Carbon Filters For All Odors

Of all the senses we have our sense of smell is the most acute. We can detect a foul odor from a distance and it becomes unpleasant to be in the same location from where the odor is emanating.  We immediately try to find the source of the odor and remove it if possible. In addition will usually spray the area with some type of aerosol material designed to mask the airborne odor.

For odors and gases that are prevalent all of the time a more permanent solution is usually required. Activated carbon or granular activated carbon is the commonly used media to remove or significantly reduce airborne odors and gaseous pollutants from over 400 different organic or inorganic compounds.

D-Mark Inc. has been making granular activated carbon products and filters since 1970 and today produces a wide range of carbon and other adsorptive compounds for the removal and reduction of pollutants.

These carbon filters can be used in conjunction with standard HVAC systems or in stand-alone fan powered housings specifically designed for any application. These systems can be created to remove up to 100% of the gases for long periods of time between filter changes. This is important in applications where the gaseous pollutant is harmful or toxic.

D-Mark, Inc. has been making granular activated carbon filters since 1970 and after almost 48 years they are now one of the premier U.S. based companies that offer a wide range of carbon filters for applications in the residential, commercial, institutional, industrial and medical markets.

Dmark Inc. Ahead of the Curve

Dmark Inc. has been in the business of making granular activated carbon media filters and systems for the removal of organic and inorganic odors and gaesous pollutants since 1970. 48 years of being in a specialty niche market business with the same owner and many of the original employees is a testament to Dmark Inc. being ahead of the curve.

Today, digital technology in all its forms is the new method of doing and creating everything. Most of the under 35 age group know little about making anything as they are now part of the disposable economy where we just replace rather than fix everything.

Even schools today have few, if any, vocational programs so providing any type of hands-on skills is becoming almost extinct. So it is amazing that Dmark Inc. has been able to not only maintain its position in the market but also grow its business model using newer equipment and streamlining their production operations so they can produce more product with the same number of employees.

Dmark Inc. is also ahead of the curve when it comes to developing new products or enhancing their current carbon based product line. Dmark Inc. has developed a process for their CarbonWeb and OdorGuard product line that allows for more activated carbon per square foot of filter material than any of its competitors putting Dmark Inc. ahead of the curve in the field of carbon filter development.

In November of 2017, Dmark Inc. moved into a 50,000 + square foot facility to enable them to keep up with the growing demand for their products from an ever-changing customer base.

Dmark Inc. makes a very broad line of carbon and other adsorptive media materials and continues to make metal and carbon filters for the fume-hood appliance market.

D Mark Inc. An American Success Story

Started in 1970 by Jay Kasmark, D-Mark, Inc. makes a  non-sexy line of products made from granular activated carbon, or GAC. These commercial grade odor and gasious pollutant removal filers are used in a wide variety of applications. Up to 400 different organic and inorganic compounds in fact.

We are all familiar with small companies that grew and then were purchased or absorbed into a larger corporation and became just another victim to Corporate growth and acquisition. D-Mark is not one of them.

Make no mistake, making Carbon is a dirty business. There are few, if any, companies in today’s Technology Rich environment that want to engage in this process and there are very few people left who understand how to apply this product for the wide variety of applications.

D-Mark is, in essence, the quintessential American Success story in that the company is still owned and operated by its founder, Jay Kasmark, and continues to grow even at this stage of its existence. In fact, D-Mark just moved into a new 50,000 sq. ft. facility as it had outgrown its original building in Chesterfield, MI. Most companies at this stage of their lives look to stay in their own back yard and not spend more money on a newer facility.

D-Mark is a niche company. They have only a few competitors in North America and many of its bigger competitors dropped out of the market due to its aging technology. However, the demand for the carbon based filter products is growing so D-Mark has more business than ever before and is adding more equipment to enable them to meet the demands of the market.

