pH Regenerate

Best Countertop Water Filter

Invigorated Water has been in the water treatment market targeting on the alkaline water filter. Here are some of the key features for the pH Regenerate filter.

Multi-Stage Filtration With Alkaline Remineralization: This system has two filtration cylinders which capable of removing contaminants plus naturally adding in minerals that raises the pH level. Contaminants that were removed include heavy metals like lead, arsenic, copper & mercury as well as common city water contaminants such as chlorine, chloramine & limescale.

By adding zinc, magnesium & selenium, it improves the water taste, pH and decreases -ORP.

Stainless Steel Housing: Unlike other systems, it comes with a stainless steel housing which is more durable and can handle higher water pressure. It is more stylish and it can easily blend into any kitchen designs.

Long Lifespan & Maintenance: The pH Regenerate is build to last. The filter cartridge, PH007 can last up to 12 months before you need a replacement.

Annual Maintenance Cost: $50

Bottomline: The pH Regenerate combines filtration and remineralization in one compact housing. It is definitely our No.1 Recommended countertop water filter.


+ Multi stage filter with remineralization filter
+ Durable stainless steel housing.
+ Long lifespan and low maintenance cost.
+ Easy installation


Not suitable for well water.


Best Reverse Osmosis Countertop Water Filter

APEC RO-CTOP is one of the few over the counter filtration system with reverse osmosis capability.

Below are the three reasons why this is our top-rated countertop filter.

High Flow Rate Filter:  Traditionally reverse osmosis filter comes with a bulk storage tank due to the flow rate is low. In order to remove the storage tank, APEC increases the flow rate of RO-CTOP to 90 gallons per day.

The flow rate capacity only appears in the top tier products which are priced close to $300. The APEC RO-CTOP is really a good bargain.

Reverse Osmosis Filtration: APEC claimed that the RO-CTOP is capable of removing 99% of harmful contaminants and provide an excellent filtered water quality.

APEC RO-CTOP Contaminant Removal

It is 4 stages reverse osmosis water filter which contains a sediment filter, a pre-carbon filter, a reverse osmosis membrane, and a post-carbon filter.

Quick Installation And Replacement: The APEC RO-CTOP doesn’t require complicated installation like other reverse osmosis filters. Just screw on the faucet adaptor and you are good to go.

Unlike other water filters, the APEC RO-CTOP required no wrench for replacement. It comes with a Quick Connect capability by inserting or releasing the tubing for replacement.

Annual Maintenance Cost: $70

Bottomline: The APEC RO-CTOP combines the benefits of reverse osmosis and the portability of countertop water filter.

Expensive Initial Investment

Berkey Filter

Best Gravity Fed Water Filter

Berkey is one of the top gravity-fed water filters that are available in the market. Sadly that it is not available in Iowa and California due to the banned imposed by the two states.

After a thorough understanding of the situation, we think that the banned is due to some regulatory request by the state which was unable to fulfill by Berkey due to hefty cost.

We believe that it is still a great piece of water filter which shouldn’t be missed. Let’s dive deep into the Berkey system and understand why we think that it is that great.

Great Quality Filter:The foundation of Berkey systems is made up of two separate cartridges, the Black Berkey and the Fluoride Filter.

Black Berkey and Fluoride Filter

Black Berkey: It is a microporous filter, which removes up to 99.9% on some of the contaminants that appear in the water.

It was independently tested in the EPA-approved laboratory against NSF/ANSI Standards 53 to ensure the quality of the filter is being achieved.

The Black Berkey is easily cleanable from time to time when the flow rate started to get low. This can prolong the lifespan of the cartridge.

Fluoride Filter: Although it is named as a fluoride filter, it can do better than just removing fluoride.

Besides fluoride, this system is able to remove Arsenic, which is one of the dangerous contaminants available in our water source. Apart from Arsenic, it removes MBTE and some other heavy metal ions.

The combination of Black Berkey and Fluoride Filter, Berkey is capable of filtering the list of top 20 major contaminations shown below.

Berkey Contamination List

For a more in-depth list of contamination that is filtered by Berkey, kindly refer to this list.

Besides the chemical contaminants, their filter also removes 100% of pathogenic bacteria. Generally, it is required to have a UV light sterilizer to remove the bacteria.

Variants And Sizes: There are different models of Berkey to cater to different needs. Take Berkey Go as an example, it is designed for hiking and traveling purposes with it’s small and compact size.

While the Crown Berkey is suitable for small offices or huge household as it container can store up to 6 gallons of water at a time.

Berkey Water Filter Models and Size

One of the best sellers is the Big Berkey, which is having an ideal size of 2.25 Gallons that is enough for a decent size family of 4.

Replacement Cost: A pair of Black Berkey can withstand up to 6000 Gallons of water as suggested by Berkey. This is mainly due to the cartridge is cleanable

The Fluoride Filter is small in size. Hence, the lifespan is just about 1000 Gallons per pair or approximately 2 years for one set of replacement.

Annual Replacement Cost: $80

Lifetime Warranty: When you register your Berkey, you will receive a Berkey Care Lifetime Warranty instead of the standard 6 months warranty. However, this only applies to Travel, Royal, Big, Imperial, and Crown Berkey.

Bottomline: It is great to see how Berkey can build such a simple filtration system while still capable of removing so many contaminants. Although the flow rate might be lower compared to the rest of the system, it is a great system that you will never regret.
