50 Years of Earth Day: 6 Ways to Fight Climate Change from Home

Earth Day is about all of us

The 50th anniversary of Earth Day is on April 22, and the theme is climate action. Both opportunities and obstacles to action around climate change have revealed to us that the time is now to take charge and protect this planet—our only home.

Since our #healthyobsession is with home health, any risk to our world’s habitability is reason enough to wake up and act. Climate change does not discriminate. It affects life’s essentials: the air we breathe and the water we use. Luckily, there are some positive actions you can take from the comfort of your home.

1. Use sweaters and blankets

During cooler months, set your thermostat as low as possible. Even a few degrees can make a huge difference over time, not to mention energy cost savings. Keeping sweaters and blankets in convenient places around the home will help build better habits. You can also take advantage of heat from the sun by opening curtains on your sun-facing windows, and be sure to close them at night. If you have drafty windows, tight-fitting, insulating drapes can have a big impact.

2. Turn down your water heater

It’s easy to turn down the temperature of your water heater to the warm setting (about 120°F). You can save energy and as a bonus, avoid scalding your hands.

3. Keep it cool with the laundry

You may be surprised to know that 90% of washing machine energy typically goes towards heating water. A good rule of thumb is to keep it on cold, and don’t touch the dial.

4.Upgrade appliances and use Eco Mode when available

Upgrading appliances can help conserve energy in your home. Many modern appliances naturally conserve energy, or feature an efficient Eco Mode, like on the Airmega 400.

5. Filter your own water

Sadly, we’re up to 1 million plastic bottles used per minute, and 91% of those go unrecycled. Filtering water at home and bringing a reusable bottle wherever you go can really make a statement, and reduce the 60 million bottles thrown in landfills every day.

6. Use a bidet

Not only is a bidet an excellent cost-cutting measure, it’s better for the environment. 15 million trees are cut down to supply the USA with toilet paper annually. It’s time to change the curve. Besides cutting back on toilet paper, Bidets have several cost and health benefits.

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.
