Frequently asked questions

Delivery/Subscriptions »

Should I replace every 4 or 6 months?


You set up the frequency according your own personal circumstances. The effectiveness of the activated charcoal will depend on a number of variances including climate, pets, age/type of car, smoking, how frequently you operate your air conditioner, urban/rural and traffic. For example, a person that drives a diesel car mainly in built up areas with a dog in tow would benefit from replacing the box every 4 months. And remember, if there is any unspent activated charcoal in your box, you can scatter it in your garden and still benefit from the removal of toxins from your soil while ensuring you continue to have clean air in your car.




Can I cancel my subscription?


Yes, you can cancel your subscription at any time. Your refund amount will be worked out after deducting the standard unit cost and postage for any items you have already received. We will email you a reminder prior to the delivery date of your next replacement. As long as we receive your cancellation before this date, it will be effective immediately. If you cancel after the delivery has been sent, it will be effective before the next scheduled delivery.




How long will delivery take?


Your box will be dispatched within 48 hours from receipt of the order and will be sent via Royal Mail, second class. Please allow up to 7 days to reach you. For international deliveries, please see our delivery page for more options




How will I know when my replacement is due?


You can manage and cancel your subscription at any time by logging into your account. We will email you a reminder 7 days before we send out the replacement so you will have plenty of time to make any changes should you wish to pause or cancel.




What is the delivery cost?


In the UK, there is a flat delivery rate for Royal Mail second class but for international delivery, there is a sliding scale based on the number of items in the package. Please see our delivery page for more information.





About Activated Charcoal »

What is the difference between Activated Charcoal and Activated Carbon?


There is no difference – activated carbon is the term more commonly used in the commercial sector.




What is the difference between activated charcoal from Coconut vs Bamboo?


The main difference is in the porosity. Both have big cavities, but coconut activated charcoal has lots of micropores and is 3-4 times more effective than any other type for air and water purification. Read up on our complete guide to activated charcoal for more information.




What are volatile organic compounds (VOCs)?


Volatile Organic Compounds, or VOCs, are common chemical compounds that evaporate into gasses at room temperature, compromising air quality of the air we breathe. A large majority of VOCs are from manmade chemicals used in the manufacture of typical household products and in synthetic car interiors. More information on the VOCs in your car can be found on our page Vehicle Indoor Air Quality.

Other activated charcoal products last for 2 years with monthly reactivation in the sun so why can’t I do the same for Airbon?


All independent research we have seen indicate that charcoal can, indeed, be reactivated by temperatures above 600 degrees celsius (or it can be chemically reactivated). This is immensely hotter than the heat from a sunny day or in a domestic oven. If toxins adsorbed can be released by the sun, then imagine what would happen inside your car when parked in the sun. The activated charcoal would be repeatedly adsorbing and releasing these very same toxins back into the confined space of your car rendering it ineffective.




Can Airbon also remove the smell of cigarettes, pets and stale food from my car?


Absolutely, but please bear in mind that if the car is exceptionally smelly, you may need to double up the number of units. If you are a heavy smoker, you should open the window to keep the smell outside as much as possible.




Where is the best place to put the Airbon box?


You can put the Airbon box anywhere in the car but for optimum adsorption, we recommend placing it on the dashboard using the stick-on pads to stop it moving. Use minimal pressure to stick it in place.

The space between the dashboard and the windscreen is where heat penetrates most, warming the air thus making it lighter and allowing toxins, moisture and odours to settle here more freely. Placing the box on the dashboard will get the most out of the activated charcoal.




How do I dispose of the used box?


The great news is that this is fully recyclable. Once charcoal has adsorbed the pollutants, it will not release it again unless exposed to heat at 600+ degrees celsius or a chemical treatment. This means that it is safe to scatter the used charcoal into your garden so if there is any capacity for more adsorption, it can continue to work on the toxins in your soil. The wooden box can be recylced or thrown on the compost heap




I can't smell anything so how do I know it is working?


Airbon isn't an air freshener or perfume, both of which mask smells for a short period of time by releasing chemicals into the confined space of your car. This only works for a few hours, then the smell will be back. The activated charcoal in Airbon is non-scented and is a natural adsorber which removes chemicals and odours, leaving the air clean. It will continue to work until the surface area of the charcoal is full of adsorbed toxins. You probably won't notice the difference until around 2 weeks of opening the vacuum packaging. We know it works as we tested a 4-month old used box for adsorbed Benzene. The results will surprise you!




How often should I renew my Airbon box?


We recommend replacing the Airbon box every 4-6 months. This timelag allows for variances in climate, pets, age/type of car, smoking, how frequently you operate your air conditioner and traffic. The more fumes, moisture and odours, the more frequently it will need to be replaced. Once it stops being effective, you are no longer benefiting from the ongoing removal of toxins. For more details on what you are breathing inside your car, take a look at our page on Vehicle Indoor Air Quality.




If I use Airbon, does this mean I don't need to worry about replacing my car filter?


Unfortunately not. Activated Charcoal will remove chemicals and odours which is the feature lacking in cars with basic or HEPA cabin filters - these filters focus on removing particle matter which is still essential for clean air. The Airbon box helps remove pretty much everything except particle matter. Remember to replace your cabin filters every 12-15,000 miles and the Airbon box every 4-6 months to provide the cleanest air possible for you and your family
