Best Air Purifiers for Smoke in 2023: Buying Guide

Cigarette smoke. From a non-smoker’s point of view, the pungent smell of cigarette smoke is automatically detectable. If you live with someone who smokes, you undoubtedly get tired of arguing about his or her habit and how it makes the house malodorous.

On the other hand, if you are a smoker, you don’t want your entire house to smell like a stale cigarette, but you don’t want to sweat or freeze to death just to go outside for a cigarette. Even if nobody in your house smokes, you may invite smokers over on occasion, and you don’t want to gripe at them for smoking indoors.

What’s the solution to eliminating the smell of cigarette or cigar smoke? Sure, you can designate a single room just for smoking or breathe the smoke out of an open window, but the smell will still linger. A better solution to living in smoke-free harmony is an air purifier.

This miraculous machine draws in dirty, contaminated air through large inlets. Then, it circulates the air through a series of filters and particle-destroying mechanisms before it releases the now-clean air back into the room. An air purifier can destroy all types of smoke-causing odors, including those from cigarettes, cigars, fireplaces and stoves.

Recommended Budget Air Purifiers in 2023

Pure Enrichment PureZone 3-in-1 True HEPA Air Purifier

Pure Enrichment’s PureZone air purifier is ideal for floor or table placement in small living rooms or kitchens and average-size bedrooms of up to 200 square feet.

Pure Enrichment PureZone 3-in-1 True HEPA Air Purifier

This white purifier weighs 8.4 pounds and measures 12.1 inches tall by 10.8 wide, so if you go the tabletop top route, make sure it’s large and sturdy enough to accommodate the purifier. As far as the warranty, Pure Enrichment covers the machine for 5 years, which is much longer than what many other manufacturers offer.

The top-located control panel is equipped with clearly marked touch buttons, one of which is for resetting the filter indicator. There are two recessed handles on the side that allow you to pull off the front panel for quick bi-yearly filter changes. Behind this panel, you’ll find a pre-filter that collects dust and hair as well as a true HEPA filter and activated carbon filter for smoke absorption.

Additionally, the panel lets you reach the UV-C light bulb. However, with a 20,000-hour lifespan, you’d only have to change it once every two years even if you used the machine 24 hours a day, 7 days a week. Since the UV-C lamp emits 254-nanometer wavelengths, it’s capable of killing all types of germs that circulate through the purifier.

With this air purifier, you can choose from among three fan speeds, which range in decibel output from 30 to 50. There is also a 2, 4 and 8-hour timer option. Plus, there is a sleep mode that runs the fan at the lowest speed and turns off all indicator lights. AHAM gave this purifier a CADR of 80 cubic feet per minute, so it can definitely handle smoke-particle removal.

With a lifespan of 1 year, even the UV-C bulb lasts for a long time. To boost its germ-killing effects, the UV-C light is kicked into gear by a plate of titanium dioxide, which is an excellent photocatalyst.

Common Features to Look for in Air Purifiers

Without a doubt, the chemicals found in smoke contain numerous airborne toxins. Besides the obvious health dangers, you certainly don’t want your home to smell like an ashtray, burnt wood or overcooked food.

Thankfully, there are air purification machines that can take away these harmful particles and the smells that come with them, leaving the air clean and fresh. While their room coverage, size and other facets may differ, most high-quality air purifiers share many similar features.

HEPA Filter & Optional Purification Technologies

Whether it’s a true HEPA filter or HEPA-type filter, any decent air purifier is going to have some version of a HEPA filter. Along with the fan, this filter is responsible for capturing allergens.

For the best results, make sure the model you choose has a true HEPA filter because this type of filter is able to trap the most .03-micron particles.

Although the HEPA filter and fan do a lot of the work, some manufacturers throw in other purification technologies. The most popular ones include a germicidal UV-C light, an ozone generator and a negative ion producer. While not essential, if you are someone who likes to have it all, any one of these features will only serve to enhance the air purifier’s efficiency.

Multi-Speed Fan & Timers

Every air purifier must have a fan in order to circulate incoming air through the filtration system. However, some of the economic models run on only one fan speed. While a single-speed fan is acceptable for personal purifiers, you’ll want an air purifier that lets you tailor the fan speed to meet the room’s square footage and the air’s level of cleanliness if you’re going for whole-room coverage.

Sure, there are times when you may want to run your air purifier non-stop. There are also times when you only need to use it for a few hours, such during and after a cigarette or while you’re cooking. These instances are when a built-in timer comes in handy.

Virtually all air purifiers with a timer let you set it for one of several time frames, ranging from 1 hour to 12 hours.

