You can grab a basic under-sink filter for about $50. It’s the “I’ll try anything once” model, usually with a single carbon cartridge. It will definitely remove the pool smell, but don’t expect it to remove heavy metals.
Mid-range units, the kind that actually target lead or chlorine byproducts, land between $150 and $350. These often have multiple stages (sediment + carbon + a fancy name like “KDF”).
On the high end, you’re looking at $500 to $1,000+. We’re talking reverse osmosis systems with tanks, dedicated faucets, and enough filters to make a chemistry professor jealous. Yes, your wallet will weep, but your tongue will rejoice.
Installation: The "Sweat Equity" Tax
If you’re handy and the universe hasn’t designed your sink pipes to be a sadistic puzzle, DIY installation costs you $0 in labor. Just your time and maybe a few curse words when you drop a washer.
Most under-sink filters are designed to be “plug-and-play.” You might need a drill for the faucet hole (if you’re adding a dedicated tap), but the actual tubing is color-coded. It’s adult LEGOs, with water pressure involved.
But if you call a plumber? Expect to pay $150 to $400 just for them to show up, wiggle some pipes, and test it. That’s before the rare emergency call, which can jump to $800 if they find a rusted valve. Pro tip: Plumbers are wizards, but wizards charge by the hour.
