Summary
- EPA List H identifies disinfectants proven effective against bacterial spores like Clostridium sporogenes and Bacillus subtilis.
- Spores are highly resistant, making List H products critical for labs, healthcare, and biotech facilities.
- OxiTab qualifies for List H and offers safer, non-hazardous protocols than bleach.
- Short paragraphs make training and adoption easier for frontline teams.
- Credible references include EPA and CDC disinfection resources.
Why Sporicidal Disinfection Matters
Spores can survive for months on surfaces and resist many cleaning methods. They require stronger disinfectants to inactivate.
EPA List H identifies products tested specifically against spore-forming bacteria, ensuring higher-level disinfection.
What EPA List H Means in Plain Language
List H is EPA’s list of sporicidal disinfectants. To qualify, products must kill Clostridium sporogenes and Bacillus subtilis spores on hard, non-porous surfaces.
These organisms serve as indicators for spore efficacy. See the EPA List H page.
The Challenge Of Spores
Bacterial spores resist heat, drying, and many disinfectants. They are tougher than routine pathogens like staph or salmonella.
This makes List H products critical in laboratories, hospitals, and biotech sites where sterility is non-negotiable.
Where OxiTab Fits In
OxiTab qualifies for List H with validated sporicidal claims. It delivers effective results without the hazards of bleach.
One tablet per gallon ensures consistency across shifts. It supports staff training with simple instructions.
- Healthcare: terminal cleaning in rooms and ORs.
- Biotech: labs, research suites, and controlled environments.
- Education: microbiology teaching labs and classrooms.
For spore-specific pathogens like C. diff, review our List K explainer.
Applications By Setting
Healthcare
Use OxiTab for terminal cleaning after spore contamination. Keep surfaces wet for the full label minutes.
Disinfect equipment, rails, and high-touch surfaces in patient care areas.
Research and Biotech
Apply in controlled labs to reduce contamination risk. Train staff on mixing and dwell time.
Use visible timers for compliance and record logs for audits.
Education and Training Labs
Use in microbiology classrooms to maintain safe environments. Focus on benches, sinks, and shared instruments.
Store tablets safely and mix fresh daily for consistency.
Why OxiTab Over Common Alternatives
Bleach kills spores but is corrosive, damaging, and unpleasant to handle. It creates harsh fumes and surface damage.
Quats are not sporicidal and do not qualify for List H. They lack the efficacy needed against spores.
OxiTab balances efficacy with safety. For context, read this HOCl vs bleach primer and this clinical explainer.
Implementation Tips For Reliable Results
- Consistent dilution: One tablet per gallon, mixed fresh daily.
- Wet contact time: Keep surfaces visibly wet for the full label minutes.
- Surface checks: Confirm compatibility with sensitive equipment.
- Logs: Track operator, area, and time for compliance.
Credible Resources For Teams

The Smarter Choice For Sporicidal Disinfection
List H confirms disinfectants tested against tough bacterial spores. OxiTab adds safety, simplicity, and ease of use.
One product helps facilities cover routine pathogens and spores across multiple EPA lists. This saves time and builds consistency.
Frequently Asked Questions
What is EPA List H?
List H is the EPA’s list of sporicidal disinfectants effective against bacterial spores like Clostridium sporogenes and Bacillus subtilis on hard, non-porous surfaces.
Why are spores harder to kill than other pathogens?
Spores have tough protective layers that resist heat, drying, and many disinfectants. Specialized sporicidal products are required for inactivation.
Does OxiTab qualify for List H?
Yes. OxiTab has validated sporicidal claims and is EPA-registered for hard, non-porous surfaces when used as labeled.
Is OxiTab safer than bleach for spore disinfection?
Yes. OxiTab is non-hazardous and easy to mix. Bleach is corrosive, produces harsh fumes, and damages finishes.
Where should List H products be used?
Use in healthcare, biotech, labs, and educational settings where spores may be present. Focus on high-touch surfaces and controlled environments.
