1.     Why Does My Fridge Smell Bad?

Many factors can contribute to a fridge or freezer smelling unpleasant over time. The following are a few reasons why your fridge or freezer smells bad:

  • Microbes

These tiny bacteria are the root cause of foul odors inside many fridges and freezers. Mold and other microbial germs can slowly form in fridges and freezers over time, which eventually leads to an infestation. Although invisible to the naked eye, one of the clearest indications of a microbial infestation in your fridge is that tell-tale unpleasant smell we all know.

Where do mold and microbes come from? The short answer is moisture and humidity – both mold and bacteria absolutely thrive in moist, humid environments.

  • Moisture and Humidity

One of the most obvious causes of moisture is spilled food or drink, which can contribute to internal condensation, which in turn raises humidity levels inside the fridge. Fridges and freezers in humid climates are also naturally more susceptible to bad smells, as external humidity can raise a fridge’s internal humidity levels as it’s opened and closed throughout the day.

  • Spoiled and Expired Food Items

Another source of mold and bacteria is spoiled or expired food items. Even if they are canned and properly stored, once perishable goods start to go bad, microscopic bacteria and fungus will eventually find a way out and begin to spread and ultimately result in an infestation.

As we mentioned earlier, such an infestation can lead to foul odors in fridges and freezers which can be very problematic, especially as they can infect any nearby fresh produce, meat or dairy products.

Luckily for you, it is very easy to get rid of any unpleasant fridge odors. All you need are the right tools to get the job done fast. Next, we’ll be going over a few steps you can take to quickly get rid of odors in your fridge or freezers.

  • Other Possible Causes of Bad Refrigerator Odors

Aside from those already mentioned, damaged filters, bacterial buildup in the drainage system or a could also cause your fridge or freezer to smell bad.


2.     How to Get Rid of Refrigerator Smells and Fridge Odors

The best and easiest way to get rid of repulsive fridge smells is by using specialized fridge deodorizers. These are small, yet effective gadgets that can get rid of smells quickly without the need for any harmful chemical that can cause long-term health problems. Using refrigerator deodorizers, however, is just one way to get rid of unpleasant odors and before we go into too much detail discussing their effectiveness, it’s worth mentioning a few alternative methods to deal with unpleasant fridge smells.

  • Lowering the Temperature

One of the first things you should try after noticing any bad smells in your fridge or freezer is to simply lower the temperature. Lowering the temperature is one of the most effective ways to freshen up and deodorize your fridge or freezer. Ideally, a fridge should be set to between 35° F and 37 °, though sometimes this may not be cool enough to slow down the buildup of moisture and condensation, especially if you live in a humid place.

  • It’s worth noting here that the internal temperature gauges in fridges are sometimes inaccurate, and some fridges don’t have one at all – so an easy way of verifying your fridge’s internal temperature is to simply purchase a digital thermometer. Get Rid of Any Spoiled or Expired Items

Check your fridge for any spoiled or expired food products, particularly anything stored in the side doors. It’s surprisingly easy to forget about when the food in your fridge expires! Moreover, food stored in side doors tends to spoil more easily and even if the food doesn’t show any visible signs of rot, products like fresh fruit, dairy, and produce could already be harboring nasty bacteria.

As soon as you finish checking the door, make your way to the rest of your fridge. Do not hesitate to smell and check every bit of food inside to ensure its freshness and check the expiry dates to stay up to date on what’s about to spoil.

  • Fridge Deodorizers

As we mentioned earlier, fridge deodorizers are perhaps the most effective way of getting rid of unpleasant fridge odors. You can also use products like silica mats to help eliminate odors. Silica mats can help keep fresh produce fresher for longer and slow down food spoilage. What’s more, silica mats are typically cheap, so there’s no need to worry about spending a ton of money to keep your fridge smelling fresh. Another cheap alternative is to use coffee grounds, though their effects may vary depending on the severity of the odor.

Fridge deodorizers, on the other hand, are a cheap and easy solution to keeping the entire fridge smelling fresh. Simply remove them from their packaging, place them on a dish and into your fridge to start absorbing odors right away! You can also find fridge deodorizers made out of natural materials like charcoal, which are healthier for both you and the environment.

  • Deep Cleaning

Deep cleaning is also an effective, yet a time-consuming, way of eliminating unpleasant odors in your fridge. Be sure to thaw your fridge thoroughly before cleaning it out and airing it out after you’re done cleaning. Airing out your fridge after you’ve cleaned it is important to completely get rid of any foul smells, as well as any residual smells from cleaning products.

