Weed Smoke Eater & Odor Control

Controlling the smoke and odor from weed smoke is the job for a good weed smoke eater. LakeAir manufactures several products that can efficiently accomplish this task. 

The Secret to Removing Weed Smoke & Odor

Hemp plants contain terpenes

Cannabis has at least 16 different terpenes associated with it. These terpenes are a big part of what makes Pot smoke so difficult to control. Terpenes are classified as a volatile organic compound (VOCs). In the state of Colorado, Cannabis cultivation is thought to produce as much as 3.5% of the total VOCs. The State has noted that absorption media does a great job at removing dangerous VOCs from the air.

 This complex plant  warrants a complex product to control the gasses and odors emitted from the plant. These gasses are produced by both growing and smoking the plant. So whether you grow, smoke or both a good filter media makes sense.

The most important ingredient to the secret recipe of removing pot smell is a media that has the ability to absorb the complex gases. Activated Carbon does a fair job on its own, but another compound can be added to the media to make it more effective.  The second part of the secret is long time exposure to the absorption media. 

Cannablend, LakeAir’s product of choice for weed smoke odor removal has the complex nature required to be effective. LakeAir’s powerful smoke purifiers for weed provide a sufficient number of ACH (Air Changes per Hour) to be effective. The combination of proper absorbing media and sufficient air flow is the secret formula you need to keep your home free from weed smoke and odor. These powerful air purifiers will work well on all smoke associated odors. Its not only weed smoke to be concerned with, but also cigar smoke and smoke caused by the recent rash of wildfires.

Why Cannablend?

Cannablend is a special media blend sold to LakeAir by Hydrosil International LTD. Hydrosil is one of the foremost companies  providing filtration media for remediation, water and air filtration. Cannablend is a media blend of activated carbon and zeolite. Zeolite is a naturally occurring crystalline compound with over 40 different varieties. It is also commercially produced on a large scale for filtration purposes. Recently zeolite has been reported to work well as a soil additive. It improves water conservation and nutrient retention.  Just as it cleans the air, zeolite can improve the ground enhancing the harvest of many plants including hemp. 

 Hydrosil impregnates zeolite with potassium permanganate. Potassium Permanganate is especially good at absorbing acetic gasses, aldehydes and amines.  adding this cleansing to zeolite creates a super absorption media, called Cannablend. Because cannabis’s structure is made up of many amino acids, when it is burned (smoked) is releases acetic gases. The  amino acids from the terpenes turn to a gaseous form. Luckily these long chain gases are readily absorbed by the specially impregnated zeolite.  Cannablend is excellent in helping a marijuana crop grow as well as protecting us against smoke and odors.

How Much Airflow?

Gases are very small particle. These ultra small particles can slip by both zeolite and activated carbon. Every time they pass through the odor control media there is a chance they will be absorbed. The longer they are in the media bed the greater the chance of their removal from the air stream. 

As a rule of thumb we suggest 8 – 12 Air changes per hour to remove odor gasses from the air. Some gases are more easily removed. The acetic gasses from weed are not in this category. It takes far much longer to remove them from the air. So, it is important to increase the time these odorous gases are in contact with your filtering Media.   

There is a handy air flow calculator on our website. If you would like to calculate the number of CFM (cubic feet per minute) of air flow that is required to achieve 8 air changes per hour in a room size, please visit this helpful webpage.

The MAX-700-420 is the king of air circulation. 650 CFM of power will do an awesome job of removing pot smoke from a room. A larger room is well served with unit. The 300 gram filter is undersized compared to the HEPA model. If you are more concerned about smoke than odor, the MAX-700-420 is the unit for you.

Maxum HEPA-420 is the marijuana odor killing giant. The Maxum HEPA-420 utilizes a thinner 2.6 inch HEPA filter. It has all the efficiency of any LakeAir HEPA filter, but it is thinner and therefor has a shorter replacement cycle. Heavy smokers should plan on replacing this $180.00 HEPA filter every 6-9 months. The room that is saved by the slimline  is dedicated to more Cannablend. 3 times more Cannablend is packed into the Maxum Cannablend 2.5 filter. 900 grams of weed odor absorber will help keep your hobby on the down-low.

