Due to their different functional characteristics, the activated carbon adsorption cabinet and the fresh air pressurization cabinet have obvious differences in their applicable scenarios, as follows:
I. Applicable Scenarios of Activated Carbon Adsorption Cabinets
The core of the activated carbon adsorption cabinet is to adsorb odors and organic pollutants in the air (such as formaldehyde, VOCs, stench, etc.) through activated carbon, focusing on the purification of existing air without the need to introduce outdoor fresh air. It is suitable for the following scenarios:
1. Places with local pollutants or odors
Newly renovated/refurbished Spaces: newly renovated residences, offices, children’s rooms, etc., can absorb harmful gases such as formaldehyde, benzene, and TVOC released by decoration materials, reducing the concentration of indoor pollutants.
Kitchen/Dining area: For family kitchens and the back kitchens of small restaurants, it can absorb the smell of cooking fumes and food residues, reducing the spread of indoor cooking fumes.
Bathroom/Pet activity area: The damp odor, pet feces, or body odor in the bathroom can be quickly improved in local air quality through activated carbon adsorption.
Laboratory/small workshop: A place involving operations of chemical reagents, inks, adhesives, etc., which can adsorb volatile harmful gases (such as acetone, toluene), protecting the health of operators.
2. Scenarios where ventilation conditions are limited but air purification is required
Sealed storage Spaces, such as wardrobes, shoe cabinets, and basement storage rooms, can reduce the unpleasant odors caused by dampness and mold, and prevent clothes and items from being contaminated.
Small office cubicles/meeting rooms: When there are many people or temporary odors (such as food or smoke smells) occur, the air is purified in a circulating manner to maintain comfort.
Inside the car: A small activated carbon adsorption device can absorb the odors and formaldehyde released by leather and plastic inside the vehicle, improving the micro-environment inside the car.
3. Scenarios where specific pollutants need to be dealt with specifically
Residences near breeding sites: Absorb ammonia, odors, and other irritating gases that drift from breeding farms.
Printing/spray painting small workshops: Handle the volatile organic waste gas during the production process to reduce the impact on the surrounding environment (needs to be used in conjunction with exhaust ventilation).
Ii. Applicable Scenarios of the Fresh Air Booster Cabinet
The core of the fresh air booster cabinet is to introduce filtered outdoor fresh air and maintain positive indoor pressure through pressurization, focusing on solving the problems of “insufficient ventilation” and “intrusion of external pollutants”. It is suitable for the following scenarios:
1. A closed space that requires a continuous supply of clean, fresh air
Residential buildings in areas with smog or poor air quality: After filtering outdoor PM2.5, pollen, and dust, they are sent into the room. At the same time, positive pressure is used to prevent unfiltered air from seeping in through the gaps of doors and Windows, protecting the elderly, children, and people with allergies.
High-rise buildings/enclosed apartments: Poor natural ventilation conditions. Fresh air is delivered to core areas such as bedrooms and living rooms through fresh air booster cabinets to reduce CO₂ concentration and prevent air turbidity.
Basement/semi-basement: Damp and poorly ventilated. Introducing dry and filtered fresh air can reduce mold and dampness, and at the same time balance the air pressure.
2. Places with requirements for air pressure and air cleanliness
Hospital consultation rooms/home care areas: It is necessary to maintain positive pressure indoors to prevent the invasion of external bacteria and protect patients or people with weakened immunity (such as those recovering from surgery).
Precision instrument storage room: such as storage rooms for photographic equipment and electronic devices, positive pressure is used to prevent dust from entering, and the air is kept clean in combination with the filtration function.
Gym/yoga studio: When people exercise, they need a large amount of fresh air. The fresh air booster cabinet can quickly replace the indoor stale air (containing sweat smell and high CO₂), improving the comfort of exercise.
3. Scenarios with dense populations and requiring efficient ventilation
In school classrooms or training institutions, when there are many students, CO₂ is prone to exceed the standard. The fresh air booster cabinet continuously replenishes fresh air to reduce the risk of pathogen transmission and ensure a healthy learning environment.
Small offices/meeting rooms: Prolonged isolation leads to stuffy air. By circulating fresh air, office efficiency can be enhanced, and “air conditioning illness” can be reduced.
Summary
Activated carbon adsorption cabinet: “internal circulation purification”, suitable for treating odors and harmful gases in existing air, mostly in local Spaces or environments with limited ventilation.
Fresh air pressurized cabinet: “External introduction + pressurized anti-pollution”, suitable for closed/sensitive scenarios where fresh air needs to be replenished, air pressure controlled, and external pollution protected.
The two can be used in combination (for example, the fresh air cabinet introduces clean air, and the activated carbon cabinet deals with residual odors in the room), but their functions are irreplaceable.
