Choosing between these water filtration systems comes down to a practical tradeoff: a new Taishi reverse osmosis system with universal compatibility, or an open-box GE system that lists fluoride removal and a more detailed set of included components. Both use five-stage reverse osmosis filtration, so the decision rests on condition, stated contaminant focus, included hardware, and listed price.
Quick verdict
The 5 Stage Reverse Osmosis Water Filtration System Home Drinking Purifier 75 GPD is listed at USD 109.50, while the GE Under Sink 5-Stage Reverse Osmosis Water Filtration System GXRV40TBN is listed at USD 74.44. That is a listed-price gap of $35.06. Pick Taishi when new condition, universal brand and model compatibility, and chlorine taste and odor removal are the priorities. Pick GE when fluoride is the stated contaminant concern and you want the filter housing, four filters, tank, faucet, and hoses included.

Where each system wins
Taishi has the clearer fit for a new-condition setup. Its listing identifies it as new and specifies universal compatibility for both brand and model. It also lists a 0.0001μm filtration precision alongside reverse osmosis and chlorine taste and odor removal. Those details make Taishi the more direct choice for shoppers prioritizing the listed condition and broad compatibility language.
GE stands out for its stated fluoride focus and component list. The GXRV40TBN lists fluoride under contaminant removal. Its description also names the filter housing, four filters, tank, faucet, and hoses, giving shoppers a concrete picture of the included system pieces. Its lower listed price is another meaningful reason to favor GE when those priorities align.
Product notes
Taishi 5 Stage Reverse Osmosis Water Filtration System Home Drinking Purifier 75 GPD
Choose the Taishi system when a new five-stage reverse osmosis unit is central to the decision. The universal compatible-brand and compatible-model designations are useful for shoppers who want compatibility described broadly rather than around one named appliance brand. Taishi also specifically lists chlorine taste and odor removal, plus a 0.0001μm filtration precision. The limitation is the higher listed price in this comparison, and its described contaminant focus differs from GE's fluoride listing. For a shopper whose priority is a new, universally described reverse osmosis option aimed at chlorine taste and odor, the Taishi listing is the stronger match.
GE Under Sink 5-Stage Reverse Osmosis Water Filtration System GXRV40TBN
The GE GXRV40TBN is the better match for shoppers focused on fluoride as the stated contaminant-removal target. It is also the more component-specific option: the description includes a filter housing, four filters, tank, faucet, and hoses. Since it uses the same five-stage reverse osmosis method as Taishi, that included-parts list becomes an important distinction. Its limitation is the stated open-box condition, which may not suit someone who specifically wants a new unit. Choose GE when fluoride removal and the named set of system components outweigh the preference for a new-condition, universally compatible option.
Final choice by use case
Choose Taishi for a new five-stage reverse osmosis system with universal compatibility language and chlorine taste and odor removal listed. Choose GE GXRV40TBN for fluoride removal and a setup described with a filter housing, four filters, tank, faucet, and hoses. If condition is the deciding factor, Taishi is the clear fit; if the named included components and fluoride focus matter most, GE is the more targeted choice.
