How do I know when filters/cartridges need to be replaced? It has been a year and my TDS reads 3. My tap is 275. Do I wait for it to go bad?

Yup, just wait for it to go above 5 or 6. If you don't use your RO constantly, you get a little more life out of the filters. Yours prefilters generally need to be replaced every 6 months, and your DI resin every year, but then again if your TDS isn't lying I would just wait until it tells you to change em.
