9 Pack VF3501 Shop Vac Bags for Ridgid 3, 4, 4.5 Gallon Wet/Dry Vacuums Fit RIDGID Vacs Models# WD4070 WD4080 WD4550, High Performance Dust Filter Bags made of NEW PET Material, Tear Resistant

**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 pollution. It also lasts longer, so frequent replacement is unnecessary.
**2-Ply Filtration: ** PET bags are built with two layers of filtrationa meltblown nonwoven inner layer and a finer filtration outer layerwhich can efficiently capture smaller particles than ordinary paper materials on the market.
**Moisture Resistance: ** PET material offers moisture resistance. It won't become soft or dissolve like paper bags when stored in a humid environment, nor will it get moldy easily like standard non-woven fabric bags.
**Electrostatic Adsorption: ** Static electricity is generated inside the PET bag while the vac is operating. Instead of increasing thickness and density 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. Simply remove the existing bag, place the new one in the vacuum, and you're ready to go.
