Are your allergies due to mould?

The only consolation to seasonal allergies, presumably, is that we only have to deal with them during certain times of the year or on days with high pollen counts. But have you ever had allergy symptoms on days with a low pollen count? If so, you’ve probably lamented, “Why is this happening now?” In some cases, your runny nose or itchy eyes may actually be a reaction to mould.

As it turns out, one in twenty Americans have an allergy to mould. If you're one of these, you may find yourself having symptoms even when you don’t expect them. Because mould can be present indoors and out year-round, there is no “season” to a mould allergy. The following are symptoms that may indicate you have this allergy: sneezing, runny nose, congestion, and dry, scaly skin. Additionally, mould can act as a trigger for asthma sufferers, causing symptoms such as coughing, wheezing, or shortness of breath.

The best way to prevent symptoms from popping up is to identify where mould may be lurking in your daily life—and remove or avoid it. In your home, be on the lookout for dark, damp places. Common places are bathrooms, the kitchen, basements, and any compost piles you may have outside. If you find any small patches of mould , you can clean it with various DIY solutions made from household chemicals. However, for large areas of mould it’s best to contact a professional for removal, especially if you have an allergy.

You can also deploy some of the following tactics to prevent mould from growing in the first place. Always shower with the exhaust fan on or a window open to prevent moisture buildup in the bathroom. Check the drip pans and vents for water in appliances like your refridgerator, air conditioner, and humidifier and clean them out frequently. Give your storage space an update by moving your belongings to containers that are both air-tight and waterproof—to help keep mould out of your home. If you see any leaks in your home, be sure to fix them right away so the mould doesn’t have a place to grow. This also applies to making sure rainwater doesn’t pool close to the base of your home and leak into the foundation. And finally, you can use an air purifier with a HEPA filter to keep your air clear of mould and other particles that could be affecting your allergies. Airmega’s HEPA filter can remove up to 99.97% of the particles in your home.


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.
