E&H, a company specializing in air filter materials, has launched 'Whistlet,' a natural ventilation window that maximizes air-purification performance, and has begun selling it on its online store (filterex.co.kr).
E&H's 'Whistlet' is a new-concept natural ventilation window that maximizes airflow using natural breezes. By applying a film-type filter based on hybrid filter technology, it delivers superior airflow compared to conventional HEPA filters and maximizes air circulation without any separate electrical device, while also enhancing dust collection—making it a fully optimized air-purification solution.
A company official said, "Whistlet was developed in a DIY format that can filter out even fine dust from outdoors without worrying about electricity bills, and that anyone can easily install and replace the filter," adding, "From now on, you can ventilate without hesitation even on days with heavy yellow dust or fine dust, so it can be used with peace of mind in places sensitive to fine dust, such as kitchens and children's rooms."
In reality, conventional air purifiers could filter indoor fine dust but made natural ventilation difficult, while similar natural ventilation windows or dust-proof screen products had unverified performance and low air-purification satisfaction. 'Whistlet' is a next-generation air filter with verified air-purification performance and the first natural ventilation window to apply the ultra-fine filter used in leading domestic air conditioners, making it a product that meets the expectations of consumers concerned about fine dust. To date, E&H has proven its outstanding product capabilities through advanced air filter material technology, developing Korea's first film-type filter 'H-Tron' and supplying it as an air-conditioner filter material to leading domestic home appliance makers. In addition, based on Korea's largest air filter production facility, the company is expanding a diverse product lineup spanning both B2B and B2C, including air purifier filters (Filterex), automotive cabin filters, and health masks (Malgeun Gonggi).
E&H CEO Hwang Gyu-ik said, "We have concentrated more than 40 years of accumulated air filter technology into the newly launched Whistlet and will serve as the solution that blocks fine dust for all consumers," adding, "Using the launch of Whistlet as a springboard, we will take the lead in the domestic natural ventilation market and continue to grow into a total clean natural ventilation solution company, not just a filter material supplier." 1522-6935
