Nothing is more frustrating for smokers than trying to minimize the undesirable effects of weed smoke. While marijuana is becoming increasingly popular for its medicinal properties, it also harms your lungs and fills your home with a distinct odor. Using a clumsy homemade weed smoke filter (also known as a sploof) and dangerous deodorizing sprays to reduce smoke is a huge hassle. On the other hand, procuring the best air purifier for weed smoke is one of the best ways to reduce the unpleasant aspects of smoking indoors.
For those of you with a neighbor who smokes; an air purifier is a great way to keep your living space smelling fresh and clean. Weed smoke and odor are very good at navigating through a building’s walls, floors, and windows. Plus, using an air purifier is way easier than resolving a dispute with your neighbors.
Weed smoker or not, this guide will help you to choose the best air purifier for weed smoke.
Our #1 Pick
The Adverse Effects of Marijuana Smoke
For many people medical marijuana is an excellent way to alleviate a vast array of medical conditions from glaucoma to chronic pain. However, while there seem to be many benefits there are still risks associated with smoking. Generally speaking, the medical community agrees that there is still a risk of lung damage associated with the inhalation of marijuana smoke. This risk is similar to the risk associated with inhaling other carcinogenic smoke, like the smoke created from smoking cigarettes.
There is a common misconception about the danger of the smoke itself, among many people who smoke marijuana. This misconception is that tobacco smoke and marijuana smoke are different because marijuana contains THC instead of nicotine. However, the American Heart Association concluded that secondhand smoke from marijuana might damage blood vessels just as much as secondhand smoke from cigarettes.
Tobacco and marijuana are harmful because they both release chemical pollutants into the air as they are being burned. When these chemicals are not properly filtered, they find their way into your lungs, causing a variety of medical problems.
The positive news is that since the secondhand smoke associated with tobacco and marijuana is similar, the same air purifiers designed to eliminate tobacco smoke can also be used to eliminate marijuana smoke. And, with more states legalizing marijuana; we expect that the need for purifiers is going to continue growing.
Weed Odor is Strong and Distinct
In addition to health concerns, another adverse aspect of marijuana smoke is the smell. Most people can recognize the odor from a surprising distance. Whether it’s growing, stored, or in use… it’s smell carries. When burned Marijuana gives off a very potent scent and many users constantly struggle to eliminate the odor with homemade filtration devices, candles, and aerosol sprays.
Marijuana smokers who live in apartments have the most trouble because they must prevent the odor from seeping out into the hallway and attracting unwanted attention from neighbors and landlords. Even card-carrying users of medicinal marijuana can become self-conscious about the odor. Some simply wish to eliminate the smell out of respect for their friends, family, or even neighbors with children.
As we said earlier, the good news is that the best air purifier for weed smoke will help keep odor and second hand smoke at bay.
Choosing the Best Air Purifier for Weed Smoke
For the most part, your decision will be based on just a few factors. Room size, cost, and filtration technology being the most obvious. Fortunately, many of the products designed to filter allergens like dust and pet dander are also effective for filtering smoke. However, since weed smoke is a more complex pollutant than dust, pollen, and dander you will need to verify that your new purifier is up to the task. But don’t worry, we’re here to help sort through the features that help increase effectiveness.
You will find, in most quality purifiers, a HEPA filter. High Efficiency Particulate Air (HEPA) filters are some of the most advanced filters found in air purifiers. The United States government mandates that a filter must be able to filter out 99.97% of pollutants larger than .03 microns to be classified as HEPA.
This is significant because a large percentage of weed smoke pollutants are larger than 0.03 microns. This makes HEPA filters an excellent choice for smokers. For more details on how a HEPA filter works check out our article on different types of air purifier technologies.
Unfortunately, even the best HEPA filter will not completely scrub the air of smoke particles and odor. For that you’ll need another layer of air purifier technology.
Carbon Activated Filters – Help remove marijuana smoke!
A few paragraphs above, we mentioned that you need to verify that a purifier is up to the task. This is the most critical feature for smokers. Carbon activated filters are a layer of protection that cleans removes many of the things a HEPA filter cannot. Things like odor and chemicals smaller than .03 microns.
From a technical perspective, activated carbon is not filtering incoming air. It absorbs things in the air, like odors, for example. It’s ability to soak up pollutants like a sponge is incredible. In fact, people have us activated carbon for centuries to purify water. And building on that use it was further developed for other uses in the early twentieth century.
What makes it “activated” carbon?
To activate carbon or charcoal, oxygen is introduced in the manufacturing process. By adding oxygen the carbon becomes more porous. In other words, the small holes in the carbon become larger. And once the carbon is activated and the holes are bigger, it creates a sponge for odors and gases to cling to.
This quality is primarily due to the large surface area. Note that one pound of activated carbon has a surface area of 60 to 150 acres. This enormous surface area is what gives carbon the ability to trap the small contaminants that a HEPA filter cannot.
This also means that we can judge how effective an air purifier is at eliminating the harsh byproducts of marijuana smoke by the amount of carbon in the filter. Therefore if you smoke a lot; you need more carbon. On the other hand, if you’re just trying to kill the odor from your weed smoking neighbor you need less.
