Celrith washable HEPA filters (cylindrical) are replacement filter elements for handheld and cordless vacuums, robot vacuums, and mattress cleaners. They capture fine dust (PM2.5), dust mites, pollen, and hair from the airstream, preventing exhaust re-contamination. Designed for device manufacturers and aftermarket brands, these filters combine PTFE membrane media with low airflow resistance to protect suction and motor life.
Every vacuum cleaner releases air back into the room. Without effective filtration, fine particles—PM2.5, dust mite debris, pollen, and hair fragments—escape through the exhaust and resettle on surfaces. Over time, this secondary contamination undermines the cleaning effort and can affect indoor air quality.
Celrith filters are built around high-precision microporous media that trap these contaminants at the source: inside the dust cup. The result is cleaner exhaust air and fewer particles recirculating in the breathing zone.
Clogged or inefficient filters increase airflow resistance, forcing the motor to work harder and draw more power. This can reduce suction, shorten battery runtime, and raise motor temperature. In handheld vacuums, where space and weight are limited, the filter’s pressure drop directly affects cleaning performance and user experience.
Additionally, disposable filters add to waste and operating cost. A washable filter that maintains low resistance after cleaning relieves both the equipment load and the maintenance burden.
Celrith’s cylindrical HEPA filters use a PTFE membrane laminated to PP melt-blown layers, optionally with antibacterial treatment. The pleated design provides high dust holding capacity while keeping airflow resistance low. This helps maintain strong suction and prevents motor overheating, supporting longer battery life per charge.
The filter is washable: after rinsing and thorough drying, it can be reused multiple times (typically 20–30 wash cycles with proper care), reducing waste and replacement frequency. The outer frame is injection-molded from environmentally friendly plastics and can be fitted with a rubber sealing ring to ensure a tight, leak-free fit in the dust cup. Celrith offers 100% custom manufacturing based on your device’s air path and dust cup dimensions, including diameter, height, pleat count, end-cap structure, and seal material. With over 20 years of filter development and more than 1,000 filtration solutions, Celrith can adapt to your specific model.

Celrith cylindrical HEPA filters are used by manufacturers of handheld and cordless vacuums, robot vacuum brands, and aftermarket filter suppliers. They are also specified for mattress cleaners, wet-dry floor cleaners, and car vacuum producers. If your device requires a compact, high-efficiency filter that balances suction, battery life, and maintenance, this product is designed for you.
Celrith products comply with REACH and RoHS environmental regulations, and we can provide compliance documentation. Our quality and environmental management systems are certified to ISO 14001 and ISO 45001, and our IATF 16949 automotive quality certification (obtained in 2024) reflects our commitment to rigorous process control.
Our in-house CNAS-accredited laboratory verifies filtration efficiency, dust holding capacity, and airflow resistance, ensuring batch-to-batch consistency. Manufacturing takes place in a 50,000 m² plant, which includes 20,000 m² of cleanrooms across six workshops, protecting filter media from secondary contamination. With over 20 years of export experience to Europe, the US, Japan, and South Korea, we support OEM/ODM projects from concept to delivery.

Celrith cylindrical HEPA filters capture fine particles (PM2.5), dust mites, pollen, and hair from the dust cup. They prevent these contaminants from being re-released into the exhaust air, reducing secondary pollution in the room.
Our washable HEPA filters achieve H11–H13 efficiency (≥95%–99.95% for 0.3 μm particles), customizable to your needs. With proper cleaning and complete drying, they typically withstand 20–30 wash cycles with limited performance degradation. All data is verified by our CNAS-accredited laboratory.
Yes. We offer full OEM/ODM customization, including diameter, height, pleat count, end-cap structure, and seal material. Provide a sample, drawing, or target dimensions, and we will adapt the design to your device’s air path and dust cup.
We provide free samples for standard specifications; you only cover international shipping. Custom samples incur a fee based on tooling complexity, refundable upon mass production. Quotations are tailored to your specifications and quantity.
Standard models have an MOQ of 3,000 pieces. Custom tooling typically requires 5,000 pieces, depending on specifications. Lead time is 25–35 days after order confirmation; peak seasons may require earlier scheduling.
With regular washing (every 2–4 weeks depending on use), the filter can last 20–30 wash cycles. Replace it when suction noticeably drops or the filter shows damage or persistent odor. Following your device manufacturer’s recommendations is also advised.
The high-porosity design minimizes pressure drop, reducing motor load and heat. This helps maintain strong suction and can extend battery runtime per charge, especially in cordless handheld vacuums.
