Replacement Carbon filter for The Sqair

Replacement Carbon filter for The Sqair

  • An Activated Charcoal/Carbon filter will capture odours and VOCs including formaldehyde and benzene which can be found in homes. But not all homes have dangerous levels of harmful gases or VOCs which is why we leave you to choose when you need this. You will benefit from an activated charcoal filter if: you have recently repainted or renovated your home with new floorboards or furnishing; you smoke or there are other offensive odours in your home; 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
  • Each filter contains 140g of granular activated charcoal
  • Size: 255 x 255 x 10 mm


The lifespan of the charcoal filter is variable as it is dependent on the individual circumstances and the quantity of VOCs adsorbed. 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.

We haven’t seen any research proving that activated charcoal can be reconstituted at temperatures below 600 degrees Celsius despite marketing claims on various sites. It is for this reason that we recommend replacing the filter when the charcoal is spent.

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.
