Budget Pick – iSpring CKC1C Countertop Water Filtration System

iSpring CKC1C Countertop Water Filtration System

The iSpring countertop water filter has three major selling points; it’s small, easy to maintain and very effective. It’s one of the few countertop water filters that come with a 10-inch filter cartridge.

Its filter is designed for removing tons of water contaminants including chlorine, odor, rust, silt, sand and other sediments. More importantly, it effectively eliminates VOCs from your water. Its compact size ensures that it doesn’t take much space on your countertop.

Inside this unit, you’ll find a 5-micron carbon filter. Although it’s not as powerful as a 1-micron filter, it’s very effective – at least 95% effective in removing contaminants from water.

  • Large 10-inch filter cartridge.
  • Small size.
  • Two color options.


  • It effectively removes chlorine, odor, VOCs etc. from the water.

  • The unit is outrightly easy to install – in fact, it takes less than 10 minutes to install it.
  • It removes a lot of contaminants from the water but leaves out important minerals like magnesium.
  • The filter has a lifespan of 450 gallons and is easy to change.
  • It’s available in two colors.


  • The filters are a bit expensive when compared to filters for other units.

The filter has a lifespan of 450 gallons which is low when compared to the other units in our list. However, it doesn’t take away its ability to remove contaminants.

Whilst removing contaminants from your water, the unit doesn’t remove important minerals like magnesium which is important to the body. It also doesn’t remove calcium. If you don’t like calcium in your water, you should install a water softener to take care of it.

Buying Guide: Best Countertop Water Filter Systems

Because of the convenience they offer, countertop water filters are fast becoming the recommended choice for water filters. There are a lot of products to choose from – some are worth it while the others are not.

In this section of the article, we’ll take a look at the factors to consider when buying a countertop water filter. When you’re done reading this buying guide, you’ll be able to make the right choice that’ll suit your needs and that of your family. We also recommend looking at some faucet water filters if you plan on putting this in your kitchen.

Type Of Countertop Water Filters

There are two different types of countertop water filters.

  1. Water Filter Pitchers: This refers to the jug like water container that comes with its own filters and filters water entering it. Some are designed to filter the water as it leaves. Water filter pitchers are compact sized and can hold at most 25 cups of water (8 oz. standard). We reviewed the best water filter pitchers here.
  2. Conventional Countertop Water Filters: This type of water filter comes in two different variants; a tank model or the tankless model. As the name implies, the tank models come with their own tanks which can hold a limited amount of water. On the other hand, the tankless models are directly connected to the water source. This is where the faucet water filter falls under.

A lot of individuals classify the faucet water filter as a countertop water filter. Well, here at Water Filter IQ, we know better which is why we didn’t include it. If you’re interested in owning a faucet water filter, here’s our review on it.

Having decided which type to buy, you should also consider the following.


You should take note of the amount of space you have left on your countertop if you’re interested in getting the models with a tank. This will help you to plan accordingly and leave ample space for other things on your countertop.

Size can really be a deal breaker if you don’t take it seriously.


Getting a tank model? What’s the capacity? How often do you use it? How many persons will be using it? These are some of the important questions you need to ask with regards to capacity.

The larger the household, the larger the size of the unit you’ll need.

Filter lifespan

At this juncture, we expect that you’ve seen a handful of units you’re interested in. Now, take a look at their filter lifespan and compare. Opt for models with higher filter lifespan.

In addition to that, getting a replacement filter shouldn’t be as difficult as finding an eagle’s egg. We recommend buying the replacement filters in bulk to ensure that you don’t run out of filters – and you’ll get to save money too.

Contaminants you want to remove

Knowing the contaminants in your water can go a long way in helping you select the perfect water filter. If your water is directly sourced from the city, a trip to the municipality office will furnish you with the list of contaminants in your water.

Most manufacturers indicate the type of contaminants their products can remove. Crosscheck with your list to see if the contaminants in your water can be removed by the countertop water filter or simply measure the drop in Total Dissolved Solids (TDS).


Although most countertop water filters don’t require installation e.g. the water filter pitcher, the ones that do should be done by either a professional or a DIY enthusiast who has experience in such installations.

This will ensure that the product isn’t damaged and will prevent the warranty from being voided.

Look out for certifications

Certifications help to build consumer confidence in products. Look out for certifications for the filter as well as the water filter in general.


For the majority of households, you can ensure 100% safety and great taste with our pick for the best countertop water filter: the Big Berkey Countertop Filter System.

You can also select the AquaTru Countertop RO System to get full reverse osmosis at an affordable price.
