Which water faucet filter is right for you?

Our Recommendations


The Instapure F2 Faucet Filter is one of the more affordable water faucet filters on the market. If you're only looking to remove the taste and odor of chlorine, then the Instapure F2 is a good choice.


The PUR FM9400B Faucet Filter removes more than just the taste and odor of chlorine: it also reduces Mercury and 99.9% of microbial cysts.


The Culligan Faucet Filter will reduce far more contaminants than most faucet filters, and it has a respectable filter life of 200 gallons. It is a great bargain at $19.99. The only downside to this faucet filter is looks, but that is subjective.
