PRIMARY FILTER

The Castus Washable Primary Filter is the first line of defense against airborne pollutants, capturing larger particles like dust, pet dander, and hair before they reach the deeper filtration layers. Designed for durability and reusability, this filter never needs to be replaced—simply wash and reuse to maintain optimal airflow and extend the life of the other filters. With low maintenance and high efficiency, it ensures cleaner air with minimal upkeep.

ACTIVATED CARBON FILTER

The Activated Carbon Filter is specially designed to absorb and neutralize odors, gases, and harmful chemicals, ensuring fresher, cleaner air. It effectively removes volatile organic compounds (VOCs) from cleaning products, paints, and furniture, as well as unwanted smells from smoke, cooking, and industrial sources. By trapping airborne pollutants at a molecular level, this filter helps create a healthier and more comfortable indoor environment.

NANO COPPER FILTER

The Nano Copper Filter enhances air quality by harnessing the natural properties of copper. Copper ions interact with microscopic particles in the air, disrupting their structure and preventing them from persisting or multiplying. This advanced filtration layer minimizes buildup within the system, supporting long-term performance and delivering cleaner, fresher air with every breath.

PHOTOCATALYST FILTER

The Photocatalyst Filter uses light-activated titanium dioxide (TiOâ‚‚) technology to break down and neutralize harmful airborne pollutants, volatile organic compounds (VOCs), and odors. When exposed to light, the photocatalytic reaction helps decompose chemical contaminants into harmless byproducts, improving overall air quality. This advanced filtration layer enhances the effectiveness of the purification system, ensuring a cleaner, fresher indoor environment free from harmful gases and pollutants.

HEPA 13 FILTER

The HEPA 13 filter is a filtration system that captures 99.95% of airborne particles as small as 0.1 microns, including dust, pollen, mold spores, and fine pollutants. Its high-efficiency performance helps reduce airborne allergens and irritants, improving overall air quality. Designed for long-lasting reliability, this advanced filter ensures cleaner, fresher air in any environment.

NANO SILVER FILTER

The Nano Silver Filter uses advanced silver ion technology to target and break down unwanted airborne particles at the molecular level. Silver ions interact with pollutants, disrupting their integrity and preventing them from persisting in the air. This powerful filtration layer strengthens the overall purification process, adding an extra level of defense against airborne contaminants and supporting cleaner, safer indoor air.

OUR COMMITMENT TO SUSTAINABILITY

At Castus, we believe that clean air shouldn’t come at the cost of a polluted planet. That’s why we are dedicated to sustainable air purification solutions that minimize environmental impact while delivering exceptional performance.
 

To reduce waste and resource consumption, we have combined multiple filtration technologies into fewer, more efficient filters, ensuring maximum air purification with a lower environmental footprint. The Nano-Photocatalyst and Nano-Crystal Activated Carbon filters have been merged into a single high-performance filter, effectively removing VOCs, odors, and chemical pollutants. Additionally, the HEPA 13, Nano Copper, and Nano Silver filters have been combined into one, ensuring comprehensive particle filtration, bacterial defense, and virus elimination in a more eco-friendly design.
 

By optimizing filter efficiency and reducing waste, we make sustainable air purification a reality— helping you breathe easier while protecting the environment.
