The short versionThe patient's medical team can prescribe the chemotherapy, perform the transplant, or manage the immunosuppression. They cannot make the home safe — that is a separate problem with a separate set of tools. We deliver hospital-grade hydrogen peroxide disinfection to the patient's residence, calibrated to the immunological status, coordinated where appropriate with the physician of record, ATP-verified, and documented to chart-grade standard. We arrive in unmarked vehicles and sign a mutual NDA. The protocol is what the family would build for themselves if they had a hospital infection-prevention team on retainer.
The gap between hospital and home
A solid-organ transplant recipient is discharged from Jackson Memorial, Cleveland Clinic Florida or the University of Miami transplant program on an immunosuppression cocktail — tacrolimus, mycophenolate, prednisone, sometimes induction antibodies. For the first 6-12 months, the patient is functionally immunocompromised by design: the same regimen that prevents organ rejection also disables the immune defenses against opportunistic infection. CMV, BK virus, EBV, Pneumocystis, Aspergillus, common gram-negatives — all become elevated risks. The transplant team manages this with prophylactic antimicrobials, surveillance labs, and patient education. What they cannot manage is the patient's environment.
The same gap exists for the chemotherapy patient discharged from the infusion center with an ANC below 500. For the lupus patient on cyclophosphamide plus rituximab. For the child with severe combined immunodeficiency. For the elderly grandparent on chronic prednisone for autoimmune disease. The hospital's infection-prevention team does extraordinary work inside the four walls of the unit; once the patient goes home, the gap opens.
Blanc Estates closes that gap — not as a substitute for the medical team, but as the environmental infection-prevention layer the medical team often recommends and rarely has a provider for.
What our sensitive household protocol includes
Confidential Walk-Through
Visit by Operations Director Julio García, on a date the family chooses, in unmarked vehicle, with mutual NDA signed in advance. We tour the home, identify high-risk zones (bedroom, ensuite, kitchen, the patient's primary living areas, HVAC layout), review household composition, pets, visitor flow, current cleaning service, and discuss the patient's medical situation in whatever detail the family chooses to share.
Physician Coordination (if requested)
When the family asks, we provide a protocol summary to the patient's oncologist, transplant coordinator or immunologist for review. Several Miami transplant and oncology programs have endorsed the approach as appropriate complementary infection-prevention. The post-cycle ATP report can be added to the patient's chart.
Cycle Calibrated to Immune Status
Weekly during peak neutropenia (ANC < 500). Bi-weekly during active chemotherapy or first 90 days post-transplant. Monthly during longer-term immunosuppression maintenance. On-demand response within 24 hours after exposure events: a visitor arriving with illness, post-renovation dust, pet illness, suspected mold, hurricane recovery.
Hydrogen Peroxide Micro-Nebulization
The Medibios system disperses a calibrated mist of CE Class IIa · FDA-listed Evolyse Strong throughout the home. Coverage includes bedrooms, bathrooms, kitchen surfaces, living areas, HVAC registers and high-touch points patients reach for without thinking (light switches, doorknobs, refrigerator handles, faucet handles, remote controls, phone surfaces). No residue, no odor, no surface impact.
Pre and Post-Cycle ATP Verification
Critical surfaces — the bed surround, kitchen prep area, the patient's primary chair or sofa, bathroom fixtures — are swabbed before and after the cycle with a 3M Clean-Trace luminometer. Target: RLU < 10 (clinical threshold). Any surface that fails verification is re-treated and re-tested before we clear the space.
Chart-Grade Documentation
You receive a one-page summary suitable for the patient's medical file plus the underlying dossier: cycle parameters, product lot, FDA registration, ATP readings before/after with photo of swab sites, operator (Julio) signature, date and time. Subscription clients receive a quarterly consolidated report.
Why dry H₂O₂ micro-nebulization and not everything else
The honest answer is that most options sound impressive in marketing and do not perform in validated testing. UV light requires line of sight; it does not reach the spaces an immunocompromised patient actually inhabits. Ozone degrades plastics and electronics and creates secondary toxicity. Quaternary ammoniums and chlorine leave residue, can stain finishes, and are not appropriate for daily contact in a household with a vulnerable family member. Conventional fogging with 10–50 µm droplets misses the spaces aerosols and pathogens actually reach. The Medibios system is different: a patented calibrated turbine (US Patent 9,662,671 B2) releases hydrogen peroxide particles between <1 and 5 micrometers — fine enough to behave like a gas, reach every surface, then break down into water and oxygen. Independent validation studies document 100% kill rate on biological indicators (Mario Negri Institute) and 91.6% bacteria reduction in operating rooms (Jackson Memorial Hospital). That is the technology we use.
The device (Medibios) is classified as a Class I medical device by the US FDA. The disinfectant (Evolyse Strong) carries CE Class IIa classification (CE 0426) and is Registered and Listed by the FDA as Medical Device Class I. See the technical breakdown.
What discretion looks like in practice
For our luxury residential clients — Bal Harbour, Indian Creek, Star Island, Fisher Island, the upper floors of Brickell and Sunny Isles, the older Coral Gables and Pinecrest estates — discretion is non-negotiable. The family does not want the building staff, the neighbors, or their social circle to know that someone in the home is in active medical treatment.
We respect that fully. Unmarked vehicles. Plain clinical attire instead of branded uniforms for residential visits if requested. Mutual NDA signed before any walk-through. No photography of the home or property without explicit written consent. Every client name, every address, every detail of every engagement — confidential. We have served families where this is the operative requirement; the names do not leave our database, and that is the only way the relationship works.
What we are not
We are not a substitute for medical care. We do not diagnose, treat or counsel medical conditions. We do not provide nursing, in-home health aide services, or anything that requires a clinical license. We do not interfere with the patient's medical team, contradict medical advice, or position ourselves between the family and the physician.
We are the environmental infection-prevention layer — the equivalent of a hospital's facility hygiene program, scaled down to a single home, coordinated with the family's medical team, and documented at chart grade. That is the specific role we play, and we stay inside it.

Ing. Julio García Puerto, our Operations Director, brings 35 years of hospital biosafety experience to your home. He is the co-author of 14 official biosafety manuals for medical equipment, an ATP testing specialist with 3M Clean-Trace instrumentation, the former Exclusive Representative of Amil Care Corp, and Technical-Commercial Advisor for the Medisystem H₂O₂ platform. He designed disinfection protocols for ICUs, dialysis units, surgical theaters, ambulances, and enteral and parenteral nutrition compounding centers across the Dominican Republic.
If your oncologist or transplant coordinator asks for the credentials of the team treating the home, this is what we send them. Read the full bio.
The Amil Care framework — why the FDA matters
The Medibios device and Evolyse Strong disinfectant are FDA Class I medical devices. Blanc Estates operates under the federal authorization of Amil Care Corp USA, the manufacturer, headquartered in Hialeah, Florida. This is the same regulatory framework that allows our team to operate inside hospitals and dialysis centers. When applied to a private home, it means the protocol carries the same compliance backbone, the same product chain-of-custody, and the same documentation discipline as the hospital where the patient was treated. See the partnership framework.
A typical sensitive household cycle for a 4,000-8,000 sq ft Miami home falls in the $1,200-2,400 range depending on coverage, frequency and documentation level. Subscription packages for households in active treatment phases bundle weekly or bi-weekly cycles, 24-hour on-demand response, physician-coordinated documentation, and quarterly reports at a monthly rate typically 25-40% below the equivalent on-demand cost. Written, confidential quote within 48 hours of the walk-through.
