List of Best Air Purifier for Weed

Rabbit Air BioGS 2.0 Ultra Quiet HEPA Air Purifier


  • Activated Carbon filters
  • 4 stages of purification
  • Quiet motor
  • Energy Star Certified
  • 5-year warranty

To start with, this is easily the best-rated air purifier on the market. It is highly effective and extremely easy to set up.

This air filter has a four-stage filtration system that works very well in terms of combating smaller particles that could adversely affect your health such as pet hair, dust, and fungi whilst filtering out larger ones such as viruses, allergens, and mites by way of its pre-filter.

Its HEPA filter filters out the smallest particles which can be as small as 0.03 microns permitting you to breathe freely again knowing that various pollutants that can often worsen airborne illnesses, as well as form mold, are neutralized.

Once these pollutants are filtered they are trapped through the third stage after being treated by two different kinds of filters namely activated charcoal and ion generators.

The RabbitAir BioGS 2.0 Turbo Quiet Air Purifier stays hard at work all day, keeping your indoor air clean and healthy!

It monitors impurities continuously to keep the air clean and switches to the high-speed mode when it detects smoke or other substances that could cause you harm.

When it’s running in Auto Mode, an LED light runs across the display bar so you’ll know when your purifier is active.

Alen BreatheSmart is a compact and multi-functional air purifier that can handle large rooms up to 1,100 square feet.

There’s HEPA-pure which is the standard functioning HEPA (high energy particulate arresting) filter – capable of filtering 99% of pollutants down to 0.03 microns in size!

Or the second stage HEPAs can simply be adjusted manually or via the remote control while stage three uses electrostatic technology to capture particles.

  • 3 fan speed

Levoit’s LV-PUR131 earns a place among our best air purifiers because of its great deal of flexibility. Even though it can cater to heavy smells and smoke from common home appliances such as weed, litter, and candles (among others), the LV-PUR131 doesn’t overwhelm its users with a lot of confusing buttons and settings.

In fact, many users like its simple interface – for instance, the smart auto mode. This is a mode that can be easily turned on and then forgotten about.

It changes itself regularly from clean to sleep depending on what time it is. It also offers easy maintenance with the pre-filter needing only minimal upkeep to stay odorless and dust-free.

This air purifier uses a sensor to check and indicate the quality of the air in your home, then automatically suggests the best fan speed.

Sleep mode is also available. It puts the unit into its lowest setting, drastically reducing fan noise, and pairs with an auto-shutoff timer. Product design is pleasant enough and it has lasting build quality.

These filters should be changed every six months, but they’re also cheaper than their competitors’ replacement filters.

RabbitAir MinusA2 Ultra Quiet HEPA Air Purifier

  • HEPA filters
  • Corded electric source

  • 19.4 Pounds weight
  • 5 Year Warranty

The Rabbit Air MinusA2 is stylish and includes customizable panels that make it look like a framed painting. It can be mounted on the wall or as a stand-alone unit.

It’s not too big so its size doesn’t take up too much room, unlike other air purifiers with similar features. With six different filtration stages and an SCGI mode for nighttime use, the design of this air purifier excels in purifying floors and carpets effectively while reducing allergens, dust mites, and bacteria – potentially helping to ease symptoms related to asthma and allergies.

The third stage is the BioGS True HEPA filter, which removes 99.97% of impurities up to 0.03 microns while preserving clean airflow and minimizing the cooling loss range.

The fourth stage is the customized filter. Here, you have a choice between the Germ Defense filter and the Toxin Absorber filter.

The Germ Defense trap and prevents the growth of bacteria, mold spores, and viruses while protecting individuals with compromised immune systems from potential health concerns they can experience that could arise from within their very own home environment in its early stages.

On the other hand, the Toxin Absorber trap VOCs (gases from certain liquids and solids), reducing their effect on users by limiting exposure to airborne toxins that might otherwise carry harmful health effects for those who are vulnerable to them in one way or another.

