Top Tips to Consider When Buying a Water Filter for Mini Fridge Units

There are a lot of water filters on the market. Some offer really good water filtering properties and some are not worth the money you pay for them. Here are some tips you should consider when buying a water filter for mini fridge. 

Type of Water Contaminant

Do you know what exactly you want to filter out of your drinking water? If you don’t, this is the first place to start before buying your water filter. If unfiltered water is red or appears like it’s contaminated by iron, it most likely is.

The safest bet is to carry out a test using a test kit or strip that can easily help you determine contaminants present in the water. 

Purpose of the Water Filter

Some water filters are designed to work for particular contaminants while some will filter out almost all toxic compounds and heavy metals from water.

Others may also improve the taste of the water, remove the chlorine taste, and help to balance the pH levels. This makes it important to know the exact type of contaminants in your running tap water.

Water Filter Pitcher Certification

Certification is necessary for all standard filter pitchers for mini-fridges. Without individual certification or NSF/ANSI certification, there is no way to prove that the filter works as described.

Standard certification for water filters in the United States is regulated by NSF. Independent certification can equally be good, just make sure to do your research to make sure the independent certification is legitimate. 

Water Filter Design and Approximate Size

One of the top considerations for many is the size and design of the water filter pitcher itself. Is it small enough to fit inside your mini-fridge? Is the design user-friendly? How many cups of water can it hold in one go? These are all questions you should consider before making a purchase.

Frequency of Replacement Filters

You might be asking: how often will I need to replace the filter of the unit? The filters of the pitcher don’t last very long so they will need to be replaced frequently.

To save cost in the long run, buy a filter that will serve you for 3-6 months before you have to buy replacement filters. Also, the frequency of replacement is determined by how frequently you use the water filter.

Quality of the Water Filter

Quality considerations are last but not least. The most recommended tip to follow if you need a water filter for your mini-fridge is to pick a high-quality water filter with an excellent build. Avoid cheap plastic filters or BPA plastic filters at all costs. Buy BPA-Free plastic instead.
