ICYMI: Early allergies, dust mite treatment, and more

The early spring that seemed to have sprung in February led to some unintended consequences. Meanwhile dust has found a foe in a new pharmaceutical product and low vitamin E in mothers has been linked to increased cases of asthma in children. Finally, Harvard gets closer to proving that green buildings are better in more ways than you may think.

Early Seasonal Allergies

If you live in the eastern United States, you have likely been enjoying the spring-weather. So have the plants and trees in the region, which has triggered increased reports of allergies. High concentrations of tree pollen have been reported in cities along the Atlantic coastal states leading to an early allergy season for some.

New Dust Mite Treatment

A new under-the-tongue tablet called Odactra has been approved for the treatment of dust mite allergies. The tablet is taken once a day ongoing and dissolves under the tongue. Odactra falls into the category of allergen immunotherapy, which exposes patients to allergens in regulated doses to get the immune system to respond more aggressively. However, the drug takes eight to 14 weeks to show results and has side effects.

Asthma and Vitamin E

Asthma may be one of the most mysterious autoimmune diseases with links and correlations being proposed regularly. Most recently, Vanderbilt, and Northwestern University researchers have found a link between low maternal vitamin E levels and increased incidence of childhood asthma. Other suggested causes of asthma include smoking during pregnancy, C-section births, excessive hygiene, and genetic factors.

Green Buildings Win

A recent Harvard public health study suggests that high-performing green-certified buildings improve employee performance. The study took place during a two-week assessment that measured cognitive function and found that proper daytime building lighting positively affected circadian rhythms and nighttime sleep quality. One of the key buildings used in the study, called Blackstone, implemented an indoor air quality plan during construction that minimized dust, used nontoxic fabrics, paints, and decorative products, and established an ongoing green cleaning program.


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.
→ Tested with Airmega Aim, 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.
