The IAQ Virus Keeper filter, made in South Korea with Nano-Silver technology, improves indoor air quality by removing PM 2.5, toxic gases, smoke, bacteria, viruses, and mold spores. Tested in the USA, Japan, and Korea, it’s an affordable alternative to expensive air purifiers. The filter works by simply covering your existing air conditioner or fan filter, turning these devices into effective air purifiers. There’s no need to purchase additional equipment, as the IAQ Virus Keeper uses the fan’s airflow to clean the air. Ideal for commercial use, the filter can also be applied to HVAC systems by placing it over existing Air Handling Unit (AHU) filters, extending their life and improving performance. It’s compatible with HEPA filters, making it perfect for cleanrooms and spaces requiring high air quality. This cost-effective solution enhances air quality in both residential and commercial settings, without the high cost of dedicated air purifiers.
