[Home Master] Tapmaster TMAFC Reverse Osmosis System

The Home Master TMAFC reverse osmosis system is a revamp from Home Master’s standard RO systems as it comes with new features that greatly boost its performance.

It’s a quality RO system that effectively filters and remineralizes the source water to produce safe, clean and better-tasting drinking water. This is our top pick under Home Master’s full contact under sink RO systems.

Filtration Process

The TMAFC is an under sink RO system designed to provide a 7-stage filtration process using only three physical filters and a reverse osmosis membrane. This is made possible by the full contact technology which has multiple stages that bring about the 7 phases of filtration.

In the 1st stage is a 5-micron quality sediment pre-filter that traps larger particles that are visible to the naked eye. It removes dust, sand, silt, rust and other particles and sediments that are likely to clog the subsequent filter stages.

The 2nd stage consists of a 5-micron granular activated catalytic carbon pre-filter which is a powerful filtration media that removes most of the chemical contaminants like chlorine, pharmaceuticals, and VOCs. It clears out cloudiness, unpleasant tastes, odor and even persistent disinfectant chemicals like chloramines.

In stage 3 sits a 0.0001-micron RO membrane which removes up to 99% of the remaining contaminants in the water.

This very effective membrane will remove fluoride, nitrates, total dissolved solids, cysts, and heavy metals like lead, arsenic, chromium and many other contaminants that pose potential health effects.

Stage 4/5 is a combination of an artesian remineralization medium and a 5-micron coconut shell granular activated carbon post-filter. Here the RO water is further polished by removing any residual chlorine, VOCs and other chemicals.

The refined RO water is then enhanced by the remineralization medium in the same stage. The medium consists of crushed marbles that restore natural calcium and magnesium minerals to the refined RO water thereby raising its alkalinity level before it’s delivered into the holding tank for storage.

From the RO tank, the water goes through a 6th/7th stage where one last filtration and enhancement is done by the carbon post-filter and the artesian remineralization medium.

This last stage clears out any remaining odor and tastes from the RO tank while giving the water one more small addition of calcium and magnesium minerals before it’s delivered to the faucet.

Full Contact Technology

As I mentioned above, the last four stages of the TMAFC are made possible by Home Master’s patented Full Contact Technology. It’s the top feature that sets apart all of Home Master’s RO systems under its full contact series.

This technology allows the system to circulate the purified water through the artesian and carbon filter twice. Once when moving to the RO tank, and once again when moving from the RO tank to the faucet.

This process of remineralizing the water twice is what makes this TMAFC model and the other Home Master full contact systems more robust compared to most of its competitors.

It restores enough minerals to produce clean, pure water with much better-balanced pH levels of around 7.5 to 8.0. In other words, it will certainly give you a cleaner, mineral-rich drinking water that has a fresh natural taste.  

Moreover, the full contact remineralization technology helps prevent the degradation of the RO storage tank.

The filtered water from the RO membrane is usually slightly acidic and when it sits in the storage tank, it attacks the rubber bladder and even dissolves some of it. This degradation often ends up affecting the taste of the water.

Therefore, the inclusion of the remineralization stage between the RO membrane and the tank is a big plus that not only reduces the acidity of the water but also helps prevent the degradation of RO tank and prolongs its lifespan.

Filtration Capacity

The Home Master TMAFC can deliver up to 50 gallons of pure water a day, so it’s much ideal for small or medium-sized households.

The downside though is that the system is not that efficient as the wastewater produced is a little above the usual standard.

Like the Home Master TM model, the unit generates 4 gallons of wastewater for each gallon of clean water produced. This ratio may, however, vary based on the pressure of the source water. The higher it is, the less water wasted.

Installation and Maintenance

When it comes to installation, the TMAFC won’t give you much trouble as it’s tailored for easy DIY installation. Everything you need to set it up is provided including the installation instructions an installation videos are also available to make the process easier.

Same as all the other Home Master RO systems, the filters media and their housings come in one modular assembly hence filter changes are quick and painless. No wrenches required.

The replacement of stage 1, 2 and 4 filters happens once a year while the membrane requires changing after 3 to 4 years.

Generally, despite the high wastewater rate, this Home Master TMAFC model is a great water filtration system that’s worth every penny.

It’s a solid investment especially for anyone looking for a unit that can provide safe, clean water with balanced alkalinity and a pleasant fresh natural taste.

What is the maintenance cost for this RO system?

It depends on your water usage and water conditions, the annual filters changing cost about 80$, the RO membrane replacement is about 56$ (last fo 3-5 years.

Are the components BPA free?

Yes, the system with all the components are BPA free

What is the size of the hole for the faucet?

It’s about 1/2″.

Can I add a permeate pump to this RO system?

Yes, you can. But you better use the booster kit from this brand to make sure the system works properly, be aware that the warranty may not valid if the RO system gets any problem from the integration.
