Oltaven dust collection bags with plastic cover plates are finished filters designed for robot vacuum auto-empty docks, handheld vacuums, and commercial vacuum bins. They capture fine dust, PM2.5, dust mites, pollen, and hair, preventing secondary pollution from exhaust air. This product is for appliance brands, OEM/ODM buyers, and distributors who need reliable dust bags with custom plastic cover plates and sealing options.
A dust bag is more than a piece of fabric. The finished filter is the result of combining selected media with forming processes: pleating or layering, framing, and sealing. Oltaven uses multi-layer composite PP meltblown media, which provides high particle capture while maintaining low airflow resistance. The plastic cover plate is injection-molded to fit the specific docking station, and the sealing method—such as a sliding handle for automatic closure—determines how cleanly the bag can be replaced. The way these elements are assembled directly affects the bag's efficiency, resistance, and dust-holding capacity.
We sell finished filters, not just media. That means we control the entire process: from choosing the right PP nonwoven and meltblown layers to designing the plastic cover plate and integrating the sealing mechanism. This approach ensures that the final product meets the performance requirements of your vacuum model.
Three key factors determine how a dust bag performs in real use: media choice, forming, and sealing. First, the media: multi-layer composite PP meltblown creates a dense network that traps fine particles, including PM2.5 and allergens, while its high porosity allows air to pass through with low resistance. This low resistance helps maintain strong suction power and motor efficiency. Second, the forming: pleating or layering increases the surface area for dust holding, so the bag can store more dust before needing replacement. Third, the sealing: a well-designed cover plate and closure mechanism prevent dust from escaping during removal, avoiding secondary contamination.
In addition, the plastic cover plate must match the docking station precisely. Oltaven offers both hard cardboard and eco-friendly plastic injection-molded cover plates, with options for sliding automatic sealing and activated carbon composite for odor control. These choices affect fit, ease of use, and overall filtration reliability.
Because we produce the finished filter, we can adjust each of these variables to meet your specific requirements for efficiency, resistance, and capacity.
Oltaven dust bags are used in smart robot vacuum auto-empty docks, handheld wireless vacuums, and commercial vacuum bins. They are suitable for households with pets, allergy sufferers, and anyone who wants to reduce dust exposure during emptying. The bags are also used in commercial settings where frequent cleaning is required.
Our custom plastic cover plates are designed to fit major robot vacuum brands, and we can develop new models based on your samples. The bags are compatible with various docking stations and can be customized for specific vacuum models.

Oltaven specializes in OEM/ODM manufacturing of filtration products and has developed more than 1,000 filtration solutions for customers worldwide. Our 50,000 m² production base includes six cleanrooms totaling 20,000 m², where dust bags are produced under controlled conditions to prevent contamination. We operate a CNAS-accredited laboratory that can test filtration efficiency, dust-holding capacity, and airflow resistance. Our quality management systems are certified to ISO 9001, ISO 14001, and ISO 45001, and we added IATF 16949 certification in 2024. All materials comply with REACH and RoHS regulations, and we can provide compliance documentation for your market.
To begin your custom dust bag project, please provide the following details: your device or vehicle model, the required size or a drawing, the airflow or water flow specifications, the operating conditions (such as temperature and humidity), and your estimated quantity. Our team will respond promptly with a tailored solution. Contact us to discuss your requirements and receive a quote.
Resistance depends on the media's pore structure and the way the filter is formed. Multi-layer PP meltblown media with high porosity allows air to pass easily, while pleating or layering increases surface area without blocking airflow. The plastic cover plate and sealing method also affect how smoothly air moves through the bag. Oltaven optimizes these factors to achieve low resistance and maintain strong suction.
An OEM project starts with your inquiry, where you provide the device model, required dimensions or drawing, airflow specifications, operating conditions, and estimated quantity. Our engineering team then proposes a design and provides a quotation. After you approve the proposal, we produce samples for testing, typically within 2–3 weeks. Once samples are approved, we proceed to mass production.
Our dust bags use multi-layer composite PP meltblown media that captures fine dust, PM2.5, dust mites, pollen, and hair. The exact efficiency depends on the media grade and application, but our design targets high particle capture while maintaining low airflow resistance. All products are tested in our CNAS-accredited laboratory for filtration efficiency and dust-holding capacity.
Yes, we offer full customization of the plastic cover plate, including dimensions, clip structure, and opening position, based on your device model. We also provide options for sliding automatic sealing to prevent dust spillage, and activated carbon composite for odor control. Cover plates can be made from hard cardboard or eco-friendly plastic injection molding.
For standard specifications, the MOQ is typically 5,000–10,000 pieces. Custom products have MOQs that depend on the complexity of the specification. Lead time for standard stock items is about 7–15 days, while custom orders (including mold development) usually take 30–45 days, subject to order confirmation.
Yes, we provide samples for evaluation. For new developments, our engineering team can produce samples within 2–3 weeks after receiving your sample or detailed specifications. Sample fees and shipping costs are typically borne by the customer, but we can discuss this based on the project.
Replacement frequency depends on usage and dust volume. As a general guide, replace the bag when it is about two-thirds full or when suction power noticeably decreases. Our bags feature a sliding automatic sealing design for clean disposal without touching the dust.
Our dust bags are manufactured under ISO 9001, ISO 14001, and IATF 16949 quality management systems. Materials comply with REACH and RoHS regulations. We can provide compliance documentation for your target market. Our CNAS-accredited laboratory ensures each batch meets performance specifications.
