In the last decade, the number of products designed to reduce contaminants in tap water has expanded significantly. In this article, I summarized a quick lesson on home water purification systems.
- Know the TASTE. Does your water taste funny or smell bad? Does it look reddish or leave
- Look for products that tackle specifically your problem. Filters reduce chemical contaminants, some metals, parasites, sediment. Provide about 1/2 to 1 gallon of water a minute.
- DEVICE. Choose a style that fits your needs: Pitchers with filters: Inexpensive. No installation; frequent filter changes (every 40 gallons).
Faucet with builtin filter — may require pro to install; filter changes every 100 gallons or so.
Device that mounts on existing faucet; filter changes every 100 gallons or so.
Countertop device that connects to faucet via hose; filter change starting at about every 100 gallons. Plumbed-in: Systems that install under sink and refrigerator filters that install directly to plumbing line. Both have long filter lives; generally require pro to install.
CERTIFY/VERIFY. Look for an NSF-certified product. And be sure to read the owner’s manual to make sure you change the filter appropriately.
