Professional-Grade Recovery
Recover at the level your body actually heals at.
Most recovery tools work on the surface — heat, pressure, cold. AEIR works at the cell. CO2 therapy triggers the Bohr Effect, telling your hemoglobin to release the oxygen it's already carrying directly into the tissue that needs it. This is what professional recovery looks like when it stops being about symptoms.

Who it's for
Built for bodies that ask more of themselves.
The competitive athlete
Training volume is the ceiling. Recovery is the floor. If your floor rises, your ceiling rises with it. AEIR compresses the window between hard sessions by delivering oxygen where your tissue actually uses it.

The weekend warrior
You don't get paid to recover — which is exactly why it has to be efficient. Thirty minutes in the suit or twenty with the paste fits between work, family, and the next ride. Less soreness on Monday. More capacity on Saturday.

Post-surgery or post-injury
Tissue doesn't repair without oxygen delivery. Immobilized joints and healing fascia especially. The paste goes exactly where the soreness lives; the suit works systemically while you rest. Both were designed in-clinic, around real patients.
See the science →Two ways to bring AEIR into your recovery.
Both work through the same mechanism. Start with whichever fits your week.

How CO2 therapy actually works
Your blood is already full of oxygen. CO2 is what delivers it.
The Bohr Effect is not exotic physiology — it's the mechanism your body uses every second to send oxygen to working muscle. CO2 produced by metabolism shifts hemoglobin's hold on oxygen and releases it at the tissue.
AEIR's transdermal CO2 raises local tissue CO2 on purpose. Hemoglobin lets go of oxygen exactly where your cells need it — muscle, joint, fascia, skin. Vasodilation opens the vessels. Circulation increases. The tissue oxygenates. Repair starts.
Thirty minutes with the suit. Twenty minutes with the paste. No pain, no downtime, and no crash afterward.

Hot calf after a long run, knee flare-up after a ride, shoulder after a heavy press day. Apply a thin layer, leave it 20 minutes, move on.
Shop Paste →Travel
The 5-pack goes in a Dopp kit. No hydrogel required, no hardware. Race weekend, business trip, training camp.
First-time trial
Cheapest entry into the AEIR mechanism. $99. If it works, the suit is the next step. If it doesn't, you spent $99.
Systemic recovery
One 30-minute session oxygenates full-body. Use it after training, before bed, or as a standing daily ritual.
Training blocks
The suit is built for volume. Daily or every-other-day, the soreness floor stays low. Athletes report compounding benefits over weeks.
At-home clinic quality
The same system used in partner clinics. Set-and-forget recovery — no appointments, no driving, no electricity. A CO2 tank (sourced locally) lasts months.

Clinic-guided
If you'd rather start at a clinic, our partners in Minnetonka and San Diego integrate AEIR into recovery protocols.
In more locker rooms every season.
AEIR CO2 therapy is in use across the NHL — including the Winnipeg Jets, Colorado Avalanche, Detroit Red Wings, and Anaheim Ducks. It's being trialed at top NCAA football programs. It's the recovery modality Barwis Methods integrates into elite performance training. It's cited by Precision Hydration, Red Bull performance, and a growing list of agency partners. All without a single branded logo — just the mechanism, and what it does to tissue.

How to integrate AEIR into your week.
3–5 sessions per week
Most users do best at 3–5 sessions per week with the suit — consistent, habitual, similar to how you'd use any other recovery practice. The paste can be daily and spot-targeted without fatiguing the system.
20–30 minutes
Suit sessions run 20–30 minutes. Paste applications activate on contact and work for ~20 minutes. Longer is not better — the mechanism is calibrated, not arbitrary.
Post-training or pre-sleep
AEIR pushes the body toward homeostasis — the opposite of a stress response. Most people slot it after training or in the evening to roll into sleep. Morning works too; no crash, no stimulant effect.
Stacks cleanly with other modalities
CO2 therapy is additive. Red light, compression, sauna — use them together without conflict. The mechanism is different enough that AEIR tends to multiply the rest of your stack instead of duplicating it.
