Can you replace one bubble bag without buying another complete set? Yes, when the replacement matches the required filtration specification and fits the container and remaining bags. A matching gallon label or bag color alone is not enough to establish compatibility.
This guide is for buyers replenishing individual bags, distributors building replacement stock and purchasing teams comparing a new supplier with an existing set. It focuses on fit and reorder control, rather than choosing a filtration sequence.
Start with the bag you need to replace
Record the existing bag’s supplier reference, nominal capacity, marked micron rating and construction. Photograph the complete bag, opening, base, label and seam arrangement. If the label is missing, ask the original supplier for the specification; appearance does not establish the aperture.
Separate a replacement request from a redesign request. Replacing a worn bag while keeping the same specification is different from switching to another construction or changing dimensions. If you want a change, identify it explicitly so the supplier does not quote an assumed equivalent.
The EXTRACTPHYTO Bubble Bags range includes individual bags and complete sets in Canvas & Mesh and All Mesh constructions. Listed capacities are 1, 5, 10, 20 and 32 gallons. These are catalogue choices, not a guarantee that bags from different suppliers have identical dimensions.
Check physical fit separately from nominal capacity
Use a measurement sheet for the container and the bag. State how each measurement was taken: an unsupported fabric opening, for example, is not the same measurement as a rigid container rim. Do not stretch a bag to obtain a target dimension.
| Record | Why the supplier needs it |
|---|---|
| Container manufacturer or drawing reference | Identifies the vessel against which fit must be checked. |
| Inside opening and outside rim dimensions | Distinguishes the space inside the vessel from the rim the bag must accommodate. |
| Container depth and taper | Helps assess whether the proposed bag shape is appropriate. |
| Bag opening, base dimensions and finished depth | Allows comparison with the supplier’s drawing using agreed measurement points. |
| Cuff and drawstring arrangement | Identifies how the opening is retained and how much material is needed around the rim. |
| Other bags used in the same assembly | Flags a need to check the assembled fit, not just one bag in isolation. |
Include photographs with a ruler for orientation, but use written measurements as the order reference. Ask the supplier to state dimensional tolerances rather than inventing an acceptance allowance after delivery.
Match the written micron specification, not just the color
EXTRACTPHYTO lists 25, 45, 73, 90, 120, 160, 190 and 220 micron options. Specify the required rating on every purchase-order line. Color is useful for identification within an agreed product range, but a color match between suppliers does not prove a specification match.
A useful stock description combines capacity, construction, micron rating and revision. Keep the supplier’s item code alongside your internal stock code. This makes a later reorder more precise than a description such as “the yellow replacement bag.”
Approve a sample before committing to a new bulk replacement
When changing suppliers or dimensions, request a sample of the proposed production specification. Check the container fit, cuff position, bag depth, identification and compatibility with the remaining set. Record the result against the container reference and sample revision.
If the sample does not fit, send the measured discrepancy and photographs. Agree the correction in writing. Keep the approved sample or its documented specification available for receiving inspection; a different bag from the same catalogue is not automatically an equivalent reference.
For an example of a separately listed item, see the 5 gallon All Mesh single bag. Confirm which accessories, if any, are included with the exact order line rather than assuming a single replacement includes everything shown with a full set.
Build a replacement order that is easy to repeat
Use one line per specification, with quantity expressed as individual bags or sets. Separately list sample cost, minimum order quantity, lead time, packaging and shipping terms as items for the supplier to confirm. No universal replacement interval or standard minimum order should be assumed.
For distributor inventory, track demand by the actual replacement SKU. Use your own reorder history and agreed supply lead time to decide stock levels. A popular complete set does not establish how many replacements of each micron rating your customers will need.
Questions buyers ask
Will any 5 gallon bag fit my existing 5 gallon container?
Do not assume so. Compare dimensions and cuff construction, then approve a sample where compatibility is important.
Can I mix All Mesh and Canvas & Mesh bags?
Treat this as a configuration change requiring a fit and application review. The construction name alone does not establish compatibility.
What should I send for a replacement quote?
Send the existing reference, capacity, micron rating, construction, container measurements, bag measurements, photographs and quantity per specification.
Request a matched replacement quotation
EXTRACTPHYTO is a China-based manufacturer offering individual bubble bags, sets and OEM options. Review the available bag constructions and capacities, then send your replacement specification for a quotation. Include destination country, sample requirements and any label or packaging needs so compatibility and commercial terms can be confirmed before ordering.
