Odor Eliminator: How to Get Rid of Cannabis Smell in Your House
Friday February 7, 2020
F or most cannabis consumers, there is no better, safer, or more enjoyable place to smoke weed than in your own home. After all, where else can you find a couch, a bed, a refrigerator and a TV all so close at hand? (Probably at an Ikea or a Sears showroom, but they won’t let you stay there and smoke, even if you ask nicely.)
Let’s face it, smoking marijuana at home is pretty much the best. Besides the convenience, you don’t have to worry about bothering anyone else with your smoke, driving anywhere, or interacting with anyone besides the friends you have over (and maybe the person delivering the food you ordered, but they’re probably cool.)
However, while smoking weed at home clearly rules, your home smelling like cannabis smoke afterwards does not.
Maybe you have company coming over or live with someone who doesn’t indulge. Or maybe you just came back from an out of town trip and are reassessing your place with a fresh pair of nostrils. Whatever the reason, getting that weed smell out of your home can become a priority and PotGuide is here to help. Luckily, there are plenty of ways to go about exorcising the ghosts of bowls past from your home, whether you only have an hour to clear out the smell or have a couple of days to erase it completely.
Eliminating Weed Smell from Your Home with Less Than an Hour
If you’re in a desperate hurry, don’t panic. Even if your boss, your landlord, or your parole officer called on their way over for an unexpected visit, (or all three are coming because you are terrible at planning a dinner party), there’s still hope. Yes, your place may currently reek like a wet wool poncho after a Phish concert, but that can change quickly.
First, open up all your windows and doors. Get some fresh air in there and get it circulating. If you’ve got a ceiling fan, yank down on that chain and get those blades spinning. If you have a rotating fan or a box fan, plug it in and face it out the windows. The closer to the window frame you can put the fan the better. Empty out all your ashtrays, dump the roaches, flush your bong water, and take out the trash. Next, douse the place with a spray air freshener. Your place may now smell like a spring meadow that someone left a wet poncho from a Phish concert in the middle of, but there’s enough plausible deniability that you can skate by.
Cleaning Cannabis Smell from Your Home When You Have a Day
Say you have a little bit more time. You’re still hosting that dinner party for your boss, landlord, and parole officer (you really should have planned this better) but it’s happening tomorrow. With that much time, you have your pick of methods to get that cannabis smell out of your place.
The age old trick. While incense has been historically used in religious ceremonies, it’s also great for masking any number of odors. Grab a stick or two, find a bowl or other holder to catch the ash, and light it up. The pungent smell will mask any odor, and maybe you’ll seem cultured and refined.
If you’re not feeling the Eastern temple vibe, scented candles are a more Western way to cover for whatever joint spirits still haunt your place. Like incense, you’ll cover the smell.
However, with scented candles you won’t have to deal with ash residue. You’ll also have a wider selection of scents to choose from, depending on if you’re in a New England Beach or Sandalwood kind of mood.
Air Freshener Plug In
If you don’t want to deal with fire at all or have to leave your house for a while, plug-ins will cover any odor. Plus, there’s the added benefit of a constant supply of fresh smells to cover any marijuana odor that might be trying to stage a comeback.
Ridding Marijuana Odor from Your Home When You Have a Weekend
If you’ve got some time on your hands – say on a weekend of chores, or while you’re doing some spring cleaning – then get some brushes, rags, and buckets together and put some music on the stereo. Or a Netflix show that you can tune out, most likely about baking or true crime.
Thanks to gravity, nearly everything eventually ends up on the ground. That’s also true of smoke and if you’ve got a carpet, that’s where that odor will remain.
Vacuuming will take care of a lot of the smell, but if you can’t remember the carpet’s original color beneath the spilled bong water and grubby haze, or you’re trying to get your deposit back, you’ll need a carpet shampooer. Luckily, many grocery and hardware stores offer them for rental and they’re pretty easy to use. Just pour some hot water and detergent into the tank, flip on the power, and watch the magic as it returns your carpet to its original, fresh condition.
Next, get some Lysol or other cleaning agents and give all your hard surfaces a swipe. Old resin, crumbly charred bits of weed, and sticky bits of tar all add up to one overwhelming odor of old weed. Once they’re wiped up you’ll be surprised at the difference it makes. Finally, finish it all off with an odor remover. While air fresheners may mask the smells that can come right back, odor remover spray will go one step further. These sprays and absorbent pillows will suck the cannabis smells out of the air rather than just covering for them.
How to Prevent Weed Smell in the Future
If you’re looking to avoid having your home smell like cannabis in the first place, concentrates are a safe bet, odor wise. However, if you’re loving the flower for its terpenes and cannabinoids and want to keep your smoking au natural, a dry herb vape is a great compromise.
Dry herb vapes are relatively inexpensive on the low end, with handheld devices retailing for less than $150 on the lower end. Because dry herb vapes vaporize the terpenes and cannabinoids rather than burning up the flower, there’s no smoke and barely any smell. This keeps your place smelling fresh. As an added bonus, when you’re done smoking you can use the leftover “ABV” for edibles or tinctures.
In order to keep the weed smell from settling in in the first place, be sure to blow your smoke out the window and take your trash out regularly. Empty your bong water after you’re done using it, for odor and for health reasons, or smoke in the bathroom with the shower and the fan on. Finally, keep your weed in airtight containers to keep those terpenes contained. With a little precaution and a little extra effort your place will keep smelling fresh.
There’s no reason to have to choose between smoking up in the privacy and comfort of your own home and having to live in the aftermath of your pot session. Just follow these simple steps and you’ll be able to strike that balance with ease.

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.

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
- 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!