Other filter options include pet allergies (for pet dander), odor removal (to get rid of cooking smells, household chemicals, mildew, and smoke), granular activated carbon for odors, negative ions (for better odor absorption), and five fan speeds ranging from silent to turbo.

Germ Guardian True HEPA Filter Air Purifier


  • True HEPA air filter
  • Trap 99.9% of germs
  • Remove 0.3-micron allergens
  • Activated charcoal filter 
  • Quiet operation

This is the cheapest of the lot and one of the most basic purifiers featured on our list. Thankfully it still does everything that a good air purifier should do – clean the air while filtering smoke and odors, and it provides high airflow at an impressive CFM range.

The purifier comes with a 2-year limited warranty against defects and workmanship. The filtration process consists of a pre-filter for hair and pet dander along with other impurities that can’t be removed using a fast rate airflow (which would cause issues to your health).

We would recommend this one for anyone who needs something very portable – perhaps someone who travels frequently or has pets that shed a lot.

The True HEPA filter removes all other contaminants including particles as small as 0.03 microns with a 99% accuracy.

It has a 55-watt UV-C lightbulb that also eliminates bacteria and mold spores, making it ideal for smaller rooms like bedrooms and offices though it comes at the cost of slightly more noise than its competitors on the market.

This 3-speed fan is still considered louder than many modern devices and makes 40 decibels at its lowest – tough to get through if you want to just chill out or want to sleep and the device remains far too noisy compared to its rivals but despite these weak points, you can’t go wrong with this!

What We Like

  • Noise-free
  • Sleep well
  • Lightweight
  • Works with titanium oxide
  • Low cost

What We Don’t

  • Low quality

Hathaspace True HEPA Air Purifier


  • Sleek design
  • HEPA filters
  • Customer support
  • Simple controls

Many users talk about how well Hathaspace True HEPA Air purifier worked to clean the air, especially from any lingering smoke.

Many new buyers have indicated their appreciation for how often they should replace the filters. In addition, many people have expressed their immense satisfaction with how quickly the units make their homes smell fresh again after a party.

The first thing that stands out to us is that there are five different functions this purifier offers: removing harmful gases and VOCs, as well as absorbing weed smoke and other odors.

These three filter elements (if available) should be present in the following order: pre-filter, true HEPA filter, and ionizer.

It is important to note that these are not necessarily in that order for all systems as manufacturers sometimes have special air filters that come before the HEPA filter. (i.e., an Optional UV lamp may precede a true HEPA filter).

Ionizers utilize negatively charged particles or ions to neutralize positively charged airborne particles by either attaching themselves to them or repelling them back down to earth without ever needing to touch them – this is a unique feature of the particulate air purifier.

This process also has some ionic or antioxidant benefits due to its distinctive effect on airborne molecules containing oxygen, like ozone and volatile organic compounds, which we can subsequently breathe more easily.

The activated carbon will also get rid of the smell of cannabis lingering in the air. This system is effective for about 10 to 12 months before having to be replaced.

In addition to binding toxins from smoke from marijuana or weed, this unit features a smart sensor on the display that indicates the quality of air with real-time color (blue for pristine, orange for average quality, and red for the poor quality).

The Fellowes AeraMax 300 is a great choice for anyone looking to purify the air in mid-range rooms from 300-600 sq ft.

Its patented “Aeraconditioning” technology comes with a 4-stage filtration system including activated carbon and antimicrobial treatment (True HEPA) which keeps your machine clean of any impurities or developing bacteria, extending its operation and performance over time.

We most often go sniffing through ionizer air purifiers. Because they can sometimes be harmful to the body, we look for organizations that have created standards of safety that go beyond industry requirements like HET (High-Efficiency Technology).

The AeraMax 300 includes a smart sensor that reduces allergens such as pet dander and dust mites by more than 99%.

Furthermore, this unit continually adjusts automatically to your given space. Now, it does not indicate the quality of your air but it will give you consistent results in order to maintain a healthy home.

