Backed by Science

Koru's nano PCO filter technology purifies air by generating reactive hydroxyl radicals and superoxide ions that destroy micro-organisms, bacteria, viruses, mold, volatile organic compounds, and odors.

This process is performed without emitting ozone or any other harmful byproducts, ensuring the air you breathe is clean and safe.

Sustainable air purification

in 3 simple steps

  • koru-plant purify the air

    Plants purify the air and create oxygen

    Through a natural process occurring on the plant's roots called bioremediation, Koru captures and destroys chemical compounds while generating fresh oxygen.

  • koru one- nano coated ceramic filter

    Nano-coated ceramic filter destroys VOCs

    The air purification is boosted with a nano-coated photocatalyst filter that eliminates VOCs, molds, odors, and PM2.5. No replacement is needed, ever.

  • koru one uv light

    UV light eliminates viruses and bacteria

    With ozone-free UV light, Koru safely eliminates up to 99% of airborne bacteria and viruses.

Deep Air Sanitation

Powerful UV-C LEDs zap and destroy up to 99% of airborne bacteria and viruses, ensuring the highest quality of air sanitation.

  • koru one- eliminate particles

    Eliminate pollutants

    An innovative air purifier combining the natural air filtration properties of plants’ roots with a high-end, sustainable, nano-coated PCO filter technology.

  • koru one- wash and use it again

    Wash It and Use Again

    The filter is made of expanded ceramic foam, coated with a special titanium powder. This ensures that all our filters will last indefinitely while maintaining the highest effectiveness.

  • koru one- truly ozone free

    Truly Ozone Free

    Powerful UV LEDs "zap" and destroy airborne organic pollutants, viruses, and bacteria. By fine-tuning the wavelength, we ensure KORU never emits any potentially harmful ozone.
