- HEPA Filters: High-Efficiency Particulate Air (HEPA) filters trap 99.97% of particles that are 0.3 microns in size, including dust, pollen, and pet dander. These filters do not release any harmful byproducts into the air, making them one of the safest options for allergy sufferers and those with respiratory issues.
- Activated Carbon Filters: These filters use activated carbon to absorb odors, volatile organic compounds (VOCs), and other harmful chemicals from the air. They are particularly effective in kitchens and areas with strong smells, and since they do not emit any harmful substances, they contribute to a safer indoor environment.
- UV-C Light Purifiers: Ultraviolet light air purifiers use UV-C light to kill bacteria, viruses, and mold spores as they pass through the device. While effective at sanitizing the air, users should ensure the device is designed to prevent UV exposure, as direct exposure can be harmful to skin and eyes.
- Ionic Air Purifiers: Ionic purifiers release negatively charged ions into the air, which attach to positively charged particles like dust and allergens, causing them to settle out of the air. Safety can be a concern with some models that produce ozone as a byproduct, so it’s important to choose models that are certified to emit low or no ozone.
- Photocatalytic Oxidation (PCO) Filters: PCO technology uses a catalyst, usually titanium dioxide, in the presence of UV light to break down pollutants into harmless substances like carbon dioxide and water. This method is considered safe as it does not generate ozone or other harmful byproducts, making it a beneficial option for indoor air purification.
