I have been using the PUR water filter since Milwaukee Wi. Crypto water problem. The water taste clean,  it fits right on your faucet{different adapters are included to fit your faucet).You save so much $$ buy not buying all those bottles(and environment).You will get a slite difference in water pressure but you can remove the filter easily and pop it back on, but its really not necessary.Your water will always have a good taste or lack of chemical taste. I LOVE THIS FILTER
