Dreame AP10 Pet Air Purifier ZDNET's key takeaways The Dreame AP10 is a smart air purifier available for $300 with a 25% discount. Most particles will get stuck on the prefilter and never reach the replaceable filter, so your replaceable filter stays cleaner for longer. This lets you adjust the air purifier settings, turn on the ambient light under the table, and more. ZDNET's buying adviceThe 'cat seat' along the top of the air purifier is textured to provide better grip for pet cats. If having a HEPA filter is important to you, especially if you have health issues that require maximum air filtration, I'd look into other air purifier options, such as those from Air Oasis or Levoit.
