I’ve had it for a few weeks and it works well. Getting the hepa filter out to take the bag off was a little difficult the first time. The smell neutralizing could be a little better but over all I am very happy with my purchase. It filter the smoke out of the kitchen from cooking on my cast iron really quickly. The pet smell has definitely improved , we own 3 Rottweilers.
Got this to replace an old HnyWl that was outdated. Just pulling it out of the box i knew it was a powerhouse. I was surprised that it immediately read 100% and was concerned ab accuracy. However when we had something overflow in the oven, causing some smoke, it immediately went to 0 and you could see it slowly come back as the air got cleaner.
Also, love that it doesn't take 3/4 filters that have to be replaced immediately after installing.
Also, I am a huge Shark/Ninja fan and slowly replacing everything we can with their products. Haven't made a bad decision on that to date!
It isn’t working. Looking for a filter. Bought this one about a year ago and can’t figure out where to purchase a filter. We had a Dyson and it doesn’t work at all
No, I would not recommend this to a friend.

Was really hoping this would solve our problems so we bought 2 units. Been running for about 3 weeks now and no change in air quality. Have noticed fine dust building up on the air purifier. Only noticed the air quality dropped when I burned pecans on the stove. Other than that it’s stays on 100% even with 2 bigs dogs in the house.

Worked great for 6 months, filter is supposed to last 5 years and I cleaned the outside filters regularly and both are already not working because I need new filters for my big one and the small one I got for my bedroom.

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.
