Mild hyperbaric oxygen therapy (mHBOT) is a booming cash-pay wellness category. Soft-shell chambers run at 1.3 to 1.5 atmospheres. That sits below the 1.5 ATA threshold the UHMS uses to flag unproven therapy (UHMS Position Statement, 2024).
The FDA only clears these low-pressure chambers for acute mountain sickness (FDA Consumer Update, 2024). Every other use is off-label. That includes autism, long COVID, anti-aging, and brain fog. Operators can legally sell sessions. They cannot legally market unapproved claims.
This guide ranks ten US clinic chains offering mHBOT. Pricing reflects verified 2026 rates where posted (BaricBoost market data, 2026).
At a Glance: 10 mHBOT Clinic Chains Compared

1. Restore Hyper Wellness — Largest National Footprint (Verdict: Best national mHBOT access)
Restore Hyper Wellness runs 200+ studios in 40 states (Restore corporate site, 2026). That makes it the largest mHBOT chain in the country. Studios use soft chambers at 1.3 ATA for 60-minute sessions.
Pricing varies by market. Restore lists first-time sessions at $75 in many markets (Restore promo page, 2026). Regular member pricing runs around $99 to $120. Most studios bundle mHBOT with cryotherapy, IV drips, and red light therapy.
Staffing is wellness-tech focused, not clinical. Restore keeps marketing language to recovery and performance (Restore services page, 2026). The company avoids disease claims.
The chain targets athletes and biohackers. No physician oversight on-site at most studios. The UHMS notes mask leaks reduce delivered O2 well below 95% (UHMS, 2023).
2. OxyHealth Partner Network — Largest Soft-Chamber Footprint (Verdict: Largest soft-chamber footprint)
OxyHealth has distributed 18,000+ chambers globally (company about page, 2024). Its chambers appear in over 3,000 US physician offices, chiropractic clinics, and wellness centers.
The manufacturer does not operate clinics directly. Instead, partner sites buy Vitaeris 320, Solace 210, or Respiro 270 units. Typical sessions at partner clinics run $60 to $150. Pricing depends on location and pressure rating.
Chambers operate at 1.3 to 1.5 ATA. The Vitaeris 320 dominates chiropractic offices. It seats one adult plus a child or pet.
Over 500 pro athletes use these chambers per company marketing. Clinical oversight varies wildly by partner site. Some are physician-supervised, others are unstaffed self-service rooms.
3. Hyperbaric Centers of Texas — Largest TX Wellness-Adjacent Network (Verdict: Best Texas multi-modality option)
Hyperbaric Centers of Texas runs out of Richardson (clinic site, 2026) as part of Johnson Medical Associates. The clinic offers hard chambers at 1.5 to 2.4 ATA and soft mHBOT options.
Pricing is not posted publicly. Industry benchmarks suggest hard-shell sessions run $200 to $400 in Texas (BaricBoost San Antonio guide, 2026). Mild options price 30 to 50 percent lower.
Hours run Monday through Saturday, 7am to 4pm. The medical-practice tie gives more clinical credibility than retail wellness chains.
The center treats FDA-approved indications like wound care alongside off-label uses. Concussion recovery, Lyme, and long COVID are common targets. This dual-track model is typical at physician-owned Texas centers.
4. Aviv Clinics — Most Researched Protocol (Verdict: Best research-backed protocol)
Aviv Clinics in Dallas (Aviv corporate site, 2026) runs the most rigorously studied wellness HBOT protocol in the world. The Hyperoxic-Hypoxic Paradox protocol was developed by Dr. Shai Efrati at Tel Aviv University.
Aviv is technically not mild HBOT. Sessions run at 2.0 ATA in hard chambers. But the company markets to the same wellness-seeking clientele as soft-chamber chains.
The catch is cost. Aviv's 12-week program runs $51,500 individual or $90,000 per couple (Impact Wealth review, 2023). The priciest HBOT program in the US. The protocol includes 60 sessions plus cognitive, physical, and nutritional coaching.
