A no-tools upgrade for your bathroom tap
Bathroom Sink Filter
A compact, point-of-use filter that attaches to your existing bathroom faucet — no tools, no drilling, nothing permanent. Water passes through a sediment layer and activated carbon before it reaches the tap, cutting the rust, cloudiness, and chlorine taste that older building pipes tend to add.
Bathroom Sink Filter at a glance
This cartridge runs on a different clock than everything else we install, and the reason is physics rather than a gimmick: activated carbon's chlorine capacity scales with how much carbon is actually packed into it, and a compact unit built to fasten onto a faucet spout holds a fraction of what a full sediment-and-carbon housing under your sink does. Less media, the same water volume passing through it, means it exhausts faster — which is why this is the one product on our menu you swap yourself every month instead of us doing it every six.
The category itself is well studied. Research on faucet-mounted point-of-use filters in households has found they reliably strip free chlorine — reductions of around 99% in tested systems — along with measurable drops in lead and other tap-sourced contaminants compared to unfiltered water from the same tap. That's the mechanism this product is built on: a real, measurable job done by a small amount of carbon and sediment media on a low-volume tap, not a token gesture.
This is one of the least invasive filters on our entire menu. Every drinking water system we install — including the electricity-free ultrafiltration tiers — requires drilling a small hole for a dedicated faucet; this one threads onto the tap you already have and comes off just as easily. The showerhead filter is just as non-invasive in its own right, and the kitchen faucet mount attaches to a faucet almost the same way — though that one sits on your counter, where this one doesn't. If you're renting and unsure what you're allowed to install, this is worth reading first — this product and the showerhead filter are both answers for anyone who'd rather not have that conversation with a landlord at all.
Worth repeating plainly: this is a taste-and-sediment filter for a low-volume tap, not a barrier against pathogens the way our drinking water systems are. That distinction matters less here than it would under your kitchen sink — you're not drinking multiple liters a day from your bathroom faucet the way you would from a filtered kitchen tap — but it's still worth knowing what you're buying. If you want water from this tap that's safe to drink outright, that's what a full drinking water system is for.

Benefits
- Removes visible sediment and reduces chlorine odor and taste
- 360° swivel spout, with a switch between a filtered aerated stream and a targeted rinse stream
- Fastens onto most standard faucets with no tools and nothing permanent — ideal for renters, and it comes off with you when you move
- Monthly cartridge swaps you do yourself in seconds — the new one just clips into place — we leave six at install, so you're stocked until our next visit
- An easy addition after a kitchen install, for lower-volume water like brushing your teeth
- This is a taste-and-sediment filter, not a full drinking water system — see our Drinking Water Systems if you want water you can drink straight from the tap it's installed on.
- Unlike everything else we install, the cartridge here is a monthly swap rather than a six-month one — it's a small filter doing a small job, and it loads up faster. You handle those yourself in seconds. Then every six months we replace the entire faucet unit, so you're always running a new device rather than an aging one.
What's included
- Full installation by an English-speaking technician
- Six replacement cartridges left with you at install — each one clips into place in seconds, one per month for six months
- Optional maintenance plan — we'll track your filter schedule and reach out when it's due
Maintenance
Two things happen on this one. The cartridge is a monthly swap you do yourself — seconds, no tools — and we leave six at install to cover your first six months. Then at the six-month mark, when we're back for your other systems, we replace the entire faucet unit and restock you with another six cartridges. That's what the $600 covers: a complete new unit plus six months of cartridges, the same as what you got on install day, which is why the price matches. On the maintenance plan it's displayed as $100/mo, billed every 6 months.
