Air cleaners improve indoor air quality by removing contaminants from the air through various mechanisms. They typically use a combination of filters, fans, and sometimes additional technologies to capture and neutralize pollutants. 1. **Filtration**: The most common method involves mechanical filters, such as High-Efficiency Particulate Air (HEPA) filters, which trap particles like dust, pollen, and pet dander. HEPA filters can capture particles as small as 0.3 microns with 99.97% efficiency. Some air cleaners also use activated carbon filters to adsorb odors and volatile organic compounds (VOCs). 2. **Electrostatic Precipitation**: This method uses electrically charged plates to attract and capture particles. As air passes through the cleaner, particles receive an electrical charge and are drawn to oppositely charged plates, effectively removing them from the air. 3. **Ionization**: Ionizers release charged ions into the air, which attach to airborne particles, causing them to clump together and fall out of the air or be captured by a filter. This method can reduce particulate matter but may produce ozone as a byproduct, which can be harmful in high concentrations. 4. **Ultraviolet (UV) Light**: Some air cleaners incorporate UV light to kill or deactivate microorganisms like bacteria, viruses, and mold spores. The UV light disrupts the DNA of these pathogens, rendering them harmless. 5. **Photocatalytic Oxidation (PCO)**: This technology uses UV light and a photocatalyst, such as titanium dioxide, to produce hydroxyl radicals that break down pollutants like VOCs and microorganisms into harmless substances. By employing these technologies, air cleaners can significantly reduce indoor air pollutants, leading to improved air quality and health benefits for occupants.

Portable air cleaners are standalone units designed to be moved easily from one room to another. They are typically compact, lightweight, and plug into a standard electrical outlet. These units are ideal for targeting specific areas or rooms, providing flexibility in usage. They often come with features like multiple fan speeds, timers, and air quality sensors. Portable air cleaners are generally more affordable and require less installation effort compared to wall-mount units. Wall-mount air cleaners, on the other hand, are fixed installations that are mounted on walls, often in a central location within a room or building. These units are designed to be more permanent solutions and are typically more powerful, capable of cleaning larger volumes of air. Wall-mount air cleaners are often used in commercial or industrial settings, but they can also be installed in homes. They may require professional installation and are usually connected to the building's electrical system. These units can be more aesthetically pleasing as they are integrated into the room's design and do not occupy floor space. In summary, the main differences lie in their mobility, installation, and capacity. Portable air cleaners offer flexibility and ease of use, making them suitable for smaller spaces or temporary needs. Wall-mount air cleaners provide a more permanent, powerful solution for larger areas, often requiring professional installation and offering a more integrated appearance.
