Smoke definitely isn’t a thing that you’d want to have in your home. Unfortunately, it is pretty difficult to get rid of smoke, but there is a device that could help you with this. The name of this device is an air purifier.

If you happen to be looking for the best air purifier for smoke, then you are in the right place. We have 6 great purifiers to showcase, and with our buyer’s guide, you should be able to easily pick the absolute best purifier from them.

In this article, we’re going to review the following air purifier:



GermGuardian AC4825 22” 3-in-1 Full Room Air Purifier

Up first on our reviews is GermGuardian AC4825 air purifier. It’s not the most functional purifier on the list, but it still has a couple of features to boast.

This air purifier employs a 3-stage filter system, which includes a charcoal filter to capture odors, a HEPA filter to capture 99.97% of microscopic dust and allergens, as well as a UV-C bulb. The purpose of the UV-C bulb is to reduce the concentration of bacteria, viruses, and germs in the air, which would be a handy thing if you have a germ problem.

Not the most powerful air purifier on the list, AC4825 can still boast 167 square feet coverage, as well as clean air delivery rate (CADR) of 108 CFM for smoke, 118 CFM for dust, and 125 CFM for pollen.

A thing that you should keep in mind with this purifier though is that it may emit slight concentrations of ozone. But since this air purifier is CARB-compliant, those concentrations shouldn’t be dangerous to health.


  • Covers up to 167 square feet.
  • The inbuilt UV light deals with gems.
  • CARB-compliant.


  • May emit slight concentrations of ozone.
  • The pre-filter is not washable.

Levoit LV-H132 Air Purifier

Levoit LV-H132 may not have the bacteria-killing capabilities of AC4825, but what is better in it is that it doesn’t produce any ozone. If you don’t really trust even CARB-compliant purifiers, this purifier may be a better option.

The filtration system in LV-H132 is similar to that of the AC4825 purifier, with the exception that this purifier doesn’t have a UV-C bulb in it. But it still has an activated carbon filter, which is the thing that would interest you if you want to get rid of odors.

A nice thing about this air purifier is that it has a nightlight functionality. If you’ve been also looking for a new night lamp, maybe the LV-H132 will be able to satisfy you.

Overall, this air purifier is a good option if you are looking to deodorize air in a smaller, up to 129 square feet room. Particularly, this air purifier could be a good fit for a bedroom.


  • 129 square feet coverage.
  • Has an inbuilt nightlight.
  • Does not emit ozone.
  • CARB-compliant.


  • No washable pre-filters.

Pure Enrichment PureZone 3-in-1 Air Purifier

PureZone 3-in-1 air purifier is a good option if you are looking for a functional air purifier. This model has a couple of things that the previous two don’t have.

The first thing is the inbuilt timer. You could set this air purifier to run for 2, 4, or 8 hours and then shut off automatically. This function would come in handy while you are out of the home, for example.

The other good thing about this purifier is that it has a washable pre-filter. To be fair, pre-filter replacement isn’t that costly, but washable filters could allow you to save some money nonetheless.

The PureZone purifier also has a 3-stage filtration system, including a pre-filter, activated carbon filter, a HEPA filter, plus a UV-C bulb.

With all that being said, there are two things that we don’t quite like about this filter.

First, it emits ozone, albeit at safe concentrations. Secondly, this purifier has a relatively low CADR of 80 CFM. Pure Enrichment claims that this purifier has up to 200 square feet coverage, but the low-ish CADR is going to make the air purification process slower in larger rooms. Keep this in mind.


  • Up to 200 square feet coverage.
  • 2-, 4-, and 8-hour timer options.
  • The UV-C light destroys germs.
  • Washable pre-filter.
  • CARB-compliant.


  • Emits ozone.
  • Relatively low CADR of 80 CFM.

Coway AP-1512HH Mighty Air Purifier

If the functionality of the PureZone purifier wasn’t quite enough for you, maybe Coway AP-1512HH Mighty Air Purifier has what you want. This is a very functional air purifier, mind you.

The most notable thing about this purifier is its versatile speed modes. It has 3 speed settings – low, medium, high – as well as auto and eco modes.

The auto mode regulates the fan speed automatically in accordance with the air quality in the room. This is possible since this purifier has inbuilt air quality sensors in it. There also is a colored LED in this purifier that lets you know how the air quality is in the room.

The eco mode is a quieter and more power-efficient speed mode. It is going to be particularly useful at night when loud noises are undesirable.

The AP-1512HH purifier is also powerful. It has up to 361 square feet coverage, as well as CADR of about 240 CFM. Thus, this purifier is great if you need an increased flow of clean air in a larger room.

Possibly the most remarkable feature in this purifier is its inbuilt ionizer, which is very effective against bacteria. Add to this a washable pre-filter, odor filter, and a HEPA filter, and you get a very effective air purifier.

But do keep in mind that this air purifier emits ozone, albeit at safe concentrations. And yeah, the price of this thing is also pretty high.


  • Up to 361 square feet coverage and about 240 CFM CADR.
  • Timer settings.
  • Has an auto mode and an energy-saving eco mode.
  • The inbuilt ionizer is great against germs.
  • Washable pre-filter.
  • CARB-compliant.


  • Emits ozone.

Winix 5500-2 Air Purifier

Winix 5500-2 Air Purifier is very close to Coway AP-1512HH in terms of functionality, but there are a couple of things in this purifier that you may like more.

The 5500-2 air purifier has 4 speed settings – low, medium, high, and turbo – while all other purifiers on the list have 3. The 4 settings should provide you with more control over air quality, as well as over the purifier’s power consumption.

