The Ultra-Clean Whole House Filter uses three stages of filtration to deliver purified water to your whole family. Perfect for either specialty filtration and/or extra filtration for that superb drinking quality water. Big Blue filter cartridges (20" x 4.5" aka Big Blue) and large 1" ports are used to reduce the pressure drop in any home. Our units come fully built and ready for installation.

So what makes these different than everyone else? Most competitors use a smaller filter cartridges (ex: 10" x 2.5") with smaller ports. Although these units may be fine for small homes or offices, they will not effectively remove all contaminants for larger homes that demand a high flow rate.

No happy with the system the system arrived without instruction and filters are not labeled I am not sure what they sent to me? Or what was installed? The system is not working properly, contacted customer service no help. I think if i install the filters in the correct order the system might work I am going to buy filter in a different company this company does not care or help customers this is my opinion

Great Product
Strong top bracket but when bracket is flush mounted to the wall and the system has water in it the bottom of the filters touch the wall. This does not affect performance at all just a quick note.

No stains and better tasting water
Excellent system - i installed it for the entire house and there are no more stains on the shower doors after the water dries. The chlorine taste is gone, the coffee tastes better etc.. I installed it myself - simple! I recommend it!

Big Boy Performs Well
I bought this big boy for clearing the sediments from my ground water.......It performs very well. I had to buy special string wound filters because my ground water has a lot of that iron in the water but it worked perfectly...Highly Recommended!!!
