All of these air purifiers include heavy-duty carbon filtration, which eliminates harmful chemicals and odors and helps you breathe healthier.
Typically, the larger the amount of carbon in the unit, the more odors and chemical vapors it can remove from the air before the filter needs to be replaced. Some odor and chemical air purifiers also feature enhancements to remove allergen particles such as dust, pollen, and mold spores. These models give you the best of both worlds: relief from allergies and a fresher, chemical-free environment.
