We took a look at some of the more popular models on the market to find air purifiers that match up to their claims. We evaluated the effectiveness of these different models on various smoke types to find the best one to match your particular needs, including portable air purifier options for use in multiple rooms.

Read on to find the best air purifier for smoke that will be best for your home or office.

Best Air Purifier for Cigarette Smoke Removal

Best Air Purifier for Cigarette Smoke Removal

The Honeywell HPA300 is an excellent option for mid-sized rooms since it has a coverage area of around 465 square feet. It has a CADR of 300, meaning it can cycle the air in 465 sq. ft. area five times per hour.

The Honeywell has both an activated carbon pre-filter and a second-state HEPA filter to deliver excellent results. The carbon filter will remove most odors and volatile organic compounds (VOCs), while the HEPA filter removes fine particles like tar and carcinogens associated with smoking making this one of the best air purifiers for smoke.

An important factor to consider when choosing an air purifier is its ease of use. The HPA300 has an intuitive system with a filter-change indicator that will let you know when it’s time to replace a particular filter.

According to the manufacturer, you can expect to replace the carbon filter every three months and the HEPA filter once a year. However, it’s important to note that this timeframe is a guideline only, and you may need to replace your filters sooner or later, depending on the amount of smoke in the air.


  • High CADR rate
  • Easily replaceable filters with filter-change indicator
  • Sleek, modern design


  • Some people find the touch controls fiddly and prone to failure

Best Portable Air Purifier for Cigarette Smoke

Best Portable Air Purifier for Cigarette Smoke

The Fellowes AeraMax 90 weighs just nine pounds, making it ideal for moving around from room to room. It has a small base and minimal control panel that helps it blend into the background where it efficiently does its job of purifying the air.

The AeraMax 90 uses a four-part air cleaning system to remove smoke particles, odors, and any other airborne pollutants and pathogens. The system includes:

  • Activated carbon filter: The carbon filter acts as a pre-filter, catching larger particles and neutralizing most unpleasant odors.
  • True HEPA filter: The main workhorse of the air purifier, the true HEPA filter, stops any particles under 0.3 µm from passing through. It’s enough to stop most allergens, viruses, bacteria, mold spores, mites, and smoke particles.
  • Antimicrobial treatment: As an extra layer of defense, the HEPA filter has an antimicrobial coating that prevents the growth of mold or bacteria in the filter, extending its lifespan and preventing strange odors from coming from the purifier.
  • PlasmaTrue ionizer: The final filter is an ionizer that removes all the tiny particles that slip past the HEPA filter. These particles are light enough to get ionized and stuck to the plates of the filter. If you’re concerned about the health effects of ionizing filters, you can turn this option off. However, the filter does comply with the standards of both the CARB and the Asthma and Allergy Foundation of America for ozone emissions.

Since it’s a portable air purifier, the AeraMax 90 has relatively small room coverage of 100 sq. ft. and a low CDR of 75 for smoke. It can exchange air three times an hour if used within its capacity making it one of the best air purifiers for smoke.

One appealing feature of the AeraMax is the Smart Sensor function, which detects pollutants and automatically turns itself on. It will also adjust fan speed depending on the concentration of contaminants, which will save energy and prolong your filter’s lifespan.


  • Affordable and portable
  • Excellent True HEPA filter with an extended lifespan
  • Three-year warranty

Common Types of Smoke

All kinds of smoke, including cigarette, weed, and wildfire smoke, contain carcinogens and other compounds that are harmful to human health. Even mild exposure to smoke can result in lung and eye irritation, and unfortunately, the smell of smoke also can linger for days afterward.

Air purifiers are an excellent way of getting rid of smoke, but it’s also important to note that various types of smoke have different characteristics. If you’re predominantly worried about wildfire smoke, you may want a different air purifier to someone who wants to get rid of cigarette smoke.

Tobacco Smoke

Tobacco smoke has a distinct aroma that permeates into every part of your home, from your clothes and hair to your furniture and carpet. Second-hand smoke is as dangerous to your family’s health as first-hand smoke is to your health, making air purifiers an excellent option for families with smokers.

An added benefit of installing an air purifier is that it reduces tar build-up. Houses with heavy smokers tend to accumulate tar on the walls and furniture, which causes a yellow discoloration that’s difficult to remove. 

If you’re looking for an air purifier to handle tobacco smoke, you need one that can remove the small, harmful compounds, tar, and odors associated with this type of smoke.

Weed Smoke

Now that marijuana is legal in most states, many people are enjoying its effects at home. However, while some people appreciate the pungent odor of weed, many people dislike it intensely. 

Weed smoke produces less tar than tobacco smoke but will still produce some harmful compounds as part of the burning process.

Ideally, to remove weed smoke, you want an air purifier that can handle the strong odor associated with the herb.

Wildfire Smoke

If you live in an area with regular wildfires, you know the effect that both the smoke and particulates can have on your health. Wildfires generate many carbon particles that are detrimental to your health and produce a strong odor that’s difficult to remove. 

When looking for an air purifier to deal with wildfire smoke, look for one that has a good particulate filter, as the greatest risk from wildfire smoke comes from these carbon particles. 

