Home Master TMAFC-ERP-L Reverse Osmosis System

Designed with the inspiration from the TMAFC-ERP model, the Home Master TMAFC-ERP-L is an efficient and high performing RO system that guarantees to improve the quality and taste of your drinking water.

One of its biggest strength is the high production rate which sets it apart from the other models in Home Master’s full contact systems.

Filtration Process

The TMAFC-ERP-L is loaded with 7 stages of water filtration which is very identical to those of the Home Master TMAFC and TMAFC-ERP models.

The first two stages consist of pre-filters, a sediment filter, and a powerful catalytic carbon filter. These two clear out a good number of contaminants from sediments and particles like silt, sand, dust, and rust to chlorine, VOCs, chloramines, and other common chemicals.

The Home Master Dow Filmtec RO membrane in the 3rd stage removes up to 99% of the remaining contaminants which includes heavy metals like lead and arsenic, microorganisms such as viruses and bacteria, chloramine and total dissolved solids as well.

On its way to the RO storage tank, the filtered water goes through the first phase of the Home Master’s full contact technology. The artesian filter at this stage filters the water again and then re-mineralizes it.

It contains coconut shell activated carbon media that clears out any chlorine, chemicals or other contaminants that slip through the previous stages.

It also has crushed marble which re-mineralizes the water by adding health compounds such as magnesium and calcium into the water to reduce its acidity and help prevent RO tank degradation.

When the water travels from the RO tank, it passes through the second phase of the full contact technology which contains the same artesian filter with crushed marbles and coconut shell carbon media.

The filter removes any possible odor and taste picked up from the holding tank and again adds magnesium and calcium minerals into the water.

These two vital minerals help further raise the pH of the water to more balanced levels of between 7.0 and 8.0. The water that you end up drinking is cleaner, fresh and tastes much natural.

Permeate Pump

Included with the TMAFC-ERP-L is a permeate pump which likes in its predecessor is a key component that works to improve the system’s production rate and efficiency.

It will increase the pressure of the water going into the system as well as the speed of the flow of water at the faucet. This will in turn help boost the production rate by almost 50% and also help bring down wastewater generated by up to 80%.

Same as both the TMAFC and the TMAFC-ERP, the unit utilizes larger fittings and tubing, so the flow rate in the system and at the faucet is much faster, about twice as fast compared to many traditional RO systems.

Filtration Capacity and Water Efficiency

The biggest strength of this TMAFC-ERP-L model is none other than the large capacity membrane it comes with. It can produce a maximum of 75 gallons of pure water each day at 77°F temperature and 70 psi pressure.

That’s a sufficient rate to ensure a constant supply of purified water to meet the demands of a big family and even small offices with 4 to 8 people.

The best part is that when the permeate pump is running, the production rate can increase by up to 50%. It’s cable of outputting around 100 gallons of clean drinking water in a day which is incredible.

The other area where this unit shines is in combating wastewater. The permeate pump plays a role here again as it reduces the wastewater the system produces by 80% bringing the wastewater to pure water ratio to 1:1 which is extremely low and the best you can find in the market.

Installation and Maintenance

Installation is pretty straightforward. The package features everything you need to set the system up and the instruction manual provides a clear guideline of the process.

Maintenance won’t either be a problem. The filters have a long life requiring changing just one every year while the membrane can last up to 5 years.

The only downside although not a deal-breaker might be its large size. Otherwise, the whole system is made to high-quality standards and the pump is relatively quiet when running.

All in all, the TMAFC-ERP-L model is one of the best-rounded under-sink RO systems from Home Master and it’s able to deliver great performance. This is totally worth it if you want a high production rate and fresh-tasting drinking water.


  • Effectively removes more than 1000 different contaminants
  • Raises the pH of the water to a neutral level and make it tasty
  • The permeate pump increases production rate and flow rate
  • Can produce up to 100 gallons of purified water in a single day
  • Extremely low wastewater to pure water ration of 1:1
  • Simple to set up and to maintain due to modular filter design
  • The permeate pump doesn’t require electricity to operate
  • Comes with a 5-year limited warranty


  • A little bit large to fit small kitchen cabinets
