You need a purifier that is properly sized to the room where you plan to place it so it can clean the entire volume of the room. Next, you need a True HEPA filter with activated carbon, which acts like a sponge to absorb smoke. The filter’s HEPA material captures dangerous fine particulate matter that can trigger allergic reactions and respiratory problems while activated carbon absorbs harmful gasses and chemicals such as Volatile Organic Compounds (VOCs).
Thus, the highest air flow and the largest absorption capacity the better.
Here are the Alen models ranked in order of capacity for smoke absorption (most to least activated carbon)
- BreatheSmart 75i with B7 Fresh filter
- BreatheSmart FIT50 with FF50 Silver Carbon (VOC filter)
- BreatheSmart Classic with Fresh Plus BF35 Silver Filter

Note: Each unit comes with your choice of filter installed. If you are experiencing heavy smoke, we suggest purchasing a spare filter because the amount of absorption you may need depends on how much smoke needs to be absorbed. Every situation is unique, so it is difficult to know when the carbon will be fully saturated.
