Tap water filtration systems are a good choice if you’re just getting started with home water filtration. They’re low cost and easy to install, but let you experience the benefits of filtered water so you’ll know if you want to invest in a more involved system. When comparing the different systems out there, consider these factors first.

Effectiveness

A tap water filtration system’s ability to clean water is, naturally, its most important feature. Check the system’s performance data for stats on whether or not it can filter out chlorine, lead, mercury, pesticides, cysts, and industrial contaminants and, if so, what percent the these the filter can catch.

Company reputation

Only quality products develop a good reputation. Before you buy, check out the manufacturer’s reputation in magazines like Consumers Digest and on Web sites that compare various tap water filtration systems. A California Department of Health Certificate is another clear sign of a top quality filter.

Ease of installation

Nearly all tap water filtration systems are easy to install, but it’s a good idea to learn about the installation requirements before you buy. Keep in mind that while countertop and undersink tap water filtration systems may be slightly more complicated to install than faucet-mounted types, they often do a better job filtering and provide a better flow rate, too.

Cost

It’s pretty obvious a $20 tap water filtration system won’t do much, but there’s no reason to spend hundreds on any one, either. Some online price comparison will give you a good idea of how much to spend. When you’re comparing prices, factor in the cost of replacement filters, too.

Because there’s no single filtration system that’s right for every home, use these factors to compare several different brands and models of tap water filtration systems before you buy.
