Filtration and Purification Technologies
Legom air purifiers combine several purification stages, selected per model to target different airborne contaminants. The same core technologies are carried across the range as it grows:
| Technology | What It Targets |
|---|---|
| HEPA Filtration | Fine particulates, dust, pollen, and PM2.5 |
| Activated Carbon | Odours, smoke, and volatile organic compounds (VOCs) |
| UV-C | Bacteria, viruses, and other microorganisms |
| Negative Ion and Ion Catalytic | Freshens air and helps suspended particles settle |
| Heat Recovery (fresh air units) | Recovers heat while exchanging stale indoor air for filtered fresh air |
Car and Portable Purifiers
Compact purifiers designed for vehicles and small personal spaces, using negative ion technology to freshen the air in an enclosed cabin. Current models include the FLZ-MA-03 Car Negative Ion Purifier and the KJ20F-C01 Air Purifier for Automobile.
Home Negative Ion Purifiers
Negative ion purifiers for bedrooms and living areas, combining ionization with filtration to reduce airborne particles and refresh indoor air. A current model is the KJ200F-A01 Oxygen Source Negative Ion Purifier.
Air Conditioner Companions
Purifying units designed to work alongside a split air conditioner, adding filtration and ionization to the conditioned air. Current models include the KJF-B01, KJF-B02, and KJF-B03 Air Conditioning Companion.
Fresh Air Ventilators and Heat Exchangers
Ceiling-mounted, ducted units that supply filtered fresh air to a room or building while recovering heat from the outgoing stale air, improving indoor air quality without wasting energy. Current models include the XFDD2-500-02JP and XFDD2-400-01JP Ceiling-Mounted Fresh Air Ventilator, the XFDD3-360-01JP Full Heat Exchanger, and the XFDD3-650-01J Campus Fresh Air Ventilator.
Ion Catalytic Fresh Air Purifiers
Fresh air purifiers using ion catalytic technology to deliver continuous clean, filtered air to a space. A current model is the XFQT-60-01S Ion Catalytic Fresh Air Purifier.
The Legom air purifier range is regularly expanded with new formats and filtration configurations. The models above reflect the current lineup. Contact the Legom Technical Team for the latest models, full specifications, and airflow data to match your space and market.
How to Select the Right Air Purifier
Choosing the correct unit comes down to where it will be used, which contaminants you need to remove, and the airflow the space requires. Confirm these three points before ordering:
Where it will be used
Match the format to the space. Choose a compact car or portable purifier for a vehicle or desk, a home negative ion purifier for a bedroom or living room, an air conditioner companion for a room already served by a split AC, or a ceiling-mounted fresh air ventilator for whole-room and whole-building ventilation.
Which contaminants to remove
Decide what the air needs cleaned of. HEPA filtration captures fine particulates, dust, and pollen, activated carbon handles odours, smoke, and VOCs, UV-C targets bacteria and viruses, and negative ion or ion catalytic stages help freshen the air. Many models combine several of these stages in one unit.
Airflow and room size
Size the airflow to the room. A small cabin or desk needs only a compact unit, while a large room, classroom, or whole building needs a fresh air ventilator with the right air volume. For ventilation projects, also consider heat recovery to keep energy use down while bringing in fresh air.
Once you have these three points, the Legom engineering team can recommend the right model and configuration, or start a custom OEM project. Contact us via WhatsApp or info@legomsmart.com.

Every Legom air purifier passes a structured 7-stage process, ensuring the build quality, filtration integrity, and verified performance that B2B buyers depend on at scale.
Component Intake
Housings, motors, filters, and electronics inspected for grade and specification
Housing Assembly
Casing, ducting, and structural parts assembled and prepared for the internal modules
Filtration and Fan Module
HEPA, carbon, and fan modules fitted, with airflow paths sealed and aligned
Ionizer and UV Integration
Negative ion, ion catalytic, or UV-C modules integrated where the model specifies
Electronics and Controls

Applications
Legom air purifiers and fresh air systems are used wherever cleaner, healthier indoor air is needed, from a single car cabin to a whole building. The range covers personal, residential, commercial, and institutional spaces.
Homes and Living Spaces
Negative ion and multi-stage purifiers clean the air in bedrooms and living rooms, reducing dust, allergens, and odours for everyday comfort and healthier indoor air.
Vehicles and Personal Spaces
Compact car and portable purifiers freshen the air in vehicle cabins and at the desk, where a small unit makes a clear difference in an enclosed space.
Rooms with Air Conditioning
Air conditioner companions add filtration and ionization to rooms already served by a split AC, improving the quality of the conditioned air without a separate floor unit.
Offices and Commercial Spaces
Fresh air ventilators with heat recovery supply filtered fresh air to offices and commercial interiors, maintaining air quality while keeping energy use under control.
Schools and Campuses
Campus fresh air ventilators deliver higher-volume filtered ventilation to classrooms and shared spaces where many people share the same air.
New Build and Renovation
Ceiling-mounted ventilators and heat exchangers are designed into new builds and refurbishments where balanced fresh air supply is part of the indoor air quality plan.
Frequently Asked Questions
Legom manufactures a range of air purifiers and fresh air systems, including compact car and portable purifiers, home negative ion purifiers, air conditioner companions, ceiling-mounted fresh air ventilators with heat recovery, and ion catalytic fresh air purifiers. The range is regularly expanded with new models, and all are CE certified and produced in-house at our Jiaxing facility.
Across the range, Legom purifiers use HEPA filtration for fine particulates, activated carbon for odours, smoke, and VOCs, UV-C for bacteria and viruses, and negative ion or ion catalytic stages to freshen the air. Each model combines the stages suited to its purpose, so a car purifier and a whole-building fresh air unit use different configurations.
A HEPA filter captures very fine airborne particles, including dust, pollen, pet dander, and PM2.5. It works by trapping particles as air passes through a dense fibre mesh, which is why HEPA is the core stage for particulate removal in most air purifiers.
An air purifier recirculates and cleans the air already inside a room. A fresh air ventilator brings filtered outdoor air in and pushes stale indoor air out, often recovering heat in the process so the building does not lose energy with the exchange. Purifiers suit single rooms, while fresh air ventilators suit whole-room and whole-building ventilation.
A heat exchanger fresh air unit transfers heat between the outgoing stale air and the incoming fresh air. In winter it warms the cold incoming air using heat from the air being expelled, and in summer it does the reverse. This recovers energy that would otherwise be lost, so the building gets fresh, filtered air without a large heating or cooling penalty.
Match the airflow of the unit to the volume of the room. A small cabin or desk only needs a compact purifier, while a large room, office, or classroom needs a higher-airflow unit or a fresh air ventilator. Our technical team can recommend the right model once you share the room size and intended use.
