In critical environments, the facemask is not “just PPE.” It is a contamination-control barrier intended to reduce droplet and particle shedding from the operator into sensitive zones. Mask performance depends on two factors: (1) a product that is engineered, processed, and supplied with the documentation your program expects, and (2) a gowning method that prevents the operator from contaminating the mask (and the clean area) during donning and use. Ansell BioClean™ MTA210-1 is positioned for that reality: sterile supply via gamma irradiation (SAL 10^-6), cleanroom-processed manufacturing, and a tie-on format that supports secure, repeatable fit when trained correctly.

• Sterile and aseptic environments where a sterile facemask is specified by SOP and gowning qualification.
• ISO Class 4 / Class 10 cleanrooms and critical work zones that limit operator droplet/particle contribution.
• EU GMP Annex 1 programs (sterile medicinal products) where gowning expectations include sterile facemask use in Grade A/B contexts.
• Laboratory and research controlled environments seeking standardized packaging and documented sterility.

• Sterile, documented supply: gamma irradiation with stated minimum dose (25 kGy) and SAL 10^-6, plus shelf life and storage guidance.
• Controlled processing: processed in a NEBB-certified ISO Class 4 cleanroom (manufacturer stated) to reduce contamination risk.
• Tie-on fit control: head ties support secure placement and can reduce ear/loop variability in some users.
• Cleanroom-compatible build: ultrasonically sealed edges and enclosed noseband are intended to support integrity and consistent fit.
• Program continuity: SOSCleanroom’s long-standing distributor relationship with Ansell supports stable supply. Our record includes multiple distribution awards, including 11 Texas Instruments Supplier Excellence Awards.

Manufacturer-stated material is polypropylene / polyethylene, with a layered construction: inner facing layer (non-woven PP/PE; hygroscopic), filtration layer (meltblown polyester), and outer layer (non-woven spunbonded polyester; hydrophobic). The noseband is plastic coated steel and is described as fully enclosed and malleable for fit control.

The edges are ultrasonically sealed and the fastening system uses non-woven polypropylene ties, supporting a tie-on gowning approach. Packaging is 1 mask per sealed inner PE bag, supporting controlled dispensing and reduced handling exposure during entry.

For facemasks in cleanrooms, “performance” is not only filtration values. It also includes: packaging discipline, sterilization documentation, fit repeatability, and operator technique. A highly specified mask can still fail contamination control if users touch the mask body while donning, wear it under the nose, or repeatedly adjust it mid-task.

The manufacturer lists filtration performance values (PFE/BFE/VFE) and differential pressure as a breathability indicator. Treat these values as product-specific test outcomes under the stated test basis; your facility SOP and risk assessment determine suitability for your exact process.

• Sterility basis: gamma irradiation; SAL 10^-6; minimum dose 25 kGy (manufacturer stated).
• Packaging discipline: 1 mask per sealed inner PE bag supports controlled dispensing; verify inner/outer packaging integrity at receiving and at point-of-use.
• Storage alignment: maintain dry/cool storage (<40°C) away from sunlight and fluorescent light as stated.
• Shelf-life control: confirm expiry/lot controls using your internal receiving procedure and documentation requirements.

This mask supports contamination control only when the entire gowning system is controlled: correct change-room sequencing, validated garments, qualified operators, and disciplined movement. Treat the mask as a critical component of your personnel contamination barrier.

• Touching the mask body during donning: handle by ties only.
• Wearing below the nose / incomplete chin coverage: defeats droplet containment intent.
• Loose ties or poor nose fit: increases leakage and prompts repeated adjustments.
• Reusing single-use masks: increases contamination risk and breaks documentation discipline.
• Ignoring “wet mask” replacement: moisture changes barrier behavior and promotes handling.

Closest alternatives are typically other sterile cleanroom mask formats that match your gowning method (ties vs loops) and documentation needs. Compare packaging discipline, sterility method/SAL basis, and operational fit (fogging, comfort, adjustment frequency).

• Ansell MEA210-1 (looped): same general program with ear-loop format for faster donning in some workflows.
• Ansell BDBS (DB pouch-style): alternate sterile mask format used in Class 10 / ISO 4 programs.
• Ansell BDBS-G (neck guard): adds neck coverage in applications that require broader facial/neck barrier control.

MTA210-1 is best suited for controlled environments where sterile mask supply and documented processing are part of the contamination control strategy. It is commonly selected when the operation wants repeatable packaging, defined storage/shelf-life controls, and a tie-on fit method aligned to gowning qualification.
