Description
Take RO permeate to ultra-low dissolved solids with semiconductor-grade mixed-bed DI resin
H-F1035DI is a final-stage deionization cartridge filled with ResinTech MBD-15 mixed-bed resin. It is intended for applications that require very low ionic content after reverse osmosis, including aquariums, humidifiers, laboratory-style water preparation, and specialty ultra-pure water setups.
What this media is designed to do
MBD-15 ResinMixed-bed cation and anion exchange resin for final ionic polishing.
Very Low TDSSource lists 0–12 ppm output depending on feed water and resin condition.
Post-RO UseBest performance when fed with already-low-TDS RO permeate.
1/4″ / 3/8″Selectable elbow adapters support common RO tubing sizes.
Useful information without overstating health effects
This is a deionization product, not a mineral-enhancement cartridge. It removes dissolved ionic minerals rather than adding them. For drinking-water customers who prefer mineral taste, a remineralization cartridge may be installed after DI if compatible with the desired water profile.

Installation & maintenance
- ✓Confirm tubing, fitting size, and filtration position before ordering
- ✓Use cold water only and stay within listed pressure limits
- ✓Flush a new cartridge before drinking-water use when appropriate for the media
- ✓Replace based on measured performance, water quality, and usage
Match the filter to the water-quality goal
Use after an RO membrane in compatible countertop or under-sink systems. Feed-water TDS has a major effect on resin life; using DI directly on untreated tap water will exhaust it quickly.

Samuel L. –
This filter definitely improved the softness of our water. Soap lathers better, and no more chalky taste. I noticed a slight drop in flow rate after 6 months, but that’s expected. Just replaced it and back to normal. Solid product.
