Best Air Purifier for Exhaust Fumes


The best air purifier for exhaust fumes uses the world-famous True HEPA air filtration technology to remove PM2.5 and PM10. You want to live long, but vehicular pollution certainly has other ideas. According to Harvard School of Public Health, traffic pollution in 2010 claimed 426 lives in Los Angeles alone! Evidently, traffic pollution kills.


But there’s good news, too. Air purifiers can help minimize your exposure to freeway-related pollution. Here’s a list of 5 great air purifiers for eliminating toxic exhaust fumes (Not arranged in any order)


  1. Medify MA-112 (Wildfire CA Edition, CADR 950)

  1. Levoit LV-PUR131

  1. Hathaspace Smart 5-in-1 True HEPA

  1. Levoit LV-H134 Tower Pro

  1. Inofia (with True HEPA, Wi-Fi Enabled, 1300 Sq Ft.)


Let’s now dive in and learn a few things about these 5 portable room air cleaners. After these air purifiers for toxic exhaust fumes reviews, I’ll tell you more about near-highway air pollutants.


5 Best Air Purifiers for Exhaust Fumes


  1. Inofia (1,300 Sq. Ft.)


Editor’s Rating:4.5 out of 5 stars (4.5 / 5)


The Inofia features a modern, sleek design that purifies spaces as large as 1,300 sq. ft. Its CFM stands at 400 for smoke, pollen, and dust respectively. Evidently, it’s an extra-large room air purifier that moves an insane amount of air. It’s ideal for extra-large living rooms, bedrooms, garages and musty basements. If you live in a small home, you probably won’t need a second air purifier.

It’s a 5-speed machine. And on sleep mode and low, the loudest it ever gets is 27 decibels. On the highest setting, it’s a little louder. But it’s never louder than 52 decibels. And power consumption on speed 1, 2, 3 and sleep mode hovers between 4 and 19 watts. On speed 5, the consumption hits 61 watts, which is unsurprising for a machine that big.

Air enters the machine from the right and left sides. It then passes via a series of powerful filters, and clean air exits via the top. Note: you’ll likely not notice much difference in your air quality immediately. But it works. You’ll very soon start sensing clean, crisp air.

Two prefilters entangle larger contaminants such as lint and hair. Also, the unit contains 2 sets of composite filters. Each set is a type of a 2-in-1 filter. It comprises of a True HEPA filter and an Activated carbon filter. You likely know that most air purifiers use only one set of filters. Not surprisingly, therefore, the Inofia purifies the air much faster and probably better than most room air cleaners.

What does the Inofia remove? The True HEPA filters tackle the soot in the air. Meanwhile, the activated carbon filters step in and suck gaseous freeway-related pollution out of the air. This purifier eliminates dust, pollen, pet hair, dander, mold, bacteria, and VOCs including benzene.

Exhaust fumes, wildfires, tobacco smoke, and volcanic eruptions contain benzene. And benzene is a known carcinogen. This machine should help you eliminate these pollutants. Well, it may not  remove all of them. But it should remove a substantial amount of them. With this air purifier, you should see fewer headaches, less dizziness, and less eye irritation.

This allergen remover is operable manually. However, I’d rather you leave it on auto. It also features a sensitive air quality sensor that shows your room’s real-time air quality situation. You’ll read this data in the device’s LED display. The sensor automatically changes fan speed according to how bad the air quality is.

A filter-change button lights up when it comes time to replace the filters. By the way, does the Inofia use washable filters? No. But the filters last between 6 and 12 months. What filter does the Inofia use? Order the PM1608 filter. Also, the device is Wi-Fi enabled. Meaning you can operate it remotely via a smartphone.




  • Smart air quality sensor
  • Sleek, modern design
  • Long-lasting filters
  • Wi-Fi enabled
  • High CFM
  • Auto mode
  • Quiet on low
  • Replacement filters available
  • Has wheels
  • Programmable timer




  • Filters relatively expensive
  • The APP doesn’t work seamlessly.


