AQUA CREST3US-PF01 Under Sink Water Filter, NSF/ANSI 42 Certified Replacement for Filtrete® 3US-PF01, 3US-MAX-F01H, Delta RP78702, Manitowoc K-00337, K-00338, HF20 HF25 HF27, 2 Pack, No.AQU-WF00

Been getting these for years and we love them. It's a simple installation and turns our tap water into filtered water. No leakage and saves us a ton of money.

This water filter is so easy to install and change out every 6 months. It works great!!

This filter actually went on easier than the original filter. It's been on for over a month now and seems to be working perfectly. Water pressure and volume has not changed, taste has not change but the price was much lower. Having the two pack will make it easy for reorder and I won't have to drive all over town trying to find one in a store. The shipping was fast and I probably spent more days trying to find one locally than it took to have these sent. I never did find the correct one locally.I love the product, service and the convenience plus no one can beat the price savings.

As opposed to the 3M filter this replaces, this filter apparently uses seals that may deteriorate with the normal silicone O-ring grease used with Viton or some other seals. Not a problem, IF you read the instructions. Since the 3M came with a silicone lube already on the seals, one might not be prepared for the additional installation step. Also, I find it best to turn off the supply line when installing this filter. The O-rings are a tad smaller than the 3M, and I got a little spray out of the first one I installed. No problems with the supply line turned off. The filter works well and is a lot less expensive than the 3M.

We use them under our kitchen sink. Work great. I can tell when it’s time to change. Last around 6 months. Easy to replace.

A perfect fit and replacement for the original Filtrete filter. The prices for these are insane, though. I get about 5-6 months out of each filter on my kitchen sink faucet.

Quick delivery.

Good value