Aviv has published peer-reviewed studies on aging, PTSD, and long COVID. A 2024 PTSD case study showed improvement in elderly veterans (Yahoo Finance, 2024). The company still avoids disease-treatment claims in marketing.
5. iCRYO — Best Cryo + mHBOT Bundle (Verdict: Best mHBOT + cryo bundle)
iCRYO runs 90+ franchised locations across the US (iCRYO HBOT page, 2026). The chain bundles mHBOT with cryotherapy, infrared sauna, and IV drips. Not every location offers HBOT.
Sessions run up to 90 minutes in soft chambers at 1.3 ATA. Pricing at iCRYO runs $50 to $100 per session. Memberships around $200 to $300 monthly bundle multiple modalities.
The chain markets to athletes and recovery clients. Like Restore, iCRYO uses wellness-coded language. "Recovery," "performance," and "feel your best" avoid FDA enforcement on disease claims.
iCRYO's Port St. Lucie franchise (iCRYO PSL site, 2026) actively promotes HBOT. Many franchises offer only cryo and red light. Staffing is wellness-tech focused without physician oversight.
6. Holistic Hyperbarics — Best Northern California Access (Verdict: Best Northern California access)
Holistic Hyperbarics serves the San Francisco Bay Area (Holistic site, 2026) with mild and clinical options. The clinic markets to both wellness clients and physician-referred patients.
Pricing typically runs $100 to $200 per session for mild therapy. Package discounts hit 10 to 20 percent. The clinic offers physician consultation. That sets it apart from retail studios.
The Bay Area has fewer options than SoCal. SoCal Hyperbarics in Encino (SoCal HBOT site, 2026) serves the southern half. Holistic fills the northern gap with chiropractic and naturopathic partnerships.
Conditions targeted include concussion recovery, Lyme, and athletic performance. Autism comes up too, though that use is off-label and controversial. The clinic carefully cites studies rather than promising outcomes.
7. Reviv — Best Vegas + Global Concierge (Verdict: Best Vegas concierge option)
Reviv operates IV and wellness clinics in Las Vegas (Frost Fit HBOT page, 2026). Mild HBOT is available at select locations. Vegas pricing benchmarks suggest HBOT runs $60 to $450 city-wide (Project Wellbeing pricing guide, 2026).
Reviv's model is concierge. Clients pay $125 to $200 per session in a hotel-spa setting. The chain bundles HBOT with IV therapy, NAD+ infusions, and recovery protocols.
The Vegas market is unique. Frost Fit, Revolution Wellness, and Renaissance Health all compete for biohacker tourism dollars. Reviv leans into the lifestyle-medicine angle hardest.
Clinical oversight varies. Reviv employs medical directors at most locations. The protocols stay in wellness territory. No disease treatment claims.
8. MVS Wound Care — Insurance-Eligible Maryland (Verdict: Best Maryland clinical-adjacent)
MVS Wound Care operates in Baltimore (MVS site, 2026). The clinic focuses on FDA-approved indications first. It offers mild HBOT for off-label uses too. Notably, MVS does not charge facility fees and accepts most major insurance (MVS HBOT page, 2026) for covered conditions.
For mild HBOT specifically, sessions are cash-pay. Insurance only covers UHMS-approved indications. Cash pricing runs roughly $150 to $300 per session at higher pressures.
Maryland's HBOT landscape includes GBMC HealthCare (GBMC hyperbarics, 2026) and BluZone MD in Annapolis (BluZone site, 2026) for hospital-grade options. MVS sits in the middle. Clinical credibility with cash-pay wellness options.
This dual model gives clients physician oversight without hospital pricing. UMMC and Hopkins charge far more for the same protocol.
9. Hyperbaric Centers of Florida — Best 7-Day Florida Access (Verdict: Best Florida 7-day access)
Hyperbaric Centers of Florida in Tampa Bay (clinic site, 2026) provides outpatient HBOT seven days per week. That's unusual for the category. The clinic offers hard and soft chamber options.
Pricing for mild therapy typically runs $150 to $300 per session. Package pricing brings per-session costs down 15 to 25 percent.
