Activated Carbon Air Filter – What is Activated Carbon?
The activated carbon air filter is widely used in air purifiers today, and it is comprised of a large system of carbon with molecular-sized pores. Owing to these exceedingly absorbent pores, the filter is capable of capturing different types of contaminants, especially gases, odors and liquids.
Advantages of an activated carbon air filter:
- As the most absorbent filter, it is really efficient in absorbing various chemical fumes, gases, odors and smoke. This makes it suitable for housewives or smokers.
- It manages to capture the pollutants permanently
Disadvantages of an activated carbon air filter:
- It doesn’t do a good job in removing dust and other allergens.
- It is not good at absorbing micro-organisms.
As every air purifier has weaknesses and advantages, the activated carbon air filter often works with the HEPA filter technology so that both can be more effective. In fact, activated carbon is often the first step before use of a HEPA filter. The activated carbon air filter not only helps to remove odors, cigarette smoke and chemical fumes, but also big particles like dust, lint, fur and pet dander. By being used first, it also protects the HEPA filter and extends its life. On the other hand, the HEPA works to remove a lot of bacteria, pollen, dust mites and mold spores. Together, the two have a perfect air purifying effect.
These kinds of air purifiers are the mainstream in today’s market. Of course, there are many HEPA-like filters in the market that do not meet the HEPA standard. (According to the HEPA standard, the filter parts need to remove as much as 99.97% of common airborne pollutants as small as 0.3 microns.)
How do you choose air purifiers with an Activated Carbon Air Filter? —
Top Air cleaning machines
Honeywell 50250 is a great Honeywell air purifier product combining HEPA filter technology and an activated carbon air filter.
According to an EPA Air Quality System survey, 72% of allergists recommended Honeywell air purifiers. Honeywell 50250 is round with a 360-degree airflow that achieves the best circulation. 50250 works well in spaces up to 390 square feet.
Whirlpool AP51030K is another great example of an activated carbon air filter with HEPA filter technology. It can handle an area of up to 500 square feet, so it has a higher price than the 50250. They are both on the bestseller list.
