Kitchen water problems we fix
An under-sink filter in Chicagoland gives you clean drinking and cooking water straight from a dedicated faucet. We match the system to your water source and pipes and install it in one visit.
Pitcher filter is too slow
Pitchers hold a few cups and the cartridge clogs fast. Under the sink you get a full-flow filtered tap that is always ready.
Worried about lead
Lead usually comes from pipes and fittings, not the treatment plant. A system certified to NSF/ANSI 53 or 58 for lead reduction protects the water you drink.
Refrigerator filter not enough
We can connect the filter to your fridge's ice maker and water dispenser too.
PFAS and other contaminants
Many people now ask about PFAS. Look for systems certified to reduce PFOA/PFOS; reverse osmosis covers the widest range.
Buying bottled water
If the recycling bin is full of plastic bottles, a dedicated filtered faucet pays for itself and frees up the pantry.
Don't want to drill the counter
No drilling required in many cases: we use an existing hole or a system that feeds your current faucet.
Hard water and scale
Calcium and magnesium leave scale on kettles and faucets. Reverse osmosis removes most of it from drinking water; a softener treats the whole house.
What the install includes
- Water checkWe review your utility's water report and look at your pipes before recommending a system.
- System selectionCarbon, catalytic carbon or reverse osmosis — matched to taste, lead or PFAS concerns.
- Dedicated faucetWe use the sprayer or soap hole or drill a new faucet hole, including in stone.
- Drain connection for RORO systems need a drain connection — installed correctly to prevent backflow.
- Filter change planReminders and easy cartridge swaps so the filter keeps working.
- Whole-house optionsPoint-of-use filtration at the sink, plus whole-house treatment when your water needs it.
Options to choose from
Under-sink carbon filterA one- or two-stage carbon system for great-tasting water.
Remineralization stageAdds back minerals after RO for a better taste.
Tankless ROCompact RO systems without a storage tank — they fit tight sink cabinets.
Reverse osmosisThe most thorough filtration; includes a membrane, storage tank or tankless pump.
Under-Sink Water Filtration across Chicagoland
The same job looks different in a 1920s bungalow, a 1970s split-level and a new subdivision. Here is what we plan for in different parts of the region.
Prewar towns
Old galvanized pipes
Rusty or discolored water from old pipes needs a sediment pre-filter in front of the main cartridge.
Lake Michigan water
Is Lake Michigan water already safe?
Treated Lake Michigan water meets federal standards, but taste, chloramine and household plumbing can still be reasons to filter at the tap.
Berwyn, Buffalo Grove, Wood Dale, Lombard, Glen Ellyn, Wheaton
Well-water towns
Do I need a softener with a well?
Often yes — hard water and iron shorten filter life. A softener or pre-filter in front protects the drinking system.
Oak Brook, Batavia, Aurora, Lake Zurich, Crystal Lake, Hanover Park
Lead service line programs
How do I find out if I have a lead service line?
Your town's service line inventory shows the material; we can also look at the pipe where it enters the house.
Evanston, Skokie, Park Ridge, St. Charles, Crystal Lake, Arlington Heights

AfterHoffman Estates kitchen, 1990s two-story colonial: under-sink water filtration
A 1990s two-story colonial in Hoffman Estates, a typical kitchen for Hoffman Estates. What we started with: white cast-iron double sink. The reason for the call: tap water that didn't taste right. After: a matte black filtered-water faucet next to the main faucet and a compact reverse osmosis unit with a small white storage tank under the sink. On site this meant system selection, dedicated faucet, plus filter change plan.

A 1990s two-story colonial in Wood Dale, a typical kitchen for Wood Dale. The kitchen as it was: solid-surface integrated sink. The reason for the call: tap water that didn't taste right. After: a satin brass filtered-water faucet next to the main faucet and a tankless reverse osmosis unit with a small remineralization cartridge under the sink. On site this meant water check, drain connection for RO, plus filter change plan.

Under-Sink Water Filtration: common questions
Will a filter lower my water pressure?
The main kitchen faucet is unaffected — filtered water comes from its own tap.
Whole-house filter or under-sink?
It depends on the problem: taste and contaminants — under-sink; scale and sediment — whole-house.
How often do filters need changing?
Plan on new carbon cartridges once or twice a year and an RO membrane every few years — sooner with heavy use.
Can you drill a faucet hole in my quartz or granite?
Yes. Diamond core drilling is clean and safe for quartz and granite.
Is reverse osmosis water safe to drink every day?
Yes. RO removes minerals along with contaminants; a remineralization stage adds some back for taste if you prefer.