Commercial & Public Cannabars

Commercial locations dedicated to providing a safe and legal place to enjoy pot are know as Cannabars. These establishments are popping up across the United States. From San Francisco’s Moe Greens  to Virginia Beaches’ Queens Green Apothecary.  Cannabis Entrepreneurs are opening new establishments most everywhere cannabis has become legal. The University of Colorado Boulder is offering a course designed especially for those interested in making a living through dispensaries and cannabars. The Cannabis Entrepreneurship Academy started in June, 2021.

There are a myriad of things you need to do before you can open a cannabar or dispensary. Licensing, Security, Financing, and Location. As of August, 2021 only 6 states ( Alaska, California, Colorado, Illinois, Massachusetts, and Michigan) allow onsite consumption in licensed cannabis consumption businesses. All of these states allow local communities to add further conditions to on premise smoking. Many of these local codes for strict air purification to call for removal of smoke and odor. 



LakeAir Commercial Cannabis (Weed) Smoke Eaters for Cannabars

LakeAir Commercial 420 Line

The LakeAir Commercial 420 line features heavy duty construction. All Steel is the backbone of the 420 line. 14 gauge frames surrounded by 18 gauge powder coated and vinyl clad steel make for a commercial product built to last. We don’t scrimp on materials, and we don’t build  them cheap. Our Designs are built around product efficiency and easy to service standards. Drop down panels and easy opening doors allow you to quickly maintain the filters of the 420 line. A high level of quality is what you expect and get out of a LakeAir brand wee smoke eater.

LAFC-RC2 420

The LAFC-420 products feature 1000 gram Cannablend filters. Expect 3 months of odor protection in the average establishment. The heavier the smoking the more frequent filter changes will be required. The LAFC-RC2-420 provides up to 1500 CFM of smoke and odor air purifier. This air purifier for weed smoke requires 11 inches of head room above the drop ceiling. It can also be hung from the ceiling by chains or cables. For a more dressed up took ask about  custom vinyl skirting.  

The LAFC-RC2-HEPA-420 has the 1000 gram zeolite / carbon blend just like the electrostatic model. Due to higher filter backpressure the HEPA-420 moves 900 CFM (cubic feet per minute) of purified air. Like its electrostatic twin the smoke purifier for weed requires 11 inches of head room. Both models can also be secured directly to the ceiling with mounting brackets. 


The LA2-420 models features larger Cannablend filters. The vertical filter alignment lends itself to larger zeolite media beds. These provide even more of what you expect of a air purifier for weed smoke. The 3000 gram stand alone filters measure 16″ x 20″ x 4.5″. The multi chamber design forces odor laden air through a treacherous maze of odor absorbing media. As the air passes over and through the filter the gases released by smoking pot get absorbed leaving you with smoke and odor free air. Each pass collects more of the terpene gases. Multiple recirculation passes are required remove all unwanted gases from the air stream.

LA2000-420 has a radial fan design. This allows for 1200 CFM of air flow. The unit comes standard as a 2 speed system. You can order this model wire for variable speed control if you wish. At the 105 pounds LA200-420 is easily hung from almost any ceiling.

LA2-RC2-420 implements True HEPA weed smoke eater filtration. HEPA filtration removes more smoke in a single pass. It also slows the air flow considerably compared to an electrostatic model. The slower air speed affords a longer residency time ( the time gases are in contact with filtration media) and provides better odor control for each cycle. The LA2-RC2-420 mounts easily to a cart as do all LA2 models. Cart mounting allows for quick movement to areas where extra air filtration is needed.

The LA2-RC2-420 VOC Extractor is made specifically for capturing Cannabis Odors. This unit brings 6000 grams of Cannablend to the game. Most often this odor killer is used in grow room to control the odor of the blossoming marijuana crop. The filtration provided does a phenomenal job at removing terpenes from the air but offers no smoke control.

Cannablend Replacement Filters

The 420 line leans heavily on the special Cannablend filters made for this great selection pot smoke eaters. These weed odor removing filters are made in the USA. We keep them in stock for quick delivery. On average, LakeAir Cannablend filters are delivered in 1-3 days. Many odor removing air filters are sold as huge filter beds. These filters offer larger amounts of carbon, and sometimes even zeolite. However these filters do not expose the air to as much pot absorbing media. The air passes over the bed. Our filters force the air to come into more direct contact. Our filters don’t last as long, but they absorb far more odor. When carbon and zeolite have absorbed all the gases they can they need to be replaced. Do you want to remove just a little odor over a long time or get the job done now? A well designed weed smoke eater will remove as much marijuana odor as is possible.
