VF3700 Wet Foam Filter 4 Pack Compatible with Ridgid Vacuums - Wet

In this review of the VF3700 wet foam filter 4 pack, the bottom line is clear: this set is for owners of 3-4.5 gal Ridgid wet/dry vacuums who need a simple, washable option for high volume liquid pickup. The reviewer found the filters snap on and off easily for quick cleaning and switching between filter types, and that a four-pack provides spare filters so routine changes every 5-6 months are painless. Overall this is a practical, value-oriented replacement for wet applications that emphasizes functionality over fancy features.

Key Features

• Wet foam design: Built for picking up high volume liquids with debris so the vacuum can handle wet messes without clogging the motor protection system.
• Snap-on cartridge: The VF3700 filter simply snaps on or off the shop vacuum for easy removal and quick cleaning between jobs.
• Four-pack convenience: Includes 4 replacement filters so you can rotate spares and replace every 5-6 months to maintain suction and cleaning performance.
• Washable and reusable: The replacement foam can be washed and reused, lowering ongoing costs compared with disposable-only options.
• Compatibility: Designed to fit a range of 3-4.5 gal Ridgid-style shop vacuums, making it a direct replacement for wet applications on those models.

Who It's For

This product is aimed at DIYers, workshops, and homeowners who own a 3-4.5 gal Ridgid wet/dry vacuum model and who regularly clean up liquid spills or wet debris. The four-pack suits users who prefer to have spare filters on hand so they can swap a soiled unit for a clean one without interrupting work.

It is less suitable for those who only run dry dust collection, users who require HEPA or fine particulate filtration, or owners of vacuums outside the listed 3-4.5 gal compatibility range who should verify fit before purchasing.
