RO/DI question

[thysrof]

When go you replace the filters on the RO unit. Their about 1 1/2 years old and i started with a 60 gal and upgraded to a 120 6 months ago.

Is it the amount of use type of answer?

What's a TDS meter?

What's a TDS meter?

Mike,
What's a TDS meter?

 

[sulcata1619]

Total Dissolved solids. I have one you use to get a reading. my system usually reads down around 2 ppm. Tap water is around 250. Once I get abouve 10 I change my filters. you are most likely due.

if you talk with arnold (apon) he can get you a decent discount maybe. I can pick them up for you in Feb at the swap. Or you could come to the swap also, even though you can't participate. You can see how a real frag swap is run.

Bob, I have a handheld TDS meter you can borrow to check your RO unit. LMK

Great place to pickup Replacement Filters and Membranes
I just replaced everything a few weeks back.

Guy, great site and great price. Thanks

I think I'll just go ahead and replace the parts considering their 1 1/2 years old.

I've got a Spectrapure Mpro-25. If i got it right I need the 10" Carbon and Sediment filters and the 1.8" x 12" TFC membrane.

Thanks,
Bob

Bob if you are replacing membrane, get the 75 gal/day filmtec one it blocks out 99% compare to the 100gal/day one which only block out 95%

Those are great prices. I think I paid 100 bones on my last membrane locally.
