Got clean water?
Unfortunately, far too many people drink water tainted with at least a modest amount of dirt, sentiment, and/or harmful levels of chemicals. The answer to unclean and unhealthy drinking water is called an under sink water filter.
In this review, we analyze three under sink water filters offered by the highly-rated team at Puronics: Micromax 7000 Drinking Water System, Micromax 6500 Water Treatment System, and Micromax 6000 Drinking Water System.
As we are about to discover, the higher the Micromax brand number does not necessarily translate into a better under sink water filter.
What is a Reverse Osmosis System?
Puronics uses a scientific process called Reverse Osmosis (RO) to generate the highest drinking water quality. Our trademarked RO systems filter and soften your water for drinking, preparing food, and washing clothes. Our under sink water filter systems run water through a reverse osmosis membrane to remove harmful concentrations of minerals and other types of contaminants. RO systems take out harmful concentrations of minerals and replace harmful minerals with sodium or potassium to soften water. Carbon filters activated by a power source eliminate bad tasting and foul-smelling water.
Benefits of an Under Sink Water Filter
Under sink water filters have become a popular way to purify household water supplies. Let’s look at the many benefits a Puronics under sink water filter offers you and your family.
Safe and Healthy Source of Water
Many municipal water supplies contain harmful levels of chemicals and minerals. A Puronics drinking water system produces much healthier water by removing dangerous contaminants.
Ideal for Child Development
In households that have kids, an effective under sink water filter produces healthy water that in turn fosters positive child development. Unclean household drinking water inhibits the development of motor and cognitive skills.
Even small amounts of chlorine and fluoride can produce a bad taste in your household drinking water. Installing a Puronics under sink water filters removes bad-tasting chemicals such as fluoride and chlorine.
Unlike countertop water filters, each of the three Puronics under sink water filters takes up little storage space. This allows you to store the things you need to use for cleaning the kitchen in one convenient spot.
Relatively Easy to Install
Although it looks like installing an under sink water filter requires a Ph.D., the fact remains the water purification systems are relatively easy to install. You certainly don’t need the services of a licensed plumber to get your Puronics RO system up and running.
Cost-Efficient Way to Produce Clean Water
Under sink water filters are not only affordable, installing one designed and manufactured by Puronics will end the expensive habit of buying bottled water. You also benefit financially from using less energy to power the system.
Outside of kneeling to gain access to an under sink water filter, maintenance of it is easier than performing maintenance on a countertop water filter. You simply have to change the cartridge located under the sink, as well as clean the components to ensure maximum productivity.
Reverse osmosis is the process that produces the drinking water from the three Micromax under sink water filters that we have reviewed below. Not only do the three Micromax filters remove pathogens, contaminants, and harmful minerals, you can expect to notice a vast improvement in the quality of a glass of tap water, as well as the cleaner aroma wafting from a piping hot cup of coffee.
Based in Livermore, California, Puronics offers three high performance under sink water filters.
Micromax 7000 Drinking Water System
Enjoying clean and crystal clear water is just the start of a long list of popular attributes for the Micromax 7000 Drinking System. Other attributes are what separate the 7000 from competitors like GE and Apec.
The patented cartridges automatically shut down the water supply when it needs to be replaced. This ensures the constant delivery of healthy water for the entire family. The kitchen faucet adapter is ideal for users that like to micromanage every detail of an under sink water filter. Easy connection of the device eliminates the need to insert needle valves that typically require the services of a professional plumber. Four stages of filtering provide users with water that is free of chemicals, toxic rust, and harmful minerals.
The Micromax 7000 Drinking Water System fits underneath any size kitchen sink.
Best Features of the 7000
Operating on the water pressure generated in your home, the Micromax 7000 Water Drinking System does not use any electricity for running the filter. The slim, sleek design allows you to place more kitchen cleaning items under the sink. Without the need for needle valves, the filter connects to the cold water supply in a manner of seconds. Automatic water shut off allows for a quick and leak-free replacement of the filter.
Here several other features of the Micromax 7000:
- Sanitized water stores inside a tank that is tightly sealed
- Impurities in water flush down the drain
- Carbon filter activates to remove sediment that is a minute as 2/10,000 of one inch
- Because of the faucet adapter, there is not any need to call a professional plumber
- Strict water quality control and testing
- Customized long-neck faucet seamlessly blends in with any type of kitchen design
- Rugged valves and fittings deliver years of leak-free operation
- The filter acts as a barrier to prevent waterborne cysts from entering the home water supply
The most appealing feature of the Micromax is how efficient the filter is at removing unpleasant tastes and odors.
4 Stages of Water Purification
The first stage of operation for the Micromax 7000 involves the activation of the five-micron graded density carbon filter. Removing dirt, sediment, and rust particles that measure as small as 2/10,000 of one inch, the carbon filter spends time making contact with the filter media for dechlorinating home drinking water.
Stage two is when the water filter establishes protection against waterborne cysts such as giardia and cryptosporidium. The process is all about self-cleaning that removes waterborne cysts that measure just 1/10,000 of a micron. No other home water filter system removes cysts as small as the cysts removed from the Micromax 7000.=.
