Home Master TMAFC-ERP Artesian Full Contact RO System

The TMAFC-ERP is another top-quality model in Home Master’s full contact series. It’s an improved version of the TMAFC model above offering some new wonderful upgrades and features. The biggest improvement is the addition of a permeate pump which significantly boosts the unit’s efficiency and puts it ahead of other similar mid-range systems.

Filtration Process

The TMAFC-ERP has got the same 7 stages of filtration as the Home Master TMAFC which includes two high-quality pre-filters, a reverse osmosis membrane, and an additional two remineralization stages.

The 1st stage is fitted with a sediment filter that removes dust, sand, silt, scales, rust and any other particle that’s larger than 5 microns.

The sediment filter is followed by a powerful granular activated catalytic carbon filter in the 2nd stage which takes care of all kinds of chemical contaminants in the water. It clears out chlorine, VOCs, pharmaceuticals as well as chloramines.

In the 3rd stage, we have Home Master’s high-performance Dow Filmtec RO membrane which removes 99% of the remaining contaminants from chemicals to heavy metals to dissolved solids to pharmaceuticals, and many other contaminants like microorganisms.

After the water has been filtered through the RO membrane, it goes through a 4th stage that’s made up of two phases featuring a carbon filter and a remineralization filter.

The carbon filter clears out any residual chlorine and other chemicals while the remineralization filter adds back calcium and magnesium ions into the water to balance its pH level.

This is the first point of the Home Master’s full contact remineralization system and happens before the water is delivered to the RO storage tank.

The second point of remineralization occurs in the 5th stage which is also made up of two phases consisting of a carbon post-filter that helps clear out any odor and tastes picked up from the RO storage tank and a remineralization media that adds small amounts of magnesium and calcium minerals into the water thereby raising the pH level once again.

Like in the Home Master TMAFC model, the first point of remineralization ensures that the water going into the storage tank has a balanced pH to minimize the degradation of the rubber bladder or rather the storage tank itself.

Therefore, the result after the entire process is completed is cleaner mineral water with a much better and fresher taste. The pH value of the final water is around 7.5 to 8.0.

Permeate Pump

Now the major step up to this TMAFC-ERP model from its predecessor, the TMAFC model is the fact that it comes standard with a non-electric permeate pump.

This is a key component that significantly boosts the efficiency of the entire system. It increases the water production rate by almost 50% while at the same time reducing the amount of wastewater generated by up to 80%.

Both of these are really important especially if you are on city water and the incoming pressure is a bit lower than the standard 60 psi. The pump can raise the water pressure from as low as 40 psi but anything below that you will have to get an electric booster pump.

Nonetheless, the bottom line is that with this permeate pump in place, this TMAFC-ERP system will be able to fill the RO tank much faster.

In addition, combined with the larger fittings and tubing that the unit uses, it will absolutely provide a much faster flow rate or water output at the faucet.

You can expect water flows to be about 50% more than that of other ordinary RO systems. Plus the water is also likely to come out slightly cleaner as the pump help eliminate a common condition known as “TDS” creep.

Filtration Capacity and Water Efficiency

The membrane of the TMAFC-ERP is rated to produce around 50 gallons of clean water per day which is the same capacity as the Home Master TMAFC model.

However, with the pump running, its typical output can get closer to 75 GPD. Thereby, if you have a medium-sized family and need a relatively high production rate, this unit will serve you well.

In terms of efficiency, the TMAFC-ERP is no doubt one of the most efficient RO systems out there. This is due to the included permeate pump which helps to both increase efficiency of the system and drastically reduces wastewater production.

Approximately one gallon of water is wasted for every gallon of purified water created. Compared to the average 2:1 and 3:1 ratio of most under sink RO systems in the market, this TMAFC-ERP will definitely keep your water costs low.

The ratio may vary a little depending on your incoming water pressure, but overall if you after an RO system that can help preserve water, then TMAFC-ERP is one reliable option.

Installation and Maintenance

Anyone with basic DIY skills can easily install this unit within an hour or two. The full installation instruction manual is provided and clearly outlines all the steps to install this unit. Home Master has as well made aa several videos that cover the whole installation process. 

The filters and the membrane are long-lasting too and feature the Home Master’s modular design, so maintenance and filter changes will be quick and easy. The four filter cartridges need replacing once every 12 months and the membrane once every 3 to 5 years.

There’s no noise produced either by the pump during operation. It’s extremely quiet with the only noise you are likely to hear is a slight whoosh sound. Furthermore, the pump does not require electricity to do its job.

When you consider all the wonderful and thoughtful additions coupled up with the advanced water filtration technology, it’s only fair to conclude that the Home Master TMAFC-ERP model offers nothing but value for money. If wastewater and pressure is a concern, then this a unit you should consider.

Installation Guide

This video shows you step-to-step how to install a Home Master Reverse Osmosis System.



Do I have to use a specific filter to remove fluoride?

No, this RO system removes fluoride up to 97%, so you don’t need to have another filter to remove fluoride.

Is this RO system the same as the Tap Master TMAFC with an extra permeate pump?

Yes, it is. The permeate pump is the only difference between these 2 RO systems.

Does this RO system come with refrigerator and icemaker tubing kit?

No, it does not. You have to buy them separately.

Does this RO system remove iron?

No. The iron will ruin the system. Home master offers other versions which have an iron pre-filter such as TMULTRA-ERP or TMHP HydroPerfection.
