Contaminations Removing Capacity
Different under sink water filter comes with different capacities to filter out the contaminants, some of the RO filters come with an extremely powerful filter to capture even more than 1000 chemicals, however, some under sink filter comes with normal range filters which are only able to remove some selected chemicals.
We suggest you check the filtrating capacity of the filter you are buying. If you have selected a filter that is not capable to filter out the well water, you have probably wasted your money if we’re looking for one. We have covered models in our reviews that can filter well water too.
Keep checking out the filter whether it will remove the chemicals you want to remove or not
Micron rating defines what size of particle a particular filter will be able to capture. Some filter comes with an extremely low micron rating of 0.0001 which will be able to capture even very small bacteria as well. While others comes with a 0.5 microns rating which will not be able to remove tiny chemicals.
According to our research, most of the under sink water filter comes with high micron rating because they are designed for biological safe cities. They are not designed to purify high contaminated well’s water with lots of tiny bacteria, still few options are available in the market to facilitate the consumers.
You can select a low micron rating filter from our list which will be able to purify both tap and well water, keep in mind if your water is not that much-contaminated keep use ordinary water filters to avoid the excessive cost.
NOTE: leaser the micron rating greater the water quality.
Nothing is more frustrating than waiting for a glass of pure water for a long time, believe me, it will exhaust you.
Selecting an under sink water filter with sufficient water pressure is very much important to save your time. Though under sink filters are designed to provide more pressure as compared to others, still, you have to select according to your needs.
The Capacity for Supplying Water
Different underwater filter comes with different capacity to supply premium water per days. Some water filterS can supply 75 gallons per day, while others can supply 18 to 20 gallons per day, make sure to select the one according to your needs.
Don’t choose a very large unit if you need low GPM. The cost of maintenance and water bills will be high if the unit is large in size & capacity.
This is the most important factor. You have to check out before buying an under sink water filter, most of the traditional RO filters comes with a high water wastage ratio of 5:1, 4:1, etc. which will cause of a nerve wreaking water bills.
NOTE: 5:1 means you will get 1-gallon of premium water by wasting 5 gallons of water which is very high.
Don’t get confused, thanks to new technologies that bring down the waste and pure water ratio from 5:1 to 2:1 or even 1:1. Know you will get extremely efficient under sink water filters like Waterdrop RO Reverse Osmosis Drinking Water Filtration System, CuZn UC-200 Under Counter Water Filter, etc.
Lower the wastewater and pure water ratio lower the cost of water bills environmental impacts etc, make sure to select a unit with the lowest wastewater to pure water ratio.
We have shortlisted each of our products carefully to avoid lots of water wastage feel free to select from them.
Selective Filtrations (Healthy Mineral Addition)
Selective filtration will leave essential minerals that are beneficial for your brain and bones, without these adequate minerals you will drink dead water without beneficial minerals.
We suggest you choose an under sink water filter with selective filtration technology to get essential minerals, we have listed some of the best under sink water filters with intelligent selective filtration.
Filter Quality and Lifespan
The filter is the backbone of every water filter not only an under-sink unit. It should be durable and efficient to capture all hazardous chemicals instantly, to provide safe and premium water for a lifetime.
Moreover, its life span is very important, different filters come with a different lifespan like 6 months, 1 year, and even 3 years, select the most durable one to avoid rapidly changing.
Why It Is Important:
- Cartage with impressive longevity built from quality material will be able to purify water more efficiently.
- Another major benefit is you will save maintenance costs as well.
NOTE: Examine the filter after a certain time, if the manufacturer claims that this will last for 1 year, keep monitoring it right after 8 months because they have tested that filter with municipal water which is not as same as your water.
Your water may have more contaminations, keep examine the water filter to get contamination-free water.
Stages of Purification’s
The unit with more stages of purification will be more powerful than an ordinary 2 or 3 stages filter but, you have to pay more, in terms of initial cost, maintenance water, and bills, etc.
Please choose according to the usage and biological condition of the water, if you want to filter out the well water you need to purchase a multistage filter to get more purification. However, if you want to purify tap water which is already biologically safe, then you need to buy a 2 or 3 stage filter to avoid the excessive cost.
We suggest you examine the water before deciding to buy a unit, this will help you to select the best under sink water filter within the mid-range price tag. Just do some biological tests of water from your nearest water treatment labs and you are good to go.
This is not a very important factor to consider but we have listed this for fitness freaks, those who are involved in fitness they want their water with a certain pH level (alkalinity).
Some under-sink water filters come with pH filters to adjust the acidity and alkalinity of water after purification which is amazing because natural water itself has an elevated pH level which is beneficial for the human body to digest food. It is also beneficial for bones.
Of course, you have to pay some more bucks to get the unit with a pH filter, still, you got cheap options with selective filtration technology to leave healthy minerals.
If you are a real fitness lover you have to select this technology.
Ease of Installation and Maintenance
Easy installation and maintenance will save you lots of time and money, you don’t need to hire a plumber to install it. You only need to follow the instruction of the manual to install and maintain it.
Furthermore, you can examine the leakage problem and fix it as well, that is why we suggest you pick an under sink water filter which can be installed and maintain within a few minutes.
As the matter of fact, we all believe that expensive under-sink water filters will last longer, provide premium contamination-free water with adequate minerals, etc. isn’t it?
To some extent we are right we need to spend more to get more premium quality under sink water filter with lots of features, but keep in mind we have to select a unit according to the biological condition of water and usage.
People purchase very expensive under sink water filters unnecessarily, they need a limited flow of water, their inlet water is biologically safe than why they need an expensive filter, they can do their work with a budget-friendly filter as well.
Keep in mind expensive filters with lots of filtrations stages will need more maintenance costs as well, always choose a system that is feasible for your home. Avoid unnecessary fuss.
