luckily it worked. I have a calm air eagle 500.0 they had a burnt out transformer. since there were no specifications on the website for this transformer, I called them left a message and got no response. Then I emailed them with a message for specifications on this transformer and got no reply. I took a chance and ordered it because it looked quite similar., had the same terminals on both ends, luckily it worked. It seems to put out a little less ozone than the original transformer, but it did renew up the life of my old air cleaner. Thank you.
Seems to work well. My only concern is it was made in China. I had a different brand that also worked well (also made in China) until it died because of a cracked grey pipe which began leaking. Looks like similar construction to O3 Pure. The technology is great, with little to no detergent and fresh smelling clothes. There are no replacement parts that need to be replaced every few months as there were in our old unit that broke.
A corner pipe in my unit burst after leaving the garage open overnight. Glad we were able to repair this ourselves!
Easy enough to change and got my heater running like new again. Better price than anything I could find elsewhere too!
