FAQ

How long can I use your masks and filters for?

Generally speaking, for covid, our masks and filters are designed to be one-off use, and how often it is changed depends on the conditions of use and duration of use.

For a high-risk environment we recommend changing it after a single use (e.g. in crowded places) but if it is for a lower-risk environment (e.g. walking outdoors where you may or may not walk past others) you may decide to change it less frequently.

If not mishandled, our masks and filters can last one full day’s use easily.

Are your masks and filters washable?

Our masks and filters are not designed to be washed. Washing compromises the filtration performance of the filter so it is not recommended for covid applications.

Do I need to purchase HELIX.iso filters for your mask range?

No, our Brezy Masks, AirCare Masks and Waire P2 Respirators all have filters built-in. The HELIX.iso drop-in filters are designed for sewn cloth masks that have pockets to hold a replaceable filter.

If you would like to buy a cloth mask that accommodates HELIX.iso filters, see the list of our sewing partners we have worked with: https://lanaco.co.nz/filters/

Which way do I insert the HELIX.iso filter into my cloth mask?

We recommend inserting the HELIX.iso filter into the pocket of your cloth mask so the printed side of the filter is facing the wearer.

Do you offer different mask sizes?

Our Brezy and Waire P2 mask sizes are generally a M/L size, but can fit a wide range of face sizes since the head straps hold the mask snugly in place.

What do you recommend for international air travel?

We recommend a combination of our Brezy Mask and Waire P2 Respirator.

Both of these use head straps so holds the mask snugly against the face, giving the best possible level of protection for you.
The Brezy is more breathable so we recommend using them for lower-risk areas (e.g. mixed indoor/outdoors, fewer people, inside the plane cabin).
The Waire P2 offers higher protection so we recommend using them for higher risk-areas (e.g. amongst crowds, tight indoor spaces with little ventilation).

This is the same advice and product combination that we supplied to the NZ Olympic Team when they went over to Japan for Tokyo 2020.

Are your masks and filters biodegradable/compostable?

While all of our products use wool fibre, they are not fully biodegradable or compostable. However, this is something we are working on as a research goal in the near future!

Will the wool cause allergic reactions?

So far we have not received any complaints about allergies. Most wool “allergies” are actually sensitivities with the skin, which only (sometimes) happen when there is direct contact between the ends of the wool fibres with the pores on the skin, causing slight irritation. As there is no next-to-skin contact on any of our products, this should not be a problem.

It is difficult to bring the lower strap over my head. How do I put the mask on?

If you find there is too much strain on the elastic when putting on our masks, try using this alternative fitting instruction. Watch the video below.
