Review on 🔍 Polypropylene Disposable Face Mask Filter Insert (20 Pack) - 95% Efficient, 3 3/8" X 6" Size by Muleme Anderson

Ordered in July and received great 4" x 6" filters (they were actually a generous 4 3/8" x 6"). These filters were soft, flexible, ideal for homemade masks, and easily covered the nose and mouth area. Ordered again in August, although I did notice the sizes listed were smaller (3 3/8" x 6"). Some of the new filters are 1/4" smaller than advertised. Some of them are the advertised size. August filters are 1" shorter than July filters. They barely cover the nose and mouth area (depending on face size). If as your mask moves, the filter moves and tends to go down I was very happy with my first order but not with my second.
