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.

Best Charcoal Air Purifiers

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.

A Quick Guide to Shopping for 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.

Must-Haves

You cannot get rid of unpleasant smells or dangerous VOCs without an activated charcoal filter. However, your air purifier should also have a HEPA filter for comprehensive purification. You also want the filters to last for a long time to avoid the cost of monthly replacements, and make sure the air purifier you choose is suited for the size of the room.

Best Activated Carbon Air Purifiers

A particle sensor helps you select the correct fan setting on multi-speed models, and a low decibel output ensures the purifier won’t be a nuisance. Since several variables determine a carbon filter’s lifespan, a filter change indicator is extremely helpful.

Extras

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.

Charcoal Air Purifier FAQ

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.

Best Charcoal Air Purifiers

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.
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.

Best Home Charcoal Air Purifiers

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.

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.
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.

Top Charcoal Air Purifiers

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.
