Why it matters
The LifeSupplyUSA Replacement Filter for Rabbit Air BioGS SPA-421A is a replacement filter.
Made for LifeSupplyUSA's Rabbit Air BioGS SPA-421A purifiers. The model label is usually on the back or under the filter door; match it before ordering.
Construction: HEPA.
Most purifier HEPA filters last six to twelve months in normal use; follow the unit's filter indicator and replace sooner in smoky or pet-heavy homes.
This is the particle stage: the pleated HEPA or HEPA-type media catches dust, pollen, dander and smoke particles, and it gets better at catching them as it loads, until the airflow drops. When the intake side turns gray or the fan sounds strained on its usual setting, it's due.
Use the filter made for your exact unit: purifier filters seal against their own housing, and a close-but-different filter lets air bypass the media.
