House Dust are fine particles that typically made up of dead skin/ skin cell, pollen, hair, textile fibers, soil minerals, cosmic dust, and various indoor materials. Depending on how small a dust particle is, dust can stay airborne for up to 5 days. On average home produces 4 pounds of dust every month (around the weight of an ultrabook laptop). Most people are allergic to dust mites rather than dust itself.

What can an air purifier do: Not only it can remove airborne dust via its pre-filter/ HEPA filter, the filtration will also capture all irritants that travel along with dust. This includes dead skin, animal fur, dander, decomposing insects, dust mites, food debris, hair, fabric fiber and many more.

There are four major types of germs: bacteria, viruses, fungi, and protozoa. Germs are often spread through the air via sneezing, coughing, rubbing eyes, or even simple handshake. Studies have shown most germs/ flu viruses can stay active up to 24 hours while specific cold viruses can survive in an indoor environment for up to 7 days. Children or a person with a weakened immune system are more vulnerable to common cold, cough, sore throat, and other common illnesses caused by germs.
