Here’s How to Get Rid of Weed Smell (Because No One Needs to Know When You’ve Smoked)

If you’ve ever visited the Netherlands, Canada or one of the states with relaxed marijuana laws, there’s a chance you’ve (legally) enjoyed the mind-altering drug known as marijuana. Weed is great for relaxing, producing a mild euphoria and basically having a really chilled out time — just ask viral sensation Frederick Miller. While the drug does have relaxing benefits, it also features a pungent aroma. If you like to smoke pot, or if you smoke pot for medicinal purposes, but don’t want everyone to know, you probably want to know how to get rid of weed smell.

We’re not suggesting anyone smoke weed illegally. We’re simply saying that even in the most law-abiding households, there are plenty of reasons the average weed smoker may wish to free their home of that identifying smell, much in the same way a cigarette smoker might want to get rid of the associated scent, too. Whether your parents are visiting and you’d rather they didn’t know or you’re hosting colleagues at a dinner party, you’ll need to know how to get rid of weed smell.

Below, we’ve created a how to guide with 10 of the best options for clearing your home and your person of weed’s distinctive smell. There are options for all kinds of smokers, whether you smoke every week, every month or are just looking to try it once in a while without a lasting impact on your home. Take a look through the list, and find the right option for your weed odor removal needs.

1. Conceal Your Stash With Natural Odor Deodorizers

Every college student has tried the old dryer sheets in a paper towel tube trick. But there are far better ways to mask the smell of weed. One of the cheapest ways to ensure no one discovers your stash is to mask the natural odor using an odor deodorizer like this one. Place one of these Marsheepy natural bamboo charcoal purifying bags in the bag with your stash and no one will know you’ve got some of the green stuff tucked away. The sealed linen bag absorbs moisture in the air and holds it inside along with your odors. These are completely natural without synthetic fragrances or harsh chemicals so there’s no need to worry about your weed being contaminated by foreign fragrance, and they only require a 2-hour sun recharge once a month.

2. Don’t Forget About Your Breath

Most people focus on the space in which pot was smoked when trying to remove weed smell. But simply cleaning carpets, clothes and countertops won’t get rid of the smell completely. That’s because, like cigarettes, weed does leave a scent on your breath. To make sure you get rid of every ounce of weed smell, use a strong mouthwash, like the Listerine Ultraclean Mouthwash . As an added benefit, the mouthwash also works to clean your mouth and teeth every time you use it.

3. Use Incense

If there’s one smell which is more recognizable than weed, it’s incense. That’s why it might be a good idea to try and cover your tracks by filling your home with the smell of incense instead. If anyone asks, just tell them that’s incense they’re smelling, and even show them if they aren’t convinced. The Mag Champa Incense is a great option to keep in your cupboard at home. This set includes a range of different scents, including sandalwood, jasmine and sunrise, and with 12-15 sticks in every box, you won’t run out for some time.

4. Clean Surfaces With a Strongly Scented Spray

Although most people consider weed smell to mostly settle in the air and into fabrics, the scent can actually penetrate harder surfaces. That’s why it’s essential to regularly wipe down countertops, furniture and any other fixtures in your smoking spot. Using a strongly scented cleaning spray, like the J.R. Watkins All-Purpose Cleaner will help do double duty in that regard. Not only will the spray clean the surfaces, natural aloe and green tea scent will cover your weed smell swimmingly. The naturally calming scent will also mellow you out even more and the lack of harsh chemicals is better for your health overall.

5. Try a Candle Made for the Purpose

While burning any kind of scented candle is sure to have some beneficial effect on eliminating the smell of weed from your room, the next level up is choosing a candle designed specifically for the purpose of getting rid of that oh-so-obvious weed smell. The Cannabolish Smoke Odor Eliminating Candle uses a natural scent blend which has been perfected over 30 years to eliminate unwanted smoke odors of all kinds. This candle only contains natural ingredients, including beeswax, soy wax and a range of non-toxic plant oils. To get the best results, light the candle 30 minutes before you start smoking.

