5 star
I got this MK99 around 2 weeks ago, went with Frizzlife brand search and directly bought this one as my friend told me that I might want to try this filter, so yes, she got one and now I have one too. Ok, I will share for now why it’s worthy a 5 star! Star 1, the packaging of the product is with a decent pack, not luxury but very neat! LOVE Star 2, with the help of instruction and the YouTube installation video, the installation is without a hitch, it’s amazing that I don’t need a plumber to do this, Installation took me 7 minutes and 16 seconds, LOVE Star 3, the water taste is just like a real water it should be, orderless and taste great! 1000 times better!! Use test kit for the chlorine and LEAD, it’s just work as described. LOVE Star 4, for how convenient it is to replace the filter, the cost of replacement is very reasonable, no more Brita and no more struggling for the refrigerator filter. I tried twist off the container without shutting off the valve, it’s amazing that no water come out from the head, what a technology!! LOVE Star 5, I suppose this will for the customer service, my first test was using TDS meter, not happy with the result, emailed the company and they are sooo quick to help me out and NOW I KNOW WHY, searched from google as well, TDS is only used for Reverse Osmosis system and to check how good the RO does, but RO has no mineral in water , that’s why. The water from the Frizzlife MK99 leaves all essential minerals in the water, which is very good!! LOVE Overall, I highly recommend! And hope my review is helpful for everyone who is still hesitating whether to buy.

Works Wonderfully; Pays for Itself!
Moved into a house where the well is out in a lake, and despite the well being filtered, having a standard sand filter and water softener on top of it for the house, the sink water always tasted nasty. Part of that was due to the anti rust stuff the softener salt had (which we discontinued), and just the nature of the lake water. Well, let me tell you, the picture I attached is the filter after just short of six months of usage! Just swapped it out tonight as the sink had gone down to a trickle this week. The pic doesn't do it justice how much junk it really filtered out! The taste was gone instantly and the water began to taste great. No odd particulates, odors, etc. were coming out anymore. We use the cold water a lot in our home. Aside from dishes, we make iced tea, fill up the tea kettle, coffee maker, fill up the ice cube trays, etc. What a world of difference in quality and taste this filter made! Let me also tell you, I HATE plumbing related work when I have to do it myself. I will do electrical work all day long, but plumbing is a chore. This was so ridiculously easy to install, I thought I got it wrong the first try. Well it was a breeze to install AND change the filter out. I'm so impressed with this filter I'm bothering to do this review! Great filter, worth every penny!!!

Mixed bag - good initial flow but required modifications and filters extremely difficult to change
I've had this filter for 6+ months now and felt like it was time to put in a review. First things first, you should never trust a review from someone who just installed a consumable system like a water filter, as it will typically perform very well initially and issues arise down the line. Let's start with the good here: It's inexpensive for the advertised flow rate - this is one of the only filters on the market that advertises over 2gpm, and it is capable of reaching that with a brand new filter. However, at least with our water source (New York City), that performance degrades SUBSTANTIALLY after a few weeks, to the point where it gets down to a trickle. Frizzlife stood behind their product and sent a second filter, but the same thing happened again within a few weeks so it seems our water's particular composition and this type of filter media don't play nicely together. I solved for this by installing a pressurized water tank in line after the filter stage, more commonly used with Reverse Osmosis systems (but works perfectly here as well) so that the first quarter gallon is full speed ahead even with the water supply shut totally off (and the tank refills as it dispenses) - this has resolved my flow rate issues permanently. Good quality metal hoses are included, but unfortunately that's more of a problem for me because my existing water filter connection requires push to connect plastic fittings. I fashioned an adapter from a 3/8 NPT to 1/4" push-to-connect after the tank stage to address this, but it would be nice if they included a few adapters in the box because they're surprisingly hard to find but cost next to nothing. It's definitely doing something! Take a look at the picture above, about 5 months after the filter was installed it's absolutely disgusting looking with the color of a cigarette filter. This will not lower your TDS reading, and they're very clear about that, but the drinking water it produces tastes good and clearly lacks the nasty stuff it's pulled out above. Now, let's talk about the bad parts: This is only a direct connection if you have the rare filtered water spout that accepts a 3/8" NPT or 1/2" NPT connection, as these are the only connectors and adapters provided. If you look at any of the most popular filtered water faucets sold on Amazon, the vast majority use 1/4" quick connect push-to-fit connections. Whether or not you think there are long term reliability issues with such connections, that is what most people already have in place, meaning you're headed to the hardware store to try to rig together some kind of adapter, which is likely to have more leak potential than a direct connection. They should at least include adapters they've tested and endorse in the package to avoid this. Removing the filter assembly from the bracket is super easy, it rotates out and twists off - anyone can do this. However, you haven't changed your filter at that point... this is not a drop in replacement - they sell the inner filter medium by itself, and include a special plastic wrench for opening the filter assembly housing to replace the medium. This works great when it's new, but when I went to change filters (see above) it would not budge under any circumstances - I put it in a vice and used a mallet to the point that the plastic wrench started to strip. I ended up having to buy a set of oil filter pliers to counterhold and twist, and finally was able to open it, but this is exponentially more difficult and time consuming than a system like 3m Filterete where the replacement filters come ready to screw in. I get that it saves plastic and likely benefits the environment, but man, their implementation is not up to the task. Tl;dr? Good performance for the money but changing filters sucks and it doesn't come with what you need to connect to the vast majority of filtered water faucets, ice maker lines and other things you might need filtered water for. I wouldn't buy it again but I'm also not going out of my way to replace it now that it's plumbed in.

