Compatible with Dyson DC07 DC14. Effectively blocks dust particles from flowing back into the motor area, improves filtration efficiency, and extends the life of the vacuum cleaner motor. Made of foam material, it is heat-resistant, pressure-resistant, not easy to deform, and has elasticity and resilience. One-touch design, users can easily replace it by themselves, without the need for professional maintenance personnel, saving maintenance costs. Used with a post-filter, it can further reduce the leakage of fine dust particles in the air and improve the overall air purification ability., Manufacturer: OTOTEC
