Adding Scents To Air Purifiers: Is It Safe?

Many people suffer from fragrance sensitivity, which can cause serious breathing problems, itchy eyes, sore throat, headaches, and sneezing. Some people opt for air purifiers to combat this issue, but can you put fragrance in an air purifier? While some may think that masking odors with another perfume is a good idea, it can actually aggravate chemical sensitivities. Instead, carbon filters are a good option for removing odors.

Carbon filters can help with fragrance sensitivity

Carbon filters are an effective solution for those with fragrance sensitivity. Fragrance sensitivity is a condition where one experiences a strong reaction to the chemical compounds that produce odors. This reaction can manifest in the respiratory system or on the skin, depending on where the aromatic substance is sprayed. Common products that can trigger fragrance sensitivity include body sprays, colognes, air fresheners, and certain scented cleaning products.

Carbon filters are frequently used in air purifiers to eliminate volatile organic compounds (VOCs) and are equally effective in removing odors from the air. They work by capturing odor-causing vapors and taking them out of circulation. Activated carbon acts as a sponge, trapping odor compounds inside and retaining them without changing size. This process, known as "adsorption," offers a more attractive place for the compounds to reside than circulating in the air.

For those with fragrance sensitivity, air purifiers with carbon filters can be a great solution. However, it is important to note that the amount of carbon in the filter and its quality are crucial factors in determining its effectiveness. Additionally, carbon filters work differently on different molecules, so the specific compounds in the air freshener will impact the filter's performance.

While carbon filters can be beneficial, it is worth mentioning that individuals with fragrance sensitivity may also need to take other measures, such as avoiding environments with strong odors or using nasal screens.

HEPA filters alone may not be enough to remove odours

HEPA filters are highly effective at capturing microscopic particles, including pollen, pet dander, dust mites, and even tobacco smoke. Their effectiveness rate is around 99.97% for particles larger than 0.3 microns. However, odour molecules are typically a hundred to a thousand times smaller, making them impossible to filter mechanically. Even the best HEPA filters cannot capture these smaller, odorous molecules, which mostly come from food.

HEPA filters are great for removing particles in the air, but they may not be sufficient to eliminate strong smells that have permeated surfaces, fabrics, carpets, furniture, or walls. For example, cigarette smoke has a strong smell that sticks to everything, and while a HEPA filter can help, it may not be enough on its own.

If you want to remove smells that come from gases, you will need to use a different type of filter alongside the HEPA filter. One option is to use an activated carbon filter, also called an activated charcoal filter. These filters use processed carbon with small pores, which increases the surface area available for absorption or chemical reactions. Activated carbon is highly effective at trapping certain chemicals and impurities, and it is generally considered the best option for eliminating unwanted smells.

Another option is to use UV light air purifiers, which have lamps that emit UVC and UVV wavelengths. The UVC wavelength destroys microorganisms, while UVV degrades chemicals by photo-oxidation, which are responsible for different types of unwanted odours.

Therefore, while HEPA filters are excellent for removing particles, they may not be enough to completely eliminate strong odours, especially those that come from gases or have permeated various surfaces. Combining HEPA filters with other technologies, such as activated carbon filters or UV light air purifiers, can provide a more comprehensive solution for removing unwanted smells.

Air purifiers with activated carbon can help with perfume smells

Air purifiers with activated carbon filters are effective at removing perfume smells from the air. The activated carbon filter captures and holds odor-causing molecules, preventing them from circulating in the air. This is because carbon filters are designed to adsorb VOCs and neutralize chemical fumes from cleaning products or paints.

In addition to removing perfume smells, air purifiers with activated carbon filters are also beneficial for removing other types of odors, such as those from cooking, pets, smoke, and household chemicals. The HEPA filter in these air purifiers captures airborne particles, while the activated carbon filter adsorbs odor molecules, ensuring that unwanted odors are eliminated.

When choosing an air purifier for addressing perfume smells, it is important to select a unit with deep carbon filtration to focus on heavy VOCs and odors. Some recommended air purifiers for this purpose include those with a deep-cleaning carbon filter system, such as the IQ Air Health Pro Plus or the Healthmate Junior.

Overall, air purifiers with activated carbon filters are an effective solution for reducing perfume smells and creating a fresh and comfortable indoor environment.

Wearable air purifiers can help with fragrance sensitivity

It is not advisable to put fragrance in your air purifier. However, if you are looking to improve the scent of a room, you could try using an essential oil diffuser.

If you are sensitive to fragrances, there are several options available to you. Firstly, you can try to avoid environments where you cannot control the smell, such as shopping centres or offices with no opening windows. If you are unable to avoid these spaces, you could try using nasal screens, which can provide some protection against fragrances.

Another option is to invest in a wearable air purifier, such as the Wein Air Supply or the Respiray Wear A+. These devices can be worn around your neck and provide a cloud of clean air around your mouth and nose, filtering out fragrances and other allergens. They are small, discreet, and easy to use, making them ideal for everyday use.

If you are looking for a more permanent solution for your home or office, you could try a larger air purifier with a carbon filter. These purifiers can remove the chemical compounds that trigger fragrance sensitivities, providing relief from symptoms such as coughing, sneezing, and skin rashes. When choosing a unit, look for one that offers deep carbon filtration to focus on heavy VOCs and odors.

It is important to note that fragrance sensitivity can closely resemble an allergic reaction, and it is always a good idea to consult a doctor if you are experiencing any adverse symptoms.

VOCs from perfumes can be removed with carbon filters

Volatile organic compounds (VOCs) are a large group of chemicals primarily composed of carbon. Some VOCs are harmless, but others can be extremely harmful to the human body, especially if you have asthma or chemical sensitivity. VOCs can be released into the air from everyday items in your home, such as mattresses, furniture, personal care products, cleaning agents, and paints. These invisible chemicals can be harmful to your health if left untackled, causing health problems such as headaches, nausea, and liver damage.

One way to reduce exposure to VOCs is to use an air purifier with a carbon filter. Carbon filters are specifically designed to remove gaseous elements from the air and may effectively remove VOCs in the short term. The key to their effectiveness lies in the process of adsorption, where pollutants stick to the outside of the tiny carbon particles in the filter’s adsorption bed. This allows carbon filters to capture airborne chemicals (gases) from the air.

However, there are a few limitations to carbon filters. Over time, the surface area of the carbon particles can become saturated, meaning the filter can no longer trap pollutants and may even begin to release previously trapped VOCs back into the air. Therefore, it is crucial to change carbon filters regularly to avoid off-gassing. Additionally, the ability of carbon filters to absorb and store pollutants is influenced by the humidity and ambient temperature of the room. Water molecules can compete for space in the adsorption bed, dislodging VOCs, and changes in temperature may cause VOCs to revert to a gas.

For effective removal of VOCs, it is recommended to use an air purifier with a heavy weight of carbon and a high airflow rate through the filter. This ensures that a large amount of VOCs can be captured quickly. Examples of suitable air purifiers include the IQ Air Health Pro Plus and the Healthmate Junior, which are specifically designed to address issues with smoke and cooking odors.

In summary, while carbon filters may not provide a permanent solution, they can be effective in reducing exposure to VOCs from perfumes and other sources in the short term. However, regular maintenance and replacement of the filters are necessary to ensure their continued effectiveness.
