4 steps to getting better sleep during allergy season

Do allergies make you tired, or suffer at night?

If you or a loved one suffers from allergy symptoms, you can sneeze in your sleep, wake up congested, and your allergies may even get worse at night. You already know there's more to airborne contaminants than car exhaust and smoke. When invisible particles like mold spores, pollen, and pet dander are in your air, it can be tough to breathe clear and get a good night's rest. But before you turn to a nighttime allergy medicine, try these 4 effective steps to get a perfect night's rest. You may just unlock the best sleep of your life!

Step 1: Invest in anti-allergy bedding.

For many of us, allergies get worse at night. Dust, pollen, and dirt get into the mattress, and we are forced to sleep with a runny nose. Luckily, bedding with advanced, anti-allergy fabrics that you wash often can help you avoid worsening allergies while you’re trying to dream.

Step 2: Try keeping your pet out of bed.

If you have a pet, and you wake up congested, it may be the family dog or cat igniting those allergies. In addition to your pet’s dander, they may also be tracking pollen, dust mites and mold into your bedroom. For relief, try keeping them off the bed, or move them out of the bedroom.

Step 3: Take a shower before sleeping.

Pollen, mold and dander can stick to your body and hair, so showering ensures a bed that’s free of the contaminants you don’t want next to you. It’s one of the best ways to avoid waking up with a stuffy nose.

Step 4: Add an Airmega to the bedroom.

An air purifier like Coway Airmega, which effectively rids the air of these nano-particles, can be a life-changing upgrade. You can breathe clearer at night, and allergies won’t make you sleepy anymore. The Airmega 150 is an 18-inch purifier with an impressive 214 square feet of effective coverage, and the slightly larger AP-1512HH/S has the same effectiveness in rooms up to 361 square feet. These Coway air purifiers efficiently filter various harmful sources and removes 99.999%* of nano-sized particulate matter down to 0.01 micrometers, which is smaller than most viruses and bacteria.

Here’s what a customer thought after buying her Airmega: “The best air filter. I’ve tried them all as I tend to suffer from allergy asthma. I have a pug who sheds a lot and ever since we switched air filters to this one I have had zero issues. Love it so much we bought one for every room. #highlyrecommended” – Jessica on IG.

*Coway air purifiers have been tested according to the Korea Air Cleaning Association standard on a particle size of below 0.01㎛ and on maximum fan speed in normal room temperature and humidity conditions. According to Airmega 250's test report, 99.999% of 0.01㎛ particles are removed within 12 minutes. (Tested with Airmega AP-1216L, AP-1512HH, 150, 300, 250, 400)

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.