Most Inofia users seem to be unhappy with the app. You may not always be able to operate your device via the app. And it seems like Apple Play Store is yet to approve the app.

However, I don’t see this as a deal breaker. The device works well on auto, after all. Plus, the manual operation works well. In addition, it has an auto shutoff timer so it can switch itself even when you’re away. Still, the company should refine their app.




It’s a 24-month warranty. As a bonus, you get a 60-day money-back or exchange guarantee.


  1. Medify MA-112 (Wildfire CA Edition, CADR 950)


Editor’s Rating: 4.5


Most good True HEPA air purifiers filter out contaminants down to 0.3 microns. But great allergen removers such as the Medify MA-112 purify indoor air down to 0.1 microns. Unlike other HEPA air purifiers, the Medify MA-112 uses a medical-grade True HEPA H13 filter.

I’d always praised the Honeywell HPA300 until I leaned about this workhorse. It’s a behemoth whose air purification coverage extends all the way to 2,400 square feet.

Like the Inofia described above, the Medify MA-112 is a great-looking machine that moves the air incredibly fast. With a CADR of 950 sq. ft., this device can clean 1,250 sq. ft. in just 15 minutes! That means it’d circulate the air in a room of that size at least 4 times in one hour. You should get considerably better performance if you install the unit in a smaller room.

Like most air purifiers today, this unit features automatic fan speed adjustment. But
you can still control it manually. When your air quality is good, the machine’s air quality indicator shows blue. When the air quality is “ok,” the sensor turns green. And when the quality is really bad, it turns red.

With the Medify MA-112, untreated air enters the device from the right and left sides. Each side contains a HEPA 13 medical-grade HEPA filter paired up with an activated carbon filter. The carbon filter comes impregnated with loads of carbon for maximum effectiveness.

This air purifier helps users to remove a wide range of contaminants. The H13 filters eliminate dust, pollen, dust mites, soot, and mold. And the activated carbon filters help address odors, smoke, benzene, formaldehyde, NO2, and more.

Are replacement filters available for the Medify MA-112? Yes, they’re available on Amazon as of this writing. Search for “Medify MA-112 replacement filters.”


What I Like


  • Changing filters is a breeze
  • Filter replacement indicator
  • Touch screen controls panel
  • Air distributed 360 degrees
  • Hidden wheels
  • Child safety lock
  • Sleep mode
  • 2 sets of Medical-grade filters
  • Filters down to 0.1 microns
  • Optional ionizer
  • Prefilter washable


What I Don’t Like


  • It’s rather heavy
  • Expensive
  • May produce ozone
  • Filters pricey
  • No certifications
  • Not CARB-certified


As you would expect, the Medify MA-112 isn’t cheap. But if you want to remove 0.1-micron pollutants, pick this option. With a weight of 32 lbs, the air cleaner is much heavier than most. Fortunately, this allergen solution comes with hidden wheels that let you easily roll it around.

But this air purifier may produce ozone. If you’re asthmatic, you’ll want to keep the ionizer turned off.

Hidden wheels: When there are even small changes in elevation, rolling the unit becomes a bit challenging.

I also don’t like that this purifier comes without certifications such as AHAM, CARB, and the rest. At that price, I’d have thought they’d have arranged testing with AHAM. However, the company is working toward having the air purifier approved by California.

In my opinion, the Medify MA-112 is probably the best air purifier for exhaust fumes ever made.




Good news! The Medify MA-112 is now CARB-certified. You can read the full information about it here.

But what’s all the fuss about being CARB-certified?

First off, CARB is an acronym for California Air Resources Board. California is super serious about protecting its residents from substandard portable room air cleaners. If an air purifier doesn’t ship to California, that’s because of one of two reasons.

