Side by side
Every brand wins its own comparison chart, so this one says who should skip each device, including the cheapest one, and when the right answer is nothing yet.

A note on the two prices
The store lists a regular price and a current price for each device, so this site shows both. There's no timer and no code, and if the price changes, it changes here.
A note on returns
The bottle is returnable for 90 days because it's the test. The inhalation machines aren't returnable once they ship, for hygiene and regulatory reasons, which is why we ask you to talk to us first. Defective units are replaced, free, within 7 days of delivery, and the bottle carries a 13-month warranty while the inhalation machines carry 2 years. The full policy.
Accessories
The VH600's generator takes a filter that should be replaced every six months. Two come in the pack, so one order covers a year. Shipping is included in the price.
A cap and cannula kit that lets the HydroSpark's hydrogen be breathed instead of drunk. A small taste of inhalation before you decide whether a machine is worth it. It is not a substitute for one.
Paying
One-time prices. No subscriptions, no auto-ship. Klarna and Affirm payment plans are offered at checkout if you'd rather spread it out.
Shipping
Shipping is free within the U.S.; outside it, the rate appears at checkout. We ship the bottle ourselves, usually in one to two business days. The Pulse ships directly from the manufacturer, and the VH600 after the consultation, once we both know it's the right machine for you.
Not sure
Book a free call and ask the people who use these every day. It isn't a sales call; if the right answer is “don't buy anything yet,” that's what you'll hear. Pick a time →
