Friendly reminder to remember to replace RO/DI filters

Not saying now is the time you need to, but if you can't remember when the last time you changed them now might be a good time. I changed out all my filters and my sediment filter looked more like a used coffee filter.

Filter group buy anyone ?????? ....

Hahaha... yeah, I didn't want to have to deal with group buys or any of that crap last time I needed filters and just bought a "multi-pack" where I got 5 of each filter + 3 DI resin filters cost me about $100 shipped to my door, its really one of those things that considering that'll last me maybe 2 years, I'm not going to be a cheap ass on this.

Just an idea, I jot down the replacement date on the cartridge with a sharpee.

We're blessed with pretty clean water in alameda, and I've been going over a year with no filter change. Is there any reason to replace the filters if the water tds is still 0?

 

[sfsuphysics]

well, there's an interesting article in reefkeeping.com about tds meters and accuracy that you should read

But sure your tds might read zero, but I dunno how your carbon filters would hold up to break down chlorine/chloramines. Those don't show up on a TDS meter, I can live with 10 TDS no problem, but chloramines? nuh uh.

Good point. Is it the charcoal or the DI resin or both that remove chloramines?