The first reason might be that the producer is is yet to have the product approved by CARB. Now, CARB isn’t a rubber-stumping organization. They test every product thoroughly to ensure it’s safe for use in the state.

A CARB-certified air cleaning device has been thoroughly tested for ozone emissions and electrical safety. More specifically, the product meets what CARB considers safe ozone concentration levels. The upper limit currently stands at  0.05 ppm. PPM means parts per million.

Note: in-duct whole-house air purifiers that produce ozone are currently not regulated by CARB. Fortunately, the Medify MA-112 isn’t a whole-house air purifier even though it cleans extra-large spaces.

Lest I forget, here’s the second reason an air purifier may not be included in the list of CARB-certified air cleaners. It’s that the manufacturer already knows their product’s probability of being approved by CARB is close to zero. The product likely produces hazardous levels of ozone. Or it won’t endure CARB’s test for electrical safety.

So, if you’re looking to buy an ozone generator or any other purifier that generates ozone,  pick a CARB-certified one. Stay safe.

I’ll keep engaging with Medify concerning pursuing AHAM’s certification. Still, the Medify MA-112 is a great air purifier. It’s what you need to effectively eject nitrogen dioxides, benzene, formaldehyde and other pollutants from your home.



It’s a life warranty with this deal! In addition, you can return a faulty air purifier within 30 days of purchase and get a replacement. Or they’ll process a refund for you. They’ll even pay the shipping fees.

Note: Be sure to register your warranty within 30 days of buying the machine. Also, make sure to use ONLY genuine parts. Otherwise, the warranty will become void. 


  1. Levoit LV-H134 Tower Pro


Editor’s Rating: 4.5 out of 5 stars (4.5 / 5)


The Levoit LV-H134 Tower Pro features a sleek tower design. It looks like a giant, fancy nail polish bottle. You’ll love seeing it every day. It detects air quality variations within 30 seconds and displays real-time air quality numbers. There’s even a dedicated PM2.5 display so you can see how hard your Levoit is working.

The air quality sensor is a perfect ring of light that surrounds the unit’s control panel. The panel itself sits atop the device’s top so you can see the features and read air quality data.

The sensor lights up in 4 different colors that communicate different air quality situations.  If the air quality is very good, the ring turns blue. If it’s good, it displays green. If moderate, it shows yellow.  And if it’s bad, the color becomes red.

The purifier features a 25-decibel sleep mode so you can enjoy restful, uninterrupted sleep every night. The Levoit LV-H134 is among the most efficient PM2.5 and PM10 removers on the market today. Its impressive efficiency has to do with its plane engine-inspired structural design.

Its CFM of 312 enables it to clean up to 710 square feet. A prefilter plucks larger particles from the air. There’s also a True HEPA filter that sanitizes the air down to PM2.5 (0.3 microns).But as explained in this article, some True HEPA air purifiers can filter pollutants down to 0.01 microns.

The HEPA filter helps eliminate dust, pollen, mold spores, bacteria, pet dander, lint, pet hair and more. Apart from these filters, there’s also a carbon-rich filter (activated) for odors, gaseous pollutants, and VOCs removal. Some of the VOCs removed include benzene and formaldehyde. This filter should also tackle NO2 and other NO(x)s. All these are major constituents of road traffic-related pollution.




  • Easy-tap 1-12 hours timer
  • Nighttime mode
  • Has casters
  • Filter may last up to 8 months
  • All drawn in from all sides
  • Quiet on low
  • Sleek, stable design
  • 5 counter
  • High CFM
  • Detects pollution in seconds
  • Ozone-free
  • Energy Star rated
  • Filter available (LV-H134-RF)
  • CARB-certified




  • Not cheap
  • Rolling the unit not always a breeze
  • No mobile app
  • Can be noisy (sometimes)
  • Item doesn’t ship to California as per some users


I feel they should do something about the wheels. If you have some elevation between point A and B, rolling the device won’t be very easy. Maybe they shouldn’t try to cover the wheels with the unit’s body.

