6 Best Air Purifiers for Weed Smoke

The legalization of cannabis has been growing in the U.S. since Colorado and Washington passed legislation for recreational use in 2012. This has opened a door for people across the country to enjoy smoking weed in their homes. Whether you use marijuana for health benefits, to relax, or to socialize, it can’t be denied that the smell lingers and is a real downside to enjoying cannabis in the home.

As the law states you can’t smoke weed in public, you can be left with the extremely potent odor in your home. The smell can differ with different types of strains, but it will still stick to clothes, hair, and furniture that will be noticeable to visitors to your home. Or you may not even smoke but be burdened with the smell that has drifted over from a neighbor. 

There are ways of minimizing the odor left from smoking weed indoors. The most effective way is to introduce an air purifier into the home. This will filter out the odor made from smoking and replace it with fresh clean air. If you’re looking for a unit to help with smoking weed indoors, you should consider investing in a high-powered purifier with a strong carbon filter. To tackle odors coming from outside, you may be able to reduce the smell with a smaller unit.

How We Picked Our Top Choices

To make sure our choices are the best for this topic, we looked into the science behind the most effective filters for weed odors and trawled through reviews and recommendations from real people who are dealing with these issues. 

Here are some things you need to consider:

  • The filter it uses
  • The amount of weed being smoked
  • The size of your room
  • Your budget

We found that air purifiers with the most activated carbon packed into a True HEPA filter are the most effective for getting rid of the odor and VOCs (volatile organic compounds) generated from smoking weed.

2. AeraMax 300

3. Blueair Blue Pure 411

4. RabbitAir MinusA2

5. Levoit LV-PUR131

6. TruSens Z-3000

1. Alen BreatheSmart Classic

Alen Breathesmart Classic, Pet Dander/Odor, White

The BreatheSmart Classic by Alen has been featured before in our lists. It’s the most expensive of our picks but for good reason. This unit is ideal for rooms up to 1,100 sq.ft. and will make easy work of cleaning air when smoking weed indoors. With four different speeds to choose from, you can crank it up when smoking with a group of friends.

There’s an option to customize the filter to get exactly what you need out of it. For weed, we suggest going for the ‘FreshPlus’ option. This three-stage True HEPA filter is packed full of activated carbon to eliminate chemical toxins and odors created by smoke, cleaning the smell of cannabis out of the air. It lasts around 10-12 months which keeps costs down. 

Not only is this unit built to be running 24/7 but it features a smart sensor on the display to indicate the quality of the air in real-time using different colors (blue for clean, red for dirty, orange for average). This will let you know when it’s time to adjust the fan speed or pop it on auto if you’re planning a session. The BreatheSmart Classic comes in several different colors so you can pick one which suits the vibe of your home.

What we love: 

  • Easy to operate
  • Ionizer produces no significant ozone

We don’t like this as much:

  • No app or WiFi technology

2. AeraMax 300

AeraMax 300 Large Room Air Purifier Mold, Odors, Dust, Smoke, Allergens and Germs with True HEPA Filter and 4-Stage Purification

The AeraMax 300 is the flagship unit from American family company Fellowes. Working at its best in rooms from 300-600 sq.ft. this unit falls into our mid-range category. There’s an easy to navigate touch screen control panel on the front to adjust fan speed and engage its trademarked Aera+ Mode which acts like a turbo mode.

The AeraMax boasts a 4-stage “hospital-type” filtration system which contains the activated carbon filter we’re looking for, True HEPA, an antimicrobial treatment that prevents the growth of odor-causing bacteria, and an ionizer that removes pollutants. We usually try to avoid ionizers as some emit harmful ozone toxins, but the AeraMax 300 is certified by the AAFA (Asthma and Allergy Foundation of America) to comply with their standards.

The 300 model comes with a smart sensor that is becoming standard practice on units at this price-point. There’s no indicator to display the quality of the air but it will automatically change the fan speed accordingly. 

What we love: 

  • American made
  • Light and portable

We don’t like this as much:

  • Basic design

3. Blueair Blue Pure 411

Blueair Blue Pure 411 Air Purifier for home 3 Stage with Washable Pre-Filter, Particle, Carbon Filter, Captures Allergens, Viruses, Odors, Smoke, Mold, Dust, Germs, Pets, Smokers, Small Room

Blueair is a well-respected name in the air purifier game. For our budget option, we’ve chosen the Blue Pure 411. This smaller unit comes in around $100 and is great for portability. The 411 is most effective in rooms up to 161 sq.ft. which means it’ll be pretty ineffective in a room filled with weed smoke, but will do the job of keeping the odor out of other rooms you don’t directly smoke in.

