Better Air BioLogic Mini — Portable Probiotic Air & Surface Purifier (formerly Better Air)

The BioLogic Mini by EnviroBiotics® (formerly Better Air) is a compact, battery-operated probiotic air and surface purifier for personal spaces up to 300 sq ft. Instead of trapping particles in a filter, it continuously releases EnviroBiotics®—a patented blend of beneficial environmental probiotics—into the room, where they settle onto surfaces and objects and keep working around the clock. It’s chemical-free, virtually silent, and small enough for a car, desk, nightstand, or hotel room.

How a probiotic purifier works

Traditional purifiers pull air through a filter to capture whatever happens to float by. The BioLogic Mini takes a different approach: it disperses beneficial probiotics that blanket both the air and the surfaces of a room. These probiotics consume the organic matter that allergens and odors feed on—such as dust-mite waste, pollen fragments, mold spores, and pet dander—helping reduce the inanimate allergen load on the surfaces you actually touch, not just the air passing through a machine.

Frequently asked questions

Is this the same as the Better Air BioLogic Mini?
Yes. EnviroBiotics® is the current name for the brand formerly known as Better Air (BetterAir). It’s the same probiotic technology and the same BioLogic Mini device.

Is it safe around children and pets?
Yes. EnviroBiotics are chemical-free, fragrance-free, and produce no ozone. The Mini is designed for continuous, everyday use in occupied rooms.

How is it different from a HEPA air purifier?
A HEPA purifier filters particles out of the air that passes through it. The BioLogic Mini treats both the air and the surfaces and objects in the room with beneficial probiotics, so it keeps working on the things you touch—not just the air inside the machine.

How large a space does it cover?
Up to about 300 sq ft—ideal for personal spaces like cars, desks, and bedrooms. For rooms up to 800 sq ft, see the EnviroBiotics Biotica 800.

How often do I replace the cartridge?
Each probiotic cartridge lasts up to 90 days. Refills are available, and a refill subscription keeps the Mini working continuously.

Is it noisy?
No—it runs at under 5 dB, virtually silent, so it won’t disturb sleep or work.

Are there filters to buy or clean?
No filters. You simply swap the probiotic cartridge about every 90 days.
