Which water filtration method is best?
While most of us expect our tap water to be 100% safe, the truth is aging water infrastructures and countless other factors can contribute to the presence of many unwanted contaminants. Home water purifiers like Aquamega are the best protection from viruses, bacteria, chemicals and metals like lead.
Water filters come in countless shapes and sizes, using physical barriers, chemical barriers, or a combination of both. There are four common methods for home purification, but they are not created equal.
Primary methods for filtering water
Filters using reverse osmosis are engineered to remove contaminants by using water pressure. As tap water passes through a membrane, harmful agents like lead, mercury and iron are flushed away. However, reverse osmosis will not remove some pesticides, solvents and metals such as chlorine and radon.
These filters use a chemical process that releases ions like sodium, and exchanges them for unwanted ions, like heavy metals. The result is softer water with a more pleasant taste, however Ion exchange also raises the sodium content of your water, and doesn't provide a completely pure taste.
Most contaminants have a boiling point higher than water, so they’re left behind after the water turns to steam. The steam is then collected and condensed back into water. Unfortunately, distillation also removes beneficial natural minerals from water in the process.
Charcoal is a very porous form of carbon, so it has a large internal surface area to trap all kinds of contaminants. Activated carbon can remove smaller impurities that physical filters can’t catch. It functions as a magnet for compounds like lead, pesticides, and VOCs, trapping them internally as the water passes through. Chemicals like chlorine are reduced through a natural reaction when water first contacts the carbon.
Aquamega water purifiers use sediment and activated carbon filters, effectively making your tap water purer and more delicious. Home filtration with an NSF certified filter is the only way to know that the water you’re drinking has removed as many potentially contaminants as possible. Installation is easy, and can greatly improve the health and well-being of everyone in your home.
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.

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.
