Lenses Technology:

✓ CR-39 Custom-Made Lenses

CR-39 is made by polymerization of diethyleneglycol bis allylcarbonate (ADC) in presence of diisopropyl peroxydicarbonate (IPP) initiator.
"CR-39" is an abbreviation of Columbia Resin 39. CR-39 has the highest Abbe value of any lens. An Abbe value defines the chromatic aberration of material, and this effect is generally more noticeable in peripheral vision than when looking through the center of a lens. Resin raw is injected into lenses mould. After that, the anti-scratch coating is applied.

  • Anti-scratch technology.
  • Unique colors, with over 4+ tests to achieve the final result.
  • Gradient colors with smooth transition.
  • All DE products have V-Groove (Removable Lenses - Technical feature that allows lenses to be removable, in order to add prescription etc)

+ Metal Parts.

Metal Core wire with IP plating that prevents oxidation and wear.

✓ 100% UV Protection.
The lenses we use, have a UV protective coating with maximum filtration against harmful sun rays.

✓ Lenses Category: 3.

The bigger the category number of lenses, the better. Category 3 in lenses, is considered better than categories 2 & 1. This is because they provide extra protection from both visible and UV light. These lenses allow less than 20% of visible light to penetrate the lens. This means that they will block out 80%+ of light. Category 3 lenses are considered some of the best lenses in the optical industry.

Acetate Technology:

✓ Italian (Mazzucchelli) Acetate.
Our Acetate Materials are coming from some of the biggest acetate factories in Europe. Fabricated from wood pulp and cotton.

Mazzucchelli 1849, is an Italian Company based in Castiglione Olona, and is a worldwide leader in the manufacturing and distribution of sheets made of Cellulose Acetate, polymer of natural origin, traditionally used in the production of optical and sunglass frames. Cellulose acetate is a modified natural polymer. To obtain Cellulose Acetate Mazzucchelli starts with the selection of renewable sources such as certain varieties of trees and cotton linters. From these sources the purest part of the cellulose is extracted which is subsequently treated with Acetic Anhydride and transformed into Cellulose Acetate powder.

✓ Engraved DE logo on the temples.
Every pair has the engraved logo, product name, and measurements on both temples.Comes with a luxury box, eco-leather case, and cleaning cloth.

Worth it!
Perfect fit for my 23 MDX, easy to install and great value for money. Dealership quoted me a ridiculous amount to replace the air filter. I would recommend everyone to DIY. Bought it together with the cabin air filter. Will definitely keep an eye on longevity. These are washable so probably wont need to buy for at least a couple years.

A Great Filter (Installed on a 2014 Acura RDX)
I installed this on a 2015 Acura RDX and it has been a fine replacement for the original air filter. The filter offers a good value and resembles the filter that it replaced and seems to be an equivalent replacement in every way. It fit into the housing perfectly and was just as easy to replace as the original filter was. The white color of the filter also makes it easy to see if an excess of dirt has built up on the filter. I'd recommend this filter. The materials are good, it offers equivalent functionality, and great value for the money.

Excellent quality and price
The picture above is of two different brand engine air filters. One is a Fram Extra Guard and the other is the KAX filter, which costs half as much. Can you tell which one is the cheaper KAX filter? There may be a difference in material that is not visible, but they feel and look the same. It seems like a safe bet to try out the KAX and see how well it performs/lasts.
