Urth 40.5mm UV + Circular Polarizing (CPL) Lens Filter Kit  
The Duet Filter Kit includes a UV filter to protect your lens and make your photos sharper, and a CPL Polarizing filter to reduce glare and enhance colours and contrast.  The Duet Filter Kit combines two bestsellers in one compact stack perfect for light travel.


The kit includes the UV Lens Filter, which reduces ultraviolet light to make your photos sharper and protect against scratches, oil, dirt, fingerprints and salt water. It also includes the CPL Lens Filter, which reduces 99.9% of reflected light for better contrast and stronger colour saturation.


All our filter sets come with lens filter caps for compact and safe storage, a recycled cleaning cloth and in recycled plastic free packaging.


Japanese AGC glass
High quality Japanese AGC glass features an 8 layer nano coating for improved sharpness, extra protection and easier cleaning.


Ultra slim magnalium edge
The deliberately designed ultra slim edge prevents vignetting and our durable magnalium has a lifetime guarantee.


Double thread
All filters have a double thread for stacking filters or using screw caps.


Positive impact
Urth's goal is to have a lasting positive impact on the planet. 
By consciously designing products that help people engage with nature and planting 1 tree for every product. Urth's mission is to plant 1 billion trees by 2032.


Conscious design
There is a constant search for ways to minimise the negative impact on the planet we love. When new products are made, low impact materials are sought and designs are refined to minimise waste. All packaging is redesigned to remove all plastic, use recycled materials and ensure they are recyclable too. ,

Sharper photos, reduces UV light for sharper images. 
Better colour saturation, cuts off polarised light for more contrast and vibrancy. 
Two filters in one kit. with two essential filters.
