Cons: VOC sensor accuracy, washable pre-filter
Reviewers like the pelleted or granular activated carbon for the price, but several say the carbon amount is too limited for heavy gases or odors.
Pros: durability, display readability
Cons: mold spore reduction, app connectivity
The carbon filter helped with lighter odors, but reviewers also noted it was not built for heavy smoke.
Pros: energy efficiency, power consumption
