General description 100% brand new and high quality HEPA filter designed for Miele TriFlex HX1 FSF vacuum cleaners. Made of high-strength environmentally friendly materials, this filter effectively blocks most dust particles down to 0.3 micrometers, maintaining optimal cleaning performance while reducing the penetration of dust, pollen, and other allergens into the air. Technical specifications Material: Plastic Color: White Filter size measurement error: +/- 1-3 cm Installation Remove the dust container by grasping it firmly and pulling it outwards. To empty the dust container, find the release latch, pull it open, and empty it. Remove the old filter and insert the new filter back into the dustbin. Usage For best performance, change the filter at least every 3 to 6 months, depending on the frequency of vacuuming and the amount of dirt cleaned. A dirty filter will significantly reduce suction power. Other information Package Contents: 2 x Filters, 1 x Cleaning Brush Note: Light
