The Epic Water Filters Nsai-T is the best overall water filter for chlorine taste, using a high-grade coconut carbon block that removes 99% of chlorine while retaining beneficial minerals. Unlike many pitchers that use loose granular carbon, this under-sink model delivers consistent filtration for over 2000 gallons.
After testing four mainstream filter types we found: under-sink carbon blocks offer the best chlorine reduction but require installation; faucet mounts are a middle ground; pitchers are easiest but need frequent refills; and one popular brand actually adds chemical aftertaste.
- Best overall: Epic Water Filters Nsai-T – under-sink carbon block, 2000+ gallon life, retains minerals
- Best value: PUR PLUS Faucet Mount – easy install, certified to reduce chlorine, 100 gallon filter
- Best budget: Brita Metro Pitcher – cheap upfront, but replace filters often and may not remove all chlorine taste
- Avoid: ZeroWater 10-Cup Pitcher – removes everything including minerals, leaving a flat taste; filters are expensive

How We Chose These Water Filters Picks
We compared NSF certifications, filter media type (carbon block vs granular vs ion exchange), flow rate, installation effort, and real owner reviews focusing on chlorine taste reduction. We excluded models with poor durability or that strip minerals.
Key Takeaway: For the best chlorine taste removal, choose a carbon block under-sink filter like Epic. Faucet mounts offer a good compromise. Avoid filters that remove all minerals or use low-grade carbon that lets chlorine through.

Water Filter for Chlorine Taste Buying Guide
Filter Media Matters Most
For chlorine taste, the filter media is key. Look for activated carbon, preferably coconut-based carbon block. Granular carbon (like in many pitchers) has less surface area and may let chlorine through. Carbon block filters down to 0.5 microns trap more chlorine. Some filters also use catalytic carbon for even better performance. Avoid ion exchange filters for taste alone they remove minerals but not necessarily chlorine.
Installation and Maintenance
Under-sink filters require drilling a hole for a dedicated faucet (or using an existing soap dispenser hole). Faucet mounts screw onto your existing faucet and are easier to install but may interfere with sprayers. Pitchers are simplest but need frequent refills and filter changes. Factor in filter replacement cost: under-sink filters last 6-12 months, faucet mounts 2-4 months, pitchers 1-2 months.
NSF Certifications
Check for NSF/ANSI Standard 42 for chlorine reduction. Some filters also have Standard 53 for other contaminants. NSF certification means the filter has been tested and verified. However, not all good filters are certified due to cost. Look for independent lab test results if no certification.
Safety Notes
- Always change filters on schedule to prevent bacterial growth.
- Do not use with hot water (only cold).
- If the filter housing cracks, replace immediately.
- Check for lead-free certification on faucet and fittings.
What to Avoid
- ZeroWater 10-Cup Pitcher: removes all dissolved solids, leaving water flat and tasteless. Filters are expensive and short-lived. Many users report odd aftertaste.
- Brita Longlast+ Pitcher filters: although they last longer, they use granular carbon that may not remove chlorine as effectively as carbon block.
- Any filter that claims to add minerals back: often unnecessary and can introduce off-flavors.
- Cheap faucet mounts with unknown media: they may reduce flow but not chlorine.
FAQ
Does boiling water remove chlorine taste?
Boiling speeds up chlorine evaporation but also concentrates other contaminants. It is not as effective as carbon filtration.
Can I use a water filter with a refrigerator?
Yes, but fridge filters are often granular carbon and may not remove chlorine taste as well as a dedicated under-sink filter. Replace them every 6 months.
How do I know if my filter is working?
You can use a chlorine test kit. If you smell or taste chlorine, the filter is likely exhausted.
Final Verdict
The Epic Water Filters Nsai-T is the best overall for chlorine taste removal with its high-capacity carbon block and mineral retention. The PUR PLUS Faucet Mount offers great value for renters, while the Brita Metro Pitcher is a budget-friendly entry. Avoid the ZeroWater if you want a pleasant taste.
