#3. Home Master TMAFC Artesian

Summary 

• Contaminants removed: chloramines, chlorine, chemicals, heavy metals, dissolved solids, pharmaceuticals and more
• Filter life – 2500 gallons or 1-year
• Replacement filter – Tap Master ISetTMA8 Artesian And HydroGardener Replacement Water Filter Change Set
• Filter Stages-7 stages 

The home master reverse osmosis filter system uses innovative design to solve the most common problem found in traditional RO systems. Some of the issues it addresses are the following:

• Slow flow rate –

Tradition RO system has a slow water flow rate but the home master system flow rate is twice faster than the traditional RO system.

• Canister filter housing leaks-

Traditional RO system canister filter housing is designed where only the filters are changed and not whole housing.

 With time sediment, microorganism and other contaminants can accumulate in the housing causing it to leak and fail.

The home master system uses modular all in one design where the filter is incorporated with the housing. during the filter change time, both filters and housing are disposed of.

The annual change reduces contaminants build up in the housing and therefore eliminates leaks.

• Slightly acidic water

The traditional RO system produces demineralized water that is slightly acidic.

When acidic water stays in the storage tank the acid attack the rubber bladder and dissolves some of it. This is known as tank degradation and also affect the taste of water.

The home master system has two points of remineralization stages which add minerals in your water making the water alkaline. therefore no tank degradation and produce water with great taste.

This system filters water in seven stages which remove chloramines, chlorine, chemicals, heavy metals, dissolved solids, pharmaceuticals, and other contaminants. 

The system 7-stages include: 

Stage 1: (1) 5 micron spun poly

Stage 2: high holding depth sediment water filter

Stage 3: coconut shell granular activated carbon water filter.

Stage 4: catalytic carbon

Advance carbon media are known as catalytic carbon which is better than ordinary carbon pre-filter making it effectively remove stubborn chemical disinfectants like chloramines.

Stage: 2 remineralization

The system has two different points of the remineralization process. One occurs when water travels to the storage tank and the other one when the water travel to the faucet.

At both points of remineralization calcium and magnesium minerals are added for great taste.

Remineralization help prevents storage tank from degradation and helps increase PH level making your water alkalinity.

The home master system filter is easy to change and are changed only once in a year or after every 2000 gallons. You can buy replacement filter using the link below

Tap Master ISetTMA8 Artesian And HydroGardener Replacement Water Filter Change Set