Another major difference in this purifier is that it employs the PlasmaWave technology. This technology is engineered to safely break down odors, allergens, and other indoor pollutants. However, this results in slight ozone emissions, though the ozone levels should be safe since this purifier is CARB-compliant.

Other than these two things, the 5500-2 air purifier is very similar to the Coway model. It has the same airflow capacity, timer settings, as well as an auto mode. It also has a sleep mode, which’s functionality should be no different than that of the eco mode in Coway’s air purifier.


  • Covers up to 360 square feet.
  • CADR of up to about 240 CFM.
  • Has a sleep mode, as well as an auto mode.
  • Timer settings.
  • Washable carbon filter.
  • CARB-compliant.


  • Does emit ozone.

Honeywell 50250-S Air Purifier

And the last air purifier on our list is 50250-S by Honeywell. This purifier isn’t as functional as the previous two models, but it has some features that you may like about it.

First of all, this air purifier produces no ozone, so if you know that ozone is harmful to your health, this purifier may be a good pick.

Secondly, this purifier is no less powerful than the Winix 5500-2 and Coway AP-1512HH air purifiers. With its 390 square feet coverage and CADR of 250 CFM, the 50250-S purifier should be excellent for odor elimination.

In terms of functionality, this air purifier doesn’t have anything too remarkable. It just has 3 fan speeds, as well as filter replacement indicators. And the filters are not washable, so you’d need to spend money to replace them.

But in the end, this air purifier is an excellent option if you are looking for performance and if you don’t want any ozone in your home.


  • 390 square feet coverage.
  • Up to 250 CFM CADR.
  • Does not emit any ozone.
  • CARB-compliant.


  • None of the filters are washable.

Things to look for in the best air purifier for smoke

Now, how do you pick that best air purifier for smoke among the models reviewed? You need to know what to look for in air purifiers, of course! If you understand what all those terms and numbers mean, you should be able to pick the right purifier with no difficulties.

Let’s now see what matters the most in air purifiers.

Filtration system

The most important component in any air purifier is its filtration system. Modern air purifiers have very different filtration systems, but we can provide you with some general guidelines on how to choose a purifier with the right filtration system.



The very first stage, a pre-filter basically catches the larger debris in order to protect the purifier’s inner components filters and also increase their efficiency.

There isn’t much to say about pre-filters, but a thing that you would want in a pre-filter is washability. Pre-filters don’t cost too much, but in the long run, a washable pre-filter could save you plenty of money.

Activated charcoal/carbon filter

Activated charcoal, also sometimes referred to as activated carbon, is a porous material designed to trap gaseous contaminants. This is the main component to look for if you want to get rid of smoke, as well as from undesirable odors.

An important thing to keep in mind with an activated carbon filter is the availability of replacements, as well as their price. Carbon filters usually aren’t washable, so you’d need to factor in the cost of their replacement in your budget.

HEPA filter

HEPA (high-efficiency particulate air) filters are designed to capture at least 99.97% of the 0.3-micrometer particles. These filters are capable of capturing smaller particles like dust, pollen, and allergens, which makes them excellent at air purification.

There are other types of filters as well, but you should always go for a purifier that has a true HEPA filter. Avoid HEPA-like filters or HVAC filters since they have lower efficiency.


UV bulb

UV radiation is used to sterilize air passing through the purifier. UV bulbs, thus, are very efficient at removing micro-organisms from the air.

The not so good thing about UV bulbs is that they can be harmful to health. Such bulbs are encased in the air purifier and are safe, but if the purifier’s body gets damaged, harmful exposure to UV may occur.


Ionizer purifiers are also very effective against bacteria and germs, but the bad thing about them is that they produce some amounts of ozone. CARB-compliant purifiers should be safe for health, but individuals with asthma and other lung conditions may show sensitivity to ozone and thus should avoid ionizer purifiers.


There also is such a thing as ozone purifiers, but they are designed to produce a significant amount of ozone for entire-house cleaning. The only safe use for ozone purifiers is in unoccupied rooms, so unless this is what you want, you should avoid them.

Room coverage & CADR

Pick an air purifier that is going to have sufficient coverage for your room. In addition, pay attention to how much CADR (clean air delivery rate, measured in cubic feet per minute, or CFM) a purifier has. For example, a purifier with 200 square feet coverage and 150 CFM CADR is going to be much more efficient and quicker than a purifier with the same coverage but lower 100 CFM CADR.

Speed & timer settings

If you have certain requirements for noise, look for a purifier that has varying speed settings. At low speed, your purifier would produce less noise. And besides, variable speed would allow you to control the purifier’s power draw. In this sense, purifiers with air quality sensors and auto speed adjustment are going to be excellent.

As for timer settings, they would allow you to set the purifier for some time and then shut off automatically. This feature would be very useful when you are out of home or are sleeping.

CARB Compliance

CARB (California Air Resources Board) compliance is a very important thing to look for in an air purifier.

First, if you live in California, you would need to get a CARB-compliant purifier. Otherwise, you may run into legal issues.

Secondly, the CARB has strict regulations when it comes to ozone emissions. If an ionizing purifier is CARB-compliant, you could be sure that it is going to be safe for your health. However, keep in mind that any amounts of ozone may be undesirable for those with allergies or lung conditions.

For reference, here is the list of CARB-certified cleaning devices.


When looking for the best air purifier for smoke, don’t just aim for smoke elimination. Get a device that is going to help you with germs, dust, or any other issue you are having at home. Air purifiers aren’t cheap, and you should make sure that you are getting the most value from them. However, if I had to pick an overall, general-purpose favorite among these, I would say the best air purifier for smoke is the GermGuardian AC4825 22” 3-in-1 Full Room Air Purifier.

In addition to the air purifier, you can also try the reed diffuser.
