Installation and Maintenance Tips
Professional installation is recommended for under-sink RO systems, but ONEMI’s 45-degree twist filter change design means end users can replace cartridges themselves in about 3 seconds — no tools or plumber needed.
Regular maintenance is crucial for longevity. Replace pre-filters every 6-12 months, RO membranes every 24-36 months, and post-carbon filters annually. Most ONEMI systems feature LCD displays that show remaining filter life and TDS readings in real time.
How to Choose the Right RO vs UV vs UF
Selecting the right RO vs UV vs UF depends on your water source, household size, and budget. Start by testing your water quality — check for hardness, chlorine levels, and any specific contaminants of concern.
The FSA composite filtration architecture is ONEMI’s core technology, combining sediment filtration, activated carbon adsorption, and scale inhibition in a single cartridge. This 3-in-1 design delivers comparable filtration performance to traditional 5-stage systems at lower maintenance complexity.
