A:
This is a different product from the Oxygenics. The Oxgenics does not include a shower filter to remove chlorine, while the Oxynator does. If chlorine is not an issue for you, the Oxygenics will provide the best pressure. If you'd also like to remove chlorine from your shower water, the Oxnator will give you the highest pressure WITH filtration (the filtration media will always cause a bit of flow restriction). Both are classified as "low flow" in order to reduce overall water usage.
