How To Use Carbon Filters In Your Cannabis Grow Room

Growing weed at home can be a smelly business. Although cannabis buds smell delightful, such skunky terpenes can also give your hobby away to nosey neighbours. Learn how to use carbon filters to remove suspicious smells from the air and keep you grow private. Then, follow our step-by-step guide to learn how to make your own carbon filter at home.

Growing cannabis indoors comes with a large set of advantages. You’ll have complete control over temperature, humidity, water, and lighting. Such command over your growing space will enable you to boost plant health, optimise yields, and keep pathogens and pests at bay.

However, growing indoors comes with a downside, too. Things can get very, very smelly. You might get used to the pleasant and floral odour, only to be reminded of the intensity of the terpenes when having guests over for dinner. While exposing friends and family to the signature scent of cannabis might not be an issue, landlords and nosey neighbours are an entirely different story.

You can keep your indoor growing operation completely private by removing skunk-y smells from the equation. After looking for a solution to this issue for decades, cultivators finally stumbled across a piece of kit that works remarkably well: carbon filters. Find out how these stealthy devices can eradicate obvious aromas and keep your cannabis grow clandestine.

What are Carbon Filters?

Carbon filters play an important role in any indoor cultivation environment. Aside from growing tents, these devices are also found in air conditioning and furnaces where they help to capture contaminants while allowing clean air to pass through. When it comes to growing cannabis, the “contaminants” in focus are aromatic terpenes. Although these pleasant molecules determine the taste and effects of cannabis, they also unleash a mighty smell!

These filters feature layers of activated carbon, a form of carbon treated to features small, low volume pores. These small holes vastly increase the surface area of the filter, which provides much more space for chemical reactions and filtration to take place.

How Carbon Filters Work

Carbon filters use the principle of adsorption—the adhesion of molecules to a surface—to scrub the terpene-rich air found in grow tents. Because activated carbon possesses a greatly enhanced surface, it serves as the perfect substance for the job. To put things into perspective, a single gram of active carbon features a surface area of 3,000m²!

To ensure terpenes pass through the filter, growers need to create a vacuum in the grow space. Exhaust fans that match the requirements of the carbon filter in use will drag air through the device and out of the grow tent. Adequate suction will force all of the terpene-rich air through the filter, preventing any from leaking out of the sides of the grow tent.

As the smelly air passes through the filter at the correct speed, the active carbon will capture airborne terpenes while allowing other molecules to pass through, preventing the obvious smell of cannabis from seeping out of the grow tent. By attaching ducting to the external outlet of the exhaust fan, growers can direct odourless air out of the nearest window or ventilation shaft.

Where to Put a Carbon Filter in a Grow Room

Carbon filters typically suspend just below the ceiling of a grow tent. Use the following step to position them perfectly:

  • Connect your filter to an exhaust fan that features a compatible CFM (cubic feet per minute) and duct diameter.
  • Secure the two devices firmly together using an airstrip or duct tape.
  • Hang the setup from the roof bars of the grow tent, as high up as possible.
  • Connect ducting to the outlet of the exhaust fan and secure with duct tape.
  • Feed the opposite end of the ducting through the designated hole on the side of your grow tent.
  • Position the ducting outlet near an open window or ventilation shaft.

How to Build Your Own Carbon Filter

Hydroponic stores, hardware shops, and e-commerce websites all offer a wide range of effective carbon filters. However, making your own can reduce costs, and you’ll gain a skill that will come in handy during future growing projects. Follow the tips below to secure the materials you’ll need, and learn how to put them together.

Materials

As a relatively easy task, you’ll be able to obtain all the materials you need to build your own carbon filter after one trip to the DIY store and a brief look around your house. Check the following items off your list as you go:

A) Roll of aluminium screen or chicken wire
B) PVC cleanout cap and PVC adaptor of the same diameter
C) Dryer vent hose
D) Roll of duct tape
E) Role of quilt batting
F) Laundry basket (ideally one with a lid)
G) Activated carbon

Step-by-step Guide

Now that you have all of your materials place them on a large clean work area to begin construction. Use the following steps to create your own working carbon filters out of these random bits and pieces.

  1. Create a tube out of your chicken wire or aluminium screen that matches the diameter of the PVC cleanout cap.
  2. Insert the cap into one end and secure in place using duct tape.
  3. Place the tube into the basket with the open end facing upwards, and trim the tube down so it’s the same height as the rim of the basket.
  4. Remove the tube from the basket. Insert the PVC adaptor into the open end, and seal the two objects securely in place with duct tape.
  5. Fold the quilt batting in two to double its thickness before wrapping two layers around the tube—duct tape everything in place.
  6. Fold more batting in the same manner, and form a double layer around the walls of the laundry basket, securing with duct tape.
  7. Place the tube into the centre of the basket with the PVC adaptor facing upwards. Add more batting to the walls until a 3cm gap remains between the tube and the basket walls.
  8. Fill in the gap with activated carbon.
  9. Cover the top of the basket with more double-layered batting, and cut out a hole over the PVC adaptor.
  10. Attach one end of the dryer hose to the cleanout cap, and attach the other end to your exhaust fan.

When Should You Change a Carbon Filter?

Congratulations, you’ve made your own carbon filter! Not only will you save money, but you’ll also be able to help fellow growers look after their wallets and become more independent cultivators. Hang your DIY filter up in the same way and begin filtering terpenes!

All carbon filters have a set lifespan. Once the surface of the active carbon builds up and becomes clogged, it will lose its ability to absorb more molecules. How long until that happens, you wonder? Well, on average, your DIY filter should keep the air clean for around two years.

