How do I maintain my apartment to smell like new?

Hi! First of all, I apologize for my English, it’s not my native language.

I’m pregnant, 33 weeks and I loooove the smell of my new apartment. It smells clean, like the smell of new furnitures, it smells fresh and I want to keep it that way, I don’t want overwhelming scents. Can you help me how to maintain this smell? It’s certainly don’t smell like strawberries or lemons, but smell of a brand new furnitures. I don’t even know how to describe lol.

Any tips how to keep my apartment smell clean and fresh?
