NGB Smoke-Stop Filter Replacement for Blueair 400 series
The SmokeStop Filter is suitable for the 400 series and the perfect choice for allergy sufferers and other health-conscious individuals that need high-efficiency PM2.5 or better particle removal, but also require gas and odor control.
The NGB SmokeStop filter is a progressive carbon filter with a honeycomb-type structure that improves airflow and has hundreds of odor and gas absorbing carbon pellets.
The carbon eliminates volatile organic compounds (VOC), which are responsible for odors.
NGB filters present great advantages compared to their predecessors!
They are lighter than before, more efficient in removing VOCs, and HEPA filter and activated carbon filter are detachable from each other.
