A WooS wick is the replaceable part that carries the aroma. When should you change it? Start with the condition of the aroma and the instructions for your model. WooS manufacturer guidance gives an estimate of around two to three days per wick, depending on use, not a guaranteed lifespan.[3]
Frequency of use and storage affect that estimate. A wick does not have to last exactly three days, and weaker aroma by itself does not establish that the reusable device is broken.[3]
Separate the wick from the device
WooS distinguishes the reusable device from the wick, which is replaced as the aroma decreases.[3] They do not have the same replacement cycle. If the aroma has faded, checking the wick is a more useful first step than immediately ordering another device.
Read the exact refill title and compatibility information. The WooS V1 and V2 replacement wicks are listed separately from the device.[3] Do not assume they also fit a Mini or another model; confirm your specific model with support.
When should you consider a replacement?
Use fading aroma as a practical cue alongside the product instructions. WooS manufacturer guidance says to replace the wick when its aroma has decreased.[3] You can note the date you started using it if you want to compare your own experience more consistently.
That note is not a dose record or a measure of health effectiveness. Strong aroma does not show that a device will help you stop smoking. Fading aroma is not a reason to inhale more often or more deeply to chase the same sensation.
How to store WooS wicks
Keep them in a cool, dry place away from heat and direct sunlight, following WooS manufacturer guidance.[3] Choose a consistent storage spot so the product is easy to identify and is not mixed up with unrelated items.
For the device itself, follow the care instructions supplied with your model. Do not improvise soaking, heating, chemical cleaning or modifications from general internet tips. This guide does not prescribe an unverified cleaning fluid or sanitising method. If the instructions are unclear, ask support before trying a new method.
Can you add your own essential oils?
No: WooS manufacturer guidance advises against adding other essential oils to the wick.[3] Use the replacement specified for your model rather than trying to revive an old wick with a different liquid.
Do not assume an oil sold for a diffuser, massage blend or another product is compatible with WooS. Do not add vape liquid or a homemade mixture. The Tisserand Institute's general safety guidance emphasises that essential oils are powerful substances that can cause harm without due care; it does not assess WooS formulations or establish a safe direct-inhalation schedule.[5]
What if the aroma seems weak from the start?
Check the basics: does the received item match the order, is it listed for your model, when was the packaging opened, and how was it stored? These details help support investigate without assuming the cause.
Prepare your order number, product name, date first used and photographs if available. Distinguish a scent that does not suit your preference from a wrong item or visible physical defect. These are different issues; a replacement is not automatic before the case has been reviewed.
If use causes discomfort, stop using the product and seek appropriate advice rather than experimenting with more exposure. If your main concern is quitting smoking or vaping, speak with a doctor or pharmacist; a wick-care guide is not a treatment plan.
Keep the next step simple
Remember three things: two to three days is an estimate, storage matters, and you should not add your own oils.[3] If the basic checks do not resolve your question, contact WooS support before buying parts you may not need.
For the wider picture, read how WooS works, compare models and materials, or use the wooden vape alternative guide to check what belongs in a first purchase.
Frequently asked questions
Must I replace a wick after exactly three days?
No. The two-to-three-day figure is a user-dependent estimate, not a fixed deadline or lifespan guarantee.[3]
Can I top it up when the aroma fades?
Do not add your own oils. Follow the manufacturer's replacement guidance instead.[3]
Do V1/V2 wicks definitely fit Mini?
Do not assume that compatibility. Ask about the exact model before ordering.
