Air Purifiers for Residential Medical Marijuana Use

What to Look for in an Air Purifier for Marijuana Smoke

When choosing an air purifier for any kind of smoke, it's critical to pick one that can reduce VOCs — this means a carbon filter or another equivalent filtration medium designed specifically for VOC reduction. A unit without adequate carbon media will struggle to keep odor under control, no matter how good it is at capturing particles.

If you're dealing with a very small space (a few hundred sq ft) and are thinking of the Airpura 700 series, a better option would be the Airpura 600 series, since it doesn't have the vortex airflow effect found in the 700 motors. The 700 series is more suited for medium to larger rooms.

How Many Air Changes Per Hour Do You Need for Marijuana Smoke?

For general indoor air quality, aim for 4 to 6 air changes per hour (ACH). But when you're dealing with a heavier contaminant like marijuana smoke, you'll want to aim higher — 6 to 12 ACH is a better target for active, high-capacity odor and smoke removal. The right number for your space will depend on square footage and how often you smoke, so it's worth choosing a unit sized with that higher range in mind rather than the general baseline.

Finding the Right Unit for Your Space

The right purifier for you depends on room size, how often you smoke, and how sensitive anyone in your household is to the odor.
