3 Top-Rated Air Purifiers for Construction Site (Best Picks & Handy Tips)


The air quality on a construction site, where buildings are being built, renovated, or demolished, is undeniably much worse than in a non-construction area.

During construction activities, harmful air pollutants such as silica dust and chemical odors are always present in high concentrations.

If you work on a construction site or live nearby, you should take precautions to avoid inhaling these harmful air pollutants.

In this blog, you will find the 3 top-rated air purifiers for construction site, and useful tips to remove the dust and chemical smells from construction site.

1. Air Pollution from Construction Sites

You may find metal, wood, concrete, sand, gypsum, plastics, steel, masonry, stone, and other building materials on a construction site. These building materials produce various types of air pollutants during construction activities.

Dust pollution is the most common phenomenon in construction areas. Below are the top 3 sources of dust pollution from construction activities.

Silica dust: Generated by the mixing work on materials such as sandstone, mortar, and concrete.

Wood dust: Produced by sawing and sanding woods like plywood, hardwoods, and softwoods.

Lime Dust: Produced by sawing and sanding marble, as well as working on gypsum, limestone, and dolomite.

World Health Organization data show that construction dust particles range from 1 to 100 microns in size. Apart from the visible particles (particles ≥ 25 microns) in the air, the majority of the dust mentioned above is invisible and classified as PM10 (particles ≤ 10 microns).

Additionally, diesel exhaust from vehicles, diesel generators, and other heavy equipment cause PM 2.5 (particles ≤ 2.5 microns). The wind-borne dust can remain in the air for days or even weeks.

Construction projects also cause gas pollution. The use of chemicals, such as glue, paint, plastics, cleaners, and oils, will evaporate below toxic gases.

  • VOCs (Volatile Organic Compounds)
  • Carbon Dioxide
  • Carbon Monoxide
  • Hydrocarbons
  • Nitrogen Oxides

2. Health Impact of Construction Dust and Gases

According to ELCOSH, a construction blog, more than 500 construction workers die from lung cancer in the United States each year.

If you work in a construction area or live nearby, you are at risk of inhaling toxic dust and gases. The harmful air pollutants you breathe in will cause the following health issues.

  • Coughs
  • Asthma
  • Dizziness
  • Headache
  • Allergic Skin
  • Lung Cancer
  • Shortness of Breath
  • Irritation of the Eyes, Nose, and Throat
  • Cardiovascular and Respiratory Diseases

As you spend more time working or living near construction sites, your symptoms will worsen. Therefore, you should take proper precautions to avoid inhaling toxic construction dust and gases.

3. Best Construction Site Air Cleaners

4. Tips for Reducing Construction Dust and Smell

Use green products. When you purchase the building materials such as paints, glues, and oils, please take a look at the label of the products to see if it is VOC-free, or odor-free. Using silica-free materials can reduce the risk of exposure to construction dust as well.

Wear protective gear. When working on a construction site, always wear PPE (Personal Protective Equipment), such as a medical-grade mask, to avoid inhaling harsh particles and chemical odors.

Use water to dampen the dust clouds. If you notice dust clouds, you can spray the appropriate amount of water to reduce them.

Keep the construction site clean every day. Winds can easily blow the dust off the ground. In general, the more dust it is on the ground, the higher the level of dust in the air. Thus, you should sweep and vacuum the construction area daily to keep it as clean as possible.

Do dust-generating work at a well-contained site. To reduce the spread of dust pollution, use plastic barriers or zipwalls to keep dust contained in one area.
