Carbon Filter: Size Calculator

.

We prefer Phat Filter.  They are light, use top of line carbon, and come with a built in flange.

IF YOUR FILTER COMPANY DOESNT PROVIDE THE INFO BELOW LIKE PHAT FILTER….. YOU SHOULDN’T BE USING IT. 

Phat filters use state-of-the-art design with the best odor absorbing carbon found in the world to give you the single best, clean-air-producing, greenhouse filter on the market. Phat Filters are made with 1200 mg/g number Iodine, Mongolian virgin charcoal, a higher grade charcoal than the Australian charcoal that our competitors use.

The Phat filter outer surface is covered with more air holes per square inch than other filters thereby giving it a higher rated CFM of air flow and hence, a greater ability to filter more nasty odor in a smaller package. The free flow of air through the outer mesh into our machine packed bed of virgin carbon assures that all air passing through the tough, odor removing carbon exits the filter clean.

The air pumped into our special conical cylinder disperses evenly inside the Phat filter to prolong the life of your filter. There is no air bypassing the carbon bed at any point. Peace of mind through intelligent design! 

Depending on the temperature and humidity around the filter, Phat filters will last up to two years, a full year longer than most manufacturers. A fitted pre-filter will catch any larger dirt particles and keep the carbon cleaner to absorb the nasty odors. The pre-filter can be removed a few times a year for easy machine washing before being reinstalled over the canister. 

Phat Filter carbon filters are cylindrically-shaped and come in many different sizes for ease of application. The highly efficient cylindrical design is tightly packed with virgin carbon. The base of the cylinder has a vortex shaped cone and the outer filter surface has thousands of pores for maximum air transfer. Phat Filters are smaller and easier to handle thanks to their lightweight aluminum shell and the extremely porous carbon used. Phat Filter carbon filters are the obvious choice for thousands of professionals and hobbyists world wide because the Phat name means Quality You Can Trust. 

Myth:

The heavier the filter, the better the output.

Reality: 

Weight has nothing to do with filter output. It’s the quality of carbon that counts. Although Phat Filters are light, they deliver a power-packed performance. Don’t be misled by other filter manufacturers who will try to coerce you into buying their inferior product just because it is heavier or they claim to have carbon of equal quality. 

What determines filter efficiency?

Filter weight has no bearing on its performance. Other filters are heavier as they contain many impurities like volatile wastes, moisture, and ash in addition to carbon. Ash and volatile wastes do not contribute at all to the carbon’s absorbing ability while moisture actually reduces the adsorption ability of the carbon. 

The quality of carbon also contributes to its adsorption efficiency. Most filters use pelletized carbon. This type of carbon contains bonding agents, which increases its weight but reduces the actual amount of fixed carbon per gram, which is the real factor behind a filter’s adsorption capacity. In simple terms, other carbon pellets are glued together and glue weighs a lot but doesn’t filter anything. 

How pure is the carbon in genuine Phat Filters?
 
Genuine Phat filters have close to 90% pure carbon. That’s the highest fixed carbon content per gram of any carbon on planet Earth. Every batch of carbon is graded and tested before being sent to Phat Filter for production. 
 
Does the carbon used in genuine Phat filters have any moisture?
 
Phat filters understand how important it is for the carbon not to contain any moisture since that reduces the filter life-span. While it is impossible for the carbon to have zero moisture, genuine Phat filters are guaranteed to have less than 2% carbon moisture. Phat Filter refuses to compromise on quality and insists on using only high quality components for their products. 
 
How does activated carbon improve Phat filters?
 
Phat filter uses 100% virgin carbon that was run through the activation process in a specially constructed kiln. The activated carbon is then tested independently in a laboratory to ensure the highest consistency and purity. 
 
What is the contact time in genuine Phat Filters?
 
A filter’s contact time is the time taken for carbon to completely purify the contaminated air. The carbon in Phat filters has a contact time of just 0.05 seconds, one of the shortest contact times compared to the carbon in other filters. This gives Phat filters a massive boost over their competitors allowing them to produce a lighter filter with a smaller carbon bed that is still superior in purifying the air. University-tested results have demonstrated this with Phat filters having a smaller carbon bed width. 
 
What makes genuine Phat filters so light?
 
The Meso pore carbon used in Phat Filters has a low density. Its large pores create large pockets within the carbon making it ultra lightweight. Phat filters are the world’s lightest carbon filter per ft. 2.
It is up to three times lighter than any equivalent alternative. Phat filters are so light you can install it yourself with no trouble.

Carbon Tests

As the official manufacturer of the range of Phat filters, we make use of top quality virgin carbon and unlike some manufacturers do not cut corners or make use of inferior carbon in the production process. That’s why our filters are among the most popular filter systems in the world!

*Note: Charcoal is tested for quality in a few standard ways around the world. We have the results for our quality virgin charcoal carbon in all 3 standardized test values:

 

  • Iodine Test Number 1200 mg/g
  • Butane Test Number 25.97 g/ 100g C
  • CTC Test Number 66.74

 

The air-filtering products offered to YOU, our consumer, are world class. Genuine Phat filters adhere to strict guidelines with special emphasis on quality control of the product. For this reason, leading labs use our filters over other choices.
