Air Quality

This section is dedicated to the scientific exploration of indoor air quality (IAQ). The goal is to move beyond marketing claims and build a foundational understanding of airborne pollutants, their health effects, and the technologies designed to mitigate them. By relying on evidence-based research from reputable organizations like the EPA and WHO, we will identify and compare effective solutions for creating a healthier indoor environment.

Items List

Below is the categorized list of items I plan to research. Each item will eventually link to its own detailed analysis.

Core Environmental Control

  1. Air Purifier
    • Devices designed to remove contaminants from the air, such as dust, pollen, pet dander, mold spores, and VOCs.
  2. Humidifier
    • Devices that increase moisture (humidity) in a room or entire building.
  3. Dehumidifier
    • Devices that reduce the level of humidity in the air.
  4. Air Quality Monitor
    • Devices that measure the levels of common air pollutants in real-time.

Keywords for Search & Discovery

This section helps guide the research process. Combine keywords from different categories to perform targeted searches.

  • Core Nouns (Item Types): Air Purifier, Humidifier, Dehumidifier, IAQ Sensor, HEPA Filter
  • Pollutants & Particulates: Particulate Matter, PM2.5, PM10, VOCs, Formaldehyde, Mold Spores, Pollen, Pet Dander, Radon
  • Metrics & Technologies: CADR (Clean Air Delivery Rate), ACH (Air Changes per Hour), MERV, HEPA, Activated Carbon, UV-C, AQI (Air Quality Index)
  • Health & Research Terms: Allergies, Asthma, Sick Building Syndrome, Peer-reviewed study, EPA, WHO, Toxicology

Key Concepts for Air Quality

This section covers key concepts and terminology that apply across the entire subtopic.

  • Particulate Matter (PM2.5 & PM10): PM refers to a mixture of solid particles and liquid droplets found in the air. PM2.5 are fine inhalable particles, with diameters that are generally 2.5 micrometers and smaller. PM10 are inhalable particles, with diameters that are generally 10 micrometers and smaller. PM2.5 is a greater health risk as its small size allows it to travel deep into the respiratory tract.
  • Volatile Organic Compounds (VOCs): VOCs are gases emitted from certain solids or liquids. They include a variety of chemicals, some of which may have short- and long-term adverse health effects. Sources include paints, cleaning supplies, pesticides, and building materials.
  • Clean Air Delivery Rate (CADR): A metric developed by the Association of Home Appliance Manufacturers (AHAM) that indicates the volume of filtered air an air purifier can deliver. It is measured in cubic feet per minute (CFM) and has separate scores for smoke, pollen, and dust.
  • HEPA (High-Efficiency Particulate Air): A standard for air filters that, to qualify, must remove at least 99.97% of airborne particles 0.3 micrometers (µm) in diameter.
