Best Kiesev in 2026

【INTRODUCTION】The filter membrane preservation box is specially designed for the sampling of atmospheric particulates and the separate storage of single filter membrane, so as to avoid the problems such as particulate loss on the filter membrane, deformation of the filter membrane and pollution of the sample caused by the way of storing the sampled filter membrane in aluminum foil paper bags, plastic bags, folding clips, etc.

【MATERIAL】The raw material of the filter membrane box is new polystyrene (inert material), which will not pollute the filter membrane with particles collected.

【PURPOSE】It is used for convenient storage, transportation and fixing of filter membrane.

20x20x1 replacement air filters for your furnace, air conditioner, heat pump, or HVAC system (actual size: 19.50" x 19.50" x 0.75")

MERV 13 synthetic media (comparable with MPR 1500 - 1900 & FPR 10) protects homes from bacteria and more by trapping 98% of airborne particles without impacting air flow

High-quality construction features an electrostatically charged, pleated design that captures more harmful particles and prolongs the products lifespan by 3 times that of fiberglass models

GRADE 1 : 15cm - Equivalent to Whatman qualitative grade 1, standard lab filter paper (150mm)

LAB FILTER - Routinely used in lab to determine fat content, extract solids and clarify liquids

CHEMISTRY CLASS - Filter paper can teach basic qualitative separations and paper chromatography
