3M SQC water filters

ChrisJ

I'm curious if anyone here is a dealer or works a lot with the self contained 3M water filters like the HF series etc.

I'm curious why an HF20-S for example is sold only for ice makers. HF20-MS is sold for coffee makers etc. If they're good for those products what's the reason they can't be used for drinking water? Obviously not exceeding their 1.5gpm ratings.

If there's some reason they aren't good enough does 3M have a cartridge that fits in the same housing as an HF20/25 for drinking water? I think it's a VH3 housing.

For example

One si 3 micron, the other is .5 micron. Might be some difference in the anti scale chemical too.

The HF20 is 0.5 micron and the HF25 is 1 micron I think. They both have carbon and should do fine for drinking water no?

It seems weird to me. If they make good ice and make good brewed beverages wouldn't they need to make good drinking water?

It's mainly marketing and having product segmentation. that filtered water is going directly into your drink in one form or another. It's a drinking water filter cartridge. Sometimes it has to do with not wanting to pay extra for the third-party certifications, but in this case it has all the certs for drinking water.

For models 3M have specifically for drinking water, they usually have it down to 0.2 microns like the 3MFF100. But how much filtration you want directly ties with how much you want to pay per cartridge. "Drinking water" filter cartridges usually cost much more, but also does filter more. Doesn't mean the ice maker filter cartridge isn't or can't be used as a drinking water filter cartridge.

If you clock the "27 product options" button in the link i posted it gives you a table comparing the different models. It seems less marketed to suggested applications in that table.
