APEC ROES-PHUV75 Overview

Apec ROES-PHUV75

The ROES-PHUV75 is a 7-stage water filtration system that produces 75 gallons of pure water per day. It removes up to 99% of contaminants from the water and has long-lasting filters.

UV sterilization enables the unit to destroy 99.99% of viruses, bacteria, and cysts. The unit also features a US-made cartridge that raises the PH of the water.

It comes with a 4-gallon storage tank that stores clean, pure, and healthy water awaiting use.

  • Premium Long–Lasting Filters

The system boasts premium, long-lasting filters that treat tap and well water. These filters provide unlimited clean, refreshing, and great-tasting water superior to bottled water.

  • Filtration Process

This system filters water in 7 stages and effectively eliminates 99% of contaminants, including lead, arsenic, asbestos, fluoride, heavy metals, among others.

In the 1st stage, a high-capacity polypropylene sediment filter gets rid of all large particles, including sand, silt, dust, rust, among others.

A premium extruded carbon block in the 2nd and 3rd stages removes unpleasant tastes, odors, chlorine, cloudiness, and colors present in your tap or well water.

A high rejection TFC RO membrane in stage 4 removes up to 99% of TDS and other stubborn contaminants like arsenic, fluoride, lead, chromium, radium, and much more.

At this point, all microorganisms are still in the water, and that’s when the UV light comes into play, i.e., stage 5.

Here, Ultra-violet (UV) light, which has a powerful UV lamp, sterilizes, destroys, and kills up to 99.99% of all microorganisms in the water, including viruses, bacteria, and cysts.

In the 6th stage, an advanced coconut shell carbon filter removes any residual taste and odor that could have accumulated in the water while in the storage tank.

By the time the RO water reaches the 7th stage, it’s clean and pure but without minerals. Note that reverse osmosis filtration strips everything from the water, contaminants, and essential minerals alike.

To make the water healthy and tasty, minerals have to be reintroduced back. That’s why the final (7th) stage is very important.

In this stage, a pH + alkaline remineralizing filter adds calcium carbonate into the RO water to increase its alkalinity.

  • Water Flow Rate

The ROES-PHUV75 water production rate is 75 gallons per day, enough for a medium-sized family.

The unit also comes with a 4-gallon tank that holds the purified water awaiting use. This means that you won’t waste time waiting for the water to be filtered before filling your glass.

The system has a filtered water to waste water ratio of 1:3, thus relatively efficient.

  • Installation and Maintenance

When it comes to the installation of this unit, you don’t have to get a plumber to do it for you. With basic DIY skills, you are good to go.

The package comes with all components required for easy installation. A detailed manual will help you set up the unit in minutes.

The system is also easy to maintain now that it comes with long-lasting filters that are easy to replace. The UV filter lasts for 1 year, while the reverse osmosis membrane, post-carbon, and alkaline filters last for up to 4 years.

Aquasana AQ-RO-3.55 Overview

aquasana aq-ro-3.55

The AQ-RO-3 RO unit is a compact, under-sink water filtration system that removes up to 95% fluoride, 97% chlorine, and 99% of other harmful contaminants from the water.

It is the first filter system to combine RO, Claryum filtration, and remineralization.

It is also somewhat bulky, with dimensions of 30 x 50 x 12.5 inches and a weight of 12.3 pounds. This means that you need to consider your under-sink space before paying for the unit.

The system produces 36 gallons of water per day, although this is dependent on temperature and the inlet water pressure.

It comes with a 90-day satisfaction guarantee and is backed by a 2-year warranty on defective parts or poor workmanship.

  • Water Flow Rate

The AQ-RO-3 produces up to 36 gallons of water per day. Although this isn’t much compared to other RO systems that produce 100+ gallons in a day, it’s still enough to supply a small family with enough water.

  • Stylish Designer Faucet

Another worth mentioning feature of the AQ-RO-3 is the stylish designer faucet. It’s made from metal and is 100% lead-free.

You can get the faucet in the finish of choice to match your kitchen décor.

  • Filtration Process

This system filters water in 3 stages to give you clean, pure, and great-tasting water.

In stage one, the RO membrane eliminates most contaminants in the water, including fluoride, arsenic, dissolved solids, nitrates, radium, and bacteria.

The selective Claryum filter (2nd stage) consists of 3 stages; catalytic carbon, ion-exchange filtration, and sub-micron mechanical filtration.

The catalytic carbon media effectively removes common disinfectants, including chlorine and chloramines.

Contaminants like lead, mercury, iron, and heavy ions are removed in the ion-exchange stage, while substances like Giardia, Cryptosporidium are removed through sub-micron mechanical filtration.

In the 3rd/final stage, the remineralization filter replenishes essential minerals like magnesium, calcium, and potassium in the water to make it tastier and healthier.

  • Installation and Maintenance

You’ll face some difficulty with the AQ-RO-3 when installing the outlet faucet if your sink or work surface doesn’t have an existing hole.

With most reverse osmosis systems, you only need a ½ inch or 3/8 inch diameter hole for the faucet. The AQ-RO-3 comes with an air gap faucet meaning that you’ll require a hole with a 1 ½ to 1 5/8 inch diameter. You’ll need a plumber to install the unit for you.

However, if there’s a suitable hole for the faucet in place already, the installation process is a breeze. You just need to follow the step-by-step instructions manual it comes with and contact their customer care support if you need any help.

The filters are also easy to remove and replace during routine maintenance. The RO membrane lasts 1-3 years, the Claryum filter 6 months or 365 gallons, and the remineralizing filter lasts for 12 months.
