Common questions

IQAir or Molekule — which premium is better?

For pure filtration depth and long-term economics — IQAir. For PECO VOC destruction + premium smart features — Molekule. Different theses.

Is HyperHEPA H14 really better than True HEPA H13?

On paper yes — H14 captures 99.5% at 0.003 microns vs H13 99.97% at 0.3 microns. For most consumer use cases (PM2.5, allergens) H13 is sufficient; for ultra-fine particles or virus-scale filtration, H14 wins.

Is PECO real or marketing?

PECO is real photocatalytic oxidation technology backed by Molekule patents — but efficacy beyond HEPA claims have been debated in independent reviews, and Molekule reached FTC settlements clarifying the marketing boundaries.

3-year ownership cost?

IQAir: $1,099 + ~$600 filters = ~$1,700. Molekule: $1,199 + ~$700-900 filters = ~$1,900-2,100. IQAir meaningfully cheaper 3-year.
