A Japanese household company claims that its linen and fabric spray Natucair “kills >99.9% of the SARS-CoV-2 virus that causes COVID-19.”
“We are extremely proud of our team of scientists and researchers who have made this groundbreaking confirmation,” says Yuya Suzuki from Earth Corp.’s research and development team. Earth Corp. is Natucair’s parent company.
“Every day, Filipinos should be able to have options and products that can help them stay safe from the dangers of COVID-19, and we’re happy to add Natucair to that list.”
According to Earth Corp.’s press release, studies made by the Japan Textile Products Quality and Technology Center in Kobe showed that Natucair effectively killed>99.9% SARS-CoV-2 in suspension.
The test mixed nine parts of Natucair with one part sample of the SARS-CoV-2 using plaque assay protocol. After five minutes of contact, the samples were re-examined to see the effect on the SARS-CoV-2 particles.
Fabrics have been seen as a potential point of virus transmission. In February 2021, the BBC reported a study led by microbiologist Dr. Katie Laird that looked into the survival rate of COVID-19 on commonly worn fabrics.
“These fabrics “pose a risk for transmission of the (COVID) virus,” said microbiologist Dr. Katie Laird in an interview on BBC.
Laird’s study showed that, without intervention, the virus can stay alive in different kinds of fabrics for as long as 72 hours.
The study found that polyester posed the most significant risk as the virus survived the entire 3-day test period. Serious risks were also discovered on polycotton and 100% cotton. The virus lasted for a total 24 hours on 100% cotton and six hours on polycotton.

Laird pointed out that these fabrics — commonly used in healthcare professionals’ uniforms that regularly come into contact with COVID-19 patients — pose a significant threat.
“If nurses and healthcare workers take their uniforms home,” said Laird, “they could be leaving traces of the virus on other surfaces.”
To use as extra protection from COVID at home, generously spray Natucair on the intended area — clothes, sofa, the inner cloth linings of shoes, curtains, seats — until damp. But, as a deodorizer, even just a few spritzes is enough.
Natucair, which is available in the Philippines, has been marketed as a product that eliminates odors from fabrics while also killing bacteria, germs, and viruses.
The product can serve as added protection to the health protocols we have in place. You still need to wash your hands thoroughly and wear a face mask at all times and the face shield when in public.