This is a review for both MK99 and MP99: I bought MK99. I was very impressed with it, so I decided to buy MP99 and replace my existing designated water spigot that has Rainfresh ceramic filter system. Rainfresh is a very complicated system. When it was time to replace the ceramic filter, I thought of buying MP99. MP99 was a little expensive, but it was simpler, very simple to install. From my main water supply, the water runs through MK99, then using the T-valve that comes from MP99, i used it to run the water from MK99 to my main kitchen faucet, then the other line to MP99, to the spigot. My main faucet is filtered once, which is good enough for me, but the water to my spigot is filtered twice. I had a request to the seller to make my system more efficient. I will not go into details, but when I emailed the seller, I got an immediate reply in a matter of minutes. WHAT THEY OFFERED, WAS FAR AND BEYOND WHAT I WAS ASKING. Amazing customer service. The prompt reply and the solution they offered were phenomenal. I AM EXTREMELY HAPPY WITH MY NEW WATER FILTER SYSTEM, much simpler than my Rainfresh ceramic system. EXTREMELY HAPPY AND OUTSTANDING CUSTOMER SERVICE. Btw, this doesn't bring the TDS to zero, bec it only filters heavy metals and let minerals run through. Also, for those saying that it doesn't have certification. YES, IT DOES. It is certified by IAPMO R & T, which is the certification in NORTH AMERICA!! CHECK IT OUT, THEY HAVE A WEBSITE, and you can see that FRIZZLIFE is certified. LOVE, LOVE, LOVE THIS!!

Awesome product. I could taste the difference in the water instantly. Installation was pretty straightforward. Just need to follow the steps in the instruction manual.

