If you must remove inorganic chemicals such as salts, metals (including lead), minerals, nitrates, asbestos, and some organic chemicals, consider a reverse-osmosis (RO) water filter. Actually, most models include carbon pre-filters and post-filters, which will catch sediment, pesticides, herbicides, THMs, and radon. RO filters remove lead, but some don’t remove chlorine (if this is claimed, request proof of performance). The carbon post-filter is used to improve the water’s taste. Pre- and post-filter cartridges should be replaced annually. Most RO filters are connected directly to plumbing and are located beneath the sink. A small tank stores clean water until needed, and tainted water drains out through a line connected to the sink trap. Drinking water flows through a special, separate sink-top spout. Some models have an automatic valve that eliminates the waste typically associated with RO filters—conventional models waste about 3 gallons for every gallon of water they produce. They generally cost from $200 to $400.\n\n

is your tap water safe to drink unfortunately

Is your tap water safe to drink? Unfortunately, as discussed in the article Is Your Water

Safe?, it may not be. Because unhealthy levels of contaminants such as bacteria, lead,

and pesticides are found in both metropolitan and well water supplies, it’s important

to know whether pollutants exist in your water. And, if they do, you need to know

how to supply your home with clean water.

Buying bottled water is the quickest and, initially, cheapest way to get clean drinking

water. But over the long haul, it is far more expensive, and plastic bottles are wasteful

and an environmental blight. Producers of bottled waters are regulated by the same

standards imposed on public water systems and are also self-regulated by the

International Bottled Water Association. Club sodas, carbonated waters, seltzers, and

waters containing more than 1 percent flavoring are not covered by these

standards. Water Filteration is the more permanent solution. Many types of water

filters are made, and they range widely in sophistication and price. They may use

reverse-osmosis, activated carbon, or ultra-violet rays to clean or purify water. Should

you buy an under-the-sink reverse-osmosis filter, or will a simple spout-mounted

carbon filter do? Scores of companies claim to have the latest and greatest answer to

your water needs. What are your other options? The effectiveness of a water filter at

removing specific contaminants depends upon the technology used. So, it’s important

to know what needs to be removed from your water—and that involves testing. This

section of HomeTips explores the issues of clean drinking water, how to get water

testing accomplished, comparing filter technologies, and how to install a water filter.

Types of Water Filters

If the only problem with your water is grit, dirt, sediment, rust, or other such particles,

a screening filter may be sufficient. Made of fiber, fabric, ceramic, or another

screening medium, these simply catch particles—including, in some cases, small

organisms like cysts and some bacteria. But don’t rely on them to handle disease-

causing organisms, VOCs, metals, or the like. If your water tastes, smells, or looks

bad, a filter containing activated carbon (AC) may solve the problem. If you want

to remove chlorine, pesticides, herbicides, radon, trihalomethanes (THMs), and some

inorganic chemicals, carbon may do the trick.Carbon Water Filters Some, but not all,

carbon filters are effective at reducing lead content. Solid-block and pre-coat

absorption filters trap lead. Check the certification of the unit you’re interested in

buying and, if claims are made regarding lead removal, ask for proof. You can’t rely

on a conventional carbon filter to remove salts, nitrates, nitrites, and some metals. And

you shouldn t rely exclusively on one to remove

you shouldn’t rely exclusively on one to remove organisms. In fact, be aware that a

carbon filter will accumulate the contaminants removed from water, and bacteria may

even breed in it, so you must replace filter cartridges religiously, according to the

manufacturer’s recommendations. A carbon filter that contains pesticide silver may

be registered—but, remember, is not endorsed—by the EPA. Studies show that these

are not fully effective at eliminating bacterial growth or microbiological contaminants.

Again, be sure any such claims are substantiated. Effectiveness of a particular carbon

unit is a factor of the amount of activated carbon it contains. You can buy whole-

house, under-counter, countertop, and faucet-mounted styles, but the $30 faucet-end

models are only marginally effective. Known as point-of-entry (POE) systems, whole-

house units are recommended where a contaminant such as radon poses a threat to the

entire household.

Reverse Osmosis Water Filters

If you must remove inorganic chemicals such as salts, metals (including lead),

minerals, nitrates, asbestos, and some organic chemicals, consider a reverse-osmosis

(RO) water filter. Actually, most models include carbon pre-filters and post-filters,

which will catch sediment, pesticides, herbicides, THMs, and radon. RO filters

remove lead, but some don’t remove chlorine (if this is claimed, request proof of

performance). The carbon post-filter is used to improve the water’s taste. Pre- and

post-filter cartridges should be replaced annually. Most RO filters are connected

directly to plumbing and are located beneath the sink. A small tank stores clean water

until needed, and tainted water drains out through a line connected to the sink trap.

Drinking water flows through a special, separate sink-top spout. Some models have an

automatic valve that eliminates the waste typically associated with RO filters—

conventional models waste about 3 gallons for every gallon of water they produce.

They generally cost from $200 to $400.

Countertop water distiller purifiers water by turning it to steam.

Water Distillers

If you just want a portable, sink-top appliance that will rid water of most dissolved

solids, such as salts, asbestos fibers, metals, minerals, particles, and some organic

chemicals, an inexpensive water distiller may be just the thing. Distillers heat water

until it turns to steam and then condenses the steam back into water in a separate

chamber, leaving behind anything that won’t travel in the steam. Unless coupled with

a carbon filter, they will not remove all chemical pollutants and all bacteria. Most

have to be filled manually, they use a considerable amount of electricity to operate,

and they may take several hours to produce

and they may take several hours to produce 1 gallon of water. Prices range from about

$80 to $400—most popular models are about $200.

UV Water Purifiers

UV whole house water filteration, which typically cost $150 or more, may kill

bacteria and viruses, and clear the taste and odor of water, but they are not effective

against chemical pollutants and may not work against cysts and spores. UV may be

combined with carbon filters to kill bacteria; these units tend to cost from $300 to

$700.

Buying a Water Filtering Faucet

With the popularity of water-treatment devices, a number of manufacturers have

introduced products that integrate water systems seamlessly into the kitchen. For

example, American Standard makes the Streaming

an under-sink

filter to deliver filtered water through the main kitchen faucet.

Frigidaire offers a built-in PureSource Ice & Water Filter in its Gallery Side-by-

Side refrigerators, and the GE Profile Performance Side-by-Side refrigerator offers a

“Water by Culligan” built-in filter. Just be sure whatever product you buy utilizes the

type of filter needed to mitigate your water problems. Before you buy, shop around,

scrutinizing price features capacity frequency

scrutinizing price, features, capacity, frequency, and cost of filter replacement and

warranties. For a listing of certified units and the contaminants they remove, you can

contact the independent testing organization NSF International at (800) NSF-HELP

and request the Water Fact Kit. You can also its Certified Product Database at

www.nsf.org. By doing your homework, you’re sure to find a product that will offer

your family clear, clean water for many years.
