It’s also worth considering the other air purifiers in our review as they all come with different features that could be useful in getting rid of weed smoke in your home.

Buyer’s Guide On Air Purifier for Weed Smoke Smell


An activated carbon filter air purifier weed is one of the best ways to remove the smell of marijuana from your home. This is because activated carbon filters are fantastic for capturing the pollutant particles that cause odors, which includes weed smoke. 

The air purifiers in our review that come with both activated carbon and true HEPA filters are the most effective machines at dealing with weed smoke. True HEPA filters can get rid of 99.97% of pollutant particles that are as tiny as 0.3 microns. 

As a result, the combination of an activated carbon and true HEPA filter, your air purifier can remove the odor and leftover pollutant particles that are caused by weed smoke being airborne. 

We’ve also included reviews that include air purifiers with additional filters, such as ones that are specifically made to capture more odors. These types of air purifiers could be worth considering if weed smoke is regular in your home. 

CADR Rating (Clean Air Delivery Rate)

CADR (Clean Air Delivery Rate) lets you know the amount of air that an air purifier can clean every minute within a certain space in cubic feet. It’s a factor that you can use when comparing different air purifiers together as you can see which ones have a better CADR rating to improve the cleanliness of the air in your home. 

The air purifiers that come with a CADR rating below 100 are usually the cheap options and are best to consider for those on a tighter budget. However, we recommend finding air purifiers to get rid of weed smell to have a higher CADR rating of 150-200+. 

Room Coverage

It’s critical to know the size of the room that you’re planning to use your air purifier in. This helps you to pick an air purifier that has been made to properly fit the space that you’re looking to install it in. 

Air purifiers that are meant for smaller rooms can still clean the air in rooms that are larger than they’re intended for. Although, there will still be a lot of pollutant particles in the air. Therefore, using an air purifier that can properly clean the air in the space that you have will be much more effective at removing cannabis smoke particles.

ACH (Air Changes per Hour)

ACH (Air Changes per Hour) is another important aspect to think about. The ACH rating provides you with information based on the number of times that an air purifier can clean the air within a room.

An air purifier that’s able to clean the air in a room 3x or more would be best. If you’re on a tighter budget, the inexpensive air purifiers may have lower ACH ratings which means you should manage your expectations.

Air Purifier Size

Deciding on the size of your air purifier will depend on the ways that you want to use it and the amount of space that you have available.

If you wanted a machine that you could use to clean the air in different rooms throughout your home, you may want to consider using a portable option. These air purifiers are smaller in size and can be easily moved from room to room.

For those of you who have limited space, you may also want to consider more compact air purifiers. This is because you can set them up and save on space. On the other hand, when it comes to larger rooms, a bigger air purifier will have the capacity to properly fill the room. Therefore, if you’re interested in using an air purifier in a bigger room and you have the additional space, using a larger machine won’t be as much of a drawback.

Can weed smoke be harmful?

Smoke of any kind can pose a risk to your health when it’s being inhaled. While there has been no solid evidence on weed smoke causing damage to the lungs, experts are still not 100% certain that it’s safe to inhale. The potential of negative effects on the lungs increases the more that you smoke marijuana.

Does an air purifier help with weed smoke?

When you’re using air purifiers to remove the smell of weed, it has to deal with the odors and ash being airborne. Therefore, air purifiers with HEPA and activated carbon filters are the best options for helping with weed smoke.

The HEPA filters can remove more of the ash particles and the activated carbon filter helps to eliminate the smell of weed.

How often should you keep your air purifier running to get rid of weed smoke?

Your budget and the amount of weed smoke that’s in your air will affect how often you need to use your air purifier. For those looking to save money, you may not want to have your air purifier running all the time to save on electricity bills.

You may want to think about using the air purifiers that come with auto modes as they can adjust their fan speed and power consumption based on the cleanliness of the air in your home.

Tips On Using Air Purifier Weed Smoke Removal 

  • Be sure to maintain the filters inside your air purifier by following the instructions available with the guide. Some of them are permanent which makes it easier for you to wipe them down. Others will require replacing after several months.
  • We recommend placing your air purifier in the room where weed smoke will be the most prominent. This ensures that the air purifier can capture most of the odor before it spreads around to other rooms.
