Water filters recently became prominent, especially over the last three or four years. Before now, American households do not consider an under-sink water
filtration system as an essential. Young people tend to buy packs of bottled water from the market, while the older people usually get water directly from faucets.
filtration system as an essential. Young people tend to buy packs of bottled water from the market, while the older people usually get water directly from faucets.
American citizens believe that their municipal tap water supply has been subjected to vigorous purification and sterilization procedures before it enters their homes.
However, this view is losing its support by the day, with so many scandals related to water safety being revealed. An example is the case of Flint water crisis, where the tap water source was found
to contain an amount of lead large enough to cause poisoning in small children in Michigan.

Although water has been well-treated before being sent out of the treatment plant, contaminants may find their ways into the water during transportation. Lead is one of
such contaminants; it is often found in old pipes where it can cause lead poisoning if accumulated over time.
such contaminants; it is often found in old pipes where it can cause lead poisoning if accumulated over time.
Therefore, it’s highly likely that water coming out from your home faucet contains lead, arsenic, and a bunch of other contaminants that can cause health problems in the short and, more often,
in the long term. Fortunately, with the discovery and evolution of filtration technology, we are better equipped to minimize the potential risks of contaminated water. There are now several filter options in the market to
choose from. That said, the most suitable type of water filters that meet the household water needs, including drinking and cooking, are under-sink water filter.

2. Home Master TMAFC-ERP Under Sink Water Filter – Best to Buy in 2021
This Home Master TMAFC-ERP Artesian under-sink water filter system is a top model in the filtration industry. Its efficient filtration, 1:1 low drain ratio, and long-lasting filters set the

standards for other filtration systems. The filter quality is backed by a made-in-US guarantee and NSF certificated components from Perfect Water Technologies, Inc.
A common talking point of RO water filters is the large amounts of waste water they produce, even more than the RO water. For a traditional RO water filter, the drain ratio can sometimes get
as high as 5:1, which means that it produces 1 cup of RO water for every 5 cups of waste water. However, the innovative point of this Home Master TMAFC-ERP is its powerful permeate pump, which greatly improves system
efficiency. It saves up to 80% of waste water, reducing the drain ratio to 1:1 – this is probably the lowest you can get among reverse osmosis systems. This pump uses energy from the rejected water, and thus doesn’t
even require electricity to work.

There are three inbuilt filters in the system – the spun poly sediment filter, the catalytic carbon filter, and the coconut shell granular activated carbon water filter. The efficient
filters bundle, alongside the RO membrane, reduces up to 99% of dissolved solids, chemicals, heavy metals, and more.
filters bundle, alongside the RO membrane, reduces up to 99% of dissolved solids, chemicals, heavy metals, and more.
Another special feature of this system is the catalytic carbon filtration media in the pre-filter. This material is especially effective in removing chloramine, a chemical used widely
as a disinfectant in the US. The Artesian remineralization also adds healthy minerals to the filtered water, especially calcium and magnesium, making it slightly more alkaline. This will show in your water TDS
reading, so don’t be surprised if the number is slightly high!

reading, so don’t be surprised if the number is slightly high!
The whole system is composed of an RO membrane, pre-filters to protect the RO membrane, a post-filter, remineralizer, and a water storage tank. All the required components for
installation comes with the system out of the box, including a drain saddle, fittings, tubing, and an adapter. It also includes a faucet; therefore, you can have purified water from a separate tap.

The system provides you with everything you need for pure alkaline water from your own kitchen. In traditional RO systems, the filter housing can be reused with a replacement filter,
posing risks of re-contamination. The Home Master TMAFC-ERP makes its filter and housing integrated into one single unit with the modular filter design. This makes it slightly more expensive, but better
hygienically and less susceptible to re-conatmination.

it a go-to water filtration system, in addition to its efficient filtration process.
Three outstanding features differentiates the Waterdrop undersink RO system from the competing RO systems.
First, unlike the traditional under-sink reverse osmosis water filter systems that rely on a storage tank to pump water out, the Waterdrop purifies water delivers instant water the moment you turn
on the faucet, even without a water storage tank. This helps avoid secondary contamination of the filtered water, often caused by growth of bacteria and viruses in the tank.
on the faucet, even without a water storage tank. This helps avoid secondary contamination of the filtered water, often caused by growth of bacteria and viruses in the tank.
Second, the system can produce up to 400 GPD (gallons per day) of purified water, while decreasing the drain ratio to 1:1, thanks to its in-built pump.
Third, the smart faucet has a LED ring on its stem, which will change into different color to indicate the status of the filtration system. When in use, the LED ring on the faucet shows various
colors to show you the status of the filtration system. Likewise, the frontal LCD panel on the filtration system shows both the filter status and the TDS (total dissolved solids) level of the filtered water in real time.
Other RO systems without TDS panels require a third-party TDS meter to check the water condition.
