The regular fits most adults. If you have a measuring tape handy, measure from the bridge of your nose where you would like the mask to sit, to under your chin.
Kids/Small: 13cm (Nose to Chin) x 22cm (Ear to Ear)
Small: 14cm (Nose to Chin) x 23 cm (Ear to Ear)
Regular: 15cm (Nose to Chin) x 25cm (Ear to Ear)
Large: 17cm (Nose to Chin) x 26cm (Ear to Ear)
Not every size comes in every colour.
Other than that, the four sizes are identical in terms of design, adjustable ear loops and pleats around the nose and chin.
Please note: Because of the stretch of the fabric, sizing can vary slightly.
Hand wash with warm water and hang to dry.
Please remove the filter when washing. Do not wash the filter.
The PM2.5 filters act as an additional barrier to protect against potential harmful airborne particles. Since the PM2.5 filters are not medical grade in that they cannot directly protect you against COVID, they really just act as an extra barrier.
With that being said, the PM2.5 filters need to be changed whenever they have become full of particulate matter 2.5 (PM2.5), which refers to tiny particles or droplets in the air that are two and one half microns or less in width (i.e. pollution).
When it becomes hard to breathe through the filter you should change them. This implies that it really depends how much you use the filter, how much moisture it picks up, and how much pollution is in the area you live.
