Replacement Filter for Shark ION Robot Vacuum RV850 Series

Q: How often should I replace the Shark ION Robot's filter? A: About every 2 to 3 months with regular use. Weaker suction or a musty smell are both signs it's overdue. Q: Does this fit the Shark IQ or AI robot series too? A: No — this filter is specifically sized for the ION RV850/851/852 series. Shark's IQ and AI robot lines use a different filter shape. Q: Is this a genuine Shark part? A: No — it's a third-party compatible filter, not an official Shark-branded one.
