Charcoal/carbon activated filters are filters made from activated carbon, a form of carbon that has been treated to have a large surface area and pores. This allows it to effectively trap and remove impurities and contaminants from air and water.
Charcoal/carbon activated filters work through a process called adsorption. When air or water passes through the filter, the activated carbon attracts and traps impurities, such as chemicals, gases, and odors, onto its surface. This leaves the air or water cleaner and purer.
There are several benefits to using charcoal/carbon activated filters. They are effective in removing a wide range of impurities, including volatile organic compounds (VOCs), chlorine, and heavy metals. They also help improve the taste and smell of water, and can help reduce allergies and respiratory issues caused by pollutants in the air.
The lifespan of charcoal/carbon activated filters depends on several factors, including the quality of the filter and the amount of impurities it is exposed to. Generally, they can last anywhere from 2-6 months for air filters and 6-12 months for water filters. It is important to follow the manufacturer's recommendations for replacing the filter.
While charcoal/carbon activated filters are effective in removing many impurities, they are not able to remove all types of contaminants. For example, they may not be effective in removing bacteria or viruses from water. Additionally, they can become saturated and lose their effectiveness over time, so it is important to replace them regularly.
