"Best Company Ever!"

Dr. Robert Harris DMD Dentist, KY, USA
American College of Integrative Medicine and Dentistry
Vice President

"Longevity Resources is the absolute best company I have ever dealt with , bar none! In 2007 my whole approach changed when we purchased the Longevity Ozone Generator with Foot Pedal and Remote Control Ozone Output port. The Longevity Ozone Generators I have, have never needed to go back for any type of maintenance."


"Impressive Reliability"

Dr. Dennis Harper DC, Idaho USA
President, Gem State Holistic Health

"I've looked at 20 different ozone generators. I've been impressed with Longevity's because of the reliability, and especially from the support of the company itself. It is the only Ozone Generator I would recommend in the USA or North America for professionals to use. I appreciate Longevity very much; they have been a blessing to me. I am happy to recommend that anyone use Longevity's equipment."

Dr. Mark Weiser Ozone Dentist

"Very good customer service; I love them"

Dr. Mark Weiser, DMD, CA USA

"I've been using ozone for over 20 years and started early on with Longevity ozone generators. I love the product, it is very low maintenance. I don't call the office very often because I don't have any maintenance issue. When I do call the Longevity office to order something, they are very responsive, and I get things to my door within a very short period of time. Very good customer service. I love them."

"Phenomenal Reliability and Customer Support"

Dr. Charles Ruefenacht, CA USA
Innovative Dental Solutions

"I've been using ozone for about 18 years. I use it all day long and the Ozone Generator that I use is Longevity's Quantum 3 Ozone Generator which has worked without a flaw for 18 years, day in day out. The customer service is great, there is always a voice that answers and never a canned message, and they are quick to respond. I need ozone; I can't live without it. Ozone is an essential part of my day."

Dr. John Monagle

Longevity = "Gold Standard"

Dr. John Monagle ND, CA USA

"I use Longevity Resources...that is the "Gold Standard" for ozone generators. I've been using the EXT120-T since 2009 and it's been problem free, no issues at all...I originally went with Longevity because their customer support is fantastic, but then the actual equipment...it's "die hard". 


"After 18 years...still works perfectly"

Dr. Michael Nowazek, AB Canada
President, Canadian Naturopathic Association

"I have had my ozone generator since May 2001...used it daily, 5 days per week..I have NEVER had a problem with it. It still works as perfectly as the day I bought it. The concentration is the same, the effects are the same. I never have to worry...I can completely count on my machines from Longevity to work. I think that every company could learn from Longevity's dedication to quality product and customer service."
