Frequently Asked Questions (FAQs)
1. What is the difference between a carbon filter and a carbon block filter?
Granular Activated Carbon vs Activated Carbon Block Filters Granular activated carbon filters are made using carbon that has been ground up and is held together loosely inside a cartridge or other container. On the other hand, carbon block filters are made by grinding activated carbon into a fine powder.
2. Do carbon block filters remove bacteria?
Activated carbon filters will not remove microbial contaminants such as bacteria and viruses, calcium and magnesium (hard water minerals), fluoride, nitrate and many other compounds.
3. Are carbon activated filters better?
Used together, activated carbon and HEPA filters can trap 99.97% of small particles 0.3 microns and higher as well as most larger particles, especially spores. Activated carbon filters can particularly benefit people who suffer allergies or aggravation from impure air, including second hand smoke.
4. What do carbon filters not remove?
Contaminants that people most frequently want removed that are not readily removed by carbon filtration are fluoride, nitrates, and sodium. Reverse osmosis and distillation remove all three, so either combined with a high quality carbon filter provides complete treatment.
