Problems with disposable masks

• The sealing is not tight. Even if the sealing seems to be OK, it is not reliable enough in actual application.

• Disposable N95 masks are limited by the actual flow area of the face, and the filter material filtration grade cannot be too high; otherwise it will increase breathing resistance and affect normal use.
• Moisture in exhaled breath reduces filtration efficiency and increases respiratory resistance.

How does AYO HC achieve a superior sealing fit?

• The mask is made of soft silicone material and is specially designed for 3 head sizes in 3 mask sizes: large, medium and small, which can fit 99.7% of human face contours. This greatly improves the sealing and tightness compared to disposable masks.
• The design of the mask cushion is also unique, with a sufficient elastic range, and is made very thin, which further enhances the sealing fit between the mask and the face.
• The overall fit factor exceeds 2000, which is 20 times higher than the N95 level.

Designed for three head sizes, suitable for 99.97% of human face contours

How does AYO HC achieve higher filtration efficiency?

• Using a higher level of filter material than N95 as the main filter element, the filtration efficiency for particles 0.3um and above is >99.9%, compared to the N95 standard of 94%, achieving a protective effect 50 times higher than the N95 level.
• At the same time, the filter element adopts pleated filter material, which greatly increases the actual effective flow area. Although the filter material level is improved, the airflow resistance can still be controlled within an acceptable range, and the peripheral size of the filter element can still be kept small.

How does AYO HC prevent moisture from reducing filtration efficiency?

The built-in air inlet valve of the silicone mask prevents moisture in each exhalation from entering the main filter element, thereby preventing the reduction of filtration efficiency and increasing in breathing resistance caused by moisture, thus extending the life of the filter.

Best-in-class battery life with battery replaceable

• High battery capacity
• Extendable service life with a user-replaceable battery

Up to 16 hours of battery run time

Best-In-Class wearability for doing tough jobs

• Novel and State-of-the-art blower design – Deliver powerful flow with streamlined sizes

A sophisticated computational fluid dynamics design tool in conjunction with a novel motor design brings about a patented streamlined blower with powerful flow generation.

• Intelligent Breath-responsive Flow Control – Comfortable and Natural to breathe while ensuring positive pressure protection.

• Innovative respirator structure – Comfortable to wear doing tough jobs.
• Low profile and lightweight – great field of view and hassle-free in operation.

The patented structure spreads the main unit around the head, with the blower fitted inside a flexible pipe loaded at the back of the neck, ensuring easy head movement while doing physically demanding jobs.

• Patented Push-fit & Twist-release connection – Very easy and reliable to operate.

Best-In-Class Protection and Lowest In-class Costs

• Fool-proof Protection – elimination of any misuse due to a user forgetting to fit a filter before use.

The filter element must connect to the Power Unit inlet in order to work, thus it is not possible to have the system connected without the filter element properly fitted – A fool-proof and intrinsically safe design.

• Innovative Sealed Airpath – Dust-tight and reliable protection by design

• Superb silicone mask cushion and seal – Best-In-Class protection and comfort.

The silicone masks come in 3 sizes and are specially designed for 3 representative human head models, achieving an adaptive soft cushion that closely matches the facial profile of up to 99.7% of human demographics, resulting in a superb fit to cover most human faces, thus providing more reliable protection and comfort.

• Advanced manufacturing techniques – Lowest in-class ownership and running costs.
