Improving air quality at home article from healthline link image

“Bringing an air purifier into your home is one effective way to keep your air cleaner. You may want to opt for an air purifier with a high efficiency particulate absorbing (HEPA) filter, since these tend to do the best job of removing harmful particles from the air.” 


WHY IAQ (Indoor Air Quality)

Poor IAQ May Affect Cognition, Productivity

“Overall, the study suggests that poor indoor air quality affects health and productivity significantly more than we previously understood.”

September 2021, Harvard, T.H. Chan School of Public Health

Regular Use of Common Disinfectants

“In a study of 73,262 US female nurses, exposure to cleaning products and disinfectants was significantly associated with a 25% to 38% increased risk of developing chronic obstructive pulmonary disease independent of asthma and smoking.”

Adverse Health Effects

“Americans, on average, spend 90% of their time indoors, where the concentrations of some pollutants are often 2 to 5 times higher than typical outdoor concentrations.”

Health effects can include:

  • Irritation of the eyes, nose, throat.
  • Headaches, dizziness, fatigue.
  • Respiratory diseases, heart disease, and cancer.

Indoor Air Pollutants

  • VOCs (Volatile Organic Compounds) – gasses emitted by household items (especially new homes – paint, cleaners, insecticides. furniture, appliances …
  • Carbon Monoxide – short term exposure can be lethal
  • Episodes of Legionnaires’ disease
  • Dust mites, mold, pet dander, particulate matter, and others – are “asthma triggers

Photocatalytic Oxidation

Uses UV light to turn moisture into a cleansing vapor, destroying microbes and rendering contaminants harmless.

How nanostrike works

Bipolar Ionization

Electrical charges create ions that draw particulates together in a clump, causing them to fall from the breathing space.
