Honoring World Environment Day

June 5 is World Environment Day (WED)

Not to be confused with Earth Day, WED was established by the UN General Assembly. Since 1974, it’s been celebrated every year on June 5, and is the United Nations' primary program to encourage awareness and action for the protection of our planet. The event engages governments and businesses to focus their efforts on serious environmental issues. Each year, a different host country is chosen for the official celebration.

Read below for easy ways you can honor this day, and do your part to help protect and heal the planet.

Skip the plastic

To help divert plastic waste from the world’s oceans, get a reusable water bottle for each member of your family. The average American spends $266 on single-use, disposable water bottles every year, so you’ll be saving money while supporting the environment. Paired with an at-home water purifier like Aquamega, you can enjoy an endless amount of pure water from your tap.

Save water

Did you know producing a single roll of toilet paper can waste 37 gallons of water? Also, a single flush can send more than 7 gallons of water into the sewer system. It’s time to upgrade your toilet habits. New eco-friendly models of toilets can use as little as 1 gallon per flush, and using a smart toilet seat like Bidetmega only uses about 1/8 of a gallon of water per cleansing. With less paper waste, less mess, and better hygiene, it’s a win-win-win.

Breathe clean air

To keep up the health of the planet, we must watch our own health, too. An estimated 7 million premature deaths occur every year due to air pollution. While industries and scientists attempt to alleviate harmful pollutants in industrial, agricultural and urban areas, you can keep your home more secure with an air purifier like Airmega with Eco Mode. With a True HEPA filter, Airmega captures and reduces up to 99.97 percent of particles 0.3 microns in the air, including pollen, pollutants and other allergens.

The world belongs to all of us

Remember, every action we take can either support or harm our own environment. Since our planet is the only home we have, it’s up to all of us to do our part and make it a sustainable, healthy place today, and for generations ahead of us.


1Coway air purifiers has 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.
