Frizzlife Countertop RO (WB99-C)
No-plumbing countertop reverse osmosis: RO-grade filtered water for renters without ever touching the under-sink.
Reverse osmosis is the most thorough home water filtration there is, and the WB99-C delivers it on a countertop: no plumbing, no drilling, no landlord conversation.
The longevity-water debate usually pits reverse osmosis (strips everything, including minerals) against ceramic (keeps minerals) against hydrogen water (mostly marketing). If you land on RO, because your tap tested high for TDS, nitrates, PFAS, or heavy metals, the usual blocker is installation: traditional RO lives under the sink, needs a drain connection, and is a non-starter in a rental.
Frizzlife's WB99-C is the countertop answer. It is a tankless RO system that sits next to the sink and produces multi-stage RO water without any permanent plumbing. The bundle ships with an extra year of replacement filters, and Frizzlife's broader catalog (under-sink RO, the LP365 leak detector) means you can graduate to a built-in later.
The honest trade-off is the one every RO buyer faces: RO removes beneficial minerals along with the contaminants, so heavy RO drinkers should remineralize (drops or a remineralization stage) or rotate in mineral-rich water. If your tap is already low-TDS and clean, a ceramic gravity system like Doulton suits you better. The WB99-C is for people who specifically need RO-grade removal but cannot or will not plumb it in.
Renters and anyone who needs true reverse-osmosis filtration without under-sink installation, especially where tap water tests high for TDS, PFAS, or heavy metals.
Your water is already low-TDS and clean (a mineral-retaining ceramic system fits better), or you want a permanent built-in and can plumb under-sink (Frizzlife sells those too).

Frizzlife WB99-C Countertop Reverse Osmosis System - buyer FAQ
Does a countertop RO work as well as an under-sink system?
Filtration-wise, yes: the same multi-stage reverse-osmosis membranes are used. The difference is convenience and capacity, countertop units skip the plumbing and drain connection (which is why renters choose them) but have a smaller footprint. For drinking and cooking water, a countertop RO like the WB99-C is functionally equivalent.
Does reverse osmosis remove healthy minerals?
Yes. RO removes dissolved minerals (magnesium, calcium) along with contaminants, which is the main critique of RO for daily drinking water. Heavy RO drinkers should remineralize with mineral drops, an electrolyte mix, or a remineralization stage, or alternate with mineral-rich water. If your tap is already clean and low-TDS, a mineral-retaining ceramic filter may be the better choice.
What does filter replacement cost?
The WB99-C bundle includes an extra year of replacement filters, so the first year is covered. After that, RO systems typically need pre/post filters every 6-12 months and the RO membrane less often. Budget a modest annual replacement cost, in line with other RO systems; confirm current filter pricing on frizzlife.com.
