Home Master Reverse Osmosis Water Filtration Systems

The first three reverse osmosis systems on our list are made by Home Master. The company is one of the leading sellers of reverse osmosis filters and one of our favorite brands. They offer an impressive 5-year manufacturer warranty.

The Home Master brand, (formerly known as Tap Master) is owned by Perfect Water Technologies. The company was founded in 2002 and manufactures several types of household water purification systems. They currently have an A+ rating on the Better Business Bureau.

Perfect Water’s product line includes reverse osmosis systems, whole house water filters, faucets and shower filters. We reviewed three of their reverse osmosis water filters that include mineralized water on tap.

1. Home Master TMAFC Artesian Full Contact Undersink Reverse Osmosis Water Filter System

The Tap Master Artesian Full Contact System (TMAFC) uses a seven stage filtration process. This RO filter removes up 99% of heavy metals, chlorine, fluoride, dissolved solids, and other contaminants.

What makes the TMAFC model different is the design of the filter system. Instead of using a canister, each filter is self-contained within a filter housing. This helps to reduce leaks and build-up on the housing. Instead of just replacing the filter, the entire filter housing is replaced. Plus, the filters last a long time, requiring replacement after 2,000 gallons or about 1 year.

The Home Master RO system uses a full contact natural mineralization system to balance the water’s pH. This occurs in two separate stages – once when the water goes into the tank. Then a second time just before it is dispensed into the faucet. The result is a slightly alkaline and clean tasting water.

2. Home Master TMAFC-ERP Artesian Full Contact Undersink Reverse Osmosis Water Filter

The Home Master TMAFC-ERP is one of our favorite units. Included in the system are all the same great features of the base unit: an easy to change, modular filter design, seven stages of filtration including two remineralization points, and DIY installation instructions.

In addition, The TMAFC-ERP includes a built-in pump system that reduces wastewater by 4 times of the original design and increases output to 75 gallons per day. This improves the efficiency of your system and also increases the flow rate when compared to similar systems.

If you take a look at our larger comparison chart here – you’ll see that almost all the other units have double or triple the amount of wastewater. This was a pretty big selling feature.

The improved flow rate, better wastewater ratio, and natural alkalinizing process make this our favorite reverse osmosis home system of the year. Plus you get the 5- year manufacturer’s warranty from the company.

3. Home Master TMHP HydroPerfection Undersink Reverse Osmosis Water Filter

Home Master TMHP HydroPerfection has nine total stages of filtration. The water is processed through the same 7 stages as the previous model to remove 98% of contaminants and adding back the beneficial minerals to produce alkaline water. In addition, there is an added: a UV light and an Iron prefilter.

The Ultraviolet light filter is used to protect against microorganisms, viruses, and bacteria that may be lurking in the water. UV light is recognized by the EPA as a safe way to sterilize water without adding any additional chemicals. Also included is an additional Iron prefilter that protects the reverse osmosis membrane from the type of dissolved iron found in many well water systems that could damage your unit.

While most city water sources may not require these two extra layers of protection, it can be useful for untreated water sources from river and lakes or homes with that use well water.

Find out all the facts on reverse osmosis home systems and decide whether you should purchase one for your home.

What Is Reverse Osmosis?

In the simplest terms possible, reverse osmosis, or RO, is a system that pushes water through a series of filters and membranes to remove impurities. There is a lot of history behind it and a more scientific way to explain the process, but to understand how it can make the water you consume cleaner and healthier, you can skip the history lesson and the geek-speak.

RO On A Grand Scale

Most municipal water systems use reverse osmosis to clean the H2O that flows out of your tap. Large water filtration systems like that usually use a cellulose triacetate filter (CTA) that requires the water flowing through it to be chlorinated to keep bacteria from building up on the filter.

A higher quality filter known as TCF does not need the water to be chlorinated to work and usually employs a carbon filter to absorb chlorine and keep the water tasting good.

Despite the fact that city water supplies are put through some reverse osmosis, the water that ends up in your faucet usually has some sediment, minerals, bacteria, chlorine and even viruses in it.

Reverse Osmosis Home Systems – Benefits and Cost

A reverse osmosis system for the home is an excellent way to produce very clean, pure, healthy water. Here is what a home RO system can do for your water and why they are a good investment:

• Removes impurities like salt, heavy metals, odors and other impurities from your drinking water
• They have a low energy consumption
• They are easy to maintain (filters last about a year)

For between $200 and $500 you can find a lot of different models. Buying on the higher end of that price range will ensure you get a better quality model. The main difference between the numerous systems to choose from is the quality of the filters and membranes. When you make your purchase, see if the unit has a warranty and for how long. Find out how easy it is to replace the filters and look for product certifications.

The National Sanitation Foundation (NFS)and Water Quality Association (WQA) are independent 3rd party certifiers of quality RO water systems. A good system should get:

• From NSF a standard of 58
• From WQA a Gold Seal Certification

Types of Reverse Osmosis Home Systems

There are a couple of options to choose from when deciding to purchase an RO unit for your castle.

1. Traditional Tank System

This is a unit that is installed under your sink and uses a series of filters that tap water is pushed through to clean it and then is stored in a tank. These types of systems have an additional faucet separate from your sink faucet to dispense the water. Be sure to get a model with an automatic shut-off valve so that it stops producing water when the tank is full instead of the water being wasted down the drain.

2. Tank-less System

These are relatively new to the marketplace. The advantages of having a tank-less system are:

• It is connected directly to the tap water faucet and dispenses water on demand
• There is less cabinet space needed because there is no storage tank
• This kind of system can dispense a large volume of purified water out of numerous faucets in the home

The disadvantage of a tank-less model are the higher cost of the unit, you have a lot more filters and membranes to replace, and it may require an additional purchase of a pressure booster pump to keep the water flowing.

The Stages of Reverse Osmosis

Here is how your unit will function and what each filter and membrane is for.

Phase 1 – water passes through a sediment filter to get rid of silt, dust and large particles

Phase 2 – GAC (granular activated carbon) filter removes chlorine, odors, mineral oil and bad tastes from the water

Phase 3 – A more dense carbon filter removes any remaining chlorine or bad odors or tastes that may still be lurking about

Phase 4 – this is the big one; reverse osmosis. The water is pushed through a very fine filter that can remove around 95% (or more) of the remaining impurities in the water like fluoride.

Phase 5 – a polishing carbon filter keeps the water in the tank from tasting stale while it sits in storage

Phase 6 – here is where you water gets alkalized, meaning the pH is adjusted to 7 or above using good minerals like calcium and magnesium.

Phase 7 – this final step employs a UV filter to kill any bacteria or viruses in the water

Now that you have an answer to how does reverse osmosis work, you can see the advantages of installing an RO home system. Fresh, clean, alkalized drinking water is more appealing to drink straight, use to make coffee or tea and include in our cooking.