Smoke Gets In Your Eyes

OdorGuard 300 2" Ring Panel Filter

For many people living in the Northern states Winter will soon be here and with it comes cold temperatures and the opportunity to light up the fire place that has been sitting idle for most of the year.

While many people burn some special logs that keep the chimney from building up layers of carbon, most people burn various types of wood. Wood that smell good indoors but creates a significant odor outdoors.

When the air is cold smoke does not rise well into the air above the chimney exhaust area. In fact, it tends to stay low and even settle down to ground level. When you run the furnace in your home, the HVAC system that is supposed to balanced so the house is not under negative pressure is more often than not, correct. So when the furnace fires up the house draws in air from the outside.

If you live next to a person who uses their fireplace then you may be sharing their smoke in your home and the odor is not pleasant. You can remove some of the odor when this happens by putting in a combination carbon/air filter from D-Mark Inc.  These Ring-Panel filters are effective at both removing airborne particulate as well as odors and gaseous pollutants.

D-Mark, Inc. has been making granular activated carbon products since 1970 and has filters to sized to fit any force air ducted heating/cooling system on the market.  These filters have a very large amount of carbon per sq. inch of filter media making them a very effective tool to remove that odor in your home when smoke gets in your eyes.

Odor Eaters

Air Cleaner Filters

Foot odor has been around since man started walking and found that putting some type of material under and around their feet helped protect them when walking on anything other than sand.

The medieval era saw boots made from animal skins and hard leather with metal posts for keeping them laced up. One would think that the non-breathing animal skin would create a veritable foot terrarium to grow odor creating bacteria. And since bathing was probably a once a week project, I am guessing there was significant odor once those boots were removed.

Odor eaters use an activated carbon based material mixed with baking soda to quickly and effectively adsorb the odor from your feet. It works extremely well but does have a limited life. While some suppliers recommend changing every 6 months we would probably cut that time by 50%. Four times a year would be our recommendation.

D-Mark, Inc. is one of the major suppliers of granular activated carbon in the U.S. They have been making carbon based filters and filtration systems since 1970. Carbon was around during the Medieval days as charcoal. I doubt they considered using it for foot odor but at that time a wide variety of odors were probably more common so foot odor took a back seat.

D-Mark recently moved to a larger facility to increase their product capacity as the demand for their carbon based filters has risen dramatically.  Their new forty plus thousand sq.ft building will allow them to bring in more equipment with higher capacities and better quality control.  D-Mark makes carbon filters for the residential, commercial, institutional, industrial and medical markets. Their vast experience in providing solutions to extremely difficult chemical gaseous pollutants has made them the go-to company for odor and gas pollution reduction.

D-Mark Incorporated

Started in 1970 by Jay Kasmark, D-Mark , Inc. is a highly successful US based manufacturing operation that continues to grow in a market that most would consider old world manufacturing rather than new technology based manufacturing.

D-Mark produces a wide line of carbon based products that are used for the removal of odors and gaseous pollutants from over 400 different organic and inorganic materials. They have pioneered the use of granular activated carbon in a  filter material that allows for a very high capacity of carbon particles for the adsorption of these gases.

D-Mark recently moved from their original facility Chesterfield, Michigan to their new facility in Mt. Clemens, Michigan.  They added over 20,000 sq. ft. of space to accommodate their manufacturing expansion programs and provide even better service for their ever-growing customer base.

D-Mark holds a number of patents for their product line. This includes their CarbonWeb materials and OdorGuard products. These two product types represent the bulk of the wide variety of carbon based filters produced by D-Mark, Inc.

One of the other reasons for D-Mark’s success is their highly experienced and well trained technical sales staff. Most of the employees at D-Mark have been there for over 20 years and with that longevity brings a massive amount of experience  in applying D-Marks carbon filters to any type of challenging application.

D-Mark also has a new website that allows customers and individuals to learn more about the product line and the use of Carbon as an adsorption medium as well as providing an on-line store to purchase most of their products right from their website.

