Each scent last 60 days, more than any other freshener in the market. Reason is that we use gel solidification technology as others use volatile liquids and Styrofoam scent sticks that are unsafe and ineffective. Plus you receive 3 scents in your starter pack which will last a total of 6 months. You can order refills after you've exhausted your scents in a 3 pack with the scent of your choosing.
Made for Long Drives and Adventures.

Your Questions, Answered.
How long does each scent last?
What is the push start stop switch?
You can turn off your diffuser to reduce unnecessary consumption and increase scent longevity. We care a lot about the environment and sustainability.
Will the Smul diffuser remove cannabis and cigarette smell?
YES, as long as you're not continuously smoking in the car. Smul scents contain a plant based nano-purification factor that is very effective in decomposing lingering cigarette and cannabis odor from the car upholstery.
Where do I install the freshener?
As you saw from our video, you open the back metal magnet and put in the gel scents. Once placed, you install it on your car air vents using the silicone vent clip.
