  • Dust mitesThey are microscopic bugs that thrive in spaces with high humidity levels. dust mites are known to cause allergy symptoms.
  • AnimalsMost pets tend to stay indoors during the winter, if you are allergic to animal fur, saliva, urine or dander, your allergies will increase.

Most of these allergens thrive in spaces with high humidity levels. increased humidity indoors makes it easy for mold, mildew and dust mites to increase exponentially.

Minimize indoor allergens by :

  • investing in a dehumidifier this winter season? - A dehumidifier is an electric appliance that removes excess moisture from the air. Investing in a dehumidifier would keep the relative humidity below 50%. At that level mold, mildew and dust mites will not be able to survive. This reduces the number of allergens significantly. Ensure the dehumidifier you buy is fitted with HEPA air filter so as to easily remove any mold spore and another allergen in the air.
  • Minimize the amount of pet contact. Keep the pets away from the bedroom.