Florida's wellness market is dense. Genesis Brain Institute in Tampa (Genesis HBOT page, 2026) and National Hyperbaric (National HBOT site, 2026) compete for the same clientele. The 7-day access differentiates Hyperbaric Centers of Florida for recovering patients needing daily sessions.
Conditions targeted include post-stroke recovery, traumatic brain injury, and Lyme disease. All off-label uses where evidence remains preliminary. See the stroke recovery evidence atlas for the full investigational evidence breakdown.
10. Pacific Hyperbarics — Best San Diego Physician-Led (Verdict: Best San Diego physician-led)
Pacific Hyperbarics in Chula Vista (clinic site, 2026) operates under Dr. David Greene. He brings over 12 years of HBOT clinical experience (Cypress Coast site, 2026). The clinic offers mild and higher-pressure options.
Founded in 2015 by retired Navy diver Carlos Dhayer, Pacific sits between wellness chains and hospital settings. Pricing typically runs $125 to $225 per session for mild therapy.
The clinic targets stroke recovery, traumatic brain injury, cerebral palsy, and MS. All off-label uses. The UHMS position paper on autism rejects HBOT as effective treatment (UHMS Autism Position, 2009). Physician oversight gives Pacific more clinical credibility than retail studios. See the cerebral palsy evidence atlas for the full investigational evidence breakdown.
Dr. Greene also leads Cypress Coast Hyperbarics in Salinas. California clients have two physician-led options.
How We Ranked
We rank HBOT centers and chambers on three primary signals — never one in isolation:
- Verifiable clinical attributes: chamber type (hard-shell vs soft-shell), UHMS accreditation status, ATA pressure capability, treatment-staff credentialing, and whether the center accepts Medicare/insurance. Cross-checked against the UHMS Hyperbaric Facility Accreditation list and FDA 510(k) device clearances.
- Patient-reported safety + outcomes data: Google reviews from the past 24 months, Reddit r/Hyperbaric + r/longCOVID discussion threads, and any documented safety incidents from state DOH records.
- Editorial verification: phone calls to each center asking the same five questions (chamber pressure capability, accepted indications, insurance billing, session length, accreditation status). We log responses, including non-responsive practices.
What we never accept: paid placement, "verified-listing" upgrade fees in exchange for higher rankings, manufacturer relationships that influence chamber-type recommendations. Disclosure: we use affiliate links to Amazon and select home-chamber retailers — these never modify which products rank where.
Update cadence: monthly review for chambers, quarterly for clinics. Last-updated date at the top of every article. Report inaccuracies to research@hyperbaricfinder.com — corrections shipped within 72 hours.
Frequently Asked Questions
What is the difference between mild HBOT and clinical HBOT? Mild HBOT operates at 1.3 to 1.5 atmospheres in soft fabric chambers. Clinical HBOT runs at 2.0 to 3.0 ATA in rigid steel chambers. The UHMS defines anything below 1.5 ATA as unproven (UHMS Position Statement, 2024). The FDA only clears soft chambers for altitude sickness.
Does insurance cover mild HBOT? No. Medicare and private insurers only cover the 13 UHMS-recognized indications under NCD 20.29 (CMS, current 2026). All of those require hospital-grade HBOT at 2.0+ ATA. Wellness mild HBOT is always cash-pay.
Is there real evidence for mild HBOT in long COVID or autism? Evidence is preliminary at best. The UHMS position paper on autism rejects HBOT as an effective treatment (UHMS, 2009). Small studies suggest benefit for long COVID. No large RCTs support routine use.
Is mild HBOT safe? Generally yes, but not risk-free. The FDA issued a 2025 safety letter on chamber fires (FDA Letter to Providers, 2025) after serious injuries and deaths. Risks include barotrauma, ear pain, and fire hazard from any 100% oxygen environment.
What is the optimal mild HBOT protocol if I want to try it? There is no validated optimal protocol. The therapy itself is not validated for most marketed uses. Most wellness clinics suggest 10 to 40 sessions of 60 to 90 minutes each. Talk to a physician before starting. Especially if you have lung disease, ear problems, or recent surgery.
