Clean, great-tasting water directly from your tap — that's what a professionally installed water filtration system delivers. While Arlington Heights' Lake Michigan-sourced water meets all federal and state safety standards, many homeowners want additional filtration to remove chlorine taste and odor, lead, sediment, and other contaminants. We install under-sink, whole-house, and reverse osmosis filtration systems throughout Arlington Heights.

Water Filtration Systems We Install

Under-Sink Carbon Filters — Removes chlorine taste/odor, sediment, and some contaminants. Simple installation with a dedicated faucet or integrated into your main faucet. Filters need replacement every 6–12 months.

Water Filter Services FAQ — Arlington Heights

Is Arlington Heights tap water safe to drink?

Yes. Arlington Heights water meets all EPA and Illinois EPA standards. However, "safe" and "optimal" are different things. Many homeowners prefer to remove residual chlorine (taste/odor), reduce lead exposure from older home plumbing, or filter out additional contaminants for peace of mind.

What's the difference between a water filter and a water softener?

A water filter removes contaminants (chlorine, lead, sediment, etc.) to improve water quality and taste. A water softener removes hardness minerals (calcium, magnesium) to prevent scale buildup and improve appliance efficiency. Many Arlington Heights homes benefit from both.

How often do water filters need to be replaced?

It depends on the system: under-sink carbon filters every 6–12 months, RO membranes every 2–3 years (pre/post filters every 6–12 months), whole-house filters every 3–12 months depending on type and water usage. We can set up a replacement schedule for you.

Can you install a reverse osmosis system under my kitchen sink?

Yes. RO systems fit under most kitchen sinks. They require a cold water supply connection, a drain connection (for waste water), space for a storage tank (about the size of a small propane tank), and a hole in the sink or countertop for the dedicated faucet. Installation typically takes 2–3 hours.
