What do you mostly cut?

Estimates based on public OEM list prices (July 2026) and a ~150 cutting-hour cartridge life at mixed workload. Actual filter life varies with material and machine. PURE-AIR figure reflects typical modular-stage replacement economics (~50% of the lowest OEM path); exact filter pricing available on request.

Why modular beats sealed cartridges

Sealed OEM cartridges bundle pre-filter, HEPA and carbon into one disposable block — when the cheap pre-stage clogs, you throw away the expensive HEPA and carbon with it. PURE-AIR separates the stages: the low-cost F5/F9 pre-filters take the abuse and swap in seconds, while the H14 HEPA and treated-carbon bed keep working for 3-4× as long. Subscribe to filter sets and save another 15%.
