6-Pack RF9999 Faucet Mount Replacement Filter for PUR / PUR PLUS (Blue) — NSF Certified
Product description
If you already have a PUR faucet filtration system, replacing filters on time is the part that keeps it doing what you bought it for. This 6-pack RF9999 faucet mount replacement filter is built specifically for PUR’s faucet-mounted setups, including PUR PLUS models and a range of horizontal/vertical mount variants.
On paper, it’s a straightforward “swap and go” solution: it’s NSF certified for chlorine taste and odor reduction (NSF/ANSI 42) and for lead-free material claims (NSF/ANSI 372). It also positions itself as a 3-in-1 style filtration approach with mineral-core filtration, aiming to deliver cleaner water and a refreshed mineral taste profile—without you having to rethink your whole setup.
Key takeaways
This pack is mainly about convenience and continuity. A six-pack format is useful if you don’t want to keep checking for replacements, and if you’d rather plan for filter changes instead of reacting when performance starts to feel “off.”
Where it gets interesting is the filtration claims: it’s tested/certified under NSF/ANSI standards for chlorine taste and odor, and it’s also described as reducing a broad set of substances (including lead) and helping with additional contaminants such as PFAS/PFOA/PFOS per third-party lab testing. That said, you’ll still want to confirm your exact PUR model is compatible—these filters are not universal across all faucet systems.

Where it shines for daily use
In a typical faucet-mounted system, the practical win is what you don’t have to do. You’re not dealing with bulky pitchers or separate plumbing parts—just a replacement filter meant to fit the faucet mount and restore filtration.
The brand describes “instant access to freshly filtered water,” with a filter structure intended to keep impurities out of the flow. If you like the idea of making your kitchen sink water feel more “ready to drink” day to day, this kind of faucet mount replacement tends to make that routine easier.


Also, the durable/long-lasting positioning matters: the filter is described as capable of filtering over 100 gallons, and it’s presented as roughly a regular-use timeline (with one filter equated to about 3 months of regular use in the product messaging). If that matches your household habits, the six-pack becomes a practical maintenance cycle rather than a recurring hassle.
What to know about filtration claims

The listing is clear about NSF certifications: it states testing against NSF/ANSI 42 (chlorine reduction for taste and odor) and NSF/ANSI 372 (lead-free material). It also claims reduction of many chemical and physical substances and mentions heavy metals such as aluminum, iron, copper, and mercury.
There’s also a specific note that RF9999 is tested by a third-party lab for PFAS reduction (PFAS, PFOA/PFOS), alongside chlorine and taste/odor. If PFAS reduction is a key reason you’re shopping, it’s worth paying attention to those details before you buy.
A limitation to keep in mind: the entry covers broad reduction claims, but it doesn’t provide your exact water quality targets or how your results may vary by local water. For peace of mind, consider checking whether your main concern is directly addressed by the contaminants you care about.
Compatibility and installation reality check
This filter is meant for PUR faucet filtration systems with faucet mounts, including:

- PUR Horizontal, Classic, Advanced, Advanced Plus
- PUR Vertical faucet mounts


It also lists many specific compatible water purifier models (including several FM- and PFM- model numbers). The big “yes/no” factor is whether your exact PUR faucet mount model matches what the filter supports.
If you’re not sure which model you have, don’t guess. This is one of those purchases where compatibility is everything—an incorrect match can mean poor fit or it simply won’t work as intended.
Who this is for (and who should skip it)
It’s a great fit if you already own a PUR/PUR PLUS faucet filtration system and you want a replacement filter you can keep on a predictable schedule. The six-pack format makes sense if you don’t want last-minute filter hunts or you’re trying to stay consistent with maintenance.

It might not be for you if you’re using a different brand of faucet filtration system, or if you don’t have a PUR faucet mount setup that matches the listed models. It may also be less attractive if you only need one filter at a time—this is a multi-pack, so you’re paying for future replacements.

When it makes sense


A six-pack replacement filter is usually worth it when you’re thinking in maintenance cycles, not one-off experiments. If your PUR system is already installed and you’re comfortable swapping filters as part of routine upkeep, RF9999 fits that “keep it working” role.

The main decision point is compatibility. If you match your PUR faucet mount model to the listed compatible models, the rest is pretty clear: NSF certifications for chlorine taste/odor, additional lab-tested reduction claims (including PFAS/PFOA/PFOS), and a design aimed at quick access to filtered water.
