Ecnaka 3 Pack 90585 Foam Sleeve Filter and 3 Pack 90107/90137 Wet Dry Vac Filter for Most Shop Vac 5 Gallon and Above Vacuum Cleaner,Vf2002 Dry Discs Filters with 3 Retaining Bands,Replace# 9058500, 9010700

Why I swapped in this replacement filter kit

My shop vac does a little bit of everything—chasing drywall dust on remodel days, collecting planer shavings in the shop, and slurping up the occasional spill. That mix means filters matter. I wanted a set I could rotate, wash, and keep on hand without paying OEM prices. After several weeks of use, the Ecnaka filter kit has settled in as my go-to consumable set for 5-gallon-and-up Shop-Vac style units.

This kit includes three foam sleeves for wet pickup (90585), three dry filter discs (90107/90137), three retaining bands, and a small cleaning brush. I ran it on a 5-gallon Shop-Vac and a larger 12-gallon unit, moving between fine dust, general debris, and wet cleanup to see how it held up.

Compatibility and what’s in the box

The basics are covered well. The foam sleeves slide onto the cage for wet pickup, and the non‑woven fabric discs are intended for dry pickup (they go over the foam and are held in place with a band or retainer ring). If your vac originally used a retainer ring, you can still use it; the included rubber bands do the same job but aren’t quite as rigid. The brush is a nice touch for dry knock-off.

An important note on fit: this kit is designed for most 5-gallon and larger Shop-Vac style machines, but it does not fit certain portable, wall-mount, or long-life models. If you have a 5-gallon portable H87S, a 5-gallon HangUp or wall-mount, or a 6-gallon long-life P12S, you’ll need a different setup. For everything else in that common “5 gallons and up with a foam sleeve/dry disc system,” the fit has been spot on.

Installation and fit

Out of the bag, the foam sleeves look a touch undersized. Once you start them over the cage and “walk” them down evenly, they stretch into a snug, uniform fit. I actually prefer this tighter feel—no slack, no sag, and better contact around the base.

The dry discs are slightly generous in diameter compared to some OEM pieces I’ve used. That’s not an issue; it just means you need to take an extra second to smooth the pleats around the circumference so the retaining band (or ring) sits flat. With the band in place, the disc doesn’t budge. I tested both the included bands and my original ring; the ring is quicker to use and more durable, but the bands work fine and seal well if you seat them evenly.

A quick tip for fast, clean installs:
- Seat the foam sleeve first and check the float moves freely.
- Drape the dry disc evenly over the foam, keeping the fabric centered.
- Install the band or ring in one pass, then run a finger under the band to pull any trapped fabric into place so the entire edge is captured.

Performance on dry debris

I started with shop dust—table saw fines, planer shavings, and general grit from the floor. Suction felt unchanged from my baseline, and the disc filter caught fines without visible plume at the exhaust. The non‑woven fabric is a good balance of breathability and capture: airflow stays strong, but the motor cage and foam underneath remained clean after extended use.

I pushed into finer material next: drywall dust from a sanding session. With the foam sleeve plus disc in place (as intended for dry pickup), the vac kept its punch, and there wasn’t a telltale haze in the air or a gray film on the tank lip. Afterward, I tapped the disc out and saw even loading—no thin spots or torn seams. If you frequently deal with ultra-fine dust (plaster, cement, or ash), I’d still pair this setup with a collection bag or a HEPA cartridge when the job requires it. But for typical renovation dust and shop fines, the capture is exactly where it needs to be.

Performance on wet pickup

For wet tasks, I ran only the foam sleeve, as you should. It handled standing water and a muddy slurry without collapsing or shedding. The foam here is slightly less dense than some OEM sleeves I’ve used, which makes it quicker to rinse and dry. Motor protection was solid: no splash-through, and the float shutoff behaved normally. If you’re regularly vacuuming very fine silt in water, expect to spend a bit more time rinsing the pores clear, just as you would with any foam sleeve.

Washability and maintenance

Both the foam and the fabric discs are washable and reusable. I rinse the foam under warm water, squeeze (don’t wring) from top to bottom, and let it air dry completely before reinstalling. The dry discs tap clean easily; for deeper cleanings, I rinse from the clean side out to avoid driving fines deeper into the fabric. Air-dry thoroughly—overnight is safest.

After several wash/dry cycles:
- The foam retained shape and elasticity, with only minor surface pilling.
- The disc filters didn’t fray or split at the seams.
- The rubber bands stretched slightly but remained snug; if you have an OEM retainer ring, it’s worth using for longevity and speed.

The included brush is handy for quick knock-offs between full cleanings.

Airflow and motor protection

Filters only help if they don’t choke your vac. With this kit, airflow remained strong across all tests. The non‑woven discs are breathable enough that I didn’t notice a meaningful dip in suction, even as the disc started to load. Just as important, the foam sleeve and disc together keep debris off the motor cage, which protects the motor and helps maintain consistent performance over time.

Durability

Nothing here feels disposable in a single-use sense. The materials aren’t brittle, seams are clean, and the foam rebounds after compression. The rubber bands are the one component that feel consumable; they’ll do the job, but over many cycles they’ll show more wear than the filters themselves. That’s typical for band-style retainers. If your vac shipped with a rigid ring, hang on to it.

Value

The value proposition is the main attraction: three foam sleeves and three discs means I can run one set, wash a second, and keep a third ready to go. For busy shops, that rotation matters, especially when foam needs a full air-dry. Compared to buying single OEM pieces, this kit keeps costs down without forcing performance compromises for everyday use.

What could be better

• The retaining bands work but aren’t as durable or convenient as a rigid ring. If you have the ring, use it.
• The foam’s slightly looser feel makes it faster to rinse but may allow a bit more micro-fines through if used alone for unusual dry tasks. Use the disc for dry pickup and you’re fine.
• As with any non-HEPA setup, ultra-fine dust jobs are best paired with a collection bag or cartridge filter when the work demands it.

Practical tips

• Always dry the foam completely before reinstalling to avoid mildew and to preserve airflow.
• For dry pickup, run the disc over the foam; for wet pickup, remove the disc and use foam only.
• Keep a rotation: one set in use, one drying, one staged. You’ll never be tempted to reinstall a damp filter.
• Check the float in the vac’s lid after installing the foam to ensure it moves freely.

Recommendation

I recommend this Ecnaka filter kit for anyone running a 5-gallon or larger Shop-Vac style vacuum who wants reliable, washable filters at a sensible price. The fit is snug, the filtration is solid for general shop and renovation tasks, and the 3-pack rotation makes maintenance easy. While the included bands aren’t as robust as an OEM retainer ring and the foam skews slightly toward easy-rinse rather than ultra-dense, those are minor trade-offs given the overall performance and value. If you regularly tackle ultra-fine particulate and need HEPA-level control, keep a cartridge or bag in your arsenal. For everyday wet and dry work, this kit is a dependable, economical choice.
