3. About

BuyBySpecs exists to simplify air purifier decisions using measurable performance instead of marketing claims.

Most consumer air purifiers are advertised using maximum coverage numbers that don't reflect real-world use. In practice, effective air cleaning depends on factors like usable airflow, air changes per hour, noise at practical speeds, and long-term filter costs.

This site focuses on those measurable factors.

Recommendations are based on how air purifiers perform in everyday conditions, not on advertised maximums or feature checklists.

BuyBySpecs does not sell products directly. Some links may be affiliate links, which means a commission may be earned at no additional cost to the user. Affiliate relationships do not influence how products are evaluated or recommended.

The goal of this site is simple: to help people choose air purifiers that actually work for their space, without unnecessary complexity.