Also, the price probably isn’t the lowest it can be. However, you won’t feel ripped off. It delivers. And at that price point, they really should include an app to increase convenience. But the absence of an app will not adversely affect the unit’s operation or efficiency.

Some users found that the LV-H134 didn’t ship to California. But when I dug around a bit, I learned that the unit got CARB’s approval on 5th June, 2019. See approval here.




1-year warranty, but it’s extendable to 2 years. Warranty extension requires registration within 14 days of buying the unit. 


  1. Levoit LV-PUR131


Editor’s Rating: 4.5 out of 5 stars (4.5 / 5)


The Levoit LV-PUR131 is a medium-sized room air cleaner. It uses 3 different types of highly effective filters. This Levoit comes with a CFM of 135 and sanitizes medium-sized rooms up to 360 square feet. In an enclosed space of 360 sq. ft., this purifier exchanges the air 4.5 times. It’s great for asthma allergy sufferers. It’s best for such people not to pick allergen removers whose ACH is below 4.

A mesh prefilter captures particles such as pet hair, lint, and other large stuff. And the True HEPA filter expels up to 99.97 percent of a range of indoor air pollutants down to 0.3 microns. Unlike its sibling the Levoit LV-H134, the LV-PUR131 draws the air from two sides, the right and the left.

By comparison, the LV-H134 pulls the air in from all sides. As you can see, you can stand the both of these machines against a wall. That said, you’ll want to have ample space around the for max performance. The HEPA filter does pet dander, pollen, mold, dust, dust mites, soot, and many more.

Finally, an activated carbon filter helps with the elimination of pets’ odors, cooking odors, smoke, and VOCs. VOCs such as formaldehyde and benzene, both found in exhaust fumes, can cause cancer. So, you need to take urgent steps to protect yourself and your family from these potential killer pollutants.

With this device, you should notice a difference in air quality in minutes. Whether you’re trying to eradicate tobacco smoke or highway-related pollution, the Levoit LV-PUR131 has got your back.

At 15.8 lbs, it’s a lightweight, compact design that doesn’t get in the way. Plus, it’s easy to carry. You can use it wherever you want. And it’s not an eyesore.

Its easy-to-read control panel is on the top. Reading the details on the panel is easy. On night mode, the noise you get is roughly 23 decibels. That kind of noise lulls you to sleep while extracting pollutants so you can sleep like a happy prince.

Does the Levoit LV-PUR131 cool the air? Not really, but the air pumped out feels somewhat cool. However, it’s not like you won’t need a fan in summertime. And will the Levoit LV-PUR131 remove cigarette or weed smoke? Yes, but as thoroughly as you’d like. You really should rely on this or any other purifier for lingering tobacco smoke, though. This article details why you probably should discontinue indoor smoking.

Note: Be sure the device stays bunged at the back before trying to fire up the device.




  • Programmable timer for 1-12 hours
  • Sleep mode
  • Ozone-free
  • Real-time air-quality reports
  • Energy Star rated
  • Auto cleaning function
  • Low energy consumption
  • Night mode
  • Filters available (LV-PUR 131)
  • Pumps out relatively cool air
  • Sucks in air from the front
  • Affordable
  • Light and portable




  • Not Wi-Fi enabled
  • No wheels
  • Some users complained product didn’t ship to California


Though it has no wheels, it’s quite light

Is the Levoit LV-PUR131 Wi-Fi enabled? No, and I don’t like that. However, that doesn’t detract from its effectiveness.

Good news. The company’s released a new model that looks and works pretty much like this air purifier. The new product is Wi-Fi enabled so you can remote control your device. The Levoit Smart WiFi ( LV-PUR131S) is a great alternative to the Levoit LV-PUR131.

But is the LV-PUR131 CARB-certified? Does it ship to California? Yes. The LV-PUR131 got CARB-approved on 9th October, 2017. It should ship to all locations within California.




