Innovative Tech and Design

Zenwell's technology sets new standards in humidification, purification, and ice making. All products are made in Korea and designed to be easy to maintain and integrate beautiful in your living space.


Natural Evaporation

Zenwell’s humidifiers are some of the few that protect your sensitive respiratory system. Our 3rd generation natural evaporation technology outputs pure water vapor at 0.2nm in width. Because of the small output size, only H20 is vaporized and any impurities in the original water itself are left behind in the water filter. In contrast, ultrasonic humidifiers emit germs and foreign substances together with the water vapor.

When we developed our washable fiber filter, we sought to solve the problem of humidifier filters being high maintenance and costly. At the time, only two types of humidification filters existed on the market: fabric filters and plastic disc filters. Plastic disc filters require tedious cleaning—the customer must disassemble and clean each of the 20 to 30 discs. Fabric filters have high replacement costs since they normally aren’t cleanable. Seeing this, we developed a humidifying filter with a 6-layer honeycomb porous structure that can be cleaned by washing with general-purpose detergent. Furthermore, unlike ultrasonic humidifiers which need to be cleaned daily because they would also output bacteria remaining in the water, Zenwell’s filter only needs to be washed twice a week because the natural evaporation process only outputs pure water vapor.

Our products are built with large capacity humidification and high humidity output. Our humidifiers come with tanks that can hold up to 4000ml, while competitors only provide 500ml tanks. With a Zenwell humidifier, one refill can run for 10 hours on average. The hourly humidity output of our strongest humidifiers is 700ml, which is 4 times higher than some competing products.

Additionally, because the natural evaporation technology creates much smaller water vapor particles, the properly humidified air can spread throughout the room. Competing products that output large water droplet would simply make the surrounding wet and leave the customer with the same dry air elsewhere in their space. Zenwell humidifiers will safely, efficiently, and easily provide perfectly humidified air that will promote healthy skin and respiratory systems.

Nano Filtration

Ultra-fine dust consists of particles under 100nm in width. Zenwell’s nano air cleaning filter blocks particles up to 0.7nm and has successfully passed emissions tests for seven harmful substances: titanium dioxide, silicon dioxide, copper and its compounds, zinc oxide, lunar caustic, zinc parathion, and octadecyldimethyl. The patented two-layer structure of the nano air filter creates a physical filtration method where the thickness and density of the filter fiber consists of air gaps smaller than fine dust, making it physically impervious to the dust.

Unlike the electrostatic filters of competing brands, Zenwell’s filters do not lose their effectiveness even on humid days. Electrostatic filters fail when the air is filled with water vapor because the water molecules the dust-attracting electrostatic charge to dissipate. Zenwell’s nano air purifying filter is developed with original technology of the Institute of Science and Technology and has pores that are physically smaller than ultra-fine dust, creating consistent performance regardless of humidity or temperature.

This technology effectively and consistently blocks viruses, bacteria, and fine dust, qualifying it for CA certification. CA certification is an official Korean certification system created to provide reliable air purifiers to consumers. This certification is granted only to products that pass strict screening standards, and quality control is continuously performed after the initial certification.

Along with basic filtering of 1nm dust, our smaller and portable Baby Safe Air Doctor purifiers utilize 293,291 UV sterilization lightning strikes per second to kill 99.9% of bacteria and viruses by attacking their DNA and RNA directly. While our larger appliances can maintain the air quality of entire rooms, the portable purifier just as effectively purifiers the space around you, no matter where you are.


Durable Crystal Ice

Zenwell’s ice maker quickly and safely creates two different types of ice cubes: quick, regular ice and slow-melt, crystal clear ice. Our ice makers produce regular ice cubes at a rate of 10 cubes every 7 minutes and crystal-clear ice at a rate of 10 cubes every 15 minutes.

The transparent and durable crystal ice employs patented technology that removes bubbles in the water, resulting in transparent ice that is sturdier and melts slower. The reason why ice from regular ice makers appears cloudy is due to the presence of bubbles in the water, which accelerates melting.

Because safety is our first consideration, we’ve included a UV lamp for sterilization in our ice makers. The deep ultraviolet (UV-C) light emitted by the lamp operates within the wavelength range of 100-280nm. This UV-C light is harmless to the human body and provides a high sterilizing power, killing or deactivating harmful bacteria and other microorganisms in the water. It is a safe form of ultraviolet radiation that does not cause skin cancer even with repeated exposure.


100% Made in Korea with Quality Materials

Zenwell products, which are 100% developed and manufactured in Korea by Koreans, prove to be meticulous and sturdy nearing perfection. Materials are chosen to last—like stainless steel screws that are safe and rust-free. Our factories employ state-of-the-art automation to manufacture consistent and high-quality appliances. The jobs that machines cannot perform well are monitored and completed by human hands. Zenwell will always strive to make the best quality products.


Long-lasting Filters & Low Energy Costs

Our humidifiers, air purifiers, and ice maker are all designed to consume low amounts of electricity. This not only makes them more environmentally-friendly, but also keeps electricity costs low. With just 3 or 4 dollars per month, you can bring cleaner air and pure ice to your household.

Zenwell is committed to increasing longevity and performance of our air purifier filters. Competing air purifiers that use conventional electrostatic filters become electrostatic as the usage time increases, so the ultra-fine dust filtering performance deteriorates and the filter life is shortened. However, the Zenwell nano air cleaning filter uses a physical filtration method that maintains much longer-lasting performance. Developed with the original technology of the Institute of Science and Technology in Korea, our nano filter has pores smaller than fine dust itself, proven to reliably capture dust even as usage time increases.

We also solved the problem of humidifiers being difficult to maintain and keep clean. Competing humidifiers with 20 to 30 disc-type filters are inconvenient even when they have an automatic filter cleaning function. The reason why Zenwell is called the cleanest humidifier in the world is because its filter can be easily washed. The fiber filter can simply be washed with laundry detergent by hand or with a washing machine separately in the normal course. This ensures that the filter doesn’t foster bacteria or mold growth, keeping the expelled water vapor as clean as possible.
