Questions & Answers


have a filter wheuss cannot fine replacement

Asked by freddie November 3, 2020

I am not sure what the word "Wheuss" means, but I think you are asking about finding a replacement filter. HD has done this to me before... you buy a filter system and when you go back to the store for a replacement filter, HD either does not have the same brand or they guy in the store says you have to go on line. I went to HD's website and they have the entire Filtrete system at a cost that varies from $42 to $56, but no individual filters. There are 30 pages of filters to look though so it is possible that a filter that will work is available, but I do not know how to find out for sure that the filter you purchase will work. You might try the local HD store and see if the clerk can tell you for sure which filter to purchase.

Hello - Thank you for asking. This product is designed to be connected to the cold water line only.

It is the filtered water outlet line that gets connected to the separate sink faucet. The lower connection is the unfiltered water inlet line

Does this filter reduce TDS (total dissolved solids) in the water?

Great Filter
[This review was collected as part of a promotion.] I just installed this filter for a toilet bidet. Installed in under 30 minutes with the 3/8 inch supplies as stated on the box. If you have a 1/2 inch or something else, be sure to get the adapters. I would liked to of had white tubing and will change it later. I would recommend this product.

Compression fitting failed after four years
The filter has been very good at removing the bad taste from our tap water and the cartridges are easily changed. However, last week we came home after being gone three hours to a kitchen, dining room, breakfast nook, study, etc. (all with hardwood floors) flooded. The floor is ruined and repairs will likely run several thousand dollars. I inspected the failed fitting (I am an engineering laboratory director, one part of the lab is dedicated to mechanical failure analysis) and found the compression fitting ferrule--placed inside the tubing when assembling the compression fitting--was woefully undersized at .220" for .250" tubing. The fitting is clearly faulty, I'm embarrassed I didn't note this during assembly four years ago.

Glad That I purchased Water Fiktration System
A friend installed this under sink water Filtration system for me. It took him about 35 minutes. He said it was not difficult to install, but he wanted to make sure there were no leaks. My coffee and tea tadste better since he installed this system. My Boston Terrier drinks more water now, which is a good thing. I would like to get a filtration for my tub for bathing. This overall was a good purchase. I haven't had to change filter yet, but I'm sure it will be simple.

I highly recommend this filter!
I replaced the under-sink water filter that I've had for years with the Filtrete under-sink filter Model #3US-PS01. I highly recommend this Filtrete water filter!! What I did differently than the instructions was that I used a compression adapter (sold separately) on the cold water line that leads to my sink facet. That allowed me to connect the blue Filtete water tube directly to the "Input" side of the bracket from the cold water supply valve. I already had tubing from my drinking water filtration facet on top of my sink so I slid that same tubing into the "output" side of the mounting bracket. It worked like a charm! I now have great tasting filtered water available through the facet dispenser on top of my sink. I am a 63 year young female and the replacement took me less than 20 minutes.

Easy Install
I removed an Old-Westinghouse 2-can 0.5 micron filter system and replaced it with the Filtrete single can filter. I had a lot of trouble under the sink changing filters with the two can Westinghouse. I will not miss that! The Filtrete twist and remove filter is great. The $-cost-point is less than the 2-can filter and I still get a 0.5 micron filter for 6 months!! GREAT NEWS..

Absolutely love my Filtrete system!
I had a faucet mounted system in my kitchen that was good, but inconvenient. The filters were always needing changing and it was in the way (never mind the fact that there were several issues with the system's performance). Bought one of these and a friend installed it for me in less than 15 mins. Works wonderfully. Love it!

When I was a child, I HATED water. My mom would push it on me and it made me hate it even more. When I became a mommy, I became like my mother. But, with the Filtrete Proffesional Water Filtration System, my children LOVE drinking water. And so do I!!!!!!!
