Plants are Mother Nature’s super-efficient air filtration system. The ANDREA system utilizes award-winning technology to accelerate a plant’s already potent capacity to remove airborne toxins from the air. The gadget employs active plant filtration in concert with layers of water and soil to provide a multistage system that cleanses indoor air of harmful toxins that can irritate and be harmful to your lungs.

It naturally purifies air by drawing it in and propelling it through the leaves and root system of a plant, then out through water and soil filtration and back into the room environment. 

Faq: The unit is said to consume very little energy and operate quietly (some reviews question this claim). Any plant can be used in the system and it contains no replaceable filters.

Tests have shown that Andrea exponentially improves the efficiency of formaldehyde removal from the air relative to plants alone. Tests performed by RTP Labs estimate an improvement over standard HEPA filtration systems of 4400%.

The data confirms that plants alone outperform HEPA and carbon filters at removing toxic gases from the air – though they are significantly less efficient than Andrea. Lab tests have shown that the device removes airborne pollutants 1000% faster than plants alone.

ANDREA was invented by French designer Mathieu Lehanneur with Harvard professor David Edwards.