1-year warranty extendable to 1 or 2 years


  1. Hathaspace Smart 5-in-1


Editor’s Rating: 4.5 out of 5 stars (4.5 / 5)


The Hathaspace Smart 5-in-1 looks sleek and modern. It’s the kind of product you’d like to gift someone on their 18th birthday.

This device is comparable to the Levoit LV-PUR131 in terms of price and coverage. But at this price point, the Hathaspace Smart 5-in-1 stands head and shoulders above every other purifier I’ve seen. The former is designed for cleaning spaces up to 360 square feet. By comparison, the latter’s coverage extends up to 300 square feet.

With a CADR of 160, this unit thoroughly sanitizes the air in small and medium-sized spaces with relative ease. But what makes the Hathaspace Smart 5-in-1 one of the best air purifiers for toxic fumes? What makes it a great solution for vehicular pollution?

The product features a prefilter — the Nano-Cold Catalyst filter — for trapping larger particles. Next, the air forces its way through a massive Cellular Activated Carbon filter. If you live near a freeway, this filter should become your daily companion. Through adsorption, benzene, formaldehyde, NO(x), and other such pollutants enter this filter’s countless micropores.

And if there’s any bacteria suspended in your indoor air, the next filter wages war against it. I refer to the 3rd filter here — the Antibacterial filter.

The 4th filter is the True HEPA filter. This filter extracts 99.97% of mold, soot, pet dander, and dust mites from the air.

Next, we have the ionizer. Well, it’s not a filter. However, ionization is a proven air purification method. So it’s a filter of sorts, our 5th filter. The ionizer pushes out negative ions that neutralize pollutants. And that makes your air feel fresh. But you shouldn’t turn this feature on if you experience asthma or allergy symptoms.

Does the Hathaspace Smart give off ozone? Yes, it does. That’s because it has an ionizer and also features a UV-C light.  I think the proper name for this air purifier should actually be the Hathaspace Smart a 6-in-1. I see the unit’s UV-C light as the 6th filter. Why? That’s because it removes pathogens including viruses and bacteria. But does UV-C light produce ozone? Yes, according to this source. So, turn these two features off if you have asthma or suffer allergies.

It also includes an advanced quality sensor that displays your room’s real-time air quality data. If the quality is bad, the sensor shows a red color. When the quality shifts to “Good,” amber comes on. And when the air quality reaches safe levels, the color becomes green.

Want to know whether your Hathaspace is working? Simple, spray some insecticide or something near it. The sensor shows red almost immediately. And when you’re prepping salmon in the kitchen, you’ll see a movement, too. Even when you’re in the bathroom doing stuff, this air purifier will know and act accordingly.

If your indoor air quality needs improvement, this purifier’s auto cleaning mechanism kicks into gear and resolves the problem. Once the air is clean, the sensor switches back to green.

What about noise levels for the Hathaspace Smart 5-in-1? This is probably the quietest air purifier with such specs on the market. On low, it’s almost inaudible (18dB). The loudest the noise ever gets on high is 43dB. I have seen quite a few smaller and less powerful air purifiers whose noise level went up to 56 decibels.




  • Tons of value for the price
  • Timer: 1-12 hours
  • UV light to exterminate pathogens
  • User-friendly controls
  • Sensitive air quality monitor
  • Removes odors pretty fast
  • Detects odors and VOCs accurately and quickly
  • Portable
  • Affordable
  • Nighttime mode
  • CB, CB, and ROHS, and CQC certified (Chinese certifications)
  • Includes an ionizer
  • Quiet on low
  • Auto mode
  • More thorough 6-stage filtration
  • Battery-powered remote




  • Filters relatively pricey
  • Control lights too bright
  • The controls could be clearer
  • Produces ozone
  • No dimmer
  • Not AHAM-tested
  • Not made in the U.S.
  • No filter change indicator


There’s no way whatsoever to turn the overly bright lights off. And that’s a bummer. However, you can cover it with something at night and enjoy disturbance-free sleep.

