Description

Thanks to 10 years of research and 5 international patents, the Nana Captor filter is the only one that permanently destroys formaldehyde, the most harmful pollutant indoors and a human carcinogen according to the World Health Organization. Formaldehyde, an irritating gas that causes sensitization and also worsening symptoms of allergic asthma, is present in 100 percent of homes and is found in detergents, building and insulating materials, pressed wood materials or still scented candles. The yellow granules inside the filter turns red when saturated, meaning its time to replace the filter. As more formaldehyde is destroyed, the granules turn brown.
