However, choosing the right one can take time due to the many options available. This comprehensive review will explore the different types of air purifiers, highlighting their unique features and benefits to help you make an informed decision.
Mechanical Air Purifiers: HEPA Filters
High-Efficiency Particulate Air (HEPA) filters are the most common and widely recognised type of air purifier. They force air through a fine mesh filter, trapping particles such as dust, pollen, mould spores, and pet dander. HEPA filters are proven to capture at least 99.97% of particles 0.3 microns in size or larger, making them highly effective in improving indoor air quality.
Activated Carbon Filters: Tackling Odors and Chemicals
Activated carbon filters utilise a porous form of carbon to adsorb gases, odours, and chemicals, such as volatile organic compounds (VOCs), smoke, and fumes. They are often combined with HEPA filters to provide comprehensive air filtration, tackling particulate matter and gaseous pollutants.
Electronic Air Purifiers: Ionic and Electrostatic
Ionic air purifiers, also known as ionisers, emit negatively charged ions into the air. These ions attach to positively charged particles, causing them to become too heavy to remain airborne and fall onto surfaces or attach to a collection plate within the purifier. Electrostatic air purifiers work similarly but use electrostatic precipitators to collect the charged particles. While these air purifiers are typically quiet and energy-efficient, they may produce trace amounts of ozone as a byproduct, which can irritate some individuals.
Ultraviolet Germicidal Irradiation (UVGI) Air Purifiers
UVGI air purifiers use ultraviolet (UV) light to kill or inactivate microorganisms such as bacteria, viruses, and mould spores. The effectiveness of these purifiers depends on the intensity and duration of UV exposure. UVGI air purifiers are usually combined with other filtration methods, like HEPA filters or activated carbon, to provide a more comprehensive air-cleaning solution.
Photocatalytic Oxidation (PCO) Air Purifiers
Photocatalytic oxidation (PCO) air purifiers use UV light to activate a catalyst, typically titanium dioxide, which breaks down pollutants into harmless substances like water and carbon dioxide. PCO air purifiers can be effective against VOCs, bacteria, and viruses. However, they may produce small amounts of ozone and require adequate airflow to ensure pollutants reach the catalyst.
Ozone Generators: A Word of Caution
Ozone generators intentionally produce ozone to break down pollutants and neutralise odours. However, ozone can harm human health, causing respiratory issues and exacerbating pre-existing conditions like asthma. The Environmental Protection Agency (EPA) does not recommend using ozone generators for residential use due to the risks associated with ozone exposure.
