how long the cartridges could be used in good function?

That will depend on the concentration of polutants in the air of the area where you are using them. For me, they last until I start feeling too much smell (in the air that I'm breathing) inside the mask or when I start caughing too much. It means the filters are already getting too dirty. Another thing you can do is check the colour of the filter in the inner side, the small hole where it attaches to the mask. If it starts getting dark, I think you might need to change them.

Hour wise I don't know but have used same cartridges for a dozen spray paint jobs with no evidence of saturation

Read the instructions that comes with the cartridge to verify this info....I think it says once an odor is detected, replace the cartridge. Also, when not in use, keep the cartridge in a airtight bag to prolong effective filtering.

Well I have use these for yrs. Now; how long do they last / Up to 40 hrs or a week. That depends on how they are used. When using oil base primmer block, about a week to ten days. But like I said it depends on use per-day & hrs.. When not in use remove filters put them in a ZIP-LOCK bag to prolong life. If you get new cartridges and don't use them you have about 5yr self life.

Depends, I do several mosquito treatments each day with a gas powered blower and pesticides. They typically last about to 2 to 4 weeks granted you seal up the cartridges while not in use (they are passive filters constantly working). Once I start to smell a little exhaust from my machine I know its time to change cartridges.

I've used my current set for 30-40 hrs working with wood. still can't smell wood with the mask on. It may depend on what you are breathing in. the activated carbon may saturate quicker with harsh chemicals

In a boat bilge with a fan blowing and applying 70% solvent coatings: about a half hour before mild breakthrough. Very much worth it. Once outside the bilge to change cartridges, it is evident even after breakthrough, I was still protected by these noxious vapors.

not very long. I used it once having found it too expensive to maintain. At the time one cartridge only gave a light fizz to the water - much less than a soda of any kind or of Perrier or other bottled water. I saw no reason to continue its use. At the time the lowest prices for cartridges was much higher than I see another person found.

I don't know. You'd have to ask the company selling the cartridges, not the customers.

1 year, I believe, butwith no movingparts, there's little to go wrong, unless the case were to split or crack. Just drain it well if you live in an area that experiences freezing temps. I'd also remove, clean & store the cartridge in those areas.

I'm still laughing about the answer from "Mike2so Silicon Valley Native". I don't think I'd want the ink cartridges after they are "all raped up"! I've kept them for up to a year (all wrapped up) without a problem.

The Products Shelf life is 2 Years. All our cartridges are newly made and sold within months. So the products you get will have at least a good 1 year and 9 months Shelf life.

I can not say exactly, buy the cartridges are ok. I had bad experience with only one of them

You should see a date on the carton for the cartridge. As long as you do not break the seal on the package it should stay good.

I've had mine over a year... no problems. Each cartridge is packed in a sealed plastic "bag" that it seems to me would greatly increase shelf life and prevent drying out... but they are also not "open" until you insert them into the machine so I suspect the shelf life is fairly long.

I believe they should work well. Amazon is very good about refunds if you find there is any problem. With a previous printer, I did some trouble with the remanufactured cartridges....they had an expiration date and thus the printer would not accept them but that was the only problem. Good Luck.

My package has no expiration date but I went away for more than a year and the cartridges were still good. Refrigerating would extend that eve more. You could call Epson if you really want to know.

Mine lasted 6 months(it depends how much you print). Keep printing even when the display tells you you need to replace the cartridge. You will know when to replace by the page appearance.

Will last a good 2 or 3 years before renewing, there great! the expiration date should be on the cartridge, mine is.....

It really depends on the cartridge type. I agree about going to the web site.

I don't know. Both of mine quit working before I could replace the cartridges.
