Benefits of Our RO:

Choosing the Right Level of Protection

Our high-efficiency Pure Haven Reverse Osmosis (RO) systems deliver exceptional water purity by utilizing a specialized semi-permeable membrane that forces water under pressure, effectively removing up to 99% of dissolved contaminants and impurities. Installed conveniently under the kitchen sink, these system provide a dedicated source of ultra-pure drinking water directly at the tap, eliminating the need for bottled water. 

These advanced RO systems significantly reduce Total Dissolved Solids (TDS) along with a wide range of harmful contaminants, including lead, arsenic, fluoride, and chromium. The result is crisp, clean, and refreshing water that meets or exceeds bottled water quality, right in your home. 

Designed for both performance and practicality, our RO systems are a trusted choice for professional installers and discerning homeowners alike. Reliable engineering ensures consistent high performance with minimal maintenance, while offering efficient water recovery. Whether you are a homeowner seeking maximum protection for your family or a water quality professional recommending the ultimate solution, these system represents the gold standard in residential, commercial, and industrial drinking water purification.

• Superior Contaminant Reduction: In addition to TDS, lead, arsenic, fluoride, and chromium, our RO systems effectively removes nitrates, pesticides, pharmaceuticals, volatile organic compounds (VOCs), and other microscopic impurities that many standard filters miss.
• 
  
• Exceptional Taste & Odor Improvement: By stripping away dissolved solids and chemicals that cause unpleasant tastes and odors, the system delivers crisp, refreshing water that enhances the flavor of coffee, tea, and home-cooked meals.

Supercharge your under-sink reverse osmosis system with the 5100QP 5-Stage RO Module. This complete 100 GPD module features a built-in 24V booster pump that ensures optimal pressure and maximum water production, even in low-pressure homes.

5-STAGE PURIFICATION PROCESS

Stage 1: Sediment Pre-Filter
A 5-micron polypropylene sediment filter that removes dirt, rust, sand, silt, and other large particles. This protects the subsequent filters and the RO membrane from clogging.

Stage 2: Carbon Pre-Filter
Removes chlorine, chloramines, bad tastes, odors, and many organic contaminants. It also helps protect the RO membrane from chemical damage.

Stage 3: Second Carbon Pre-Filter
Provides additional removal of chlorine, VOCs, and organic compounds for enhanced protection and better water quality before the membrane.

Stage 4: Reverse Osmosis (RO) Membrane
The heart of the system. A high-rejection Thin Film Composite (TFC) membrane (100 GPO rating) that removes up to 98% of dissolved solids, heavy metals, fluoride, nitrates, arsenic, and other contaminants down to 0.0001 microns.

Stage 5: lnline Carbon Post-Filter (Polishing Filter)
A final activated carbon filter that polishes the water, removing any residual tastes or odors and delivering fresh, great-tasting drinking water.

Add an extra layer of protection with the Polaris UVI-1 / UVA-1C Ultraviolet Sterilizer. 

This compact 1 GPM UV unit is the perfect optional add-on for any under-sink RO system to provide advanced disinfection.

How it Works: Installed after the RO membrane (typically after the polishing filter), the UVI-1 uses powerful ultraviolet light at 254 nm to deactivate and destroy 99.99% of harmful microorganisms, including bacteria, viruses, E. coli, cysts, fungi, and algae, without using chemicals, adding taste, or altering water chemistry.

The LC300 is a compact, high-efficiency 4-stage reverse osmosis water purification system engineered to produce up to 300 gallons per day of clean, great-tasting water for residential and light commercial use. It delivers up to 97% rejection of total dissolved solids (TDS) along with sediment, chlorine, chemicals, and other contaminants through sequential sediment pre-filtration (5 micron), carbon block pre-filtration, a high-rejection RO membrane, and final activated carbon post-filtration for refined taste. The system includes an integrated booster pump, low and high-pressure switches, solenoid valve, and pressure regulator for reliable automatic operation that shuts off when the storage tank reaches approximately 40 PSI, protecting components and conserving energy. Its space-saving design (17.5" W × 32" H × 10.5" D), quick-connect fittings, and straightforward installation make it ideal for dedicated locations, providing dependable purified water for drinking, cooking, ice, and food preparation with simple annual filter changes and long-term durability.
