The ins and outs of water filters


October 2019

There are several factors to consider when choosing a water filter. Some contaminants may be difficult to remove, or there may be just one technology that effectively removes or reduces the level of a specific chemical. Another consideration is cost — filters vary in price depending on the technology they use. The layout and size of your kitchen may also be a factor to consider when it comes to picking a countertop, faucet-mounted or under-sink filter.
