Hi there, Thank you for taking the time to leave a review. We’re truly sorry to hear that you're experiencing issues with your Shark air purifier, and the filter needs replacing after only 6 months. We understand how frustrating this can be, and we appreciate you bringing it to our attention. Please know that we will share your feedback with the appropriate internal teams. To help maximize your air purifier’s performance and extend filter life, Shark recommends keeping the unit in AUTO mode. Once 100% clean air is maintained for 10 minutes in AUTO mode, the purifier will automatically enter ECO mode to further optimize filter efficiency and longevity. Additionally, to help extend the life of the HEPA filter, we recommend reorienting it every three months. Simply remove the HEPA filter, turn it upside down, and reinsert it so the side that was previously on top is now on the bottom. This helps evenly distribute captured particles throughout the filter and supports longer‑lasting performance. In the meantime, we suggest reviewing our self‑help troubleshooting guide below for assistance with the issue you’re experiencing: https://support.sharkninja.com/article/HP300-Series-Shark-NeverChange-Air-Purifier-MAX-Troubleshooting-Guide If the issue persists after following the suggested steps, please refer to the instructions at the end of the guide to contact our support team.
