The PUR Advanced faucet filtration system (PUR PFM 400H) not only looks like the PFM800, it is the PFM800 without Bluetooth with three different finishes to choose from.

The PUR Advanced faucet filtration system is all about ease of use. You do not even need tools. It fits most kitchen faucets as long as they are not the pull-out or handheld type. The horizontal design saves space and comes in two finishes, chrome and stainless steel.

This newer version of the PUR Advanced Faucet Filtration System has a leak proof connector and the grip also got better. Customers complaint about the older model in the past, which had a problem in this area.

An electronic monitor shows you when it is time to change the filter. This model comes with the improved version of the filter indicator. It is bigger and easier to read plus the battery last 60% longer. That is an important improvement as you can not change the battery.

The PUR Ultimate Faucet Water Filter System PFM800HX is like the PUR PFM 400H, only with Bluetooth and a chrome finish.

The complete system is NSF certified to reduce 72 contaminants. For the removal rates, please check our comparison below.

This is impressive. Other brands are certified for far less. And it means, that you can be sure chlorine, lead, VOC's and other unhealthy stuff is gone from your water.

This model has a MineralClear filter, a filter that adds healthy minerals to your filtered water. And it increases the taste as well.

This Maxtron filter (RF-9999) is the same as in the PUR PFM 400H system. You will have to spend around $56 per year for replacement filters. That is more than for PUR's non-mineral filters, but still less that what some competitors ask for theirs.

You can choose between two spray options by turning the lever on the side.

The PUR Ultimate Faucet Filtration System attaches to your kitchen faucet horizontally. If you are right-handed, the electronic filter life indicator is always in view.

Lefties, you probably want to mount it facing backwards so you can easily reach the lever on the side. Unfortunately, the light would then be hidden in the back. Not so great.

Ok, maybe no everyone needs this,
but the PUR PFM800HX is also Bluetooth-enabled. It can connect to your smartphone. And a free app shows you not only the filter status, but can also track your water intake. It even syncs with your other fitness and health apps.

One of the slight downsides, this system is only available with a chrome finish. Another factor that adds to the relatively high price for this unit.

The vertical-mounted Brita Complete faucet filter system is as easy to install as most other faucet systems. It features a reminder light in front, so you know when it is time to change the filter cartridge.

This is a single light, that changes color from green to amber to red depending on the filter status. Not the ideal solution for you, if you have a red-green visual impairment. PUR has a better design. Read all about it our direct comparison of Pur and Brita faucet filters.

Once attached to your faucet, you have the choice between three different spay options, one of them is filtered water. The handle is not to flimsy and easy to use, even for children.

The filter reduces chlorine (taste and odor), lead, asbestos and some other nasty things found in tap water. An extra layer inside the filter holds sediment back. For your peace of mind, the claims concerning filter abilities are backed by NSF/ANSI standards 42, 53 and 401.

A question often asked is, if the Brita filter removes fluoride. It does not, unfortunately.

One cartridge is good for about 100 gallons of water. And with four months, they last longer than the competition. That reduces the cost for small households. And filter replacement is an easy and fast process.

The DuPont WFFM350 Electric Metered is easy to install with just a pair of pliers. Apart from hand-held or sprayer faucets, most others are compatible with this filter.

An easy-to-read electronic display shows you the exact amount of water cleaned. Caveat is that it operates on a battery you can not replace. Once it dies, the meter is useless. Some users, although otherwise happy with their filters, see this as the biggest disadvantage of this system.

I like the big switch, although it is on the side. And if your left handed you have to choose between easy access or meter reading when you mount it. It is easier to use for children and people with impairments that affect fine motor skills han the Culligan solution. With one turn you can select if you want filtered or unfiltered water. Apart from that, it is hands free.

This filter removes microbial cysts, cryptosporidium, and giardia, reduces chlorine (taste and odor), Particulate Class I, Asbestos, Lead, Mercury, Turbidity, and VOCs. It is certified by NSF/ANSI standards 42, 53 and 372.

The filter cartridge housing and media comes with antimicrobial protection and it is lead-free.

