Frequently Asked Questions

A: Air‑only ozone machines lack supporting air pump and water‑dissolving design. For water disinfection, select LUFUTATECH dedicated water‑treatment ozone units such as LFT‑150WT, which is equipped with built‑in air pump for better water mixing performance. air ozone machine uses ozone tube to generate ozone. However, air ozone generator usually uses ozone plate instead. This is main difference.

A: 10‑20 minutes soaking is recommended for fruits and vegetables. After ozone treatment, rinse food with clean tap water before eating. LUFUTATECH LFT-150QB has 4 working modes, select proper mode, very simple. For Meat mode 15 minutes working STER mode 25 minutes working For Purify mode 20 minutes working For Vegetable and Fruit mode 10 minutes working

A: Our portable ozone machines are designed for food cleaning and general‑purpose water disinfection. They are not intended for continuous direct drinking‑water production. LUFUTATECH item LFT‑150WV can sterilize water inside containers as pre‑treatment. Please allow sufficient aeration time before drinking treated water.

A: Yes, LUFUTATECH, as original manufacturer, provides OEM & ODM service for water‑treatment ozone generators, including custom ozone output, voltage and logo for global distributors.

A: LUFUTATECH Standard units carry CE certificate. UL / ETL / PSE certification can be arranged upon request for North America, EU and Japanese markets.

A: Common air‑purification technologies include HEPA filtration, activated carbon adsorption, UV‑C germicidal light, negative‑ion generator, plasma and ozone oxidation, electrostatic, PCO, RCI CELL technology. Each technology has its own advantages and applicable limits. LUFUTATECH develops products covering multiple purification technologies for different application demands.

A: HEPA filter physically traps fine particles such as dust, pollen, pet dander and mold spores. It is excellent for removing solid particulates, but cannot eliminate gaseous odors, VOCs or kill airborne viruses by itself. Some LUFUTATECH dehumidifier‑purifier models are fitted with standard HEPA filter modules including H10 and H13.

A: Activated carbon absorbs gaseous odors and VOCs via physical adsorption. It cannot kill bacteria or viruses. Carbon will saturate over time and must be replaced regularly; high‑concentration heavy odors will shorten its service life dramatically.

A: UV‑C light damages the DNA of bacteria and viruses to achieve disinfection. However, UV‑C only works when pathogens pass directly through the light beam; it cannot penetrate corners or eliminate stubborn odors. It is usually used as auxiliary purification function instead of standalone solution. On the contrary Ozone can reach anywhere that UVC can't reach. And if the object is too far away from the UVC, there is almost no function.

A: Negative ions make suspended particles stick together and drop onto surfaces. It reduces floating dust, yet it does not destroy odors, VOC or microorganisms. Settled pollutants may re‑enter the air again when disturbed. Many of LUFUTATECH air purifier such as LFT-223AC with negative ion output ≥5×10⁶ ions/cm³.

A: Unlike filters which trap or absorb contaminants, ozone oxidizes and decomposes odors, mold, bacteria, viruses and VOCs at molecular level. As a gas, ozone can reach cracks and hidden corners that filters cannot access. Important note: ozone shock treatment must run in unoccupied space. LUFUTATECH portable ozonators such as LFT‑150LB and LFT‑153LK adopt ceramic‑plate corona‑discharge ozone technology.

A: HEPA, carbon filter, UV‑C and ionizers can only relieve such heavy odors partially. For embedded heavy‑duty odors, ozone oxidation is the most effective solution. For fire restoration and heavy commercial odor removal, we recommend LUFUTATECH LFT‑153LK 10G/H commercial ozonator. lufutatech also has larger ozone output industrial ozone machine such as LFT-154 20G/H, LFT-144AS heavy duty ozone machine with 40G/H ozone output.

A: Yes. Many real‑world projects combine different technologies. For example: use HEPA + carbon for daily occupied‑space filtration; run ozone generator for periodic shock‑treatment when the room is empty. LUFUTATECH can provide multi‑function combined‑unit solutions via OEM customization. Most of LUFUTATEH air purifiers use multi-purification tech e.g. LFT-263, LFT-262. LFT-221AB. Only ozone is the best way to deeply clean and remove odor. Caution, if ozone works, human, pet should be away and the place should be closed well. Air at least 30 minutes before you come in after ozone treatment.

A: True HEPA means the filter meets standard of removing ≥99.97% of 0.3μm airborne particles. HEPA grades H10‑H13 follow EN 1822 European standard. H10: basic HEPA grade, around 85% efficiency for 0.3μm particles H13: high‑grade True HEPA, captures ≥99.95% of 0.3μm fine particles, widely used for commercial‑grade air cleaning. Many LUFUTATECH multi‑function air purifiers adopt H13 True HEPA for high‑efficiency particulate filtration. Please note even H13 HEPA only captures solid particles; it cannot break down VOC gas or stubborn odors.

A: Yes. As original manufacturer, we support OEM & ODM. You can configure combinations of HEPA filter, activated carbon, ozone module according to your target market and application scenarios.

A: MOQ varies by product type. For standard off‑the‑shelf items, our regular MOQ is low for sample orders. For OEM & ODM custom orders (custom logo, packaging, voltage, parameters), MOQ 200PCS. Please contact our sales team for exact MOQ quotation for your target models.

A: We support T/T (Telegraphic Transfer) as main payment term. For bulk orders, we usually require 40% deposit and 60% balance before shipment. For small trial order, we require 100% T/T before shipment. the terms such as L/C are negotiable for large‑volume long‑term cooperation. All payments should be made to our official company account.

A: For ready‑stock standard units: 3‑7 working days after receiving deposit. For OEM/ODM customized orders: lead time is 30-45 working days, depending on customization complexity and order quantity. We will provide estimated schedule upon your inquiry.

A: Yes. As original manufacturer, LUFUTATECH provides full OEM & ODM solutions. Customizable items include brand logo printing, custom packaging, power voltage, plug type, ozone output parameter adjustment and user manual modification. We support private‑label for global distributors and Amazon sellers. LUFUTATECH has in-house R&D team with average experience of 15 years in air purification industry.

A: We support multiple shipping methods: sea freight (FCL/LCL), air freight, express courier. We can arrange door‑to‑door DDP delivery for specified destinations. Customer can also use your own nominated forwarder. Shipping cost and transit time depend on destination port and order volume.
