  • Best For: Removing smoke, odors, and harmful gases.

  • Pros: Excellent for odor control.

  • Cons: Ineffective at capturing dust or allergens.

3. UV-C Light Purifiers

  • How It Works: Uses ultraviolet light to kill bacteria, viruses, and mold spores.

  • Best For: Reducing airborne microorganisms.

  • Pros: Targets harmful microorganisms.

  • Cons: Ineffective against allergens or VOCs.

4. Ionizers and Ozone Generators

  • How It Works: Releases ions or ozone to neutralize pollutants.

  • Best For: Neutralizing odors and small particles.

  • Pros: Effective at removing certain particles.

  • Cons: Can produce harmful ozone; not recommended for allergy sufferers.

5. Electrostatic Precipitators

  • How It Works: Uses electrostatic charges to trap particles.

  • Best For: General air cleaning.

  • Pros: Washable filters reduce replacement costs.
