Reverse osmosis has air bubbles

That is common, you are forcing water molecules under 50-60 psi pressure through a piece of plastic film with 0.0001 micon pores or holes in it.
No the air should not affect the DI life.
What is your tap TDS, RO only TDS and final RO/DI TDS? What is your exact measured waste ratio? What is your water pressure, water temperature and calcium carbonate hardness? Do you know if you have CO2 in your water or if not do you know your waters pH and alkalinity? These two numbers are used to calculate the CO2 content and CO2 is rough on DI resins.
What DI resin are you using, is it factory fresh or bulk resin, if bulk was it stored properly and is the cartridge packed tightly? Horizontal DI or vertical DI?

My tds output is 2ppm. The tap water is usually 150ppm more or less. Its a vertical deion housing.
The resin is bulk from jlaquatics.
Im not talking small bubbles that stick to the walls of the tube but big ones that travel through the pipe. Thats normal still?

The ratio is 1 to 3.5
I use the ro/di but its not hooked up permanenty. It sits in the storage room with water in it and i hook it up to the tap with a faucet adaptor when i need it.
I dont know about the water pressure or temp. The temp is cold.
So its 160 in 2 out and after deion it never changed.

What is the RO only TDS without the DI? This is the important number.
As far as the air, you may have air trapped in the housings since you use it portable. Next time you hook it up, once it is under pressure pick the unit up in your hands and slowly rotate it around in all orientations to release any trapped air in the housings and canisters, it should burp it and reduce the air bubbles once it has all been released.
You say the resin is bulk, how much do you buy and once opened do you use a seal a meal or other vacuum device to reseal the bags so the resin stays moist then store it in the back of the refrigerator so it stays fresh? Even under perfect conditions, resin has a shelf life of about 6 months. Once it has been opened this goes down and if it is allowed to dry out or is exposed to warm conditions and bright lighting it exhausts very quickly. Once it is dey it loses its cation and anion electrical properties and is shot. Itell people never buy more than you can use in 3 months time and if possible divy it up in individual 20 oz. portions in vacuum sealed bags so you don't have to open it each time and expose it all. I used to buy bulk resin but could never ever get the life out of it I get out of Spectrapure MaxCap and SilicaBuster cartridges. My DI life went from 150 measured gallons to 830 measured gallons on my very first swap and its been over 1000 gallons out of a MaxCap and 3000 out of the downstream SilicaBuster ever since. And I was buying the best resins available directly from Resin Depot and major suppliers in sealed 50 lb bags which my reef club then split up into individual portions.

The ro only is 2ppm. Its good i think. Ill try abd rotate it, and see what happens.
For the resin, its sealed in a shiny bag and i use all of it at once. So none is left to go bad. It should be in the refrigerator? I didnt know it had a 6 month shelf life. It was probably sitting there longer before i used it.
Thanks for your help, and i may use maxcap deionization resin.
The MaxCap cartridge is not to be used in a single DI system, it is designed as a roughing filter or pre DI to be placed in front of a second DI. The best combination is the MaxCap followed by a SilicaBuster and for single DI applications the SilicaBuster is the best bet.
Due to the way they layer or stratify their resins, they are not a homogenous blend, they do not sell bulk refills. You buy a new cartridge each time. You can see how they are layered in their photos. I was told they do this to take advantage of pH and other changes within the resin bed and is something they have learned in their years of research and bench testing of resins in their lab. This is one of the things that make their resins unique and helps them last longer and roduce true 18.2 megaohm resistivity pure water.
