Seat, lid, and contact surfaces
Wipe after visible soil and at least daily with a pH 6–9 nonabrasive detergent or compatible quaternary-ammonium wipe. Up to 70% isopropyl alcohol is limited to the hard seat, lid, and exterior.
Safety and compliance
Operating boundaries
and safe handling.
Desk Toilet One is an adult personal-use product concept. The current engineering program covers load, closure, battery, cleaning, transport, and data handling. No certification is implied before the final configuration completes the applicable review.
Containment architecture
Mechanical
closure sequence.
The C12 uses one closure inside the unit and a second cap for transport. Both operate mechanically. Its headspace remains connected to a passive filtered pressure path when powered airflow is unavailable.
- 01
Occupied
Low-pressure filtered airflow runs through the isolated cartridge chamber while the mechanical shutter is held in its operating position.
- 02
Closed
Removal of load closes the spring-return shutter and double radial gasket before the post-session filtered purge begins.
- 03
Transport sealed
C12 removal closes a second mechanical cap. The tamper-evident seal and NFC service state are verified before handoff.
Engineering validationExplore AirSeal and C12
The 99.99% containment figure is an internal design objective, not a certified performance claim. Final closure test methods and acceptance criteria remain in validation.
Powered airflow
Air enters around the seat opening, crosses the cartridge headspace, passes through the rear-right AirSeal cassette and downstream fan, then exits through the downward rear outlet.
Passive pressure path
A hydrophobic liquid-blocking path connects the installed C12 to AirSeal. The transport cap has a passive filtered pressure-equalization membrane. Sealed does not mean hermetically gas-tight.
Approved use
Material accepted by
the C12.
The proposed pilot permits ordinary urine, feces, and standard dry toilet paper. Liquid and solid material remain together in one rigid sump. The cartridge contains no customer liner, additive, absorbent charge, or treatment medium.
Permitted
- Ordinary urine and feces during personal use
- Up to 15 g of standard dry toilet paper per session
- Ordinary use by a person taking medicine as directed
Prohibited
- Wipes of any kind, menstrual products, diapers, or cleaning wipes
- Food, oils, wash water, intentionally poured liquid, cleaners, or additives
- Loose medication, chemicals, sharps, batteries, clinical material, or known infectious waste
After accidental prohibited input, stop use, leave the C12 installed, report Inspection required, and identify the material to service. Do not remove, open, empty, mail, recycle, or place the cartridge in ordinary trash.
Care and handling
Cleaning and
inspection.
Clean only the user-accessible surfaces named in the maintenance card. The cartridge shutter, air path, and material below the radial gasket are not customer-cleanable.
Panels, enclosure, and floor
Wipe and dry the removable panels and receiver ring, then reseat them fully. Wipe the enclosure and clean the hard floor beneath the secured unit. Apply cleaner to a cloth, never directly to the product.
Keep liquid out of the assemblies
Do not use bleach, chlorine, ammonia, mixed chemicals, acids, alkalis, solvents, concentrated peroxide, abrasive tools, steam, immersion, direct spray, or pressure washing.
Replace the AirSeal cassette
With the lid closed and C12 seated, disconnect power, wear gloves, press both rear-right cassette tabs, and pull the closed cassette straight out. Do not open it. Seal it in the supplied sleeve.
Reset and check airflow
Insert the keyed replacement until both tabs click. Restore power, hold the recessed filter control for three seconds or confirm in Cloud, and wait for the airflow baseline. Reseat once on failure, then contact service.
Stop at the cleaning boundary
Visible material in the bay, shutter, air path, or below the gasket is not customer-cleanable. Do not spray, reach inside, or attempt an internal repair. Restrict access and request service.
| Unit state | Permitted action | Required response |
|---|---|---|
| Ready | Normal adult personal use | Confirm a level hard surface, engaged locks, and seated C12 |
| Capacity advisory | Normal use remains available | At 75% of the 9.6 L working volume, confirm exchange inventory and route |
| Collection ready | No new session should begin | At 9.6 L, day 10, or an earlier rule, prepare a sealed exchange |
| Capacity lock | No use; removal only if explicitly cleared | At 10.8 L or day 14, request service if shutter contact is possible |
| Seal check failed | No use or collection handoff | Return the lever and reseat once; restrict access and request service if the second check fails |
| Temperature hold | No use, removal, or transport until cleared | Keep the unit indoors and follow service guidance |
| Damage or leakage | Do not move, clean internally, or attempt repair | Isolate access and contact the service response line |
Household and workplace safety
Installation and
access limits.
