Buyer’s Guide

Lake Industries The Stainless Steel Countertop Water Purifier Filter (10 Micron Carbon Block)

Before purchasing your ideal countertop filter, there are various factors that you must look at. So let’s dive into those factors.

Filter Type

It is obvious that you are buying a countertop water filter, but these countertops are divided into two types. One that gets directly attached to the faucet of your sink and the other type is called water filter pitcher.

Here, we have discussed all the filters that are connected with the faucet except one that is Big Berkey.

So, it all depends on your needs which type of countertop filter you select.

If you have less space around your sink, then it is better to go with water pitchers, but one drawback of these systems is that you have to refill the water whenever it becomes empty. Also, it can only deliver a few cups of filtered water at a time.

On the other side, filters that are connected with the faucets provide constant filtered water and don’t require refilling. But the downside of these units is that they don’t make you aware of how much life of your filter is remaining.


Size is equally important to consider. If you are considering a filter that connects with a faucet, make sure that it can easily accommodate next to your sink faucet.

Types of contaminants removal

Before purchasing your ideal countertop filter unit, make sure that it can remove all the impurities that are present in your tap water. Most of the filters are quite effective in eliminating various harmful pollutants from water, but it is better to know what your filter is capable of. Some of the filters eliminate chlorine much better as compared to other units. Some are excellent in removing chloramine whereas some are weak or don’t possess the ability to remove it. Other than this, there are various filters that remove the essential minerals from the water that are calcium, magnesium, and potassium.

So, it is quite essential to know which type of filter you require according to the contaminants present in your water. It is mandatory to test the water first with the help of a water test kit before purchasing a filter.

Life of a filter cartridge

Another factor that needs your consideration is the life of a filter cartridge. Some cartridges can work well up to 6 months whereas some have the life span of a couple of years. Also, you may see the gallons of water written instead of the months or years.

So, it is best to have a unit that has a cartridge with excellent life span.

Installation/Ease of use

It is effortless to install and use the filters that get connected with faucets as compared to the water filter pitchers. But you can say that water filter pitchers are also easy to install.

If we talk about the ease of use, then the pitchers are not parallel to the faucet filters.

To use the faucet connected filters, all you need is to attach a filter to your faucet and turn the switch on to get the filtered water. On the other hand, water filter pitchers require some exercise. You have to regularly fill the pitcher to get the filtered water.

Other than this, if you want alkaline water, then there are some filters that turn the water more alkaline. Alkaline water is perfect for your health. These filter units use a special type of cartridges to make the water alkaline.

Steps required before buying a countertop filter

  • First of all, it is necessary to test your incoming water to know about the contaminants present. You must have a good water testing kit to get the idea about the type of contaminants available in your tap water.
  • After knowing about the contaminants, it is necessary to research which of them are more harmful for human consumption. Don’t listen to others as some people say lead is a more harmful contaminant. According to some, chlorine and chloramine are more dangerous. So, do your research to make sure what type of filter you require according to the hazardous contaminants present in your water.
  • Now, based on the harmful contaminants, select the best possible filter system that can prevent those impurities from reaching you.
