Activated carbon for air purification
Smoke is a mixture containing many different compounds. Some of them are toxic while some have bad odour. When you’re smoking cannabis, the smallest molecules of the smoke find their way into your upholstery, furniture, sheets and curtains. They stay there for a long time, slowly seeping back into your apartment, causing bad odour. Because they are released back into the air very slowly, most conventional methods of neutralising them never really work.
The only type of filters that really neutralise odours, are activated carbon filters. While most methods work with concealing the odour, activated carbon absorbs and neutralizes molecules of smell. Activated carbon can be found in almost any industrial process where release of toxic gases could be damaging to the environment. Indoor air purification with activated carbon is therefore the most appropriate choice for the neutralisation of odour and irritating compounds and for general air quality improvement. Activated carbon has many different functions:
- Removes mould and bacteria
- Neutralises irritants found in smoke
- Neutralises smoke odour
- Reduces enviromental smoke effects

How does activated carbon work?
Activated carbon is manufactured from charcoal in a process called activation. This process opens up the pores inside and makes the charcoal extremely porous. Just 50 grams of activated carbon have an internal surface equivalent to a surface of 10 football fields and there is 1500 g of activated carbon in the 420 Purifier. The porous structure behaves like a sponge absorbing molecules from the air. Activated carbon is able to purify smoke of many toxic substances such as ammonia, benzene, formaldehyde, nitric oxides and VOC’s (Volatile Organic Compounds) which represent a vast majority of molecules that we perceive as smell.
What is the lifespan of activated carbon filter in 420 Purifier?
Lifespan of activated carbon filter in 420 Purifier is approximately one year if the device is used on a daily basis. Of course this is just an estimate, since it can differ with how many hours per day it operates and how much smoke it filters. If 420 Purifier is only used several times a week, activated carbon can last up to three years.
Are carbon air filters safe?
Activated carbon is made from coconut shells, which are 100% natural material. Because it is activated only with the help of steam and heat, no dangerous chemical substances are used in the process. Carbon air filters therefore only absorb chemicals from the smoke, but don’t release anything back into the air.
