Deodorizing mechanisms and the odors they target vary by product. Several products use silver (Ag), so check the packaging and manufacturer’s description when buying.

Disposal methods to reduce odors from used diapers

Odors from used diapers tend to become more noticeable over time. After changing, dispose of them as soon as possible using the following methods.

Flush stool down the toilet

Remove as much stool as practical from the diaper and flush it down the toilet before disposal. Also check your municipality’s waste-sorting rules.

This extra step can considerably reduce odors.

BOS Odor-Proof Bags

Putting a used diaper in an odor-proof bag and sealing it securely helps control odor during storage. Choose a bag that fits the diaper’s size.

Diaper pails (diaper disposal bins)

Some lidded diaper bins are large enough for adult diapers. Options include deodorizer-equipped bins and dedicated cartridge systems. Choose according to the available space and the amount to be disposed of.

Wrap in newspaper

Wrapping a used diaper in newspaper, then placing it in a bag and sealing the opening, helps contain odors.

Places where odors linger besides diapers

Odors in clothing and bedding

Urine that leaks onto trousers and dries may be hard to notice visually. Check clothing, bedding, and wheelchair cushions for lingering odors. A detergent designed for urine odors is another option for laundry.

Urine left on floors or walls can cause room odors. Wipe away the soiling, ventilate, and use products designed for urine odors as needed.
