Air Purifiers

How we chose best air purifier:

  • Air filtration efficiency: We test air purifiers for their actual ability to remove pollutants from the air.

  • Filtration level: We test air purifiers at different filtration levels to determine which ones are most effective at removing specific pollutants.

  • Efficiency: We test air purifiers to determine how effectively they remove specific pollutants and at what cost.

  • Cost: We test air purifiers to determine their relative cost based on filtration levels and effectiveness.

  • Noise level: We test air purifiers to determine the noise level they emit.

Things to consider:

  • Type: HEPA and activated carbon filters are the gold standard for allergen removal. Some models also feature UV filters to kill germs.

  • Size: Small air purifiers are best for bedrooms. For larger rooms, opt for machines rated for 500 square feet or more.

  • Noise levels: Look for ones with quieter fans, or consider upgrading to a model with a built-in fan.

  • Smart features: Some models can be switched to a sleep mode that gradually lowers the fan speed throughout the night.

  • Easy maintenance: Models with washable filters require less maintenance than ones that only need to be vacuumed.
