You will benefit from a Carbon/Activated Charcoal filter if: you have recently repainted or renovated your home with new floorboards or new furnishing; you smoke or there are other offensive odours in your home; your neighbours burn wood frequently; you live a heavily polluted area.

Activated charcoal is the perfect purifier with well-developed pore structure and a huge surface area in which to capture and retain toxins. When polluted air passes through the charcoal filter, harmful gases such as formaldehyde are adsorbed into the pores and will only be released in temperatures off 600+ degrees Celsius.

The lifespan of the charcoal filter is variable as it is dependent on the quantity of VOCs adsorbed in your space. One way to find out when to change your charcoal filter is to carry out a ‘smell test’. You can do this after 3 months of use, by taking your charcoal filter out every 1-2 weeks and smelling it. If it gives off a metallic or acidic smell, then this means it is saturated with VOCs and it is time to replace it.

The Sqair air purifier works with either HEPA or Activated Charcoal filter, or both. If you purchased The Sqair Chemical Warfare and you no longer need a charcoal filter, it can be used with just the HEPA filter.

Our filters are sent via Royal Mail - 3 to 5 working days, except when ordered with a purifier (see purifier for courier details). All orders arriving before 11am (Mon-Fri) will be shipped out on the same day.

How do I get it to work better for reducing odours and fumes?
If you have a particularly smelly room - run the purifier with just the carbon filter. We recommend to keep the carbon filter in the purifier until the carbons are spent and then don't replace the carbon filter if you no longer need it. New flooring and furniture can off-gas for up to two years. If you choose to only run the carbon purifier for a week and then hold it for another time, please be aware that unless the filter is vacuum sealed, the carbon will still be adsorbing toxins but at a slower pace with no air movement.

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 Lifespan of the Carbon Filters?
It’s very difficult to give a single number for the lifespan of carbon filters, as it depends greatly on the VOC levels inside your home. These vary greatly between different homes. For example, in homes that have recently been renovated or have new furniture, the VOC concentrations will typically be higher than those that have not. That’s why we recommend determining when to change your carbon filter based on your individual situation – you can perform a carbon filter ‘smell test’ by taking your carbon filter out and smelling it every 1-2 weeks. If it gives off a metallic or acidic smell, then this means it is saturated with VOCs and ready to change. We don’t recommend trying to clean the carbon filters, unless there are large dust particles or pet hair on it

It is normal to receive a carbon filter with broken carbon parts?
The carbon filter is filled with granulated activated carbon. During the delivery process, shaking and friction during transportation may produce some activated carbon powders. Simply remove them just gently shaking the carbon filter, and carbon powder will not appear during subsequent use

Can the carbon filter be reconsituted in the sun?
No, we have not found any data or research that confirms that the toxins can be released in temperatures under 600 degrees celsius which can only be carried out in industrial plants. To prolong the filter’s lifespan, avoid placing the filter in a moist environment. See above question on the lifespan of your carbon filter

How much charcoal is in the filter?
The Sqair carbon filter has 140g of granulated activated charcoal.
