There are endless reasons why someone wouldn’t want their house to smell like weed. It could be housing rules or a nosy guest coming over that makes someone question whether the aroma of last weekend’s sesh is still lingering. No matter why someone feels the need, sometimes it’s important to leave the smell of weed behind.

Luckily there’s assorted technology available to manage the distinct smell of pot. From products that nullify the smoke to full-out air purifiers, in this day of impending legalization, there are options, baby. These are some of the tried and true classics to get rid of weed smell.

Personal-sized air filter

As a college freshman in the 00s, the best way to smoke bowls on the dorm floor without a resident assistant (RA) busting in was to use a sploof. A sploof is a spent toilet paper roll with a dryer sheet adhered on one end.

After taking a hit, smoke gets blown into the roll and exits through the sploof, taking on a dryer sheet aroma. Now, this won’t work for a joint or a cherried pipe that’s continuously smoking. In fact, back in the dorms, the rules were to snap the bowl in one hit to minimize the excess smell.

While sploof making is still totally a thing, there’s cannabis tech for that too. The Smoke Buddy has been around for years and now it comes in different sizes and colorways. There are even multiple eco-friendly options. This and the Sploofy Pro work in the same way as the original sploof, just a little more incognito than having a toilet paper roll dryer sheet on you.

Truly get rid of weed smell

For the general ambiance of a room or smoke space, turn to cover-up technology. This includes sprays and candles that seek to isolate and replace cannabis aroma. Cannabolish has both.

Cannabolish sprays and candles come in wintergreen and lavender scents. Those fresh smells don’t just cover up what the weed smoke leaves behind– it neutralizes and replaces it. Additionally, the products are made without harmful ingredients like many traditional candles.

Zero Two Four also makes patented cannabis-neutralizing candles in some imaginative scents, though the products are sold out for the time being.

The Cannatonic flavor features creamy leather, Haitian vetiver, and smoked cedarwood for a layered, rich, forest-earth aroma. Additional flavors include luscious cherry, brisk rose, cardamom Forbidden Fruit and self-explanatory Incense & Pepper.

Whether the minimalist or complex aromatic profile is preferred, a candle or a spray could be the key to get rid of weed smell.

Full-on cannabis air purifiers

In the age of summer and fall making room for the wildfire season, most Americans have gotten familiar with air purifiers. There are two readily available types of air purifiers, and they all do different jobs.

While HEPA (High-Efficiency Particulate Air) purifiers effectively eliminate particulates like pet dander and fire smoke, they don’t take out weed smells. For cannabis smoke, a carbon filter is where it’s at. These filters have long been the choice of cannabis cultivators to quiet down the flower room.

The porous filters capture chemicals and some particulates from the air. Volatile organic compounds (VOCs) are some of the chemicals that leave the room smelling like the sesh. Carbon filters from Dyson and Molekule effectively eliminate the smell of weed but are expensive. For someone on a budget, don’t knock the box fan with a carbon air filter taped over it. The whole setup is $30 out the door.

Don’t forget your clothes, hair, and fingers

The air and the room are just one piece of the puzzle. Before stepping out confidently, remember you were also in that room lighting up too. Aromatic cannabis smoke particles are heavier than air, so rather than floating, they sink to surfaces like shoulders and hair on your head. This can leave your clothes and hair with a lingering cannabis scent.

For the hyper-paranoid, consider having a hoodie handy to put over clothes and tuck your hair into. But remember the fingers too. If you were the one breaking up nugs there’s probably a stinky, sticky, icky coating is on your fingertips.

Smelling like weed is one of the few drawbacks of consumption, but it doesn’t have to be permanent. Odor-neutralizing technology has developed to fit the cannabis space, and now there are candles, sprays, filters, and little buddies that can make sure the only loud is in the weed jar.
