SK99-NEW under sink water filter system activated carbon block targeting chlorine and chloramine reduction
Chloramine & Chlorine Reduction Focus

Chloramine and Chlorine Reduction for Better-Tasting Tap Water

SK99-NEW is a direct-connect under sink water filter system designed for municipal tap water. Its compound activated carbon block targets chlorine and chloramine, two common disinfectants that can affect water taste and odor.

Because SK99-NEW connects to the main kitchen faucet, it is positioned for users who want filtered water for drinking, cooking, washing, and everyday kitchen use without installing a reverse osmosis system.

FAQ

How does the SK99 water filter affect TDS/PPM in water?

TDS is not a professional way to test the water quality, TDS means total dissolved solids. For example, if you put very little salt(NaCl) into the water and test the TDS, you will find the result is dramatically high. The same thing, if your water is full of minerals, the TDS is very high too.

The SK99 doesn’t remove any of the minerals from water, it only stops heavy metals such as Lead, Mercury, Cadmium, and over 70-80 VOCs, and it removes greatly the chlorine from water. Therefore, it is the reason why the TDS you get is not that lower as you expect.

TDS meter testing method is widely used in reverse osmosis systems since the RO filter system also removes minerals from water. If a RO membrane doesn’t have a good performance, the TDS will be relatively high. And if TDS is getting much higher, means it’s time to change the RO membrane.

So please do not use TDS to test any water except Reverse Osmosis System, because the result is meaningless.

How often should the filter cartridges of SK99 be replaced?

About the service life of the filter cartridge for SK99, we would like to recommend you to change the 1st stage every 3-6 months, change the 2nd stage every 8-12 months and change the 3rd stage every 12-18 months. Please notice the service life depends on your water quality and daily usage. All the specification data of the flow capacity that is listed on the sticker is based on actual tests from the laboratory and its provided water.

Why water filter can not be used on well water?

This filter should be used in conjunction with municipally treated drinking water or water that has been properly disinfected before use. The water filter cartridge is manufactured with 0.5micron carbon (top rate) that will get easily clogged up by any type of dirt or settlement from a well.

How can I connect the SK99 filter system to the refrigerator/ice maker?

If you would like your refrigerator or ice maker to have clean and safe water from the Frizzlife filter system, we also have an IMC-2 icemaker kit available on our online store. 

If you have any further questions, please feel free to contact us at support@frizzlife.com

Is SK99-NEW a reverse osmosis system?

No. SK99-NEW is a direct-connect under sink water filter system, not a reverse osmosis system. It should be positioned around chlorine and chloramine reduction, fast main-faucet flow, and easy installation.

What does SK99-NEW focus on reducing?

SK99-NEW focuses on chlorine and chloramine reduction using compound activated carbon block filtration. This makes it suitable for municipal tap water where disinfectant taste and odor are common concerns.

Does SK99-NEW use a dedicated faucet?

No. SK99-NEW connects directly to the main kitchen faucet, which makes it different from SP99-NEW. This is useful for users who want filtered water from their existing faucet without installing a separate drinking water faucet. The tradeoff is that it is not positioned as a dedicated-faucet filter system.

What is the difference between SK99-NEW and SP99-NEW?

SK99-NEW is a direct-connect system that filters water through the main kitchen faucet, while SP99-NEW includes a dedicated filtered water faucet. Choose SK99-NEW when you want a simpler main-faucet setup. Choose SP99-NEW when you want a separate filtered water outlet for drinking and cooking.

What is the SK99-NEW flow rate?

SK99-NEW is designed to deliver up to 2.0 GPM at 60 psi, making it a fast-flow under sink water filter for daily kitchen use. Actual flow depends on household water pressure, installation conditions, and filter condition. This high-flow positioning is important because SK99 supports the main kitchen faucet.

How difficult is SK99-NEW installation?

SK99-NEW is designed for DIY installation and the MD states that setup can be completed in about 10 minutes by following the manual or installation video. All necessary components are included for standard installation. Actual installation time may vary depending on sink plumbing, space, and user experience.

I was skeptical about this, but this was the best decision I have made to drink clean water. You can 100% tell the difference in the taste after installing this. The water flow is great and super strong and it has worked with no issues at all for years. The water is super clear and good. I recommend this to everyone, it is worth the money

Customer photo review of Frizzlife 3-Stage Direct-Connect Under-Sink Water Filter System, SK99-NEW

I bought this to appease my wife. We for many years have solely used a 5 gallon water dispenser for drinking water. Our current house is on a well in town with decent water, but it doesn't taste great. I was a bit cynical when buying this not expecting much but I was wrong. Big, no, massive change in water quality. I can't say how it does with fluoride cuz again we are on a well, but in terms of general taste man this is awesome. I do have 1 slight criticism or recommendation for the manufacturer. I wish you guys provided an adapter to go down to a 1/4 compression fitting for our refrigerator setup. I had to replace my 1/4 water valve with a 3/8 to adapt to this because I couldn't find a reducer easily enough and didn't wanna wait for another Amazon order. So please include a 1/4 adapter and market this to plug into your refrigerator ice/water dispenser. Love it love it love it.

