ELFI 400-K electrostatic airpurification

ELFI 400-K is a duct filter with electrostatic purification.

The filter, suitable for all homes with air heating systems or heat exchangers, is installed in the ventilation duct to clean incoming air. The result is a cleaner and healthier indoor environment, which is particularly beneficial for allergy and asthma sufferers.

Efficient

Incoming air particles are pre-charged in the front section of the filter. They then pass through a series of electrostatic plates where they are captured. Dust, pollen, bacteria, radon daughters, soot, chimney smoke, vehicle emissions, and more are effectively removed, purifying the air by 95–100%.

Energy-Efficient

Conventional air purification systems increase energy consumption due to pressure drops in the filter assembly. In our electrostatic filters, air resistance is minimal, ensuring energy efficiency.

Silent Operation

Pressure drops in conventional filters require noisy fans to force air into the building. Our technology eliminates air resistance, making loud fans unnecessary. The ELFI 400-K provides quiet, efficient air purification.

Maintenance

Clean the filter every three months in a dishwasher or with warm water. Important: Ensure the filter is completely dry before use, with a drying time of at least 24 hours. Replace pre-filters and carbon filters as needed.
