Product Overview
ZRLEI 400cc Oxygen Absorbers are a bulk food storage supply, with 100 absorbers split into 20 heat-sealed five-packs. Each 400cc absorber is designed to remove oxygen from airtight containers like 1-gallon Mylar bags, which can help extend the shelf life of dry and dehydrated foods.
This review checks the capacity, packaging approach, food contact safety claims, and practical fit for common long-term storage tasks shown in the listing.
Score Breakdown
This verdict is based on the manufacturer's stated specifications, the current Amazon listing and its product images, the confirmed materials and design, real buyer ratings, and our research into the product category. Scores are consistent editorial judgments, not laboratory measurements, and we did not receive a paid sample.
Key Features
Absorbs roughly one fifth of air volume, suited for 1-gallon Mylar bags and similar airtight containers.
Packaging uses food-grade material and passed strict food testing for safe storage with dry foods.
Double-layer construction with an anti-oil film helps keep absorbers intact during storage and handling.
Absorbers are packaged in sets of five and heat sealed immediately after production to limit oxygen exposure.
Works with grains, beans, powders, pastas, cereal, dehydrated and freeze-dried foods in airtight containers.
Design and Build Quality
The absorbers come in five-count packs that are heat sealed immediately after production, which is meant to keep unused absorbers from reacting with room air before you need them. The listing states these packs are never repackaged, a detail that supports potency if handled correctly.
Each absorber uses food-grade material with a double-layer, anti-oil-film design, so it can be placed directly with dry foods. The product note clarifies that bags will not shrink like vacuum packaging, because oxygen makes up only about 20 percent of air.
Performance in Everyday Use
The 400cc size is matched to 1-gallon Mylar bags and other airtight containers, and the listing indicates it is appropriate for grains, beans, powders, pastas, cereal, dehydrated and freeze-dried foods. Removing oxygen can slow spoilage and help preserve dry goods for long-term storage.
A key limitation is that oxygen absorbers do not remove all air, so containers will not visibly shrink like vacuum bags. You still need a properly sealed airtight container, and once a five-pack is opened, the remaining absorbers should be used quickly or resealed in an oxygen barrier to avoid losing capacity.
How It Performs: The Evidence
| Decision factor | What we found | Evidence and measurement | Score | Why it matters |
|---|---|---|---|---|
| Oxygen Absorption Capacity | 400cc per absorber | Listing states 400cc capacity suited for 1-gallon Mylar bags | 8.0 | Appropriate for common dry storage containers but only removes oxygen, not all air. |
| Food Safety | Food-grade material, strict food testing | Feature bullets state food-grade packaging and passed strict food testing | 8.5 | Clear food contact safety claims, though no third-party cert shown. |
| Packaging Freshness | Heat-sealed five-packs, never repackaged | Listing says absorbers are packaged and heat sealed immediately after production | 8.5 | Reduces oxygen exposure before use, but no opened-pack shelf life data. |
| Ease of Use | Requires airtight container, bags won't shrink like vacuum | Product note clarifies oxygen is 20 percent of air | 7.5 | Straightforward but users must work quickly after opening a five-pack. |
| Container Fit | 1-gallon Mylar bags and similar airtight containers | Feature bullets recommend 1-gallon Mylar bags | 8.5 | Well matched to common long-term storage setups. |
Who Should Buy It

This review is based on the manufacturer's stated specifications, the current Amazon product listing and its images, the confirmed materials and design, and our own research into food storage and preservation as a product category. Our scores are editorial judgments made against consistent criteria, not laboratory measurements, and we did not carry out destructive or long-term stress testing.
Where the listing did not clearly confirm a detail, such as exact dimensions, weight or certifications, we have deliberately left it out rather than guess. If you are buying, always confirm the current specification and price on the live Amazon listing, since configurations and availability change.
