Why Half Filled Dashboard Bag of Impregnated Activated Carbon,Natural Zeolites,Molecular Sieves Works Properly Inside The Cars

How many years will the combination of dashboard bag impregnated activated carbon,natural zeolites,molecular sieves purifies inside the cars ?

Of course. This is an excellent question that gets to the heart of how these passive air purifiers work. The short answer is:

Typically, 1 -1.5 years. However, this is a general estimate and the actual lifespan can vary significantly based on several factors.

Here’s a detailed breakdown of why and what influences this timeframe.

Understanding the Technology

First, it's important to know that these dashboard bags are not "filters" in the active sense (like a APHEPA filter in your home that air is forced through). They are passive air purifiers that work through adsorption (where molecules stick to the surface of a material).

· Impregnated Activated Carbon: The "impregnated" part means the carbon is treated with additional chemicals (like Potassium Permanganate, Zinc, Copper (total 9 metal oxides etc etc)) to target specific gases (e.g., 40 Toxic Gases, TVOCs, Formaldehyde, Benzene etc etc, and other gases and odors from Plastics, Upholstery, and Exhaust Fumes.This coating can be used up over time, even if the carbon itself isn't fully saturated.

· Zeolites & Molecular Sieves: These are highly porous crystalline materials. They are particularly good at trapping 40 Toxic Gases, Higher Molecular VOCs, Lower Molecular VOCs and Moisture (water vapor), which helps prevent the "new car smell" and reduces fogging on windows.They also adsorb all various gases.

· Plant Nanolites,Cell Membranes,Electrons Mix Treatment: This unique nano-coating technology, applied to impregnated activated carbon, natural zeolites, and molecular sieves, enhances their adsorption holding capacity by effectively binding all 40 toxic gas molecules to the surface with 100 times greater strength.

Factors That Determine Lifespan

The "purifying" action doesn't suddenly stop after a set time; it gradually diminishes as the pores in the materials become filled with captured molecules. The lifespan depends entirely on the total pollutant load it is exposed to. Normal impregnated carbon only having low capacity to hold odors and toxic gases.Thatswhy it only last for 2- 3 months.

1. Air Quality & Environment:

· New Car vs. Old Car: A brand-new car off-gasses a huge amount of VOCs from its plastics, adhesives, and fabrics. A bag in a new car will saturate much faster (perhaps in 6 -12 months) than one in a 5-year-old car.

· Urban vs. Rural Driving: Sitting in heavy traffic daily exposes the bag to far more exhaust fumes and pollutants than occasional rural driving.

· Climate: Hot, sunny climates accelerate the off-gassing process from the car's interior. Parking in the sun every day will significantly shorten the bag's effective life.

· Smoking/Eating in Car: If you smoke or frequently eat in the car, the bag will have to adsorb those additional strong odors, reducing its lifespan.

2. Product Quality:

· Amount of Material: A small 75 g or 150 g bag containing standard impregnated activated carbon, zeolites, or molecular sieves—without PLANTORIGEN PLANT NANOLITES, ELECTRONS & MEMBRANE MIX(nano coating technology)—hung from the rearview mirror or placed on the dashboard of a large SUV or small car will not work properly.

· Quality of Materials: Without PLANTORIGEN PLANT NANOLITES, ELECTRONS & MEMBRANE MIX(nano coating technology), the adsorption performance of these materials degrades in under 3 months. This proprietary nano-coating technology—applied to impregnated activated carbon, natural zeolites, and molecular sieves—boosts their adsorption holding capacity by binding all 40 toxic gas molecules to the surface with 100x times greater strength.

3. Exposure:

· Airflow:

Conventional 75 g rearview mirror-hanging impregnated activated carbon bags allow air to pass through extremely slowly due to their compact size, TPU plastic logos, and central gravity weight. Without adequate airflow, the impregnated activated carbon inside remains largely inactive—most air simply bounces off the surface, with only a small fraction passing through for purification. As a result, standard impregnated activated carbon offers limited capacity, effectively targeting only low-molecular-weight odors, toxic gases, and VOCs for a maximum of 2-3 months.

The Advanced Plantorigen Car Purifier features a sealed pouch containing 150 grams of a specialized mix—impregnated activated carbon, zeolites, molecular sieves, plant nanolites, electrons, and membranes(nano coating technology)—placed half-filled on the upper dashboard. As airflow passes through the pouch, it gets fully purified by the adsorbent materials. Dashboard vibrations from engine operation, road humps, and potholes naturally shuffle the mix, exposing fresh material for continuous, efficient air purification.

PlantOrigen's proprietary nano-coating technology is applied to impregnated activated carbon, natural zeolites, and molecular sieves. This innovation enhances adhesion, enabling all 40 toxic gas molecules to bind to the material surface up to 100x times more strongly than standard impregnated activated carbon, zeolites, or molecular sieves. As a result, the product maintains peak performance for up to 1.5 years.

How to Know When It's Time to Replace It

Since it's not like a filter that you can see is dirty, here are the signs it's no longer effective:

1. The "New Car Smell" Returns: If you start noticing that distinct plastic/chemical smell again after it had disappeared, it's a prime indicator the bag is saturated.
2. Increased Window Fogging: As the zeolites/molecular sieves become saturated with moisture, they lose their ability to act as a desiccant, and you might see more fog on your interior windows on cold mornings.
3. Time-Based Replacement: The simplest method is to follow the manufacturer's recommendation, which is usually 1 to 1.5 years. Mark your calendar. For a high-use car (new, driven daily in a city), replacing it annually is a very safe bet.
4. It Gains Weight: A saturated bag will be noticeably heavier than a new one because it's holding moisture and chemical compounds.
5. Manufacturer's Guideline: Most reputable brands provide an estimated lifespan (e.g., "lasts up to 1 to 1.5 years").

Can You "Recharge" It?

No need of sunlight recharge the product for better performance.Our product already having nano coating technology which enhance the product life upto 1.5 years.

Conclusion

Don't think of it in terms of a fixed expiration date. Monitor its performance. Once it stops controlling odors, it's time to recharge it.For consistent air purification, the safest and most effective practice is to replace the bag every 12 to 18 months.
