The Blueair 680i SmokeStop is part of Blueair’s 'New Classic' range of air purifiers and was released in January 2017. It is the follow up model of the ‘650E’ model. The Blueair 680i SmokeStop has an improved airflow rate of up to 22% - 1015 m3/h on speed setting three compared to the 832 m3/h of the previous 600 series model. The filtration technology used, size, weight and the overall look of the unit is however unchanged. What the Blueair 680i SmokeStop does offer is a new air quality monitor, a ‘hidden’ interface with touch buttons under a flip-up lid on top the unit, Wi-Fi connectability and an accompanying app.
With the Wi-Fi capability, the Blueair 680i SmokeStop air purifier, can connect with your smartphone via a Wi-Fi network and allows you to make changes to how the unit operates. This can be done via the Blueair Friend App which is compatible with Android and iOS smartphones. Just like the ‘650E’, the Blueair 680i SmokeStop air purifier has a built-in sensor designed to detect changes in VOC’s and PM2.5. In addition, the 680i SmokeStop also offers humidity and temperature sensing capabilities.
The Blueair 680i SmokeStop has Blueair’s activated carbon filtration along with the normal particulate filter for the removal of light gas and odour contamination.

The Blueair 680i SmokeStop, as with all other Blueair air purifiers, uses a Three-Stage Progressive Filter – a filter that resembles having many filters in one.
The filter is made up out of three different levels of millions of ultra thin fibers, and with its ‘lock-in’ design, once captured the particles are not re-released back into your environment, even when the filter is heavily loaded.
The first layers capture larger particles like pollen and dust, and the later layers capture smaller particles like bacteria and exhaust particles.
The 680i SmokeStop filter kit includes three filters with enhanced active carbon; one for each side that clean air is released from the unit.
Regular air purifier filters are thinner and mostly consist of the same fiber size and material throughout, this leads to them clogging up sooner. However, the unique design of the Blueair 680i SmokeStop Three-Stage Progressive Filter resists clogging, and allows the 680i to perform longer on its peak performance.
When the filter needs to be replaced (around every six months), just open the lid, take out the old filter and put the new one in. No screws, hooks or tools are needed.
