Samsung Compatable Micro Dust Filter The Micro Dust Filter captures the smallest particles of dirt and allergens. A Micro Dust Filter plays an integral part in the life of your vacuum cleaner. Its purpose is to collect the dust that passes through the suction nozzle, helping prevent dust particles from being spread around the room. If your cleaners filter is clogged while in use, then suction power may decrease and a vibrating sound may be heard. In addition, the vacuum motor can become overheated if the dust particles are not filtered out and make their way into the motor. This replacement filter can be washed, dried and used again. This extends the life of the filter and helps reduce the cost of running your vacuum cleaner. IMPORTANT: Failure to clean your filters may result in air blockage, overheating and reduce the suction of your vacuum cleaner. Cleaning and replacing your filters regularly will help to maintain its best performance. Please check model fit list to ensure this
