Kaltech's KL-W01U is a wall mounted air purifier. Kaltech's proprietary photocatalyst technology decomposes harmful organic substances, allergens, smoke, VOCs & odors (including toxic nail salon odors like toluene, acrylic & acetone).

Designed to target particles as small as 0.0001 microns (0.1nm) — such as odor molecules, VOCs, and microscopic allergens that conventional filters may miss. Unlike typical air purifiers that trap particles, this system utilizes advanced photocatalyst technology that helps decompose harmful substances at the molecular level. Effectiveness tested by University of Tokyo, Nihon University and Riken Laboratory in Japan.

The noiseless design matches varieties of occasion and space. For the wall installation, screw or pin down to the wall and wire the adaptor and cable. This model has an odor sensor and four switching modes, high /low /silent / auto, suitable for your environment and adapts into various spaces.

Kaltech is not HEPA-based and does not use UV, ozone, or ionization technology. It utilizes proprietary Japanese photocatalyst technology, activated by a 410nm visible light LED. Our technology ensures effective air purification without generating harmful radiation. Easy maintenance. Take out the filter and soak into water once a few months. No filter replacement is required.

• JAPANESE LED PHOTOCATALYST TECHNOLOGY - Unlike traditional air purifiers that only trap particles, Kaltech’s LED photocatalyst actively decomposes harmful organic substances—including VOCs, smoke, odors, and pet allergens—at the molecular level. Tested for effectiveness by the University of Tokyo, Nihon University, and RIKEN Laboratory in Japan.
• DESIGNED TO TARGET PARTICLES AS SMALL AS 0.0001 MICRONS (0.1nm) - Such as odor molecules, VOCs, and microscopic allergens that conventional filters may miss. Unlike typical air purifiers that trap particles, this system utilizes advanced photocatalyst technology that helps reduce harmful substances at the molecular level.
• WASHABLE REUSABLE FILTERS - Save time and money with washable, reusable filters. Features a dual-filter system: a photocatalyst filter and a pollen/dust filter for long-term, eco-friendly performance.
• HELPS IMPROVE AIR CONDITIONS THAT MAY CONTRIBUTE TO MOLD - Tested on airborne Staphylococcus aureus by the Kitasato Environmental Science Center in Japan, this product uses photocatalyst technology to reduce airborne organic matter in enclosed spaces. (Note: This product does not remove visible / surface mold. Please clean mold first, then place Kaltech Wall Air near the mold-prone area) **This is not a medical device. Mold-related results are based on in-house and controlled-environment testing**
• NO HEPA, NO UV, NO OZONE – JUST ADVANCED JAPANESE TECHNOLOGY - Kaltech does not use HEPA filters, UV light, ozone, or ionization. Instead, it utilizes a proprietary Japanese photocatalyst technology activated by a 410nm visible light LED—providing a safer, more innovative solution for improving indoor air quality around pets and people.
• ODOR SENSOR & AUTO MODE - DESIGNED FOR 24/7 CONTINUOUS USE - This product does not include an automatic shut-off function. It is designed for continuous 24/7 operation. For noticeable odors, switch to High mode and run for several hours.
• AIR PURIFIER FOR ALLLERGENS, SMOKE, MOLD, ODORS, POLLEN & PET ALLERGIES, VOC & DUST - Effectively targets airborne allergens, mold, smoke, pollen, VOCs, fine dust particles, and odors—including chemical odors often found in nail salons, such as toluene, acrylic, and acetone. Suitable for both people and pets.
• ULTRA QUIET OPERATION FOR PEACEFUL ENVIRONMENTS - Runs as low as 20 dB, Silent on low and quieter than a whisper. Even at full power, it stays under 44 dB to ensure minimal disruption in bedrooms, nurseries, or quiet workspaces.
