Are you sure your home smells as good as you think it does? Unpleasant odors can rear their ugly heads when you least expect them, but you may not notice them due to a common nose-related issue called olfactory fatigue. When you are exposed to a smell for prolonged periods, your nose becomes desensitized to that smell.

While a HEPA filter in an air purifier can trap airborne allergens like dust and pollen, it is unable to obliterate the gases that cause odors or volatile organic compounds.
For these contaminants, you need an air purifier with an activated carbon filter.

Buying Guide
With regards to the space where you work or live in, there are a couple of things you could make peace with. The way it looks, how it is organized, lighting etc. can be compromised on, but an awful stench is very difficult to accept. For this reason you need to consider getting a Charcoal Air Purifier.
From basic to feature-laden, air purifiers come in various setups. For odor and chemical removal as well as overall excellent performance, we compiled a list of must-have features. If you want a few conveniences, we threw in a list of extras too.
Why Choose an Air Purifier at all?
Prior to understanding this type of appliance, it is crucial to make the decision whether you need one or not. The normal response would be yes!
Air purifiers are extraordinary appliances that help keep the air in your space healthy, whether it is an office or your home. It won’t keep the area tidy but it could improve the quality of it. Purifiers are normally considered by people that smoke or those that keep pets.
Smoking in an area will spread a distinct and unpleasant smell in that particular are. Pet hair and odor could be an unpleasant shock for your visitors with hypersensitivities.
A decent purifier, or even better, a charcoal air purifier would be the ideal answer for issues such as these.
Distinction between a Normal and a Charcoal Air Purifier
The normal type of purifier, usually fitted with a HEPA filter is sufficient to address the air issues. If you have problems with other issues like pet hair/odor, mites and dust, you probably need a charcoal air purifier. All the more so if you have a problem with smelly gasses and other things like germs or organisms.
A charcoal air purifier utilizes an extra filter that goes by the name of an activated carbon or otherwise an activated charcoal filter. If the charcoal or carbon is activated, a great many little holes open inside it. These little holes allows the activated carbon to “adsorb” the undesirable molecules which are in gas form.
By adsorption it would imply that the molecules cling to the filter, which then holds them back from being spread in the area. When it is activated, the charcoal and carbon filters behave in a similar way, despite the fact that the activation process is quite different.
This is what differentiates the charcoal air purifier from a typical purifier.
With regards to purchasing the correct charcoal air purifier, there are a few aspects that you should keep in mind.
Area
The area where it will be used is significant though. You need to know what your requirements are, so you don’t overspend and buy something which is too large for your little area. Purchase a unit that is ideal for the area you need it for, otherwise one that is adaptable and can cover different spaces you might have.
Picking the correct unit for the area you have will likewise not have the filters work too hard. They would then not need to be replaced so regularly and thus reduce your cost.
Activated Charcoal Filter
It is inconceivable for a purifier to dispose of the undesirable scents as well as their source, without using or considering a unit using an activated charcoal or activated carbon filtering system. This filtering system will also address and remove what is called “Volatile Organic Carbons (VOC’s)” from the air, and thus cleaning it properly.
HEPA Filter
A HEPA filtering system is just as important for general types of filtration requirements. High Efficiency Particulate Air (HEPA) is a mechanical type of filter which has a very fine mesh, typically with openings of about 0.3 microns.
At the point when air has gone through it, the mesh would capture every one of the particles greater than the size mentioned above. This is normally good enough to trap most of the dust-, pollen- and pet odor particles.
Particle Sensor
The particle sensor is fundamental in any purifier that works with charcoal as it would then operate automatically. This sensor determines how quick the fan ought to be. If you want to manually control it, the sensor will ask you whether you need the fan to be moving slow, fast or use the turbo setting which is available. This is when there is a lot of particles noticeable.
Noise Control
A lot of the purifiers normally run nonstop, particularly in the evening to guarantee clean air. For this reason the amount of noise it makes ought to be taken into consideration. You should also be aware of the fact that the noise levels would also be different, depending on which mode you have selected.
Filter Replacement Indicator
Many factors are considered which would indicate if the filter needs to be replaced. Factors like the level of air contamination, the day-to-day working hours and how good the quality of the air is would be considered. It is quite impossible to determine all of these factors and that is why an indicator makes light work of it, as it will simply tell you that it needs to be changed.
Extra Features
Aside from the previously mentioned built-in features, the purifier may well have some more features like the following:
- Ultra Violet-C light, to eliminate germs
- An Ionizer to improve the collection of molecule
- A timer for programming
- Capability to connect via Wi-Fi or an App
- Automatic and Sleep programs
The above mentioned could really make one of these purifiers much better that their counterparts.
Manufacturers integrate an ionizer or a UV-C light into some air purifiers. While an ionizer enhances the purifier’s particle-collection rate and an ultraviolet-C light kills germs on contact, neither is necessary if the air purifier has a HEPA and a charcoal filter.
Functions such as auto mode and sleep mode can save you a few minutes, but they don’t do anything that you can’t do yourself. A timer is another extra, but to get the maximum benefit from your air purifier, you should run it around the clock.
