Your Questions, Answered

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 car freshener 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. 

How do I install the freshener?

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

How fast will my order arrive?

We do ship globally to the UK & Australia but expect longer shipping times of 15-30 days depending on which region you reside in. 

Do you ship to Europe and international?

Yes, we ship to the UK & Australia but not the rest of Europe & World. Expect longer ship times of 15-30 days depending on the destination. We are looking to expand to the rest of Europe in 2024.
