We appreciate you sharing your feedback. Our filters are estimated to last about 6-8 months, with the lifespan dependent on the current air quality as well as how often the unit is run. Exposure to excessive fur, dust, or smoke may also saturate the filters more quickly. If you have any questions or concerns about our filters, do not hesitate to reach out to us directly. Our contact information can be found in the manual. We are here to help!
