We offer two replacement filter kits so you can get exactly what you need — and avoid paying for filters you don’t.
-
Year 1 Kit shown on this page (Includes RO Membrane):
Ideal for your first full replacement, this kit includes all filters plus the RO membrane, which typically lasts up to 24 months. -
Year 2 Kit (Without RO Membrane):
After the first year, you only need to replace the pre- and post-filters, since the RO membrane is still good for another year. This kit helps you save money while keeping your system performing like new.
By offering two kits, we make it easy to follow the recommended replacement schedule and reduce waste — so you only buy what your system truly needs.
*Filters may need to be replaced more often than indicated, depending on water contaminant levels and volume of water being treated.
Replacements & Add Ons
Q:
How much do Ulitma water filters cost?
A:
Ultima Reverse Osmosis propriety water filters can be expensive. But we offer high-quality compatible filters, RO membranes, and cartridges, that work well with Ultima RO systems and can save you money. Basically, the filters cost much less, but provide that same clean, great-tasting drinking water you'd expect. By installing Ultima-compatible reverse osmosis filter replacements and taking care of routine system maintenance yourself, you can save quite a bit of money.
Q:
How do I order replacement filters for my Ultima Reverse Osmosis water filtration system?
A:
Begin by selecting the image of your Ultima RO system displayed on this page https://espwaterproducts.com/collections/ultima-reverse-osmosis. This will allow you to add the appropriate filters to your shopping cart. For convenience, consider opting for a "filter kit" which includes all the necessary filters, though it might not be available for every Ultima model. Remember, the RO membrane typically requires replacement every two years, while sediment and carbon filters need changing every 6-12 months based on your water consumption and its quality.
Q:
What contaminants will these Ultima-compatible filters remove?
A:
Ultima-compatible reverse osmosis filters and membrane can remove common pollutants from water including pesticides, sulfates, fluoride, nitrates, lead, pharmaceuticals, arsenic and more. The RO system's carbon filter will also remove chloramines and chlorine.

Q:
How often should I replace filters in my Ultima Reverse Osmosis system?
A:
In Ultima RO systems, replace sediment and carbon pre-filters every 6–12 months, and the RO membrane every 2 years for reliable performance and water quality. Replacing on schedule helps maintain the benefits of RO drinking water — learn more on the RO advantages page. Explore replacement options in the Ultima RO Replacement Filters collection.
Q:
What filter kits are compatible with Ultima RO systems?
A:
ESP Water carries multiple Ultima RO filter kits including the Ultima Green RO 4-Stage, Ultima Green RO 5-Stage, Ultima RO 5 QC System, Ultima VI RO System, and Ultima VII RO System. Match your model to the correct kit for optimal performance.
Q:
How do I know which Ultima RO replacement filters I need?
A:
Start by identifying your system model (4-stage, 5-stage, or advanced Ultima VI/VII). Then use the ESP Water Replacement Filter Finder tool or browse the Ultima RO filters & parts collection to find the exact match.
Q:
What are the signs Ultima RO filters need replacing?
A:
Common signs include slow water flow, poor taste or odor, cloudy water, or higher TDS readings. Slow flow can be due to clogged filters — see causes in the Why RO Water Flow Is Slow page. Replace any outdated filters as soon as you notice these symptoms using parts from the Ultima RO Replacement Filters collection.
Q:
Can I install Ultima RO filter replacements myself?
A:
Yes — Ultima RO filters are designed for straightforward DIY replacement. Turn off feed water, depressurize the system, and swap cartridges following your system manual. For general instructions, see the RO Filter Replacement Guide and then choose the correct kit from the Ultima RO filters collection.
Q:
How do Ultima RO replacement filters improve water quality?
A:
Fresh sediment filters trap dirt and particles, carbon blocks reduce chlorine and tastes/odors, and the RO membrane removes dissolved solids and contaminants — preserving the key benefits of reverse osmosis water described on the RO advantages page. Replacing filters on schedule ensures consistent water purity.
Q:
Are all Ultima RO replacement filters the same size?
A:
Not always. Ultima systems use different stage configurations and filter sizes depending on the model (e.g., 4-stage vs. 5-stage vs. Ultima VI/VII). Always verify your system model and select the correct replacement kit from the Ultima RO Replacement Filters collection or via the Replacement Filter Finder tool.
