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.

iSpring RCC7AK RO System [Alkaline Remineralization]

The iSpring RCC7AK is an upgraded version of the RCC7 model with the addition of a nice extra filter. It can filter out all types of contaminants and enrich the water in the same process giving you a healthier, natural-tasting, clean drinking water.

Excellent Filtration Process

The RCC7AK features multi-layered filtration process designed around 6 very efficient filtration stages specially tailored to progressively remove all types of contaminants and improve the water quality.

The first three stages are pre-filters consisting of polypropylene sediment filter in the 1st stage, GAC filter in the 2nd stage and a carbon block filter in the 3rd stage.

These three filters trap all the sediments and particles that are larger than 5 microns and more importantly removes chlorine, chloramines and other chemicals present in the water.

The fourth stage where the magic happens sits a quality RO membrane which eliminates all the remaining contaminants down to 0.0001 microns leaving behind only pure water.

A fine GAC filter takes the fifth stage and where the water from the RO tank is further polished to remove any residual contaminants from the tank.

Restoration of Lost Minerals

After going through the initial 5-stage RO filtration process, the RCC7AK includes a 6th stage which consists of an alkaline remineralization filter.

The standard 5 stages produce clean, pure water with all the contaminants removed as well as the few helpful minerals present in the water.

This 6th stage is a big plus as the alkaline filter restores the healthy minerals lost due to the RO process. The AK filter features red mineral stones which add back calcium and other essential minerals such as magnesium and potassium.

The filter also has a calcite portion that helps raise the pH levels of the RO water hence creating a much natural alkaline balance in the water.

Therefore, you not only get the benefit of drinking clean, purified water but you are also assured of getting some healthy minerals as well and a better, more natural taste.

RO water is so pure and as such it often tastes unnatural, but with this alkaline filter in place, your water will certainly taste much better.

Furthermore, the filter is made up of only natural mineral stones that serve as the filtration media hence your body will have no problem absorbing the restored minerals directly.

Filtration Capacity

The filtration capacity of RO membrane of this iSpring RCC7AK model is also quite decent for an under-sink residential RO system.

It’s capable of producing up to 75 gallons of filtered water a day which is sufficient to handle the water needs of small to medium-sized families whether it’s drinking or cooking.

Moreover, the system is relatively efficient as for each gallon of pure water produced, it wastes only 2 gallons which is really a mean feat for most filtration systems.

Installation and Maintenance

Featuring quick fittings, a cabinet fitted bracket and a clear, well-organized manual and videos, installing the RCC7AK is quite easy, especially if you have some little DIY skills.

All the parts you need including the pressurized tank, faucet, drain saddle, feed water adapter, tank valve and tubings are provided alongside the filters, membrane and the RO frame itself.

The system will easily fit under any standard kitchen sink and the overall construction is quite solid. The filters are durable too with the first three pre-filters requiring replacing just twice a year and the two post-filters requiring changing once a year.

The membrane will last 2 to 3 years based on the quality of your source water. Noise won’t also be a major problem like in other systems. The unit runs smoothly producing the least sound possible. 

All in all, the iSpring RCC7AK is a well-designed RO system with an effective 6-stage filtration process that eliminates all kinds of contaminants from the water and replenishes it with essential, natural minerals.

It’s definitely a win-win investment for anyone looking for an affordable system that can deliver a more natural tasting and healthier filtered water.


  • Efficient filtration process ensures crisp, clean, drinking water
  • Restores healthy minerals to the water and improves its pH balance
  • Decent filtration capacity and pure to wastewater ratio
  • Durable stainless steel construction 
  • Easy installation with a convenient noise-free operation

iSpring RCC7AK-UV 7-Stage Reverse Osmosis System

The iSpring RCC7AK-UV is yet another top-notch model within the iSpring RCC7 series. It’s the variation of the iSpring RCC7AK model offering the same great RO system that features a remineralization filter but with the addition of a UV light filter. 

iSpring RCC7AK-UV is a deluxe multi-layered reverse osmosis system that provides optimal protection against more than 1,000 different types of contaminants including arsenic, asbestos, chlorine, hormones, fluoride, lead, mercury, sodium, bacteria, giardia, viruses and more.

The RO system consists of 7 processing stages, the first 6 stages work similarly to the previous system RCC7AK, the 7th stage is an 11W UV bulb as an additional protection layer that against the variety of microorganism that past the RO filter.

Filtration Process

The RCC7AK-UV comes equipped with 7 filtration stages which makes it one of the most comprehensive RO systems from iSpring and one that guarantees the best water quality possible.

The initial 5 stages consist of the standard iSpring’s 3 pre-filters we’ve seen in the other models and they remove all large contaminants down to 5 microns and chemicals particularly chlorine and chloramines.

They are followed by the 0.0001-micron RO membrane that removes up to 99% of all the remaining contaminants. The fifth stage is a finer GAC filter which gives the RO water the final polishing as it leaves the RO tank.

After passing through these initial 5 stages, the RCC7AK-UV model incorporates two more stages comprising of an alkaline remineralization filter and a UV sterilization filter.

Sixth Stage – Alkaline Filter

The 6th stage of the RCC7AK-UV uses an alkaline remineralization filter which is made up of red mineral stones that restore the healthy minerals removed from the RO water by the initial 5 stages. It adds back calcium, magnesium, potassium, and sodium.

The filter also has a calcite portion which helps raise the pH level of the RO water to natural alkaline balance giving a better and more natural taste. This is essential as the RO filtration process reduces the pH value of the water making it tastes slightly acidic.

Seventh Stage – UV Sterilization Filter

The final stage in this RCC7AK-UV system features a UV sterilization filter that offers an additional level of protection from possible microorganism contamination.

The filter uses a powerful 11W UV lamp which emits UV light as the water passes through it. The UV light kills 99.99% of harmful organic microorganisms that might seep past the RO filters including bacteria, protozoan cysts and viruses.

To ensure great efficiency, the unit comes with a smart flow sensor switch too which turns off the UV light once the water is not flowing through it thereby saving power. The UV lamp also comes in a protective stainless steel housing to ensure its durability.

Filtration Capacity

The RO membrane of the RCC7AK-UV can deliver a maximum of 75 gallons per day. The capacity might vary though based on your source water pressure and temperature but it’s able to meet the needs of most small to medium-sized families.

The system, however, wastes around 3 gallons of water for every one gallon of clean water it produces. Considering that most of the other iSpring’s model has an average ratio of 2:1, this one will slightly waste more water unless you install a booster pump alongside it.

Installation and Maintenance

As with the other iSpring models in our list, the RCC7AK is not that hard to install yourself if you have basic DIY skills. Everything you need to set it up is provided and the instruction manual is user-friendly with pictures and illustrations that make it easier to understand and follow. The whole unit is compact and will nicely fit under any standard kitchen sink.

Overall, the quality, performance, and features of this RO system are really commendable. By combining both the alkaline and the UV lamp filter means you are always assured of clean, healthy water that has a much better and natural taste throughout.

It’s a system we would highly recommend for anyone wanting a unit that offers more than just the standard RO filtration process.
