Home Master TMULTRA Reverse Osmosis System Review

The Home Master Ultra series consists of refined and more advanced models compared to those in the standard and full contact series. The company has three models under its Ultra series which include the TMULTRA, TMULTRA-ERP, and TMULTRA-ERP-L.

All three models come equipped with iron pre-filter and UV light post-filter which are not available on both Home Master’s basic and full contact systems. However, these models differ slightly in terms of additional features.

The TMULTRA is the standard system in the series while the TMULTRA-ERP is also similar to the TMULTRA model but has a permeate pump.

The TMULTRA-ERP-L, on the other hand, is the loaded version which in addition to having a permeate pump, it features an RO membrane which offers a higher production rate than both the TMULTRA and TMULTRA-ERP models.

In this review, we look at the standard version of the series, the Home Master TMULTRA and we will highlight how it compares in terms of performance and efficiency to the other two models.

Filtration Process

The Home Master TMULTRA is integrated with 6 stages of filtration similar to both the TMULTRA-ERP and TMULTRA-ERP-L models with the two outstanding filters being the iron pre-filter and UV light post-filter.

The system is designed to perform filtration, purification, and sterilization through the six stages generating exceptional clean and fresh drinking water

The 1st stage is fitted with a sediment filter which removes all the sediments and particles down to 5 microns.

The 2nd stage of the system is the powerful iron pre-filter which is one of the key features in all of Home Master’s ULTRA RO models. The filter is a combination of KDF85 media and catalytic carbon media.

The KDF85 media clears out manganese, hydrogen sulfide and iron from the water which would otherwise destroy the membrane.

If you have a private well at home and it contains iron, this is in an ideal system for it. The type of iron often found in well water can completely destroy the RO membrane without the iron pre-filter protecting it.

Traditional reverse osmosis systems are usually destroyed easily when filtering well water but the advanced redox KDF85 media in the iron pre-filter will effectively remove iron from the water and protect the membrane.

Additionally, the catalytic carbon media in the filter helps remove chlorine, chloramines and other chemicals like herbicides and pesticides from the water which are often responsible for the unpleasant cloudiness, taste and odor.

The Dow Filmtec RO membrane makes up the 4th stage of the unit and it strips the water of all contaminants that are larger than 0.0001 micron which basically eliminates 98% of dissolved solids like fluoride, nitrates; heavy metals like lead and arsenic; bacteria, viruses and residual chemical contaminants such as chlorine and chloramines.

The 5th stage consists of a post-carbon filter that removes any odor or taste from the RO storage tank as the water moves to the final stage which is the UV light filtration.

Stage 6: UV Light Filter

The inclusion of a UV light filter is one of the reasons that makes the Home Master TMULTRA as well as the TMULTRA-ERP and TMULTRA-ERP-L models ideal for filtering well water and even regular municipal water.

The UV light filter is very effective at destroying microorganisms without changing the water’s chemistry or adding harmful chemicals.

After the water leaves the post-carbon filter, it’s channeled through the UV light sterilization chamber where it’s bombarded with an intense UV light wave (254 um).

The light penetrates the cells of the living microorganisms in the water, distorting and destroying their DNA and RNA thereby leaving them effectively neutralized.

The filter can get rid of up to 99.99% of all the microorganisms present in the water including viruses, bacteria, and more than 60 different germs and other microorganisms. This results in exceptionally pure water that’s free from contaminants. 

Filtration Capacity and Efficiency

With regards to filtration capacity, the TMULTRA can produce a maximum of 50 gallons of clean water daily which is an average rate that’s good for small households.

The system has a water efficiency ratio of 4:1, it wastes 4 gallons of water for every gallon of pure water generated. Therefore, it’s certainly not efficient.

If you want better system efficiency, a good option would be the TMULTRA-ERP model which includes a permeate pump that helps cut down water wastage by 80% to a ratio of 1:1 and as well boosts the production rate by up to 50%.

If you are after more capacity, then the TMULTRA-ERP-L is the ideal choice as it comes with a 75GPD high capacity membrane and a permeate pump which boosts the production capacity up to 100 gallons of purified water a day.

Installation and Maintenance

The installation process of the TMULTRA is quite easy and straightforward because all the filters and tubing come pre-installed in one cluster RO system which you just push in into the mount on the cabinet wall.

The whole system can be set up in under an hour. The other two models, the TMULTRA-ERP and TMULTRA-ERP-L are equally easy to set up too with the only additional part being the permeate pump.

As for maintenance, you will have little to do as the filter are durable and easy to change due to their modular design.

All the filters including the UV bulb can go for up to one year before requiring replacing while changing the RO membrane is recommended every 3 to 5 years.

The system will need electricity to power the UV light which is the only thing that’s likely to a pose a challenge because you will need to set up power supply (110v) in case you already don’t have one inside the cabinet area. 

In general, if you get your water from a well, the Home Master TMULTRA would be great for you. You can also go with the Home Master TMULTRA-ERP or the TMULTRA-ERP-L if you want high efficiency and production rate.

What is the difference between the TMULTRA vs. TMAFC RO systems from Home Master?

The TMULTRA has iron pre-filter and UV post-filter that are not available on the TMAFC while the TMAFC supports the Artesian filter with full contact technology and re-mineral post-filter.

Do the pump and the uv light have separate plugs?

No, there is only one plug spare for both the booster pump and the UV filter.
