Battpit Adjustable Replaceable Activated Activities Review

Package Contents and Mask Size: 1 washable mask with adjustable nose clip + 3 replaceable filters + 2 rotary breathing valves. One size fits most. Mask Dimension: 5.75 x 7.25 x 6.25 inches. Filter Dimension: 3.5 x 5.25 inches. Washable Mask and Washing Step: The premium nylon material is soft, breathable, low-weight, fast drying and washable. When washing the mask, please remove the filter and breathing valves first, then wash the mask gently in warm water and dry it in the air. Replaceable Filters and Replace Frequency: 4 layer non-woven material with activated carbon filter can block PM 2.5 particles and harmful chemicals. The life time of filters depends on the activities and environment when wearing. Normally we recommend the filter should be replaced in about 40 hours. And 20 - 30 hours in the heavy dust environment. Adjustable Velcro Strap and Elastic Earloop: The elastic earloop greatly reduces friction on ears, providing a more comfortable feeling, which can fix the mask on your ears. The Velcro strap on the back can be adjusted according to your head shape, and will not stick to your hair.
