Best air purifier for homes with pets!

I love everything about this air purifier. I cohld tell a difference in our home in day one. I use it in our living room, where we spend the most time. It connects to my phone and can easily be turned on or adjusted from anywhere, plus it provides feedback on the room's air quality. It's very quiet, it's the perfect small size, and looks nice. An added, unexpected bonus, is my dog loves laying near it! With the heat, i turn it up and allow the fan to run on high in the evenings and she loves to nap nearby. I would recommend this to anyone concerned with air quality.

Received this air purifier mid June and decided it would be best to try it in my sister's bedroom. We have a long hair cat and a golden retriever that sleep predominantly in her room and she has asthma! Since we plugged the unit in, it has been running full blast and we couldn't be more pleased! She has noticed a distinct positive difference in how she feels in the morning. It's great that they designed the unit the way they did. It provides 360° access to the air in the room. I also like that I can see the air quality readings. It's perfect for people with homes that include animals!

This air purifier helps to eliminate allergens in small spaces. I had my son test it out in his room where our pets come and go from time to time. He woke up without a stuffy nose after using it, and his room smells quite crisp and clean. It's also very quiet and has easy to use options located on top of the machine. A bonus is being able to wash the outer cover before having to replace the entire filter.

I really like this thing & my lungs do too

I have terrible asthma & obviously this filter isn't going to change that, but since I put this in my bedroom I get fewer flares, and the air feels cleaner. Plus

I have terrible asthma & obviously this filter isn't going to change that, but since I put this in my bedroom I get fewer flares, and the air feels cleaner. Plus my things get dusty a lot less quickly. I love that it's pretty quiet compared to my other air filter, and i can adjust it from bed with the app so that if it's too loud or blowing too much I don't have to get up if I'm all comfortable. Overall a good choice.

This air purifier is wonderful. It is absolutely dead quiet compared to the fan noise of other filters that we have had in the past. It seems to be doing a great job with keeping the room fresh. Would definitely recommend.
