odour eliminating capsule without worrying about frequent maintenance.


Energy efficient

Because the Airfree TSS™ technology requires no filters or fans, Airfree air purifiers are also incredibly energy-efficient units.

About Airfree

Airfree was created because there was a clear gap in the market. A Portuguese businessman was looking for an effective way to ease his son’s allergy attacks. When he failed to find the right solution, he took the initiative to create his own.

The first Airfree prototype was developed with the goal of naturally destroying airborne allergens by using heat to purify the air. After successfully testing the product at microbiological laboratories, it became clear that Airfree products should be manufactured on a larger scale so that more families from around the world could experience the benefits of a simple and effective air purifier.

Since then, Airfree has continued to innovate, create new products and reach consumers in over 60 countries across the world.
