Dispensing Options

 

On-counter

There are two differen on-counter options.  dispenser sit on the counter, with a line connecting directly to the faucet (can include a diverter valve), while others have a dispensing option as part of the unit. Models use a range of technologies, including activated carbon and reverse osmosis. Effectiveness varies widely between models, but many on-counter filters will reduce a wide array of contaminants.

Pros: Allows for easy access to both filtered and unfiltered water. Typically requires relatively infrequent filter changes. Ideal for filtering both drinking and cooking water.

Cons: Requires installation and possibly plumbing modification. 

 

Floor-model

Floor models are an all-in-one approach.  In most cases, the dispenser includes a carbon filter, but most units can also be hooked-up to other filtration options for more challenging water issues.  Can include hot and cold options.

Pros:  Familiar form factor - the "water cooler" is an office icon.  In most cases, easy to install.

Cons: Takes up floor space.  No option for sparkling.

 

Under-sink

Under-Sink filters are mounted underneath the kitchen sink, where they are fitted to the water supply line. Some models have a separate spout or faucet for water collection. Models use a range of technologies, including activated carbon to reverse osmosis (or both). Effectiveness varies widely between models, but many under-sink filters will reduce a wide array of contaminants.

Pros: Placed out-of-sight under the sink. Typically requires filter changes relatively infrequently. Ideal for filtering both drinking and cooking water.

Cons: Requires installation and possible plumbing modification.

 

Faucet-mounted

Faucet-mounted filters attach directly to the end of the faucet. Most can be pivoted to an "on" or "off" position, allowing you to collect filtered water for drinking and cooking. This filter style typically uses an activated carbon filter that can remove contaminants and improve taste and odor. Models vary, but many reduce chlorine, lead, mercury and (less frequently) disinfection byproducts.

Pros: Relatively inexpensive. Easy to install. Allows user to switch between filtered and unfiltered water. 

Cons: Does not work with all faucet styles. May slow down faucet flow rate. Typically must change filter more frequently than with countertop or under-sink filters.

 

Pitcher

Pitchers are typically fitted with an activated carbon filter that can remove contaminants and improve taste and odor. Models vary, but many reduce chlorine, lead, mercury and (less frequently) disinfection byproducts. 

Pros: Inexpensive. No installation required. Available in various sizes and styles.

Cons: If filters are replaced regularly, yearly cost may equal expense of faucet, countertop or under-sink filters. Can require frequent filter changes. Filtering is slow.
