This dust bag is a multi-layer composite PP meltblown filter bag with a reversible paper cap, designed for automatic dust collection bases of robot vacuums and handheld vacuums. It captures fine dust (PM2.5), dust mites, pollen and hair, and its high-porosity structure keeps airflow resistance low so suction stays strong. Ranveth manufactures it with flexible sizing and cap options for OEM projects. It suits appliance brands and vacuum OEMs that need consistent filtration and a clean bag-change experience.
The core of this bag is a multi-layer composite of high-precision PP (polypropylene nonwoven plus meltblown) and antibacterial filter cotton. Each layer has a job: the outer nonwoven carries the dust load and protects the meltblown layer, while the meltblown layer does the fine particle capture. The antibacterial filter cotton adds protection against microbial growth inside the bag. This pairing is what sets efficiency, airflow resistance and service life: a high-porosity breathable design keeps resistance low, and the high dust-holding capacity means the bag fills without choking the motor. The reversible paper cap is part of the structure, not an add-on: it lets the bag be inserted and removed cleanly, and it can be combined with a sliding handle for automatic sealing. For odour control, an activated carbon composite version is available. The result is a bag that filters to a high standard while preserving the suction the appliance was designed to deliver.

This bag is used in automatic dust collection bases (docks) of smart robot vacuums, in handheld wireless vacuums, and in commercial vacuum bins. In robot vacuum docks, the bag receives dust emptied from the robot's bin, so it must handle a mix of fine dust, hair and debris without losing airflow. In handheld vacuums, the bag captures what the cyclonic or bagless system passes on, protecting the motor and keeping exhaust clean. Commercial vacuum bins benefit from the high dust-holding capacity and the reversible cap that makes emptying cleaner. Because the bag is customised to the device, it fits the dock or bin interface precisely, whether the cap is paperboard or injection-moulded plastic. The activated carbon version is available where odour from the collected dust is a concern. Ranveth supplies these bags to appliance brands and vacuum OEMs that need a reliable consumable matched to their equipment.

Ranveth's approach to dust bags is grounded in test-backed media choices. Our in-house laboratory is CNAS-accredited (China National Accreditation Service for Conformity Assessment) and can issue test reports on filtration efficiency, dust-holding capacity and resistance, so the media pairing we recommend is supported by data. We manufacture in a 50,000 m² plant, which includes six cleanrooms totalling 20,000 m², to control contamination during production. Our quality management system is certified to IATF 16949 (achieved in 2024), ISO 9001, ISO 14001 and ISO 45001. Products comply with REACH and RoHS environmental regulations, and we can provide compliance documents. With more than 20 years of filtration product development and manufacturing experience, we have supplied customers in Europe, the United States, Japan and South Korea for over two decades. We support OEM/ODM projects with customisation of size, structure, filter grade, frame material, logo and packaging, and have developed more than 1,000 filtration solutions. Multiple automated production lines give a monthly capacity of millions of pieces. Quality control follows IQC, IPQC and OQC processes. Our address is Zhongshan, Guangdong, China.

It uses a multi-layer composite of high-precision PP (polypropylene nonwoven plus meltblown) and antibacterial filter cotton. The nonwoven protects the meltblown layer, which captures fine particles, and the antibacterial cotton adds protection against microbial growth. An activated carbon composite version is available for odour control.
The high-porosity breathable design keeps operating airflow resistance very low, so the vacuum motor does not have to work harder as the bag fills. Combined with high dust-holding capacity, the bag maintains strong suction throughout its service life. This pairing is central to how Ranveth specifies the media.
Yes. We customise 100% to device dimensions and offer hard paperboard caps, eco-friendly plastic injection-moulded caps, and sliding automatic sealing. Send us a sample or 3D drawing of your dock interface and we will develop a matching bag.
Standard specifications typically have an MOQ of 5,000–10,000 pieces, while customised products are quoted based on complexity. Standard stock orders ship in about 7–15 days; customised orders including tooling usually take 30–45 days. Lead time is confirmed at order confirmation.
We welcome sample requests. Standard samples usually ship within 3–5 working days; customised samples typically take 7–15 working days depending on structure complexity. Small sample quantities can be provided free of charge (freight collect), and sample fees for larger or tooling samples can be deducted from the order payment.
Replacement interval depends on dust load and appliance usage. Because the bag has high dust-holding capacity, it typically lasts until it approaches full, and the reversible cap allows clean removal. We recommend changing it when suction noticeably drops or when the appliance indicates the bag is full.
Our in-house laboratory is CNAS-accredited and can issue test reports on filtration efficiency, dust-holding capacity and resistance. The company is certified to ISO 9001, ISO 14001 and IATF 16949 (achieved in 2024), and products comply with REACH and RoHS. We can provide compliance documents on request.
