Reverse Osmosis
vs. Pitcher Filter
Pitcher filters are convenient and cheap upfront. But for Columbus water — with PFAS, chloramines, and nitrates — they leave a lot in your glass. Here's what the data actually shows.
- RO removes PFAS — pitcher filters do not
- RO handles Columbus chloramines — pitcher filters struggle
- RO costs ~$0.04/gallon long-term vs. ~$0.25 for pitchers
- Pitcher filters require refilling every 10–15 minutes
Columbus Water Has Specific Contaminants Pitcher Filters Can't Handle
Columbus uses chloramine disinfection (harder to remove than chlorine), has detectable PFAS levels subject to new EPA limits, and serves areas with agricultural nitrate runoff. Standard pitcher filters were not designed for these contaminants. The table below shows what each option actually removes.

The Real Cost Over Time
Pitcher filters look cheap at the register. The math changes when you factor in cartridge replacement and what you're actually getting.
RO cost based on Pure Aqua Columbus Alkaline RO system. Pitcher cost based on Brita Longlast filter usage for family of 4. Estimates vary by household usage.
RO costs ~$0.04 per gallon. Pitcher filters cost ~$0.25 per gallon.
Over five years, a family of four using a pitcher filter spends more per gallon than RO — and gets far less protection. The upfront investment in RO pays for itself in both cost and peace of mind.
When a Pitcher Filter Is Acceptable
- You rent and can't install under-sink equipment
- You only need to reduce chlorine taste temporarily
- You're in a short-term living situation
- Your water has already been tested and shows no PFAS, nitrates, or heavy metals
- You're using it as a backup while waiting for RO installation
When You Need Reverse Osmosis
- You're on Columbus city water (chloramine + PFAS concern)
- You have young children, pregnant family members, or immunocompromised individuals
- Your water test shows PFAS, nitrates, arsenic, or elevated TDS
- You want to stop buying bottled water permanently
- You want the cleanest possible water for cooking and drinking
- You're on well water with unknown contaminant profile
Common Questions
Does a Brita filter remove PFAS from Columbus water?
Standard Brita pitcher filters do not remove PFAS. Brita's "Elite" filter claims some PFAS reduction, but independent testing shows inconsistent results. Reverse osmosis systems remove 95–99% of PFAS and are the EPA-recommended method for PFAS reduction in drinking water.
Is reverse osmosis worth it compared to a pitcher filter?
For Columbus homeowners, yes. A quality RO system costs $800–$1,500 installed and removes 95–99% of contaminants including PFAS, nitrates, lead, arsenic, and chloramines. Pitcher filters cost less upfront but require frequent cartridge replacement and miss many contaminants found in Central Ohio water.
Does reverse osmosis remove chloramine from Columbus water?
Yes. Columbus switched from chlorine to chloramine disinfection. Standard carbon pitcher filters struggle with chloramine removal. Reverse osmosis systems with catalytic carbon pre-filters effectively remove chloramines — which is why RO is the preferred solution for Columbus drinking water.
How long do reverse osmosis filters last?
RO pre-filters and post-filters typically last 6–12 months. The RO membrane itself lasts 2–5 years depending on water quality and usage. Annual maintenance cost runs $100–$200 — comparable to or less than ongoing pitcher filter cartridge costs for a family.
What does a pitcher filter actually remove?
Standard pitcher filters (Brita, PUR) primarily reduce chlorine taste and odor, some heavy metals like lead and copper at the tap, and particulates. They do not reliably remove PFAS, nitrates, arsenic, fluoride, chloramines, or dissolved solids — all of which have been detected in Central Ohio water supplies.