Nightlight and Sleep Mode

Air purifiers are a health-and-wellness product. Therefore, many manufacturers integrate a gentle nightlight into their purifiers to facilitate restful sleep; the light is usually blue, but it can be multi-colored. If you opt for one with a nightlight, make sure it gives you the option of turning it off or changing the brightness.

Sleep mode is not necessary, but it’s a nice convenience feature to have, especially if you’re a sensitive sleeper. On most models, the fan automatically drops down to its lowest speed when in sleep mode. Some air purifiers go one step further and turn off all lights, including nightlights and indicator lights.

Top-Rated Air Purifiers For Smoke

Buying Guide

Why buy an air purifier if it’s too difficult to use or expensive to maintain? Even worse, if it’s not sized right for the room, the purifier won’t do you much good in eliminating nasty odors. To rid an enclosed area of smoke smells, there are certain features that are important.

Control Panel

The control panel is perhaps one of the most important usability features – It’s where you can select and change every function on the air purifier, so you want to make sure it’s easy to use. A dial knob is always super simple. However, if you prefer the look and feel of a flat panel, make sure each button is clearly labeled with a word or logical picture.

Pre-Filter and Carbon Filter

A HEPA filter alone is not going to make smoke smells go away. The purifier also needs an activated carbon filter to capture those odors. In addition, the filtration system should also include a pre-filter that keeps dust, hair and other large particles from reaching the HEPA filter, so the machine runs as smoothly as possible.

Filter Maintenance

No filter lasts forever, but you certainly don’t want to spend money every month on a new filter. At bare minimum, make sure the purifier you choose has a filter with a 3-month lifespan. To extend the life of the HEPA filter, read the manufacturer’s notes about filter maintenance – there are some pre-filters you can vacuum to make them last longer and maximize the purifier’s efficiency.


Also, pay attention to the measurements of the purifier. If you plan to put the air purifier on your nightstand or desk, you’ll need a lightweight model with a slim profile. However, if you need a model that can purify the air in a large room, that purifier is going to be bigger than the tabletop variety, and it most likely must be placed on the floor.

Square Footage

How big is the room where you will use the air purifier the most? If you choose a purifier that is too big for the room’s size, you’ll waste needless energy when running it. On the other hand, if the purifier is too small, it won’t be able to circulate all the air in the room, making it run harder and work ineffectively.


In relation to the square feet of the room, there is the machine’s clean air delivery rate. This number tells you how much air can pass through the purifier per minute. Your chosen air purifier should have a CADR rating that corresponds to the room’s size.

You want to go for the highest number possible.


If energy efficiency is important to you, look at how many watts the air purifier consumes. This information should be listed on the box, in the manual or in the seller’s description. Since air purifiers are appliances, those that don’t drain a lot of electricity are typically Energy Star certified and will proudly display that certification logo.

Particle Sensor

Advanced air purifiers contain a particle sensor. This sensor measures the number of particles in the surrounding air, and it will show the results on the control panel’s digital display.

Purifiers that have an auto mode will change the fan speed per the number of airborne particles when in this mode to make the purifier runs efficiently and cleans the air quickly.

Best Air Purifiers For Smoke, Odors


Exposure to wildfire smoke has been linked to increased risk of cardiovascular and respiratory health effects, including allergies and asthma.


How Does Smoke Cause Odors?

When someone lights up a cigarette, over 7,000 chemicals are released into the air through secondhand smoke via a twofold process.

First, there is the smoke that comes from the lit end of a cigarette, which is called sidestream smoke. Then, there is the smoke known as mainstream smoke that comes from the exhaled smoke.

Sidestream and mainstream smoke contain particles of ash, burned tobacco and an array of chemicals and carcinogens. Some of these chemicals are deliberately added by cigarette manufacturers while others are byproducts of combustion.

These particles not only enter the bloodstream and respiratory system but also attach to books, fabric and other porous surfaces. Plus, the tar resin from cigarettes becomes sticky as it cools, eventually leading to telltale yellowed walls and facilitating the ability of ash and smoke to stick to surfaces.

Did you Know

That your neighbor’s secondhand smoke can seep into your house?

What are Volatile Organic Compounds?

Volatile organic compounds are chemical gases released by tobacco smoke, air fresheners, burning wood and other items. In cigarettes, some common VOCs are carcinogenic particles like benzene and formaldehyde.

VOCs can lead to acute ailments such as eye irritation, headaches and fatigue. This health problem is sometimes called sick building syndrome. Luckily, many air purifiers can reduce the concentration of VOCs in the air.

What Does CADR Mean?

When shopping for air purifiers that can get rid of smoke odors, you’ll see the acronym CADR a lot. In order to determine the effectiveness of an air purifier, the Association of American Home Appliance Manufacturers measures how much clean air is emitted from an air purifier while on the highest speed setting.

This measurement is given in cubic feet per minute, and it’s known as an air purifier’s clean air delivery rate.

