Importantly Asked Questions
Customers from around the world have contributed to our FAQs. If you have any questions please get in touch HERE.
What size MetaMask should I order?
Use the Sizing Chart below to determine the correct size based on your weight or face size. In general, medium size typically fits women and large fit men.
How do I clean my Metamask?
Due to the nanotechnology filter embedded in the mask, it is best to ‘dip-wash’ with a drop of natural soap, teatree or eucalyptus oil, then patted dry and left in the sun and breeze. Do not machine wash or dry, as the nanofilter will capture dirt, impurities and minerals in the water and be less effective.
What is the life cycle of the mask?
Our ‘embedded filter’ Metamask is effective for up to 200 hours (appx 3 months) depending on air conditions. As the nanofilter becomes full of particulates, you will notice more resistance while breathing, which is an indication you need to replace the mask. Our new ‘Replaceable Filter Masks' are now available in our online store.
Can I change the filter of the Metamask?
We offer two variations of Metamasks – Embedded Filter which may be used for up to 200 hours (and cannot be replaced) and Replaceable Filter masks which can be replaced multiple times when filters require changing.
Is MetaMask suitable for people with sensitive skin?
MetaMasks are antibacterial & hypoallergenic, so can be safely used by anyone with pulmonary weakness such as asthma, bronchitis, allergies, and chemical sensitivity. MetaMask offers styles with organic cotton and bamboo with natural base plant dyes. The protective qualities of bamboo fiber are due to an antimicrobial bio-agent called 'bamboo kun' that occurs naturally in the fiber. Kun helps reduce bacteria that thrives on clothing and human skin, which in other masks can cause unpleasant odors over time.
How can I avoid the ear loops bending my ears forward?
Ear loops can be adjusted for a perfect fit by pulling the lower and upper straps through the latex rubber bead to seal the mask on your face and prevent air-leakage. Watch our instruction video HERE.
Is it normal to feel resistance when inhaling through a mask?
Metamasks are highly breathable while capturing most airborne pollutants, however as the nanofilter collects particles there may be some resistance to air-flow over time. If you find breathing through your mask difficult, try lightly hand-washing as described, drying in the sun and breeze, or replace your mask with a new one.
What makes MetaMask better than other masks?
MetaMask is the world's only air pollution facemask that combines natural, organic and sustainable textiles with an exclusive nanocococarbon matrix filter for maximum breathability and protection. Other masks are often poorly designed, uncomfortable, ineffective and ugly. Metamask filters capture 99.99% of toxic airborne pollution including dust, ash, smoke, exhaust, fumes, pollen, moulds, bacteria and pathogens. In addition Metamasks are extremely comfortable and highly fashionable for style-conscious citizens.
What is Nanofibre Technology?
Nanofibers are incredibly small fibres – one thousand times thinner than a human hair. Nanofibers form spiderweb-like structures which have an advantage over conventional or even natural fibres due to their incredibly large surface area and tiny pore size. This combination means maximum air flow and particle capture than other synthetic or natural filters, achieving greater efficiency down to PM0.3 microns. Metamask features a custom-engineered nanocococarbon fibre filter produced by Revolution Fibres in New Zealand.
Surgical masks are designed to protect the environment and others from the wearer, whereas an air pollution mask should protect the wearer from the environment. In general surgical masks offer very little if any protection. If you want maximum protection from air pollution, buy a Metamask.
Can I wear the mask with a beard?
Any facial hair can potentially cause air leakage, thus reducing the effectiveness of the mask. Metamask is the only mask on the market that features a stretchable chin-wrap to effectively seal the mask on your face, even with facial hair.
Why doesn’t Metamask use an exhale valve?
Metamasks, due to their superior and efficient nano filter technology have an outstanding breathability and therefore do not need exhale valve however, when practicing sport activities like running, a mask with an exhale valve might be better.
Are MetaMasks tested or certified by a recognised agency?
Metamask filters have been previously tested and certified by Nelson Labs, however our filters are going through some exciting evolution, so we generally pre-test at LANACO before testing at Nelson Labs in USA. LANACO is the leading filter-testing company in New Zealand.
