Celrith washable vacuum cleaner filters (disc shape) capture fine dust, PM2.5, allergens and pet dander before they can be exhausted back into the room, protecting both indoor air and the vacuum's motor. Made with PTFE membrane or composite PP media in a low-resistance design, they maintain strong suction and are fully washable. They are designed for handheld vacuums, robot vacuums, mite removers, wet-dry cleaners and compact car vacuums, and can be customised to fit specific models.
Every time a vacuum runs, it pulls in more than visible dirt. Fine particulate matter (PM2.5), micro-dust, dust mite allergens, pollen and pet dander are small enough to pass through basic filters and become airborne again through the exhaust. In a closed room, that recirculation can leave the air cleaner-looking but still loaded with the same allergens that triggered the cleaning in the first place. For allergy sufferers and pet owners, the filter is the line between collecting contaminants and redistributing them.
The problem compounds because many standard filters lose efficiency as they load. Once the pores clog, airflow drops, motor temperature rises and suction falls away — so the user cleans longer, uses more battery, and still leaves fine dust behind. Celrith disc filters are built around the opposite idea: high-efficiency capture at the filter face, so the contaminants stay in the bin and out of the exhaust stream.
Contaminants do not just affect air quality; they load the whole vacuum system. Dust that reaches the motor area increases the thermal burden, and a clogged filter forces the motor to work harder for the same suction. Over time, that extra load shortens motor life, drains battery faster and reduces the usable cleaning time per charge.
In robot vacuums and handheld models, the filter also determines how often the bin needs emptying and how much fine dust escapes during emptying. A filter that holds particles securely reduces secondary dust clouds and keeps the internal chamber cleaner. The design priority is therefore twofold: capture the fine fraction effectively, and keep airflow resistance low enough that the motor is not strained.
Celrith uses high-precision PTFE membrane, composite PP meltblown media or antimicrobial filter paper, depending on the model and performance target. These media are engineered to intercept PM2.5, micro-dust, dust mites, pollen and pet dander, preventing secondary pollution from the exhaust. The pore structure is designed for high porosity and low resistance, so the motor does not lose suction and overheating risk is reduced — which helps extend battery runtime.
The washable construction is central to the value. Instead of replacing the filter frequently, users can rinse and reuse it, maintaining performance across repeated cleaning cycles. For OEM customers, Celrith offers 100% structural and dimensional customisation: injection-moulded frames in cylindrical, flat or irregular shapes, with rubber sealing rings to ensure air-tightness. Whether you need a standard disc or a fit specific to your vacuum model, the filter can be built to your drawing or sample.

This filter is used by manufacturers and brands of handheld cordless vacuums, smart robot vacuums, mite removers, wet-dry cleaners and compact car vacuums. It suits product teams that need a reliable fine-dust barrier without sacrificing suction, and that want a washable solution to reduce end-user replacement frequency.
It is also a fit for aftermarket suppliers who need dimensional customisation across multiple vacuum models. Because the frame and sealing can be tailored, the same filter platform can serve several device families with different footprints, while maintaining air-tightness and low resistance.
Celrith products comply with REACH and RoHS environmental regulations, and compliance documents are available. The company holds ISO 9001, ISO 14001 and ISO 45001 certifications, and in 2024 obtained IATF 16949 automotive quality management system certification. These systems cover quality, environmental and occupational health and safety management across production.
Testing is carried out in a self-built laboratory accredited by CNAS (China National Accreditation Service for Conformity Assessment), which can issue reports on filtration efficiency, dust holding capacity and resistance. The 50,000 m² production base includes six cleanrooms totalling 20,000 m², supporting contamination-controlled manufacturing. With more than 20 years of filtration R&D and manufacturing experience, the company has developed over 1,000 filtration solutions and supplies customers in Europe, the US, Japan and Korea. Multiple automated production lines support monthly capacity in the millions of pieces, with IQC, IPQC and OQC controls in place. The company is located in Zhongshan, Guangdong, China.

It intercepts PM2.5, micro-dust, dust mites, pollen and pet dander from the vacuum's dust bin, preventing them from being exhausted back into the room. The media can be PTFE membrane, composite PP or antimicrobial filter paper, depending on the configuration.
The high-porosity, low-resistance design keeps airflow restriction low, so the motor does not lose suction and overheating risk is reduced. This helps maintain cleaning performance and can extend battery runtime compared with clogged or restrictive filters.
Yes. Celrith offers 100% structural and dimensional customisation, including frame shape (cylindrical, flat, irregular), size, filter media grade and rubber sealing rings for air-tightness. You can provide a drawing or sample for a fit-specific build.
The filter is washable and can be rinsed to maintain performance, reducing replacement frequency. Replacement intervals depend on use and dust load; we recommend monitoring airflow and washing when suction noticeably drops, then replacing if performance does not recover.
Share your device model, size or drawing, airflow or water flow, operating conditions and quantity. We will review and provide a quotation; samples can be arranged for evaluation, with details confirmed based on the specification.
