Tools and Hardware Reviews of 3M Filtrete 3US-PS01 Under-Sink Advanced Water Filtration SystemCustomer Review: Flow is very slow. I do not recommend it. Summary: 1 Stars
I purchased this filter with high expectations. However, I am very disappointed because of the slow flow. After 3 weeks, it start running very slow. I feel like I spend over $50 for nothing. I do not recommend this product.
Customer Review: Good and convenient filter for Houston, TX Summary: 4 Stars
I am from the Northwest and was spoiled by the pure water up there. When I moved to Texas the tap water gave me headaches and stomach problems, so I started buying bottled water jugs (Ozarka Spring water). This solved the problem but is expensive (more than $1/gallon) and uses a lot of plastic. I bought the Filtrete system and installed it. The cost per gallon is about 1 cent, which is awesome. The quality is not quite as good as Ozarka Spring Water, but I feel better about not using so much plastic and importing someone else's ground water that should probably stay in the ground there.
I will say the Filtrete installation may not be as easy as the instructions make it out to be. If you have standard stems (where the water comes out), it's very easy and intuitive. But I had a flared stem and the compression fitting that comes with the system did not work. I spent an hour trying to modify the plastic bits before I realized I just needed to buy an adapter at the hardware store. $3 later I had a connector with a flare fitting on one side and the standard straight fitting on the other. The filtrete hose than connected in just a minute.
Be sure when you are tightening the nut for the compression fitting at the input hose (where the water comes out of the wall and goes into the first blue tubing for your filter) that you keep pushing the plastic tube into the fitting while you are tightening the fitting tightly. I used a wrench to tighten it well, but you could use pliers. This is important because if you don't keep pushing it into the fitting or if you only hand-tighten the tube will get pushed out of the fitting when tightening, or will leak. So remember: hand-tighten the fitting that goes to the faucet (the output), but wrench tighten the fitting that comes from the wall (the input).
All in all, the quality of the water is good. There is a fishy smell to tap water in Houston and it deals with this nicely. The taste is not quite as good as the Ozarka spring water, but is definitely better than the tap water. It's hard to beat ground water. But for the money, this is a very respectable unit.
It's also convenient. The flow is labeled as 1.5 gpm, and I believe it. The flow rate is great where I am (fairly high pressure area). I could it use it for washing if I wanted to and I can certainly use it to fill a pot of water for cooking pasta. This is much more convenient than the Pur water filter which has a severely reduced flow when filtering. Also, I read many reviews where people said the Pur system was very flimsy and leaked easily. That's primarily why I went with the under-the-sink Filtrete system. Also, the Filtrete is suggested by the National Science Foundation for water filtration, which I liked.
Replacement every 6 months is a deal as well since the Brita system requires constant filling and replacement every 2 months. And the filters are very reasonably priced considering the volume of water they can handle. As I said, about 1 penny per gallon for me.
I highly recommend this system. I only gave it 4 stars because I needed to buy a different compression fitting and because the flavor of the water is not absolutely perfect (it's very good, but doesn't beat ground water). The instructions should have mentioned what to do with a flared stem end, at the very least.
Customer Review: Great unit for price Summary: 5 Stars
We've been using this filter system for over two years with absolutely no leaks in the fittings and excellent water flow whether using the standard filter or the pro model. Would definitely recommend for any DIY'er, or even those first time installers.
Customer Review: Great water filter for our kitchen sink Summary: 5 Stars
We remodeled part of our kitchen, and I had to select a water filter for underneath our kitchen sink. I did not connect this to the main sink faucet; I bought a separate faucet just for filtered water (not included.)
The 3US-PS01 was my cheapest option, and it exceeded my expectations. It has a much higher flow rate than my refrigerator's water filter. I've had it for three months, and the water still flows fast and tastes good. I plan to replace the filter every six months, per the manufacturer recommendation.
Customer Review: Great, easy filter Summary: 5 Stars
This filter is a snap to install and does a great job filtering water. If there's any drawback at all, it filters the water TOO well. The filtered water tastes "soft," rather more like distilled water than drinking water. It's a vast improvement over untreated Phoenix city tap water.
