QAI Approved Products ~ Quality Proven & Guaranteed

All companies will tell you that their products are high quality...even if they are not.

Wouldn't it be great if you had a "fool proof" way to find out if a company is actually telling you the truth? Well...you do! Just make sure that the products the company makes have a Quality and Safety Approval like QAI, CSA, UL, or ETL.

We Can Prove Longevity Products are High Quality

How? All of Longevity’s ozone generators have a QAI Approval from Quality Auditing Institute. This is proof from an independent laboratory, that Longevity's ozone generators have been fully tested, passed all tests, and are proven to be high quality products.


QAI is an independent technical laboratory that takes the ozone generator and runs it through a rigorous series of laboratory tests designed to stress the ozone generator to the maximum, to try to get it to heat up, burn out, catch fire, etc.

They also perform a detail inspection of all of the components to make sure that all of the components are CSA and/or UL Approved components (CSA = Canadian Standards Association; UL = Underwriters Laboratories USA). If the components themselves are not approved they either can’t be used, or they too would have to be rigorously tested to ensure that they abide by the current electrical standards.

QAI  also performs sensitive electrical tests on all of the components to make sure that none of them are being used beyond their electrical ratings. If the product and components pass these rigorous inspections, QAI then inspects the factory to ascertain if Quality Control measures are in place that would ensure that every single ozone generator produced will be as high quality as the one that was tested in the laboratory. If the product and the factory pass all of these inspections, the product is granted QAI Approval. If the product fails, then no QAI Approval.

The 'take home' message here is that QAI, CSA, and UL Approvals are easy to obtain if the product it high quality, and impossible to obtain if the product is not high quality.

The final message is that if an ozone generator does not have a Quality and Safety Approval, it likely is not high enough quality to pass the rigorous tests. Therefore, you should consider buying only an ozone generator that has a Quality and Safety Approval, like Longevity's, because that is your proof of quality.

What do the Buyer's Guides say?:

There are not many 'Buyer's Guides' on the market written by people who have no commercial interest in what you buy. That is, almost all buyer's guides are written by the people trying to get you to buy their product.

However, one Buyer's Guide you might want to consider reading is written by a panel of ozone experts from around the world, and they have nothing to sell. The organization is called the ISCO3.org, a small group of 21 of the world experts on ozone.

The ISCO3.org wrote an ozone generator buyer’s guide called “Guidelines and Recommendations for Medical Professionals Planning to Acquire a Medical Ozone Generator”.  On page 7 they say, “In the United States quality and safety of the product can only be confirmed if the product carries a local Quality and Safety Approval, such as ETL, CSA, UL, or QAI Approval. Products lacking a Quality and Safety Approval should be avoided”. You can review this guidebook here: http://isco3.org/wp-content/uploads/2015/09/ISCO3-DEV-00-01.pdf.
