Airfree Air Purifiers

Airfree has a unique purification process in that it pulls in air by convection and destroys harmful pollutants through its patented system that does not use filters.  Airfree sites numerous lab tests that conclude there were reductions in mold and bacteria from using the product.  Airfree units do not filter air but destroy micro-organisms and are therefore not rated under the clean air delivery rate program.

Airfree Company info

Airfree is a fairly small air purifier company based in Europe. Detailed information on the company is hard to come by, but they are relative newcomers to the air purification industry. Airfree’s purifiers use a unique process to clean the air. Its purifiers are also fairly stylish looking and conveniently small, as well as quiet; the company claims to have won awards for design, though they do not specify what those awards were.

Airfree Purification Technology

Airfree air purifiers work in a very different way from most commonly used home cleaners. They do not use filters, ionizers, or any of the typical air-cleaning methods. Instead, according to Airfree, its purifiers work by using a unique process called the Thermodynamic Sterilizing System, or TSS. “Heated capillaries” in the units are used to incinerate microorganisms that pollute the air.

The company explains the process: “Contaminated air is dragged into Airfree’s ceramic core by air convection and microorganisms are destroyed at high temperatures regardless of how resistant and dangerous they might be.” The temperature in these units reaches up to around 400 degrees Fahrenheit. The organic particles that pass through the capillaries at such high levels of heat are denatured, or fundamentally changed, and as a result are, according to Airfree, rendered harmless. The harmless particles are released back into the air. Airfree claims that its products destroy 99.9% of all organic particles that pass through them. This process is in some ways analogous to the ultraviolet lights used in some other air purifiers to kill harmful organism, but Airfree’s system means that there is no need to periodically change a light.

Airfree Technology Targets Organic Pollution

It is very important for potential customers to understand, therefore, that all of Airfree’s air cleaners have a limited application: they only target organic pollution, such as mold, fungus, viruses, and bacteria. Whether this is acceptable or not will depend upon each buyer’s own unique situation. Airfree’s website at http://www.airfree.com includes, among other things, a long list of tests conducted by various agencies backing up the company’s claims that their products reduce organic pollution.

Airfree Models

Airfree currently offers three different models of air cleaners, detailed below, which differ mainly in strength and appearance. Prices range from the low to mid-$200s. An added advantage is that there are no lights or filters to replace, ever, meaning that users will not need to worry about the cost of replacements in addition to the initial price. Thus the true cost of an Airfree is far less than that of a standard air purifier of the same price (but remember the tradeoff: it also does not reduce some pollutants that those other purifiers do). Airfree also claims that all its offerings use about the same, or less electricity, than a 50-watt light bulb.

Note that, despite the high levels of heat used by Airfree products, reviews have stated that they do not cause the room to heat up, and the design of the purifiers prevent them from becoming a hazard.
