The machine itself is identical—only the filters are different.
The “Without Carbon” version comes with four pre-installed EPA11 filter panels. These filters provide 95% single-pass filtration efficiency for 0.3-micron particles. Because they have lower resistance, they cause less airflow loss, deliver higher CADR, and therefore purify faster. They contain no activated carbon and are designed for solid particulate matter only.
The “With Carbon” version includes EPA11-grade filters plus activated carbon: 120 g per panel, 480 g total. The activated carbon removes VOCs and odors.
Both filter types are exactly the same size, which means that when you order replacement filters in the future, you can choose the model that better suits your actual needs.
