The Best Reverse Osmosis Drinking Water Filter System

iSpring RCC7P 5-Stage Residential Under-Sink Reverse Osmosis Drinking Water Filter System

The RCC7P reverse osmosis drinking water filter system is identical to the RCC7 in most aspects, but comes with a pre-installed booster pump to bring low incoming water pressure up to the optimal level for the reverse osmosis process. This allows the system to function at its maximum efficiency and water production rate. With the system itself measuring 19 x 14.5 x 5.25 inches and the tank measuring 16 x 11 inches.

The entire unit fits nicely in most under-sink cabinets. The booster pump runs quiet. Only generating a low volume hum that cannot be heard with normal kitchen activity. Also included with the system is a lead-free solid brass body faucet with a high quality brushed nickel finish.

iSpring RCC7AK-UV 7-Stage Residential Under-Sink Reverse Osmosis Drinking Water Filter System

The iSpring 7-stage 75 GPD RCC7AK-UV RO system incorporates polypropylene sediment (PP), granular activated carbon (GAC), carbon block (CTO), and reverse osmosis technologies in the first 5 stages, followed by an alkaline remineralization filter as the 6th stage, then a UV sterilization filter as the 7th and final stage. The alkaline filter adds back healthy minerals that were removed during the reverse osmosis process and can also improve the taste and increase the alkalinity of the RO water.

An RO system with a UV filter is a recommended choice for anyone filtering water from a well or directly from a natural body of water. The UV light is capable of killing bacteria, viruses, and other microorganisms by interfering with the DNA and RNA in the organism’s reproductive cycles. Included with the system is a lead-free solid brass body faucet with a high quality brushed nickel finish. The faucet is typically mounted on the counter as the main output source for the RO water, but output lines can also be connected to your refrigerator output, ice maker, and coffee maker.

Reverse Osmosis Drinking Water Filter System Alkaline APEC Top Tier Alkaline Mineral

The Water Filter System Alkaline ROES-PH75 is a 6-stage 75GPD reverse osmosis system that adds calcium minerals to enhance the water taste for people who prefer mineral water. This system’s mineral cartridge adds only 100% US-made high-purity calcium carbonate to effectively raise pH in the water for those who desire alkaline water.

Other re-mineralization RO systems will claim to add various beneficial minerals back into the water; however, their mineral formulations are often from unknown and uncertified sources that can lead to potential health concern. With the Water Filter System Alkaline ROES-PH75, users will enjoy unlimited great tasting healthy water right at home for drinking and cooking. Save money, time, and from buying costly, bottled water and live healthier with ultra-safe pure mineral water that is contaminant; worry free.

iSpring RCC7P-AK 6-Stage Residential Under-Sink Reverse Osmosis Drinking Water Filter System

The RCC7P-AK has an alkaline remineralization filter to remineralize the reverse osmosis water and neutralize the pH, and also comes with a pre installed booster pump to bring low incoming water pressure up to the optimal level for the reverse osmosis process.

This allows the system to function at its maximum efficiency and water production rate. The system’s alkaline filter contains half red mineral stone and half calcite, giving it the ability to produce bottled-quality mineral water. With the system itself measuring 19 x 14.5 x 8 inches and the tank measuring 16 x 11 inches, the entire unit fits nicely in most under-sink cabinets.

The booster pump runs quiet, only generating a low volume hum that cannot be heard with normal kitchen activity. Also included with the system is a lead-free solid brass body faucet with a high quality brushed nickel finish.

What Are Included- 2 piece of 5 Micron Sediment Filter: With only five micron rating, it is effective in removing dirt, rust and sand particles. NSF certified. – 4 piece of 5 micron Carbon Block Filter: Remove any remaining chlorine and organic chemicals. Further enhance the taste of water. Note: this model, F7-CTO, is for customers who prefer to use CTO in both 2nd and 3rd.

We have another model, F7-GAC, which uses GAC in 2nd stage and CTO in 3rd stage. Stage 5 – 1 piece of Post Carbon Inline filter: This carbon post filter removes objectionable tastes and odors to enhance the quality of your drinking water.Compatible to most RO systems that use 10″x2.5″ filters.

Watts Premier RO-Pure 531411 4-Stage Reverse Osmosis Drinking Water Filter System

This four stage reverse osmosis system consists of a stage 1 five micron Sediment filter that traps particulate matter like dirt, rust, and silt that will affect the taste and appearance of your water.

Stage 2 is a five micron Carbon Block filter that helps ensure a greater reduction of chlorine and other materials that cause bad taste and odors (these are called PRE-filters because they filter in front of the reverse osmosis membrane). 

Stage 3 is the heart of the reverse osmosis system, the RO Membrane. This 50 gallon per day semi permeable membrane will effectively reduce TDS (total dissolved solids), Sodium and a wide range of contaminants such as Lead, Arsenic, Percolate, Chromium, Copper and Radium. It will also remove over 99.95% cysts such as Giardia and Cryptosporidium.

Microline TFC-4 Reverse Osmosis Drinking Water Filter System

The Microline TFC-4 under-sink reverse osmosis system contains a four stage filtration system that supplies up to 35 gallons per day of purified drinking water – right at the sink! The system uses a high quality T.F.C. reverse osmosis membrane with a sediment pre-filter, carbon post-filter and in-line polishing carbon filter. 

The free replacement filter set includes the pre, post and in-line filters. These units include a pressurized polymer holding tank, color-coded tubing for easy homeowner installation, chrome dispensing faucet, and under-sink cartridge assembly that is easily accessed for quick filter removal and replacement.

Also included is an automatic shut-off feature that stops the purified water manufacturing process when the holding tank is full.
