If you are considering buying one don't hesitate absolutely love it.

Bought for of these, one for a friend for her DI and 3 for my rodi build. High quality and sturdy product!

I started off by purchasing one to add an extra DI filter to my systems. I was extremely impress with the quality and price of the canister, so much that i ended up by an additional one to add a ChlorPlus 10 Carbon Block Chloramines filter. The canister are high quality and do not see any blemish and they work like a charm. Thanks BRS for having all the parts to help me upgrade my RO/DI system. As well would like to thank you for all the information / videos you provided to make the an easy task. You have a customer for life.

Bought one to replace one of the stages on my RODI after an incident led to the original cracking, High Quality product with nothing to complain about.

As good or better quality than my big brand name RODI's factory canisters. No leaks, no blow-by. All components from BRS that should fit together nicely do so ( these, the screws, the shelves, the coupler pieces, etc) to make a nice looking, well functioning system that looks just as good as the factory built portion.

I added 2 more pre-filter stages to make my 5 stage a 7 stage - originally the system used (1) 0.5u sed filter and (1) 0.5u carbon block - The sed filters at 0.5u are expensive and clog quickly. The Carbon blocks - same thing, except if you let your carbon block become exhausted, your RO membrane can be damaged from Chlorine break thru.

I changed the setup to go thru (a) 5u Puritex Sed Filter, (b) 5u Matricx CTO carbon block, (c) 0.6u Puritex Sed Filter, (d) 0.5u Matrikx CTO carbon block.

Now the inexpensive 5u sed and carbon block stages take the brunt of sediment and chlorine, and I change them 3-4 times for each time I change the more expensive 0.6u/0.5u sed/carbon block filters, with the peace of mind of knowing that things are filtered before the booster pump and filtered better before they hit the RO, as well as having double carbon block filters to protect the dual membranes from devastating Chlorine.

Very solid and well built. I bought it to add a stage to my existing ro unit for chloramine removal.

This was a great can, and they helped me to decide what can to get based on my RO/DI System

I just have to say that if you want really high quality canisters or RO/DI systems (since I'm sure they use these canisters) then you can't go wrong with these. Be sure to order 4 screws for them though.

Where I went wrong was trying to get a cheap RO/DI filter system. I figured all those canisters were about the same. Yeah, that's not true. After about two months I awoke to find the bottom of my canister on the floor as it had cracked all the way around the o-ring. When I installed these cheap canisters two of them immediately leaked and I had to really wrench them down to get them to stop leaking around the seal. Of course this probably contributed to the one canister breaking. I can see stress fractures in the other one forming so I knew it was going to go soon. So just don't go to that cheap place on the internet and get junk filters. Start here at BRS.

I just got finished replacing the three canisters and it was so easy. Not one single leak at all period. I didn't have to wrench the canisters down at all. They are just hand tightened and not even as tight as I could go with them.

Another thing I noticed was that the o-ring that came with the BRS canister was a whole lot thicker than my cheap ones and it actually fits perfectly in the o-ring channel. On my cheap one I just noticed that the o-ring seems to be a little big in circumference for where it's supposed to go. No wonder it leaked. Again the BRS o-ring was perfect.

And the canister plastic on the BRS canister was clearer than the cheap one and looks higher quality than the cheap one.

And even the BRS screws were far higher quality and longer than the ones that came on the cheap ones. I think every corner that could have been cut on the cheap ones were cut.

And I bought replacement filters as well. I can also say that I like the BRS filters MUCH better. They also look to be much higher quality than the cheap ones. So basically the only thing I didn't replace is the RO membrane housing and the RO membrane. But I'm now thinking about replacing it. But so far I think it's okay.

So the moral of the story is that you really do get what you pay for. Go for the quality and stay away from the sites selling the cheap RO/DI systems. They do get you started, but you're going to replace them sooner rather than later. And pay more than you would have if you had just bought it from BRS to start with.

Oh, one last note... I bought some of the MUR-LOK fittings from BRS and they are much higher quality than my cheap ones and are even higher quality than the ones I picked up at Lowe's. With the MUR-LOK fittings I have to use a tool to pull the tubing out, but with the others I can just use my fingers to push up and pull the tubing out. So it makes me question how long they are going to hold compared to the MUR-LOK ones.

i am using this on my 60 gallon aquarium as a diy cerges co2 reactor. this item is very well built. plastic is nice and thick.

Connecting the murloc to it was easy as screwing anything else in, although when i got it tight enough the murloc broke and i was stuck with the male in the inlet. BRS does not sell just the lid so im suck buying another one. Wasnt too happy with that.

I bought this to make a kalk dispenser similar to the tunze. search around online for the diy on this. very beefy construction high quality product and all for about 14 bucks!

This canister works great for a media reactor. The large ports allow for lots of flow, and the clear plastic is ultra heavy duty. Compared to other manufacturers canisters, the clarity is better, the plastic is thicker, and the gasket lasts longer when properly lubricated. If you are looking for a replacement canister for a media reactor or RO system, you won't find better.

I bought one of these to add di to my existing ro unit. Works great and with the reusable cartridges you just have to replace the di resin.

High quality...Just what u need to add a extra stage to any RODI System

I purchased three of these to use as media reactors (granular carbon, granular ferric oxide and bio pellets). These are well built and the 1" ports allow for good water flow.

These canisters are made of excellent and clear quality material. The seal and ports are perfect. Bought three of these and upgraded my RO systems to RO/DI.

I used one of these to add a DI cartridge to my RO system and I've been very pleased. They are made of high quality materials and after months of use mine hasn't leaked at all

I added the canister for a DI canister to my RO and I'm now pumping 100% pure water

Simple and least expensive way to upgraded a RO system to RO/DI. It is a high quality canister that is easy to install. just make sure that you order the Refillable Cartridge with some extra tubing and 1/4 filttings that you may need.

I got this to run the Nuclear grade color resin and it was great since my RO/DI system is in the garage with good space to unscrew the cap for maintenance. However, I bought another one to run my active carbon and it's a pain to unscrew the cap in tight space in my cabinet.

These cartridges are great for upgrading, converting from water purifiers to air purifiers, co2 scrubbers, etc.

I turned it into a kalk reactor to help balance alk and it works greak.

This is a great way to upgrade your existing RO system. I had a 3 stage RO system without DI, with this product I was able to add DI without having to upgrade the entire system.
