Coway Aquamega Filters Being Tested in Lab

Why are water purifiers so important?

What’s in your water?

Unfiltered water harbors all kinds of particles and contaminants, from heavy metals and toxic chemicals to microorganisms that can cause health problems. The quality of your water depends both on its source and the way it’s delivered to your home’s faucets. 

What is lead poisoning?

Children exposed to lead can suffer from behavior and learning problems, lower IQ and hyperactivity, slowed growth, hearing problems and anemia. In adults, lead poisoning can affect pregnancy, blood pressure and kidney health and cause reproductive issues in both men and women. 

Lead can enter drinking water when plumbing materials that contain lead corrode, especially where the water has high acidity or low mineral content that corrodes pipes and fixtures. According to the EPA, the most common lead sources in drinking water are lead pipes, faucets, and fixtures. Luckily. human skin can’t absorb lead from water, so you only need to worry about the water you ingest. If you’re drinking purified water from your Aquamega 200C, you have nothing to worry about since its two-stage carbon block filters remove 99.9% of lead and cysts.

What are cysts in unfiltered water?

Cysts are parasites found in the intestinal tracts of animals that can infect surface water and groundwater under the influence of surface water when the animals defecate. The parasites spread to humans when they ingest them in unfiltered water, and infection can spread via contaminated surfaces, food and contact with other infected people. Giardiasis is a common illness caused by a cyst called Giardia that can cause diarrhea and stomach cramps. 

What are PFCs?

Perfluorinated Compounds, also known as PFCs, are chemicals used in products that resist or repel oil, grease, and water-based liquids, often marketed as stain-resistant or non-stick fabrics or surfaces. According to the CDC, when ingested in large amounts, PFCs can affect growth and development, reproduction, and injure the liver. 

What are VOCs?

Volatile organic compounds, also known as VOCs, are a subcategory of organic compounds with a high vapor pressure at room temperature. They are highly flammable, and a few common examples include butane, propane, acetone and pesticides. Excess ingestion of VOCs can cause damage to the brain, nerves, kidneys and liver. Excess exposure can also cause cancer. 

What does the Aquamega 200C 2-Stage Filter remove? 

The Carbon Block filter reduces chlorine, chloramine and other odor-causing substances. It also removes lead, mercury, cysts, BPA, and volatile organic compounds (VOCs). The Sediment filter removes infusible particles such as sand, rust, cysts, and turbidity.

Proven to provide healthier water

Aquamega’s 200C filters are tested and certified by the Water Quality Association. They have been tested and certified to remove 99.9% of lead and cysts from water in addition to PFCs* and VOCs*. If you are interested in Aquamega 200C for your home or business, learn more at



*Internal test data 


1Coway air purifiers have been proven to trap dust, pollen, dander, viruses and bacteria in the air based on KCL (Korea Conformity Laboratories) testing.They have been tested in a 30㎥ size chamber according to the Korea Air Cleaning Association standard (SPS-KACA 002-132:2022 Modified) to measure the 0.01㎛ size of particle removal rate. It was tested on maximum airflow speed in normal room temperature and humidity conditions. The performance may vary in the actual living environment of customers.
→ Tested with Airmega Aim, 100, 150, 160, AP-1216L, AP-1512HH, AP-1512HHS, 200M, Icon, IconS, 230, 240, 250, 250 Art, 250S, 300, 300S, 400, 400S, ProX

299.97% of viruses, bacteria, fungi and pollen were verified to be removed from the air for Coway air purifiers which have Green True HEPA™ filter applied based on the Japan Food Research Laboratories(JFRL) testing according to JEM 1467 standard.
→ Tested with Coway Airmega AP-1512HH, AP-1512HHS, 250, 250 Art, 250S, 300, 300S, 400, 400S
→ All tested by JFRL and received above result within below time.

All tested by JFRL and received above result within below time.

- Virus: Tested with Escherichia coli phage ΦX174 NBRC 103405, 60 minutes
- Bacteria: Tested with Staphylococcus epidermidis NBRC 12993, 60 minutes

3Aerosol test conducted in a Biosafety level 3 laboratory with two Coway air purifier models, Coway Airmega 250 and 400 for removal of SARS-CoV-2 Aerosol by US based MRI Global, a not-for-profit laboratory and partner of US Department of Defense. The test was conducted in a 13.1ft3 chamber. Virus was aerosolized for 15 minutes and the product was turned on high for 2 minutes. Result showed each product effectively removed over 99.98% of the SARS-CoV-2 in 2 minutes. This is a result from a laboratory experiment condition and result may vary in different conditions. This result does not imply it kills SARS-CoV-2 or prevents the transmission of Covid-19. Coway Airmega 250S and 400S are identical to the tested models and has equal performance with an additional mobile connectivity function.

4The concentration of ammonia, acetaldehyde and acetic acid were proven to be removed within 30 minutes by FCG Research Institute, Inc. Human Life Science Lab. It is not a demonstration result in the actual use space. Not all odors and gases may be supported. → Tested with Coway Airmega 150, 160, AP-1512HH, AP-1512HHS, 400, 400S

5The coverage area of the air purifier is based on an area where the air cleaner can make two air changes per hour (ACPH). An air change per hour translates to how many times an air purifier can clean an area, assuming the height of a ceiling to be 8 ft, in one hour. Therefore ** means two air changes per hour means that the cleaner can clean the area once every 30 minutes and * means air changes per hour means that the air purifier can clean the area once every 60 minutes.
