Engineered for Maximum Air Purification

The LUFTQI LUFT Mask is a personal, USB-powered air purifier featuring a patented triple-vortex airflow system that maximizes air circulation and filtration efficiency. It integrates three proprietary purification technologies developed by LUFTQI to deliver up to 99.9% purification and decomposition performance:

Electrostatic ion dust collection: Powered by LUFTQI’s second-generation ionization technology and a 5,000V high-voltage field, it boosts dust capture performance by 300%, efficiently removing fine particles, allergens, and airborne pathogens.

Photocatalytic purification: Utilizing LUFTQI’s third-generation SPP photocatalyst, it releases hydroxyl radicals and superoxide ions to break down odors and viral structures, improving purification efficiency by 200%.

UV light sterilization: A continuous UV light source ensures that trapped bacteria and mold spores are fully neutralized and unable to regrow.

Smoke Test: Electrostatic Purification with Triple Vortex Airflow

The LUFT Mask’s first stage of purification features LUFTQI’s second-generation electrostatic ion dust collection system, powered by a 5,000V high-voltage electric field — a level typically found in industrial-grade purifiers. This intense electrostatic force actively attracts and traps airborne pollutants such as dust, smoke, and microbes, all without using traditional filters. Both larger particles like PM10 and finer PM2.5 respond effectively to electrostatic attraction: PM10 is more easily charged and captured due to its size, while ultrafine PM2.5, often harder to filter, is efficiently drawn to the inner metal tube under high-voltage ionization.

To enhance this process, LUFT integrates its patented triple-vortex airflow design, accelerating air intake and increasing particle contact time within a compact form. This aerodynamic breakthrough enables LUFT to achieve the world’s smallest electrostatic dust collection system — powerful, portable, and proven.

In a controlled smoke-chamber test, the LUFT Mask cleared all visible smoke in just 54 seconds. It’s a clear result that speaks for itself — fast, effective, and filter-free.

SPP 3rd Gen Photocatalytic Nanotech for Decompose and Neutralize: Ozone Free Purifying Process

The LUFT Mask’s second stage of purification is powered by LUFTQI’s patented third-generation SPP™ photocatalytic nanotechnology, designed to break down formaldehyde, VOCs, odors, viruses, and other harmful substances at the molecular level — far beyond the reach of HEPA filters. At the core is a 5-nanometer titanium dioxide (TiO₂) catalyst, embedded into a porous honeycomb ceramic structure and sintered to form a highly crystalline and stable photocatalytic surface. While many products use micron-scale photocatalysts with limited effectiveness, LUFT’s 5nm particles sit squarely in the scientifically proven 5–10nm sweet spot for peak performance.

Photocatalysts do not degrade over time. Triggered only by light, LUFT’s system enables continuous, filter-free operation. Its UV LED is precisely tuned to deliver the ideal wavelength and intensity, ensuring the TiO₂ surface receives sufficient energy for stable, long-term purification — all without producing ozone or other harmful byproducts.

To validate its effectiveness, LUFT conducted a real-world experiment using two identical plant environments exposed to formaldehyde-rich paint fumes. Formaldehyde and VOCs are not only carcinogenic to humans, but also inhibit plant growth. After four days, the LUFT-protected plants appeared noticeably healthier and stronger, demonstrating the system’s ability to neutralize toxins and safeguard living environments.

Sealed UV Light Purification: Disrupts Organic Threats at the Core

The LUFT Mask’s third stage of purification utilizes continuous UV light exposure to destroy the internal structure of harmful microorganisms such as bacteria, mold, and viruses. Unlike surface-level sterilization, this built-in UV technology penetrates deep into cell membranes, effectively reducing their activity or eliminating them completely — all while remaining fully sealed inside the unit to ensure zero light leakage and no ozone emissions.

As viruses constantly mutate, an effective method to stay protected is to both block airborne droplets and actively destroy the viral and bacterial structures. LUFT’s UV purification stage addresses this by neutralizing microbial threats at the molecular level, making it a powerful layer of defense against evolving strains.

To validate its effectiveness, LUFT conducted a mold-resistance experiment using perishable food. Two identical sandwiches were placed in closed containers — one with a LUFT Mask purifying the air, and the other without. After six days, the sandwich in the LUFT-treated container showed no visible signs of mold, while the untreated control had clear fungal growth. This demonstrates LUFT’s ability to inhibit microbial reproduction and maintain cleaner, safer environments.

Verified by 3rd-Party Laboratories

The LUFT Mask’s purification performance has been validated through multiple independent tests. According to SGS test reports, it achieves:

PM2.5 reduction > 99.9%

Formaldehyde reduction > 99.0%

Nicotine reduction > 78.6%

Ozone (O₃) output measured at only 0.003 PPM, well within safety limits and confirming virtually zero ozone emission.

