## Description

desertcart.com : Vantrue 40mm Ultra-Slim CPL Circular Polarizer Filter for Vantrue N4 Pro(S), N5(S),N4S, S1 Pro(MAX), N2X,E2, E1 Lite Dash Cam, Reduce Glare and Reflection, Enhance Contrast : Electronics

Review: High quality filter - This filter significantly reduces glare and reflections, enhancing the clarity and color saturation of my dash cam footage. Perfect for capturing clear views through the windshield. The ultra slim design fits my Vantrue Nexus 2x seamlessly without causing vignetting. Regarding the one star reviews mentioning image degradation and rainbows, I suspect these issues stem from not removing the protective plastic film on both sides of the filter. It’s easy to miss but crucial for optimal performance. Tip: Before use, carefully peel off the thin plastic film on both sides. Check under good light if unsure, to avoid any image issues. It took a bit of trial and error to get the rotation just right for maximum glare reduction, but once I did, the results were impressive. Overall, this filter is a great value and a must-have accessory for any dash cam user looking to improve their video quality. It won’t eliminate all reflections (e.g., from metal or in poor lighting), which might disappoint those with unrealistic expectations.
Review: Great for sunny days and glare. N4 PRO S - Item arrived fast with my purchase of a N4 PRO S. I removed both the inner and outer protective films and checked for lint and dust. Simply screwed it on and adjusted it left or right until the rainbow effect was gone. Reflective glare from the windshield is gone. Yet to use it in a sunny day, but time will tell. If the cap doesn't fit one way flip it over and try again. Its made to go over the lens, not inside the lens (I made this mistake). For those who say there's rainbow effects, it's possible due to the fact that if you have a window tint on your windshield it will cause this.... Or there is oil from your skin on the lens cover. So make sure you clean the lens AND the lens cover.

**Q: are you supposed to twist it to adjust once it's screwed on? I noticed 2 notches in the lens.**
A: Once tightened by hand, it can be rotated 360°. Clockwise is best as you look at the front of the cam. As ccw can unscrew the filter.

**Q: Why is there no filter for the N4?**
A: Dear customer,
Many thanks for your asking.
The lens diameter of this CPL is not fit for N4 dash cam. And the circular polarizer filter is our new design accessory products for E series and the latest N4 Pro dash cam. 
If more question, please contact us via support@vantrue.net.
Thank you!

### ⭐⭐⭐⭐⭐ Great for sunny days and glare. N4 PRO S

### ⭐⭐⭐⭐⭐ Stop those annoying reflections
*by L***S on September 21, 2025*

I have two Vantrue dashcams, and both have this circular polarizer. It is effective in reducing reflections of the dashboard, and increases the contrast of your videos on sunny days. This Vantrue polarizer threads onto the lens, just like the filters used on SLR cameras. The quality is comparable to those SLR filters. It fits the lens well, the threads are smooth and accurately cut. Rotating the filter to adjust it is smooth and easy; there is just enough friction to maintain its orientation on the camera.
