How to make your own freshness: DIY toilet paper roll diffuser

Spray air fresheners often hit harder than necessary, leaving a faint scent and a stuffy room. The cardboard tube from a toilet paper roll can be repurposed as a passive, battery-free, plastic-free diffuser. Its dense cellulose absorbs essential oils and releases their fragrance gradually, avoiding sharp fluctuations in concentration. Start with a new roll of toilet paper. Apply 3-5 drops of essential oil to the inner surface of the cardboard tube. Ensure the oil does not contact the paper layers directly to prevent stains and potential skin irritation during use. Then, simply install the holder as usual. The Science of Scent Diffusion The mechanism behind this scent dispersal is straightforward: as the roll turns, microscopic air currents are generated. These currents carry the scent molecules throughout the bathroom. It's a passive yet continuous process.