DT One is for one adult operator in a visually private indoor workspace. It requires a 30 in wide × 24 in deep unobstructed desk opening, a level approved hard floor, and access to the cartridge and filter service paths.
Limit access
Keep children and pets away during use, cleaning, and any time the cartridge bay is open. Store detached C12 cartridges upright, mechanically capped, and beyond their reach.
Set before occupancy
Use only on a level hard surface. Engage all caster locks, lower stabilization feet, confirm the height index, and keep total static load within the 300 lb engineering target.
Provide visual privacy
A private home office, enclosed single-person office, qualified private coworking office, or approved lockable booth may be eligible. Exposed open-plan desks, cubicles, shared rooms, and freestanding screens are not permitted in the founding pilot.
Mechanical and electrical safeguards
Operation during
power loss.
A loss of power stops air handling, sensing, service indicators, purge, and Cloud synchronization. It does not open the cartridge or defeat the mechanical closure path.
Mechanical safe state
Finish the active session, remove load, and close the lid. The spring-return shutter closes and passive filtered pressure equalization remains. Connect power, then wait for the restart purge and seal check before reuse or exchange.
Lithium iron phosphate
The planned 74 Wh battery uses a monitored charging system and USB-C PD at up to 65 W. Battery transport testing targets UN 38.3 for the final launch configuration.
Regulated and time-limited
Studio seat regulation targets 86–100°F and requires direct power. Heating shuts off automatically after 15 minutes and is disabled during fault, service, and transport states.
Use only the supplied or approved power equipment. Do not operate with a damaged cable, wet connector, submerged housing, or outside the 50–86°F / 10–30°C indoor operating range.
The emergency release is a service-only carriage control. It does not override the transport-cap interlock and is not part of customer cartridge exchange.
Transport and processing
Collection eligibility
and transport.
A removed C12 remains in customer custody until an authorized operator records Accepted into custody. Before that event, keep it upright in its rigid vessel for no more than 72 hours after sealed removal at 50–77°F / 10–25°C.
- 01
Eligibility check
Seal, age, fill, temperature, route, and local processing rules determine whether collection can proceed.
- 02
Contained pickup
An authorized collector scans the C12 and places it inside a reusable rigid transit vessel without opening it.
- 03
Custody record
Pickup, transfer, processing receipt, sanitization, and return-to-pool events are recorded against the cartridge identifier.
- 04
Approved processing
De-identified batches move only to permitted stabilization, digestion, research, wastewater, or thermal-recovery partners.
Collection accepted
- Mechanical transport cap fully closed
- Tamper-evident seal intact
- Age and temperature history inside the local service window
- NFC identifier and service state readable
- Authorized route and processing capacity available
Collection held
- Seal fault, visible damage, leakage, or puncture
- Prohibited material reported or detected
- Temperature or storage interval exceeded
- Custody identifier unavailable
- Local transport or processing eligibility suspended
Store before handoff
- Secure indoor service area; dry and protected from heat, sunlight, impact, food handling, children, and public traffic
- Transport cap uppermost inside the latched rigid vessel
- No ordinary curbside placement; a confirmed Home Scheduled window may allow up to 60 minutes in the approved vessel
If collection does not proceed
- Return the vessel indoors immediately and keep the original storage clock
- Use the printed identifier and 2D code if NFC cannot be read; the collector must record manual verification
- For damage, leakage, or unconfirmed closure, do not move or improvise an overpack; restrict access and request inspection
Do not open, puncture, mail, privately transport, burn, recycle, home-compost, refrigerate with food, or place a C12 in municipal trash. If two cartridges are full or held, stop using the unit and request priority exception service.
Biological processing boundaries
Processing
limitations.
No digestion, composting, power generation, or material treatment occurs at the desk. Compatible de-identified batches may enter controlled stabilization, anaerobic digestion, research, wastewater, or thermal-recovery pathways only where the facility, material, and local rules permit.
