Replacement Filter Paper Filter Sheets Insert 5 Layers Filter Cloth Replaceable Filters-100pcs

Great price.

I have two masks that require me to slot a filter into and they fit perfectly.The only thing I don't know is, how many times can I use the filter? I wash my mask every time I come back, but I don't throw the filter away each time.

Very, VERY reasonably priced but the pleasure taken out of it by the incredibly long delivery time. Before ordering , make sure, a) you're not in a hurry and b) the size - PM 2.5 will fit your mask.

they look as though they do the job... you cant see through them. I did have a couple of others with a different makers mask and they were dreadfull !

I bought these filters because they fit the mask that I bought. Filters are very thick witch give me confidence when I were them. Recommend

These appear to be thinner than the standard although they state they are 5 layers. They are cheaper than others which could mean they are not as good.

I will get them again there great

Tried this product and found it very difficult to bresth through.

Vet inte riktigt om dom här.

Todo perfecto, y antes de lo previsto, buen vendedor

Halten was sie versprechen.

Presi per un'eventuale seconda ondata covid, ma spero di non doverli usare!!!Il prodotto sembra fatto bene, la misura è adatta per le mascherine non chirurgiche, con tasca per filtro. È arrivato con un mese di anticipo.

Fit great into the face masks. Excellent price, will be buying more in the future. Thank you
