Frizzlife SW20 Direct Connect Under Sink Water Filter System, Reduces 99.99% Lead, Chlorine, Bad Taste & Odor

Q: How does the SW20 water filter affect TDS/PPM in water?

A: 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 SW20 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.

Q: How often should the filter cartridges of SW20 be replaced?

A: About the service life of the filter cartridge for SW20, we would like to recommend you to change the inner core filter per 24-36 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. The more frequently you change the filter, the better water you could get.

Q: Why water filter can not be used on well water?

A: 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.
