Best Industrial Process Filter Housings of 2025

"I upgraded to a Dual BB system with a sediment pre-filter and a carbon block main, and so far, it's working great. The Pentek R30-20BB pleated filter is supposed to be reusable, and I haven't had to rinse it yet. I did notice a slight sulfur smell in the water, but I pulled the pre-filter and it was clear it was doing its job."

"I purchased this filter housing to complete my sediment filtration setup with three BB housings. It matches perfectly with my previous ones. I have total confidence in this company's housing to avoid any flooding issues."

"I bought this as a pre-filter for my Aquasana EQ-1000. The installation was straightforward, and I didn't notice any loss in pressure after everything was connected. Just make sure to use plumbing tape on the threads!"

"This is my first whole house water filtration system. I chose the smaller 10” model. After just 18 days of use in our mobile home, I can see how much sediment it's trapping. The filters were pure white before use, and now they show significant sediment. I decided to install this filter after seeing how much buildup was in my water heater. I highly recommend this filter for its reasonable price and effectiveness!"

"I appreciate that this unit seems well-constructed. Once I installed it, there was no noticeable decrease in pressure or flow. I used a male pex nipple on both sides, which made the installation easier. Just be sure to have it straight when starting, and use plenty of tape for sealing."

"I love that this filter comes with everything I needed for installation, including a mounting bracket and a filter wrench. The process was straightforward, and I experienced no leaks. I would definitely consider purchasing this product again."

"I needed a Big Blue housing for my project and was pleasantly surprised to find the Pentek brand still available. The quality is impressive, reminiscent of the Pen Pure days. I appreciate the lightly lubed o-ring and the attention to detail, which shows that the manufacturer cares. Overall, I’m a satisfied Pentek/Pentair Big Blue customer, giving this product 5 stars!"

"I’ve used this housing as a pre-filter for my RV and love its sturdy build. The plastic threads allow for secure brass fittings, and while I can’t speak to high-pressure durability, the housing has held up well under my setup. Just a note: it’s not UV resistant, so I keep it shaded."

"Having installed two of these in series for whole-house filtering, I was glad to find them still available after over a decade. The quality seems unchanged, which is rare nowadays. I recommend using a little food-grade silicone for the o-ring during installation for easy filter swaps. Overall, these are a cost-effective solution!"

"I needed a solution for sediment issues in my well water. After trying another brand with a slow leak, I decided to order this well-constructed filter housing. It features a clear canister that allows me to easily monitor the filter. After installation, I've run water through it and noticed no issues after three weeks. My water is now clear and sediment-free."

"I appreciate the heavy-duty design of these two Pentek housings I ordered. They fit perfectly in my existing setup without requiring any adjustments. Although I had hoped for better packaging during shipping, the construction quality is solid. I feel confident in their ability to last longer without leaking, especially since they match the spacing of my old units perfectly."

"I’ve been using these filters as pre-filters for my well and have been really pleased. They use inexpensive filters, which is a huge plus compared to other brands that require costly replacements. I can change the filters frequently without breaking the bank, and these have proven to be high-quality and reliable."

"I've had no leaks at all after installation. I only used thick BLUE Teflon tape and made sure to hand tighten it properly. It's been two weeks now, and everything is still perfect."

"I opted for this clear canister housing to replace my old system. It’s fantastic because I can easily see when it’s time to change the filter. Plus, at just under $16, it’s a great deal!"

"I use these for my RO system in my motor home, and they do a great job. One holds a prefilter at the spigot, and three more hold filters ahead of the membranes. It's fantastic to see what’s happening inside without needing to open them. The water in RV parks can be like playing roulette with my system! These housings make monitoring for filter changes effortless."

"With over 50 years of experience installing various water filter systems, I can confidently say this is the best I've encountered. It's designed for either permanent mounting or installation with copper pipe. The clear plastic housing makes it so much easier to see when the filter needs changing."

"Even though this was a 'used' product from Amazon, it looks and functions as if it were brand new. I'm very satisfied with the quality!"

"I installed the filter, and it works just great. There are no leaks, and the filter fits perfectly."

"I found this filter housing to be compact and just what I needed. I even created a 3-D CAD model of it for others on GrabCad."

"I purchased this product to replace my old sump that had a crack. It works just fine and meets my expectations."

"I used two of these to create a two-stage under-sink water filter system. The proprietary filters from my previous system were ridiculously expensive, and after a leak ruined my cabinet and flooring, I decided to switch. I mounted the Pentek filter housings easily using a 2x4. Initially, I faced issues with leaking relief valves, but with some adjustments and Magic Lube, everything worked perfectly. Now, after seven months, there are no leaks, and I enjoy great-tasting water!"

"I installed this filter in about 45 minutes. It's located under my kitchen sink, filtering cold water for drinking. I didn't need to mount it on the wall; it just sits in an old glass container. Be sure to have lead-free brass couplers and food-grade silicone grease on hand for installation. This grease worked wonders for the O-ring and helped seal connections without any cross-threading issues!"

"I set up this housing for a post-Reverse Osmosis De-Ionization Filter. It was incredibly easy to mount, taking only about five minutes. I’ve had no leaks since installation, and it appears to be made of high-quality materials. Although it doesn't come with fittings or filter canisters, I find it to be a good option for adding an in-line filter. I would definitely purchase this again if needed!"

"I appreciate that there are no leaks with this product."

"It fits standard 10 inch filters perfectly."

"I find it helpful to easily see when it's time to change the sediment filter."

"It's great to know that it's made in Taiwan."

"I bought this to connect to metallic pipe threads. The brass inserts worked well with proper care, unlike other plastic units that leaked or broke."

"I had to return my unit because it leaked from the 3/4” brass connections, despite my attempts to fix it. After re-installing multiple times, I switched to a more reputable brand that worked perfectly."

"This filter housing fit well, and after a quick adjustment, it has been leak-free. It's rated for 90 psi, which is great for my setup. I'm very satisfied with the purchase!"
