LIFETIME:

Breakthrough time of a filter is tested according to EN 14387+A1 at humidity 70% and flow rate 30 l/min, which is equivalent to the volume of air per minute used by an average person carrying out medium heavy work. The approximate lifetime (usage time) of a filter may, under normal conditions, calculated by comparing the concentration at the workplace and the minimum Dynamic Adsorption Capacity (DAC) for the filter.


STORAGE AND MAINTENANCE:

The filters are sealed in plastic bags by the manufacturer. Store the filters unopened in a clean place at even temperature, most appropriate at -5 to +30°C and relative humidity below 80%. Sealed filters tolerate also conditions of -30 to +50°C and RH below 95%. The storage period (month and year) for filters is marked on the filter label. Do not try to regenerate the filters. Never clean the filters with compressed air or compressed water.


DISPOSAL:

After use, the filters are special refuse. Make sure that they are disposed of according to the filtered substance (gases or particles) in accordance with current waste treatment regulations. If the product is to be disposed of, it should be dismantled from the respirator and disposed of as solid waste. Please see local authority regulations for disposal advice and locations.

Nice leggings......but
Special Size: 19" Capri without Pockets, Size: Small, Color: Taupe
So, I bought two pairs on sale....one in navy and the other in taupe. Both pairs have a streak mark on the same side, same exact area. I'm on the fence about returning them but I did get them on sale and if the mark doesn't come out in the wash, I can't really wear the in public unless I wear something long to cover the upper thigh area. They fit great and are very comfortable but then there is that unsightly mark. For reference, I am just under 5'0, 105 lbs and bought size small. I will have a think about it the next few days about returning them...or not.

Honest Review- Recommend
Color: Black, Size: 4-5T
Material is of good quality, it is flowy enough that she doesn’t sweat or get too hot. The length is a tad longer which I don’t mind for my 4 yr old of average height. She thinks it is comfy and loves wearing it to the golf course to match mom or to the park or pickleball courts. No built in shorts on this dress, which is okay considering how often we use the restroom.
