How to determine whether an UV lamp is an “ozone type”?

How To Spot An “Ozone-Type” UV Lamp At A Glance? Two Simple Steps!

Choosing a UV light sanitizer is like choosing a “bodyguard”? The key is to know whether it “releases toxic gas” (produces ozone). Want to know which type yours is? Don't worry, here are two foolproof methods:

First Method: Check The Lamp Tube's Spectral Marking

1. Check The Wavelength Specifications:  

If it says “185nm + 253.7nm,” congratulations—it's an “ozone-type” expert! Why? The 185nm “secret weapon” activates air to produce ozone, achieving thorough disinfection with no blind spots.  

If it only says “253.7nm,” it's a definite “non-ozone-type” member! The secret formula? These lamps add special elements (such as titanium and cerium) to precisely filter out 185nm light, ensuring safety and peace of mind.  

2. Check The Product Model Letters:  

If the model ends with the letter “Y” (e.g., UVY), it's the exclusive mark of an “ozone-type” ultraviolet light sanitizer!  

If the model ends with the letter “W” (e.g., UVW), it's the safety certification mark of a “non-ozone-type” ultraviolet light !

Tip: Next time you purchase one, remember to check the back of the lamp tube!  

Second Tip: Verify During Use  

After disinfection, do you smell a fresh “grass-like odor” or “post-rain scent”? This means the “ozone-type” has been at work!  

No special odor after disinfection? This is undoubtedly the “ozone-free type” at work! Ventilation? Not needed! You can enter the room immediately after turning off the light.

Important Safety Tip: If it's confirmed to be an “ozone-type” model, make sure to open the windows and ventilate for at least 30 minutes after use! Avoid irritating your respiratory tract!

Conclusion

  “Check the wavelength, recognize the letters, smell the odor, ensure safety” — easily distinguish UV sanitizer light types and disinfect safely without any pitfalls! Next time you choose a lamp, you'll be an expert too!
