iSpring HC12X2 1/4'' Water Filter Housing Clear for Reverse Osmosis System 2.5 Inch x 10 Inch Filters, Clear, Pack of 2 (Not a Replacement Part for RCC7 Series Models Sold Before March 2020)

Been using this for last 3 years and extremely happy with the quality of product. recently I noticed a water leak and when checking identified that the 1st stage filter has a crack on canister and needs replacement. The replacement I ordered was the latest version and did not fit properly, when I called customer care NICK went above and beyond to offer the required help and fix my issue. Huge shoutout to the great customer service experience I had.

I wanted all three of my iSpring filter housings to be translucent purple, so I purchased these to match my RCC1UP reverse osmosis unit. When they arrived, they would not screw onto my system so I sent a message via email to Brian at iSpring. Turns out there are two different “thread” types on these canisters, coarse and fine tread. THE `PTK’ TYPE HAS THE COARSE THREAD, AND THE `AO’ TYPE HAVE FINE THREAD. For what ever reason, I got the wrong set to fit my reverse osmosis unit and Brian went way overboard helping me! He asked me to send him a picture of the type I had received and a picture of the top of the filter housing on my reverse osmosis unit and confirmed I had the wrong type to fit my iSpring RCC1UP-AK system. He then promptly sent out the correct Pair of filter housings along with a couple other Small parts to complete my installation of my 2nd iSpring reverse osmosis unit. I can not say enough on how wonderful the customer service center is. I want to call them the customer CARE team, because that is what they do. They do care! I’ve owned my business for 34 years, and sometimes staying in business is all about the service you provide your customer base after the sale is made. And trust me, Brian is a master at helping the customer with their needs or concerns. He flawlessly addressed the issues I had and sent out the stuff I needed to finish the job. Their products are top notch quality and the service they provide even after the sale is most impressive. I haven’t seen this in such a long time, the great attitude and friendliness poured out into emails and even on the phone when I called and spoke with Don. God bless this company and the great employee’s that make this company work!

Bought this to replace current rodi containers but when I screwed them on tight, it would leak everywhere. Unscrewed, took part complete rodi system to put the new tops that came with the container and put it back together. It worked perfectly like how it was supposed to work. So my advice is just take the extra time to place the whole top and bottom in order for it to work properly.

good

I almost didn't buy these and I'm so glad I did. I have a Coralife Pure-Flo II 50 GPD RO/DI system for my freshwater aquariums and I just cracked my 3rd canister. There's a serious design flaw in the Coralife canisters that leaves them weak at the base of the threads. Just lookin at one funny is nearly enough to crack one and you really have to crank them down to get a good seal, putting additional strain on an already weak area. I ordered yet another replacement before seeing these. Two complete setups for the price of a single bare Coralife canister. Figured they couldn't possibly be any worse and I'd get two, so I promptly canceled and ordered these which also had the added benefit of Prime Shipping.I expected these to be a knockoff and a direct fit for the existing tops. Not even close. Every inch of these is superior to the Coralife, from the cap to the canister. The caps have more meat, the threaded portion of the canister is thicker and it has a larger o-ring at the seal. Once I saw the difference, I installed both and plan on picking up another. The inlet and outlet fittings are a 1-1 match and the mounting holes matched up perfectly. The only caveat to replacing your Pure-Flo canisters with these is the DI cartridge. The large white seal washer on top is too thick to allow the canister to screw all the way down. Thankfully they pop out and a had a random o-ring with the same ID as the OEM washer and a wall thickness slightly more than the depth of the recess for the washer. The way the top caps on these are designed, they have an inside beveled sleeve around the outlet stem that protrudes further than the OEM Coralife. Using the o-ring allowed me to still get a good seal at the top of the cartridge and screw the canister down tight. If you're not a hoarder of random parts, your best bet is to probably take the cartridge to Ace or someplace else that has a wide assortment of loose o-ring and try till you find the right one. I'd post the dimensions but I'm already making water. Superior product for half the price. What more can be said.

After running the ispring reverse Osmosis filter (which I installed in 2014) with greatly improved water quality and taste for 9 years, last year I replaced the white cylinders with clear blue tint cylinders as it allows you to especially see stage one paper filter condition from the outside. Wanted to give Sean a mention for all the support he's provided over the years including recent replacement and upgrade of the flow control valve seen in the middle of the 3rd pic w/red feed tube connected. Long terms support by ispring has been exceptional and much appreciated over the years.

Bought this to replace a cracked unit on my RO unit. Unfortunately, although the unit numbers seemed to match, the canister was a different size and threading than the originals. Simple enough to replace the top and the canister on the original three filter unit. So all is now good. Does seem to be good quality, and hopefully won't crack like the original.

Photos show the finer threads (about 5ish rows of threads, possibly called the AO version). Received the coarse thread version (PTK or something?). Anywho, it wouldn’t fit so I took the whole unit apart to swap out the white top part, but while doing so the cheap little plastic connector (double male ends) broke in half… can’t figure out where to buy a replacement. Seems like parts will continue to fail anyway so I guess I’m just going to buy a whole new system =/
