Home Master TMAFC-ERP Artesian Overview

The Home Master TMAFC-ERP Artesian is a 7-stage under sink RO system with a daily water production rate of 75 gallons. It is highly efficient with a pure water to waste water ratio of 1:1 and comes with a permeate pump.

The system removes up to 98% of harmful contaminants from the water, including lead, chlorine, TDS, microplastics, pharmaceuticals, and 1000+ more.

It comes in a modular design that eliminates most problems common in conventional models like leaks, high water waste, and slow flow rate.

The unit is a little bulky at 20 x 16 x 12 inches and weighs 14.5 pounds.

  • Design

The Home Master TMAFC-ERP features an innovative modular design that solves most problems associated with tankless systems like canister leaks, slightly acidic water, and service challenges.

The design also makes filter changing easy since each filter is contained in its housing.

  • Water Production Rate

This system has a maximum flow rate of 1 gallon per minute and a capacity of 2000 gallons. It can produce up to 50 gallons of pure water in a day, enough for a small family.

  • Filtration Process

As aforementioned, this system filters water in 7 stages.

In the 1st stage, the pre-filters: dedicated sediment and catalytic carbon, remove large particles like sand and silt and chlorine, chloramines, pesticides, pharmaceuticals, and other chemicals from the water.

The system uses catalytic carbon to remove chloramines and other stubborn chemicals since it’s more efficient than standard active carbon filters.

In the 2nd stage, the unit uses a 0.0001 micron Dow membrane to deal with the toughest contaminants, including arsenic, fluoride, and heavy metals.

Next is the remineralization stage.

The TMAFC-ERP has 2 remineralization filters. The 1st filter remineralizes the water when it first travels into the tank.

This reduces the acidity of the RO water and prevents tank degradation.

The 2nd filter remineralizes the water as it travels to the faucet. It adds calcium and magnesium to the water giving it a spring-like taste.

  • Efficiency

This system is one of the most efficient units you can find. It has a filtered to waste water ratio of 1:1, unlike conventional models that waste as much as 5 gallons to produce a gallon of pure water.

The amount of water waste varies depending on the pressure of the water getting into the system. The higher the pressure, the less water wasted.

 A built-in permeate pump that comes with the system increases the pressure of the incoming water. It helps to reduce water waste and increase efficiency.

  • Installation and Maintenance

The Home Master TMAFC-ERP Artesian is designed to be installed by anyone with basic DIY skills. You don’t need to hire a plumber to install it.

The only problematic situation you will most likely encounter when setting the system up is drilling a hole in the sink top for the RO water faucet.

However, the installation process should be a breeze if the hole already exists.

The package comes with an installation instructions manual that is easy to read and understand. Home Master has also made a series of 6 videos that illustrate how to set the system up.

When it comes to maintainance, the system has some of the long-lasting filters you can find in any RO system.

The pre-filters last one year or 2,000 gallons, and the RO membrane 3 to 5 years.

Filter replacement is easy and takes no more than 10 minutes.

  • Certifications and Warranty

All Home Master TMAFC-ERP Artesian components are NSF certified for safety and performance.

And just like any other RO system from Home Master, this unit is backed by a 5-year limited manufacturer warranty.

APEC’s Ultimate RO-PERM Overview

The RO-PERM is a 5-stage RO system that provides ultra-pure and refreshing water. It can effectively remove up to 99% of contaminants, including VOCs, chlorine, heavy metals, and 1000+ impurities.

The system is designed to work on low water pressures from 30 to 50 psi and comes with a built-in permeate pump that boosts performance. It can produce up to 90 gallons of water per day.

The Ultimate RO-PERM filters are designed, engineered, and assembled in the US hence high quality.

It has long-lasting filters, requires no electricity to operate, measures 15 x 7 x 20 inches, and weighs 27 pounds.

  • Ultimate Permeate Pump

The Ultimate RO-PERM comes with a built-in US-Made made non-electrical pump, which is highly effective for inlet water pressure as low as 30 psi.

The pump boosts the system’s RO performance under normal water pressure between 50 and 80 psi hence the best for homes with low water pressure. It also cuts down the water going into the drain by 80%.

And since it doesn’t use electricity, the pump works with the help of the hydraulic energy of the brine water going down the drain.

  • Filtration Process

The Ultimate RO-PERM filters water in 5 stages.

A high-grade 1- inch, high-capacity polypropylene sediment filter eliminates dust, rust, sand, silt, and other large particles in the first stage.

The 1st stage is very important as removing these sediments protects and prolongs the life of the RO membrane and the system.

In the 2nd and 3rd stages, a premium extruded carbon block 10” removes unpleasant chlorine taste and odor. It also gets rid of cloudiness and colors in the water.

VOCs and other common chemicals are eliminated in this stage as well.

Enter the 4th stage…

Here a high-quality FILMTEC high rejection TFC RO membrane gets rid of up to 99% TDS and contaminants such as chromium, radium, lead, arsenic, fluoride, and much more.

In the 5th and final stage, an Advanced coconut shell carbon filter removes any residual taste from the storage tank.

  • Performance and Efficiency

The system offers superior filtration performance by eliminating up to 99% of contaminants from the water. It effectively removes nitrates, lead, chlorine, VOCs, arsenic, heavy metals, and 1000+ more contaminants.

It also gets rid of odors and colors that can interfere with the taste of your water.

The system is highly efficient in that it provides enough water for low pressure homes. They get a chance to enjoy increased water delivery pressure at the faucet.

The pressure is 2 to 3 times fuller, enabling the system to fill the storage tank faster.

  • Installation and Maintenance

The Ultimate RO-PERM is easy to set up and comes with top-notch JQ quick-connect fittings that don’t require extra lock clips or steps to seal leaks.

You can install the unit in less than an hour with basic DIY skills.

And when it comes to maintenance, this unit uses premium US-made premium filters that last twice as long as filters from other brands.

The fact that APEC provides lifetime support should give you peace of mind when investing in the unit.
