The efficacy of a carbon filter depends not only on its particle size, but also on the rate of flow of fluid through the filter. Typical particle sizes which can be removed by carbon filters range from 0.5 to 50 μm. Specifications Įach carbon filter is typically given a micron rating that specifies the size of particle which the filter can remove from a fluid. They are not effective at removing minerals, salts, and dissolved inorganic substances. When filtering water, charcoal carbon filters are most effective at removing chlorine, particles such as sediment, volatile organic compounds (VOCs), taste and odor. It is also used in cigarette filters and in the EVAP used in cars. It is also used in a number of other applications, including respirator masks, the purification of sugarcane, some methods of coffee decaffeination, and in the recovery of precious metals, especially gold. Common uses Ĭarbon filtering is commonly used for water purification, air filtering and industrial gas processing, for example the removal of siloxanes and hydrogen sulfide from biogas. One gram of activated carbon has a surface area in excess of 3,000 m 2 (32,000 sq ft). Activated carbon is typically used in filters, as it has been treated to have a much higher surface area than non treated carbon. As a result, the substrate has a large surface area within which contaminants can be trapped. The substrate is made of many carbon granules, each of which is itself highly porous. In many sips, it allows better airflow and avoids splashes.Filtering method Air purifier HEPA filter with an activated carbon section in the middleĬarbon filtering is a method of filtering that uses a bed of activated carbon to remove impurities from a fluid using adsorption.Ĭarbon filtering works by adsorption, in which pollutants in the fluid to be treated are trapped inside the pore structure of a carbon substrate. Cross: It uses a downstem filtration and cross-shaped tubes designed like the tree type.However, they could be adjusted sideways in bongs with open downstem. Generally, they’re positioned vertically. Barrel: This type has a barrel-like appearance and more holes than most percs.

It has horizontal and vertical slits, allowing greater diffusion.

Matrix: This perc has a cylindrical shape and focuses at the center of the bong’s base.In addition, it enables users to take smooth hits. Swiss: This type has a complex set of holes and an unlikely design that allows powerful diffusion.Furthermore, the number of diffusions defines the quality of hit it may produce. It has several slits in control of the quality of diffusion. Showerhead: This perc has a long tube attached to the main chamber.Many tree types emit a lot of small bubbles. Tree: This type is made of tubular arms that branch out like a tree.

Its filtration and colling properties depend on the number of chambers in each pair. Honeycomb : This perc typically comes in pairs.Inline style is believed to offer a more heightened flavor because of the dispersal of the smoke when it passes through the holes. Inline: This type has many holes placed in a linear pattern.In some cases, the portion with slits is submerged underwater inside the bong. Downstem : This refers to a generally small glass tube with slits that allow the creation of bubbles.Relatively comfortable, this mask filters out 95 of airborne particulates. Take a look at all the different types of bong filter systems you can have for cooling. A disposable respirator for wildfire smoke and dust. In our experience, we found the cleanest smoke possible was with a Mooselabs carbon bong filter, ice, and a powerful water filtration system. Depending on how your glass was cut (generally how many slits or holes) determines the number of bubbles created when you inhale. There’s a lot that goes on in the water chamber of your bong.
