AQUA CREST Faucet Filter Replacement for All PUR®Plus Water Filter Replacement, PUR® Filter Replacement RF-9999®, NSF 42 Certified, 600-Gallon Long Lifespan, 2 Pack, Packaging May Vary

Great value — clean water, easy setup, two filters for the price I picked up this 2-pack of alkaline faucet filters and I'm genuinely impressed for the price point. Setup took about 2 minutes — the universal adapter fit my kitchen faucet with no issues, and switching between filtered and unfiltered water is simple with the toggle. The water tastes noticeably cleaner right away. I live in an area with harder tap water and the difference was immediate — no more chlorine taste, and the water actually tastes smooth. The flow rate is solid too; I've used other faucet filters that slow to a trickle, but this one keeps a decent stream even in filtered mode. Getting two filters in the pack is a nice touch. Each one is rated for a good amount of use, so you're set for a while before needing replacements. The build quality feels sturdy enough — it's not flimsy plastic that feels like it'll crack in a month. If you're looking for an affordable way to upgrade your tap water without committing to an under-sink system or a pitcher you constantly have to refill, this is a solid pick. Would buy again.

These filters work great and much better value than original Pur. Last a good while and filters my water very well.

I bought these to use in my kitchen sink filter. They fit as well as the name brand filters and work just fine! Very easy to install.

These filters are great. Very inexpensive, they install with ease and seem to do a good job filtering - the water taste good and doesn't show any obvious signs of chemicals or any other contaminants when it's filtered. Aqua Crest or whoever manufactures them says they last for 600 gallons, though, which is hilariously far from true. More like 100 gallons.

If you have a PUR in-faucet water filtration unit, by all means get these. The PUR system is a really good system for providing me with pure, clean water in my kitchen sink. Most big-box stores stopped carrying the PUR products a couple of years back. The closest one that carries the PUR product line is 15 minutes away (sorry, I ain't doin' that no more). That's OK, because I can buy this 4-pack for less than three of the PUR brand product at the big-box store. For those who are unfamiliar with the PUR Plus system - it's easy. 1) the main unit attaches directly to your kitchen faucet; 2) unscrew the back the unit to place the cartridge in (there is only one way for it to go); 3) replace back of unit squarely and tightly (to prevent leakage); 4) turn on cold tap water, flip the black lever on the side, and run for about 6 minutes (ALWAYS use with COLD water, NEVER with HOT - the hot watch will damage the filtering elements inside the cartridge). It is the proverbial piece of cake!!

Worked for my PUR. Nice and affordable.

These work very well in our PUR faucet thingie. Drops right in and isn't "nerfed" so it lasts as long as it should.

Clean fast flow. Easy to install and fits our pur filter

Added this filter to the tap at my mother's retirement residence. The tap water tastes awful. The flavour is totally clean with the filter. Excellent product, easier to install and operate. Highly recommended.

Good Quality

Worst filter cartridge I have ever used. I have been using the filter for two years now and ordered replacement filter several times from different suppliers. All were more or less good. But the current product I received is not filtering at all! I get lot of particles in the water and keeping the water over a couple of days, a layer of precipitation is forming on the surface of the container. As I already started using it, not sure can be returned or not. Complete waste of money.

I ordered it because the title says it is for PFM400H. That's not true, it doesn't work with PFM400H.

Works SO much faster than the old OUR brand.
