Benefits of Using a Small Water Filter Pitcher for Mini Fridge

Water Filter Pitchers are some of the most common water filtration devices that are highly affordable and help remove the unpleasant taste and odor of tap water that’s not ideal for drinking. Furthermore, these filtration products can also remove contaminants like lead, copper, cadmium, mercury, and more that can adversely affect your health. Most people prefer these pitchers because they’re cheaper and more effective than other filtration methods.

These easy-to-use water storage filtration systems are compact enough to fit in congested spaces like mini-fridges and allow you to store 5 to 7.5 cups of water. A water filter used in these pitchers lasts for two to four months, saving a lot of money on one-time-use plastic bottles and reducing pollution as this plastic is non-recyclable. Water Filter Pitchers are also highly portable and can be used to carry a higher capacity of water outdoors.

How to Choose the Best Small Water Filter Pitcher for Mini Fridge

Contaminants in Your Water

The term “contaminants” means the presence of other physical, chemical or biological molecules and compounds in water. Although most of the contaminants in your drinking water are often harmless in small amounts, it’s essential to check your tap water to avoid any severe health effects. A water filter pitcher does help to treat these contaminants, but it cannot filter every single impurity in your drinking water. So, make sure your pitcher can filter the particular contaminant present in higher levels before you purchase it.

Pitcher Capacity

The capacity of a water filter pitcher is generally measured by the number of standard cups full of water you can fill. These filters are available in a wide range of capacities, some large pitchers can hold more than 17 cups or 4 liters of water, but they demand a lot of space. If we talk about small water filter pitchers for mini-fridges, I recommend you to look for a small filtered water pitcher with at least 5 cups of water capacity.

Pitcher Size

When you don’t have a lot of space in your fridge to store a standard water filter pitcher, it becomes crucial to consider the dimensions of the filter you buy. There are high chances that a filter with a height above 12-13 inches won’t fit in many small-sized mini-refrigerators. So, verify that the device you pick is small enough to fit.

Pitcher Design

The design of a standard filter pitcher is very similar to that of a water jug. Most of these filters are made of BPA-free plastic, but you can find some premium pitchers that use glass, silicon body, and wood handle by paying an extra cost. It’s also equipped with a locking lid and an ergonomic handle that allows you to carry it around effortlessly.

Filter Lifespan

The lifespan of your pitcher’s filter depends on the frequency of usage and water quality. If you fill the water filter pitcher multiple times a day, it’ll need to be replaced sooner. A standard filter that most brands offer generally lasts one to two months, while some filters are designed for extended use and have a lifespan of more than four months. Most of these pitchers have an indicator to notify you when the filter requires replacement.

Filter Replacement Cost

Water filter pitchers are highly affordable, and so are the replacement filters. Most water filter pitcher brands manufacture their filters to ensure maximum filtration with high efficiency. The average price of one replacement filter is between 3-6$, depending on the brand and pitcher type.
