Easy installation and well built product. Like the double o-ring set up. Also like that the replacement filters are easy to find. I'm a plumber and I will recommend.

If you're looking for a whole house filter, this is it ! Installation isn't easy but it isn't terribly difficult either. Total time for me was about 7 hours (including one extra trip to the hardware store) but could have been a lot less. First the bad news... I had two leaks ( a fitting and the o-ring seal). However, both of these turned out to be operator error and were easily taken care of. Also, the bracket comes with screws to mount onto the filter housing, but not to mount the bracket to a wall so be aware of this. Second the good news... I love this filter system. It wasn't terribly difficult to install. As you can see, I included a by-pass so that I can change the filters without shutting off water to the house. This housing unit is compatible with any filter that is 10x4.5" so you can easily choose the filter that suites your particular application. I would recommend getting a spare filter, so that you already have one when it's time to change. As for changing the filter, there is no indicator (I actually like this because no batteries or electricity is required). To know when to change, check your last year's water bill and estimate time based on water usage and filter capacity. In short, if you need or want a whole house water filter, this is a great buy for the money ! Highly recommended !

I’ve had this filter installed on my well for almost 2 years and change the filters every 3 months. Other reviews talk about a leak from the pressure release valve but I have not had that issue. The only issue I run into is trying to break the housing loose with the supplied wrench. The handle is really short and doesn’t give you much leverage. Other than that I highly recommend this.

I purchased and installed this unit in March 2021 with no difficulties. It filters the water just fine with my filter choice. Now for the problem, and it's on me for not paying attention. I ordered the SimPure DB10P and assumed that is what I received. I change the filter regularly and today, 23 August 2024, during my filter change I noticed my o-ring is out of tolerance and had to drop it in the freezer to shrink it a bit to ensure a good seal. I went on Amazon to order a new seal and to my dismay I saw my model housing should require two o-rings and the inlet and outlet ports should have brass fittings installed from the factory. Mine had neither, meaning I was sent a DB10 NOT a DB10P. Like I said the filter functions fine but it's not what I paid for.

This filter is awesome. It has (2) O-rings in it so it does not leak. YOu dont have to tighten the crap out of it to get a good seal. That is the most important point as I have tried others. I think that this will be my last filter unit because it is built to last.

Great price. I've installed these in 3 homes of my family. They work great as a whole house water filter.

It took me about ten minutes to regret purchasing this piece of junk. As other reviews note, the pressure relief valve leaks no matter what -- and the manufacturer obviously knows it is a problem, because they send a replacement relief valve kit with it! I spent more on fittings than I spent on this canister, and wasted considerable time doing the install, only to find that this thing is incapable of containing water. I highly recommend that you buy something else. I'll be tearing this down, returning it, and searching for another product -- probably locally, since this kind of low quality bad experience is becoming par for the course for things purchased through Amazon. EDIT: I am updating this review due to the continuous contact I have had from the seller since I submitted it. First, they offered to "address any issues or concerns," and to "work to resolve the issues." That was useless, as I had already processed the return and refund through Amazon. Plus, there is no way to address or resolve a water filter housing which is incapable of containing water. Second, the following day, they contacted me again and offered to replace the product by sending me a "backup." It was unclear whether this would be free or at my cost, but in either case, I was not interested and did not respond. They offered to "meet my requirements" to "solve this issue with a wonderful ending," which I suppose means that I could have demanded something in return for editing or deleting my negative review. As noted, I did not respond. Third, a week later, I was again contacted, this time purportedly to discuss why I was returning the housing as an "unwanted item." The message from SimPure implied that I didn't want it because "it didn't meet my needs," to gather information to correct anything "inaccurate on the product detail page." I did not appreciate the implication that I returned the item because it did not meet my need. It was exactly what I needed -- or would have been, if it had the ability to contain water without leaking. I suppose if there is an inaccuracy on the product page, it is the statement that this plastic bucket will hold water and not leak. Although never stated (to avoid violating Amazon policy), it always seemed obvious that SimPure was fishing for a way to make me retract or at least tone down my negative review. Ultimately, all they accomplished was this edit -- my first ever in nearly 20 years of using Amazon -- to reflect an even more negative experience than originally experienced. In the end, I bought an AO Smith filter housing locally at the big box store, at a lower cost -- along with a couple of filter cartridges. That item installed easily and didn't leak a drop -- leaving me far more satisfied than SimPure's product and barrage of communications.
