How long does each scent last?

Each scent last 60 days, more than any other freshener on the market. Reason is that we use gel solidification technology instead of volatile liquids and styrofoam scent sticks which are unsafe and ineffective. You receive three 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 three pack with the scents of your choosing.

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 car upholstery. 

Where do I install the freshener?

Watch the video on the product and homepage. We also send instructions with your order. In a nutshell 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. 

I have allergies to perfumes will this give me a reaction?

100% asthma and allergy friendly. We use aromatherapy and pure essential oils in our gel fragrances. No artificial chemicals and perfumes are used. Our scents are SAFE for people with allergies, pregnant women and children.
