Cyst is a type of microbe that grows in water and can be reduced by up to 99.9 percent through purification.


Volatile organic chemicals, or VOCs, caused by industrial runoff can be reduced by 99.8 percent.

Chlorine and Chloramine

What's Inside?

Coway Aquamega 100’s multistage, triple-filtration system uses a powerful combination of sediment, pre-carbon and post-carbon filters. The unit comes with one faucet-mounted diverter, three faucet adapters, one T-valve, 6.5 ft. of tubing and two L-fittings.

Stage 1

In the first stage of purification, water passes through the sediment filter (A-1), which reduces sand, rust, turbidity and cyst. These are the larger particles that may be found in tap water.

Stage 2

The second stage uses a pre-carbon filter (A-2) to reduce odor as well as chemicals including chlorine, chloramine and VOCs. This filter also treats any remaining sand, rust, turbidity or cyst.

Stage 3

The third and final stage of purification uses a post-carbon filter (A-3), which reduces mercury and lead, as well as remaining sand, rust, turbidity, cyst, chlorine, chloramine and VOCs.
