Under the sink water purifier

[fitme40]

I am really wanting to get an under the counter water purifier for my kitchen sink. I need to stop buying bottled water and get one of those refillable bottles to use with water from the tap. Can anyone suggest a brand of purifier to buy? How hard to install? How much money? Also, what's the best type of refillable water bottle to buy?

Thanks,
Laura

I used to have a brita I attached on the spigot. Very inexpensive & easy to install. I moved & it didn't fit on my new spigot, so I bought the pitcher.

We have the reverse osmosis system from Watts. We got the whole package from Costco for about $150 about 8 years ago and it's still working great. The filters are very easy to replace.