The three-stage filter on this guy may be small, but in the right setting works really hard. There’s a fabric pre-filter on the exterior which comes in different colors to match your style, a particle filter, and the activated carbon filter for odor-causing bacteria and VOCs.

They have sacrificed the fancy gadgetry you’ll find on mid-\high-range purifiers. There’s no smart sensor, no timer, no touch screen display. In fact, there’s only one button to control the whole unit (which is a plus when you’ve enjoyed a smoke). But the best feature on the 411 is how quiet it is. At only 17dB on its lowest setting, you’ll barely hear this unit over eating a bag of chips. 

What we love: 

  • Modern design
  • Low power consumption

We don’t like this as much:

  • No air quality display 
Blueair Blue Pure 411 Air Purifier for home 3 Stage with Washable Pre-Filter, Particle, Carbon Filter, Captures Allergens, Viruses, Odors, Smoke, Mold, Dust, Germs, Pets, Smokers, Small Room

  • Quiet operation enabled by advanced filters that allow for a higher airflow at a lower noise level. Sound level: 17 – 46 decibel
  • Designed for small to medium rooms between 100 square feet and 175 square feet. (AHAM rated at 161 square feet) make this purifier perfect for small bedrooms, offices, nurseries and dorm rooms. Air inlet: 360 degree

4. RabbitAir MinusA2

RabbitAir MinusA2 Ultra Quiet HEPA Air Purifier - Stylish, Efficient and Energy Star (SPA-780A, Black, Toxin Absorber)

Back to the high end of the spectrum is the RabbitAir MinusA2. This high tech unit can be both free-standing or wall mounted to suit your needs, comes in either white, black, or for the true artist you can get customized front panels. This purifier will cover an area of 815 sq.ft. but we recommend getting the best out of by using it in a room up to 600 sq.ft.

In terms of filters, the MinusA2 has six of them! As well as the usual suspects (True HEPA, activated carbon filter, etc.) this purifier comes with an option of a customized filter, which for our purposes, we would recommend going for the “Odor Remover”. Running this unit at a high speed with this combination of filters will clear the air rapidly when you’re smoking weed indoors.

The MinusA2 shares a few of the same features as our other picks. For example, it has smart sensors to control the fan speed if the air quality suddenly drops around 4.20 pm and has a sleep mode that turns on when the room gets dark. What sets it apart is its ability to connect to Wi-Fi so you can monitor and control everything on a dedicated app from anywhere at any time.

What we love: 

  • Low operating costs
  • Stylish looking

We don’t like this as much:

  • LED on the front can be intrusive
RabbitAir MinusA2 Ultra Quiet HEPA Air Purifier - Stylish, Efficient and Energy Star (SPA-780A, Black, Toxin Absorber)
  • Advanced HEPA filtration with six stages of purification and deodorization
  • 5 Year Warranty
  • Toxin Absorber customized filter: Traps and reduces volatile organic compounds (VOCs) and other chemicals.
  • The MinusA2 is designed to either stand alone or to be mounted on the wall.
  • Room coverage up to 815 sq. ft.

5. Levoit LV-PUR131

LEVOIT Air Purifier for Home Large Room,Smoke and Odor Eliminator, H13 True HEPA Filter for Bedroom, Auto Mode & 12h Timer, Cleaners for Allergies and Pets, Mold Pollen Dust, LV-PUR131, White

Levoit is a popular name in home appliances. In their air purifier range, they cater to the low-mid range market. The LV-PUR131 doesn’t stray from the path. Covering an area of up to 322 sq.ft. this unit is useful for when the odor from weed from a neighboring house is affecting you. It may not be the prettiest looking machine but at under $200 it’ll do the job you want it to. 

You get to choose from three fan speeds that circulate the air through its three filters. The carbon filter in the Leviot is packed with over 20,000 columnar activated carbon to adsorb and deodorize the smell of weed creeping in. There is no ionizer or UV in this unit so, on the one hand, it’s 100% ozone free, on the other, it doesn’t have that extra feature to help with odor.

