PD600 Tankless Reverse Osmosis System

Score: 9.0/10 | The Frizzlife PD600 represents the future of home RO systems. No more bulky tanks taking up cabinet space, no more waiting for tanks to refill, no more stale stored water. At $450 with 600 GPD capacity and NSF 58 certification, this tankless system delivers fresh RO water instantly.

This review uses R3's Water Filter Methodology v1.0.0.

NSF 58 certified for reverse osmosis performance. Independent verification of contaminant removal rates.

The high-capacity membrane removes 99.99% of TDS and:

• Lead, arsenic, heavy metals: 99%+
• PFAS/PFOA: 97-99%
• Bacteria, viruses: 99.99%
• Chlorine, fluoride: 95%+

Traditional tank systems store water for hours or days. Tankless delivers fresh-filtered water every time, eliminating potential bacteria growth in stagnant tank water.

The PD600-TAM variant includes alkaline remineralization to restore beneficial minerals and raise pH. Worth the upgrade for better taste.

Six hundred gallons per day capacity means the system produces water faster than you can use it. Fill a glass in seconds, not minutes. No waiting for tanks to recover.

More efficient than standard tank systems (3-4:1) though not quite as efficient as pump-equipped systems (1:1). Acceptable trade-off for tankless convenience.

The included LED faucet displays real-time TDS readings, confirming the system is performing. Visual feedback provides peace of mind.

At approximately 5"W x 18"D x 17"H, the PD600 takes half the space of traditional RO systems with tanks. Fits in smaller cabinets and leaves room for storage.

• Pre-filter (PP+CB): 6-12 months
• RO Membrane: 24 months
• Post-filter (CB): 12 months

Annual filter cost approximately $80-100.

Mid-range for tankless RO systems. Premium brands like Waterdrop run $800+. Budget tank systems start at $150.

The eliminated tank frees significant cabinet space, valuable in smaller kitchens. Hard to quantify but real benefit.

Slightly higher operating costs for the instant-water convenience.

Standard coverage with responsive customer service. Frizzlife has built a reputation for support quality.

Simpler than tank systems because there is no tank to position. Basic plumbing skills required. 1-2 hours for most users.

Turn on the faucet, water flows immediately. No tanks to run dry during heavy use. Fill large pots without waiting.

Filter changes are straightforward with quick-connect fittings. The compact design makes access easier than tank systems.

The Frizzlife PD600 delivers the tankless RO experience at a reasonable price point. Instant fresh water, compact design, and NSF 58 certification make this an excellent choice for families wanting RO performance without the bulk and limitations of traditional tank systems.