Is the Hathaspace Smart AHAM-tested and verified? No. As far as I know, the device isn’t AHAM-tested. However, the China-based manufacturer says it’s been tested. Moreover, the manufacturer says the tests performed are comparable to well-known U.S. standards.

But I honestly don’t know why the product description states that the thing has a CADR of 160. How’s that possible given that AHAM has not tested the unit?  I’ve messaged them for clarification. And I’ll update this review if and when they respond. I think they will respond. Most companies do.

I also feel that at this price point, the company should have included a “change filter” button.




I didn’t find the usual warranty info, but I’ve messaged them about it. I’ll update this section once they respond.

That said, you’ll enjoy a 60-day money-back guarantee. Well, that’s not super exciting considering that some air purifiers offer 90-day guarantees. But I’ve also seen many air purifiers with 30-day guarantees. Heck, I’ve seen 15-day guarantees! Seriously though, don’t buy air purifiers whose money-back guarantee is shorter than 30 days.

I’m about to tell you which among these 5 air purifiers impressed as the best solution for road-traffic pollution. But before I do, I need to keep my promise to you. Find below the info I said you’d get after reading the reviews.


Traffic-related Pollution Numbers Have Been Decreasing


The U.S. banned leaded gas a couple years ago. And that’s dramatically pushed down traffic pollution. But it’s still a concern that needs an urgent solution.

If you live in an area with a scarily high Air Quality Index, you must take action now. One way to confront the problem is to install air purifiers capable of extracting particle and gaseous pollution.


Do You Live Near a Busy Road?


According to WHO, the exposure concentrations people living near busy roads face is 2-3 times what people elsewhere see.

But is there any association between how far from a major road one lives and NO2 exposure? A 5-year study conducted in Australia provides a comprehensive response to that question.

In the study, one group consisted of people that lived less than 200 miles from a major road. The other group comprised participants that lived more than 200 miles from a major road.




This research found a statistically significant mean difference between the two groups in terms of NO2 exposure. Also, the research established a strong association between living less than 200 meters from a major road and a higher NO2 exposure.

All nitrogen oxides are potentially harmful. But the EPA pays particular attention to nitrogen dioxide (NO2). In fact, NO2 is one of 6 criteria pollutants the EPA monitors closely. You, too, should start tracking NO2 levels in your indoor air if you live near a busy highway.

Nitrogen dioxide is the result of a reaction between nitrogen and oxygen under high temperatures. It’s not surprising that cars and other vehicles produce copious amounts of this emission.

So, does the air in your location meet the current national NO2 standards? The EPA in coordination with state, local, and tribal governments strives to reduce NO2 pollution. They identify areas where exposures are too high and start working toward pushing it down.

But your health is your sole responsibility. The buck stops with you. Surely, you don’t want to do nothing. Moving to a less polluted area seems like a good idea. But that’s more like running away from problems. Plus, it doesn’t look like a permanent solution. I mean, aren’t they building new roads all the time? Luckily, you can buy an effective air purifier and solve part of the problem.


What are the Health Effects of NO2?


According to the EPA, exposure to NO2 has both short-term and long-term effects. Short-term exposures may worsen asthma symptoms. These symptoms include difficulty breathing, wheezing, and coughing. You may also experience headaches and dizziness. Too much exposure may even lead to sudden hospital admissions and emergency room visits. 

What about long-term exposures? Long-term exposures increase one’s susceptibility to irksome respiratory infections such as asthma. Children and older people tend to be more vulnerable than everyone else.

In addition, NO2 and other nitrogen oxides  react with other airborne chemical compounds, producing ozone. Such reactions have also been found to form particulate matter, worsening the air quality. Now, ozone is a well-known irritant. It can cause severe problems to asthmatic people. I recommend HEPA air purifiers for people living with asthma rather than ozone generators or ionizers. Evidently, you should act urgently if you live near a busy road.