Even though a remote lets you control the air purifier from across the room, the same functions are accessible via the on-board panel.
Below are a couple of manners in which air purifiers manufactured with a filter made from carbon could be utilized in the home:
Carbon Can Be Treated to Target Specific Chemicals
Carbon which is activated can soak up many different smells and chemicals but it can’t eliminate all of it. Carbon isn’t really great at eliminating some regular synthetic substances like Hydrogen Sulfide or Formaldehyde.
In these circumstances, the carbon could be saturated with something like Potassium Iodide or otherwise mixed with Active Alumina to improve the retention capabilities.
This would imply that the minuscule spaces and cracks inside the carbon would now have an added compound that would react and neutralize the Hydrogen Sulfide or Formaldehyde, instead of just relying on the carbon to eliminate it.
As A Treatment for Multiple Chemical Sensitivity
There are people that suffer from Multiple Chemical Sensitivity (MCS) which means that they are hypersensitive to some chemicals in the air. Things like some cleaning chemicals, perfumes and even gas released from materials used for building can seriously bother somebody suffering from MCS.
For these individuals, an air purifier with a lot of activated carbon can be utilized to eliminate these nuisances from your home. The quality of the air will much better for everybody and particularly for those individuals who have a problem with Asthma, problems with dust and those with a compromised immune system like infants, kids, and some older people.
FAQs
How Long Does a Carbon Filter Last?
Even though the adsorption area on a carbon filter is rather extensive, it’s not limitless. When all the pores are filled with pollutants, the filter can no longer do its job, and neither can the air purifier.
Unfortunately, there is no foolproof method of determining whether an activated carbon filter is saturated, and the lifespan of a carbon filter varies due to filter size and surrounding air quality.
A strange odor is indicative of a full carbon filter; however, a smell is not always present. The best practice is to follow the air purifier manufacturer’s instructions for filter maintenance.
If your air purifier often detects poor indoor air quality, you should change the carbon filter sooner.
What Are Volatile Organic Compounds?
Volatile organic compounds, or VOCs, are gases and vapors that come from a staggering number of sources. Many indoor sources may be products that you use regularly. For example, burning wood in your fireplace releases VOCs into the air.
If you are a DIYer, you can be exposed to VOCs when painting, laying carpet or using certain building materials. Art supplies, air fresheners, and cigarettes are three more common indoor VOC culprits.
Whether or not you may experience symptoms related to VOCs depends on several factors, including the toxicity level of the VOC, the volume of the VOC that’s airborne, the length of exposure and your personal health.
Symptoms of VOC exposure range from mild ones like headaches, throat irritation, and nausea to life-threatening ones such as cancer, organ failure and nervous system damage.
How Is an Air Filter Carbon Activated?
The activation process for carbon is a little different. Like one of the methods used for charcoal, steam is involved. Instead of surrounding the carbon with steam, manufacturers inject the steam into the carbon, which creates extra-small pores needed for adsorption.
Often, carbon undergoes a chemical treatment after it’s activated to boost its contaminant-trapping ability.
How Is Charcoal Activated?
For charcoal, there are two methods that manufacturers employ. The first method involves steam, which envelops the charcoal as it’s heated to a temperature as high as 2,192 degrees Fahrenheit.
The second method uses phosphoric acid in place of steam, which is injected into the charcoal. Then, the charcoal is heated to a temperature of up to 1,652 degrees Fahrenheit.
With acid, it doesn’t take as long for the charcoal to complete the activation process.
However, steam-only activation eliminates the minute risk of trace elements. Either way, the charcoal’s pores shrink after activation, leading to a larger adsorption surface.
What Materials Are Used to Make Carbon Filters?
Manufacturers of carbon, or charcoal, filters can choose from many sources to create their products. Coal, charcoal, and wood are the three most common sources as they are readily available and cost-effective in terms of production.
However, some manufacturers opt for other materials such as bamboo, coconut shells, peat, petroleum or sawdust.
The creation of activated carbon does not solely depend on the above-mentioned raw materials. Manufacturers have experienced success with olive stones, palm kernels, and walnut shells. However, these materials are harder to obtain in bulk.
Is Activated Charcoal Different From Activated Carbon?
Carbon filters, charcoal filters – Many people believe that these are not the same type of filter. This belief stems from differences in carbon’s and charcoal’s activation processes. In spite of that distinction, they share similar properties.
Therefore, you can correctly interchange for activated charcoal for activated carbon in the scope of filtration because both terms refer to the same filter.
How Do Activated Carbon Filters Work?
To create a carbon filter, manufacturers use coal or other substances, putting them through the activation process. Once that process is complete, a vast number of microscopic pores form, providing a significant amount of surface area for capturing gaseous particles.
In fact, a single pound of activated carbon has enough pores to cover 100 acres.
When used in an air purifier, a carbon filter traps odor-causing particles via adsorption, which causes the particles to adhere to the exterior of the filter. This is not the same as absorption. With absorption, a substance is contained within an object.
