## Description

SimPure Upgrade Whole House Water Filter Housing, 20 Inch Big Blue Filter Housing, 4.5" x 20" Universal Size, 1 inch NPT Thread Inlet Outlet, Large Capacity, Heavy Duty Steel Mounting Bracket, 4 Screws, Wrench

Review: Fantastic - Fantastic 👌🏻, heavy duty , Well made and works efficiently; I liked the product and recommend it.
Review: Seems pretty good, used to filter bore water - 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.

## 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.
