How to Choose An Air Purifier to Target Smoke

Once you have made up your mind to get an air purifier and rid yourself of the smoke around you once and for all, the question is, how to choose the right one? Well, here are some pointers for you.

Look For an Air Purifier Labeled For Smoke

To choose the right air purifier to eliminate the smoke from the air around you, the first and foremost thing to check for is if the product itself claims to be able to remove smoke. Most air purifiers do not.

Check the Size of Particles the Device Can Remove

If you still want to verify even further, look for the size of particles that the device is capable of removing and compare it to those present in smoke. If the values come close, then you have a capable device. If not, keep looking.

Go For a HEPA Filter

HEPA filters are not only the most widely used but also the most trusted ones, and that is for a reason. If you’re not sure about what to buy, then HEPA filters are definitely a safe choice. They are designed to trap particles as small as 0.3 microns and are capable of filtering the air a great extent, leaving you with the freshest of air to breathe in.

Coway Airmega 400 steals the show with its true HEPA filter that will be sure to filter particles as small as 0.3 microns. Its ability to filter such small particles will ensure that along with dust particles and allergens; smoke is filtered out from the air too.

Not only does Airmega 400 purify the air over a large area, but it also does so very efficiently, cleaning the air twice every hour.

LEVOIT LV-PUR131 is another true HEPA filter that comes to a close second on this list, with its remarkable capability of efficiently clearing up the smoke from the air in your room. This air purifier is designed to give you nothing less than absolutely purified and fresh air to breathe indoors, and it does so very well.

Review

There are a number of products you can find on the market that will help you reduce smoke from your surroundings. A number of air purifiers come with an array of features, most of them being ones that you don’t need. Such devices may look tempting, but they are way too heavy on your wallet.

This 3-in-1 device will give you the benefit of a pre-filter, an activated carbon filter, and a HEPA filter, putting it at the top in regards to functionality. The device also features a UV-C light that further adds to sanitation by killing germs and bacteria.

Review

Cigarette smoke is considerably more harmful than that from other various sources due to the tobacco ashes. Austin Air HealthMate Air Purifier is certainly the best solution that you can get for all the cigarette smoke.

The true, medical-grade HEPA filter will ensure that about 99.97% of the polluting particles are removed. It will get rid of not only smoke and its odor but also other irritating particles such as dust, pollen, and other allergens.

The air purifier offers three different fan speeds that accommodate the needs of the air quality surrounding you. What’s even better is the 360-degree air intake system that ensures that all the air in the room passes through the filtration. As a result, all you get is fresh air to breathe.

Bottom Line

If you’re looking for a long term solution for the smoke that hangs around you, this is it. It efficiently and smoothly functions to filter your air.

Review

Standard air purifiers would not suffice for commercial-grade use. For that purpose, the Enerzen Commercial Ozone Generator proves to be the perfect product. Its efficiency can be estimated by the number of its successful sales, which mount to over 100,000 units.

The device comes with a fan that is 40% larger than others that will cover a larger area and provide a longer lasting treatment. Its stainless steel filter is washable and saves the cost of replacement.

You will be required to monitor the device for a lot less time with the timer that lasts up to 180 minutes, further making it ideal for commercial use. The ergonomic handle furthermore adds convenience to the design of the ozone generator

Bottom Line

The Enerzen Commercial Ozone Generator is a device that will work ideally in a commercial setup. The large size and extra noise of the device are due to its enhanced function, which is what makes it ideal for a larger scale use. All in all, if you’re getting the job done, temporary inconveniences don’t amount to much.

Pros

Ergonomic folding handle provides the comfort of handling and convenience in Storage

Larger-Sized Fans Help to Cover Larger Areas of Space in a Shorter Time and More Efficiently, Too

What Recent Buyers Report

The features that customers enjoyed the most were the silent performance and how quickly it eliminates smoke. A few buyers also bought units for their office, marveling at how well it cleaned the air and made it easier to breathe. While the device is bulky, some clients enjoyed the look in their homes or bedrooms.

Why it Stands Out to Us

This purifier has a stunning white design, while you can quickly open the front filter for easy access to the rest of the interior. The layers are massive, ensuring that you receive fresh air for the equivalent of a 1,000 square foot room. There’s a discrete cord wrap to keep the cables out of sight, presenting a neat appearance.

When it comes to dealing with smoke, you’ll find a three-stage filtration system. The first is a fabric pre-filter that deals with the largest air particles. This system is followed by activated carbon for the smoke and VOCs, and the HEPA filter works on the smallest substances, such as pollen and dust.

Bottom Line

The BISSELL air320 is an effective air purifier to counteract the effects of smoke. There’s nothing more unpleasant than having it linger in the air for too long, which is why this unit has three stages to ensure the best air quality. You can sleep well at night with the silent performance.

Pros

Three filtration stages

Convenient front panel access

Whisper night mode for a peaceful sleep

CirQulate System that provides air quality readings

Honeycomb activated carbon filter to capture smoke

Cons

Bulky design

Filters are expensive to replace

Are All Air Purifiers The Same When It Comes to Smoke?