6. Exhale Into a Sploof

One easy way to deal with the smell of weed is to never let it escape into your home. This method, favored by smokers who would prefer to keep their pot habits undiscovered, involves exhaling through a “sploof.” Such devices turn smoke into clean air. While homemade sploofs use dryer sheets and toilet rolls to achieve this goal, why not try the Sploofy V3 Supermax for a more comfortable and effective answer? It’s lab-tested to remove 99.97% of .3um particles and features a three-stage HEPA filtration system for maximum effect. Plus, it has a cute little stoner ghost on the case.

7. Spray an Air Freshener

People trust air fresheners when it comes to covering up offensive odors in the bathroom, and there’s no reason an air freshener can’t do the same when it comes to ridding your home of the smell of weed. These handy aerosol cans can be sprayed at the site of the problem. They work to eliminate airborne odors and fight bacteria and germs, too. Give the Ozium Air Sanitizer Spray a try. It’s clinically proven to fight odors with an emphasis on removing smoking-related smells, not just masking them like some competing products.

8. Put Odor-Absorbing Gel in Front of Your Vents

Countless stoners have tried to learn how to get rid of weed smell, but this is one cleaning hack that few smokers have considered. Odor-absorbing gels do exactly what they advertise. By placing one of these effective odor-absorbing devices in front of your vents in the room where you regularly smoke or directly next to the source of the smell, the gels work to remove the telltale weed smell from your space. Plus, these wide-ranging gels can neutralize pet odor, stinky trash smells and unpleasant mildew stink, too. Try the Fresh Wave Odor Removing Gel for a well-reviewed answer to the problem. It comes in a handy pot and is free from harsh chemicals, synthetic perfumes and phthalate.

9. Invest in an Air Purifier

Investing in an air purifier, like the One Earth Health Air Purifier , is a great idea as these devices will actually eliminate and neutralize odors directly from the air. Not only will an air purifier remove the piney, slightly skunky grass smell of weed, it can also work on other smells in your home, leaving the air you breathe cleaner than ever before. In addition, the One Earth purifier runs whisper quiet and sports a compact, portable design, meaning it’s great for use at home and can easily be taken to friend’s houses, too. It’s capable of covering rooms up to 500 square feet and sports a built-in, 30-minute timer.

10. Use the Window + Fan Method

If you’ve tried everything else on our list, it may be time to try out a more conventional answer. Start by opening a window (opening two windows will create a wind tunnel effect, which works even better), and then turn on a fan to move the air from inside your room out. It’s a better idea to have a fan with a large stand built-in, like this Honeywell Double Blade Pedestal Fan , so you can set it up, point it in the right direction and leave it running until the room is clear of the telltale smell. This is an effective answer to most bad smells and works well in combination with any other methods on this list, too. Sometimes, when it comes to getting rid of weed smell, the simplest methods are the most effective.

11. Invest in an Odor Control Storage Method

Due to increased popularity and regularity of the substance in popular culture, there are now companies with the sole purpose of creating storage options for frequent smokers. One of them is STASHLOGIX, a brand that’s created somewhat of a weed lunchbox with an odor trapping gasket and liner inside as well as adjustable dividers for different sized buds and a waterproof zipper. On the beach and the tide comes in all over your stuff? Your weed will be safe. It’s also got a combination zipper lock for keeping your stash secure and this product comes with a lifetime warranty so you won’t have to worry about it wearing out and letting the smells loose.

If you enjoy marijuana but don’t want everyone to know when you’ve smoked, learn how to get rid of weed smell for good.

Controlling Smells & Odors in The Grow Room

What’s that smell?

Have you ever been standing somewhere with no one around, and you catch a hint of marijuana smell in the breeze? Even if you couldn’t spot the source, you wouldn’t doubt what your nose told you.

One of the most appealing parts of cannabis is its pungent, unique smell. Unfortunately, that same delightful smell is instantly recognizable and can cause lots of trouble.

A grow room with flowering marijuana plants is a factory for that delicious tell-tale smell, and to protect your girls, you’ll have to make that smell a non-issue.

Today we’ll quickly get you up to speed the options available to neutralize smells made by your plants, and we’ll explain which methods are most effective.

There really aren’t a lot of options when it comes to stopping smells in the grow room. Either you find a way to “scrub” the smells out of the air, or you find a way to cover up the smell.

For a small grow with just 1 or 2 plants, you can usually get away with covering up the smell.

For a larger grow, you will likely need to scrub the air to make sure you’re not leaking any smells that might catch the attention of nosy neighbors.

