よくあるご質問

What type of material is polyurethane?

It is a soft elastic material widely used for things like cosmetics powder puffs.

Why did you decide to make your masks out of polyurethane?

The data shows that about 80% of people with allergies feel that masks are an ineffective countermeasure against pollen. Our efforts to develop a mask that could fit any shape of face without leaving gaps led us to settle on polyurethane as a material.

How effective is it at keeping out pollen?

It is capable of filtering out 99% of pollen.
However, no matter how high the degree of filter a product offers, if it doesn't fit you face pollen will get in through gaps between the mask and your face. Make sure to choose the right size when selecting a mask.

Doesn't such a tight seal make it hard to breathe?

The material has excellent air permeability, so doesn't interfere with breathing.* The porous filter technology employed by PITTA MASK delivers overwhelming air permeability unmatched by other polyurethane materials. * Feel may vary for individual users.

Doesn't it make your ears hurt?

Because it's made completely of polyurethane, the entire mask expands evenly so that your ears don't hurt*. Plus, the part that hooks over your ears has been made wider to keep ears from hurting. * Feel may vary for individual users.

Which way is up?

The pointed part shown in the illustration should be on top. See the back of the package for details. Please note that there may be a gap around the bridge of your nose if you wear the mask upside down. Any gaps around the face will allow pollen to get in. So please be careful to wear correctly.

I can't tell which is the outer surface and which is the inner surface.

The glued areas of the mask are on the outer surface. But the mask will function just as well if worn inside-out. Wear it whichever way you prefer.

How do you wash it? Won't it get stretched out?

Wash by hand, then dry away from direct sunlight. Can be washed and reused repeatedly, with filter performance unaffected, even after 3 washes (blocks 99%* of pollen).
Also, it will not get stretched out even when washed. Please wash daily after use.

Can I use detergent?

It's okay if you use a neutral detergent that is neither acidic nor alkaline. After washing, be sure to rinse thoroughly before you use it again.

The mask has an unusual odor.

You may notice the odor of the polyurethane material just after unsealing the package. Stop using immediately if the smell causes you to feel unwell.
If the odor bothers you, simply shake the mask lightly a few times after unsealing. Or, you can wash it by hand with your favorite detergent, etc. before use.

Why does the color change during use? Does color change indicate a change in effectiveness?

A yellowing of the surface does not mean the mask is dirty. This is a peculiar characteristic of polyurethane whose cause has not been determined. This yellowing does not affect product quality, so please continue to use as-is. If it bothers you, simply switch to a newer mask.

Does the mask block viruses or fine particulate matter (PM 2.5)?

We've developed the PITTA MASK2.5a for those who want protection from viruses or fine particulate matter (PM 2.5).

Where can I buy one?

You can find them at drug stores, convenience stores and variety shops in Japan, as well as from various online retailers. Just ask your favorite store if they have any in stock.
