You know it's important to change your filter when your "indicator lights up" or when your "TDS meter reads above 006ppm". With our automatic filter replenishment program, you can always have a filter on-hand and available when you need it. Avoid unnecessary trips to the store or overnight shipping charges!
Not sure what to order?
If you are unsure of how many filters to purchase we suggest a 4 pack every 120 days (which equals 1 filter a month).
You can adjust your auto subscription after this initial shipment should you need to.
ZeroWater filters are the only pour-through filters on the market that meet the FDA standards for TDS in purified bottled water and the only pour-through filters certified by the NSF to reduce lead. We use a patented, five-stage filtration technology to remove virtually all dissolved solids from your tap water.