However, a sudden increase in aromatic terpenes outside of your grow tent will also indicate the expiration date has come. When that happens, simply remove the lid and exchange the spent carbon with a fresh load. Happy growing!

Weed Filter – A Cleaner, Better Tasting Rip

When it comes to elevating your smoking experience, using a weed filter ensures a cleaner and better-tasting rip.

There are many advantages a cannabis filter has to offer for the recreational and habitual smoker. Inhaling marijuana smoke through a carbon filter improves taste and reduces the number of toxins and carcinogens entering your lungs.

In this article, you’ll learn what makes a marijuana filter a stoner’s favorite essential. So, roll up a fatty and continue reading with us to become the expert on the healthiest way to get lit!

What is a weed filter?

A weed filter comes in many forms. Some filters have been made by hand, while others were perfectly invented for smokers to use for each sesh.

The basic paper filter.

Have you ever seen someone roll a joint? The handmade weed filter used is simply cardstock, folded origami-style, in the shape of a W wrapped in a circle. Airflow is increased through this filter because the cardstock that is being used creates a clear passageway for the smoke to travel within the joint paper, and the way it’s folded keeps the joint from collapsing when saliva is introduced.

Furthermore, this type of smoke filtration stops a bit of the unwanted debris that comes from pulling on the joint. Cleaner rip? We’ll take it. Take a look at what real people are saying about using a MouthPeace weed filter.

How to make a cannabis smoke filter

To make a cannabis smoke filter by hand, you can do one of 3 things:

  • Tear a rectangle shape cardstock and fold in the shape of a W, then wrap it in a circle
  • Insert a glass tip filter in the tip of your joint or blunt
  • Cut a cigarette filter and insert it into your joint or blunt (This method is not ideal with pure cannabis joints as cigarette filters clog very quickly and can reduce THC intake as they are too tight. This is best used for tobacco heavy spliffs.)

These are clever ways to improve airflow but not very effective for filtering out the harmful tar and resin. Toxins still manage to make their way through the makeshift filter and into your lungs.

MouthPeace is a proper filter for cannabis. Its triple-layer carbon filter protects your lungs and also makes your hits taste better. You feel a “cleaner” high. Is your mouth watering, yet?

Why is it important to filter marijuana smoke?

Whether you’ve been smoking pot for the majority of your life or you’re just starting out, it’s safe to say the health of your lungs is taken into consideration before you begin to inhale weed. So, let’s touch on the importance of using a weed smoke filter.

Have you ever wondered what all the smoke is about once you exhale after a large rip? It can’t all be just THC, although we wish…

The big cloud of smoke that follows a hit of weed includes harmful toxins and carcinogens that could be damaging to your lungs.

Furthermore, did you know that tar is a byproduct of burning ANY plant matter, not only tobacco? So every toke you take is laced with nasty tar that gets on your lips and, ultimately, in your lungs.

Many stoners fear that using a marijuana filter reduces THC intake. This is a myth. Thank you weed gods!

THC and CBD molecules are teeny tiny and they make their way through the filter and cling to your lungs. Toxins and harmful bacteria are larger, so the weed smoke filter catches those particles while letting the much smaller molecules pass through.. Once you use a filter for cannabis, you taste and feel the difference. It has been described as a more energized high. Less sluggish and weighed down.

Plus, you can taste the pure cannabis better. Why spend lots of money on marijuana that smells so amazing only to ruin it by not using a carbon filter?

Bong Filter

Another great thing about a MouthPeace bong filter is that you can use it for different variations of smoking marijuana. Joint, blunt, waterpipe, rig, you name it!

To use MouthPeace as a bong filter, you simply insert the MouthPeace filter into the bong mouthpiece. After the first inhale, you’ll see the color of the carbon filter change. And that, my friends, is what isn’t going into your body.

The triple-layer carbon bong filter removes resins, contaminants, and tar from your weed smoke before it has a chance to enter your lungs.

Advantages of using a joint filter

The top advantages of using a joint filter that is built into the pre-roll:

  • It makes rolling the perfect joint easier
  • It improves the airflow
  • You can smoke the whole joint
  • It is healthier for your lungs and more hygienic

If you’re not the Pinterest, DIY type, and you don’t want to start now with making a weed smoke filter, MouthPeace is for you!

You insert your joint into the small end of MouthPeace then inhale and notice the elevated high you feel. Ever smoked a spliff? You’ll know the difference of using a filter compared to not, once you do. One thing to note, the MouthPeace narrow opening is slightly larger than your average joint. You’ll need to either use MouthPeace Perfectly Sized Pre-Rolls, which are properly sized to fit or make your pre-roll tip slightly larger. You can also wrap a bit of paper around standard joints to get a secure fit in your MouthPeace.

How to filter weed smoke

Using a filter for cannabis can be really easy with MouthPeace. But now you have a better understanding of why it is important to filter weed smoke.

A MouthPeace is the perfect addition to your bong accessories and can be used for different methods of smoking pot. Whether you want to smoke a blunt, joint, use a glass pipe, bong, rig, smoke with the fam or solo, you have a way to protect your lungs.

The carbon filter will sort through the THC/CBD and the toxins and only allow the good stuff in.

Now that you have the facts laid out in front of you, you can’t unsee it. Using a weed smoke filter is the smartest thing you can do for yourself. Especially during a pandemic.

Remember, if you’re sharing a bong with your friends, you each need a MouthPeace to keep those germs separate! Be well and stay lifted!