Here are the main ways to get rid of smells in your grow room:

1. Carbon Filter/Scrubber (Scrub odors from air)

These are hands-down the best option for controlling marijuana grow room odors. Carbon filters (also called ‘carbon scrubbers’) will actually pull the smells out of the air, neutralizing any odors that pass through.

Carbon filters are what you need if it’s important to neutralize the air coming out of your exhaust. A good carbon filter will make sure you never accidentally leak the smell of cannabis out through a window into your neighborhood.

These devices use activated carbon to chemically absorb smells and other impurities from any air that is pushed through the filter.

With a carbon scrubber, you need to set up a situation where the smelly marijuana air is being forced through the filter. In other words, you need to use a fan to push or (even better) pull air through the carbon filter.

The most common way to do this is to set up a carbon filter as a part of your exhaust system in a sealed grow tent, and use an exhaust fan pulling hot air away from your grow area. As hot air is pulled out and away from your plants, the carbon filter scrubs odors from the air on the way out.

Example of a carbon filter set up in a grow tent – this device scrubs all smells from the air so odors never leak outside the tent

Carbon filters are…

  • highly effective
  • extremely easy to maintain once they’ve been set up
  • last a long time

How to Find & Install The Right Carbon Filter

1.) Identify the diameter of your exhaust

Many standard air-cooled marijuana grow lights are fitted with a 6″ exhaust hole (listed as 6″ air-cooled hoods). For most small-scale growers using a tent, you will want to get everything in 6″: including fan, carbon filter, and ducting.

Why 6 inches? 6″ fans are strong enough to exhaust the air from nearly any small-scale grow. Unlike 4″ fans which are often too weak for 4″ carbon filters & will not fit standard air-cooled grow lights. 8″ and bigger filters are generally for more commercial applications; they require extremely powerful (and expensive $$$) fans suitable to moving huge amounts of air from a large enclosed area, plus they can’t be hooked up directly to standard grow lights.

2.) Match up CFM rating between fan and carbon filter

Make sure the “CFM” rating of the carbon filter is the same or slightly higher than the one listed on your fan. This ensures maximum efficiency but also has an added security benefit: it makes sure your carbon filter is only taking in as much air as it can effective scrub for odors.

For example, if the carbon filter says “300 CFM”, your fan should be rated as 300 CFM or just a little lower. A 600 CFM fan would pull more air than the 300 CFM filter could deodorize.

Recommended 6″ Carbon Filter setup

Fits any standard 400W, 600W & 1000W MH/HPS system – learn more about MH/HPS grow lights

3.) Install fan and filter into exhaust system

Refer to the diagram below to see how a carbon filter should be set up in your exhaust system. The carbon scrubber being placed at the back of the exhaust system minimizes the risk of flowering cannabis smell escaping.

Smell Emergency?

One trick to clear a room of smell that I’ve learned will work in an emergency is to put an exhaust fan on top of a carbon filter, and place it wherever the smell is strongest. I’ve done this when I’m cooking cannabis in the oven (which can smell up the house) or if I’ve been smoking and suddenly realized I have guests coming. It looks like this:

You don’t even have to attach the fan to anything, you can just let the scrubbed air go back into the room. It’s pretty amazing how fast this can clear up a smelly area! I learned this from a dispensary owner. Here is an example of a fan/carbon filter combo.

2. Odor Neutralizers (Cover up the smell)

Note: It is recommended you do not place these products in your grow room or tent with flowering cannabis plants. Strong odor neutralizers work so well they can actually reduce or alter the flavor of buds over time. However, these are incredibly effective at neutralizing odors outside the grow area.

Unlike a carbon filter, odor neutralizers don’t “scrub” the smells from the air.

These products are designed to bind with unpleasant smells so that the smell is “neutralized”. Often they also have a very strong fragrance to help cover up smells.

I’ve heard of growers using everything from incense to “bathroom sprays” to cologne to try to cover up the smell of a flowering marijuana plant.

Most household products like wall plug-ins and sprays just aren’t strong enough to cover up the smell of a marijuana grow room for long, if at all.

Also, using these products on your cannabis plants can reduce or alter their natural smell.

