The easiest way to determine which system suits you is to identify the problem that you intend to solve. It isn’t that hard to pick a good drinking water filter for your home.

I will give my formula for choosing a great water filter with the following criteria below:

Filtration Quality:

  • How well in percentage does the filter remove contaminants?
  • Does it specify which contaminants that it removed?
  • What is the micron ratings that it can filter up to?
  • If it is a reverse osmosis system, what is the TDS rating after filtration?

Cartridge Replacement:

  • How long does the lifespan of each filtration cartridge?
  • The longer the lifespan of filters means that the better technology that was used on the cartridge.

Affordability:

  • Is this system within your budget?
  • What is the annual maintenance cost of the system across 5 years?

  • Most systems required drilling in order to secure the system under the sink. Does it require complicated installation that incurred additional installation cost?

With these criteria above, you won’t get it wrong when buying a water filter.


Why Do We recommend RO System?

I must admit that in WorldofWaterFilter.com, we are leading more towards reverse osmosis technology on drinking water filter. Let’s take a look at the advantage and disadvantage of the system:

Advantages:

Pure Water

Reverse osmosis water filter removes practically everything from the water leaving just pure water behind.

While some might concerned that it removes the beneficial minerals too, our argument is that the beneficial minerals appear in water are neglectable as compared to the mineral that is consume from food.

Micron Ratings

The micron ratings of reverse osmosis membrane is so fine, 0.00001 micron which practically capable of removing all contaminants.

It is 10000 times thinner than an average human hair. Most of the bacteria is capable of being filtered by the membrane leaving just clean water behind.

Storage Tank

Most of the reverse osmosis system comes with a storage tank which will help on getting clean water at a much faster pace.

Disadvantages:

Every type of products comes with the downside as well and this applies to all reverse osmosis filters.

Waste Water

Reverse osmosis system will drain out the water which can’t pass through the membrane. Those waste water normally have already been through at least 2 stages of filtering.

It might not be qualified for drinking, the waste water certainly can be channeled to other usages such as dishwashing, gardening and even laundry.

Zero Mineral In Water

There aren’t any beneficial minerals appear in the water unless some models come with a remineralization filter. This made it slightly acidic and bald taste.

According to WQA, the slight acidic filtered water from reverse osmosis system are safe to consume as post no harm to our body.

Bottomline: 

Despite the disadvantages, we still believe that the reverse osmosis technology creates some of the best under sink water filters in town based on the capability of removing contaminants.