The interface is easy to navigate, with every button labeled and an LED display in the middle which changes color to indicate the quality of the air. The smart sensors adjust fan speed keeping energy consumption down and there’s a handy timer if you know when the smell of weed is going to hit.

What we love: 

  • The honeycomb activated carbon filter 
  • Ideal for apartments

We don’t like this as much:

6. TruSens Z-3000

TruSens Air Purifier | 360 HEPA Filtration with Dupont Filter | UV-C Light | Dual Airflow for Full Coverage (Large)

TruSens units have a different design approach to most of the purifiers on the market. The tower-like cylinder almost resembles a building from the Hong Kong skyline. The top of the unit uses dual airflow to distribute the clean air evenly throughout the room. This flagship larger model covers up to 750 sq.ft and slots nicely into the mid-range. 

The Z-3000 houses a pre-filter, True HEPA filter, activated carbon filter, and a UV-C light filter which helps with the odor-causing bacteria we mentioned before and because of its circular design, captures odors from 360 degrees. Combining the four-stage filter with its turbo fifth speed, the TruSens will make light work of eliminating your weed smoke smell.

For the feature seekers out there, the Z-3000 comes with a SensorPod. This little box can be placed across the room to measure pollutants producing a more accurate air quality reading in real-time. It sends that information to the unit to give you a digital reading. There’s also a timer, night mode, and will tell you when the filter needs changing.

What we love: 

  • Has a carry handle
  • 5 fan speeds

We don’t like this as much:

  • Is quite loud
TruSens Air Purifier | 360 HEPA Filtration with Dupont Filter | UV-C Light | Dual Airflow for Full Coverage (Large)
  • SMARTER SENSING: Most traditional purifiers don't know the air quality in the room. TruSens does, and reacts. Our remote SensorPod will actively monitor the air quality of the room and take action. Placed across the room, SensorPod communicates back to the TruSens purifier so it can automatically adjust its fan speed. This way, you can be certain the entire room is benefiting from cleaner air.
  • DUAL AIRFLOW: PureDirect proprietary technology splits clean air into two air streams, delivering purified air more comfortably and efficiently throughout the room. The result of rigorous testing has proven that bi-directional airflow delivers purified air more effectively throughout a room, and in some cases, has been proven to be up to 24% more efficient.
  • DETAILED LED DISPLAY: Air conditions in your home can change rapidly. Information is power and TruSens purifiers give you the power to manage your home’s air quality. The color coded LED display will provide the peace of mind from knowing that TruSens is taking action on your behalf. Our air purifiers were designed with a simple touch controls for all the functions that matter most, including fan speeds, auto-timer, UV mode and filter replacement indicators.

Frequently Asked Questions

Do air purifiers eliminate the smell of weed?

The smallest particles produced by weed smoke are between 2.5 and 0.03 microns. These microns are captured by air purifiers with True HEPA filters. Compared to cigarette smoke, weed smoke is lighter but much more potent, sticking to clothes and furniture. The activated carbon filters work by absorbing the odor that comes from cannabis. As weed is often smoked with others, an air purifier with a strong fan and high carbon filter count is best.

Are air purifiers safe to use in the home?

Air purifiers are perfectly safe in the home as long as you use them correctly and do your research. Some purifiers do emit toxins known as Ozone. Too much of this can be harmful. Be careful of units that describe themselves as “energized oxygen” or “superoxygen”. When choosing an air purifier for your home, look for certification from a local governing body e.g. CARB (California Air Resources Board).

Around 12% of Americans now smoke weed in their homes. It’s become a pastime for hanging out and socializing. Having the right air purifier in the home will help remove the odors associated. On the flip side, if your home is affected by the smell of weed from the neighbor or housemate, a good unit will save your possessions from that potent odor.

Which air purifier is best for you?

  • Budget/smaller rooms –  We would go for the Blueair Blue Pure 411. It’s simple to use, very effective in smaller rooms, and costs around $100.
  • Mid-range – Our choice for a mid-range unit would be the TruSens Z-3000. It has great filters like the SensorPod, and looks stylish.
  • Larger rooms – It’s a close race between the RabbitAir and the Alen but the BreatheSmart Classic wins for its superior CADR ratings and the area it will cover.
