Renters and apartment dwellers can’t install whole house filters or drill under the sink without landlord permission. But that doesn’t mean settling for unfiltered tap water. The filters below require zero installation, zero drilling, and zero landlord approval — while still delivering NSF-certified contaminant removal.
- Best overall for apartments: Clearly Filtered Pitcher — NSF 42, 53, 244 · PFAS, lead, fluoride · 365+ contaminants · no installation
- Best for high volume: Berkey Big Berkey — 2.25 gallon gravity filter · no electricity · bacteria & viruses
- Best under-sink (with landlord permission): APEC ROES-50 — NSF 58 RO · broadest removal · ~$60/year
- Not recommended: Brita Standard — NSF 42 only, no PFAS or lead removal
The Clearly Filtered Pitcher is the best apartment water filter because it delivers NSF-certified PFAS, lead, and fluoride removal with zero installation. Fill it, let it filter, done. Three simultaneous NSF certifications (42, 53, 244) make it the most independently verified pitcher available — the only one certified for microbiological reduction (NSF 244) alongside health contaminants. At 365+ contaminants tested, no other pitcher comes close. Perfect for renters who move frequently — compact, portable, and setup takes 30 seconds.
- Zero installation — no drilling
- NSF 42 + 53 + 244 certified
- Removes PFAS, lead, fluoride
- Portable — moves with you
- 365+ contaminants tested
- Slower flow than Brita
- Filter every 100 gallons (~3-4 months)
- Lower volume than Berkey
The Berkey Big Berkey is the best option for apartment dwellers who need higher volume — 2.25 gallons ready at all times — or who want bacteria and virus protection that pitchers don’t offer. No electricity, no installation, no water pressure required. Gravity does the work. Black Berkey elements are independently lab-tested for bacteria, viruses, heavy metals, chlorine, and many other contaminants. The 3,000-gallon filter life means ~$50/year running cost — the lowest on this list. Trade-off: no NSF certification, so claims are not independently audited to NSF standards.
- Zero installation — gravity fed
- Removes bacteria & viruses
- 2.25 gal capacity — high volume
- 3,000 gal filter life — ~$50/year
- No electricity needed
- No NSF certification
- Large countertop footprint
- Slow gravity filtration
- High upfront cost (~$300+)
If your landlord allows modifications, the APEC ROES-50 is the best under-sink option — NSF 58 certified, removes 99%+ of PFAS, lead, fluoride, and 1,000+ contaminants at ~$60/year. Installation requires drilling one hole in the sink for the dedicated faucet. Many landlords approve this since the hole is small and the filter can be removed when you move. Always get written permission before drilling. If permission is denied, Clearly Filtered Pitcher is the best no-installation alternative.
- NSF 58 — broadest certified removal
- Removes PFAS, lead, fluoride, arsenic
- Lowest annual cost (~$60/year)
- Removable when you move out
- Requires drilling — landlord permission
- Under-sink space needed
- Wastes 3-4 gal per gal filtered

How to choose an apartment water filter
Some leases prohibit any modifications including under-sink filter installation. Others allow minor modifications with written permission. Always check before drilling or connecting to water supply lines. Pitcher and gravity filters like Clearly Filtered and Berkey require no modifications — safe for any rental situation.
The Clearly Filtered Pitcher holds about 10 cups of filtered water at a time — sufficient for drinking and cooking for 1-2 people. For families of 3-4, the Berkey’s 2.25-gallon gravity tank is more practical. If you move frequently and travel, the Clearly Filtered pitcher is more compact and easier to transport.
Apartments in buildings constructed before 1986 may have lead pipes or lead solder in the plumbing — even if the municipal supply is clean. If your building is older, NSF 53-certified lead removal (Clearly Filtered) is a priority. Ask your building manager for the last water quality test results.
Clearly Filtered: ~$90 upfront + ~$90/year. Berkey: ~$350 upfront + ~$50/year. APEC ROES-50: ~$200 upfront + ~$60/year. For short-term rentals (under 1 year), Clearly Filtered has the lowest total cost. For long-term apartment living, Berkey’s low running cost ($50/year) makes it cheaper over 3+ years.
