Review: Great Value for Clean Water! - This filter housing is a reliable and affordable way to set up whole house water filtration. It was easy to install and works perfectly with standard filter cartridges. The quality seems great, ensuring clean water throughout my home!
Review: Clear vs. Blue - Seems like the only ones that are bursting are the clear ones, and leaks at the pipe connections on the blue ones. Put some pipe seal on threads, a good thread sealer, and should do the trick. I got the blue one.

## 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.

### ⭐⭐⭐⭐⭐ SimPure 10x4.5” filter housing
*by L***Y on February 2, 2026*

The SimPure whole house filter housing seems to be made very well. The reasons I chose it are that it is made of solid polypropylene and its design incorporates two o-rings. I did contact their support through email. I was interested in the size of the o-rings so I could have them on hand. They were quick to contact me with the information.
