What’s the difference between a carbon filter and an activated carbon filter?

The Winix model AUS-5500 has a standard charcoal carbon filter, which effectively removes typical odours such as cooking smells, stale air and pet accidents.

The Winix model AUS-9500 has an activated carbon filter made from palletised coconut wood with massive surface area and high absorbency properties. In addition to removing typical household odours, this filter also neutralises harmful VOCS (volatile organic compounds) such as formaldehyde, ammonia and other hazardous vapours and gases. This model is ideal for people suffering from chemical sensitivities.
