1. HEPA Filters
2. Activated Carbon Filters
3. Photocatalytic Oxidation
4. Ionizers
5. Ozone Generators
6. Negative Ion Generators

Air purifiers vary in their capabilities and effectiveness regarding odour removal, making it essential to understand how each component contributes to eliminating unwanted smells.

1. HEPA Filters:
   HEPA filters trap airborne particles, such as dust and allergens, preventing them from circulating in the air. HEPA stands for High-Efficiency Particulate Air. These filters are very effective at capturing particles as small as 0.3 microns. However, HEPA filters alone do not remove gases and odours. Studies show that while HEPA filters improve overall air quality, they must work in conjunction with other technologies for odour removal (Fine et al., 2010).

2. Activated Carbon Filters:
   Activated carbon filters use a porous material that adsorbs a range of gases and odours. The activated carbon’s surface area allows it to trap various volatile organic compounds (VOCs) and cooking or pet smells. Research indicates that activated carbon can reduce odour concentrations significantly (Nazaroff, 2001). This makes them essential in air purifiers designed for odour removal.

3. Photocatalytic Oxidation:
   Photocatalytic oxidation involves a catalytic reaction activated by light. This process breaks down odour-causing compounds. Common catalysts include titanium dioxide. A study by Zhang et al. (2022) shows that photocatalytic oxidation can achieve nearly complete degradation of VOCs, making it a powerful tool for odour removal in air purifiers.

4. Ionizers:
   Ionizers emit negative ions that attach to airborne particles, causing them to clump together and fall out of the air. While ionizers can effectively reduce odours by clearing the air of particulates, some models produce ozone, which can be harmful at high concentrations. The EPA warns about ozone levels created by certain ionizers and recommends considering this when choosing an air purifier (EPA, 2021).

5. Ozone Generators:
   Ozone generators intentionally produce ozone to eliminate odours, mould, and bacteria. Ozone is a powerful oxidizing agent. However, high ozone levels can be harmful to human health. The FDA advises against using ozone as a cleaning agent for indoor air (FDA, 2020). Thus, while effective in certain situations, caution is advised with ozone generators.

6. Negative Ion Generators:
   Negative ion generators work similarly to ionizers by creating negative ions that attach to airborne particulates, helping to remove odours. Research indicates these devices can improve air quality and may positively impact mental well-being (Mason et al., 2019). However, like ionizers, some models can produce ozone, necessitating careful selection.
