How much water should I drink every day?

Do you ever suddenly feel a little dizzy? Or get a headache that you can’t explain? These symptoms, along with others like low energy or muscle cramps, could be telling you to drink more water.


Often people overlook the symptoms of dehydration because they’re subtle and they can be similar to other conditions. Yet the solution to these issues may be as close as the kitchen faucet.


The 8 x 8 rule, the idea that people should drink 8, 8-ounce glasses of water a day, has become common thinking largely because it’s easy to remember. And it’s a fine guideline to follow. However, it’s also important to think about water intake in the context of other lifestyle habits.


For instance:

• How much do you exercise? If you sweat a lot during workouts, you’ll need to drink more water.

• Do you live in a hot climate? If it’s hot and humid out, be sure to increase your fluid intake.

• Speaking of fluids, coffee counts! Contrary to popular belief, there’s no evidence that moderate coffee drinking dehydrates the body.

• Do you often feel hungry? Sometimes we confuse the feeling of thirst for hunger. Especially if you’re looking to reduce your calories, try drinking water before giving in to food cravings.


With these variations in mind, a good online hydration calculator, like this one from CamelBak, can help determine your best daily hydration level. It asks about everything, from gender to outdoor conditions, to arrive at the right water intake for each individual.


Our bodies are made up of 60% water and when we’re hydrated, we help our bodies stay in top working condition. The Coway Aquamega water purifier helps support healthy and active lifestyles by providing an unlimited water supply, right at home. The system filters up to 99.9% of contaminants, including lead. Now that’s a reason to raise a glass.


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.