So, what’s the best air purifier for NO2 removal? It’s one that uses granular activated carbon and True HEPA filters. The Activated Carbon filter would help you remove these molecules from the air via adsorption. And the HEPA filter would help you handle particulate mater.

Well, even the best air purifier for exhaust fumes won’t solve 100% of your air quality problems. But it’ll certainly make a difference.


What’s in TRAP (Traffic-related Air Pollution)?


What chemicals and compounds are found in exhaust fumes? According to ScienceABC, exhaust gases consist of pollutants such as carbon monoxide and nitrogen oxides such as nitrogen dioxide.

Exhaust fumes also contain sulfur dioxide, soot, and hydrocarbons including benzene and formaldehyde. Transportation-related pollution also produces tons of soot.  Inhaling these substances over a prolonged period can have detrimental effects on your health.

Here’s a short air purifier for traffic pollution buying guide to clarify a few important things for you.


A Quick Guide to Choosing the Best Air Purifier for Tackling Exhaust Fumes


You need an air purifier that’ll remove both PM10 and PM2.5. That’s because soot carries these two kinds of particles. Fortunately, True HEPA air purifiers can eliminate these particles. Soot is that black, powder-like substance that vehicles emit.

These 4 tips will help your shopping journey (hopefully).


  1. Select an Air Purifier That Can Handle Gaseous Pollutants


Do True HEPA filters really remove gaseous pollutants? No, they don’t. Gases such as SO2, CO, and NO2 consist of very small particles. These particles will easily pass through any HEPA filter unfiltered.


  1. Pick an Option with an Activated Carbon Filter


An air purifier that combines an activated carbon filter with a True HEPA filter should work fine. No other kind of filter on Earth adsorbs gases as effectively as activated carbon filters do. Make sure to select an air purifier that uses both an activated carbon filter and a True HEPA filter.


  1. Choose a True HEPA Rather Than HEPA-Type Device


Not all HEPA and carbon filters are created equal. I believe you should avoid air purifiers described as “HEPA- like” or “HEPA-type.” That’s because their overall effectiveness fades when compared to that of True HEPA air purification. In fact, HEPA-type purifiers aren’t great at removing particles with a diameter smaller than 2 microns. In other words, they’re not good for PM2.5 removal. Want to check out a few true HEPA air purifiers? Start with these Honeywell HPA300, HPA200, and HPA100 air purifier reviews.


  1. Always Go for Activated Granular Carbon


Shockingly cheap air purifiers tend to use low-quality activated carbon filters. Such a filter is often too thin and contains an abysmally low amount of charcoal. Frankly, such a filter won’t do much for you.

So, pick an option that actually uses activated granular carbon. Avoid devices with a simple sponge pretending to be a charcoal filter. I’d say don’t choose the cheapest HEPA purifier the market offers. In most cases, higher-priced models are the best bet.


What’s the Best Air Purifier for Exhaust Fumes?


The Medify MA-112 seems to me to be the finest portable room air cleaner for toxic fumes from vehicles. It stands head and shoulders above anything else I’ve seen at that price point. You’re looking to remove road traffic pollution.

Vehicular pollution comes laden with benzene, formaldehyde, carbon monoxide, soot, and nitrogen dioxides. You’re looking to kick out PM2.5 and PM10 particle pollution. And here’s the good news: the Medify filters out indoor air pollutants all the way down to 0.1 microns.

This device purifies areas as large as 2400 sq. ft. So,  you’re going to get insane air movements in smaller areas. Whether you’re looking to clean the basement or an extra-large bedroom, the Medify Air ‘Wildfire CA Edition’ MA-112 True HEPA H13 is a great buy. It’s pricey, though. Someone’s gotta pay for superior quality. But if forking out that much makes you shudder, check out other air purifiers on Amazon.
