The Airfree® Lotus air purifier combines a distinctive design with exclusive technology, allowing a change of colors and the opening of the device’s petals, all while gradually reducing germs, viruses, bacteria, dust mites, mold spores, dander, pollen, ozone and numerous other airborne contaminants in rooms up to 650 sq. ft.
The Airfree® Lotus is a silent, maintenance-free air purifier inspired by the lotus flower. Designed for rooms up to 650 sq. ft., it uses Airfree’s patented Thermodynamic Sterilizing System (TSS™) to gradually reduce mold spores, bacteria, viruses, dust mite allergens, pollen, pet dander and other airborne microorganisms. With no fan, no filters and no replacement parts, it’s a top choice for bedrooms, nurseries and any room where noise and space are a concern.
How Airfree TSS™ Technology Works
Instead of trapping particles in a filter, the Lotus uses heat, the same idea as boiling water. Room air rises into the unit by natural convection and passes through a patented ceramic core that reaches nearly 400°F, where microorganisms are destroyed. The air is cooled before it returns to the room, and the unit adds no noticeable heat to your space. According to Airfree, up to 99.9% of the microorganisms that pass through the core are destroyed, no matter how small they are.
Why Choose the Airfree Lotus
Completely silent: No fan and no motor, so it’s ideal for bedrooms, nurseries and offices.
No filters or maintenance: There are no replacement filters to buy or change. Just plug it in and let it do the job.
Great for mold, allergy and asthma concerns: By destroying airborne mold spores, Airfree helps keep spores from spreading and starting new colonies, and it breaks down the allergens released by dust mites.
No ozone, ions or UV light: TSS™ technology produces no ozone, ions or UV light. In fact, independent tests in Sweden showed Airfree reduced ozone by 26%.
Low energy use: Just 58 W, with no fan or filters to run or replace.
Small and portable: At 13 inches tall and 5.2 pounds, it fits on a nightstand, dresser or shelf.
An Award-Winning Lotus Design
The Airfree® Lotus changes colors and opens its petals, inspired by the striking beauty of the lotus flower. Let it cycle through colors or choose the one you like best, and change it whenever you want. A touch button adjusts the night light’s brightness or turns it off. The light doesn’t affect the sterilizing function, so it makes a soft night light for children’s rooms and nurseries. Many people find that colored light, an idea known as chromotherapy, helps create a calm and welcoming room.
The Lotus was launched in 2013 at the International Housewares Association (IHA) show in Chicago, where it was named one of five finalists for the IHA Innovation Award among about 600 new products.
Independently Tested
Airfree’s patented TSS™ technology has been tested in real-life conditions by world-renowned institutions and ISO 17025 laboratories in several countries, including the USA, Sweden and Germany. You’ll find Airfree’s test reports in the More Info tab.
Getting the Best Results
Airfree works gradually, so keep the Lotus plugged in and running in the same room 24 hours a day. Turning it off or moving it to another room lets contamination build back up. Use one Lotus for each room up to 650 sq. ft.; larger rooms need more than one unit. Results depend on the room, its airflow and how much contamination is present.
Available in more than 60 countries, Airfree purifiers are made in Europe and reduce airborne microorganisms naturally, without chemicals or filters. The Airfree® Lotus is CARB certified and backed by a 2-year limited warranty.

Does the Lotus heat up the room? Not noticeably. Airfree compares two units running in the same room to the body heat of one 155 lb person.
Does it change the humidity? No. Airfree does not change the room’s humidity level.
Why doesn’t Airfree list a CADR rating? CADR (Clean Air Delivery Rate) measures how much filtered air a unit delivers for smoke, pollen and dust. Airfree doesn’t filter; it destroys microorganisms, so its results are measured by incubating air samples in a microbiology lab.
Can I move it from room to room? Airfree recommends keeping it plugged in in the same room around the clock. Because the technology works gradually, contamination in the first room starts to rise once the unit is moved.
Should I turn it off when I leave the house? No. For the best performance, leave it on. If it’s unplugged or the power goes out, it takes about the same amount of time to bring contamination back down to its earlier level.
Can I use it in a closet or small room? Yes, as long as the space is at least 43 sq. ft. (353 cu. ft.). In a smaller space, it may warm the room.
Will one unit in a hallway clean the rooms next to it? No. It will reduce airborne contaminants in the hallway itself. Place a unit in each room you want to treat.
Can I use it in rooms with air conditioning or heating? Yes. Airfree works in rooms with air conditioning and heating systems.
How do I know it’s working? Feel the top lid. If it’s cold, try another outlet and make sure the unit stands upright for at least 1 minute. Blinking top lights mean the unit isn’t upright.
Where do the microorganisms go? Microorganisms are made mostly of carbon, oxygen and nitrogen. At nearly 400°F, they break down into carbon dioxide and water. A microscopic trace of ash may remain inside the unit or on the top lid.
Does the night light affect how well it works? No. The night light is decorative and has no effect on the sterilizing core.
About Airfree
Airfree began with a Portuguese businessman looking for a natural way to ease his son’s allergy attacks. His first prototype used heat to destroy airborne allergens, and after successful testing in microbiology labs, it grew into a full line of home and commercial air purifiers. Today, Airfree products are made in Europe and sold in more than 60 countries across Europe, the Americas, Asia and Africa.
Comparisons
Compare Airfree Models
Every Airfree air purifier uses the same patented TSS™ ceramic core, which destroys airborne mold spores, bacteria, viruses and allergens with heat instead of trapping them in a filter. The models differ mainly in room coverage, size and night light, and the two hybrid models add a fan and capsules for odors and particles. Click a model name to see its full details.

Specifications are from Airfree and may change without notice.
Silent or Hybrid?
Most Airfree models have no fan at all, so they work in complete silence around the clock. The P3000 Plus and Elite are Airfree’s hybrid models. Each adds a fan and can use capsules when you want extra help with odors, smoke, chemicals or particles, then goes back to silent TSS™ operation when the fan is off. Both hybrids can be run from a remote control or smartphone app, and the Elite also works with voice assistants.

Airfree Lotus Air Purifier: Silent Filterless Air Sterilizer5.0
Review By Trish
Peace of Mind
I recently purchased the Lotus to place in our living room in hopes of creating a healthier environment for my family. My youngest son in particular has autoimmune disorder and naturally I want to provide him with the best life possible. Barb was so incredibly helpful, kind and generous. She went above and beyond to help me in my time of need. My son has now asked for a Lotus in his room. If it gives him peace of mind as well, it is well worth the costs.