You can get the DuPont WFFM350 Electric Metered in chrome, brushed nickel and white, whatever fits your kitchen best. It comes complete with filter, battery, installation material like two faucet adapters, two washers, and plumbing tape.

DuPont gives you a 4-year limited warranty on this filter. That is a lot longer than the competitors provide you with. They seem to be sure, that their filter housing will not crack. A problem of most other models.

The Culligan FM-25 Faucet Mount Filter is installed easily, you do not need tools for this.

It is available with a chrome finish or simple white (Culligan FM-15A) and allows you to use filtered and unfiltered water with the turn of a switch.

The Culligan FM-25 is effectively reducing chlorine (taste and odor), Particulate Class I, Asbestos, Lead, Mercury, Turbidity, and VOCs. It is certified by NSF/ANSI standards 42 and 53.

Sure, the PUR and Brita water filters can do more, but they are also more expensive. If you don' t have water problems that call for a more effective filter, why pay for something you don't need?

You can filter 200 gallons before your need to replace the filter. That is double the amount of what i.e. the Brita tap filter delivers. Less frequent filter changes save time and money in the long run.

In case of trouble, it is good to know that Culligan gives you a 2-year warranty on this product. You can reach support by phone or email.

Who has the Best Contaminant Removal Rates? Brita, PUR, Culligan or DuPont?

Brita, Pur, Culligan and DuPont faucet water filter contaminants are certified by NSF standards. You as a buyer can be sure, these filters reduce the contaminants as advertised.

If you search around a bit, you can find all this data online somewhere. We took the time and compiled it all in one easy to read comparison table.

You find an alphabetical list of contaminants and the certified removal rates for Pur, Brita, Culligan and DuPont faucet filtration systems.

To make it easier for you, the best removal rate for each contaminant is highlighted.

PUR, Brita, Culligan and DuPont faucet water filter removal rates compiled

If you compare the removal rates, the PUR faucet filter has the best removal rates for a many contaminants. Brita faucet filters are only second best here.

But as always, the devil is in the detail. They all have their strengths and weaknesses. PUR is great at lead removal, while Brita is better at VOC removal. DuPont removes more cysts and chlorine.

The weakest faucet filters for contaminant reduction seem to come from Culligan. They are certified for far fewer contaminants than the others.

Other faucet filtration systems

What about are MANCEL, Waterdrop and similar brands?

Waterdrop WD-FC-01
List Price: ~ 26$
Annual Cost: ~ 22$
Capacity: 320 gallons
NSF Standard: none
Engdenton Faucet Water Filter
List Price: ~ 52$
Annual Cost: ~ 26$
Capacity: 200 gallons
NSF Standard: none

Waterdrop Long-Lasting Water Faucet Filtration System

The Waterdrop Long-Lasting Water Faucet Filtration System uses an activated carbon fiber filter. According to the company, this filter has a 5-micron rating and is 10 - 12 times more adsorptive than ordinary carbon filters.

Well, you just have to believe that as there is no NSF certification.

Same unfortunately is true for their claims it will reduce lead, fluoride and chlorine.

Customers get a 30-day money-back guarantee and limited one-year warranty against defects in materials and workmanship.

Engdenton Faucet Water Filter

The Engdenton Faucet Water Filter is another filter you can attach to your faucet. The company has a website without legal pages and their shop does not have a working payment method for the US but they sell via Amazon.

The information about this filter is lacking a lot of details. And what little they provide is conflicting.

On their listing page for the faucet filter, it says the filter is good for 200 gallons, while on the filter replacement page they write 320 gallons.

So what should be believe?

Additionally, this filter is not certified.

And if you want to know if the great Amazon reviews are real, ask Fakespot Inc. This listing got the worst grade possible from them (checked Dec. 15, 2019).

Unless the company comes up with more, and non-conflicting information, we can not recommend the Engdenton Faucet Water Filter.

Wrap Up

I hope you found all the information you were looking for and feel confident to choose the best faucet water filter for your needs.

The PUR-PFM400H made it to the top of the list again. Great reduction rates, mineral for better taste and a 2 years warranty.

However, the Culligan-FM-25 is still a good, economical choice if your main concern is more clean, healthy water for less per gallon.
