15 Pack VF3501 High Performance Dust Filter Bags made of NEW PET Material Fit Rigid 3, 4, 4.5 Gallon Wet/Dry Vacuums Models# WD4070 WD4080 WD4550, Tear Resistant, Part # 23738 WS32045F

**Durability: ** PET (polyester fiber) is considerably stronger than paper or non-woven fabric. It resists tearing from stretching or light impacts even when full of dustpreventing leaks and secondary contamination. It also lasts longer, so you won't need to replace it as often.
**2-Ply Filtration: ** PET bags are built with two layers of filtrationa meltblown nonwoven inner layer and a finer outer filtration layerwhich can effectively capture smaller particles than standard paper materials on the market.
**Moisture Resistance: ** PET material offers moisture resistance. It won't become soft or dissolve like paper bags when kept in a humid environment, nor will it easily develop mold like ordinary non-woven fabric bags.
**Electrostatic Adsorption: ** Static electricity is generated inside the PET bag while the vacuum is operating. Rather than increasing the thickness and density of the bag to block dust, good filtration efficiency is achieved by attracting dust through static electricity. This ensures effective filtration while minimizing the loss of suction power.
**Tool-Free Installation: ** These bags are designed for simple installation. The rubber seal and cardboard frame ensure a secure fit. Just remove the existing bag, insert the new one into the vacuum, and you're all set.
