What do you need to look before buying a countertop water filter


As the name applies countertop water filter are placed on the sinktop or table top.

You need adequate space on top of your counter to place the filter.

If you do not have enough space on your countertop you can decide to have a desk or table to place your filter. If not so you might consider installing other types of water filters like under sink water filter or the faucet water filter

Impurities the system can filter

Every water source has different contaminants and each countertop water filter brand is meant to remove specific contaminants.

Before buying know the contaminants that are in your water so that you know the right system to filter the impurities.

How much water your family consume every day

The most countertop water filter can treat water for a family of six.

Also, the more water you consume the more frequent you will have to change the filter.

The more people you have in your family the more frequent you will be required to change the filter and this might be expensive compared to other types of water filters.


Countertop water filters use cartridges and require to be replaced after a given period of time.

Most of the brands require cartridge to be replaced every four months up to one year.

Choose the product that you can easily change stress free, the replacement filter is available and the cost is affordable.

I read somewhere a customer bought a countertop water filter that was costing $59 but the replacement filter was not easily available and wherever you find it will cost four times more than the system.

Types of countertop water filter

There are different types of countertop water filters that you can choose from. This include:

  1. Countertop gravity water filter 
Countertop Water Filter Dispenser

A gravity dispenser uses gravity to pull water through the filter.

It has an upper chamber and lower chamber.

The upper chamber is where contaminated water is poured then passes through the filter which is between lower and upper.

The filtered water will flow to the lower chamber where is stored.

The filter dispenser does not require electricity to operate, do not need any installation; it can sit on any countertop either in the office or kitchen.

The only disadvantage is keeping on adding water and waiting for a couple of hours for the whole process.
