Home High-Flow Under-Sink Water Filter

This compact single-stage under-sink water filter is suitable for sparkling water systems and can also be connected to a dedicated drinking water faucet, the filtered-water inlet of a compatible 3-way kitchen faucet, a sparkling water dispenser, or a compatible instant hot water system.

Its replaceable 3-in-1 filter cartridge combines sediment filtration, charged carbon media, and scale-inhibition media while maintaining a high flow rate of 5–7 liters per minute.

LILIUM FILTER LF-PET200 Specifications

 One Filter for Multiple Kitchen Applications

Dedicated Drinking Water Faucets

Connect the filter to a compatible drinking water faucet for convenient access to filtered water at the kitchen sink.

3-Way Kitchen Faucet

The filter can connect to the separate filtered-water inlet of a compatible 3-way kitchen faucet.

This allows hot, cold, and filtered drinking water to be delivered from one main faucet while keeping the filtered-water pathway separate.

Sparkling Water Dispenser

Use the filter as a pre-filtration system for compatible Liliumfaucet under-sink sparkling water dispensers.

Filtered inlet water can help improve the taste of chilled and carbonated water while helping reduce sediment entering the appliance.

High-Flow Filtration

Many under-sink filters significantly reduce water flow. This model is designed to provide a flow rate of approximately 5–7 L/min, making it suitable for regular kitchen use and compatible appliances that require a stable water supply.

The high-flow design is suitable for:

• Filling drinking glasses and bottles
• Cooking and food preparation
• 3-way kitchen faucets
• Sparkling water systems
• Instant hot water dispensers

Actual flow may vary depending on incoming water pressure, filter condition, local water quality, and plumbing configuration.

3-in-1 Replaceable Filter Cartridge

The replaceable inner cartridge combines three types of filtration media in one compact housing.

PP Sediment Filtration

The PP filtration layer helps capture:

• Rust
• Sand
• Sediment
• Suspended particles
• Visible impurities

Charged Carbon Media

The charged carbon filtration media is designed to help reduce:

• Chlorine taste
• Chlorine odor
• Unpleasant taste
• Unpleasant smell
• Selected organic impurities

Scale-Inhibition Media

The scale-inhibition media helps reduce scale accumulation inside connected kitchen appliances and water pathways.

This can be particularly useful when the filter is connected to:

• Sparkling water dispensers
• Instant hot water systems
• Drinking water faucets
• Multi-function kitchen faucets

The filter helps reduce scale buildup but does not completely soften water or remove all dissolved hardness minerals.

How the System Works

1. Cold tap water enters the filter housing.
2. The PP layer helps capture rust, sediment, and suspended particles.
3. Charged carbon media helps improve taste and odor.
4. Scale-inhibition media helps reduce scale buildup.
5. Filtered water flows to the connected faucet or kitchen appliance.

The system operates using normal water pressure and does not require electricity.

Filter Cartridge Replacement

The internal filter cartridge is replaceable, so the outer housing does not need to be discarded during routine maintenance.

Replace the cartridge when:

• The recommended capacity has been reached
• The water flow becomes noticeably lower
• The taste or odor changes
• The recommended replacement period has passed
• Local water conditions require more frequent replacement

Actual replacement frequency depends on:

• Household water consumption
• Incoming water quality
• Sediment levels
• Chlorine concentration
• Water hardness
• Usage frequency

Always shut off the water supply before opening the filter housing or replacing the cartridge.

Why Choose This Under-Sink Water Filter?

Designed for More Than Sparkling Water

Use it for everyday drinking, cooking, 3-way kitchen faucets, sparkling water dispensers, and compatible hot water systems.

High Water Flow

The 5–7 L/min flow rate supports regular household use without the extremely slow flow associated with some fine-filtration systems.

Compact Single-Stage Design

Three filtration media are combined inside one replaceable cartridge, reducing the number of filter housings required under the sink.

No Electricity or Wastewater

The system operates using normal water pressure and does not require a power connection or wastewater drain.

Replaceable Inner Cartridge

Only the internal cartridge needs to be replaced during routine maintenance, helping reduce unnecessary plastic waste.

Helps Protect Connected Appliances

The sediment and scale-inhibition media help reduce particles and scale entering compatible kitchen appliances.
