What’s the Best Under Sink Water Filter? Here are my Top 7!

Under sink water filters have gained popularity as a preferred and easy water treatment option for homeowners. Generally, H2O in most homes in the United States is suitable for showers and laundry, but some question whether it’s truly safe for drinking. Therefore, under sink water filtration has become commonplace because it provides homeowners with a long-lasting and effortless purification system. It eliminates harmful chemicals, leaving minerals that our bodies require to stay healthy.

With an easy installation process and filter changes, an under sink water filter is easy to use and maintain. The filtration procedure is also much quicker and leaves your water clean, with a natural taste and odor. The filters are also completely hidden from view, so homeowners don’t have to worry about needing extra space to add a filtration device. Because of the multiple benefits of the under sink water filters, they have been a great alternative to traditional RO (Reverse Osmosis) systems. 

In addition to being practical, tidy, easy to use, and super-fast, under sink water filters are also friendly to your pocket. The removable filter cartridges used to filter the supply last for up to 6 months until needing replacement. This treatment option can provide you up to 6800 liters of clean, fresh, and natural H2O straight from the faucet – you will never need bottled water again! 

Why Use a Faucet Water Filter?

Here are the benefits of using under sink water filters:

Improve the taste

Depending on the city you live in, your tap water might have an unpleasant taste or smell. This is probably because of the small dosage of fluoride or chlorine that are often present in tap water. Many people in large cities experience an off taste to their faucet supply, or even unpleasant odor. This sometimes causes people to avoid drinking water as much as they should, or opt for bottled. Adding an under-sink water filter can solve this problem. 

Make water safe for drinking

It’s not just the taste and odor that improve when you install under sink water filters. These devices also remove unsafe chemicals, impurities, and particles that may be present in your tap water. The filters aren’t just for aesthetics, but also for safety. 

Add mineral supplements

A good under-sink water filter can actually add healthy minerals that significantly improve your drinking water quality. 

Improve the physical development of your kids

In a household with growing kids, it is essential to have a high-quality drinking water supply. Drinking unhealthy water can cause your kids to develop unnecessary deficiencies and stifle their development. 

Additionally, tastelessness of water can cause your kids to develop the unhealthy habit of drinking less water than their bodies require. Installing an under-sink water filter will ensure your whole house is supplied with tasty and healthy H2O.

No need for extra space

If you’re looking to capitalize on the small space in your kitchen, an under-sink water filter can be a great option. This sink water filtration system doesn’t take up extra space like the counter water filter. The space under sinks is perfect for storing the device out of sight, compared to the counter water filter. This utilization of extra space makes an undersink water filter the preferred choice to provide a clean water supply for the whole house. 

Fairly easy to install

Installing your under sink water filter only requires minimal plumbing skills. Thanks to the multiple resources on the internet, you can find DIY installation guides for the sink filter. Most of the DIY installation guidelines are clear and easy to follow, which allows for simple and quick installation. 

Although the installation process might be more complicated than installing a counter water filter, you don’t need tons of plumbing experience to get the job done. 

Cost-efficiency

The cost-efficiency of under-sink water filters is second to none. They are much cheaper compared to other options such as reverse osmosis systems. They also save you lots of money that you would have used to purchase bottled H2O. 

Under sink water filters are also more efficient than other types of faucet filters such as freezer filters. However, the efficiency depends on the brand you purchase. Regardless, the cost of purchasing a sink filter is quickly compensated by its benefits. 

Variety of models

There are two main types of under-sink water filters, but there are many models you available in the market. Your choice depends on the brand you prefer. There are under-sink water filters that not only filter H2O but also enrich it with minerals. Some only have one filter while others have multiple filters. 

Conventional systems generally have multiple models to choose from, but simple under sink water filters are popular too. The variety of options allows homeowners to choose the sink filter that fits their budget and requirements.

Easy to maintain

Under-sink water filters don’t need complex maintenance to keep them functioning properly. You only need to replace the filter twice a year. Replacement of the sink filter is similar to that of counter water filter, but you’ll have to get on your knees to change the cartridge under the sink. 

Now that you are aware of the benefits of under-sink water filters, let’s discuss the best models that you can purchase today.

#3 Home Master TMHP HydroPerfection

The Home Master TMHP HydroPerfection is one of the best reverse osmosis systems used at home because of its multiple benefits. It can be applied in any home, whether you source your H2O from the municipal services or a well. 

The system is efficient due to its 9-stage filtration procedure, which effectively removes impurities, odors, contaminants, organisms, and total dissolved solids.

This filtration system produces 75 gallons per day, from feed water of about 76 gallons. This means that the Home Master TMHP HydroPerfection only wastes a single gallon. 

The filtration system also comes with a permeate pump, which plays a key role in ensuring there is minimized wastage. This Home Master TMHP HydroPerfection filter eliminates bland taste because it remineralizes all the beneficial minerals into the water to improve the taste. The filter also raises the pH to be more alkaline. 

Another reason this system is effective in improving the taste and quality of filtered water is the integration of UV light into the filtration procedure. What you’ll be drinking from the system is pure and fresh tasting because 99.8% of microorganisms will be removed.

The filter system is easy to install, and even people with little plumbing experience can do it within an hour. You only need to understand the process by reading the manual or watching online videos. 

Features

  • Design – the Home Master TMHP HydroPerfection filter integrates the modular under-sink water filter design to prevent severe damage. In most conventional RO systems, users only replace the filters while housing remains the same. This allows the organisms to remain in the container. The accumulation of organisms can make the container weaker, resulting in leakages. In the end, it causes serious damage, which can cost a lot. In modular under-sink filter design, filters are incorporated within the housing. This makes it possible for the housing to be replaced along with the filters. Organisms don’t get the chance to destroy the system. What’s best about the modular filter design is that replacing the filters is as easy as pushing out the old one and pushing in the new one. 
  • UV filtration system – traditional reverse osmosis systems are fairly effective in filtering the water, although the microorganisms remain most of the time. Using chlorine becomes the only way to deal with these microorganisms, but it is not that much effective. The Home Master Hydroperfection uses UV light to kill these microorganisms from the feed water. The process results in the removal of 99.8% of microorganisms from the filtered water. This process is approved by the EPA. The standard 110V power outlet is required for UV Light. This ensures you always drink fresh tasting purified water.
  • Reduced wastage – Most of the reverse osmosis systems waste a lot of water during purification. The level of wastage depends on the feed water pressure, which means the more pressure you have, the less H2O will be wasted. Thanks to the permeate pump in the Home Master TMHP, wastage is reduced by a great margin. The one-gallon wasted a day is useful in cleaning the membrane so that it keeps producing purified water. 
  • Flow rate the Home Master TMHP has a faster flow rate compared to traditional RO systems. The permeate pump increases feed water pressure, which in turn increases the flow rate to your sink.
  • Remineralization – The remineralization stage is essential in adding valued minerals, thereby improving the taste.
  • Warranty – The manufacturer offers a 6-year warranty for the product, making the Home Master TMHP a secure investment for your home.
