AquaTru Classic Countertop Reverse Osmosis
AquaTru is the gold standard for countertop systems, featuring a 4-stage reverse osmosis process that is officially NSF certified to remove 83 contaminants including PFAS, lead, and fluoride. Unlike many competitors that claim to meet standards, AquaTru provides full performance data sheets backed by IAPMO R&T.
Ingredients & Purity
Uses a mechanical sediment/pre-carbon filter, a high-pressure RO membrane, and a VOC carbon block. Materials are BPA/BPS free.
Scientific Evidence
Certified to NSF/ANSI standards 42, 53, 58, 401, and P473 for PFOA/PFOS. This is the highest level of certification available for a countertop unit.
Brand Transparency
Full performance data sheets are publicly available on their website, detailing the exact percentage of removal for every tested contaminant.
Value Assessment
Higher upfront cost but lower maintenance than many under-sink systems. Filter sets last 6 months to 2 years depending on the stage.
Why Not Alternatives?
Most countertop filters are simple gravity pitchers that fail to remove dissolved solids or fluoride; AquaTru uses a pressurized RO pump that outperforms Berkey and Brita in both speed and contaminant reduction range.
