What Is Activated Carbon Filter?

The Complete Trinity pair (pre-filter, HEPA) that will cover all home airborne pollutants. Activated carbon filter is available in most HEPA air purifier to trap smoke and fumes. It may be a one-dimensional filter, it can target contaminants that no other filters could. So what makes a good carbon filter? How does this odor eliminator works? What about charcoal filter? Are they the same? Let's find out.
Short answer
Activated carbon filter remove smoke and odors.

 

What Is The Function of Activated Carbon Filter?

Activated carbon filter or deodorizer is specifically designed to absorb smoke and odors. Available in most carbon air purifier in the market. with This includes:

  • Cigarette smoke
  • Vape
  • Carbon monoxide (CO)
  • Carbon dioxide (CO2)
  • Chemical fumes
  • VOCs
  • Radon
  • Ammonia
  • Cooking smell
  • Mold stench
  • Pet odor
  • Urine smell
  • Diaper odor
  • Haze

Most carbon filters are made of charcoal or cheaper deodorizing materials like baking soda. Premium filter might consist of impregnation, alumina, potassium permanganate, coconut shells or coal. The odor neutralization process began when smoke particles are pulled into the carbon filter. The absorbent compound in the filter will absorb the impurities via chemical adsorption. This leaves the smoke contaminants trapped permanently inside the filter leaving only clean, fresh air out.

Can You Wash Carbon Filters?

No simple as that. Most carbon filters are not reusable and must be replaced when it reaches its end of the lifespan. Same goes with carbon pre-filter that has a non-removable sheet. The baking soda, charcoal or carbon ingredient will be damage if is soaked with water. Even vacuuming we do not recommend as excessive force could damage the filter. Instead, ensure pre-filter is there to protect the carbon filter from dust accumulation.

We all frequently associate pre-filter will HVAC, furnace or ventilation system, it can also be found in the least expected places. From masks, respirators, speaker, and even in a laptop. The reason so many of these devices even bother fitting in a pre-filter is to reduce the number of dust from inflowing into the devices.