  • Deal with Any Spills Immediately

As soon as something in your fridge spills or leaks, it’s important to immediately remove the item and immediately clean up any spilled liquid. Even though refrigerators nowadays have spill-proof shelves (which tin themselves are a good investment) it’s still important to tackle spills and leaks as soon as they happen in order to avoid the possible growth and buildup of mold and bacteria.

These spill-proof refrigerators will be a good investment for sure.

  • Get Professional Help

If smells persist even after thoroughly cleaning the fridge, or perhaps you simply don’t have the time to spend hours cleaning it out, calling in a professional is also another viable option. Having your refrigerator professionally cleaned could also serve to extend its service life, and such professionals might even be able to better advise you on recommended maintenance and service procedures.

2.1  More Ways to Prevent and Get Rid of Bad Smells in Your Fridge

Aside from those already mentioned above, there are still more ways to prevent and get rid of bad smells in your fridge. A few of them have been listed below for your convenience:

Leave Fresh Scents

If you’re looking for natural ways to get rid of odors inside your refrigerator, you can start by making sure that you leave fresh scents behind. One way would be to dip cotton balls in a bowl of vanilla extract leave them in your fridge for a few hours. When it’s time to remove them, your fridge will be left smelling clean and fresh. You can also substitute cotton balls soaked in vanilla for orange wedges or pieces of orange peel.

Learn the Basics of Proper Food Storage

By learning what foods leave strong smells and separating them, or removing them altogether, from other food stored in your fridge you can minimize the chances of strong smells emanating from such foods and spreading throughout your fridge. This does, however, take a bit of practice to get right and still doesn’t account for strong smells caused by mold or other microbes.

Use Airtight Containers

Keeping food in airtight containers and storing them in designated sections is certainly an effective way of preventing bad smells in your fridge. What’s more, modern fridges nowadays come with specially designated compartments to store certain foods, which makes things a lot easier.

Maintain Proper Airflow and Maximize Fridge Space

Regulating and maximizing airflow inside your fridge helps prevent the buildup of microbes and mold, as does making efficient use of the space you have in your fridge.


3.     What is the Best Fridge and Refrigerator Deodorizer?

As we mentioned earlier, one of the best ways to get rid of unpleasant refrigerator smells would be to use fridge deodorizers. However, a few questions still remain. What is the best kind of fridge deodorizer? How to choose the best deodorizer for your fridge? To answer these yourself, it’s best to understand the basic deodorizing process first.

Most deodorizers work by absorbing any odors emitted by refrigerator contents, thus eliminating unpleasant smells and keeping food fresh. The best ones are those that offer superior odor absorption while leaving no scents of their own. When it comes to fridge deodorizers, there is a range of choices including simple baking soda and activated charcoal deodorizes.

3.1  Baking Soda as a Refrigerator Deodorizer

This natural product works well to eliminate bad smells in places like fridges and all you need to do is fill a small container with baking soda and leave the container in the area you want to purify for around 24 hours. While somewhat effective, baking soda is rarely useful against persistent smells and can even damage or stain certain surfaces and metals like aluminum – not to mention that containers need to be replaced on a regular basis and be quite messy if accidentally knocked over. The use of baking soda is only recommended for mild smells, more stubborn/pungent smells typically require the use of alternative products like charcoal deodorizers, which we’ll be covering next.

3.2  Bamboo Charcoal Fridge Deodorizers

Bamboo Charcoal Fridge Deodorizers

Bamboo charcoal deodorizers typically come in the form of a bag that you can easily place inside your refrigerator to absorb odors. Bamboo charcoal works to absorb odors through its active pores; gas particles cling to the surface of the charcoal through adsorption and eventually make their way inside the pores – leaving your fridge smelling fresh and clean.

In fact, most charcoal fridge deodorizers can effectively eliminate unpleasant all traces of smell in a fridge in just a few hours. They’re also reusable and all you need to do to “recharge” your bamboo charcoal deodorizer is to leave it out in the sun for a few hours every month or so. Bamboo charcoal bags last approximately one year, and after a year of regular use, can be simply cut open and sprinkled onto the soil to provide effective moisture regulation.

3.3  Activated Charcoal Fridge Deodorizers

Activated Charcoal Fridge Deodorizers

Activated charcoal fridge deodorizers work similarly to bamboo charcoal bags, with only a few minor differences.