Reverse osmosis kicks in during stage three, when water molecules move slowly through the system. Stage three is when the system eliminates most of the dissolved solids like arsenic, sodium, and nitrates. The Micromax 7000 also removes dissolved metal particles from lead, copper, and chromium. All impurities automatically flush through the drain and then process water is sealed into a sanitized storage tank.
The last stage of the water filtering process eliminates the type of unpleasant tastes and odors that make home tap water undrinkable. Carbon of high-density cleanses the water in the storage tank to produce incredibly fresh-tasting and super-clean drinking water.
Micromax 6500 Water Treatment System
The Micromax 6500 Water Treatment System offers three of the same qualities that are offered by the 7000 model:
- Rugged durability
- Operational efficiency
- Certified by the EPA, NSF, and the Water Quality Association
Despite the numerous similarities in performance between the two Puronics under sink water filters, the Micromax 6500 water treatment system differs from the 7000 because it adds a fifth stage to the water filtering process. Do five stages make the Micromax 6500 the better under sink water filter?
Let’s find out.
Best Features of the 6500
While the Micromax 7000 Water Drinking System initiates the dechlorination absorption process during the first stage, the 6500 model uses two stages to get rid of harmful levels of chlorine. The 6500 also removes particles that are as small as 1/10,000 of a micron. To put that into proper perspective, a human hair measures between 10 and 100 microns in diameter.
In other words, the Micromax 6500 does not allow any particle to get through its five-stage water filtering system.
Here are other features that make the Micromax 6500 under sink water filer stand out:
- Operates using normal water pressure
- Does not require electricity
- Rugged materials deliver long-lasting durability
- Easy to change sanitary filter cartridges
- Never need to clean the smooth-running flow control system
- Beautiful chrome faucet comes with a long spout and lever that achieves two positions
5 Stages of Water Purification
With a filter graded at five microns, the first stage of the two-step carbon absorption process is to prevent dirt, rust, and sediment as minute as 2/10,000 or inch from entering the Micromax 6500 Water Treatment System. The second stage ensures the filter maintains extended contact with high-capacity porous carbon for the total absorption of chlorine.
Stage three introduces another filter that establishes a barrier to protect against dangerous waterborne cysts such as giardia and cryptosporidium. The self-cleaning process of stage three works the same way the self-cleaning process works in the second stage for the Micromax 7000 Drinking Water System. The cyst protection filer takes out particles that measure just 1/10,000 of a micron.
The fourth stage involves the FilmTec TFC membrane fostering the slow movement of water molecules while at the same time decreasing the level of dissolved metals and solids. This stage is also when the system removes radioactive materials like barium and radium. All the impure particles flush down a drain and store in a tank that is tightly sealed and thoroughly sanitized.
As the final stage for the Micromax 6500, water flows through a high-quality block to remove foul tastes and odors. The key to restoring water to a pleasant tasting condition is to reduce the level of volatile organic compounds (VOCs).
Micromax 6000 Drinking Water System
FDA and NSF compliant, the Micromax 6000 Drinking Water System comes with an automatic shut off system to conserve energy. You can produce up to 35 gallons of clean, healthy water every day. Minimal maintenance makes the 6000 perfect for less than skillful do it yourselfers. The slim design of the 6000 makes it the smallest under sink water filter offered by Puronics. If you have limited space beneath the sink, the Micromax 6000 might be your best option among the three Puronics models.
Best Features of the 6500
- Runs on household water pressure
- Does not require electricity
- Performance spec results included
- Advanced water flow control system never needs to be cleaned
- Rugged high-performance valves and fittings deliver years of leak-free filtering
- Sealed storage tank sanitized at the Puronics factory
Four Stages of Water Purification
Like the 7000 model, the Micromax 6000 goes through four stages of water filtering. Water passing slowly through the high-capacity carbon filter prevents dirt, sediment, and rust particles from contaminating your drinking water. A prolonged period of contact with the filter initiates the dechlorination process.
The ultrafiltration second stage takes care of illness-causing cysts by placing a filter that acts as a barrier. Particles as small as 1/10,000 of a micron cannot move through the filter. Reverse osmosis takes over during the third stage by eliminating dissolved solids such as arsenic, sodium, and selenium. The third stage also significantly reduces the concentration of heavy metals like lead and copper.
The fourth and final stage involves water moving through a high-quality carbon block to ensure the resulting drinking water possesses a pleasant taste and odor. With a reduction in VOCs, the comprehensive water treatment system produces clean, refreshing tap water.
The Bottom Line
When it comes down to deciding which of the three Puronics models to buy, you have to consider your unique drinking needs. For example, the Micromax 6000 produces water quality that is similar to the quality of water produced by the other two models. The advantage of the 6000 is the relatively small size of the system, which makes it ideal for homeowners that struggle with kitchen storage space. Comparing the 6000, the 6500, and the 7000 is like comparing a BMW to a Jaguar to a Maserati. With price points close together and the water quality about even, what differentiates the three under sink water filters? The answer is the second chlorination stage for the Micromax 6500. With an extra stage for dechlorination, the water that comes out of the 6500 achieves the ultimate in cleanliness. However, you cannot go wrong with any of the models, as the three Puronics under sink water filters run away with the award for best water f
