Teaching kids about clean drinking water

Children are natural explorers. Adults often take things for granted, like daily drinking water, that children are excited to discover. With this in mind, the water filter and other learning activities presented here will spark kids’ curiosity–or maybe even inspire a lifetime of learning about H2O. After all, many of the water researchers and experts at Coway were once kids, too, with a thirst for knowledge.


How do water filters work?

Discover how water filters work with this quick craft. To start, gather these materials: a two liter soda bottle (cut in half), napkins or paper towels, gravel, sand and dirty water. Then place the top half of the plastic bottle, upside-down, into the bottom half. The top half will create a funnel for the water, and the bottom half will collect it. (To see an example, check out this video.)


Now, layer the filtering materials in the top half: first, the napkin or paper towel; second, the gravel; last, the sand. Once all the pieces are in place, from the top of the opened end, pour the dirty water down into the filtered part. Watch as clean water slowly accumulates at the bottom of the filter.


Tour your local public water facility

Big concepts--like supplying water to everyone in your hometown--become real when kids get to see the work first-hand. One of the best ways to do this is by touring your local public water facility.


The city of Houston, Texas, for example, offers a range of school tour topics to teach kids about water. Students can explore the water cycle, water quality and treatment, or water conservation, for example. Contact your local water authority to find out what learning experiences they offer for kids.


Create a water festival in your community

Thirty years ago, educators at the Groundwater Foundation held the first Children’s Groundwater Festival in Nebraska. The event has since inspired similar festivals around the world, including in places as far away as India and Australia. Each festival features games and workshops geared towards fourth and fifth graders. The foundation also offers guides to help groups develop a new festival for their community.


Activities like these give kids an appreciation for their drinking water. With the Coway Aquamega 100 triple-filtration system, children and parents alike can enjoy drinking fresh, clean, great tasting water right at 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.
→ 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.

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.
