Hello @Nguyen0,
Great to hear you received a free Carbon Monoxide detector. As @Dede0 said, it is not possible to request this here in the Community Center as this is for community discussion and is not managed by any of the Airbnb Support Team.
I would recommend you contact Support directly to see if this will be possible, if you use the search bar at the top of the page or take a look at the Community Help Guides (created by hosts here in the CC) you will find some information on how to do this. 🙂
Lastly, just to say as you post is publicly visible, I have to remove any personal information included in your post, therefore I have removed your email address from your post above due to safety reasons.