Wir trinken fast ausschließlich Wasser aus der heimischen Wasserleitung. Zum einen ging mir die Schlepperei gegen den Strich, und zum anderen ist es unter Umständen auch noch günstiger. Laut unserer Stadtwerke haben wir sehr gutes Wasser was aber sehr Kalkhaltig ist. Das sieht man sehr schön am Wasserkocher und an der Kaffeemaschine. Das war aber nicht der Grund warum wir uns nun einen Wasserfilter gekauft haben. Jeder weiß das Wasser das strengste kontrollierte Lebensmittel ist was wir haben. Leider kontrolliert aber keiner die Belastung des Wassers die zum Beispiel durch alte Rohre im Haus entstehen. Darüber habe ich mir allerdings auch noch nie Gedanken gemacht. Für mich ist es selbstverständliche den Wasserhahn aufzudrehen und davon zu trinken. Wie dem auch sei. Wasser gut, Haus alt = vielleicht schlechtes und ungesundes Wasser? Laut einen Bericht auf einer bekannten Internetplattform sollte man Leitungswasser nicht in großen Mengen und wenn doch nur abgekocht zu sich nehmen. Ersthaft? Das ist mir zu viel Stress. Also mein Smartphone raus und schauen was Amazon in dem Bereich so anbietet. Denn das Netz ist voll davon. Und da ich mich stark auf Rezessionen fokussiere, und schon diverse mal auf die Fre..e gefallen bin, schreibe ich immer ein wenig mehr als es hätte sein müssen. Nun denn. Welcher Filter sollte es sein? Wie gesagt es gibt eine große Auswahl von Wasserfiltern. Auch die Preisspanne ist groß Er sollte unter der Spüle in der Küche seinen Platz finden. Anschlussschläuche sollten dabei sein. Wandmontage wünschenswert ab nicht zwingend. Der Aufbau sollte leicht von der Hand gehen, der Filter wechsel sollte ohne größere Umbauten von statten gehen. Ach ja die Folgekosten durch neue Filter sollten überschaubar sein. Beim stöbern bin ich bei dem Wasserfilter von Frizzlife hängen geblieben. Eine schöne Anzeige mit vielen Infos. Da der Filter grade im Angebot war landete er im Einkaufwagen und einen Tag später bei mir. Im Karton der Filter der in Folie eingeschweißt ist, alle Leitungen, einen Adapter für ein anderes Zollmaas, Teflonband zum Abdichten, Schrauben für die Wandhalterung, und zwei Schlüssel zum öffnen des Filters, und den üblichen Papierkram. Die Aufbauanleitung ist bebildert und wird in diversen Sprachen angeboten. Da der Aufbau aber selbsterklärend ist, und am Filtergehäuse steht was der Ein und was der Ausgang ist, werden viel Personen keine Anleitung benötigen. Ich habe für den ganzen Aufbau ca. 15 Minuten gebraucht was ich völlig in Ordnung finde. Der Hersteller gibt vor den Filter 10 Minuten Wasser durchlaufen zu lassen. Also Alexa stelle einen 10 Minuten Timer. In der zwischenzeit konnten ich prüfen ob es undichte Verbindungen gab. Glücklicherweise gab es aber keine. Den Halter mit dem Filtergehäuse in dem sich das eigentliche Filterelement befindet eben noch mit den mitgelieferten Schrauben an der Wand befestigen, dann ist die Installation beendet. Und nu? Nichts. Ist der Filter durchgespült kann man alles das machen was man sonst auch macht. Wasser in die Kaffeemaschine oder den Wasserkocher füllen, Essen damit kochen oder trinken. Ja ich weiß macht Sinn. Aber kann man Unterschied erkennen, schmecken wat ever? Zum Geschmack. Ich habe mich nie über unser Leitungswasser beschwert es war okay für mich. Nun habe ich allerdings das Gefühl das es anders schmeckt. Das bezieht sich auch auf Kaffee oder Tee. Der Geschmack ist mMn nach weicher. Wasser welches im Topf oder im Wasserkocher heiß gemacht wird hinterlässt keinen weißen Rand mehr. Zufall? Der Hersteller gibt an das 99.99% der Verunreinigungen entfernt werden, und alle wichtigen Mineralien enthalten bleiben. Schwermetalle, Chlor usw. werden reduziert. Das sind natürlich alles schöne Worte. Kann ich allerdings nicht so ohne weiteres bestätigen. Ich bin allerdings sehr zufrieden mit dem Filter. Das Wasser schmeckt mir besser und auch Kalk scheint nur noch in reduzierter Form vorhanden zu sein. Bleiben noch die Folgekosten. Im Gehäuse, welches sehr stabil daher kommt, befindet sich das Filter Element. Der Filter hält zwei Jahre. Empfohlen wird nach 6-8 zu tauschen. Das zweier Set kostet knapp 40€. Der Tausch des Filters ist sehr einfach. Dazu einfach das Filtergehäuse knapp 45 Grad nach Links drehen. Wasser abdrehen muss man nicht. Mit der mitgelieferten Schlüsseln die Deckel abschrauben und das Filterelement wechseln. Bin zufrieden, kann es weiterempfehlen.

I use a similar filter system in my motorhome & decided to purchase & install a domestic under-sink version on the cold water tap in the kitchen. Installation was straightforward and after flushing water through for 3 minutes the result was impressive. The water tasted fresh. I conducted a blind tested on my partner & she agreed the taste had improved.
