DuPure's proprietary water filters can be expensive. We offer high-quality compatible RO filters, membranes, and parts. These alternatives deliver the pristine, great-tasting drinking water you've come to appreciate. By opting for our DuPure-compatible replacement filters and handling routine maintenance yourself, you'll be able to save yourself money.

Start by clicking on the photo of your DuPure under-sink RO system above. You can add the needed filters to your cart. In some cases, you can save time by ordering all of the needed filters in one "filter kit". The RO membrane usually only needs to be replaced every two years, while the sediment and carbon filters are replaced every 6-12 months depending on water usage and water quality.

Filters and membranes compatible with DuPure's reverse osmosis systems are effective in eliminating a wide array of contaminants from water, such as lead, pesticides, sulfates, fluoride, nitrates, chlorine, pharmaceuticals, arsenic, and many others.