These results demonstrate LUFT Mask’s ability to effectively remove airborne pollutants and chemical compounds commonly found in everyday environments.

Additionally, noise level assessments were carried out by Bell Acoustics (PAL noise test reports), ensuring that the LUFT Mask operates quietly and comfortably for daily wear.

Certified with CE and FCC, the LUFT Mask stands as a reliable personal air purifier tested for both safety and real-world effectiveness.

USB Powered with Smart AQI Sensing, CO₂ Alert, Fan Speed Control, Night Mode, and Washable Dust Cup

Equipped with an AQI sensor compliant with Germany’s UBA standards, LUFT Mask automatically detects air quality and adjusts fan speed accordingly. When higher pollution levels are detected, purification performance is increased to maintain a healthy environment. You can also manually adjust fan speed with one, two, or three taps — switching between low, medium, and high. It's intuitive and gives you full control when needed.

A real-time CO₂ alert notifies you when indoor carbon dioxide levels are too high, reminding you to open a window or door to improve ventilation. For sleep environments, Night Mode turns off all indicator lights with a long press, while continuing to purify the air silently in the background.

LUFT Mask is USB-powered, making it ideal for use with laptops, power banks, or car USB port — no bulky adapters or disposable batteries needed. It’s low-maintenance and eco-friendly, with a reusable metal dust cup that can be rinsed clean with water. No filters to replace, no extra waste, no recurring cost.

There are so many small air purifiers, what's special about LUFT?
Over 90% of small air purifiers on the market are of the negative ion type. They are popular due to their compact size and cost-effectiveness. However, their effectiveness in truly purifying the air has been a topic of debate. The main principle behind negative ion air purifiers is that they release a stream of negative ions into the air, which then bond with positively charged particles such as dust, pollen, smoke, and other allergens, forming larger particles.

While this process sounds promising, it has a significant drawback. The negative ion purifiers do not eliminate these larger particles; instead, they fall onto the surfaces around the purifier, such as walls, ceilings, and furniture, due to their increased weight. This phenomenon is often referred to as the "Black Wall Effect".

While the air may appear cleaner because these particles are no longer suspended in it, they are still present in the environment and can be stirred back into the air with any disturbance, like walking by or turning on a fan. This process could potentially lead to secondary pollution.

Since the range of negative ion emission is limited, most of them cover only about 20 cm around the device. As a result, you'll notice a lot of dust accumulation around the device. These fallen particles create a layer of dust around the device, requiring regular cleaning of the surrounding areas. Hence, negative ion purifiers are not truly cleaning the air but merely displacing particles.

In contrast, LUFTQI utilizes Photocatalytic Oxidation to provide genuine air purification, capturing and neutralizing harmful particles in the air. With the Duo model, LUFTQI further utilizes the bonding characteristics of negative ions to create an excellent dust collection design. Through the use of an intake fan, the dust is concentrated and properly contained within the machine itself.

Building on this foundation, the newly released LUFT Mask incorporates the second-generation electrostatic ion dust collection system, which actively attracts and traps fine particles inside a dedicated dust cup—preventing them from settling on walls or circulating back into the air like typical ionizers.
How to prove that the product is effective against pathogens, germs, molds and even viruses?
Since the advent of photocatalytic technology, it has been widely used in the air conditioning of medical environments as a sterilization method.

LUFTQI was the first to miniaturize this photocatalytic purification technology into a compact air purifier. From the early stages of product development, LUFTQI has invested substantial resources in verifying its efficacy through third-party laboratories such as SGS and SuperLab.

To address the coronavirus responsible for the global pandemic, LUFTQI commissioned a leading domestic virologist specializing in bat coronaviruses to test the effectiveness of its SPP Nanotech technology. Due to biosafety regulations, feline coronavirus was used as a test proxy. Given the structural similarities among coronaviruses, the results are considered a valid representation of viral inactivation performance.

The LUFTQI team also partnered with the Industrial Technology Research Institute (ITRI) in Taiwan to conduct field testing in a hospital bronchoscopy room, confirming the device’s ability to eliminate various bacterial strains and odors in real-world clinical environments.

In 2021, the LUFT Duo was awarded the SNQ (Symbol of National Quality) certification for epidemic prevention products, underscoring LUFTQI’s technological credibility.

In addition to the Duo model, the latest LUFT Mask has also undergone extensive third-party testing to validate its effectiveness against pathogens, bacteria, and viruses. According to SGS reports, LUFT Mask achieved:
99.9% removal of PM2.5
99% formaldehyde reduction
78.6% nicotine reduction
>99.99% elimination of bacteria, including Staphylococcus aureus, Escherichia coli, and Streptococcus pneumoniae
>99.99% inactivation of feline coronavirus, serving as a biosafety-compliant model for human coronavirus
Additionally, LUFT Mask emits extremely low levels of ozone—only 0.003ppm, far below internationally accepted safety thresholds.

