Air purifiers promise to improve indoor air quality by removing pollutants and airborne pathogens – they can even reduce odor. But do they work against smoke odor? What about weed smoke? Air purifiers come in many shapes and sizes for all applications, and some are quite effective in removing odor from smoke. In this guide, we’ll review how air purifiers work, whether they work for weed smoke, and which one is the best air purifier for weed smoke.

With so many air purifiers on the market, it’s hard to know which one might work best for your needs. Fortunately, we’ve done the market research to bring you our top picks here.

Benefits of Using an Air Purifier

If you suffer from asthma or allergies, maintaining high air quality in your home could be a key concern.  While air purifiers are great for removing pollutants and airborne pathogens, they can provide other benefits as well such as reducing odor.

Here are some of the potential benefits of air purifiers:

  • Removes harmful chemicals like nitrogen dioxide from the air in the home.
  • Helps relieve symptoms of asthma and allergies by removing pollutants like dust, pollen, and pet dander.
  • Neutralizes unpleasant odors from smoke, cooking odor, or volatile organic compounds (VOCs).
  • May reduce the risk of contracting airborne diseases by eliminating bacteria and viruses from the air.
  • Could help remove harmful radon gas or asbestos particles from the home.

The efficacy of an air purifier depends on the type of filter technology it utilizes. An air purifier equipped with a HEPA filter can remove 99% of airborne particulate matter or more. The type of filter also determines the size of the particles it can remove. Many air purifiers incorporate a prefilter to catch large airborne particles and an activated carbon filter to help neutralize odor.

Do Air Purifiers Work for Weed Smoke?

Air purifiers typically consist of one or more filters along with a fan. The fan draws air into the device where it passes through the filters before being released back into the home. Depending on the type of filter, air purifiers can remove large particles like dust and pollen as well as smaller particles like bacteria. Air purifiers also help maintain proper air circulation in the home.

Though there’s no denying an air purifier can work to improve indoor air quality, you may be wondering if you can use an air purifier for weed smoke. First, let’s discuss why you might be interested in using an air purifier for weed.

In addition to having a strong odor, weed smoke contains contaminants that might negatively impact indoor air quality. Marijuana has a higher water content than tobacco, so the smoke gives off both solid and liquid particulate matter. Over time, these particles can accumulate in the lungs and impair function. Weed smoke may also contain volatile organic compounds (VOCs) which can be harmful.

So, do air purifiers work for weed smoke? It depends.

As is true for any air purifier, the efficacy depends on the type of filter technology. Air purifiers that use carbon filters help remove VOCs and may have some impact on odor, but the bet option is a combination of carbon and HEPA filtration. The carbon helps eliminate VOCs from weed smoke while the HEPA filter removes particulate matter from the air.

Not all air purifiers are capable of handling both solid particles and gaseous pollutants, so it’s important to know what you’re looking for before you start shopping. We’ve rounded up some of the best air purifiers on the market to give you a few options in a good smoke purifier for weed.
