Mask Filter Insert Refill Pack

$6.25

What are your mask filters made of?

The mask filters are made from non woven fabrics comparable to the ones used for surgical masks.

According to tests from the Singapore A*star lab, our mask filters have 95.5% - 99.8% BFE reading after 15 washes, which means they retain their efficacy fairly well even after repeated washes.

We recommend that you change the filter after 10 washes.

Mask Filter Insert

I am satisfy with the item I have purchased.

Mask Insert

The quality is good. The rectangle shape makes it a difficult to insert the filter. I think it would be better if the filter was shaped to the shape of the mask, slightly bent inwards on the outer edges.

Useful and great service!

Would be great if there's detailed instructions on how to insert it properly, but otherwise, great and affordable product and impeccable service!

Like the size

Fit the mask well. Will order more.

Mask filter insert refill

I prefer the square piece to this rectangular one as it's difficult to tuck it in. With the square piece folding a side triangle is even , not for the rectangular. Could it be the user doesn't know the correct way to insert it
