The Andreae HH Original filter has a higher filtration efficiency while keeping low airflow resistance. This means the filter lasts longer, ensuring a reduction in maintenance costs. The HH is made out of 2 layers of heavy “kraft” paper punched, pleated and glued together, completed with a fiberglass layer increasing both the filter’s holding capacity and filtration efficiency.
