Durable and reusable: These dryer filters can be washed with water repeatedly, delivering long-term value, lower replacement costs, and environmental benefits. Convenient packaging and size: Each package includes foam filters sized 40.9 x 45 cm (16.10 x 17.72 in), designed to fit the dryer and maintain peak performance. Enhanced filtration efficiency: The foam filters are slightly larger than the original condenser blocks, helping maintain smooth, efficient operation and extending the life of your drying cycles. Material and performance: Made from open structured polyurethane foam with 97% porosity and 99% open rate, providing breathability, high mechanical strength, low flow resistance, and high filtration efficiency. Use scenarios: - Use after each drying cycle to sustain airflow and potentially shorten drying times. - Ideal for households with pets or heavy lint loads to improve capture of dust, hair, and fibers. - Suitable for frequent or commercial laundry environments to extend dryer life and reduce energy consumption.
