Water Filter Comparison - Whole House Water Filter Vs. Drinking Water Filter

What’s the difference between a Whole House Water Filter and a Benchtop or Under Sink Drinking Water Filter?

As part of our commitment to water filter education this article is a comparison article, and today we are looking at the Whole House Water Filter and a Drinking Water Filter.

Whole House Water Filter

When we put the Whole House Water Filtration system beside a point of use water filter such as a drinking water filter, your question may be, “Do I really need to have both?”

Yes, you need both!

Consider a triple Whole House Water Filter like the one in the video above.

It’s got a sediment cartridge in position one, and a carbon cartridge in position two and three.

A Whole House Water Filter will process 20, 30 and even 40 litres a minute. I’m sure we can agree, that’s pretty fast. With the thickness of these cartridges and the water flowing at that speed, it can only remove specific contaminants, primarily chlorine

A Whole Home Filtration system will filter the water in your kitchen sink, the laundry, the showers, and even your hot water is treated. No more chlorine gas filling the air while you shower. A Whole House system really does a lot.

However, there’s a lot of pipework between the end of this water filter and your kitchen tap, and old homes can have lead connections, asbestos flashings and unknown contaminants lurking within the pipes.

So the best, and safest way to create the best drinking water you can is always going to be with a point-of-use water filter.

Drinking Water Filter

A point-of-use water filter is a filtration system that treats the water coming out of a single tap, like a kitchen faucet.

Now that can be a simple Benchtop Water Filter, Under Sink Water Filter, or even a Reverse Osmosis system would count.

Water Filter Flow Rates

Each water filter has a different flow rate.

Now, to remove the real nasties from the water, it comes down to the contact time with the media inside the cartridge, that’s the bottom line.

As you can see with the triple Whole House Water Filter, the water passes through 3 cartridges. 2 of those cartridges are super high quality carbon cartridges which go to town on all the chlorine in your town or city scheme water.

A Benchtop Gravity Water Filter treats about 1 litre per hour.

A Benchtop or Under Sink system generally works on about 2 to 4 litres of water per minute while a Reverse Osmosis system filters water at about 200ml per minute.

As you can see, the slowest is the Reverse Osmosis system - by far!

A Whole House Water Filter Treats Water 10 times Faster Than A Drinking Water Filter.

Now, to remove the real nasties from the water, it comes down to contact time with the media inside the cartridge.

What’s absolutely necessary for removing Fluoride is a much slower filtration rate. And that’s why we highly recommend using a point of use water filter such as a Benchtop, Under Sink Water Filter or Reverse Osmosis system to successfully remove the fluoride out of the water before it flows out of the faucet and into your glass.

Our Recommendation

If your highest priority is creating the best water you possibly can, you’ve got our guarantee.

We recommend a Whole House Water Filter of some description and then a point of use water filter such as a Drinking Water Filter system.

There is no better way to create the best water you can, outside of a Water Filter at your kitchen tap, immediately before it’s consumed.