Types of Filters

There are three different general types of filters that each remove a different component from the air: mechanical filters remove solid particles, chemical filters remove gases, like smoke odors, and biological filters remove biological compounds, such as bacteria and viruses. 

Some filters remove several different compounds at the same time, while others specialize in removing one. Understanding what different filters do will help you choose the right one to combat smoke in your home. 


High-Efficiency Particular Arresting, or HEPA, filters are some of the most common filters on the market. This ultra-fine glass fiber filter traps solid particles as well as bacteria and viruses that are too large to pass through the holes in the filter.

Beware of the many HEPA-like filters that don’t have the same filtration level that true HEPA filters do. If you want the best protection and air purifying capacity, stick to certified filters that block 99% of 0.3 µm particles. 

Activated Carbon

Activated carbon is the most common filter used to remove odors. The filter contains activated carbon that can bind to gases and render them inactive. Unfortunately, once every molecule of active carbon has absorbed a gas, the filter will start losing effectiveness, and you’ll need to replace it.


UV purifiers are excellent at destroying biological contaminants such as bacteria and viruses. Isolation wards in hospitals use UV purifiers along with HEPA filters to keep the air inside sterile. 

UV purifiers work by damaging the DNA of the living organism so that it can’t reproduce. While prolonged exposure to UV is also harmful to humans, UV purifiers keep the rays in a filtration box to limit human exposure. 


Ionic filters work on the principles of polarity. The ionic plates generate a negative charge, which attracts positively charged molecules in the air, removing them and sticking them to the negatively charged plates.

Ionic filters are effective at chemical filtration and some mechanical filtration, but often need a combination with some other filter to be effective.


Photocatalytic electrochemical oxidation, or PECO, filters destroy particles by oxidizing them with a reaction powered by light energy. Since PECO filters are still relatively new, you can expect to pay a hefty premium for the privilege of using one. 

Other Considerations When Choosing The Best Air Purifier for Smoke

It’s always a good idea to do your research before buying an air purifier. With so many options on the market, you need to have a clear understanding of your needs before you start shopping around. There are a number of factors to consider when choosing the best air purifier for smoke. 

Purification Area

Different air purifiers have different power levels, which impacts the size of the area they can effectively purify. Most manufacturers will specify the area for which the air purifier is suitable, and it’s a good idea to keep slightly under the maximum area for the best performance.

Also, consider the CADR, or clean air delivery rate, which measures how efficiently and quickly the purifier handles a certain volume of air. A lower CADR indicates an air purifier that will take longer to purify a volume of air than a machine with a higher CADR. 

If you smoke a lot, the best air purifier for smoke will likely be a unit with a higher CADR and a larger maximum area to speed up the purification process.

Filter Life

Different filters have different lifespans influenced by how much use they get. A HEPA filter can last up to five years with light use or get clogged up within two years with heavy use. 

Carbon filters are notorious for having relatively short lifespans, so be sure that you can afford to replace a filter regularly to ensure optimal performance. 

Some filters will need less maintenance than others. UV filters need a replacement bulb every couple of years, while ionic filters need a gentle clean according to manufacturer’s instructions. 


Whether or not you need a portable air purifier will depend on how you plan to use the machine. Some air purifiers are very large and can weigh up to 20 pounds. Most people will place these purifiers in a room without the intention of moving them. In this case, the best air purifier for smoke may be the one that is easiest to move around.

There are also more portable models that are smaller, but they are less effective at cleaning a large area than their bigger counterparts. However, if you move around the house a lot, a smaller portable air purifier may be the right choice for you.

Unlike commercial air purifiers, most residential air purifiers don’t need professional installation. Just place it where you need it, plug it in, and enjoy the cleaner air. 

Noise Level

Most air purifiers have a pump to move air through the filter. Some are quieter than others, and what you feel is ‘too much’ will depend on your personal preference. You may be fine with a loud unit in the kitchen or lounge, but it won’t be suitable for your bedroom at night.

Typically, most air purifiers will have a decibel rating of between 17 to 56 dB(A), which is below ordinary conversation levels. If possible, try out several purifiers in a small area to see how well you tolerate the noise they make. 

Energy Efficiency

With energy prices on the rise, it’s important to consider air purifiers that are energy-efficient. Look for Energy STAR compliant models, as they’ll use significantly less power than non-compliant models.

Higher-capacity models will use more energy than lower-capacity models, and certain types of filters will consume more power. Check the wattage on the various models to find one that best meets your needs. 


Warranties are a good indicator of how much manufacturers trust their products. Shorter warranties may not be an indicator of low-quality products, but if you have to choose between two models, choose the one with the longer warranty.

We also strongly recommend reading the fine print of a manufacturer’s warranty. A five-year warranty sounds great, but it may only cover certain parts under certain conditions. Make sure you fully understand a warranty to avoid unpleasant surprises in the future.


Your price range should factor in your budget and how often you plan to use your unit. Higher-quality units will process air faster but cost more money, which may be a waste if you intend to get rid of some marijuana smoke only once a month. 

Many people also make the mistake of buying a significantly higher capacity air purifier than they need, thinking it will work faster. Remember that area and CADR are two different factors, and ideally, you want an air purifier that has a similar capacity to the room you’ll use it in. The best air purifier for smoke does not always need to be the most expensive option.
