Trends and Insights
Health shocks, pollution and wildfire events are redefining baseline demand for air purifiers
- Over the current period, COVID-19, rising respiratory illnesses and repeated wildfire smoke events have moved air purifiers from nice to have to must-have products in many US homes, schools, and offices. The diverse range of air quality issues has attracted support from health awareness and concerns about indoor air quality, even after the initial pandemic spike. This shift has strengthened recurring replacement sales and smoothed demand volatility relative to pre-2020 patterns.

Trends and Insights
Tightening indoor air quality codes will elevate specification standards
- State and federal agencies, as well as standards bodies, are expected to tighten indoor air quality requirements for schools, healthcare facilities and high-density workplaces, often by codifying minimum filtration efficiencies and ventilation rates. This will likely push building owners toward higher-spec HEPA and ULPA-grade systems, which will favor manufacturers able to certify performance against ASHRAE, EPA, and OSHA guidelines.