While all air purifiers are designed to purify the air from small particles and pollutants, not all of them are efficient enough to get rid of the smoke in the air. In fact, most of the standard air purifiers are not designed for the job of providing smoke-free air. The same goes for removing the smoke odors.

The issue with removing smoke is due to the small size of the particles that compose it. The standard air purifiers are designed to remove particles down to the size of 3 microns, while the particles found in smoke can be as small as 0.7 microns.

It is, therefore, important that if you’re buying an air purifier to get rid of the smoke around you, make sure the one you’re buying is actually capable of doing so.

How Does an Air Purifier Remove Smoke?

Most purifiers have various layers inside that deal with different air particles. This process is known as multi-stage cleansing, as the air needs to pass through separate filters before exiting the unit. What you receive is improved air quality that’s free of dust, pollen, and smoke.

The first stage is pre-filtration where the purifier uses a fan to draw in the surrounding air and block the largest particles. This section precedes the activated carbon, which deals with smoke, odors, and VOCs. Finally, you’ll find a HEPA filter that combats the tiniest particles that are usually smaller than 0.3 microns. Your unit might even have an ionizer that treats the air one last time for airborne contaminants.

What Size Air Purifier Do I Need to Remove Smoke?

When you purchase an air purifier, it usually has a label for what size room it caters to, signified in square feet. You should always ensure that it can cover the entire area, so measure your space before buying the unit. If you’re planning to obtain a single device for multiple rooms, you’ll need to sum up the cumulative area of all the spaces.

You should also assess the clean air delivery rate (CADR). It measures efficiency in terms of cubic feet per minute (CFM). The highest score for smoke is 450 CFM, so ensure you find the best rating based on how much air you need to be cleaned on an hourly basis.

How Often Should I Change My Air Purifier Filter When Filtering Smoke?

Changing your filters is essential if you want to maintain a healthy environment with quality air. If you don’t do it regularly, the system can become clogged and may not perform efficiently. You can also end up with a damaged device.

In theory, you should change the activated carbon layer every three to six months based on how much smoke it clears daily. Pre-filters last about 30 days before they need cleaning or replacement, while the HEPA filter needs changing every year. Of course, reality may differ depending on how hard the machine needs to work to clear the smoke and pollutants.

Best Air Purifier Filter Types for Removing Smoke

You’ll find a wide variety of filters in purifiers these days, but not all of them cater to smoke. For instance, ionizers merely treat the final output for any lingering viruses or bacteria, while other layers eliminate pollen or dust. Here are the three top filters your device should have to deal with smoke. 

Pre-filter

The pre-filter takes care of the largest particles that enter the intake. Some units have fabric layers to ensure that most of the smoke molecules stick to them, leaving the smaller ones to pass through to the inner filters. It’s easy to remove and wash this layer, but you’ll also need to replace it more often than the others.

Activated Carbon Filter

This filter is the one that does the most work against smoke. Not only does it deal with VOCs and smoke particles, but it traps the odors that arise due to it. Whether you’re dealing with cigarettes, weed, or external pollution smoke, the activated carbon filter will eliminate those bad smells for you. 

HEPA Filter

Sometimes, the smallest particles will pass through the previous two filters. The HEPA layer deals with molecules that are smaller than 0.3 microns. While this section generally deals with allergens and contaminants that irritate the lungs, it’s also the last defense against smoke in your home.

People Also Ask

We might have left you with some lingering questions regarding the best air purifiers for smoke. Here are the top FAQs we receive from our readers.

How Effective Are UV Air Purifiers for Smoke?

UV filtration processes help eliminate germs from the air and are therefore not utilized for removing smoke unless they’re combined with other filters. For instance, UV light can turn smoke molecules into water vapor and carbon dioxide but relies on an advanced hydration photocatalytic (AHPCO) technology for the remainder of the process.

What is a CADR Rating in Air Purifiers?

CADR refers to the clean air delivery rate, indicating how efficiently a purifier can cleanse the air in a room. You’ll usually measure this in cubic feet per minute (CFM), which is why you should check this against the room’s area where you’ll place the device.

Do Air Purifiers Help With Smell?

Yes, they do. The devices have activated carbon filters that deal with VOCs and odors. If you find lingering scents after a few months, it means that this layer needs exchanging or cleaning.

How Long Does it Take for an Air Purifier to Remove the Smell of Smoke?

The time it takes for a purifier to remove smoke depends on various factors. For example, what is the CADR, and what area does it cover? How much smoke does it need to clear, and how many air changes per hour (ACPH) are there? It can take anywhere between ten minutes to an hour.

Can an Air Purifier Remove Wildfire Smoke From a House?

Yes, it can, specifically if it has a large pre-filter, activated carbon filter, and HEPA filter. These sections work together to combat the worst smoke, even if there’s a raging fire in your area.
