Smart Air Sqair Air Purifier Replacement Carbon Filter

Pair your HEPA filter with a carbon filter for cleaner air in your home. An activated carbon filter captures odours and gases, such as volatile organic compounds (VOCs). These compounds include harmful gases like formaldehyde and benzene and can cause cancer, throat irritation, dizziness, and other side effects. The carbon filter mesh comprises many carbon granules that have been treated to become highly porous. This means that they have enormous surface areas. Just 1 gram of activated carbon can have a surface area of between 500 to 1500 m². This massive surface area allows the carbon granules to trap harmful gas molecules, giving you that cleaner, odourless, chemical-free air.

The Sqair carbon filter screen is inserted below the HEPA filter, capturing dust and lint, allowing the HEPA to last longer. The lifespan of the carbon filter depends on the air quality around you, typically 1-3 months. One way to determine when to change your charcoal filter is to conduct a "smell test". After 3 months of use, you can do this by taking the filter out every 1-2 weeks and smelling it. If it gives off a metallic or acidic smell, it is saturated with VOCs, and it is time to replace it.
