Candles produce an amazing scent, but the chemicals and byproducts are not amazing. My concept is to create a lamp (possibly 3D printed) that covers the candle - the light illuminating inside, while a HEPA filter allows the smell to escape without carcinogens and pollution.

Aesthetic: This lamp feature would sit anywhere while the candle inside glows: the bottom being a filter with the ability to replace it and the candle itself.