Activated charcoal is charcoal that has gone through a special process to become more absorbent and porous. It has a larger surface area when compared with other types of charcoal, which allows it to absorb more.

Another advantage of using activated charcoal is that it contains pure carbon, which helps it absorb more organic molecules. Because of this, it can effectively absorb even the foulest smelling odors from types of food in refrigerators without any trouble whatsoever.

How Do Activated Charcoal Fridge Deodorizers Work?

How Do Activated Charcoal Fridge Deodorizers Work

Charcoal is activated through careful, constant exposure to high temperatures. The process increases the charcoal’s absorption and adsorption capabilities, which allows it to better get rid of the airborne particles that can cause strong, unpleasant odors in fridges.

These positively charged airborne particles are drawn to and stick to the activated charcoal’s negative ions and are then absorbed, effectively eliminating the source of any foul smells in the vicinity and resulting in a cleaner, fresher smelling fridge.

Like other types of charcoal fridge deodorizers, activated charcoal is easily rechargeable and can be reused for up to a year by simply exposing it to direct sunlight for a few hours every so often.

3.4  Nano Crystalline Fridge Deodorizers

Nano crystalline deodorizers are a relatively new addition to the world of fridge deodorizers. As their name implies, they rely on special nano mineral crystals to effectively deodorize fridges.

Nano Crystalline Fridge Deodorizers

3.4.1 Raw Materials

Nano crystalline fridge deodorizers are made from an all-natural mixture of minerals and active charcoal. To give you an idea of what goes into these fascinating products, we’ve listed a few of the most common minerals used in nano crystalline fridge deodorizers, along with their pore diameters:  a mixture of active charcoal

Raw Materials

  • Sepiolite (Meerschaum) – 0.3 to 1.1 NM
  • Attapulgite – 0.37 – 0.67 NM
  • Clay – 0.3 to 0.6 NM
  • Diatomite – 100 to 1000 NM

Why is Pore Diameter Important?

The pore diameter is important as it determines a mineral’s absorption rate. Put simply, the larger the pore diameter, the more porous the mineral is, and thus the more absorbent it is.  The combination of these minerals with the nano crystalline particles allows them to work much more effectively than their charcoal or even activated charcoal counterparts.

In this case, thanks to its large pore diameter, Diatomite is the most absorbent mineral used in nano crystalline fridge deodorizers and is the main reason they’re able to get rid of foul smells in fridges more effectively.

Nano crystalline fridge deodorizers are also non-toxic, making them safe to use near organic food products.  They’re also efficient in absorbing chemical smells, such as those emitted by food products that use excessive food coloring.

3.4.2 Uses


Nano crystalline  air purifiers are one of the newest and most popular methods to completely eliminate dangerous formaldehyde smoke smells, foul odors, and other known harmful airborne chemicals and odors in enclosed spaces. It’s safe to say that they’re more powerful than bamboo charcoal and activated charcoal combined. Furthermore, just like their bamboo charcoal and activated charcoal counterparts, nano crystalline fridge deodorizers are reusable for up to four weeks at a time and can be charged up to six times before being replaced.

Nano crystalline deodorizer bags work great when used in any small, enclosed environment, including in:

  • Pantries and cupboards.
  • Closets.
  • Hotels rooms.
  • Vehicles.

Additional Benefits of Nano Crystalline Fridge Deodorizers

Nano crystalline fridge deodorizers work for up to six months can be stored for up to two years, so long as their seal is not broken. As mentioned above, nano crystalline deodorizer bags can be recharged and this is done by simply leaving the bags in direct sunlight for a few hours, or by placing the bags inside a 600-Watt microwave for 6 minutes.

Nano crystalline fridge freezer deodorizers are the most convenient type of deodorizers to be used in a home setting. Most of them come equipped with two or more suction cups, which allow them to be easily stuck onto fridge or freezer walls to save space.

Additional Benefits of Nano Crystalline Fridge Deodorizers

Below are a few more advantages of using our nano crystalline fridge deodorizers.

  • Non-scented.
  • Constructed out of natural, non-toxic and ecofriendly materials.

The correct term is actually “nanocrystalline”, but I left it like this since it’s written this way on the product pictures on your site. If they are just sample pictures it might be worth changing it to the correct term, otherwise I don’t think it’d be a big deal.


4.      Choosing A Good Fridge Deodorizer Manufacturer
