Review: It Works - I recently replaced my ozone generator in my hottub. I used to be able to detect the ozone odor in the bubble stream but not anymore so I purchased these strips to test for ozone. I received the product tonight and I had read some reviews saying it read the same no matter what so I ran a side by side test. I took two large shot glasses (directions say about 2 oz) and filled one with hottub water and the other with hot tap water and followed the instructions for testing both at the same time. The tap water showed yellow (no ozone) and the hottub dark green (max ozone reading). So the strips work and so does my ozone gererator!
Review: Definitely works, hard to quantify the actual reading. - Definitely works. Purchased to test the output of a 1-year old ozone generator I suspected of not working. Testing confirmed no ozone present. Installed new generator, ozone definitely present (smell....) & strips give a positive test. But I found it hard to match the shade of green. Had best results when I did a "control" strip using tap water. (See attached photo). Left side was plain tap water, the one on right was the hot tub. Appears to be on the lower end of the scale. If you need to know an *exact* number for some reason, these are a challenge to read. If you just need a yes/no answer on ozone, they work well. Price was reasonable & I'll definitely buy again.

## Questions & Answers

**Q: Bought a homedics® ozone clean 3-in-1 multipurpose ozone generator, will these strips tell me if it is actually producing ozone water?**
A: Good Morning,

If the device is producing ozone the ozone strips should react. 
They should also be able to smell ozone in the water.

**Q: O3 in water or air**
A: Good evening.  This test strip performs tests on water samples only.  Detection range: 0, 0.05, 0.1, 0.2, 0.3, 0.4, > 0.5 ppm (mg/L)

**Q: So what's with the polarized ("hot or cold") reviews?  That usually indicates operator error, no?  And... you may want to mention how many strips!**
A: Good afternoon.  We cannot say for certain why folks have trouble with this product, but we suspect that more than operator error people may have tried to use the product for purposes other than it was intended and/or in applications for whit was not suited.  As for the strip count, that is 50.  We did not write the original description, otherwise we would have included that fact.  :)  - Water Test Kit Store

**Q: Can I use a chlorine neutralizer to remove chlorine from the test sample?**
A: I guess but it would be so little I don’t know how to accurately measure it.

### ⭐⭐⭐⭐⭐ Easy to use
*by C***R on August 31, 2023*

I bought a cheap ozonator online and was skeptical it actually worked. I bought these strips to test the water afterwards and it’s obvious the ozonator does not work. This test is great and easy to use, I will continue to use it to test out my new ozonator when it arrives.