To give consumers a full picture of an air purifier’s capabilities, the AAHAM puts a CADR score on the machine’s ability to eliminate particles from 0.09 microns to 11 microns; therefore, every air purifying machine has a CADR number for smoke, dust and pollen. For tobacco smoke, the CADR number ranges from 10 to 450.

Best Air Purifiers for Smoke

What Are the Odor-Reducing Components of an Air Purifier?

For an air purifier to get rid of the odor caused by cigarette smoke, it must do more than trap dust and dander, so a standard filter won’t work for reducing smoke odors. It also needs to address the smaller airborne particles that cause odors. Therefore, only an air purifier with HEPA and carbon filtration will get the job done.

What are HEPA Filters in an Air Purifier?

A true HEPA, or high-efficiency particulate air, filter is a type of filter that can trap almost 99.97 percent of microscopic particles such as bacteria, viruses, fungi, allergens and irritants as small as 0.03 microns.

However, just because a purifier says it has a HEPA filter doesn’t mean the filter is a true HEPA filter. While some HEPA-type filters resemble true HEPA filters, HEPA-types consist of looser fibers, so they capture the same amount and size of particles.

Instead, HEPA-type filters can only trap 25 percent to 99 percent of airborne contaminants. Often, these filters max out at 2.0 microns, making them excellent at collecting dust but ineffective at eliminating smoke particles. Sometimes, air purifiers are equipped with a pre-filter, which blocks larger particles to optimize the HEPA filter and lengthen its lifespan.

What are Carbon Filters in an Air Purifier?

Often, manufacturers include a carbon filter to expand the air purifier’s capabilities. Activated charcoal/carbon filters are extremely porous, and they are highly adept at trapping gas particles such as VOCs through a chemical reaction caused adsorption. To produce the best purification results, a carbon filter is usually paired with a HEPA filter.

Are There Other Air Purification Technologies Beside HEPA and Carbon Filters?

Although the process of drawing in dirty air and releasing clean air is at the core of any air purifier, that’s where the general similarities between air purifiers stop.

Some models are built with one or a combination of technologies, all of which are designed to clean air in different ways. Apart from HEPA and carbon filters, there are three popular technologies used by air purifier manufacturers.

What are Negative Ions in an Air Purifier?

Also known as anions, negative ions are particles with a negative charge. Typically, an air purifier creates negative ions by directing voltage to integrated needles. Then, the purifier releases these anions into the surrounding air where they attach to smoke particles and other allergens.

In turn, the newly formed particle is large enough to be easily captured by the air purifier. On its own, an anion generator can’t remove smoke odors. However, when anion generation is combined with the right filtration system, the purifier becomes more efficient at odor removal.

What is Ozone in an Air Purifier?

Like negative ions, some purifiers create ozone on purpose, which is made from three molecules of oxygen. With the help of an electrostatic plate, a purification machine takes in oxygen from the surrounding air and electrically charges it.

When this happens, the oxygen molecules separate and scatter, turning into O3, or ozone. This is similar to what occurs when lightning strikes. Once it has made 03, the machine releases the O3 into the room’s air.

From there, the ozone sticks to odor-causing particles. However, instead of waiting for the purifier to draw in the ozone-combined particles, the ozone destroys these particles at the molecular level. This process not only gets rid of foul odors but also allows O3 to turn back to a single molecule of oxygen.

Again, for an ozone-producing purifier to be effective at getting rid of smoke and its accompanying smell, it should utilize other technologies along with ozone generation. To be safe, it’s important to ventilate the room when an air purifier is releasing ozone to prevent lung damage.

What is Ultraviolet Light in an Air Purifier?

Another method used by manufacturers to sanitize indoor air is ultraviolet light. Inside of some air purifiers, there is a bulb that contains artificially-made UV-C light. In order to harness the power of UV-C light, an air purifier pulls in dirty air, so there is no risk of ultraviolet exposure to users. First, this air goes through a HEPA filter. Then, the filtered air reaches a compartment that holds the UV-C light bulb.

At this point, the germicidal UV-C light destroys the DNA of all types of microorganisms. In some cases, the air passes through a post-filter before it’s released back into the room. Although UV-C light is great for killing bacteria, mold and viruses, it’s not ideal for eliminating cigarette smoke.

However, it keeps an air purifier’s filters from becoming clogged, so the filters and other technologies can work more efficiently at drawing in air and destroying smoke odors.

About the author

Hi I’m Alex, founder of HouseholdMe.com and I’d like to say thank you for dropping by. Like most of you, the first thing I look at before buying something online is reviews or buying guides. By reading what other people say will help me gauge whether or not a product is good or not.  I am trying to help people find answers, solve problems, and get inspired.
