Define the job
A sediment filter, catalytic carbon tank and specialty contaminant cartridge are not interchangeable. Write down the exact outcome you need and ask for performance data at the expected flow rate.

Whole-House Water Filter Guide
A whole-house filter treats water before it reaches most fixtures, but no single filter removes everything. Choose the media and certification around a tested concern, then size the system for peak flow so showers and appliances do not lose pressure.
Plan for the real flow rate
Small housings can become bottlenecks when several fixtures run. Count bathrooms, high-flow fixtures and simultaneous use, then compare the manufacturer’s service-flow rating.
Ownership cost
Include replacement media, cartridges, service access and disposal—not only the purchase price. A bypass loop and pressure gauges make maintenance easier.
At a glance
| Feature | Question to ask |
|---|---|
| Media | Which substances is it designed to reduce? |
| Certification | Is the complete system certified for that claim? |
| Service flow | What pressure drop occurs at peak household demand? |
| Capacity | How is replacement timing determined? |
Questions homeowners ask
Frequently asked questions
Will it remove chloramine?
Some catalytic-carbon systems are designed for chloramine reduction, but verify the complete system’s performance data and required contact time.
Is a prefilter necessary?
It depends on sediment load and the main media. A prefilter can protect downstream equipment but also adds maintenance and pressure drop.
Do I still need an under-sink filter?
Possibly, if the drinking-water goal requires a different technology such as reverse osmosis.
