When is it time to change the filters? The TDS Meter is reading 035 (ppm, I assume).

On average, sediment and carbon filters get changed every 6-8 months, DI resin anywhere from 8-12 months and RO membrane about every 2 years. It all depends on the quality of the source water and amount of water processed.
Something needs to be changed with the TDS at 35.

Tucson water quality is so poor, that I wouldn't change mine until it got to be around 50. My tap water comes out at 400+.
Most people like to keep their TDS below 10 though.

I did something different after posting - namely, had the RO/DI output directly in a clean glass - and it tested at 001... so I guess that means the big bucket that I've been using for the past year should probably be cleaned... still, I'm going to follow cc's advice and get new carbon & sediment filters (if I can figure out which ones they are...)

Do you use the same bucket to make salt water? If so that could be why the reading is different.

Piggy, I used the bucket to hold about 20 gallons of saltwater when I changed from the acrylic to glass tank... ergo, erroneous reading...
