Hexa Frequently asked Questions

Yes, HEXA's 4-level fan speed will circulate air into the mask and keep your breathing easy and cool inside the mask.

Hexa uses fans to draw in air through the filter and circulate within the mask, saving you the effort of doing it yourself. This allows you to breathe easily and comfortably while simultaneously keeping you cool inside the mask.

Our filter can help protect against particles with a median mass aerodynamic diameter (MMAD) of 0.3 micrometers; in this respect our filter is the equivalent to other 95-level rated filters (in fact our filter also filters oil based particles too).

Hexa uses a proprietary 5-layer composite filter which includes a traditional melt blown static charge filter and a high tech nano membrane. The filter can capture both oil based and non-oil based airborne particles with >95% efficiency. Technical terms for our filter materials include: ethylene vinyl acetate (EVA), polypropylene (PP), polytetrafluoroethylene (PTFE).

The fans produces a noise in the range of 50 to 65 dBA. That range is based on clean air flow from 50 liter per minute to 150 liter per minute. So the decibel level varies based on how fast the fans are running, but no higher than 65 dBA at the highest setting. By comparison,  a normal conversation is 60 dBA. 

If the vertical distance between the middle of the eyes and the bottom of the chin exceeds 9.5 cm (> 9.5cm), then Hexa should fit, however there may be exceptions and we cannot guarantee this fitting guideline will apply to you.

Please note that an air purifier mask product is considered a 'personal' item and for hygiene reasons Koolmask is unable to exchange any air purifier mask that has been removed from its packaging and fit attempted.

A mobile power bank is not included in your package and is not sold on our site. 

We recommend a mobile power bank with a USB type A output of 5V/2.4A and a capacity equal or greater than 5,000 mAh.  You may use a power bank that is 2.4A or higher of charging speed. 1.0 is the slowest charging speed and should be avoided when charging Hexa to avoid slow charging time.

Hexa’s air filter should be worn for a maximum of 40 hours and should generally be replaced regularly.

We recommend disposing of the filter if it becomes damaged, soiled (noticeably discoloured), or breathing becomes difficult. Even if none of these things happen, it's recommended to dispose of filters after 40 hours of use or 7 days after removing the filter from its original packaging, whichever comes first.

HEXA'S fit factor is 200, which means leakage is less than 0.5%. By comparison HEXA has a higher / better fit factor rating than most other masks. that require a fit factor of 100, which means the air leakage is less than 1%.

The outer layer of our filter is waterproof, however beyond that Hexa is not waterproof and water could enter inside the mask.  If water, sweat or liquid were to enter the mask around the area of the fans, short circuit protection inside the mask will cause the fans to stop and reset once the fans are dry.

When Hexa is dirty, you can clean it by soaking a soft cloth in a diluted solution of neutral detergent, and wring it well before gently wiping the air purifier mask. Do not use solvents such as thinners, benzene, or alcohol, as they may damage the product.

Red, black, white, pink and green are available for your filter cover. Our Air Purifier mask is modular and the filter cover can be easily swapped out for a new exciting colour. You have the option of adding more than one filter cover colour to your shipping cart.
