Aquasafe Ro/di unit

[christyf5]

I change the filters (poly, carbon and whatever comes after the carbon) every 6 months or so. Sometimes more often in the winter as some stuff comes through in the water after a good rain and they can get really gross and brown. I usually changed out the DI then as well for good measure. I have a clear canister for DI now so I change it out closer to a year or when it looks really orange. I changed out my RO filter after about 2 years or so, mostly because they were on sale and I figured why not. It was still reading 0-1 TDS though. My current RO filter is nearing the 2 year mark and I have no plans to change it unless the TDS increases.