Compared to its predecessors, LUFT Mask shows notable improvements in PM2.5 removal (99.9%, compared to 80.3% in Duo and 65.9% in Cube), and extends protection across a broader spectrum of pathogens. However, both the Duo and Cube remain excellent choices for room-scale air purification, offering powerful performance, compact size, and filter-free operation trusted by thousands of users worldwide.
Does LUFT Mask emit UV light externally? Is it safe for close-range or personal use?
No, LUFT Mask does not leak any UV light. The UV LEDs are fully enclosed within the internal structure of the device, and the design ensures complete light sealing. During operation, no ultraviolet rays are emitted outside the device, making it entirely safe for close-range and facial use.
What is the lifespan of LUFT air purifiers?
Theoretically, photocatalysts do not degrade over time. However, in real-world applications, their effectiveness can gradually diminish due to the accumulation of airborne dust particles that settle on the photocatalytic surface, blocking its exposure to light and reducing its efficiency.

LUFTQI has addressed this challenge through careful system optimization and design improvements. The photocatalyst in LUFT products remains protected and functional thanks to airflow engineering that helps reduce particle buildup. In fact, the main limiting factor for product lifespan is not the photocatalyst itself, but the continuously rotating magnetic levitation fan. This fan is designed with a Mean Time Between Failures (MTBF) of approximately 40,000 hours—equivalent to 3 to 5 years of continuous 24/7 use.

How often do you need to clean the metal filter? Is it true that no consumables needed?
Yes, LUFT air purifiers are designed to be eco-friendly and completely consumable-free—saving you money and reducing waste year after year. All LUFT models use stainless steel components as the first layer of dust and particle collection. LUFT Cube and LUFT Duo feature a stainless steel antibacterial mesh filter, while LUFT Mask uses a stainless steel dust collection tube. Depending on the air quality in your environment, cleaning is only needed every one to three months. Simply remove the metal part and rinse it with water.

Note: Do not rinse the main device directly with water.
Why is LUFT helpful for allergies?
Allergy symptoms result from an overreaction by the human immune system to foreign environmental substances. Diluting the allergens that cause immune responses usually improves allergy symptoms.

LUFT uses the hydroxyl radicals and superoxide ions derived from the energy conversion of photocatalysts to break and degrade organic substances. For individuals sensitive to air quality, LUFT continuously degrades allergens in the air in areas where you spend a lot of time (such as sleeping areas, offices, cars, etc.). Delivering the purified air close to the respiratory system help people who suffer from allergies.

LUFTQI team has further cooperated with the laboratory of the Department of Biotechnology at Chung Yuan Christian University to conduct animal experiments to confirm: LUFTQI's experimental group improved the research results of asthma induced by 40% of allergens.
Does LUFT need batteries to run?
Many people feel that small air purifiers should come with batteries. To clarify, none of the LUFT series include a battery and requires no charging. Therefore, when using LUFT air purifiers, you must plug them into an external USB power source (recommend 5V/2A or above) to keep them running. If you need to carry the air purifiers out, you can get portable power banks and use them together.
What kinds of odors can it handle?
Among various purification technologies, photocatalytic tech stands out for odor removal. LUFTQI's patented SPP Nanotech enables noticeable odor removal, which has been highly praised. If you have food smells, cigarette smoke, musty smells, cooking fumes, pet odors, etc., lingering in the space, LUFT can handle all of them.

We all have noses that are more sensitive than sensors. Run LUFT air purifiers in places with a strong smell, such as in a car, bathroom, or bedroom with stagnant air that has a musty or smoky smell for ten minutes, you will clearly feel the improvement of air quality.
What sizes of spaces are LUFT air purifiers suitable for?
If you intend to use LUFTQI air purifiers for personal protection, LUFTQI is not restricted by space sizes. The LUFTQI product series was developed with the design concept of purifying the breathing environment around you. At close range, through the action of directional air guides, the purified air in the nose and mouth respiratory space is 15 times greater than that of large remote purifiers.

Please refer to the data below and select based on your intended space size and type (such as car interior, desk area, bedside, personal seating area, small room, bathroom, closet, pet space, living room, dining room, meeting room, office, open kitchen, bedroom, etc.):
Product Model | Recommended Coverage Area | Application Examples
LUFT Cube | Approx. 10m2 / ~ 100 ft2
LUFT Duo | Approx. 20m2 / ~ 200 ft2
LUFT Mask | Approx. 27m2 / 260 ft2

For larger spaces, it is recommended to use multiple LUFT air purifiers to get optimal results.
