Electrostatic adsorption for durable filtration The filter uses an electretbased process to create a longlasting electrostatic charge that actively captures dust in the air. Filtration remains stable even when the air conditioner operates at low wind speed. Washable and reusable The filter can be washed with water directly and will retain performance after drying. Reusable 510 times, providing about 70% cost savings compared with disposable filters. Environmentally friendly and economical. Secondmount design for easy installation Mounting options include snaps, magnets, or Velcro. Designed to be installed by hand with the air conditioner panel open—no screwdriver needed and minimal steps. Low wind resistance without sacrificing performance Engineered to reduce wind resistance while maintaining filtration efficiency. Helps prevent a reduction in the air outlet, so cooling and heating performance remains comfortable. Use scenarios Home living room or bedroom: maintain cleaner air while running the conditioner at low fan speeds for energy efficiency. Office or study area: filters dust effectively without compromising airflow during extended use. Dorms or apartments with regular dust exposure: reusable design lowers ongoing replacement waste and cost. Notes Function: electrostatic filtration and dust capture. Compatibility: mounting through snaps, magnets, or Velcro; installation with panel access. Size and material specifics are not provided here; refer to packaging for exact fit.
