aer1 replacement filter

Listings state HEPA-level capture down to 0.3 microns with reported removal efficiencies up to 99.97% for those particles.

Replacement guidance across listings varies by product: most recommend replacing filters every 6 to 12 months, depending on the specific option.

Listings offer pack counts from 2 up to 12. Some bundles include extra charcoal prefilters bundled alongside the HEPA replacement filters.

Listings cite materials such as polypropylene, activated carbon, plastic components, and cotton for various filter layers and prefilters.

Listings consistently describe installation as simple — remove the old filter and insert the new one — and typically provide a list of compatible models to confirm fit.
