Introduction to Air Purifiers for Weed Smoke

Our selections are based on research and testing, focusing on performance, noise levels, and the essential combination of HEPA filtration and activated charcoal to combat both particles and odors effectively.

The prices are always changing so we've linked to the official product pages on Amazon. At the time of writing they range between $150 and $800.

Replacing Your Air Filter

When choosing an air purifier for combating weed smoke, consider not just the initial cost but also the ongoing expenses of replacement filters. Much like inkjet printers, some air purifiers with seemingly lower prices have expensive replacement filters, significantly increasing their total cost over time.

Cost and Lifespan of Replacement Filters

Always check the price and lifespan of replacement filters before purchasing an air purifier. Models with expensive true HEPA air filters or those needing frequent replacements can become costly. True HEPA filters are excellent for trapping 99.97% of particles as small as 0.3 microns, including marijuana smoke, but their effectiveness decreases as they clog over time.

Air Purifier Carbon Filters for Smoke

Alongside True HEPA filters, carbon filters play a crucial role in purifying air from smoke particles and odors. Carbon filters absorb smoke and odors, making them essential for effectively cleaning the air from weed smoke. Ensure the air purifier has both a True HEPA filter and a high-quality carbon filter to handle the variety of particles and gases found in marijuana smoke.

Key Considerations for Filter Replacement

  • Frequency of Use: More frequent use and higher smoke levels require more regular filter changes.
  • Filter Costs: Compare the costs among models. Sometimes a more expensive air purifier offers more cost-effective filter replacements.
  • Warranty and Support: Look for warranties or subscriptions that offset the cost of new filters.

In summary, consider both the air purifier's price and the ongoing costs of replacing the True HEPA and carbon filters. This approach helps you avoid high long-term costs and ensures effective smoke purification.


Selecting the right air purifier for weed smoke involves a balance of filtration technology, room coverage, and additional features like noise level and warranty.

The Winix AM80 offers exceptional value with comprehensive coverage and filtration capabilities for those on a budget and just need it for one room at home.