Buyers Guide of Best Air Purifier for Smoking Weed

Filter Types

The largest particles in weed smoke are between 2.5 and 0.03 microns in size. HEPA air filters can remove, 97% of all contaminants, making it the most effective method to clean a grow room environment.

However, these fine fibers can be clogged by larger foreign bodies, like dust or pet dander. When using a HEPA filter with a pre-filter together you can minimize the risk of clogging in addition to getting healthier plants and a lower electric bill because you aren’t needing to use your blower as much.

Take the time to check and vacuum your pre-filter on a regular basis! This will help you remove larger bits of visible dirt, which may end up in your machine.

If this is too difficult, you can purchase reusable or washable filter papers! These are a great option because they make all of your removal processes much easier and more efficient.

Since larger filter papers take care of large amounts of dirt, they will last longer than a small, poorly made paper. This means that you won’t need to change your paper as often.

Strong Airflow

Compared to cigarettes or cigars, weed smoke is light. It also contains a significant amount of odor in comparison to other kinds of smoke and therefore requires more powerful fans that can be set up in order to circulate the smoke throughout a room for the purposes of purification.

Because smokers often host communal events there will likely be many people smoking simultaneously, causing the need for a fan that can be adjusted for those specific instances.

A more cost-effective solution may simply consist of using a strong air conditioning system, window fan, or ceiling fan that circulates air around a room through several vents so as to produce an overall higher quantity of circulated air within a space (i.e while still allowing you to control its location as well as speed).

The higher the level of quality your purifier is designed with, the less likely you are to detect any additional odors in areas where smoking takes place afterward.

Activated Carbon

When combined with a HEPA filter, activated carbon is the right choice for air purification. Activated carbon is particularly useful when it comes to removing combustible fumes and volatile organic compounds (VOCs).

This type of air treatment solution has the ability to adsorb contaminants’ smells – to absorb them. No, that’s not a typo – adsorption is actually a type of absorption process used specifically with gases and fine liquids.

Voice Control with Alexa

The air purifier needs to be adjusted sometimes and having a remote control will make this difficult because you’d have to walk across the room every time.

To solve this problem, you can connect Google Assistant on your phone with the air cleaner so that you can change settings as you please while standing comfortably in one place.

CADR Rating

​The term is used by manufacturers for smoke removal when in reference to “Clean Air Delivery Rate”. Essentially the CADR rating is an air quality statistic that refers to how much air can be moved per minute.

An air purifier with a high fan speed rating also has higher CADR ratings e.g. an air purifier fan’s capable of moving 450 cubic feet per minute (cfm)is deemed better than one that achieves only 300 cfm or less.

FAQs Related to Best Air Purifier for Smoking Weed

Cannabis smoke consists of two forms of pollutants: particulates and volatile organic compounds (VOCs). The particulates found in weed smoke can be either solid or liquid, with some of these particles being microscopic.

Since marijuana tends to have a higher water content than tobacco, there are more liquid particles in cannabis smoke that can be inhaled deep into the lungs. These tiny particles could potentially build up over time and cause lung damage according to health experts at the American Lung Association.

In order to protect your lungs and home from the harmful effects of smoke, you need air purifiers that are able to remove smoke particles from the air and neutralize their odors as quickly as possible in order for them not to stick around on surfaces.

A great air purifier for a cigarette, cigar, and weed smoke consists of a device that’s small and fully portable. This kind of appliance should be able to provide a great deal of convenience to you so that whenever you go out for a walk or join friends for a long, drawn-out smoking session, you’re also taking protection with you wherever you go because if an odor from one of these undesirable elements is trapped in your clothes before or after being trapped in an area where it shouldn’t be, it could result in some pretty unattractive situations.


Smoking weed in unfiltered air can be harmful to your health. However, you don’t want to make it hard for yourself by not smoking at home. That’s why an air purifier is the best way to go.

The best air purifier for smoking weed can make a huge difference to the quality of air in your home. If you are spending a lot of time at home you should make sure that you have the right air purifier to help you breathe cleaner air even if you are a smoker.
