Magna 4.5 x 10 Triple High Flow Filter SystemThe one thing most filter housings have in common is that they are made in the Far East (usually China). Even the industry standard for Big Blue housings, Pentek, is no longer made in the USA. The fact that ours are Black and Grey tells you these are not just another Big Blue Filter System. These US Water Housings are made in the USA and backed with a Lifetime Warranty, which is the best in the business.
This is a Whole House Filter System for two filter cartridges for point-of-entry such as on the main water line into the home. If you have 1" plumbing, this is the filter for you. It is available with a number of different cartridges to address different water problems, such as:
Includes bracket, wrench, and screws.
NOTE: If you are unsure what type of filter would be best for your application, contact one of our Certified Water Specialists at 800-608-USWA or e-mail us at support@uswatersystems.com. Our experts are available 7 days a week from 8 AM until 11 PM EDT.

"No doubt this is truly a heavy duty and strong material system; I compared it to what I used to have, and the USWater Magna is totally superior, weights twice as much due to it's high quality material and the canisters material quality feels superior to others. Plus it's 100% made in the USA."

"I have never seen a system built as well as this. It is well heavy duty made. I am glad I bought the system I was going to buy something from Amazon I decided not to. I made my mind up and gave you guys a try I'm glad I did."

"I have used US water systems several times. All of there us made products are of excellent quality. Sales and technical departments both are staffed by very qualified people."

"The system was much larger and heavier than I thought, which speaks volumes to its build quality. The plastic filter housings are very heavy duty; I have great confidence that it will make it through the winter freeze. The system is installed into the incoming water line of a single wide 16x80 mobile home. I have experienced absolutely no pressure or flow loss. The water not only tastes better but smells better as well. I have the 20 micron, 5 micron, and then carbon block filter stack. Highly recommend!"
