DUPONT FILMTEC™ XLE PRO-2540 Low Energy Brackish Water Reverse Osmosis Membrane Element

FILMTEC XLE PRO-2540 Elements offer better system performance and economics for small commercial systems by operating at very low applied pressure. DUPONT DOW FILMTEC XLE PRO-2540 elements are tape-wrapped, built with the same high quality membranes and materials of construction as industrial elements, except for the hard outershell, and are more economical for commercial systems with one or two elements per housing. It may be cleaned over a wide pH range (pH 1-13) for the most effective cleaning. In addition to high quality water and low energy costs, FILMTEC membranes also deliver savings by providing long lasting and reliable performance.

FILMTEC Brackish Water Reverse Osmosis Elements can separate salts from water and are produced with an automated fabrication process for precision, consistency, and reliability. FILMTEC RO membranes build on a tradition of leadership in the thin-film composite membrane industry and meet the challenges of higher rejection in lower-pressure operations.

DOW and Dupont merged and DOW FilmTec membranes are now sold as DUPONT FilmTec. FilmTec XLE-2540 membrane element has been discontinued by the manufacturer. XLE PRO-2540 is the direct replacement.

Comfortable
Color: Black,navy,burgundy,brown, Size: Medium
I have had a lifetime of different briefs, some name brand, some generic. I am 165 lbs, wear Medium, and these are closest to feeling commando of anything I’ve ever worn. Comfortable, not too tight waist and legs, and yes silky touch yet not slinky. Maybe not for support wear, but casual and cool comfort, the “Cat’s meow”. I just came on to order some more

Great fabric - pouch too small!
Color: Black, Size: X-Large
First, the fabric used is wonderfully soft and comfortable. It;s the first thing noticed when package was opened. Strange, but the elastic waistband is about 1/2", very similar to a woman's style panty. But it's comfortable and easily acceptable. The main problem is that the pouch that holds your "stuff" in place, is oddly and unnaturally small. Small enough where this average man's "stuff" tends to fall out of the pouch on one side or the other. I sleep in my underwear, and every time I did with these, I awoke with the front pouch off to the side and everything down there was hanging outside of the underwear. They also seem to do well through a wash cycle. However, if the main reason for wearing underwear is to keep your stuff in place, these fail from the beginning. I ordered another brand from overseas, and they had the exact same problems as these! I wonder if that's just how they make them outside of the USA. The Bottom Line? Uncle Steve Disapproved!

Premium cotton underwear at a modest price. Highly recommend!
Color: Multicolora6-4 Pack, Size: X-Large
Bought my husband 2 variety packs of these, and they are still great over 2 years in. High quality cotton briefs are breathable, colors are vibrant, and the fit is spot on. A good value at this price point compared to designer brands, and the product overall exceeds expectations in terms of comfort level, durability and appearance.

Comfort, Support, and Quality – The Perfect Boxer Briefs
Color: White, Size: X-Large
These men’s boxer briefs are everything I look for in everyday underwear. The fit is excellent — snug where it needs to be without feeling restrictive, and the fabric has just the right amount of stretch for all-day comfort. The material is soft, breathable, and holds up great after multiple washes. No fading, no sagging, and most importantly — no riding up. The waistband is strong yet comfortable, staying in place without digging into the skin. What really stands out is how well they balance support and freedom of movement. Whether I’m working out, at the office, or just relaxing at home, these boxer briefs stay comfortable and keep everything in place. Great value for the price and a dependable choice for everyday wear. I’ll definitely be buying more. Highly recommend!
