A home water filter provides a safer source than untreated tap water for drinking and cooking.
You can use a counter-top pitcher with a replaceable carbon filter. This is a popular water filter for renters because there's nothing to install, it's completely portable.
Brita is the most popular brand of counter-top pitcher filter. It makes a good tasting water, though it doesn't filter out as many contaminants as other types of filters and the water reservoir is made of plastic.
It's inexpensive though, and you can buy one at most local drug stores, and even larger grocery chains carry them now, usually in the bottled water isle.
For a filter you can easily attach to the faucet, Brita does make one, and there's another brand called Pur which filters out more contaminants than Brita, Pur is the brand I have on my kitchen faucet for when our local spring water is not available (occasionally the water tables get low enough that our local spring water sources stop flowing). The faucet models are handy. There's nothing to take up counter space, and you can turn them on and off so when you're washing dishes you can use tap water, and switch to the filtered water for drinking and cooking water.
Reverse osmosis filters are usually installed under the sink, with a separate faucet for the filtered water, and require a bit of cosmetic "surgery" on your sink or countertop.
You may also want to consider a shower filter for your home. Think about it - our skin is the largest organ of our body, and it's quite permeable. When we take a hot shower we just open up all those pores!
A number of shower filters serve a dual purpose, reducing the amount of water used per shower, as well as filtering contaminants from the water. Some even have varying spray options so you can choose more of a massaging pulse, a steady stream, or a combination.
When you're ready to make a larger investment in water filtration there's the option of installing a system to filter the water for your whole house. This usually is installed in the basement, or sometimes in the garage.
There's a number of types of water filters, including:
- reverse osmosis
- UV light
I'm no expert to recommend the best home water filter for a whole house system. I refer to the National Geographic Green Guide article on home water filters . You'll see this article linked on other pages in this website as well. It's got a lot of important information about water contaminants, and the different models of filters available. I also read consumer reviews on Amazon, a lot of savvy folks share their honest opinions, knowledge and experiences with the products.
