The best way to really know what's in your water is to test it at your home. Your water company's numbers are averages, and pipes between the plant and your kitchen can change what comes out of your faucet. Here's what we recommend:
Outside the US? Our mail-in test kits only ship in the United States for now, and we're sorry we can't send one to you yet. To test your own tap, contact an accredited drinking water lab near you, or ask your water supplier: many will test a home's tap water on request.
In Canada? We're still confirming whether SimpleLab can ship test kits to Canada. Until then, your local public health unit or an accredited lab near you can test your water (some provinces test private wells for free).
Tests are mailed to your door with a prepaid return label and processed by SimpleLab's certified lab network.
Got your results back? Upload them in your member account and we'll email you updated recommendations based on what's actually in your water.
A long-term fix for your actual water, not a prettier bandage. Pick as many as you like.
Starting ideas, based on your water report. Play with the buttons below to see your options. These are based on the water report we email you. For more accurate results, get your home water test: when your results come in, we'll email you updated recommendations based on what's actually in your water. Your answers, budget, and picks save to your free member account.
Our standard: honesty. Every product shows exactly what backs it up. Certified products come first, and anything that isn't certified is labeled so. Brands can't pay to be listed or ranked.
Whole-home systems mostly handle sediment, chlorine, and hard water. Drinking-water systems target the contaminants in your report. Your water decides whether you need one or both.
Many people take care of their drinking water first, then add whole-house filtration for bathing and everything else. Choose any order.
Once you've added products to My picks, we'll create a one-page summary of your water and those products. Email it to yourself or save it as a PDF, send it to your landlord before you buy, and your picks stay saved while you wait to hear back.
