Pentek Filter Inline Carbon Filter
Drinking water filter housings come in different sizes and styles to hold a variety of water filters based on flow rate, connection size, and connection type.

Just What I Needed
These 10-inch Pentek enclosures are a perfect size for a whole house filter. It has 1" inlet/outlets but they are easily reduced down to 3/4" with a reducer or a bushing, if required. There is also a 3/4" inlet/outlet model but make sure that the prices are similar, because the price of this 1" model was much lower than 3/4" when I bought it.
I like these housing units and have two of them, but it can be a bit tricky to re-assemble after replacing the cartidge. I have found that it is essential to completely lubricate the o-ring and the threads, otherwise the seal is poor and there is a lot of leaking after the water is turned back on. I think in our case we have a lot of iron in the water, which adheres to the o-ring and makes it bind when screwing the blue housing back into the top part of the filter. If the o-ring becomes distorted, it does not seal well. The recommended silicone lubricant is expensive and hard to find. I have been using petroleum jelly (less than $2 for a big jar at any drug store) with no issues. For me at least, there was no need to lubricate on first use, as the o-ring was new and clean. But on two subsequent occasions when I tried to replace the filter cartridge and didn't bother to lubricate, I had a very difficult time getting it to re-seal. Lubrication resolves this difficulty completely.
10 years ago, installed a SEARS filter that looks the same, just not pretty blue.
Works fine. You have to use the little tube of grease that came with it on the rubber seal (just a thin coat) so that it doesn’t “bunch” the rubber up, causing it to leak.
