Air Purifiers: Why They were Made and How Useful They Are

People spend 90% of their time indoors. Unfortunately, indoor air is not 100% clean. In fact, most of the lung-related problems are attributed to the uncleanliness of their indoor air.

This is why indoor Air Purifiers are invented – to help people be secure that their indoor air is clean.


Air purifiers are electronic devices or appliances that you can run in your home. They have the ability to remove contaminants from the air. If you’re ever wondering what the true benefits of having air purifiers are, you’ve come to the right place.

Generally, air purifiers can take care of contaminants like pollen, dust, pet dander, and cigarette smoke. These devices are highly suggested as being a great way to improve the air for people especially at risk of being affected by these irritants such as people with allergies, asthma, or other breathing problems.

The Environmental Protection Agency (EPA) estimates that, on average, indoor air is two to five times more polluted than outdoor air. This includes common allergens like pollen, dust mites, pet dander, and mold spores but also exhaust emissions, smoke, VOCs, and other chemical vapors.


Understanding air purifiers entails the requirement of understanding HEPA. HEPA stands for High Efficiency Particulate Air. Back then, HEPA air purifiers are originally developed by the Atomic Energy Commission to capture radioactive dust particles. Nowadays, most HEPA air purifiers do not filter radioactive particles, but they can take care of common allergens like pollen, mold spores, dust, etc.

HEPA purifiers have been tested and confirmed to have the ability to remove air contaminants larger than 0.3 microns at a success rate of 99.9 percent. Air contaminants that are very likely to be larger than 0.3 microns include asbestos, pet dander, pollen, cigarette smoke, and certain kinds of dust. The main beneficiaries, therefore, of air purifiers are people who are susceptible to being affected by these irritants.


Many causes of breathing-related health problems can be managed with a good air purifier. For example, the cause of hay fever is pollen particles in the air in spring, which causes irritation to the eyes and may lead to an asthma attack in susceptible adults and children alike.

Mold spores, meanwhile, thrive in damp and humid areas, such as bathrooms, causing severe lung infections and breathing difficulties if inhaled. Similarly, dust mites live in the dust in your home and have been scientifically proven to cause skin allergies. All of these can be taken care of easily by a good whole house air purifier.

These machines are also important to those who have smokers in their house. Passive cigarette smoke inhalation has been scientifically proven to cause lung cancer in nonsmokers. As a result, it is important to have an adequate air cleaning system to eliminate lingering smoke.


There is nothing worse than stale cigarette smoke clinging to the walls and furnishings throughout the home for the family members who are non-smokers. There are air purifier models that specifically targets cigarette smoke, like the ones with HEPA filters removing 99.97% of pollutants with a pre-filter and charcoal filter to capture cigarette tar and smoke odors in the air.

Air purifiers come in many shapes and sizes, too. Smaller air purifiers that can simply be plugged into an outlet have also proved to be effective at removing irritants from the air. For example, a console sized air purifier that was placed in a room has shown to be effective at removing pollen and plant spores from the air in that room. Bigger ones like whole house purifiers, though they bring about larger electricity costs, can take care of most the space in your home.