Any odor neutralizer or fragrance needs to be constant since your plants don’t stop making their unique flowering scent once they start. Once the smell arrives in your grow room, it basically keeps getting stronger until harvest.

However, there are a few heavy-duty products available that are effective for small-scale marijuana grow rooms.

Sprays, Glade Plugins, etc – Generally these are only effective for a few hours at most. Only recommended in an emergency!

Best spray to cover up smells in an emergency: Ozium Air Sanitizer – this smells very “citrus clean” that seems to do pretty well at covering up cannabis odor without smelling like you just sprayed a bunch of Febreeze. The only thing to keep in mind is a little bit goes a long way. A quick spritz is all you need!

Warning: Never spray any odor neutralizer near your plants in the flowering stage or the smell can stick to the buds!

Recommended Marijuana Odor Neutralizer – Ona Products

Ona Gel and Ona Blocks were originally developed to control the smell inside sewage facilities. They are now available to consumers because they are remarkably effective at neutralizing odors.

Ona products are quick and easy to use. They are effective at covering up smells in a small grow room, though they will only work for a relatively short window of time and must be replaced every few weeks up to a few months.

Ona Gel in the original scent seems to be the most effective for covering up marijuana smells in our tests. With a few flowering plants in a grow tent or closet, you will be able to cover up almost all smells with one or two of these placed outside the grow room.

Never place Ona products in with your flowering plants!

If you use Ona products in your living room, den, or other open areas, no one who enters those rooms will be able to smell any sign of your cannabis plants, even if the plants are just a room away.

But Ona products can reduce or alter the smell of your cannabis buds if they share the same air, so you should never place Ona products in the same area as your flowering plants.

If you need to neutralize the smell coming out of your exhaust, a carbon filter (#1 on this list) is highly recommended. You could also have your exhaust air blow over an Ona product right before being vented outside. It is not recommended to use Ona products in your grow area alongside your plants. Ona products are meant to be used outside the grow area.

How long do they last? It depends on the size Ona Product you buy, as well as the temperature/humidity of your grow area.

Generally, they seem to last at least 4-6 weeks for most growers, which is long enough for a few of these to provide coverage throughout the smelly second half of the flowering stage.

3. Air Purifiers (Air Filters)

We all love the idea of having pure air to breathe. Many air purifiers come with the claim of reducing smells, usually by means of a filter. Do these work to get rid of smells in a marijuana grow room?

It is true that some air purifiers do help remove some smells from the air. However, these are not strong enough to pull all the smells from a grow room. These are only marginally effective.

Therefore, while air purifiers may be a good choice for other reasons, I do not recommend getting one just to try to get rid of smells in your grow room.

4. Ozone Generator – DO NOT GET ONE!

Ozone generators are sometimes added to grow rooms to neutralize smells. Ozone generators claim to remove odors, clean the air, and kill mold and mildew.

Although some growers claim that ozone generators are the best means of eliminating odor, at GrowWeedEasy.com, we strongly recommend against having one in your grow room.

What’s the big deal?

Well, ignoring the fact that Ozone is not as effective as a carbon filter at reducing odors, one problem is that they’re bad for the environment. So much, in fact, that they’re illegal in the state of CA where I live (see: http://www.arb.ca.gov/research/indoor/o3g-list.htm).

More importantly, ozone generators are actually bad for YOU!

Here are just a few of the many links to research from reputable institutions all saying the same thing: Ozone generators are bad for humans!

  • EPA (U.S. Environmental Protection Agency)
    • “In fact, when ozone is inhaled, it can damage the lungs.”
  • OSHA (U.S. Occupational Health & Safety Administration)
    • Ozone is listed as a “Major Indoor Air Contaminant”
  • American Lung Association
    • “Ozone is a potent lung irritant and exposure to elevated levels is a contributor to the exacerbation of lung disease”
  • California Air Resources Board
    • BANNED!
  • Texas Department of State Health Services
    • “Ozone-generating devices should not be used in occupied spaces. Ozone is a lung irritant.”

Some growers claim to have safer ways to use ozone in their grows, such as venting ozone out of the house or making sure ozone only goes into the exhaust. Again, we would strongly recommend against using ozone since in the best case, it’s only doing what a carbon scrubber can do. In the worst case, it’s hurting the lungs of you, your pets and your family!
