TECHNICAL INFORMATION:

PF-4™ reduction elements, are designed for use with Doulton ceramic filtration elements to adsorb the following four unwanted elements most commonly found in drinking water.

Please note: These filter elements have a specific threading size that will only fit to ceramic Doulton™ and Berkefeld™ Filters. If you are unsure which system these are designed for use please contact us on (07) 55 333 611

MTBE (Methyl-tertiary-butyl-ether)
Fluoride
Lead
Arsenic

PF-4™ filters are also designed to adsorb:

DBCP (Dibromo-chloro-propane)
THMs (trihalomethanes)
Herbicides & Pesticides
Heavy Metal ions

Fluoride: Testing for fluoride was based on 20-30ppm of the ion in the influent aqueous solution at a flow rate of no more than 3 gpm (11 lpm) per cubic foot of media. Results of 95% reduction). Under optimum conditions, effluent concentrations of less than 50 ppb were readily achieved (>99.75% reduction).

Please note that the average level of fluoride in Australian town water supplies is 1ppm. These filters are what we believe to be most effective as they are tested at a much higher level and are guaranteed for the capacity of the filter. When using these elements in a gravity system, such as our stainless steel or ceramic systems, these filters have longer contact with the media and are therefore more effective than when tested under a higher flow rate. 

Arsenic: This product uniquely targets the entire family of arsenic oxide anions as well as the arsenic cations.

Lead: Tests have shown that when 7,500 litres of influent water at a concentration of lead of 150-200 ppb pass through 200 grams of media at a flow rate of 1gp , the lead level was reduced to less than 1ppb (99% reduction).

The fuel additive MTBE (Methyl-terteiary-butyl-ether): Berkey PF-4™ elements are manufactured to exceed ANSI/NSF standard 53 which requires that MTBE be reduced by at least two thirds from an influent rate (water going out) of less than 5ppb (>95% reduction*) *Actual capacity is dependent on the presence of other competing contaminants in the source water. High levels of total organic carbons and volatile organic compounds may reduce the capacity and efficiency of the elements.

For use with Durand Fluoride Reduction Systems or British Berkefeld Stainless Steel Systems.  To be used in conjunction with a Doulton Super Sterasyl Ceramic Filter.

Note: Durand Original Systems do not have enough clearance in the storage chamber to accommodate the PF-4™ element.

REPLACEMENT:

Under normal conditions it is recommended that each PF-4™ element be replaced after 1,000 litres (or 2,000 ltrs if you are using two elements in your system). If you consume about 5 litres a day of filtered water you would need replacement every 6 months in a system using 1 filter and 1 element at a time. Every 12 months if using a system which uses 2 filters and 2 elements. Actual capacity is dependent on the presence of other competing contaminants in the source water. High levels of fluoride, arsenic and heavy metals may reduce the capacity and efficiency of the elements.

INSTALLATION PROCEDURE

PF-4™ elements must be washed and primed before USE.

WATCH A SHORT VIDEO ON THE INSTALLATION PROCEDURE HERE

Please note: This video demonstrates the below procedure with a PF-2 element (For Black Berkey elements). The procedure is the same for PF-4 and PF-2 elements.

PRIMING PROCEDURE

The media in your PF-4™ contains micro fine process dust that can cause the filtered water to have a bitter taste. To dislodge the process dust from your element, it is necessary to prime each element. To prime your element use the following procedure:

  1. With blue caps in place wash the exterior of each element with mild dish soap.
  2. With clean hands, remove both blue caps from the end of each element.
  3. Place the rubber washer (priming button) onto one of the elements and align the hole in the button with the hole in the element. Hold on to your priming button for further priming.
  4. Press the priming button up against a sink faucet so that the priming button creates a seal between the faucet and the PF-4™ element.
  5. While holding priming button against faucet (place thumb on top of faucet to apply pressure and create a better seal) Turn on the cold water gently, allowing water to fill the cavity of the PF-4™ element and discharge for at least 20 seconds or until water runs clear whichever is longer.
  6. Turn the PF-4™ element the other direction and prime the other end repeating steps 3-5. The element has now been primed.
  7. Repeat the above steps with the second PF-4™ element. 

INSTALLATION AND USE

  1. Assemble the water filter as per system assembly instruction.
  2. On the underside of the upper chamber (holding the ceramic filter/ filters), locate the stem of each ceramic filter, making sure the wing nut of the filter is in place and hand tightened.
  3. With clean hands take a primed (caution read directions above "priming procedure", before installing) PF-4™ element , with the water flow arrow pointing away from the upper chamber. Screw the PF-4™ on the protruding thread of the ceramic filter 3-5 revolutions.
  4. DO NOT SCREW MORE THAN 5 REVOLUTIONS OR YOU MAY CAUSE DAMAGE TO THE INTERNAL SCREEN.
  5. When complete, seat the upper chamber on top of the lower chamber. Fill upper reservoir or container.
  6. When the lower reservoir is full, discard the first batch of water, which may contain some process dust.
  7. When upper chamber is full of water the PF-4 will be immersed in the stored water area.

They leak and the don’t last, but they’re sleek.
Color: Black
I love the shape of this flosser, that aspect is perfect. That’s the reason I’ve bought (3) over the years. But unfortunately, I’m done. Looking for a new gig. Every single one has leaked water. I just dealt with it. But the year and a half life they last is the deal breaker. Buy the insurance. You will use it. They simply do not last forever.

