Is Your Heating System Hurting You?

One of the best things about winter is getting cozy after a day outside breathing in all the cold, fresh air. Part of the ritual involves comfy clothes, a mug of something warm, and ample heating. But heating systems can release harmful particulates and gasses.

As a general rule, the older the heating system technology, the more the indoor air pollution. Wood smoke coming from fireplaces and wood burning stoves emits respirable particulates—those microscopic particles that float in the air and end up in your lungs. In addition to the particulate matter, wood combustion releases gasses including sulfur oxides, nitrogen oxides, carbon monoxide, and potentially carcinogenic compounds.

Health Risks Associated with Wood Smoke Inhalation

According to a leading study, prolonged inhalation of wood smoke, from an open fireplace or wood burning stove, contributes to bronchitis, lung disease, and hypertension; young children in homes with wood burning stoves are more likely to have moderate and severe chronic respiratory symptoms and a greater incidence of bronchitis, wheezing, coughing, and respiratory infections.

Modern Heating Methods and Their Drawbacks

More modern heating methods include kerosene heaters and oil and gas furnaces. While these do not tend to generate particulate matter, all produce harmful gasses. Older and unmaintained systems are, inevitably, less efficient than newer, maintained systems and create more of these gasses, as a result of incomplete burning. These gasses can then leak into your home.

Airmega: A Solution for Clean Indoor Air

As a HEPA air purification system, Airmega units are specifically designed to remove particulate matter from the air, including that emitted from wood burning. Plus, with an activated carbon filter, an Airmega unit can filter out gasses that are released during combustion—which allows you to get all snuggly on the sofa with both clear lungs and a clear mind.



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.