Carbon Filters and 3D Printers

The use of 3D Printers has exploded over the past 5 years with the majority of those in the educational, home and small business environments being of the FDM or FFF type. These 3D Printers use a spool of filament that is made from a wide range of materials such as PLA, ABS, PETG, Nylon, Wood, Metal, Flexible, Polycarbonate, Carbon Fiber to name a few.

Some of these materials such as ABS and ABS/Polycarbonate will off- gas fumes when they are heated to their printing temperatures of 240 degrees  C and higher. ( which is over 430 degrees F). These gases produced from the Styrene portion of the material can be harmful when inhaled in large quantities or over long periods of time.

The manufacturers of ABS filament recommend that the materials be used in a well ventilated area or within an enclosure using Carbon or some other adsorptive media to remove the gaseous pollutants.

D-Mark, Inc. has been manufacturing Carbon filters since 1970 and produces small, compact carbon filters for 3D Printer enclosures. One of them is made by LiteWorld LLC based out of Florida. ( ) These small CarbonWeb filters remove the odors and gases from the printers using a small fan to pull the air from the enclosure both keeping the air in the surrounding environment safe and the 3D printer clean. The use of the enclosure also aids in the printing process when printing materials that are affected by cold air hitting the build platform during the 3D Printing operation.

D-Mark makes a wide variety of Carbon medial and other adsorptive materials for the commercial, institutional, industrial, medical and residential markets.  47 years of experience has put them in a league of their own. They are currently moving to a new location as they have out grown their production space.

Things Go Better With Carbon

Some advertising slogans stick around for many years and even if they have been replaced by  a newer,  catchy phrase product advertisement.  “Things Go Better With Coke” was around for over 20 years and almost every comedian and public group paraphrased this line for their own purposes.

In 1970, D-Mark, Inc.  opened up their doors as a producer and supplier of granular activated carbon for the purposes of removing odors and gasesous pollutants from over 400 organic and inorganic compounds. Their tag line is very simple; “Making Carbon Filters Since 1970.”

Carbon is used in both water and air pollution applications and in truth, things do go better with Carbon. Much of the water used in the production of carbonated beverages is filtered through carbon media to ensure the water is free of chemicals that could change the tasted of the Coke or whatever soda you drink.

In fact, almost every beverage that uses water ( and most do ) has their water filtered or purified prior to adding it to their final product. Think about the water filters you put on your kitchen tap, that has carbon as its main filtration product. Even Keurig coffee makers have a carbon replacement device they recommend for their water reservoir. Why do they want you to filter your water through carbon first before you make that next cup of coffee? Well, they know that much of the tap water has various levels of certain chemicals which can alter the taste of the coffee.

So when we say things go better with carbon we really mean it.

Intelligent Design

There are many things that are found on our earth that we use every day but don’t realize they are natural part of our planets makeup. Coal, oil, helium, phosphates, rubber, cocoa, metals, water, sand, earth, etc, etc. The word man-made is really not completely accurate. Yes we make energy by burning coal but the coal is a natural part of our planet’s composition and the water has been here since the planet was formed. These two easily found natural components allow us to make electricity.

D-Mark, Inc. is a company founded in 1970 that uses cocoa nut shell based granular activated carbon for removal of orders and gases. This intelligent design of using a food source shell for commercial applications is another way we incorporate the natural state in our daily lives.

The use of coal or charcoal or carbon ( all basically the same thing ) for purposes of odor and gaseous pollutant removal has been around since the turn of the century. In 1970 when D-Mark opened their doors. The use of carbon in the industrial market had grown significantly. Not only for removal of airborne gases but also for water purification which is still a large part of the usage for carbon.

Today, D-Mark makes granular activated carbon for residential, commercial, institutional, medical, industrial and military applications. They offer their product in a number of product designs and now offer all their products on their website. This allows individuals to learn more about the background of how D-Mark grew over the past 47 years but also the fact that they can now help remove odors from over 400 organic and inorganic materials.