Residual material follows the receiving facility’s permitted process. Desk Toilet does not market untreated material for direct use on farms, gardens, or crops, and environmental attributes remain estimated or eligible unless verified under an applicable methodology.
Review BioCycle RecoveryTesting and certification roadmap
Testing and
certification status.
Internal tests guide the engineering program. A regulatory mark will appear only after the final hardware configuration completes the applicable third-party or authority process.
| Program | Target or objective | Current status |
|---|---|---|
| Static load | 300 lb / 136 kg | Engineering target · validation in progress |
| Acoustic profile | ≤38 dBA at 1 m | Controlled prototype target; not a certification |
| Seal integrity | 99.99% containment objective | Internal objective across normal-use and transport-state testing |
| Battery transport | UN 38.3 | Certification target for launch battery configuration |
| Radio authorization | FCC / ISED | Authorization target for Wi-Fi and Bluetooth LE hardware |
| Electrical safety | Applicable launch-market standard | Final configuration and certification body under review |
| Transport vessel | DT-LG internal protocols | Design validation only; not transport, aviation, or regulatory certification |
Concept specifications may change as validation, supplier qualification, certification, and regional compliance work progresses.

- Occupied or unoccupied state; raw pressure discarded
- Fill, seal, temperature, and filter pressure
- VOC proxy for AirSeal service estimation
- Battery, connectivity, and diagnostic state
- Cartridge identity and collection eligibility
The system does not include
- Camera or microphone
- Biometric or body-weight estimation
- Health diagnosis or composition analysis
- Named session history for enterprise administrators
- Exact live occupancy history in DT Fleet
30-day retention target
Optional personal event detail is targeted for 30-day retention. Personal aggregates are targeted for 13 months, with account export and deletion controls subject to legal requirements.
Delayed and anonymized
Organizational analytics require at least 10 participating units and 30 events, with a delay of at least 24 hours. Utilization is separated from assignment and support identity.
Benchmark participation
Personal accounts may decline anonymous benchmarking. The setting is explicit: “Do not include me in team benchmarks.” Core device service remains available.
Frequently asked questions
Product
operating limits.
These answers describe the current product model. Final installation and handling instructions will depend on the validated hardware and the launch region.
Is Desk Toilet One a medical device or accessibility fixture?
No. DT One is an adult personal-use concept and is not a medical device, clinical commode, or substitute for accessible restroom facilities or building sanitation infrastructure.
What happens if power or connectivity is lost?
At zero battery, the fan, sensors, indicators, purge, and Cloud sync stop. The primary shutter closes mechanically when load is removed, and passive filtered pressure equalization remains. Close the lid, connect power, and wait for the restart purge and seal check before reuse or exchange. An internet connection is not required for closure.
Can I empty or clean a collected C12 cartridge myself?
No. Customers never open, empty, puncture, pressure-wash, mail, recycle, burn, or home-compost a collected cartridge. Authorized service partners exchange, process, sanitize, inspect, and return C12 units through the service pool.
What material is not permitted?
Wipes, menstrual products, diapers, food, wash water, loose medication, chemicals, sharps, batteries, clinical material, and known infectious waste are not permitted. Standard dry toilet paper is permitted up to the proposed 15-gram per-session limit.
Can the unit be used around children or pets?
The product is intended for adult personal use. Keep children and pets away from the unit during use, cleaning, and any time the cartridge bay is open. Store detached cartridges upright, capped, and inaccessible.
Does AirSeal disinfect the room?
No. AirSeal uses activated carbon and zeolite to contain and filter chamber air. It is not a room air purifier, pathogen-control device, sterilization system, or diagnostic instrument.
Where does collected material go?
Where approved infrastructure exists, sealed and eligible material may enter controlled stabilization, anaerobic digestion, research, wastewater, or thermal-recovery pathways. No processing occurs at the desk, and untreated material is not marketed for farms, gardens, or crops.
What can an employer see?
DT Fleet administrators can see device health, inventory, service state, fleet availability, delayed anonymized patterns, and modeled planning estimates. They do not receive named session histories, body metrics, personal resource credits, or exact live occupancy history.
