U.nder sink water filters are great way to filter all the water that comes through your faucet.

WaterDrop RO WhiteThis means you will literally be able to drink the water from your kitchen tap and it will be clean and taste delicious.

If this is of interest then you’re at the right place because this article will go in-depth.

I’ll explain why under sink water filters are the way forward for most people.

I will also review one of the best under sink water filters available today;the home master HydroPerfection under sink reverse osmosis system.

This won’t be a love-fest though. I will point out all the flaws with this method of filtration and issues you should note before you buy.

Why Should You Get An Under Sink Filter?

Getting filtered water today is so easy. In fact, I would argue that it’s almost too easy because there are so many options. Each method with their own benefits and flaws. For instance, if you want a quick, easy and portable solution then you should get a water filter jug or water filter bottle. Need something heavy duty? Never want to worry about filtering water in your home again? Then try a whole house filter or an alkaline machine that also filters water from source.OptimH2O Reverse Osmosis Under Sink Filters

Getting an under-sink filter is somewhere in-between. It ensures you get clean filtered water at source but only from the tap faucet that it’s connected to. This means that other ater sources in your home e.g. shower, toilet etc. won’t have access to that filtered water.e pesticides, bacteria, heavy metals and chemicals like chlorine.

Getting an under-sink water filter is WRONG for you if:

  • You need the valuable storage space under your sink. The under sink water filter will take space under your sink. This makes it a bad choice if you live in a small apartment and desperately need all the space you’ve got including under your kitchen sink.WaterDrop RO Black
  • Getting a plumber is not an option and you want a quick easy, self install solution. Unless you have considerable plumbing skills you may need to get an expert to install your under sink water filter for you. However, note that once the filter is plumbed in, replacing the filter is very easy. In most cases replacing an under sink water filter is as easy as twisting it on and off.
  • The water that comes from an under-sink filter is not going to be as cold as the water you get from your refrigerated pitcher. Or the filtered water that comes from a refrigerator’s dispenser. But a quick fix for this are filtered water ice cubes!

Getting an under-sink water filter is RIGHT for you if:

  • You want permanent access to filtered water from a single water source e.g. your kitchen sink instead of paying for a whole house filter.
  • Don’t want to waste money filtering water for your bathroom, laundry and toilet with a whole house filter.
  • Believe that a water filter jug is too much work because its filters need replacing more often or some other reason.
  • Need access to a powerful filter that removes organic compounds. For instance, compounds like pesticides, bacteria, heavy metals and chemicals like chlorine.

Buying Guide For Under Sink Water Filters

Convenience: Your filtered water is delivered instantly. All you need to do is turn on the faucet and nothing but clean filtered water comes out. This is in contrast to a water filter pitcher, which usually takes a few minutes to filter water.

OptimH2O Reverse OsmosisThat doesn’t even include the amount of time it takes to open the fridge, fill up the filter pitcher at the tap and take it back to the fridge.

Capacity and speed: The best quality under sink filters (like the one reviewed below) cleans around 1,000 gallons of water. This means that some under sink filters can last for a year before they need to be replaced.

On the other hand, a standard water filter pitcher usually filters around 40 gallons of water before the filters need to be replaced. The result is the filters’ probably need to be replaced every couple of weeks.

Functionality: The filtered water that comes from an under sink water filter is so easy to use and anyone (even a child) can do it. Why? Because it is as easy as opening a tap faucet.

The Best Under Sink Water Filter

Even the most health conscious individual is likely to be very impressed with the Home Master HydroPerfection undersink reverse osmosis system.

Red CrossOne Slight Issue To Note.

The Home Master TMHP HydroPerfection undersink reverse osmosis water filter system has one issue that you should be aware about before you buy. It creates a tremendous waste of water. To be precise, the machine wastes 1 gallon for every 1 gallon it produces.

Green Plus ArrowBest Features and Specifications.

  • Very easy to change and replace its filters.
  • Filter your water with the power of UV light.
  • The filters are both long lasting and easy to change. You can expect them to last for around 2000 gallons or 1 year depending on your use.

  • The Home Master HydroPerfection has an innovative design that addresses some of the most common problems found with many traditional RO systems.

  • The result of this is you get highly pure water. Apart from the RO system that restores healthy minerals, this unit also filters out at least 98% of iron, heavy metals, chemicals, sediments and other types of contaminants you can find in water.

Final Thought On The Home Master HydroPerfection Under Sink Water Filters

Mr Water Geek ThinkingI like the Aqusana Undersink Reverse Osmosis because it uses multiple stages of filtration and purification to provide you with exceptionally clean water.

These multiple stages include the removal of iron, sediments, chlorine, pharmaceuticals, chloramines, hydrogen sulfide, metals, dissolved solids, chemicals and many other harmful contaminates.mrwatergeek winner badge

As if this isn’t enough, this unit also includes an advanced ultraviolet light sterilization mechanism. OptimH2O Reverse Osmosis Under Sink Filters

The guarantee is that it can safely destroy 99.99% of bacteria, germs, viruses and other dangerous microorganisms.

The only drawback that I can see is it’s wastefulness. 1 gallon of waste water is for every gallon of clean water. This is a heavy environmental price to pay.

But this is offset by the fact that you won’t use lots of plastic bottles. Or need to replace your water filter every 4-8 weeks as you would with a filter pitcher.
