No electricity required, no extra space occupied, the Gunrid The curtain from IKEA looks like an ordinary curtain but fulfills a new function – it purifies the indoor air as it is infused with the latest technology from the HeiQ Fresh range – HeiQ Fresh AIR. Gunrid curtains will be available in IKEA stores in 2020.

HeiQ explains: “According to the World Health Organization, more than 80% of city dwellers are exposed to high levels of air pollution1. The concentration of VOCs indoors is generally higher than outdoors2. While many VOCs are not considered harmful to health, like perfumes and fragrances, others like acetaldehyde, formaldehyde, nitrogen oxide (NO) and d-limonene and Other semi-volatile polycyclic aromatic hydrocarbons are attributed as responsible for a significant negative impact on health by the World Health Organization (WHO).

“These VOCs come from outdoor sources as well as indoor sources such as furniture, paints, household cleaning products, sprays or cooking activities, as reported in the 2018 Clean Air Survey, conducted by IKEA. With the aim of improving people’s lives by making everyday textiles more functional, HeiQ has innovated a textile treatment that will use home fabrics such as curtains as a backing to purify indoor air.

14 years ago, the foundation of the Swiss company was inspired by the bad odors on polyester hiking clothing. The HeiQ Fresh product family has evolved into a complete textile solutions platform that achieves “freshness” by tackling both odor-generating sources and reducing VOCs. This latest innovation focuses on odorless and potentially harmful VOCs and the research result – HeiQ Fresh AIR – adds a new dimension to the HeiQ Fresh range. This technology will first be available on the market on IKEA’s Gunrid curtains.

“With HeiQ Fresh AIR, we aim to easily improve the air quality in consumers’ homes, simply by hanging up a curtain and using the natural light coming through the window. A simple tool for something so important, the fresh air in your home, ”says Carlo Centonze, co-founder and CEO of the HeiQ group.

How it works?

HeiQ Fresh AIR is a Swiss mineral-based technology infused into curtain fabrics. It purifies indoor air by using transmitted ultraviolet (UVA) light from the sun to turn problematic VOCs into components of fresh air. Curtains and other upholstery fabrics infused with HeiQ Fresh technology therefore contribute to better homes with cleaner air.

How is air purification performance measured?

Creating disruptive technologies for 14 years, HeiQ emphasizes the importance of identifying the correct testing methodology and creating standards to help brands, factories and consumers interpret the performance of a new technology. Working closely with Prof. Dr. Detlef Bahnemann, Head of Photocatalysis and Nanotechnology at Leibniz University in Hanover, Germany, test standards were selected capable of characterizing the air purification performance of fabrics infused with HeiQ Fresh AIR. Internationally recognized standards: ISO 22197-1 for NO and ISO 22197-2 for acetaldehyde, ISO 17299 modified to measure the percentage reduction of VOCs as well as ISO 10678 modified as a quick quality control test for factories.
