LotusDY Under-Sink Purifier
LotusDY opened - view inside filter

The LotusDY is an advanced under-sink water purifier built on TipaTech's patented No-Smosis™ architecture. It's designed to deliver cleaner, better-tasting drinking water while helping preserve naturally occurring minerals — and it features a globally patented, user-adjustable mineral calibration control that lets you fine-tune TDS within a defined range (approximately 100–1000 ppm). Performance varies based on source water quality and operating conditions.

Air Release (with Gas Trapper)

TipaTech Patented Air-Release Technology

The LotusDY uses the same patented TipaTech Air-Release stage family as the T-18 — installed at the top of the filter head with a dedicated gas trapper. It's engineered to help release trapped air and certain undissolved gases commonly present in water systems:

  • Designed to help release undissolved gases including sulfur-related (hydrogen sulfide), radon-related, and chlorine compounds — subject to source water conditions
  • Dedicated gas trapper captures released gases at the head of the filter
  • Helps limit internal conditions that may promote microbial growth within the filtration pathway
  • Supports improved water freshness and overall water quality at the tap
💡 Why it matters: Dissolved gases like hydrogen sulfide (rotten-egg smell) need to be released out of solution rather than trapped on a carbon surface — that's the right physics for gas reduction at residential flow rates. The Air-Release stage handles this at the under-sink point of use.

PP Pre-Filtration (Polypropylene)

Sediment & Coarse-Particle Stage

Polypropylene pre-filter stage designed to help reduce coarse particles such as sand and sediment, helping prepare the water for downstream carbon and membrane stages:

  • Reduces sand, sediment, and visible particulate matter
  • Protects downstream activated-carbon and membrane stages from clogging
  • Contributes to extended cartridge life
3

Activated Carbon (GAC + TIL Rod)

Chlorine, Taste & Odor Reduction

Granular activated carbon and specialized media designed to:

  • Help reduce chlorine and chloramine
  • Reduce color, turbidity, and unpleasant tastes and odors
  • Support overall water quality improvement as part of the multi-stage filtration process
  • Reduction levels may vary depending on source water quality and operating conditions
4

Collector / Contaminant Trap

Closed-Loop Containment

Internal collection chamber designed to capture and contain separated contaminants and suspended waste, helping prevent re-entry into the treated water stream:

  • Isolates accumulated impurities as part of the system's closed filtration pathway
  • Helps limit discharge of separated contaminants back into the environment
  • Supports cleaner output water — no drain-line connection required
💡 Why it matters: Conventional RO systems flush captured contaminants to drain (1–5 gallons of brine per gallon of clean water). The LotusDY's contaminant trap keeps separated material isolated inside the system until routine cartridge replacement — meaningful for water-restricted regions and homes without sub-sink drains.

Advanced GAC — Taste Polishing Stage

Final Carbon Polishing

A final carbon polishing stage engineered to further enhance taste and odor for a cleaner, smoother drinking experience. Optimized to refine water quality after primary filtration for noticeably improved palatability.

Molecular Selector (Ceramic Adsorption Media)

Chemical Compound Adsorption

A ceramic-based media stage designed to support adsorption of certain chemical compounds as part of the multi-stage filtration process:

  • Engineered to help reduce certain organic and inorganic chemical compounds
  • Performance varies depending on source water quality and operating conditions
8

No-Smosis™ Selective Membrane (~0.007 Micron Nominal)

Patented Architecture · Ultra-Fine Filtration

TipaTech's patented No-Smosis™ proprietary membrane operates at nominal performance down to approximately ~0.007 microns:

  • Engineered to help preserve naturally occurring minerals (unlike typical reverse osmosis, which significantly reduces overall mineral content)
  • Designed to help reduce cyst-sized particulates commonly associated with organisms such as Giardia (depending on source water)
  • Reduces rust particles, sediment, and fine particulate matter including microplastic fibers
  • Reduces a broad range of chemical and inorganic contaminants — including certain heavy metals (such as lead and mercury) and certain radioactive-element compounds (including uranium- and thorium-related constituents) — subject to influent water quality
  • Reduces contaminants associated with agricultural runoff (including arsenic-related compounds) and trace pharmaceutical residues, where present
  • Operates without electricity and without a continuous drain-line connection
💡 How it's different: Unlike typical reverse osmosis (which strips minerals and discharges 1–5 gallons of brine per gallon of clean water), the No-Smosis™ approach is engineered to selectively reduce unwanted constituents while helping preserve naturally occurring minerals — and it operates with no intentional wastewater. ~0.007 microns is roughly two orders of magnitude finer than a standard 1-micron filter.

Lower ORP Characteristics

Water Chemistry Feature

The LotusDY is engineered to support lower ORP (Oxidation-Reduction Potential) values compared to typical tap water:

  • ORP is a physicochemical parameter commonly discussed in water science in connection with antioxidant-related properties
  • Lower ORP values are often discussed in scientific literature as an indicator of certain water quality characteristics
  • Achieved through TipaTech's patented design — no chemical additives, no electricity
  • Actual ORP values vary by source water quality and operating conditions
💡 Note: ORP is a water-chemistry characteristic, not a medical claim. Individual perceptions and outcomes may vary depending on source water, usage, and operating conditions.

Hydrogen Nano-Bubbles (Hydronator Module)

Emerging Water-Treatment Technology

The LotusDY's Hydronator module is designed to generate and integrate hydrogen nano-bubbles into the water prior to dispensing:

  • Closed-loop process engineered to help retain dissolved hydrogen in the water
  • Produced without electricity — driven by household water pressure
  • Stable nano-scale bubbles designed for consistent user experience at the tap
  • Dissolved hydrogen levels vary by source water, flow rate, and operating conditions
💡 Note: Hydrogen-enriched water is an emerging area of scientific interest in advanced water treatment and wellness-focused hydration. Ongoing research continues to explore potential antioxidant-related properties; individual experiences may vary.
