The patented seal is a precision-engineered silicone gasket that engages mechanically every time the lid closes. Unlike other pails that rely on the bag itself to contain odor, PurVault's seal closes the chamber — so no odor can escape regardless of how full the bag is.

No. PurVault works with standard 13-gallon kitchen bags — the ones you already buy. We deliberately engineered around bag lock-in because proprietary refill systems are a cost trap. Any major brand works perfectly.

Chamber One receives each diaper when you deposit it. As the lid closes, the mechanism wraps and drops the diaper into Chamber Two, which is the sealed storage area. This means the opening is never directly connected to the stored waste — odor containment is structural, not chemical.

Every 3–4 months under normal use (approximately one newborn's diaper output). We offer a filter subscription at $15 per 3-pack — about $5/month — so you never run out. Replacement takes 10 seconds.

Yes. All materials are BPA-free, phthalate-free, and formaldehyde-free. We are pursuing GREENGUARD Gold certification — one of the most rigorous indoor air quality standards in the world. The silicone gasket uses medical-grade material with no off-gassing.
