Tips for Choosing an Effective Carbon Filter
The Definition of Carbon Filtration
Carbon filtration is based on a filter type that uses carbon for adsorbing smells and gases, for the purpose of purifying the air. This filter can be used along with HEPA filters to improve the way the air is purified. Did you notice the use of the word adsorb? It is not a spelling mistake as there is a difference between absorbing and adsorbing. The word adsorb describes the process through which the molecules of the gases and the odors can stick to the molecules of carbon in the filter. It doesn’t mean that they are absorbed into the filter.
A carbon filter with a large surface area is more efficient than one with a smaller surface area. A larger surface area can adsorb more chemicals. Granulated carbon is the gold standard of carbon filtration. Carbon is poured in the filtration container in a compressed form. In this way, the largest possible filtration surface area is obtained, and the effectiveness of the filter is increased to the maximum.
The Difference between an Effective Carbon Filter and Cheap One
Some of the most expensive carbon filters are also the most effective, while the cheapest ones are the most ineffective of all. Cheap devices cannot even adsorb many chemicals, unless the particles are as large as hair follicles. The reason for this is the lack of power and lack of efficiency. The air purifier brands that are the most effective and that have the best carbon filtration systems are these two: AllerAir and Austin Air. They are also cheaper to maintain than the majority of ineffective systems found on the market. Not only do they have effective carbon filters, but they can also include hefty charcoal and special filters for VOC and smoke.
How to Make the Right Choice
If you have to choose between air purifiers with different carbon filtration systems, the surface area is very important. In a case in which granulated carbon has been used, the weight is the decisive factor. For instance, the surface of a filter that has 24 pounds of granulated carbon is larger than the one with 15 pounds. There are carbon filters that are specifically designed for certain gases and smells. In general, you don’t need special types of filters. You only need them when you have a specific issue with smells and gases.
Another important factor to consider is air circulation. This factor is crucial for the effectiveness of a filter. Air circulation has to be really good. If it isn’t, only some chemicals will be adsorbed by the carbon filtration system. There are four things that you must consider before choosing a carbon filter: always look for quality instead of price; consider choosing granulated activated carbon; remember your exact needs; and don’t forget that the more pounds of granulated carbon exist, the more effective the system is due to a larger surface area.
