Review: Seems to be a nice unit. Was simple to install. inclusion of some mounting screws would have been a nice touch. I installed it to filter bore water for my pool, so the install is a bit rough on my part but the unit seems to do the trick. Nice clean water coming through and no leaks from the housing. The ‘O’ ring is a little flimsy and could be more robust. Given the price it’s a pretty good unit. I am happy with it.
Review: Good unit installed easily in about 20 mins used brand name sharkbite fittings in PEX 3/4" line. No leaks use 13 wraps of teflon tape which was included. Even came with spare pressure relief valve (not sure if this is a good thing ;-( ) Will test to see if 5 micron filter is catching the gunk that I suspect and know is present in our community well water. The reason for the 4 star is the bracket supplied is a little flimsy. A simple change in their die forming process by adding wrinkle gussets would add rigidity in the 90 deg. bend.

## Questions & Answers

**Q: How do i buy spare o-rings? i want to buy extra o-rings for my simpure b07v6ry5b4 filter 10" x 2.5". the links in all the answers are not correct.**
A: O-Ring Replacements for SimPure DB1025 (B07V6RY5B4)  - Link： 
https://www.amazon.com/dp/B0B7P1L17K

**Q: Does this remove rust/iron?**
A: That would depend on the filter installed in the housing. 

If you are dealing with large rust and other sediment particles in your water you should be fine with a 5 micron sediment filter. For wells I like pleated filters like this: https://amazon.com/dp/B074FW96PG. 

If iron is dissolved in your water, you need something that filters iron/manganese like this: https://amazon.com/dp/B09JWP92PD

**Q: How do you contact customer support?  The inlet and outlet ports leak no matter how much ptfe tape or thread sealant used.**
A: I put an O-ring (# 18) inside each port before the brass bushing.  Then I coated the threads with sealant and 10 wraps of teflon tape.  I think there may be a design flaw, it shouldn't be that difficult.

**Q: The filter housing leaks profusely. i checked the o-ring/tested it without a filter to no avail. anyone had this problem and been able to fix it?**
A: Try to lube the o-ring with some coconut oil or silicone lube and reassemble.  Also, if you are using carbon filters, I have seen that sometimes they are just a bit too tall, and so removing one of the gaskets allows the tank to be tightened a bit further, causing a seal. If you write to the company for support, they have a support rep out of Canada who is fantastic.  Be sure to include your Amazon order number and you may want to request a call back (specifically by phone) so that they will route it to him early.

### ⭐⭐⭐⭐⭐ Review
*by L***H on 2 January 2026*

We have well water with heavy sediment/heavy iron. We have a 100 micron, jumbo, self flushing spin down sediment filter that is INCREDIBLY EFFECTIVE, then this canister with a 50 micron filter, then finally a standard size whole house with a 5 micron filter. Because our problem was at times extreme, this set up effectively corrected our issue. The spin down back washes every 3 days, this large cartridge we hose the filter once monthly, this has extended the life of the 5 micron to requiring a change about every three months. When we started, we had a standard spin down, with a 200 micron filter, going straight to a 5 micron. Both would clog anywhere between 2-4 weeks. The key was to increase the pre filters (spin down and canister) to jumbo sizes, and to make sure the initial spin down is back washed every few days, and your filter screen sizes are the correct micron. This is what worked for us, and we had a big issue. Hope this helps the next guy.
