Filter Strength Modulation

Changing and replacing the filter is a user friendly process. We have provided 2 filter types (one low density and one high density) for the user to interchange based on pollution levels in the environment. Each pack contains 50 filters, for long-term use of the product (more filter packs are available for purchase separately).

Filters Tested for Optimal Efficacy

  • Scientifically Tested: Hari Hats has been scientifically tested to confirm its filters’ efficacy on capturing harmful particulate matter (PM) in a harmful geometric range.
  • Filters Small & Large Harmful Particles: PM2.5 represents airborne pollutants with a diameter of 2.5 micrometers (um) or less, such as wildfire smoke, dust mites and pet dander. PM10 represents those with a diameter between 2.5 and 10um, such as vehicle exhaust and pollens. For comparison, a human hair is 50-70um thick.
  • Effective Indoors & Outdoors: In both ambient conditions, Hari Hats’ low and high density filters reduced small and large particles in the air around an individual’s breathing zone by a very significant margin compared to no filter.
