I spoke to Brondell and asked if they need to be changed every 6 months when the red light on the reverse osmosis faucet comes on. I was told that I could monitor the TDS to see if the number is still low and if it is, simply unplug and reinsert the battery from the faucet to reset the light. We use less than 2 gallons a day so changing every 6 months is not necessary even with the amount of calcium/lime in our water. I would like to be a little closer to the distillate but the low TDS is acceptable and the water tastes great. The cost per gallon will be even cheaper as we expand usage. And the joy of not having to lug around liters of water from the supermarket is indescribable! Thank you Brondell for helping us save more money!
