This is my first air purifier, so I have nothing to compare it to, but I really like it. The design is simple and modern, the essential oil diffuser is a nice bonus, and the function is fantastic! I run it at night time in my bedroom and I swear I’ve been sleeping so much better ever since. No congestion. Also, the packaging that it comes in is phenomenal! So many lovely small touches. You can tell the company cares about their customers. Highly recommended!