Perfect for home or traveling
Color: White
This is my second water floss, product, and by far the best. Yes, the water reservoir is not as large as some of the others, but it is perfectly adequate. Easy to use, has three different settings, that are easy to change. Definitely enough power to get all the food out from between my teeth. I use this when I had braces, and I use it now with my retainer, so that my teeth are always clean. I like the design, and the fact that it doesn’t have a tube to suck the water. The charge lasts for an extended period of time and recharging is very quick. I can go two to three weeks, and it’s still got a good charge to it. Highly recommend.

Surprisingly Great!
Color: Black
I’m writing this review because I am actually Overly satisfied with this product. There are many high quality brands that have similar “water flossers” with high price tags. The price on this was relatively inexpensive so I decided to try it knowing Amazon’s great return policy. I’ve had it for just over a week and I’m borderline addicted to how good my teeth feel after using this along with normal brushing and mouthwash. It’s a legit “just left the dentist feeling” I can say for the price it is a good value and works great. This comes with a few extra standard heads, a specialized head with small brush for braces and a tongue scraper. I primarily use the standard head which is just a small jet that allows you to shoot the water stream between your teeth. I also have used the tongue scraper just to try it and it’s not bad. Allows you to scrape your tongue while a stream of water cleans and rinses. Anyone who flosses regularly knows it sucks and can be gross. Let’s face it, you are ripping old food out of your teeth. It’s a necessary evil for a healthy mouth. I used the small plastic floss picks for a while and they do a decent job. Dental hygienists usually argue it’s not the same but I think it’s better than not flossing at all. Now my routine is a quick floss with the floss picks followed by this water flosser - and it’s fantastic. The unit is well made and has a few different modes. I stick to the standard mode which is a constant jet of water. It’s aggressive and can be intimidating at first so here are some tips I think will help: 1. I use slightly warm water. Cold water blasted at your teeth is not fun. Warm water is a way better experience. The reservoir is easy to fill right from the sink. 2. It will take a couple tries to figure exactly how to use it. If you just hit the power button it will jet water everywhere before you get it in your mouth. My suggestion is put it in your mouth, aim the head between your teeth, close your mouth and then hit the power button. Once it starts you just move it from tooth to tooth between your teeth. Once you get the hang of it it’s great. I do my top teeth, spit out, then do the bottom row and spit out. I follow it up with brushing and mouthwash. Literally the fresh from the dentist feeling. 3. The reservoir is small so it runs out quickly but it’s so easy to refill I wouldn’t call it an issue. If it were larger it would be bulky and the other brands that have a big tank and hose are just too much to deal with. After a week of using I can quickly do all my teeth with one fill. I usually do a second round as well because im addicted. 4. Be careful of turning it on when it’s not in your mouth. The jet is strong and could shoot you in the eye. Not joking. 5. It may be awkward at first but once you get used to doing it you get better at it and it’s much easier. The power button is your friend. I turn it on and off to control the jetting to get more time out of the reservoir and to prevent spraying everywhere. 6. It has a USB charger and it works well. It seems to go almost a week without charging and I use twice a day sometimes - because I’m addicted. Overall it’s great value for the low price. I’m Not sure how long it will last but I would definitely get another one if this one failed.

Long-Term Review – Still Works Like New After Months of Daily Use
Color: Black, Color: Black
I purchased the Nicwell Water Dental Flosser in June 2024, and I’ve been using it consistently ever since. I wanted to wait before reviewing so I could speak to durability and battery life — and I’m glad I did. Performance: This flosser does a very thorough job cleaning between teeth and along the gumline. It removes debris that traditional string floss sometimes misses and leaves my mouth feeling noticeably fresher. The pressure is strong enough to deep clean but not uncomfortable. Modes & Usability: The different modes are useful depending on how sensitive your gums feel. Switching between them is simple, and the controls are straightforward. It’s lightweight and easy to handle, even in the shower. Battery Life (Very Impressive): One of the standout features is the battery. Months later, it still holds a charge just like it did when I first bought it. I don’t have to recharge it often, and charging is quick and easy. Build Quality: The unit feels solid and well-made. I haven’t experienced leaks, power issues, or performance decline. It still operates like new. Who It’s Great For: • Anyone who struggles with traditional floss • People with sensitive gums • Those wanting a portable option for travel • Anyone looking to upgrade their oral hygiene routine I haven’t had any problems with it, and it’s been consistent since day one. For the price and quality, I think it’s a great investment in daily dental care. Highly recommend.

Some drawbacks but overall Good- BUY SEPARATE CHARGING CORD
Color: Black
I have had this for about a week now and here are my takes so far: You have to order the charging cord separately which is weird, but I was able to get out delivered quickly with Amazon Prime so just know to do this when you order. Pros: The price! The water tank is surprisingly large compared to WaterPik and you can definitely use it for longer to clean because of this. There are lots of different options for water strength and different tips that come with the device In the first week it has worked fine. Cons: It is a little too easy to accidentally hit a button and change the water pulse when you are holding it- I have to be very conscious of where my hand is so I don’t get the super strong flow (it is very strong) The little door where you add water to the tank is at the bottom and seems like out would be easy to knock it off accidentally when open. I did do this once but nothing broke so I was able to snap it back on easily. I dropped the device about six inches into my sink (all of these devices can be slippery) and the tank got nudged off, but I was able to easily re-attach it so no real problems there. There is a little detached plug you use to cover the charging connection and it seems like it would be so easy to lose the little thing. 🤞🏼 OVERALL: I would buy again as overall it works well, and the last WaterPik I bought died after 2 weeks (so I don’t trust those anymore). Just be mindful of how you hold it, and watch out for the little tank door and the little rubber charging cover!
