Healthy Air Everywhere for Everyone.
"People spend up to 90% of their time indoors, yet indoor air can be 2 to 5 times more polluted than outdoor air — often leading to symptoms like headaches, fatigue, and reduced cognitive performance, with studies showing poor indoor air quality can decrease office productivity by 6-9%."
— U.S. EPA and European Ventilation Industry Association (EVIA), supported by field research on ventilation and pollutant levels.
Why Prioritize Healthy Indoor Air Certification?
Indoor air pollution ranks among the top environmental health threats globally, often more dangerous than outdoor pollution because we spend the majority of our time inside.
Poor indoor air quality can contribute to respiratory issues, allergies, fatigue, and long-term health problems—while also impacting sensitive electronics, equipment, and valuable items through dust, humidity, and contaminants.
We have certificates for everyone and everyplace, including equipment.

Understanding PM2.5 and PM10 Particulate Matter
Particulate matter (PM) is a complex mixture of tiny solid particles and liquid droplets in the air, categorized by size. PM10 (coarse particles) includes all particles with a diameter of 10 micrometers (µm) or smaller, which can be inhaled into the upper respiratory tract. PM2.5 (fine particles) is a subset of PM10, covering particles 2.5 µm or smaller, which can penetrate deep into the lungs and even the bloodstream.
These particles come from various natural and man-made sources, either directly emitted (primary) or formed through atmospheric reactions (secondary).
Their composition includes hundreds of chemicals, varying by location and source.
Below, I've compiled actual lists of different items (specific components, substances, and particle types) that fall under each category, based on reliable sources like the EPA, California Air Resources Board (CARB), and scientific studies.
've distinguished them where possible, noting that PM2.5 components are fully included in PM10. Lists are grouped by type (e.g., chemical compounds, elements) for clarity, with examples of sources.
Items Under PM10 (Coarse Particles: ≤10 µm, Including Both Fine and Coarse Fractions)
PM10 encompasses larger particles (2.5–10 µm, often from mechanical processes) plus all PM2.5. Common components include:
- Inorganic Ions and Compounds: Sulfates (e.g., ammonium sulfate ((NH₄)₂SO₄)), nitrates, ammonia, sodium chloride (sea salt), carbonates/bicarbonates.
- Metallic Compounds and Elements: Aluminum (Al), silicon (Si), potassium (K), calcium (Ca), titanium (Ti), iron (Fe), manganese (Mn), zinc (Zn), copper (Cu), vanadium (V), nickel (Ni), bromine (Br), barium (Ba), lead (Pb).
- Carbon-Based Particles: Elemental carbon (black carbon/soot), organic carbon (OC, including organic compounds from vegetation or combustion).
- Crustal and Mineral Materials: Mineral dust, dirt, soil particles, metal oxides, geological matter (e.g., silicon, aluminum from earth’s crust).
- Biological and Organic Fragments: Pollen, mold spores, fragments of bacteria, biological aerosols, small liquid droplets (e.g., water-based).
- Other Substances: Chlorine (Cl), sulfur (S), trace metals, diesel particulate matter (DPM, mostly <1 µm but part of the mix), smoke particles, ash.
Examples of Sources for PM10:
- Natural: Wind-blown dust from open lands, pollen from plants, sea salt from ocean spray, wildfires, trees/vegetation (emitting organic compounds), fragments of bacteria.
- Man-Made (Primary): Dust from construction sites, unpaved roads, landfills, agriculture, fields, industrial processes (e.g., bulk material handling, minerals processing), brush/waste burning, road abrasion, brake/tire wear.
- Man-Made (Secondary): Atmospheric reactions of gases like sulfur dioxide (SO₂), nitrogen oxides (NOₓ), and volatile organic compounds (VOCs) from power plants, industries, and automobiles.
Items Under PM2.5 (Fine Particles: ≤2.5 µm)
These are finer, often combustion-derived particles that make up about two-thirds of PM10 mass in many areas. They include:
- Inorganic Ions and Compounds: Sulfates (e.g., ammonium sulfate ((NH₄)₂SO₄), 44% of mass in some studies), nitrates (including ammonium nitrate), ammonia.
- Metallic Compounds and Elements: Vanadium (V, primarily), nickel (Ni, primarily), lead (Pb, exclusive), zinc (Zn), copper (Cu), iron (Fe), titanium (Ti), bromine (Br), barium (Ba), aluminum (Al), silicon (Si), potassium (K), calcium (Ca), sulfur (S, exclusive as sulfate tracer).
- Carbon-Based Particles: Elemental carbon (black carbon/soot, exclusive, 7% of mass), organic carbon (OC, 40% of mass, including tarballs and VOC-derived aerosols).
- Crustal and Mineral Materials: Metal oxides (5% of mass), trace crustal elements (minor, e.g., from road dust).
- Biological and Organic Fragments: Organic compounds from vegetation, small smoke particles.
- Other Substances: Sea salt (minor, 2%), diesel particulate matter (DPM, >90% <1 µm), unknown/unmeasured (e.g., trace organics, crystalline water).
Examples of Sources for PM2.5:
- Natural: Trees/vegetation (organic compounds), wildfires (smoke and ash).
- Man-Made (Primary): Combustion of gasoline, oil, diesel fuel, or wood (e.g., vehicle exhaust, wood burning for heating), motor vehicles (emissions, brake/tire wear), oil combustion (e.g., power plants, ships, home heating).
- Man-Made (Secondary): Regional pollution from atmospheric reactions of SO₂, NOₓ, and VOCs (e.g., from industries, automobiles, forming sulfates and nitrates).
These lists are not exhaustive but cover the most common items identified in air quality research. Compositions can vary by region (e.g., more sea salt near coasts, more dust in arid areas). For your healthy air business, focusing on HEPA filters can effectively capture these particles, especially PM2.5 from indoor sources like cooking or candles. If you need more region-specific details (e.g., UK-focused) or visuals, let me know!
