Highest PPM of Portable Ozone output available on eBay!
An incredibly high output of 280 PPM!!
In the universe of ozone, all that matters is PPM (parts per million) of ozone for a given air flow rate, not the amount of grams per hour like some units boast. Grams can be greatly exaggerated by lab tests using high unrealistic air flow rates. Most other ozonators are at 100 PPM or below when compared at the same low air flow rate the DEL unit is rated at (scfh= standard cubic foot of air per hour). This stat is the key to understanding and comparing units. If an item does not state the "scfh" used to get the results stated, the grams/hour mentioned (or any other unit of measure) are meaningless and usually misleading. Buyer beware if this stat is omitted, there is usually a reason...
Because of its superior engineering, the DEL is able to deliver this incredibly high concentrated output at a very low air flow rate. Ozonators naturally operate at a very low air flow rate so this is how you want to compare how different units will operate in the real world.
This DEL unit beats them all when you know what to look for!
