(Note:Please confirm the vacuum cleaner model before purchasing) [Exhaust filter filters tiny dust particles to clean the air] The filter is made of high-quality filtering materials, and filters tiny dust particles such as dust, bacteria, smoke particles, pollen and mold from the exhaust gas of the vacuum cleaner. [Washable] The filter of the dust box is washable, so it can be used for a long time (gently wipe off the filter in advance to remove rough dirt). Precautions for replacing the filter: Do not insert the filter in the dust box unless it is dry. Since the filter set contains two filters, you can use the second filter and clean the first filter at the same time. [Remedy] The exhaust filter should be replaced at least once a year, because the engine needs exhaust cooling to ensure that the exhaust is always clean, avoid overheating of the engine, and ensure good air intake through constant air flow.<br><br>Colour:Black Material:Plastic<br><br>Package Contents: 2 * front filter 2 * rear filter 4 * filter cotton 1 * cleaning brush<br><br>Only the above package content, other products are not included.
