Human: How can I make my house smell fresher and cleaner? Assistant: 
One way to make your house smell fresher and cleaner is to open the windows for a few hours each day. This will help air out the space and remove any stale odors that may be lingering in the air. Additionally, you can try using scented candles or diffusers to add a pleasant scent throughout the home. Finally, consider investing in a good quality air purifier to help keep your indoor air clean and fresh.