Photo shows M3001 after 6 months in our kitchen in Vancouver BC. We were looking for something to improve the smell but the taste is what sold us. My brother, in south-central Ontario, did only the smell test for his friends and so far 6 of them have installed this to improve the taste of their water which also improved the taste of their coffee and tea.

Customer photo review of Frizzlife 3-Stage Direct-Connect Under-Sink Water Filter System, SK99-NEW

This filter system has been great. I was previously using a brita pitcher and this is on a completely different level. Water tastes sooooooooo much better than Brita water. In the first pitcher you can see that the system fits behind my trash disposal. In the second i am showing that it comes through the regular faucet. I have cold, filtered water for drinking and rinsing off fruits and vegetables, and warm water for doing dishes. This setup works very well, actually. The flow rate is a bit slower than without the filter, but it is not a problem. The water comes through looking perfectly clear in color. This filter does not remove the minerals like a reverse osmosis, but does remove a lot of toxins. This is a nearly set it and forget it setup, i have had no issues. I put it in about 6 months ago, and i am going to replace the first filter insert soon, although i have not noticed any degradation in taste. When i first hooked it up, i compared it to the brita and the water was soooooooooo much better. Highly recommended. I ended up getting a slightly better deal by ordering from the mfr directly on their website.

Customer photo review of Frizzlife 3-Stage Direct-Connect Under-Sink Water Filter System, SK99-NEW

I used this to filter water for a plumed coffee nook, and it is very well made and makes some suitable water for pour-overs (it's no Third Wave packet into distilled water, but it's dang good for coming from the tap)! Make sure that you flush it for about 10 minutes to get any weird tastes out, but overall, I am very happy with it! Oh, and for any of my fellow handymen, make sure to use the included sticker template for hanging it on the wall (unlike myself, who did a LOT of unnecessary measuring and found it in the box afterward ???♂?).

EZ 30 minutes install. Great instructions. All parts fit perfectly. Extra parts. No loss of waters Pressure. After installing and flushing, I gave my wife a taste test: a glass of leading brand reverse osmosis water and the tap water, she could not tell the difference.

Ein tolles Produkt! Die Lieferung war schnell, der Artikel war sehr gut verpackt, und der Preis ist wahrlich fair. Die Installation war super einfach, es ist wirklich alles enthalten, was man brauchen könnte, um den Filter an die vorhandene Wasserinstallation anzuschließen. Das Wasser schmeckt merklich besser, weicher und runder. Ich bin sehr zufrieden!

Customer photo review of Frizzlife 3-Stage Under Sink Water Filter System SK99-NEW, Direct Connect

Only complaint is there are no FLATS on the main S99 cartridge housings or hold knobs , indents, or rubber grip, to hold it when changing filters. You can only put the (way too short!) wrench on the bottom but then you have to hold a large round slippery housing with a cloth. Please add something for future design (too late for this one unless you ship rubber grip rings). I also wish there was a way to pre flush with DI water at the factory that could be dried) . Otherwise water tastes great, I have PFAS in town and this is one of the few rated for that.

Customer photo review of Frizzlife 3-Stage Under Sink Water Filter System SK99-NEW, Direct Connect

For 10 years I used those one stage filters but they just didn’t change the base taste of my water. My installation took a little longer because of my older plumbing but once I figured out how to line everything up WOW. The filtration installations was pretty straight forward. My water test was great. When my mother and sister noticed the difference I knew it wasn’t a false positive. The smell and taste of the water was so different. It just tasted like water should taste, no salt or flavor that interferes with my regular beverages. Never live without FRIZZLIFE again.

Customer photo review of Frizzlife 3-Stage Under Sink Water Filter System SK99-NEW, Direct Connect

Filter was delivered about an hour and a half ago and it installed just fine. Inlet hose allowed for choice of mounting location and there are two outlet hoses (16" or 32") with hose adapters. After the ten minute purge you could easily tell the difference in what our water used to taste like vs now. System is light weight and all I needed was an adjustable wrench, drill, and level (for mounting only, can install without). I'm fairly handy, but have faith that anyone could install this system. Can't wait to test the water purity and compare it to before. Would 100% buy again.

It is very easy to set up. The hoses are nice. The plastic fittings on the actual filter assembly I am skeptical of though for long term use. They sell a different filtration system with metal fittings that I didn't see until I bought this. So far so good and no leaks on initial hookup.

I purchased this filter system to use in my upstairs bathroom as that sink is used a lot for drinking, brushing, washing, etc. The existing water smelled metallic and tasted of metal and chlorine. Installing the filter took less than 10 min from laying out the parts to getting it under the sink connected. Add 10 extra min for flushing out the system. Water now taste slightly sweet (a sign of good minerals) and no longer smells of metals/chlorine.

I have to say the best part about my first Frizzlife unit was how easy it was to hookup.. Now with this new unit SK99 I'm Super excited how much more harmful things it will take out of the water. I do tons of research on these water filters and narrow it down each time to about 3 units. Trust me not having to call a plumber is a big deal.. The quickness of changing cartridges is also a plus. Most people don't even realize how bad their water really is. All of this typing is making me very thirsty. Send me any questions you may have and I will try to answer them.
