Harvest Right Oil Filter Replacement Cartridges (3-Pack)

Fresh Cartridges to Keep Oil Filtering Effective, 3 Pack

A filter cartridge loads up with contaminants over time, and a spent cartridge can't clean pump oil properly. Fresh cartridges restore the filter system so it keeps separating water and debris from your vacuum pump oil. These Harvest Right cartridges are made for the Harvest Right oil filter.

The pack holds three cartridges, enough to keep spares on hand through many oil filtrations.

Frequently Asked Questions

When should I replace the cartridge?

Replace it when oil drains slowly through the filter or comes out still milky, cloudy or dirty. Frequent filtering wears cartridges out faster. Having spares means you never skip a filtration.

How do I install a new cartridge?

Remove the used cartridge from the filter's holder and press the new one firmly into place so it seals. Then filter oil as usual. Dispose of the used cartridge according to local rules for oily waste.

Do these fit other oil filters?

These cartridges are made for the Harvest Right oil filter system. Fit on other brands' filters isn't stated by Harvest Right. Use them with Harvest Right's filter for reliable results.

Why keep clean pump oil at all?

Water and debris in pump oil reduce how deep a vacuum the pump can pull, which slows freeze-drying cycles. Clean oil helps the pump run efficiently and last longer. Filtering with a fresh cartridge is the easiest way to keep it clean.
